[0024] In the present invention, two adjacent support mechanisms 1 are detachably connected through a quick release mechanism 2. Specifically, a mounting groove 104 is provided on one side of a base 101 of the support mechanism 1, and a through mounting hole 105 is provided on the top of the mounting groove 104. The quick release mechanism 2 includes a housing 201, a group of springs 202 are fixedly installed on the bottom of the inner wall of the housing 201, and a clamping block 203 is fixedly installed on the top of the spring 202.

[0025] Please refer to the attached Figure 1 To Attachment Figure 4 The working principle of the foundation pit reinforcement device for municipal engineering described in the utility model is described in detail.

[0026] When the pit wall needs to be reinforced, the device is transported to the bottom of the pit so that the bottom of the support plate 108 contacts the pit wall, and then the four first threaded rods 103 are rotated and inserted downward into the soil to fix the position of the device. Then the worker can rotate the adjusting wheel 112. When the adjusting wheel 112 rotates, it will drive a second threaded rod 111 to start rotating. When the second threaded rod 111 rotates, the bottom pulley 115 will rotate together. The pulley 115 drives the connecting belt 116 to start moving. When the connecting belt 116 moves, it will drive another pulley 115 and the second threaded rod 111 to rotate together. After the two second threaded rods 111 rotate, they will drive the threaded block 111 connected to the surface thread. 3 rises together, and the threaded block 113 will drive the second ear block 114 and the first rotating shaft 117 to move together during the rising process. The first rotating shaft 117 will make the lever arm 118 with a hole set on the outer wall fixed to move together, and the lever arm 118 with a hole will drive the third ear block 120 to move through the second rotating shaft 119. When the third ear block 120 moves, it will push the support plate 108 to fit closely with the pit wall to reinforce the pit wall. When the reinforcement device is not long enough, the block 203 on one device can be pressed downward, and the block 203 and the shell 201 can be inserted into the installation slot 104 of the other device. At this time, the spring 202 will lift the block 203 to insert it into the inside of the installation hole 105 to connect the two reinforcement devices.
