Description

Technical Field

[0001] This utility model belongs to the field of waterfront structure engineering technology, and in particular relates to a gate for vertical water-stopping in straight-wall waterfront structures. Background Technology

[0002] Water-adjacent structures are widely used in construction cofferdams, docks, and other engineering fields. By utilizing the water-blocking function of the structure, they form an enclosed space, creating conditions for dry construction, improving construction efficiency, and saving construction time.

[0003] Straight-wall structures are common waterfront structures, saving on sea area and water-crossing area compared to conventional sloping earth-rock cofferdams. Common straight-wall structures include slab structures and gravity structures. Water-stopping technology for flush-arranged gravity structures is relatively mature. Generally, horizontal steel gates with waterstops are installed at both ends of the gravity structures, pre-tensioned in both directions. Water is then pumped into the cavity between the gates, creating a head difference that forces the waterstops on the horizontal gates to press firmly against the gravity structure surfaces on both sides, achieving a water-stopping seal. However, existing horizontal steel gates are not suitable for gravity structures that are not flush-arranged or have right-angle bends. Therefore, it is necessary to research a water-stop gate suitable for use between gravity structures that are not flush-arranged or have right-angle bends to solve the problem of vertical right-angle water-stopping. Utility Model Content

[0004] The purpose of this utility model is to provide a gate for vertical water-stopping in straight-walled water-adjacent structures. It has a simple structure, is easy to manufacture, and can be used between gravity structures that are not flush and have right-angle bends, thus solving the problem of vertical right-angle water-stopping.

[0005] This utility model is achieved through the following technical solution:

[0006] A gate for vertical water-stopping in a straight-walled water-adjacent structure includes a gate body and a bottom sealing steel plate disposed at the bottom of the gate body. The gate body includes three main steel plates connected in sequence, with an obtuse angle between two adjacent main steel plates. Multiple reinforcing ribs are provided between the three main steel plates, and the multiple reinforcing ribs are spaced apart along the length direction of the main steel plates.

[0007] Furthermore, several steel pull rings are provided on the side of the main steel plate located in the middle that is away from the reinforcing ribs.

[0008] Furthermore, the outer surfaces of the main steel plate, reinforcing ribs, and bottom sealing steel plate are coated with an anti-corrosion coating.

[0009] Furthermore, the anti-corrosion coating includes a primer layer, a middle layer and a topcoat layer from the inside out. The primer layer is a zinc-rich primer, the middle layer is a polyurethane paint, an epoxy resin paint or a chlorinated rubber paint, and the topcoat layer is a thick-film epoxy paint, a chlorinated rubber paint or a polyurethane paint.

[0010] Furthermore, the dry film thickness of the primer layer is not less than 75 μm, the dry film thickness of the intermediate coat layer is not less than 200 μm, and the dry film thickness of the topcoat layer is not less than 100 μm.

[0011] Furthermore, the thickness of the main steel plate, reinforcing ribs, and bottom sealing steel plate is 10–20 mm.

[0012] Compared with existing technologies, the advantages of this utility model are: simple structure and easy to manufacture. The gate structure is designed as a three-sided main steel plate and reinforcing rib plate. It makes full use of the structural effect by utilizing mechanical principles, reducing stress concentration, and making the force more reasonable. The vertical pressure on the middle side can be decomposed into vertical forces in two directions. Under the action of water pressure, it is conducive to the main steel plate to better fit the concrete structure surface of the gravity structure, so as to achieve the effect of water-stopping and sealing. It economically and reasonably solves the problem of right-angle water-stopping between non-flush straight wall structures. Attached Figure Description

Figure 3 This is an elevation view of the gate for vertical water-stopping in a straight-walled water-adjacent structure according to the present invention. A gate for vertical water-stopping in a straight-walled water-adjacent structure includes a gate body and a bottom sealing steel plate 3 disposed at the bottom of the gate body. The gate body includes three main steel plates 1 connected in sequence, with an obtuse angle between two adjacent main steel plates 1. Multiple reinforcing ribs 2 are provided between the three main steel plates 1, and the multiple reinforcing ribs 2 are spaced apart along the length direction of the main steel plates 1.

[0026] Three main steel plates 1 form a trapezoidal structure resembling a bottomless shape. The specific side lengths and angles can be determined based on the water-retaining width through component strength calculations. Reinforcing ribs 2 are horizontally positioned between the three main steel plates 1 and connected to them respectively, providing load-bearing support, increasing rigidity, and controlling overall structural deformation. The spacing between the reinforcing ribs 2 can be varied based on the design head difference and structural strength calculations. A bottom sealing steel plate 3 is installed at the bottom for bottom water sealing. The gate is welded from steel plates of different specifications; the thickness of the selected steel plates is determined based on the design head difference through component strength calculations. In one embodiment, the thickness of the main steel plate 1, reinforcing ribs 2, and bottom sealing steel plate 3 is 10–20 mm.

Figure 5This is a schematic elevation view of the gate used for vertical water-stopping in a straight-walled water-adjacent structure according to this utility model. During underwater installation, the gate for vertical water-stopping in a straight-walled water-adjacent structure is positioned with the assistance of steel wire ropes and a winch, and pre-tensioned. The main steel plates 1 on both sides are attached to the gravity structures 6 on both sides via vertical water-stop strips 7, providing initial water-stopping effect. Similarly, the bottom sealing steel plate 3 is pressed against the concrete base plate by the bottom water-stop strip 8 under gravity, achieving bottom water-stopping. In one embodiment, several steel pull rings 4 are provided on the side of the main steel plate 1 located in the middle away from the reinforcing rib 2. The steel pull rings 4 are used to assist in the underwater installation and positioning of the gate. Further, the number of steel pull rings 4 is set to two, and the height of the steel pull rings 4 needs to be set according to water depth conditions, winch position, etc.
