A water-retaining device for river construction

Abstract

This utility model provides a water-blocking device for river construction, including a cutting assembly. The cutting assembly includes multiple cutting rods, with a blocking cable between the cutting rods. Multiple first baffles are provided on the blocking cable, and second baffles are provided between the first baffles. Each first baffle includes a first vertical plate, with a vertical first flat plate on one side. Each second baffle includes a second vertical plate, with a vertical second flat plate on one side. This device, by being pre-installed upstream of the cofferdam, can effectively block and disperse the kinetic energy of the upstream water flow, significantly reducing the impact of the water flow on the downstream initial cofferdam. The combination of the first and second baffles and the blocking cable forms a multi-layer buffer. With the help of adjustable sliding seats and rubber convex plates, it can adapt to the elevation difference of the river channel, improve the water-blocking sealing performance, and further enhance the structural stability by filling the inclined support plates with sand and gravel to increase the counterweight, reduce its own displacement, reduce the frequency of repairs, shorten the construction cycle, and at the same time reduce the disturbance to the river water environment.

Description

Technical Field

[0001] This utility model relates to the field of river construction, and in particular to a water-blocking device used in river construction. Background Technology

[0002] In the construction of water conservancy projects such as river regulation and bridge foundations, it is often necessary to set up cofferdams in the river to create a dry working environment. In traditional construction, the initial cofferdams are mostly constructed by stacking sandbags and filling earthen dikes. However, their resistance to water flow impact is weak. Because the river water has continuous kinetic energy, especially during the flood season or in sections with rapid water flow, the initial cofferdams are directly eroded by the water flow, which can easily lead to problems such as dike collapse and foundation scouring, resulting in serious soil erosion. This not only requires repeated repairs of the cofferdams, increasing construction costs and time, but may also cause river siltation due to soil erosion.

[0003] Existing water-retaining devices are mostly designed for reinforcing existing cofferdams, and lack upstream buffer facilities that can be pre-installed in the early stages of construction. Therefore, there is an urgent need for a water-retaining structure that can be installed before the initial construction of the cofferdam. By weakening the energy of the upstream water flow in advance, the direct impact of the water flow on the initial cofferdam can be reduced, thereby reducing soil erosion from the source and ensuring construction efficiency and safety. Utility Model Content

[0034] The first baffle 2 includes a first vertical plate 201, and a vertical first flat plate 202 is provided on one side of the first vertical plate 201;

[0035] The second baffle 3 includes a second vertical plate 301, and a vertical second flat plate 302 is provided on one side of the second vertical plate 301.

[0036] In the preferred embodiment, a tensioning tube 102 is provided through one side of the insertion rod 101, and a tightening seat 106 is provided at one end of the barrier cable 103 that passes through the tensioning tube 102.

[0037] The tensioning seat 106 is threaded to the outer diameter of the tensioning tube 102, and the tensioning seat 106 is used to tighten the arresting cable 103.

[0038] In the preferred embodiment, a first diagonal brace 203 is provided between the first vertical plate 201 and the first flat plate 202. The first diagonal brace 203 is used to reinforce the connection between the first vertical plate 201 and the first flat plate 202.

[0039] A second diagonal brace 303 is provided between the second vertical plate 301 and the second vertical plate 301. The second diagonal brace 303 is used to reinforce the connection between the second vertical plate 301 and the second vertical plate 301.

[0040] In the preferred embodiment, a first connecting groove 205 is provided on one side of the first vertical plate 201, and a second connecting groove 304 is provided on one side of the second vertical plate 301, wherein the first connecting groove 205 and the second connecting groove 304 are fitted together.

[0041] In a preferred embodiment, the bottom end of the cutting rod 101 is provided with a sharp part 104, which facilitates the insertion of the cutting rod 101 into the soil.

[0042] In the preferred embodiment, one side of the first vertical plate 201 is also provided with a plurality of sliding grooves 204, and a sliding seat 206 is provided in the sliding groove 204.

[0043] In the preferred embodiment, a support plate 207 is provided on one side of the slide 206, and a hook 208 is provided on the support plate 207. The hook 208 is used to engage with the arresting cable 103.

[0044] In the preferred embodiment, the bottom of the second plate 302 is also provided with a protruding plate 305, which is made of rubber and is used to compensate for the height difference.

[0045] The first inclined plate 203 and the second inclined plate 303 can also be filled with sand and gravel to increase the counterweight.

[0046] The method of using a water-blocking device for river construction is as follows: During construction, the cutting rod 101 of the cutting assembly 1 is first inserted into the soil at the location where a cofferdam needs to be built upstream of the river through the bottom pointed part 104, forming a horizontally arranged fixed support point. The blocking cable 103 passes through the tensioning pipe 102 on one side of the cutting rod 101, and the tightening seat 106, which is threaded to the outer circle of the tensioning pipe 102, is rotated to tighten the blocking cable 103 and keep it in a taut state.

[0047] Next, the first baffle 2 is installed, and the sliding seat 206 in the sliding groove 204 on one side of the first vertical plate 201 is adjusted to a suitable height so that the hook 208 on the support plate 207 engages with the barrier cable 103, completing the connection between the first baffle 2 and the barrier cable 103. A second baffle 3 is then installed between the first baffles 2, ensuring that the first connecting groove 205 of the first vertical plate 201 precisely engages with the second connecting groove 304 of the second vertical plate 301, forming a continuous water-blocking surface. The rubber protrusion 305 at the bottom of the second flat plate 302 fits tightly against the riverbed, compensating for terrain elevation differences and enhancing sealing.

[0048] Sand and gravel are added to the first inclined support plate 203 and the second inclined support plate 303 to increase counterweight and improve the overall stability of the device. At this time, the first vertical plate 201 and the second vertical plate 301 block the direct impact of the water flow, and the first flat plate 202 and the second flat plate 302 weaken the scouring of the riverbed by the water flow. The impact energy of the water flow is greatly reduced after being buffered by the baffles, so that the downstream initial cofferdam is protected from the impact of strong water flow, the amount of soil loss is significantly reduced, and the initial structure stability of the cofferdam is ensured.

The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
