Double-wheel milling deep mixing cement soil underground continuous wall construction method
The invention discloses a double-wheel milling deep stirring cement soil underground diaphragm wall construction method. The method comprises the steps that the position and wall body parameters of a to-be-constructed underground diaphragm wall are obtained; a guide hole is formed in the position of the underground diaphragm wall to be constructed and backfilled, and parameters of the guide hole are determined according to wall body parameters; and constructing the underground diaphragm wall conforming to wall body parameters at the position of the underground diaphragm wall to be constructed after the guide holes are backfilled by using double-wheel milling deep stirring equipment and cement grout. According to the double-wheel milling deep stirring cement soil underground continuous wall construction method, the hole guiding procedure is additionally arranged, so that in the wall forming construction process of an underground continuous wall, when the underground continuous wall encounters a hard stratum with the standard penetration impact number larger than 40, the cutting and digging difficulty is reduced, the pressure of a hydraulic system in the drilling process is reduced, the service life of construction equipment is prolonged, and the construction speed is increased.
本发明公开了一种双轮铣深层搅拌水泥土地下连续墙工法，包括获取待构筑地下连续墙的位置及墙体参数；在待构筑地下连续墙的位置处开设引孔并回填，引孔的参数根据墙体参数确定；在回填引孔后的待构筑地下连续墙的位置处，利用双轮铣深搅设备和水泥浆液，构筑符合墙体参数的地下连续墙。本发明的双轮铣深层搅拌水泥土地下连续墙工法，通过增设引孔工序使地下连续墙在成墙施工过程中，遇到标贯击数大于40的硬质地层时削掘难度减小，降低下钻过程中液压系统压力，延长施工设备的使用寿命，提高施工速度。
