[0027] The following is combined with Figure 1 and attached Figure 2 This application is described in further detail.
[0028] The present application embodiment discloses a foundation pit enclosure structure. Figure 1 , including a wall guard plate 100, an upper fixing member 110, a cable 120 and a lower fixing member 130. The wall guard plate 100 is used to fit to the inner wall of the foundation pit 140. The wall guard plate 100 is provided with an upper bending plate 101 that fits to the ground where the foundation pit 140 is located. The wall guard plate 100 is also provided with a lower bending plate 102 that fits to the inner bottom surface of the foundation pit 140. The upper fixing member 110 is passed through the ground where the foundation pit 140 is located and is spaced apart from the upper bending plate 101 in the horizontal direction. The first end of the cable 120 is connected to the upper fixing member 110, and the second end of the cable 120 is connected to the upper bending plate 101. The lower fixing member 130 passes through the lower bending plate 102 and is passed through the inner bottom surface of the foundation pit 140.
[0029] According to a foundation pit retaining structure of the present invention, the wall guard plate 100 is attached to the inner wall of the foundation pit 140, and the upper fixing member 110 and the lower fixing member 130 are respectively penetrated into the ground inside and outside the foundation pit 140. Therefore, the foundation pit retaining structure will not occupy a large area of building area, reducing the impact on the original building.
[0030] Specifically, upper fixing member 110 includes a connecting plate 115 and a first reinforcing cage 116. Connecting plate 115 is attached to the ground surface of foundation pit 140. First reinforcing cage 116 is penetrated into the ground and filled with concrete. Cables 120 are connected to connecting plate 115, and the upper ends of first reinforcing cage 116 are penetrated and fixed to connecting plate 115 by concrete. The configuration of upper fixing member 110 provides a stable structure and effectively secures cables 120 and the baseboard 100 connected thereto.
[0031] Optionally, the lower fixing member 130 includes a second steel cage 131, which passes through the lower bent plate 102 and extends into the inner bottom surface of the foundation pit 140. Concrete is poured into the second steel cage 131. In addition, the second steel cage 131 is fixed to the lower bent plate 102 through the concrete. The provision of the lower fixing member 130 provides a stable structure, effectively fixes the lower bent plate 102 of the baseboard 100, and has a good reinforcement effect on the inner sidewall of the foundation pit 140.
[0032] Further, combined Figure 2 As shown, a fastening bolt 111 is passed through the connecting plate 115, and the fastening bolt 111 is sleeved with the clamping plate 112. The cable 120 is passed between the clamping plate 112 and the top surface of the connecting plate 115. The fastening bolt 111 is loosely fitted with the clamping plate 112 and is threadedly connected to the connecting plate 115. When the fastening bolt 111 is tightened, the cable 120 is fixed between the clamping plate 112 and the connecting plate 115, thereby connecting and fixing the baseboard 100 to the upper fixing member 110.
[0033] Optionally, a plurality of fastening bolts 111 and clamping plates 112 are provided on the upper fixing member 110, and the plurality of fastening bolts 111 and clamping plates 112 are arranged at intervals along the extension direction of the cable 120, so that the connection between the cable 120 and the upper fixing member 110 is more stable.
[0034] Further, refer to Figure 2 The clamping plate 112 has an inner arc surface 113, and the cross-section of the inner arc surface 113 perpendicular to the extension direction of the cable 120 is arc-shaped. The cable 120 abuts against the inner arc surface 113, thereby increasing the connection area between the cable 120 and the clamping plate 112, and enhancing the connection strength between the upper fixed component 110 and the cable 120.
[0035] Furthermore, the inner arc surface 113 of the clamping pressure plate 112 is provided with a plurality of friction ribs 114, which are used to abut against the cable 120, and the plurality of friction ribs 114 are arranged at intervals along the extension direction of the cable 120, thereby enhancing the friction between the inner arc surface 113 and the cable 120, making the connection of the cable 120 more stable.
[0036] Optionally, refer to Figure 1 The baseboard 100 is also provided with reinforcing ribs 103, which are connected to the lower bent plate 102, thereby enhancing the structural strength between the baseboard 100 and the lower bent plate 102. The baseboard 100 is provided with multiple reinforcing ribs 103, which are arranged at intervals along the inner wall of the foundation pit 140. Reinforcing steel bars 104 are welded between adjacent reinforcing ribs 103, thereby further enhancing the structural strength of the baseboard 100.
[0037] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
