Underground diaphragm wall joint surface brushing method
The invention belongs to the technical field of underground diaphragm walls, discloses a method for brushing joint surfaces of underground diaphragm walls, and solves the problem that replacement of a gripper and a brush head on a grooving machine takes a long time. The method comprises the steps that (1) a wall brushing mechanism is placed at the joint position of the underground diaphragm wall; (2) a steel wire brush on the wall brushing mechanism is used for cleaning the joint position of the underground diaphragm wall; when the rotating speed of the steel wire brush is reduced and the torque is increased, the wall brushing mechanism controls the steel wire brush to repeatedly lift and descend for a certain distance for local brushing; and if the rotating speed of the steel wire brush is still reduced compared with the speed during normal operation and the torque is still increased compared with the torque during normal operation after local brushing of the steel wire brush, the cleaning cutter teeth on the wall brushing mechanism extend out to jointly perform brushing until the rotating speed and the torque return to normal. The device can be used independently, so that the grabbing head and the brush head do not need to be replaced on the grooving machine, the preparation time for cleaning and brushing the groove wall is greatly shortened, and the cleaning and brushing efficiency of the groove wall is improved.
本发明属于地下连续墙技术领域，公开了一种地下连续墙接头面清刷方法，在成槽机上更换抓头和刷头花费时间长的问题。本发明包括：(1)在地下连续墙接头位置处放置刷壁机构；(2)利用刷壁机构上的钢丝刷对地下连续墙接头位置进行清理；当钢丝刷的转动速度降低并且扭矩增大时，刷壁机构控制钢丝刷反复上提、下降一定距离进行局部清刷；若钢丝刷进行局部清刷后，钢丝刷的转速相比正常运行时速度仍然降低、并且扭矩相比正常运行时的扭矩仍然增大时，则刷壁机构上的清理刀齿延伸出来共同进行清刷直至转速和扭矩恢复正常。本发明能够独立使用，因此不需要在成槽机上更换抓头和刷头，从而大大降低清刷槽壁的准备时间，提高槽壁清刷的效率。
