Wide-hole-pitch double-high-pressure three-pipe method high-spraying diaphragm wall construction method
The invention provides a construction method of a wide-pitch double-high-pressure three-pipe method high-pressure-spraying diaphragm wall, the diaphragm wall is located on a reservoir dam foundation and is used for performing anti-seepage reinforcement on the dam foundation, and in order to guarantee normal work of an existing water delivery hole of a reservoir, when drilling is performed on a riding track working face, the drilling pitch is larger than the width of the water delivery hole, so that the wide pitch is formed; according to the construction method, construction of the high-spraying diaphragm wall through the wide-hole-distance double-high-pressure three-pipe method is achieved through the operation method of rotary spraying and swing spraying alternate lifting, in order to guarantee the connection strength during alternate lifting, the lap joint re-spraying mode is adopted, the construction quality and the strength requirement of the diaphragm wall are guaranteed, the construction requirement of the dam diaphragm wall can be fully combined, wide-hole-distance operation is achieved, and the construction efficiency is improved. And the construction efficiency and the construction quality of the diaphragm wall are improved while the normal work of the water delivery hole is not influenced.
本发明提供一种宽孔距双高压三管法高喷防渗墙施工方法，所述防渗墙位于水库坝基，用于对坝基进行防渗加固，为保证水库现有输水洞的正常工作，在马道作业面钻孔时，使钻孔孔距大于输水洞的宽度，形成宽孔距，利用旋喷和摆喷交替提升的作业方法，实现宽孔距双高压三管法高喷防渗墙施工，为保证交替提升时的连接强度，采用搭接复喷的方式，保证防渗墙的施工质量和强度要求，该施工方法可以充分结合大坝防渗墙的施工要求，实现宽孔距作业，在不影响输水洞正常工作的同时，提升防渗墙的施工效率和施工质量。
