Abstract

A double-wheel milling and stirring device for foundation treatment and vertical anti-seepage treatment relates to pile foundation construction equipment and construction method. , There is a milling connecting rod on the lower side of the guide mounting frame, a hydraulic oil pipe, a grouting pipe and an air pipe are arranged on the milling connecting rod, and a mounting seat is arranged at the lower end of the milling connecting rod, and the left swing arm and the right swing arm are hinged on the mounting seat. The mounting seat is provided with a swing arm drive device, and the lower ends of the left swing arm and the right swing arm are respectively provided with a left hydraulic drive device, a left milling stirring wheel, a right hydraulic driving device, and a right milling stirring wheel; left milling stirring wheel and right milling stirring wheel Under the driving control of the swing arm driving device, the wheel spacing of the left milling stirring wheel and the right milling stirring wheel can be adjusted; the lower ends of the hydraulic oil pipes are respectively connected with the left hydraulic driving device and the right hydraulic driving device. The invention has the advantages of simple structure, low cost, high work efficiency, reliable work and the like.

Description

technical field [0001] The invention relates to a pile foundation construction equipment and a construction method, in particular to a double-wheel milling and stirring device and a construction method for foundation treatment and vertical anti-seepage treatment. Background technique [0002] At present, in the foundation treatment and vertical anti-seepage treatment methods in China, the SMW construction method, the diaphragm wall grab, and the TRD construction method have been widely used in recent years. Hydraulic milling and mixing cement soil connecting wall (HCSCMW method) is a world-recognized advanced waterproof and seepage-proof continuous wall. However, both hydraulic milling, multi-axis mixing and diaphragm wall grabs have a common problem, that is, in order to avoid offset caused by unilateral force, the construction sequence is completed by jumping. Although the TRD construction method solves the above problems, it has the problem of high cost and low efficienc...
