DETAILED DESCRIPTION

[0027] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0028] like Figure 1 , Figure 2 As shown, a foundation pit supporting device includes a base 1, an anchor rod 2, a supporting plate 3, a pair of sliding tubes 4, a pair of sliding rods 5 and a driving mechanism 6.

[0029] like Figure 1 , Figure 2 As shown, the base 1 is horizontally arranged on the ground, and the lower end surface of the base 1 is provided with a plurality of thorn rods 11 that penetrate into the ground, so as to increase the stability of the base 1 on the ground and prevent it from sliding forward and backward. The anchor rod 2 passes through the base 1 and is used to fix the base 1 on the ground.

[0030] like Figure 1 , Figure 2 As shown, the support plate 3 fits the inner wall of the foundation pit to achieve stable support for the inner wall of the foundation pit, a pair of sliding tubes 4 are rotatably connected to the two ends of the base 1 at the lower ends, a pair of sliding rods 5 are slidably connected to the sliding tubes 4, and the upper ends are rotatably connected to the upper and lower outer walls of the support plate 3.

[0031] like Figure 1 , Figure 2 , Figure 3 As shown, the driving mechanism 6 is used to control the sliding movement of the sliding rod 5 , and the driving mechanism 6 includes a driving rod 61 , a driving frame 62 , a screw rod 63 and a hand wheel 64 .

[0032] like Figure 1 , Figure 2 , Figure 3 As shown, the driving rod 61 is horizontally arranged on both sides of the sliding rod 5, and the sliding tube 4 is provided with a driving hole 65 for the driving rod 61 to slide. The driving frame 62 spans the sliding tube 4 and is fixed to the driving rod 61. The screw rod 63 is rotatably connected to the outer wall of the sliding tube 4 and is threadedly connected to the driving frame 62, and the hand wheel 64 is arranged at the end of the screw rod 63.

[0033] When the foundation pit needs to be supported, the base 1 is first fixed to the ground by the anchor rod 2, and then the screw rod 63 is controlled to drive the driving frame 62 to slide, and the driving frame 62 drives the driving rod 61 and the sliding rod 5 to move synchronously to adjust the extension amount of the sliding rod 5, thereby adjusting the tilt angle and the front-back distance of the supporting plate 3. When the supporting plate 3 is pressed against the inner wall of the foundation pit, the inner wall of the foundation pit can be stably supported.

[0034] Therefore, by providing a support plate 3 with an adjustable inclination angle, the inclination of the support plate 3 can be adjusted according to the inclination of the inner wall of the foundation pit, so as to adapt to the inner wall of the foundation pit with different inclinations, meet the support requirements of different foundation pits, and improve the practicality of the entire support device. In addition, during actual use, the extension and contraction amount of the sliding rod 5 can be adjusted to adjust the compression degree of the support plate 3 on the inner wall of the foundation pit, thereby ensuring stable support.

[0035] like Figure 1 , Figure 2 As shown, the back side of the supporting plate 3 is vertically slidably connected to a sliding seat 7, the sliding rod 5 is rotatably connected to the sliding seat 7, and a locking mechanism 8 for fixing the supporting plate 3 is provided on the sliding seat 7.

[0036] like Figure 1 , Figure 2 As shown, the locking mechanism 8 includes a locking rod 81 and a tension spring 82. The locking rod 81 passes through the slide 7, and a row of locking holes 83 for the locking rod 81 to be inserted is provided on the support plate 3. The tension spring 82 is sleeved on the outer wall of the locking tube and fixed between the slide 7 and the rear end of the locking rod 81.

[0037] When the height position of the supporting plate 3 needs to be adjusted, the locking rod 81 is pulled out of the locking hole 83, and then the supporting plate 3 is controlled to slide vertically, and then the locking rod 81 is plugged into the locking hole 83 to fix the supporting plate 3. By providing a supporting plate 3 with adjustable height, the height position of the supporting plate 3 on the inner wall of the foundation pit can be adjusted to meet different support requirements.

[0038] like Figure 1 , Figure 2 As shown, a cavity 31 is provided in the support plate 3, and a plurality of reinforcing rods 32 are staggered in the cavity 31. A plurality of water inlet holes 33 connected to the cavity 31 are provided on the outer wall of the support plate 3, and a drainage pipe 34 is provided on the outer wall of the lower end of the support plate 3.

[0039] When there is water seepage on the inner wall of the foundation pit, the water seeps into the cavity 31 along the water inlet hole 33 and gathers at the position of the drainage pipe 34. Therefore, by setting a support plate 3 that can directionally collect and discharge the water seepage on the inner wall of the foundation pit, the water is prevented from entering the foundation pit, thereby ensuring the smooth progress of the construction in the foundation pit.

[0040] like Figure 1 , Figure 2As shown, the upper end of the support plate 3 is bent outward to be provided with a protective plate 35, and the protective plate 35 is used to pass over the top of the foundation pit. Therefore, when rainwater overflows over the foundation pit, the protective plate 35 can block the rainwater on the ground and prevent the rainwater from entering the inside of the foundation pit.

[0041] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
