Problems solved by technology

[0004] However, if the connection between the steel sheet piles is not tight enough, water leakage points will easily appear, and damage to the steel sheet piles will also easily lead to water leakage points. The water at the water leakage point seeps from the outside of the cofferdam to the inside of the cofferdam Therefore, if the leaking water point is blocked with repair materials inside the cofferdam, the plugging material will be easily washed away by the seepage water. If the leaking water point is repaired outside the cofferdam, because the containment The outside of the weir is soaked in water. It is difficult for construction workers to dive into the water that is too deep. Even if they enter the water, it is difficult to find the exact location of the leakage point, and the repair in water is difficult and expensive.

Embodiment 1

[0040] like figure 1 , 7 As shown, it is a repair body for repairing a leaky water point of a cofferdam disclosed in the present invention, comprising a base layer 2 located on the outer layer and plugging particles 3 wrapped in the base layer 2 .

[0041] The base layer 2 is made of silty clay, so the density of the base layer 2 is greater than that of water, and the silty clay will disperse in water for a long time, while the plugging particles 3 can be one or more of dry sawdust and dried kelp particles , so the density of the blocking particles 3 is lower than that of water, and the blocking particles 3 are insoluble in water and do not react with water. In addition, the blocking particles 3 also have the feature of swelling in contact with water. The plugging particles 3 also have the characteristics of uniform gradation, that is, the particle sizes of all the plugging particles 3 are uniformly distributed from small to large, and the maximum size of the plugging particl...

Embodiment 2

[0047] Compared with the first example, the difference is:

[0048] like figure 2 As shown, the base layer 2 is in the shape of a rectangular block, and the blocking particles 3 are not wrapped in the base layer 2 but mixed with the base layer 2 . When the base layer 2 is decomposed, the plugging particles 3 originally mixed with the base layer 2 will also be separated from the base layer 2 , and then escape into the water and then float up to block the leaking water point 5 .

Embodiment 3

[0050] Compared with the first example, the difference is:

[0051] like image 3 As shown, in addition to being wrapped inside and outside the base layer 2 , the plugging particles 3 are also embedded in the outer surface of the base layer 2 . Therefore, the restoration 1 can accommodate more plugging particles 3, and then the base layer 2 can be dissolved or dispersed in water to allow more plugging particles 3 to escape into the water, so as to achieve better plugging of leaking water points. 5 effects.

Abstract

The invention relates to a repairing body for repairing a cofferdam leakage water point and a cofferdam leakage water point repairing method. The repairing body comprises a base layer and blocking particles connected to the base layer, wherein the base layer is dissolved in water or dispersed by water. The density of the blocking particles is less than that of water. The blocking particles are insoluble in water and do not react with water. The overall density of the repairing body is larger than the density of water. The repairing body has the effects of effectively and conveniently repairingthe leakage water point.

Description

technical field [0001] The invention relates to the technical field of repairing water leakage points in cofferdams, in particular to a repair body for repairing leakage water points in cofferdams and a method for repairing leakage water points in cofferdams. Background technique [0002] Cofferdam refers to the temporary enclosure structure built during the construction of the project. Its function is to prevent water and soil from entering the construction site of the building, so as to drain the water in the cofferdam, excavate the foundation pit, and build the building. Generally mainly used in hydraulic construction, except as part of formal buildings, cofferdams are generally demolished after use. [0003] At present, the Chinese Patent Application Publication No. CN108824461A discloses a Larsen steel sheet pile cofferdam and a construction method thereof. The main points of the technical solution are: including a first Larsen steel sheet pile and a second Larsen stee...
