Efficient rock entering construction method for rock-socketed underground diaphragm wall
The invention relates to the technical field of underground diaphragm wall construction, and particularly discloses an efficient rock-entering construction method for a rock-socketed underground diaphragm wall, which comprises the following steps of: after construction of a guide wall and various construction preparatory works are completed, sequentially adopting hydraulic grab bucket grooving and soft soil digging, rotary digging and two-hole one-milling construction of a rock stratum by adopting a slot milling machine, and cleaning holes and replacing slurry by utilizing the slot milling machine. Lowering a reinforcement cage and a joint pipe, and pouring underwater concrete; the tooth distribution structure and the operation method capable of rapidly entering the rock are invented for the grooving process in the rock stratum, engineering practice proves that the grooving time in the rock stratum can be shortened by more than half by adopting the method, the efficiency is high, the cost is low, and the cost reducing and efficiency increasing effects are remarkable.
本发明涉及地下连续墙施工技术领域，具体公开了一种嵌岩地下连续墙高效入岩施工方法，在完成构筑导墙及各项施工准备工作后，先后采用液压抓斗成槽及挖软土，旋挖和铣槽机二孔一铣施工岩层，利用铣槽机清孔换浆，下放钢筋笼和接头管，浇筑水下混凝土；本发明针对岩层中的成槽工艺发明了能快速入岩的布齿结构和操作手法，经工程实践证明，采用此方法可以将岩层中成槽时间压缩一半以上，效率高、成本低，降本增效效果显著。
