Carrier pile construction method for water-rich stratum
The invention discloses a carrier pile construction method for a water-rich stratum, and belongs to the technical field of foundation construction. The method comprises the following steps: S1, forming holes above an impermeable layer; s2, a bottom opening of the pile casing is tightened, and the pile casing sinks into a pre-sunk hole; s3, a brick plug is formed at the bottom opening of the pile casing; s4, the brick plug is tamped by a tamper, and the pile casing is brought to the designed pile bottom depth; s5, the brick plug is knocked out of the bottom opening of the pile casing through a rammer, and dry and hard concrete is put into the pile casing for ramming; s6, a reinforcement cage is installed; and S7, pile body concrete is poured, and a carrier pile is formed. According to the method, the bottom opening of the pile casing is tightened, and the brick plug is formed at the bottom opening of the pile casing, so that when carrier pile construction is carried out in the water-rich stratum, sudden gushing is prevented, confined water is prevented from entering the pile casing to cause construction difficulty, the influence on the construction quality is avoided, the method is simple and easy to operate, the water-rich stratum carrier pile hole forming efficiency can be effectively improved, the construction progress can be accelerated, and the construction cost is reduced. The construction cost is saved.
本发明公开了一种用于富水地层载体桩施工方法，属于地基基础施工技术领域。该方法包括：S1：在不透水层以上成孔；S2：将护筒底口扎实，沉到预先沉好的孔中；S3：在护筒底口形成砖塞；S4：夯锤夯击砖塞，将护筒带至设计桩底深度；S5：夯锤将砖塞击出护筒底口，并投入干硬性混凝土夯击；S6：安装钢筋笼；S7：浇筑桩身混凝土，形成载体桩。本发明中，将护筒底口扎实，在护筒底口形成砖塞，从而在富水地层内进行载体桩施工时，防止突涌，避免承压水进入护筒造成施工困难，并且避免影响施工质量，该方法简单、易操作、能够有效的提高富水地层载体桩成孔效率，能加快施工进度，节约施工成本。
