2.2. Project Overview and Main Quantity of Work
2.1.Project OverviewThe Section Line from the west, east junction, line starting point measurement pile number BI001 (horizontal coordinate y = 17651070.38, longitudinal coordinate x = 4306681.26), the end of the measurement pile number BJ001 (horizontal coordinate y = 17720225.57, longitudinal coordinate x = 4258240.82), after the line adjustments, the final length of the line 89.4008km.The section Most of the line along the plains, mainly including alluvial plains and alluvial inclined plains, low hills and hilly areas are mainly concentrated between BI018#pile ~ BI022#pile, mainly to the high mountains. Hydraulic protection mainly protects slopes and banks for river and gully crossing, and makes retaining walls and drainage ditches for steeper hills. For earth canals and steep slopes, retaining walls are set up; for riverbanks with unstable soil and serious scouring by the main river, measures of retaining walls are taken; for riverbanks or beaches with smooth water flow and very little scouring, slurry masonry schist berms can be used. For the clay soil bank, take layered tamping backfill measures (tamping coefficient is generally 0.90); pipeline climbing embankment laying, the water-side (or both sides), the river bank using slurry masonry schist berms, for the original on the masonry of the river or cement masonry, take the same way with the original masonry to restore the original appearance; for the angle of the slope is greater than 15 ° of the mountain slopes every 10m to do retaining walls and drainage ditches.

3.2. construction method water protection project monolithic project volume is small, at the same time, in order to avoid damage to the pipe body, the construction of manual excavation pit slot, the rock section, take the method of artificial rock drilling wall embedded groove. Submersible pumps are used for pit descending, generators are used for on-site power generation, slurry masonry is used for artificial masonry, and mortar is used for on-site mold support.
4. construction technology measures
4.1. material selection and technical requirements of hydraulic protection is the line project protection facilities, the pipeline use process protection is of great significance, so the technical requirements of the materials used for hydraulic protection is very strict, must be strictly selected and accepted. Material procurement adhere to the local conditions, quality assurance, cost reduction principles, incoming materials must have material certificates, certificates of conformity and related certificates, prohibit unqualified products, unlicensed products into the construction site.
4.1.1. Masonry stone masonry stone (mainly blocks) selection of uniform texture, hard, no cracks, not easy to weather the stone, stone surface without weathering debris, mud, dirt, the stone to be used in the compression test, the ultimate compressive strength should be more than 25Mpa, try to choose a larger stone masonry, blocks should be roughly square, no front flute convex angle, the top surface and the ground should be more Flat, its thickness should not be less than 20cm, width and length are not less than its thickness. Slabs should have two roughly parallel surfaces, its thickness should not be less than 15cm, one of the side length of not less than 30cm. West-East Gas Pipeline water protection stone to block stone-based, construction section of the stone area is mostly weathered stone, does not meet the technical requirements of the water protection masonry, so the construction of the stone to be purchased mainly to buy the location selected in Shandan County quarry, the distance between the nearest 26Km, the furthest distance of 82 kilometers, the use of dumper trucks Transportation.
4.1.2. Masonry mortar? First of all, according to the design requirements of the selection of qualified sand and cement, mortar mixing to use tap water, with 5T tanker trucks from Shandan County to buy and send to the site, the average transportation distance of 38Km, is strictly prohibited anywhere in the ditch to take the sewage. Cement with R425 ordinary silicate cement, purchased in Shandan Cement Factory, the cement must have factory certificate, test report, re-inspection report, its stability, setting time, strength and other indicators must be in line with the standard provisions of the average transportation distance of 39Km.? Sand adopts washed medium (fine) sand, purchased by Sandan sand field, the mechanical properties of sand and gravel and other indicators in line with the standard provisions before being put into use, the average transportation distance of 29Km. Construction site using cement stacked neatly, bagged cement stacking height is generally no more than 10 packages, stacking width to 5-10 bags as a limit, temporary open-air stacking should be covered with a rainproof tarpaulin.? The storage time of cement is generally not more than 3 months, when there is doubt and uncertainty about the quality of cement, review the test before use and use it according to the test results. The sand and cement used on site are stacked separately and neatly, and are not allowed to be mixed, and the sand is kept clean, and is strictly prohibited to be mixed with soil. Slurry masonry mortar must have when the fluidity and good compatibility, to ensure that the masonry mortar joints are fully filled and compacted. Simple on-site inspection method is to pinch the hand into a small group, to seal the finger without pulp, after letting go of the hand is not loose as qualified. Different construction parts, structural form of masonry mortar standard strictly in accordance with the design requirements for control, slurry masonry wall masonry is strictly prohibited the use of mixed mortar. Masonry mortar should be quantitative batch strength test, up to 100m3 masonry to do a group of evaluation of mortar strength specimens. When the cement varieties, standard or with changes in the ratio, should be another group of specimens, and as a measure of the quality of mortar based.
4.1.3. planks? Planking choice by place, the principle is that it must be hardwood, we choose a better texture of pine, wood from Zhangye City timber market. Cut-off wall vertical plate and wall plate connection using just nail.? Plank lagoon hole drilling using electric drill, drilling position and plank connection joints should be staggered, spacing 200mm.
4.1.4. masonry mortar? West-East gas pipeline water engineering gray cut-off wall gray soil using 3:7 gray soil, gray soil mixing before, shall be on the lime, soil, mixing water strict inspection, sampling and testing, laboratory tests can only be carried out after the gray soil preparation. Gray soil mixing using mechanical mixing, mixing to be uniform, each batch of gray soil should be in proportion to the sample check to ensure that the moisture content of the optimal moisture content, the scene to "hold the hand into a ball, the ground blossom" test as a standard. Layers should be used to compact, 30cm layer is appropriate, compaction factor ≥ 0.94.? This section of the water protection is mostly in the Gobi deserted beach and rocky lot, gray soil mixing with fine soil on-site soil extraction is difficult, must be bought from the local soil, according to the combination of the local government, choose the Shandan brickyard soil pit as a land, using dump trucks for pulling the soil, the average transportation distance of 32km.
