Milling wheel scrubbers for underground diaphragm wall snap fittings

Abstract

The invention discloses a milling wheel wall brushing device for an underground diaphragm wall lock catch pipe connector. The milling wheel wall brushing device comprises a hydraulic grab trenching machine body and further comprises a movable shaft, a milling wheel machine and a hydraulic jack, wherein hydraulic push rods are arranged on the two sides of the hydraulic grab trenching machine body, and the hydraulic push rods can be driven by hydraulic power to ascend or descend; one end of the movable shaft is hinged to the hydraulic push rods; the milling wheel machine is connected with the other end of the movable shaft; and a shell of the hydraulic jack is hinged to the hydraulic push rods, a connecting rod of the hydraulic jack is hinged to the middle portion of the movable shaft, and the hydraulic jack communicates with an oil path of the hydraulic grab trenching machine body through a first electromagnetic valve. The milling wheel machine comprises a hydraulic drive motor, a milling wheel and a plurality of milling cutters, wherein a shell is fixed to the other end of the movable shaft, and the hydraulic drive motor communicates with an oil path of the hydraulic grab trenching machine body through a pipeline and a second electromagnetic valve; a center shaft of the milling wheel is fixed to a rotating shaft of the hydraulic drive motor; and the multiple milling cutters are arranged on the circumferential face of the milling wheel. The milling wheel wall brushing device has the beneficial effects that one machine has double purposes, the wall brushing effect is good, and water leakage is prevented.

Description

technical field [0001] The invention relates to the field of building foundation construction, in particular to a wall milling wheel brusher used for locking pipe joints of underground continuous walls. Background technique [0002] The underground diaphragm wall is a relatively advanced underground engineering structure and construction technology. In the case of mud retaining wall, a long and narrow deep groove is excavated, a steel cage is placed in the groove, and underwater concrete is poured to form a section of reinforced concrete. Wall section, connecting several wall sections into a whole to form a continuous underground wall, which is used for underground water interception and seepage prevention or soil retaining and load bearing. The joints between underground diaphragm wall sections include locking pipe joints, cross steel plate joints, prefabricated concrete joints, etc. Among them, the joints with the simplest form and the lowest cost are locking pipe joints. ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems that the traditional wall brushing technology used for locking pipe joints, that is, the steel wire brushing effect is poor, and even the wall brushing meets the quality requirements, the water-stopping effect is still not ideal, etc., and the invention provides a lock for underground continuous walls. The milling wheel wall brusher with buckle pipe joint, the milling wheel wall brusher obtains power through the switching of the hydraulic grab oil supply pipeline through the solenoid valve, and the rotation of the milling wheel drives the milling cutter to chisel the concrete at the joint, with strong chiseling ability and good wall brushing effect. In addition, it is possible to chisel the entire section of the joints of the underground diaphragm wall, and the joints of the underground diaphragm wall are W-shaped after chiseling, thereby effectively solving the problem of water leakage in the form of locking pipe joints of the underground diaphragm wall, and effectively reducing the blockage of the joints of the underground diaphragm wall in the later stage. leakage cost
