This article analyses how to combine the local economic development status and topographical features make “western China tourism leisure”, and to build green, humanity travel resort related Suggestions.

Along with the economic and social development and people living standard rise ceaselessly, tourism and leisure share will improve, HuaYin city offered to strive to create “western China tourism leisure”. Is to put the HuaYin to a higher level position. This paper is how to better and faster create “leisure”, do some preliminary exploration and thinking.

A, “tourism leisure” to highlight a “scene” word.

HuaYin huashan have not only, still have the abundant tourism resources; HuaYin mountain without water, the mountain limited capacity; Mountain scenic spot is many, it looks very little. We should change the thought, down in the tourism resources development of the new world, in orbit around the huashan mountains on supporting the. In recent years, HuaYin tourism industry though obtained fast development, but HuaYin besides mountain scenic spot the rich, the little, although have spots, many did not develop. Therefore, puts forward that we should change the past “mountain, the expansion LiuKe” for “mountain scenery, the LiuKe”. Because, the landscape, the mountain is not so easy expansion, lane is bad to also can destroy the landscape. Thus shall be under the mountain scenery fluctuation kongfu. Together with the cable and west Tong high-speed built, tourists come, easy go. Should try to let visitors at the foot of the stay for longer, can achieve stimulating consumption, increase the income, the purpose of the boom of the local economy. Rivers, is a place where the basis and premise of scenery graceful. Advice to build “too China lake” (building city river park is very good). Can store water, make full use of the water resources development of tourism industry, huashan feet for XinJing add, is a flood control and security project. In the long run, the lake also with formation water resources recycling use groundwater. Natural scenery, man-made, shenzhen has “splendid China”, yunnan has “the world horticultural exposition”, “east capital” to have a “peony”, we HuaYin can also make “Chinese rose will”. “Mountain flower ecological demonstration garden”. In expanding the huashan mountains in time and extension.

Second, leisure tourism to highlight a “green” word.

First of all, have to “green”. Must be advocating healthy diet, ecological diet, the development of the local characteristics snacks. So, we should let visitors can eat and relaxed, and let visitors safe to eat. This will give our guesthouse, hotel, restaurant industry given strict requirements.

Second, live to “green”. Now, people living environment, do not have to how high-grade hardware. For example, the hotel room in place some high-grade, rare flowers, can a pleasing to the eye, and also can purify air. Three is to do a “green”. HuaYin as the ancient city of xi ‘an “back yard garden”, as “the first city of its central” to have green, as leisure travel more to have green. HuaYin people much less, but non-cultivated land area is really many, planting trees that can generate economic benefits, the more important and ecological benefit, tourism benefits, environmental benefits.

Three, leisure tourism to put an end to a “dirty” word.

Due to the influence of the traditional economic growth view, tourism activities, from the overall still not completely out of the extensive development mode, lead to landscape ecological degeneration of low quality, unsustainable phenomenon. HuaYin can be called a is rapidly emerging tourist city. Investment promotion, expand the development, is undoubtedly correct, but, must can’t make what “pollution investors”

, pollution small also can’t have. As a “tourism leisure”, more should instead be attention, take excellent care.

Four, leisure tourism mining a “culture” word.

Known as a “shaolin temple” of the movie, the tourist industry of songshan forward into a new climax; A AWu singing than the have a beautiful place “, become the pronoun of yunnan scenery, masterpiece. We mountain, the “HuaYue fairy palm”, “chess pavilion”, “mountain, high precision”, which can be a world of mind “advocate” or mountain, the representative? Reason is the lack of big, high-level and celebrities, drama, the card’s marketing campaign, even a decent “CD” also have no.

In recent years, “shaanxi HuaYin old chamber group” in Beijing after the popular, to HuaYin tourists want to enjoy HuaYin old chamber, it is not easy.

Many historical allusion huashan feet, cultural landscape, but the lack of mining and the integration. West YueMiao within the “the first one pillar”, if no one explanation, who can be seen; YangZhen “hang down the SiZhi”, not even a inscription also have no, only one is not like the landscape of the portrait, the young’s “innocent ChuanGu” in the contemporary incorruptness construction and anti-corruption tide, only the city’s only recently did a “SiZhi” web site. “A cypress a stone at the well” is a rich in poetic humanities landscape of, now but water Withers, cypress died, ShiFei……. So HuaYin heavy historical and cultural brilliance, urgently awaits to development.

Construction “western China tourism leisure”, it is to need through the long-term efforts. But, as long as we stick to the scientific development, harmonious development, cross-realm development idea not be moved, a new hope HuaYin-the charm of “west China tourism leisure”, will quickly, on the track of healthy development.

　Seepage of hydraulic structure over the years has been the construction of water projects which are particularly important elements in the construction, when the underlying soil is poor permeability when strong, great harm to the Foundation under the action of water flow. Therefore became a hydraulic seepage engineering in construction section not to be ignored. This article provides a brief introduction to several seepage prevention technology.

