The present invention will be further described below in conjunction with the accompanying drawings.

[0019] like Figure 1-4 As shown, the utility model proposes a water-stop retaining structure for a foundation pit of a building on a soft soil foundation, comprising a foundation pile 1 and a baffle plate 2. The foundation pile 1 is rammed deep into the soft soil, and the baffle plate 2 is detachably fixed on the foundation pile 1. The bottom end of the baffle plate is pressed on the soft soil. The foundation pile 1 and the baffle plate 2 are each provided with a plurality of groups, and the foundation pit is enclosed by a plurality of the foundation piles 1 and the baffle plate 2. Clay 3 is smeared on the side wall of the baffle plate 2 close to the foundation pit, and a connecting piece 4 is provided between the baffle plate and the foundation pile 1. By ramming the foundation pile 1 deep into the ground, the baffle plate 2 is fixed on the foundation pile 1 to increase the stability of the baffle plate 2, and then combined with the clay 3 to improve the water-retaining property of the baffle plate 2.

[0020] like Figure 2 As shown, the connecting member 4 includes a ferrule 5, which is sleeved on the foundation pile 1, and the side wall of the ferrule 5 is provided with a connecting column 6, and the side wall of the enclosure plate 2 is provided on the connecting column 6.

[0021] like Figure 2 As shown, the clamping sleeve 5 is arranged in a C-shaped structure, and the clamping sleeve 5 is elastic. The side walls at both ends of the clamping sleeve 5 are provided with fixing plates 7, and the fixing plates 7 are provided with through-holes 8. The through-holes 8 pass through fastening bolts 9, and the fastening bolts 9 are threadedly connected with nuts 10. The two fixing plates 7 can be pressed together by the nuts 10, so that the clamping sleeve 5 can be tightened. The clamping sleeve 5 is clamped on the foundation pile 1 to fix the enclosure plate 2.
