Underground Diaphragm Wall Hydraulic Propulsion Scouring Type Wall Brusher

Abstract

The present invention provides a hydraulically propelled scouring type brusher for an underground continuous wall, which includes a brusher body and a driving device. The wall brusher body includes a frame, a first mud pump for spraying fluid behind the frame, a The second mud pump and brush module for flushing the front wall, the driving device is respectively connected with the first mud pump and the second mud pump, the first mud pump and the second mud pump are fixed on the frame, and the brush The module includes a brush body and a support unit, and the brush body is rotatably connected to the frame through the support unit. In the present invention, the first mud pump is used to spray water to generate reverse thrust, so that the brush module of the wall scrubber can be close to the wall; the flushing nozzle of the second mud pump is used to flush the wall; The brush module realizes the cleaning of many different types of wall surfaces, and can effectively clean the dregs and other attachments on the wall surface, thereby improving the connection strength of the joints of the underground diaphragm wall and ensuring the construction quality of the underground diaphragm wall.

Description

Technical field [0001] The invention relates to an underground continuous wall construction equipment, in particular to an underground continuous wall hydraulic propulsion scouring type wall brush. Background technique [0002] The underground continuous wall is a continuous wall constructed below the ground for intercepting water, seepage prevention, and retaining soil. In the concrete construction, the underground continuous wall is divided into a number of fixed length (4-7m) unit trough sections along the length of the wall, which are constructed and connected in sections. After each unit trough section is dug with the trough forming equipment, there are more or less attachments such as muck and soil at the joints between the trough sections. The source of these muck attachments is, on the one hand, the flow of concrete pushing the muck to the joints of the trough during the pouring process; on the other hand, it is left over from the excavation of the trough. In actual con...
