A switch 320 connected to the lighting tube 310 through an electric wire is provided at one end of the lamp holder 300.

[0034] The edge of one end of the corrugated plate 100 away from the corrugated extrusion plate 110 is hinged with six movable sleeves 190 arranged at intervals along the height direction of the corrugated plate 100. The movable sleeves 190 can rotate along the length direction of the corrugated plate 100 to be parallel or perpendicular to the corrugated plate 100. Each movable sleeve 190 is provided with a claw 200 that can move along it. A telescopic spring 210 is connected between the claw 200 and the inner wall of the movable sleeve 190. The other end of the corrugated plate 100 away from the corrugated extrusion plate 110 is hinged with six movable sleeves 190 arranged at intervals along the height direction of the corrugated plate 100. The movable sleeves 190 can rotate along the length direction of the corrugated plate 100 to be parallel or perpendicular to the corrugated plate 100. Each movable sleeve 190 is provided with a claw 200 that can move along it. A telescopic spring 210 is connected between the claw 200 and the inner wall of the movable sleeve 190.

A magnet 340 corresponding to the movable sleeve 190 is also provided on the side of the corrugated plate 100 away from the corrugated extrusion plate 110, and the magnet 340 is provided on the side of the corresponding movable sleeve 190 facing the corresponding fixed block 220, and the movable sleeve 190 is made of magnetic stainless steel material. When the movable sleeve 190 is rotated inward along the length direction of the corrugated plate 100 to be parallel to the corrugated plate 100, it is magnetically adsorbed to the corresponding magnet 340.

[0035] When installing the recyclable foundation pit support retaining wall provided in the embodiment of the present application, the operator carries the corrugated plate 100 and the corrugated extruded plate 110 to the foundation pit by holding the corrugated plate 100 away from the hand-held handle 290 provided on one side of the corrugated extruded plate 110, and fits the corrugated extruded plate 110 against the inner wall of the foundation pit, so that the base 160 at the bottom of the corrugated plate 100 is pressed against the ground, and the ground-inserting fixing cone 330 and the tooth plate 350 provided at the bottom of the base 160 are respectively inserted into the position of the fixing base 160 in the ground, and then the fixing handle 280 connected to the top of the fixing screw 270 can be rotated to drive the fixing screw 270 to rotate, so that the fixing screw 270 moves axially along the corresponding fixing hole 250 when rotating to pass through the fixing hole 250 and insert into the stable fixing base 160 on the ground, and then the adjacent recyclable foundation pit support retaining walls are installed in the same way, so that the ends of each recyclable foundation pit support retaining wall are butted, and the The connecting columns 170 and the card slots 180 respectively provided on the end faces of the base 160 of the recyclable foundation pit supporting retaining wall are respectively engaged with the corresponding card slots 180 and the connecting columns 170 at the two ends of the base 160 of two adjacent recyclable foundation pit supporting retaining walls. At the same time, the claws 200 of each movable sleeve 190 of the recyclable foundation pit supporting retaining wall are moved to stretch the corresponding telescopic springs 210, and then the respective movable sleeves 190 and the claws 200 of the recyclable foundation pit supporting retaining wall are rotated outward along the length direction of the corrugated plate 100 to be parallel to the corrugated plate 100 and then released so that the telescopic springs 210 drive the claws 200 to contract and insert into the sockets 230 on the corresponding fixed blocks 220 of another recyclable foundation pit supporting retaining wall, so that the two adjacent recyclable foundation pit supporting retaining walls are stably connected into a whole, thereby increasing the sealing between the two adjacent recyclable foundation pit supporting retaining walls. At the same time, the corrugated plate 100 and the corrugated extruded plate 110 are connected to form a foundation pit support retaining wall. The two layers of corrugated plates can be used to improve the overall structural strength and toughness, which is beneficial to improving the support effect.

[0036] Among them, a lamp holder 300 is connected to the top of the corrugated plate 100, and a lighting tube 310 is provided on the lamp holder 300. A switch 320 connected to the lighting tube 310 by an electric wire is provided at one end of the lamp holder 300. The operator can use the switch 320 to control the lighting tube 310 to turn on for lighting, so as to provide lighting at night and serve as a warning; at the same time, the operator can turn the hand wheel 140 to drive the threaded rod 130 to rotate and move axially to drive the corrugated extrusion plate 110 to press against the pit wall for continuous extrusion, so that excess moisture in the soil of the pit wall can be squeezed out, and the squeezed water can be discharged through the leakage hole 240 on the corrugated extrusion plate 110. By arranging a guide sleeve 360 ​​on the corrugated extrusion plate 110, and arranging a guide rod 150 passing through the guide sleeve 360 ​​and connected to the corrugated extrusion plate 110, a guiding and limiting role can be played when the corrugated extrusion plate 110 moves.

[0037] When the reusable foundation pit support retaining wall is not in use but is stored and moved, each movable sleeve 190 can be rotated inward along the length direction of the corrugated plate 100 to be parallel to the corrugated plate 100, so that each movable sleeve 190 is magnetically adsorbed to the corresponding magnet 340 for fixation, so as to avoid the movable sleeve 190 from rotating arbitrarily in an unfixed and movable state, causing personal injury or equipment damage.

[0038] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.
