[0027] During construction, it is necessary to dig a foundation pit to ensure that the construction work of the building can proceed smoothly. The foundation pit is a soil pit excavated at the foundation design position according to the base elevation and foundation plane size. However, the traditional foundation pit has a poor earthquake resistance. If it encounters a sudden vibration caused by external force, it cannot reduce the vibration force, which will affect the foundation pit, reduce its stability, and cause unnecessary resource loss.

[0031] Working principle: In the process of building construction, it is necessary to dig a foundation pit to ensure that the construction work of the building can proceed smoothly. The foundation pit is a soil pit excavated at the foundation design position according to the base elevation and foundation plane size. However, the traditional foundation pit has a poor earthquake resistance. If it encounters a sudden vibration caused by external force, it cannot reduce the vibration force, which will affect the foundation pit, reduce its stability, and cause unnecessary resource loss. The present application acts through a reinforcement device, and applies an action force to the reinforcement plate 402, so that the action block 401 is stuck in the action groove 3, and the action block 401 is stuck in the action groove 3. The structural plate 410 is inserted into the interior of the positioning slide hole 408. After the bottom of the structural plate 410 is fixed in the interior of the positioning groove 409, the folding plate 411 is fixed to the inner walls of the four corners of the reinforcement cavity 403. Then, the connecting block 406 is used to clamp the clamping block 405 in the interior of the clamping groove 404, so that the U-shaped plate 407 is fixed on the reinforcement plate 402, and the soil is filled near the U-shaped plate 407. The fixing block 413 is inserted into the interior of the fixing groove 412, so that the fixing frame 414 is fixed in the interior of the reinforcement cavity 403. When encountering external force vibration, the vibration force is transmitted to the U-shaped plate 407. The U-shaped plate 407 vibrates in the soil and initially reduces the vibration force. After the vibration force is transmitted to the reinforcement cavity 403, the structural plate 410 and the folding plate 411 cooperate to avoid deformation of the reinforcement plate 402 during the vibration process, and under the action of the shock-absorbing rubber pad 415, the vibration force is further weakened, so that the force transmitted to the fixed frame 414 is further reduced, thereby achieving a mitigation effect on the vibration force, ensuring the stability of the foundation pit, and reducing unnecessary resource losses. In addition, after the foundation pit reinforcement is completed, subsequent construction work is required. During the construction work, There is a phenomenon that nearby soil and rocks enter the foundation pit, affecting the subsequent operations. In order to ensure the smooth progress of the construction work, the protective device is used. By inserting the insertion rod 501 into the enclosed cavity of the folding plate 411 and turning on the small motor 507 on the lower protective plate 502 according to the construction site conditions, the central axis 508 inside the lifting cavity 503 drives the gear 509 to rotate. With the cooperation of the gear teeth 506 of the structural groove 505, the upper protective plate 504 drives the slider 511 to move along the direction of the slide groove 510, thereby realizing the adjustment of the size of the protective device and achieving the protective effect during the construction process.
