External wall brushing device and grooving method for ultra-deep underground diaphragm wall of high-permeability stratum
The invention relates to an externally-hung wall brushing device and a grooving method for a high-permeability stratum ultra-deep underground diaphragm wall, the externally-hung wall brushing device is installed on the outer side of a grab bucket through an upper fixing part and a lower fixing part, and the externally-hung wall brushing device is sequentially provided with a scraping strip fixing plate, a brushing plate and a fixing plate from top to bottom. Comprising the steps that a guide wall is constructed, a rock surface is surveyed, and the design depth of each unit groove section is determined; a three-grabbing method is adopted to excavate the unit groove sections; the externally-hung wall brushing devices are installed on the two sides of the grab bucket to brush the wall face. The grab bucket has the beneficial effects that the unit groove sections are excavated by adopting a three-grabbing method, so that the grab bucket is balanced in stress; the field underground diaphragm wall construction depth is actually determined, work efficiency waste caused by unified depth design is avoided, and the construction efficiency is further improved; the external wall brushing device which can be mounted on one side or two sides of the grab bucket is designed, can be independently used for wall brushing construction and can also be synchronously used during grooving.
本发明涉及一种外挂式刷壁器及高透水性地层超深地下连续墙成槽方法，外挂式刷壁器，通过上部固定和下部固定安装在抓斗外侧，从上到下依次设有刮条固定板、刷板和固定板。包括步骤：施工导墙，对岩面进行勘察，确定每个单元槽段的设计深度；采用三抓法对单元槽段进行开挖；将外挂式刷壁器安装在抓斗的两侧，对壁面进行清刷。本发明的有益效果是：采用三抓法对单元槽段进行开挖，使抓斗吃力均衡；实际确定现场地下连续墙施工深度，避免统一深度设计造成的工效浪费，进一步提升了施工效率；设计了一种可以安装在抓斗单侧或两侧的外挂式刷壁器，不仅可以单独用于刷壁施工，还可以在进行成槽时同步使用。
