[0028] The present invention will be described in further detail below with reference to the accompanying drawings.

[0029] like Figure 1 、 Figure 2 As shown, a foundation pit supporting device for construction includes supporting piles 1, a water-stop curtain 2, a crown beam 3, a cross beam 4 and a fixing rod 5.

[0030] like Figure 1 、 Figure 2 As shown, the support piles 1 are arranged on the inner wall of the foundation pit, and the water-stop curtain 2 is arranged in a closed shape around the outer side of the support piles 1, which can prevent water from seeping into the foundation pit, while increasing the structural strength of the ground and preventing the foundation pit from collapsing.

[0031] like Figure 1 、 Figure 2 、 Figure 3 As shown, the crown beam 3 is horizontally positioned between the upper ends of the support piles 1, securing the upper ends of all the support piles 1 together to increase structural strength and stability. A steel cage 11 is positioned within the support piles 1, while a steel frame 31 is positioned within the crown beam 3. The cage 11 and frame 31 are secured together, further increasing their respective strength and the stability of the connection.

[0032] like Figure 1 、 Figure 2 As shown, a guardrail 32 is provided on the crown beam 3, and a water retaining platform 33 is provided at the lower end of the guardrail 32. Therefore, by providing the guardrail 32 with the water retaining platform 33, the safety during the foundation pit construction can be increased, and the water on the ground can be prevented from overflowing into the foundation pit, thereby ensuring stable operation in the foundation pit.

[0033] like Figure 1 、 Figure 2 As shown, the cross beam 4 is arranged on the inner side of the supporting pile 1, and the fixing rod 5 passes through the cross beam 4 and the supporting pile 1 and extends into the interior of the foundation pit. Therefore, by adding the fixing rod 5 and the cross beam 4, the connection and fixation of the supporting pile 1 are achieved, thereby ensuring stable support for the foundation pit.

[0034] like Figure 2 、 Figure 4As shown, the back side of the crossbeam 4 is provided with a clamping strip 41 for clamping the outer wall of the support pile 1. This allows for quick positioning and installation of the crossbeam 4, while also increasing installation convenience and improving construction efficiency. The crossbeam 4 comprises a multi-segment beam 42, one end of which is provided with a plug rod 43, and the other end is provided with a socket 44 for inserting the plug rod 43. Therefore, the segmented crossbeam 4 facilitates both installation and transportation and turnover.

[0035] like Figure 2 、 Figure 5 As shown, a protective plate 6 that fits the inner wall of the foundation pit is provided between two adjacent supporting piles 1, and the crossbeam 4 presses the inner wall of the protective plate 6 to increase the supporting capacity of the inner wall of the foundation pit and avoid collapse between the supporting piles 1.

[0036] like Figure 2 、 Figure 5 As shown, a support rod 61 is horizontally provided on the inner side wall of the protective plate 6. The end of the support rod 61 is threadedly connected to a support tube 62. A pad 63 is provided on the support tube 62 to abut against the crossbeam 4. Therefore, after the protective plate 6 is installed, the support tube 62 can be rotated to adjust the expansion and contraction of the support tube 62, thereby adjusting the pressure exerted by the protective plate 6 on the foundation pit and ensuring stable support of the inner wall of the foundation pit.
