Construction method of reinforced concrete cast-in-place pile under complex geological conditions
The invention relates to the technical field of building construction, in particular to a construction method of a reinforced concrete cast-in-place pile under complex geological conditions, which comprises the following steps: S1, leveling a site, and paying off a pile position; s2, hole forming and soil taking are conducted, and a steel casing is installed to the position X m away from the natural terrace; s3, slurry retaining wall construction; s4, rock entering, pipe pulling and hole cleaning; s5, placing a reinforcement cage; s6, concrete pouring; and S7, post-grouting, inspection and acceptance. The steel casing and slurry retaining wall cast-in-situ bored pile construction technology is adopted, the problems that under the complex geological conditions of the super-thick coal ash layer, a cast-in-situ pile is prone to hole collapse and drill burying, hole collapse due to vibration during rock entering, water source shortage, serious water leakage, poor retaining wall forming and the like are solved, the cost and the working intensity are greatly reduced, and the construction efficiency is improved.
本发明涉及建筑施工技术领域，更具体而言，涉及一种复杂地质条件下钢筋混凝土灌注桩施工方法，包括：S1、场地平整、桩位放线；S2、成孔、取土、安装钢护筒至距自然地坪X米处；S3、泥浆护壁施工；S4、入岩、拔管、清孔；S5、安放钢筋笼；S6、混凝土浇筑；S7、后注浆、检验验收。本发明采用钢护筒+泥浆护壁钻孔灌注桩施工工艺，解决超厚粉煤灰层复杂地质条件灌注桩成桩易塌孔埋钻、入岩时振动塌孔、水源紧缺且水渗漏严重、护壁成型差等难题，极大地降低成本和工作强度、提高施工效率。
