Construction method of underground continuous pouring concrete pile wall
The invention discloses a construction method of an underground continuous pouring concrete pile wall, and belongs to the technical field of building foundation pit supporting. Drilling a plurality of A pile holes by using a drilling machine and filling the A pile holes with slurry; steel cylinder models are placed in all the A pile holes; a B1 pile hole is drilled between the A1 pile hole and the A2 pile hole to the designed depth, a B2 pile hole is drilled between the A2 pile hole and the A3 pile hole to the designed depth, slurry is injected into the B1 pile hole and the B2 pile hole, then the steel cylinder model in the A1 pile hole is pulled out, a steel circular protection cylinder is placed in the A1 pile hole, then the steel cylinder model in the A2 pile hole is pulled out, then the steel circular protection cylinder is placed in the A2 pile hole, and so on, and the pile hole is formed. Until the last steel circular pile casing is put into the An pile hole; and after concrete is poured into the B1 pile hole, a reinforcement cage is placed in the A1 pile hole and concrete is poured into the A1 pile hole, the steel protection cylinder in the A1 pile hole is pulled out, the concrete of the A1 pile and the B1 pile is connected into a whole before solidification, and the like, until overall construction of the concrete pile wall is completed. The construction method is used for construction of the underground continuous pouring concrete pile wall.
地下连续灌注混凝土桩墙的施工方法，属于建筑地基基坑支护技术领域。利用钻机钻进多个A桩孔并注满泥浆；在所有A桩孔内放入钢筒模型；在A1桩孔与A2桩孔之间钻进B1桩孔至设计深度，在A2桩孔与A3桩孔之间钻进B2桩孔至设计深度，向B1桩孔及B2桩孔内注入泥浆，然后，拔出A1桩孔内的钢筒模型，在A1桩孔内放入钢圆护筒，之后，拔出A2桩孔内的钢筒模型，再在A2桩孔内放入钢圆护筒，依次类推，直至将最后一根钢圆护筒放入An桩孔内；在B1桩孔内灌注混凝土，在A1桩孔内安放钢筋笼并灌注混凝土后，拔出A1桩孔内的钢护圆筒，使A1桩和B1桩的混凝土在未凝固前连成一体，依次类推，直至完成混凝土桩墙的整体施工。本发明用于地下连续灌注混凝土桩墙的施工。
