Description

Technical Field

[0001] The utility model relates to the technical field of cut-off walls, in particular to a cut-off wall for water conservancy projects. Background Art

[0002] The cut-off wall is used to prevent groundwater or other fluids from penetrating into the water conservancy project structure through soil or rock formations. The cut-off wall is usually a wall cast with concrete. When constructing the cut-off wall, a pit is dug in the anti-seepage area, and then concrete is poured to cast the wall.

[0003] The inventor found in daily work that when the cut-off wall is in use, since the cut-off wall is usually a wall cast with concrete and no support is provided, the strength and anti-seepage strength of the concrete are relatively low. Generally, a steel bar framework is arranged inside the concrete to enhance the strength of the concrete. When the steel bar framework is built, after the X-axis steel bars and the Z-axis steel bars are tightened with wire, then the Y-axis steel bars and the Z-axis steel bars need to be tightened with wire. Since there are many nodes between the X-axis steel bars, the Y-axis steel bars and the Z-axis steel bars, the method of binding with wire is very troublesome, which may indirectly affect the efficiency of constructing the cut-off wall.

Generally, a steel bar framework is arranged inside the concrete to enhance the strength of the concrete. Since when the steel bar framework is built, the X-axis steel bars and the Z-axis steel bars are tightened with iron wires, and then the Y-axis steel bars and the Z-axis steel bars also need to be tightened with iron wires. Since there are many nodes between the X-axis steel bars, Y-axis steel bars, and Z-axis steel bars, the method of binding with iron wires is very troublesome, which may indirectly affect the efficiency of building the cutoff wall.

The extrusion block one 26 extrudes the X-axis steel bars 22, and the extrusion block two 27 extrudes the Y-axis steel bars 23, thereby fixing them. Then, multiple X-axis steel bars 22, Y-axis steel bars 23, and Z-axis steel bars 21 are fixed in the above manner, and then placed into the pit dug in the seepage-proof area. Then, concrete is poured, so as to facilitate the fixing of multiple X-axis steel bars 22, Y-axis steel bars 23, and Z-axis steel bars 21 as much as possible. By setting anti-slip stripes, the extrusion block one 26 is assisted to limit the X-axis steel bars 22, and the extrusion block two 27 is assisted to limit the Y-axis steel bars 23. By setting the mesh layer 31 and the waterproof cloth one 32, after the concrete is poured into the pit, the mesh layer 31 is inserted into the concrete, and in cooperation with the waterproof cloth one 32, auxiliary waterproofing is carried out. By setting the waterproof cloth one 32 and the waterproof cloth two 34, after the waterproof cloth one 32 is connected to the waterproof cloth two 34 through the adhesive layer 33 and then inserted into the concrete along with the mesh layer 31, the waterproof cloth one 32 and the waterproof cloth two 34 are nylon waterproof cloths. By setting the waterproof coating layer 35 and applying it to the waterproof cloth two 34, auxiliary waterproofing is carried out. The waterproof coating layer 35 is a polyurethane waterproof coating.
