For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0018] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0019] A foundation pit support water-stopping device provided in an embodiment, such as Figure 1 , Figure 2 As shown, it includes a water baffle 1, and the water baffle 1 is provided in multiple groups and forms a ring structure. A vertical receiving groove 2 is opened on one side of each water baffle 1, and a water stop plate 3 is slidably installed in the receiving groove 2. A sealing groove 4 matching the water stop plate 3 is opened on the other side of the water baffle 1. The water stop plate 3 on each water baffle 1 is correspondingly embedded in the sealing groove 4 on the adjacent water baffle and is fixed and locked by a positioning mechanism 5. The positioning mechanism 5 is arranged at a position where the receiving groove 2 is opened on the water baffle 1, and a connecting groove 9 connected with the receiving groove 2 is opened on the side wall of the water baffle 1 adjacent to the receiving groove 2. The positioning mechanism 5 includes a control block 501, a connecting rod 502 and an upper limit assembly 503 arranged on the control block 501. The control block 501 is located on the outer wall of the water baffle 1, and the connecting rod 502 is fixed on the side of the water stop plate 3. The end away from the water stop plate 3 passes through the connecting groove 9 and is connected to the control block 501, and a sliding groove 505 connected with the connecting groove 9 and matching in length is opened on the side wall of the water stop plate 3; the limiting assembly 503 is arranged on the control block 501 for positioning the control block 501. When in use, the limiting component 503 positions the control block 501 on the side wall of the water baffle 1. When the gap needs to be sealed, the limiting component 503 releases the restriction on the control block 501 at the side wall of the water baffle 1, and pushes the control block 501 to move on the surface of the water baffle 1. The control block 501 cooperates with the connecting rod 502 to push the water stop plate 3 toward the outside of the storage groove 2 and then insert it into the sealing groove 4.

[0020] like Figure 2 and Figure 3As shown, the limit assembly 503 includes a through hole 5031 provided on the surface of the control block 501, a clamping rod 5032 is slidably installed in the through hole 5031, and a plurality of limit holes 504 are provided on the side wall of the water stop plate 1, which are evenly spaced and cooperate with the clamping rod 5032. The position of the limit hole 504 is staggered with the position of the slide groove 505 and the connection groove. A telescopic groove 5033 is provided on the side wall of the through hole 5031, a sliding block 5034 is fixedly installed on the side wall of the clamping rod 5032, and an extrusion spring 5035 connected to the sliding block 5034 is fixedly installed in the telescopic groove 5033. When in use, the position of the clamping rod 5032 can be conveniently adjusted through the cooperation between the telescopic groove 505 and the sliding block 5034, so that the clamping rod 5032 can be inserted into the clamping holes at different positions, which is convenient for adjusting the position of the water stop plate 3.

[0021] In the initial state of the utility model, the adjusting component 503 cooperates with the connecting rod 502 to fix the water stop plate 3 in the receiving groove 2. When in use, multiple groups of water baffles 1 are installed in sequence around the side wall of the foundation pit, so that the multiple groups of water baffles 1 form a ring structure, and the multiple groups of water baffles 1 are fixed by the surrounding purlin structure. The clamping rod 5032 of the adjusting component 503 is controlled to disengage from the limiting hole 504 on the water stop plate, and the water stop plate 3 is driven to translate to the outside of the receiving groove 2 and inserted into the sealing groove 4 on the surface of another group of water baffles 1. The water stop plate 3 cooperates with the sealing groove 4 to efficiently seal the gap between the two adjacent groups of water baffles 1, effectively improving the outflow of water from the gap between the two groups of water baffles 1; at the insertion port, the clamping rod 5032 is controlled to be inserted into the corresponding limiting hole 504 for locking.

[0022] like Figure 1 , Figure 2 As shown, as a preferred embodiment of the utility model, a control spring 6 connected to the water stop plate 3 is fixedly installed in the storage groove 2. The control spring 6 can buffer the movement process of the water stop plate 3 to maintain its stable movement.

[0023] like Figure 1 , Figure 2 As shown, as a preferred embodiment of the utility model, a limiting groove 7 is provided on one side wall of the baffle plate 1, and the transverse cross-section of the limiting groove 7 is a T-shaped structure. A limiting strip 8 that cooperates with the limiting groove 7 is fixedly installed on the other side wall of the baffle plate 1, which can ensure that the connection between two adjacent baffle plates 1 is tighter.

[0024] The working principle of the utility model is: initially, the water stop plate 3 is completely stored in the storage groove 2 corresponding to the water baffle plate 1, and the clamping rod 5032 of the adjustment component 503 is clamped in the uppermost limiting hole 504 to fix the water stop plate 3 in the storage groove 2. When in use, multiple groups of water baffle plates 1 are sequentially installed around the side wall of the foundation pit, so that the multiple groups of water baffle plates 1 form a ring structure, and the adjacent water baffle plates 1 are first preliminarily connected through the limiting groove 7 and the limiting strip 8, and then the clamping rod 5032 of the adjustment component is disengaged from the corresponding limiting hole 504, and then the control block 501 controls the connecting rod 502 to drive the water stop plate 3 to translate to the outside of the storage groove 2 and insert it into the sealing groove 4 on the surface of another group of water baffle plates 1, and then the clamping rod 5032 is inserted into the corresponding limiting hole at this time to fix it. The water stop plate 3 cooperates with the sealing groove 4 to efficiently seal the gap between two adjacent groups of water baffles 1, thereby effectively improving the outflow of water from the gap between the two groups of water baffles 1.

[0025] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
