Technical Field

[0001] This utility model relates to a water-stop curtain structure, specifically a foundation pit water-stop curtain structure, and belongs to the technical field of foundation pit water-stop curtains. Background Technology

[0002] A cutoff wall is a concept encompassing a series of water-stopping systems around the main structure of an engineering project. It is a continuous water-stopping structure used to prevent or reduce the inflow of groundwater into the foundation pit's sidewalls and bottom. The cutoff wall is installed around the perimeter of the foundation pit to block groundwater seepage, and it requires high stability and strength. Retaining piles are part of the cutoff wall, and their main function is soil retention and support.

[0003] However, when the design depth of the retaining piles is insufficient or the design is unreasonable, they cannot effectively support the stability of the soil and may collapse during the installation of the water-stop curtain. If the retaining piles collapse, the integrity of the water-stop curtain will be affected, which may lead to gaps or failure, thereby affecting the water-stopping effect. Utility Model Content

[0004] The purpose of this utility model is to provide a foundation pit water-stop curtain structure to solve the above problems. The first and second protective plates are installed on the periphery of the retaining piles. The positioning rod can fix the limiting plate in the first and second protective plates, so that the first and second protective plates can block the retaining piles and help prevent the collapse of the surrounding structure of the retaining piles.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: a foundation pit water-stop curtain structure, including retaining piles, with water-stop piles provided around the retaining piles, and a capping beam cast at the top of the retaining piles and water-stop piles. A protective mechanism is installed on the side of the retaining piles away from the water-stop piles. The protective mechanism includes a first protective plate and a second protective plate. The side wall of the retaining piles abuts against the first and second protective plates. The first protective plate has a slot, and the second protective plate is engaged in the slot. Both the first and second protective plates have limiting grooves and insertion holes. A limiting plate is engaged in the limiting groove, and a positioning rod is threaded into the insertion hole. The positioning rod penetrates the inner wall of the limiting plate. The engagement points of the limiting plate with the first and second protective plates are arranged in a T-shape. Supporting mechanisms are fixed on both the first and second protective plates.

[0006] Preferably, the first guard plate and the second guard plate are engaged and connected, and the part of the second guard plate that contacts the first guard plate is set with an inclined structure, and the two slots are symmetrically located at both ends of the first guard plate.

[0007] Preferably, the positioning rod is threadedly connected to the first guard plate and the second guard plate, and is rotatably connected to the limiting plate. The end of the positioning rod near the limiting plate is configured with a regular hexagonal structure.

[0008] Preferably, the limiting plate is located at the connection between the first guard plate and the second guard plate, and the limiting plate is engaged with the first guard plate and the second guard plate.

[0009] Preferably, the support mechanism includes mounting blocks and fixing rods. Mounting blocks are fixedly connected to both the first guard plate and the second guard plate. Fixing rods are fixedly installed between several mounting blocks. Support rods are rotatably connected to the fixing rods. Connecting rods are slidably connected to the support rods. Fixing blocks are rotatably connected to the connecting rods. A chassis is fixedly installed on the fixing blocks. Several insert rods are threaded onto the chassis.

[0010] Preferably, a plurality of the mounting blocks are equidistantly arranged on the sidewalls of the first and second protective plates, and the end of the mounting block facing away from the first and second protective plates is arranged with an arc surface structure.

[0011] Preferably, the two support rods are arranged symmetrically about a mounting block, and the support rods are inclined.

[0012] Preferably, the width of the connecting rod is smaller than the width of the support rod, and the end of the connecting rod is provided with an arc surface structure.

[0013] Preferably, a plurality of the insertion rods are arranged in a ring at equal intervals, and the bottom end of the insertion rod is arranged in an inverted conical structure.

[0014] Preferably, the two fixing blocks are symmetrically arranged about the connecting rod, and the connecting rod is located at the center of the top of the chassis.

[0015] The beneficial effects of this utility model are as follows: A first and second protective plate are installed near the retaining piles in the foundation pit. Since both ends of the first protective plate have slots, the second protective plate can be snapped into these slots, placing it inside the first protective plate. After the first and second protective plates are assembled, a limiting plate can be snapped into the limiting grooves within the first and second protective plates. Because the limiting plate has a T-shaped structure at its contact point with the first and second protective plates, it can connect the first and second protective plates when it is in the limiting groove. The end of a positioning rod penetrates the inner wall of the limiting plate, allowing it to be inserted into the first and second protective plates. Rotating the positioning rod allows its end to be threaded into the first and second protective plates, thus facilitating the blocking of the retaining piles by the first and second protective plates and helping to prevent the collapse of the surrounding structure.
