Milling, deep-layer, stirring and curing waterproof curtain and construction method for combining waterproof curtain with rotary excavating pile
The invention relates to the technical field of foundation pit supporting construction, and discloses a milling, deep-layer, stirring and curing waterproof curtain and a construction method for combining the waterproof curtain with a rotary excavating pile. The waterproof curtain comprises a curing agent and the rotary excavating pile. The curing agent is prepared from the following components: 25-35 parts of cement clinker, 6-10 parts of quick lime, 20-30 parts of fly ash, 12-20 parts of desulfurized gypsum, 15-25 parts of superfine slag powder, 2-5 parts of sodium dodecyl benzene sulfonate, 2-5 parts of sodium carbonate, 1-2 parts of an expanding agent and 2-5 parts of a high-efficiency water reducing agent. The curing agent is mixed with water according to the raw material ratio to prepare curing agent slurry, the curing agent slurry is mixed with a soil body of a soil body groove and then solidified to form a diaphragm wall, and the diaphragm wall is cut by a milling device to form a spiral U-shaped groove. Compact and firm occlusion connection is achieved through the inner wall structure of the U-shaped groove and the rotary excavating pile, and the curtain structure with the supporting and waterproofing effects is formed. The construction difficulty and the construction cost are effectively reduced through optimized construction measures of mixing the curing agent slurry, synchronously manufacturing the soil body groove and supplementing the slurry, manufacturing the diaphragm wall, manufacturing a pile hole and manufacturing the waterproof curtain.
本发明涉及基坑支护施工技术领域，公开了铣削深层搅拌固化止水帷幕及与旋挖桩联合的施工方法，包括固化剂和旋挖桩。所述固化剂的成分包括水泥熟料25‑35、生石灰6‑10、粉煤灰20‑30、脱硫石膏12‑20、矿渣微粉15‑25、十二烷基苯磺酸钠2‑5、碳酸钠2‑5、膨胀剂1‑2、高效减水剂2‑5。所述固化剂按原料配比与水混合拌制成固化剂浆液，所述固化剂浆液与土体槽的土体混合后凝固成防渗墙，所述防渗墙通过铣削装置切割形成有螺旋形的U型槽。通过U型槽内壁结构与旋挖桩实现紧凑、牢固地咬合连接，形成具有支护与止水效果的帷幕结构。通过固化剂浆液的拌制、同步制作土体槽和补充浆液、制作防渗墙、制作桩孔及制作止水帷幕的优化施工措施，有效降低施工难度和工程造价。
