For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the term "provided with" that may appear should be understood in a broad sense. For example, the object "provided with" may be a part of the body, or may be arranged separately from the body and connected to the body, and the connection may be a detachable connection or an inseparable connection. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] The present invention is further described in detail below in conjunction with the embodiments.

[0027] Specific embodiments of the auxiliary tool provided by the utility model for preventing the loss of the filter material of the old structure foundation of the sluice:

[0028] See also Figure 1-5 , an auxiliary tool for preventing the loss of filter material from the old structure foundation of the sluice, including a plurality of mesh wires 1, a plurality of side wires 2 and a plurality of reinforcing structures; each reinforcing structure includes two reinforcing wires 3. In this embodiment, the mesh wires 1, the side wires 2 and the reinforcing wires 3 are all galvanized alloy steel wires.

[0029] A plurality of mesh wires 1 are intertwined to form a mesh structure, such as Figure 1 and Figure 2 As shown, the mesh of the mesh structure is a hexagonal hole, and the two opposite sides of the hexagonal hole are formed by twisting and entwining two strands of mesh wire 1. The mesh size is smaller than the particle size of the surface filter material, which can effectively prevent the loss of the filter material.

[0030] The edge wires 2 are butted against each other to form a ring structure, which corresponds to the edge of the mesh structure and is wound and connected; specifically, the ends of the mesh wires 1 at the edge of the mesh structure are all wound around the outside of the edge wires 2; the edge wires 2 make the mesh holes at the edge of the mesh structure semi-hexagonal holes.

[0031] The reinforcing structure corresponds to the position where the adjacent side wires 2 abut against each other. The ends of the two reinforcing wires 3 of the reinforcing structure are respectively twisted and connected with the ends of the two abutting side wires 2. The reinforcing wires 3 pass through the mesh structure and are twisted and twisted and connected with the mesh structure.

[0032] In this embodiment, the reinforcing structure also includes a plurality of tying wires 4, which are evenly arranged along the reinforcing wires 3 and bundle the two reinforcing wires 3 together; for key positions, such as the ends of the reinforcing wires 3, it is necessary to set tying wires 4 to bundle the ends of the two reinforcing wires 3 so that the connection between the two side wires 2 is stable.

[0033] The metal mesh available on the market often needs to be spliced ​​because the size specifications do not match the filter material area. The joints of the spliced ​​metal mesh are difficult to prevent the loss of filter material, and the edges are not easy to fix. However, with this tool, the flexible mesh made of galvanized alloy steel wire can be woven according to the filter material area at the bottom of the old concrete structure. It has strong ductility and flexible size, and can be used for the renovation of various sluices. The integral mesh structure has no large-scale joints and high strength. The edges are surrounded and connected by the annular structure formed by the side wires 2, which makes the edge structure of the flexible mesh stable and reduces the deformation of the mesh structure. The side wires 2 are tightly connected at the abutment points through the reinforcement structure, and the side wires 2 are connected to the mesh structure at the abutment points through the reinforcement structure, so as to avoid separation at the abutment points of the side wires 2 and improve the integrity.

[0034] The flexible net is fixed with a number of steel nails 5, which are evenly arranged along the annular structure and pass through the winding connection between the annular structure and the mesh structure, that is, the winding place between the mesh wire 1 and the edge wire 2. The steel nails 5 are nailed into the bottom edge of the old structure foundation to ensure that the mesh structure covers the outside of the anti-filter material to protect the anti-filter material.

[0035] Since the head area of ​​the steel nail 5 is limited and it is difficult to effectively press the edge wire 2, a number of annular pressing plates 6 are provided, and the steel nails 5 correspond to the pressing plates 6 one by one and pass through the corresponding pressing plates 6; the pressing plates 6 are located outside the connection between the annular structure and the mesh structure and inside the head of the steel nail 5. The pressing plates 6 are provided with reinforcing ribs 61 on the side facing the head of the steel nail 5. When the steel nail 5 is driven in, the head of the steel nail 5 applies pressure to the pressing plates 6, and the reinforcing ribs 61 reduce the deformation of the pressing plates 6; the pressing plates 6 are evenly provided with a number of claw teeth 62 on the side facing away from the head of the steel nail 5, that is, on the edge of the old structure foundation side. The pressing plates 6 are pressed on the outside of the ends of the edge wire 2 and the mesh wire 1, and the edge wire 2 and the mesh wire 1 are located between the claw teeth 62. The pressing plates 6 and their claw teeth 62 can limit the positions of the edge wire 2 and the mesh wire 1, reduce the pulling and dislocation of the edge wire 2 and the mesh wire 1, and avoid the mesh wire 1 and the edge wire 2 from being entangled and separated from the connection structure.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments without creative work, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