　　1 high pressure Jet Grouting technology
　　
　　In embankment seepage control engineering, maintenance of high pressure Jet Grouting technology as compared to conventional concrete cutoff wall can reduce construction cost in varying degrees, with a small amount of excavation, construction convenient, covering less, little influence on adjacent buildings and so on. This technology greatly improves River, River, Lake, reservoir, Canal seepage control of dike resilience, ease the pressure of flood control, to protect the lives and property of the people and the socio-economic development will play a positive role in the social benefits are obvious.
　　1.1 drilling: Rotary mud solid wall (or impact) of drilling. Hole filling and sealing in the process, make holes in the mud to maintain normal circulation, outside the back out of the hole, until the final hole; drilling with casing. Side edge drilling into the casing until the final hole. Attention ensure rig a vertical drilling, on the slope should be ≤ 1%; into the ejector rod under: drilling mud wall can be sprayed directly down into the hole, until the end of the hole.
　　1.2 construction of high-pressure Jet Grouting technology
　　Construction technology used in the parameter varying according to the use of high pressure Jet Grouting method. The Grouting pressure used by different lift speed is also different. On the various strata, if used with a construction method of hydraulic pressure, air pressure, slurry of little change, only larger lifting speed changes, are main factors affecting the high-quality spray. Under normal circumstances, determine lift speed should note the following issues: varies by formation, slightly faster upgrade speed can be in the sand, sand-egg (conglomerate) should slow down in the rock, containing large stone (above 40cm) stone or rock formation of focus should be more slow; vary according to the sequence. Sequence hole before lifting speed is slower, latter foreword hole relatively faster; high pressure Jet Grouting in construction of times slow lifting speed reduction in hole found and returned to pulp.
　　1. 2.1 determination of wall location
　　Flat site according to design requirements, requiring ground underground barrier-free, for some jobs Foundation soft, uneven, potentially causing lots of accident caused by the machine turned over, be sure to take preventive measures, on the flat ground on the central line for survey positioning of wall.
　　1. 2.2 management of spray-wall
　　Speed should be well controlled excavation and Grouting pressure, increase speed, aspirated volume size should make the grout into the boiling. Filling phase segregation and does not allow broken pulp slurry cannot occur, ensure uniform wall without interlayer, pipe plug or is otherwise brief downtime occurs, should quickly repair.
　　
　　2 General Grouting strengthening technique of leakage
　　
　　2. 1 introduction of Grouting strengthening technique of leakage
　　2. 1. 1 dam curtain Grouting for dam Foundation of the body, mainly filling gaps and cracks, seepage cutting leakage through Grouting into seepage. This method applies to the grouted rubble gravity dam.
　　2. 1. 2 consolidation Grouting of dam upstream face; plug the loopholes and gaps, the reinforcement of dam body seepage control performance and improve, to further increase the bearing capacity and integrity of the dam.
　　2. 1. 3 consolidation Grouting of dam downstream face tracking; in downstream dam surface where there is leakage or corrosion of the Plaza, resulting in horizontal holes or holes, bury grout injection tube Grouting to plug the leak channels and cavities, cracks of dam, reinforcement of dam, increase dam stability and erosion. This back-filling process, very suitable for the arch and buttress dam, set on uplift pressure of gravity works only understood and drainage holes can also be used. This approach is best when the dam without water.
　　2. 1. Tick Tick 4 dam surface back seam; tick seam, high grade cement mortar, dry-shrinkage of cement mortar or high grade cement mortar joints with waterproof material, improving the ability of dam face seepage and dam stability, integrity, and resistance to freezing and thawing, storm brushing resistance capacity. This method is “blocking, stop, back track before” method of reinforcing Grouting in leakage.
　　2. Grouting strengthening technique of leakage of 2 principles of bore hole and the hole
　　2. 2. 1 bore hole curtain grouting, leaking Dam along the crest of the centerline, 50mm or 75mm to pitch 3M, Aperture, or under test to determine the pitch. Following 1M–2m in water leakage of deep hole drilling to parts, such as the rock of contact with or leakage, drill can drill to impervious bedrock the following LM–2m. Hole to hole at once, can also be ordered pore, pore, segmented sea pulp subparagraph shattered area from top to bottom, while at the 5-7 day after solidifying slurry, then continue to drill down, to prevent drilling, drill accident. Contacts and in three Gorges Dam and dam Foundation grouting, may also take the upstream dam slant the foot or vertical holes Grouting leaking, but should first clear the base before the hole, pouring of dam feet 0. 3M part. 5m thick concrete, solidification and punch again. Vertical or inclined less than 5. Curtain Grouting of hole deviation shall not be greater than the value of their holes to specified value.
