Hydraulic double-wheel milling deep mixer

Abstract

The invention discloses a hydraulic double-wheel milling deep mixer and belongs to the technical field of underground diaphragm wall construction. The hydraulic double-wheel milling deep mixer comprises a mounting rod, mud feeding pipelines and air supply pipelines. A mounting mechanism is mounted at the bottom of the mounting rod, rotating shafts are arranged in the inner cavities of the left andright ends of the bottom of the mounting mechanism. A motor rack is mounted on the surface of a rotating shaft of a hydraulic motor, a transmission gear is mounted in the inner cavity of the mountingmechanism through a mounting shaft, the surface of the transmission gear and the surface of the motor gear are buckled, and chains are mounted on the surface of the motor gear and the surface of thetransmission gear. The mud feeding pipelines and the air supply pipelines on the surface of the motor gear are all arranged in the inner cavity of the mounting rod, and the two mud feeding pipelines of the same structure penetrate through the inner cavity of the mounting mechanism. According to the hydraulic double-wheel milling deep mixer, walls of different widths are mixed and machined conveniently, and at the same time, the quality of machining is ensured.

Description

technical field [0001] The invention relates to the technical field of underground continuous wall construction, in particular to a hydraulic double-wheel milling deep mixer. Background technique [0002] At present, the application of foundation and vertical anti-seepage treatment construction is nothing more than concrete, cement soil and grouting treatment technology, mainly adopting construction technologies such as hydraulic grab bucket forming wall, multi-head small-diameter deep-layer mixing pile-ground connecting wall, and trenching forming wall. The wall forming of the grab groove machine is to build a guide wall on the ground of the proposed underground continuous wall, and the hydraulic grab excavates along the guide wall, and the verticality of the grab is measured by an inclinometer. Then the deviation is corrected by operating the hydraulic push plate Adjust the vertical condition of the hydraulic grab to control the accuracy of groove formation. Use mud to pr...

Problems solved by technology

After the trough is formed, the floating soil at the bottom of the trough is removed through the hole cleaning process to improve the bearing capacity of the wall; finally, the reinforcement cage is put in for underwater concrete pouring. However, the traditional milling device can only be used for grooves of fixed width. processing, and in real life, buildings with different requirements have different requirements for the thickness of the wall. When the traditional milling device processes the wall with increased thickness, it can only be realized by secondary processing or moving the reloading vehicle. The efficiency is very slow, and the quality of the wall is difficult to guarantee
