Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction equipment, specifically a water conservancy construction cofferdam mechanism. Background Technology

[0002] During the construction of water conservancy projects (such as dams, pumping stations, and locks), the foundations or other key parts of the structures to be constructed are isolated from the water body. For example, when building the foundation of a dam, the construction site is enclosed by a cofferdam, allowing the construction area to be carried out in dry conditions, avoiding interference from water flow, and facilitating construction workers to carry out tasks such as foundation excavation and concrete pouring. It can also guide the water flow along a predetermined route. For example, when constructing in a river, by setting up a cofferdam appropriately, the direction of water flow can be changed to prevent water from eroding the construction site. At the same time, it is also beneficial to drain water within the area enclosed by the cofferdam, maintaining a relatively dry environment in the construction area.

[0003] Cofferdams are subjected to long-term water erosion, especially in areas with high water velocity, such as the outer side of river bends. The scouring force of the water will gradually erode the water-facing side of the cofferdam. Without effective anti-erosion measures, the cofferdam may be washed away, causing seepage and overall collapse. Utility Model Content

A positioning seat is fixedly installed on the surface of the retaining pipes, and the surfaces of the multiple groups of retaining pipes are covered with a water-proof plate. At the same time, the surface of the water-proof plate is covered with a sealing cloth. A first positioning hole is opened on the positioning seat, and a second positioning hole is opened on one side of the first positioning hole.

[0006] Preferably, the baffles are arranged in multiple groups at equal intervals, and each group of baffles is equipped with a buckle. At the same time, the back of the multiple groups of baffles is fixedly connected to the first support tube, the second support tube, and the third support tube respectively through the buckles.

[0007] Preferably, the spacing between the first support tube, the second support tube and the third support tube is the same, and the three sets of support tubes are arranged in parallel, while the diameters of the first support tube, the second support tube and the third support tube are the same.

[0008] Preferably, a pin is fixedly installed at the bottom of the retaining pipe, and the pin is tapered. At the same time, multiple sets of pins are inserted into the bottom of the riverbed through the pins at the bottom.

[0009] Preferably, the surface of the water stop plate is uniformly provided with multiple groups of water retaining plates with isosceles trapezoidal section, and the distance between adjacent two groups of water retaining plates is consistent.

[0010] Preferably, the front surface of the water stop plate is provided with sealing cloth, and the sealing cloth is waterproof geotextile, and the back surface of the water stop plate is fixedly provided with a connecting seat.

[0011] Preferably, the connecting seat is uniformly provided with four groups, and the four groups of connecting seats are oppositely provided with the four groups of positioning seats.

[0012] Preferably, the bottom of the four groups of connecting seats is respectively provided with a first positioning column and a second positioning column, the first positioning column and the second positioning column are matched with the size of the first positioning hole and the second positioning hole, and the first positioning column and the second positioning column are respectively inserted into the first positioning hole and the second positioning hole.

[0013] Compared with the prior art, the utility model has the advantages that:

[0014] 1. The water stop plate can effectively block water flow and silt, has high strength and good sealing property, can prevent river water from seeping into the cofferdam, has good protection effect on the construction area in the cofferdam, can resist the scouring of water flow, and disperses the impact force of water flow on the cofferdam to a certain extent.
