Description
An adjustable waterstop assembly for sheet pile retaining structures Technical Field
[0001] This invention relates to the field of water-stopping technology for underground and underwater engineering retaining structures, and particularly to an adjustable water-stopping component for steel sheet pile retaining structures. Background Technology
[0002] Steel sheet piles are steel structures with interlocking devices on their edges, which can be freely combined to form a continuous and compact retaining wall or water retaining wall.
[0003] Currently, water sealing in sheet pile retaining structures typically relies on the geometric fit of the interlocks and the fixing of water-stopping materials. However, there are still some shortcomings. In actual projects, due to installation deviations, sheet pile deformation, water pressure changes, and vibrations, local gaps are prone to appear at the interlocks, leading to leakage. Most existing water sealing methods cannot provide on-site adjustable compensation for the tightness of the water seal at the interlocks, resulting in the need for repeated grouting or the addition of external water-stopping layers, which is costly and unreliable. The sheet piles also deform and leak after being subjected to stress. Summary of the Invention
[0004] The purpose of this invention is to address the aforementioned shortcomings by providing an adjustable water-stop component for sheet pile retaining structures. This component allows for adjustable tightness of the water-stop at the interlock, compensation for assembly deviations and water pressure variations, improved water-stop reliability, and easier maintenance and replacement. It also prevents deformation at the sheet pile joints and facilitates the installation and disassembly of the support device.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an adjustable water-stop component for a steel sheet pile retaining structure, used to retain multiple interlocking steel sheet piles, comprising: a support plate symmetrically arranged on the steel sheet piles; a water-stop strip disposed on two interlocking steel sheet piles to seal the two interlocking steel sheet piles; multiple water-stop components disposed on the water-stop strips to clamp the water-stop strips to the interlocking steel sheet piles; a pre-embedded column groove disposed opposite the joint of two steel sheet piles; a first mounting component disposed on the water-stop component; a second mounting component disposed on the pre-embedded column groove; and a telescopic component disposed between the first and second mounting components to adjust the telescopic component's support for the steel sheet piles.
[0006] Furthermore, the water-stopping component includes a mounting base and a pressure plate disposed on the water-stopping strip body for clamping it; it also includes a filler block disposed between the mounting base and the pressure plate and a pressure bracket disposed on the pressure plate; it also includes a screw disposed on the mounting base and a nut disposed on the screw for pressing the pressure bracket.
[0007] Furthermore, the pre-embedded column groove is provided with multiple evenly arranged insertion holes.
[0008] Furthermore, the second mounting component includes a movable frame disposed on the pre-embedded column groove and a support plate disposed on the movable frame; it also includes a fixed pipe disposed in the movable frame and an insert rod inserted into the fixed pipe; it also includes a spring disposed on the support plate for sleeved on the insert rod, the insert rod being T-shaped and the end of the spring being fixedly installed to one side of the insert rod.
[0009] Furthermore, the first mounting component and the second mounting component have the same structure.
[0010] Furthermore, the first mounting component is fixedly connected to the mounting base.
[0011] Furthermore, the telescopic member includes a first rotating part disposed on the second mounting member and a driving part disposed on the rotating part; it also includes a telescopic rod disposed on the driving part and a second rotating shaft disposed on the first mounting member, wherein the second rotating shaft is provided with a second rotating block for connecting the telescopic rod.
[0012] Furthermore, the first rotating part includes a first rotating shaft disposed on the second mounting member and a first rotating block disposed on the first rotating shaft.
[0013] Furthermore, the drive unit includes a fixed cylinder disposed on the first rotating block and a rotating column disposed on the fixed cylinder; it also includes a first helical gear disposed on the rotating column and a second helical gear disposed inside the fixed cylinder and meshing with the first helical gear.
[0014] Furthermore, the telescopic rod includes a rotating cylinder disposed inside the fixed cylinder and fixedly installed with the second helical gear, and a stud disposed inside the rotating cylinder and fixedly installed with the second rotating block.
[0015] The beneficial effects of the present invention are as follows: 1. The tightness of the connection between the two steel sheet piles can be adjusted, which can compensate for assembly deviation and stress deformation, adapt to water pressure changes, reduce the probability of leakage, and the structure can be disassembled, making maintenance and replacement convenient.
[0016] 2. In this invention, two sheet piles are sealed together by a water-stop strip. The water-stop strip is clamped by a water-stop component to improve the sealing effect. Then, a pre-embedded column groove is installed on one side of the sheet pile. A second mounting component is installed at different heights on the pre-embedded column groove. A first mounting component is installed on the mounting base side of different water-stop components. A telescopic component drives the first and second rotating parts to rotate. The telescopic component is then adjusted to support the sheet pile. This allows for adjustable tightness of the water-stop at the joint, compensation for assembly deviations and water pressure changes, improved water-stop reliability, and easy maintenance and replacement. It also prevents deformation at the sheet pile joint and facilitates the installation and disassembly of its support device. Attached Figure Description
