Single-fork net rack used for building dam or intercepting plugging opening

Abstract

Provided is a single-fork net rack used for building a dam or intercepting a plugging opening. Every two frames of a plurality of frames are connected to form a framework; the edge of one frame in theevery two connected frames extends outwards to form a single fork at the junction point, and each fork is connected with net wires to form a single-fork net rack body; every two frames of the multiple single-fork net rack bodies are connected to form a cage body; and the top point of the cage body is a three fork head top point, and the cage body is a three fork head cage body. The single-fork net rack used for building the dam or intercepting the plugging opening has the beneficial effects that the single-fork net rack is manufactured into a semi-finished product component, a regular tetrahedron three fork head reinforcement cage is rapidly assembled on a flood fighting and rescue site, and stone blocks, soil or sand bags are thrown into the reinforcement cage during assembly to form flood fighting and rescue materials; three fork heads are arranged on each direction of the three fork head reinforcement cage, the fork heads are easily inserted into the water or the dam, then other fork heads can hook other reinforcement cages or plug the water to intercept heavy objects, and the rescue effect is improved; each junction point of each net rack body is provided with the fork heads to serve as handles, and carrying is convenient; and meanwhile, the space is not wasted during transportation and storage.

Description

technical field [0001] The invention relates to the technical device field of embankment construction or flood fighting and emergency rescue, in particular to a frame, a grid made of the frame and a cage made of the grid. Background technique [0002] In dam construction, flood fighting and emergency rescue, river closure or dam closure, it is necessary to fill sand, gravel, soil or other heavy objects. At present, stones are generally used for direct plugging. When the stones are not enough, sand or soil are put into sand bags and filled into water to block. However, due to the large flood and turbulent water flow, small stones or sandbags will be washed away by the flood soon. Because the embankment itself is in a dangerous state, it is also difficult to transport large stones or heavy objects by vehicles or cranes. It is difficult to effectively seal the gap. [0003] For this reason, patent application number 2003201097232 has announced a kind of equiangular cone anti-...

AI Technical Summary

Problems solved by technology

The patented product can indeed block the flow, but there are still relatively difficult defects in practical application

1. Only the sharp corners of the tetrahedron are easy to insert into the soil, but in the flood, the soil tends to slurry, and the steel cage is easy to flow with the mud, but it is still unstable; 2. This kind of steel cage has no moving point, w
