Abstract

The invention discloses a continuous wall milling machine, which comprises a host machine base plate, an upright post, a gantry frame, a guide frame, a milling box, a milling and stirring chain, a steel wire rope, an inclined strut and a correcting mechanism, wherein a milling frame adopts a box structure and can be extended to a set length; the milling and stirring chain comprises a chain, and multiple groups of crossed milling cutter bodies and multiple groups of stirring bodies which are fixedly arranged on the chain at certain intervals; after the chain is arranged on a driving chain wheel and a driven chain wheel, a chain transmission mechanism is formed; a transmission case is positioned on the upper part of the milling box; a driving head is fixedly arranged at an installation position above the transmission case; the driving chain wheel is arranged on an output shaft at the lower end of the transmission case; the output shaft is arranged on a supporting platform; one end of a tension oil cylinder is hinged with the lower part of the supporting platform, and the other end of the tension oil cylinder is connected with a lower rod piece; the correcting mechanism is used for obliquely correcting the front, back, left and right of the milling frame; multiple groups of grout pipes are arranged inside the milling frame along the length direction of the milling frame; and the end parts of the grout pipes are provided with spray heads. The continuous wall milling machine is suitable for underground facilities of large buildings, deep foundation excavation and cut-off wall construction of water conservancy dams.

Description

Technical field

[0001] The invention relates to a continuous wall milling machine for drilling formations and constructing underground continuous walls of equal thickness in underground deep foundation engineering. Background technique

[0002] At present, in the construction of underground facilities of large buildings, deep foundation excavation and anti-seepage walls of water conservancy dams, two technologies of multi-axis diaphragm wall drilling machine and underground continuous excavator are generally used for the construction of underground diaphragm wall.

[0003] Multi-axis diaphragm wall drilling machine is used to construct column-type underground diaphragm wall, which is the widely used SMW construction method at present. Multi-axis diaphragm wall drilling machine is used to continuously drill, mix and lift, and mix soil and cement slurry in situ. Each construction unit is overlapped and drilled and excavated repeatedly to build an underground retaining and wate...
