Rapid construction method for diaphragm wall in complex stratum with soft upper part and hard lower part
The invention discloses a rapid construction method for an underground diaphragm wall of a complex stratum with a soft upper part and a hard lower part, the underground diaphragm wall comprises an upper silt stratum and a lower rock stratum, the underground diaphragm wall is formed by splicing a plurality of underground diaphragm wall groove sections, and the rapid construction method for the underground diaphragm wall of the complex stratum with the soft upper part and the hard lower part comprises the following steps: S1, surveying and setting out; s2, drilling exploration is carried out; s3, groove wall reinforcement treatment is carried out; s4, construction of a guide wall structure; step S5, slurry preparation; s6, groove section excavation is carried out; s7, a reinforcement cage is manufactured and hoisted; s8, convex steel box treatment; s9, a guide pipe is put down, hole cleaning is conducted, and concrete is poured; and S10, detecting the underground diaphragm wall. The method can effectively solve the problems that the excavation difficulty of muddy soil, sandy soil, rock strata and other geologies during underground diaphragm wall construction is large, the groove wall is extremely easy to collapse, mud or sand clamped in the underground diaphragm wall leaks, and the safety is reduced. The rock strata grooving working efficiency is high, the cost is low, and the equipment loss is small.
本发明公开了一种上软下硬复杂地层地连墙快速施工方法，地连墙包括上层的淤泥质地层和下层的岩石地层，地连墙由多个地连墙槽段相拼接组成，所述上软下硬复杂地层地连墙快速施工方法包括以下步骤：步骤S1、测量放样；步骤S2、钻孔勘察；步骤S3、槽壁加固处理；步骤S4、导墙结构施工；步骤S5、泥浆制备；步骤S6、槽段挖掘；S7、钢筋笼制作与吊放；S8、凸型钢箱处理；S9、下放导管，并进行清孔，浇筑混凝土；S10、地下连续墙检测。本发明可以有效解决地下连续墙施工面临淤泥质土及砂土和岩层等地质开挖难度大，槽壁极易坍塌，地下连续墙夹泥或砂出现渗漏，安全性降低的问题，本发明的岩层中成槽工效高，费用低，设备损耗小。
