Abstract

The invention discloses a self-carrying barrier-breaking and foundation-reinforcing device of a shield machine. The device comprises a cutter, a soil storehouse and other components, wherein the soil storehouse is positioned between the cutter and a cutter driving mechanism, and the cutter driving mechanism is connected with the cutter and controls the cutter to rotate; the soil storehouse, the cutter driving mechanism, a pedestrian bin, a first drilling machine, a second drilling machine, an assembling machine and a screw machine are positioned inside a shield outer shell, wherein the first drilling machine and the second drilling machine are respectively positioned at one side of the screw machine; a frame connecting bridge is fixed at one end of the screw machine, and the assembling machine and the second drilling machine are connected in a rotated way; a thrust cylinder is positioned between the screw machine and the shield outer shell; a spherical hinge is positioned at one side of a connecting bolt; a guide tube, a ball valve, a pipe joint and a control valve group are positioned on the same line, wherein the guide tube and the pipe joint are respectively positioned at two sides of the ball valve, and the pipe joint and the second drilling machine are fixedly connected. The invention ensures that the shield machine propels normally by breaking front barriers and reinforcement is carried out by spraying slurry towards the excavation face in front of the shield and the periphery of the shield.

Description

technical field [0001] The invention relates to the field of shield machines, in particular to a self-portable obstacle breaking and ground reinforcement device for the shield machine. Background technique [0002] With the intensification of the domestic subway network and the increase in the number of tunnels, underground space resources are gradually decreasing, and the location of the tunnels will be restricted by many factors, resulting in various underground obstacles often encountered during shield tunneling construction, such as underground Obsolete and abandoned pipelines, foundation piles, underground diaphragm walls, boulders, etc. The geological conditions where obstacles are located are very diverse, including clay, sand, gravel, soft rock and other geological conditions. [0003] At present, when an underground obstacle is encountered during shield construction, there are mainly two methods for dealing with the obstacle: the method of removing the obstacle and...