　　2. 2. 2 dams upstream consolidation Grouting Boucon; leaking site “plum blossoms”, drill spacing and row spacing LM–3M, determined in accordance with water leakage, drilling location selected in the stone “” crack; cracks in parts can be emplaced along cracks LM and one hole. Aperture is 42mm, the hole depth 0. 7m——1． 5M, based on the actual situation determine the dam.
　　2. 2. Consolidation of dam downstream face tracking in 3 short for the Zihe River pulp Boucon; per 1M a hole in the crack sites along the gap; in other parts of water seepage, in accordance with the “plum blossom”-bore hole, row spacing and pitch 2m–3M, bore hole location? ” T “slot, or appropriate encryption bore hole. Hole depth and diameter with the dam upstream face.
　　2.3 construction requirements
　　2.3.1 first venting or lowered the water level of reservoir filling parts of the following, then grouting, and filling the record.
　　2. 3. 2 flushing; before filling should flush the hole wall, bottom hole and crack, adopts Feng Shui combination flushing, filling pressure of 75% water pressure is not more than this paragraph, to hole depth to determine the time, until back to clear water.
　　2. 3. 3-dimensional curtain Grouting; ① adopt hole round robin, top down or bottom up paragraph filling, and finally bored. Segment when filling, in the above paragraph by pulp Oo5m extra rubber sealing. Through argument, can also be closed using small diameter drilling hole Grouting; ¢á dam body filling length, about a shipment of 5NT better hole depth of not more than 8M, the whole hole disposable infusion; ⑧ Grouting pressure control as designed, but lower than the limit pressure lift test, general control of 0. 2MPa——0． 4MPa。
　　2. 3. 4 dam surface consolidation and tracking Grouting; ① in hole within pre-buried note pulp tube, hole mouth tube around with dry hard cement mortar Tiandu, used bore 20mm pipe, long 50cm, insert hole within 40cm, exposed 5Cm “10Cm, tube head to processing silk buckle, to and lost pulp tube connection; ⑦ take a group four hole parallel Grouting method, also can single hole or two hole together perfusion. Focus on dam leakage after key holes to take a single hole Grouting. Design of Grouting pressure control, generally use a 0. 2MPa——0． 25MPa。
　　2. 3. 5 slurry concentration; principles to follow when filling from thin to thick, dense under water pressure test of threaded-modified. When the amount of injection Grouting the dam when greater than 30L/min, Leapfrog deepen. When the slurry bored at a level above 400L, and Grouting pressure and suction volumes without obvious changes, modified slurry bored concentrated level. Ash slurry water than the average weight ratio, 8:1, 3:1,, 1. 5:1, 1:1, 0,8:1, 0. 6:1, 0. 5: 19 levels. By design, if necessary, also be intermingled ash, sand, quartz powder, Aluminum powder and so on. During the filling process, slurry to proportion determination once every hour.
　　2. 3. 6 to 2-3 when filling sequence filling, at the same time to reperfusion must. Design pressure, when the amount of suction is not greater than O. When the 4L/mio, then continued to fight the end of 30 minutes.
　　2. 3. 7 filling Kong Fengkong; when the curtain grouting, vertical bore hole sealing mining. Catheter with machinery, 1:2 cement mortar used up from the bottom gradually enhanced fill-compacting; dam surface of consolidation Grouting of horizontal bore hole sealing, artificial cement mortar with low water-cement ratio 1:2 Tiandu ramming. Best with expansive cement mortar sealing material.
　　
　　3-seepage wall technique
　　
　　Linhe seepage cut-off wall for. Its role is to reinforce the dike, lower dam saturation line release point to ensure dam safety.
　　Seepage interception wall technology is divided into two: one is the cost of cement-soil seepage interception wall minimum; one is the concrete cutoff wall, its slightly higher cost than cement-soil seepage interception wall. Concrete cutoff wall is slotted on the ground (hole) of construction on the ground to mud wall, holes dug trench or chain-shaped hole pile, backfill impervious material, built with impervious performance of diaphragm wall. Technology of cement-soil mixing pile cutoff is to use multiple small-diameter deep agitator with mud to spray water into the formation and mixing cement soil, with cement as the curing agent, curing agent and soil physico-chemical reaction occurs between, making the soil into good integrity, stability, impermeability, and have a certain strength of cement-soil seepage interception wall, to achieve the purpose of cutoff.
　　Advantages: low construction cost, covering less, faster construction progress.
　　Disadvantages: cutoff wall for underground engineering, construction technology for complex, high technical requirements, especially at the time of Foundation soil complex and prone to unexpected problems in the construction, construction caused disruption. Concrete cutoff wall is also prone to trench collapse, leakage, wall joints with mud wall grooves transverse tilt leather jacket layer, technical problems, pending further analysis and study.
