Adaptive adjustable power wall brushing device and method of underground diaphragm wall joint

Abstract

The invention relates to an adaptive adjustable power wall brushing device and method of an underground diaphragm wall joint. Mounting grooves are symmetrically formed in the two ends of the side portion of a box body of the device; steel wire brush wheels are mounted in the mounting grooves through brush body machine bases; the steel wire brush wheels are connected with driving devices in the brush body machine bases; a channel is formed between the corresponding mounting grooves in the left side and the right side of the box body; a longitudinal adjusting mechanism and a transverse adjusting mechanism of the steel wire brush wheels are arranged in the channel; a fixing sleeve in the longitudinal adjusting mechanism is connected with the transverse adjusting mechanism through a longitudinal sliding guide mechanism; a longitudinal oil cylinder is fixed to the outer side of the box body; a piston rod of the longitudinal oil cylinder is connected with the fixing sleeve; the transverse adjusting mechanism is connected with the brush body machine bases on the left side and the right side. The span of the steel wire brush wheels on the two sides of the box body can be adjusted, the device adapts to brushing of notch joint groove walls with different widths and synchronous brushing of the upper portion, the lower portion, the left portion and the right portion, the brushing efficiency of the underground diaphragm wall joint groove walls is effectively improved, residue of soil and gravel is avoided, and the water stop performance of an underground diaphragm wall is improved.

Description

technical field [0001] The invention relates to an underground diaphragm wall joint construction device, in particular to an underground diaphragm wall joint self-adaptive adjustable power brushing device. Background technique [0002] A present underground diaphragm wall brusher box body, a brush head on one side of the box body, a suspension ring and some stress plates. The wall scrubber does not have telescopic adjustment capability, and can only be used for wall brushing of underground diaphragm wall joints with regular notch rules. In view of the irregular notch of the underground diaphragm wall, the scrubbing capacity of the underground diaphragm wall joint cannot be satisfied. If the joint is scrubbed clean, a large amount of soil and gravel will remain, which will seriously affect the waterproof performance of the underground diaphragm wall and bring immeasurable damage to the subsequent construction. loss.
