Hole-forming construction method for pile foundation in karst area
The invention relates to a karst area pile foundation pore-forming construction method, and relates to the technical field of bridge construction, and the karst area pile foundation pore-forming construction method comprises the following steps: protective excavation: arranging a sleeve in the soil in a penetrating manner in the vertical direction to form a pore channel, and excavating out the soil in the sleeve; rock digging is conducted, lava in the karst area is crushed, and the crushed lava is taken out of the sleeve; a reinforcement cage is placed, and the reinforcement cage is arranged in the sleeve in a penetrating mode; and concrete is poured, specifically, the concrete is poured into the hole channel, then a pile foundation is formed in the hole channel, and in the concrete pouring process, the sleeve is gradually pulled out of the hole channel along with the rising of the liquid level of the concrete. The probability of collapse of the inner wall of the hole channel can be reduced, and then the quality of a finally-formed pile foundation is improved; and compared with a traditional construction technology, the construction efficiency is improved, the construction difficulty is reduced, and surrounding buildings are protected.
本申请涉及一种岩溶区桩基成孔施工方法，涉及桥梁施工的技术领域，其包括保护挖土，沿竖直方向将套管穿设在土壤中，进而形成孔道，并将套管内部的土壤挖出；挖岩，对岩溶区的熔岩进行破碎，并将破碎的熔岩从套管中取出；安放钢筋笼，将钢筋笼穿设至套管中；浇筑混凝土，向孔道中浇筑混凝土，进而使孔道中形成桩基，在浇筑混凝土的过程中，随着混凝土的液面的提升逐渐将套管从孔道中抽出。本申请能够降低孔道内壁坍塌的概率，进而提高最终形成的桩基的质量；而且本申请相比与传统施工工艺，提高了施工效率，降低了施工难度，保护了周边的建筑。
