Embodiment 1

[0035] please see figure 2 , figure 2 It is a schematic cross-sectional view of Embodiment 1 of the Larsen steel sheet pile magnetic waterstop strip of the present invention. As can be seen from the figure, the cross section of the water stop strip in this embodiment includes a raised portion 11 and wings 12 on both sides, the outer edge of the raised portion 11 is arc-shaped, and the raised portion 11 of the water stop strip is opposite to One side is a concave surface, which can increase the softness of the waterstop and save materials. The arc-shaped raised part 11 is placed in the locking gap between the Larsen steel sheet piles. A row of block-shaped magnets 2 is embedded in the protruding part 11 of the waterstop strip, and the row of magnets 2 can be used to adsorb the waterstop strip to the Larsen steel sheet pile.

Embodiment 2

[0038] please see image 3 , image 3It is a cross-sectional schematic diagram of Embodiment 2 of the Larsen steel sheet pile magnetic waterstop strip of the present invention. It can be seen from the figure that the cross-section of the water-stop strip in this embodiment includes a raised portion 11 and wings 12 on both sides. The shape of the outer edge of the raised portion 11 is a top angle with a certain angle. The opposite side of the protruding part 11 is a concave surface, which serves to increase the softness of the waterstop and save material. The protruding part 11 with a top angle is placed in the locking gap between the Larsen steel sheet piles. A row of bar-shaped magnets 2 is embedded in the protruding part 11 of the waterstop strip, and the row of magnets 2 can be used to adsorb the waterstop strip to the Larsen steel sheet pile.

Embodiment 3

[0041] please see Figure 4 , Figure 4 It is a cross-sectional schematic diagram of Embodiment 3 of the Larsen steel sheet pile magnetic waterstop strip of the present invention. It can be seen from the figure that the cross section of the water stop strip in this embodiment includes a raised portion 11 and wings 12 on both sides, the shape of the outer edge of the raised portion 11 is square, and the raised portion 11 of the water stop strip is opposite to each other. The side is concave, and the concave surface can increase the softness of the waterstop and save material. The arc-shaped raised part 11 is placed in the locking gap between the Larsen steel sheet piles. A row of small holes is arranged in the protruding part 11 of the water-stop strip, and powdery magnets 2 are installed inside each small hole, and the water-stop strip can be adsorbed on the Larsen steel sheet pile by using the row of magnets 2 .

Abstract

The invention relates to a Larsen steel sheet pile magnetic water-stop strip. The water-stop strip is a strip-shaped body made of flexible materials, and a magnetic body (2) is embedded in the strip-shaped body along the direction of the water-stop strip. The described water-stop strip The strip-shaped body includes a raised portion (11) in the middle and wings (12) on both sides. The Larsen steel sheet pile magnetic water-stop strip of the present invention has an ideal water-stopping effect for the Larsen steel sheet pile cofferdam construction, and the raised part and the wings on both sides can seal the leakable holes, and because it is made of flexible materials , will not cause water leakage due to the deformation of Larsen steel sheet piles due to external factors such as wind and waves, and has a good ability to resist external harsh environments. It can be used repeatedly and is convenient for construction.

Description

technical field [0001] The invention relates to a water-stop material, in particular to a Larsen steel sheet pile magnetic water-stop strip, which can be used to seal when the Larsen steel sheet pile cofferdam is pumped to reduce external water seepage into the cofferdam. Background technique [0002] Steel sheet piles have been produced in Europe since the beginning of the 20th century. Steel sheet piles include cold-formed thin-wall light and hot-rolled types. Because the former has relatively large processing and use limitations, hot-rolled steel sheet piles have become the mainstream of steel sheet pile product development. Due to the influence of cheap land resources and human resources, and the domestic production is basically in a blank state, the application and development of steel sheet piles as metal building materials in my country is very slow. With the rapid development of my country's economy, various fast, efficient and environmentally friendly construction m...
