[0021] Example

[0022] The technical solutions in the embodiments of the present utility model will be described clearly and completely below in conjunction with the accompanying drawings.

[0023] like Figure 1-4 As shown, a fast-constructed assembled foundation pit system structure includes a foundation pit retaining structure, which includes a retaining plate 1 and a fixing plate 2. The retaining plate 1 is arranged on the side of the foundation pit and fits with it. The fixing plate 2 is arranged at the bottom of the foundation pit. The retaining plate 1 and the fixing plate 2 are connected by a connecting structure. A lifting ring 16 is arranged on the top of the retaining plate 1 to facilitate the transportation of the retaining plate 1. Both sides of the retaining plate 1 are respectively provided with mounting grooves 3 and mounting protrusions 4. Adjacent retaining plates 1 are connected by mounting grooves 3 and mounting protrusions 4, so that Adjacent enclosure panels 1 rely on each other, and a stepped through hole 5 is provided on the enclosure panel 1 to fix the enclosure panel 1 on the side wall of the foundation pit. A first clamping groove 6 and a second clamping groove 7 are respectively provided on the enclosure panel 1 and the fixing plate 2. The first clamping groove 6 and the second clamping groove 7 are installed with the same clamping block 1 8 and the clamping block 2 9. The clamping block 1 8 is in a triangular shape, or a hollow triangular shape, and any shape that can achieve the support purpose is acceptable. The clamping block 2 9 is an inverted trapezoidal structure plus a rectangular parallelepiped structure, which limits and fixes the clamping block 1 8.

[0024] The connection structure includes a lap plate 10 arranged at one side of the bottom of the enclosure plate 1, and a first mounting block 11 and a second mounting block 12 are respectively arranged on both sides of the bottom of the lap plate 10. A clamping plate 13 is arranged at the bottom of the fixed plate 2 near the second clamping groove 7, and the clamping plate 13 is clamped between the first mounting block 11 and the second mounting block 12, and the clamping plate 13, the first mounting block 11 and the second mounting block 12 are rotatably connected through a connecting shaft 14. The first mounting block 11, the second mounting block 12 and the clamping plate 13 are all provided with mounting holes 15 for the insertion of the connecting shaft 14.
