A kind of double fork net frame used for building dams or intercepting and blocking

Abstract

The invention discloses a double-jaw net rack used for dyke constructing or closure plugging. Every two frames of multiple frames are jointed to form a framework, and the side end of every two adjacent frames extends outwards at the joint to form double jaws which cross each other. Net wires are mounted in the framework to form a double-jaw net rack body. Every two frames of a plurality of double-jaw net rack bodies are mutually spliced to form a cage body. The peak of the cage body forms the peak of a three jaw. The cage body forms a three-jaw cage body. The double-jaw net rack has the beneficial effects that the double-jaw net rack bodies are manufactured into semi-finished product component, and a regular tetrahedron three-jaw cage body is rapidly assembled in the flood-fighting and emergency rescue field; during assembling, stones or soil or sandbags are placed in a reinforcement cage, and effective flood-fighting and emergency rescue goods and materials are formed; three jaws are formed in each direction of the three-jaw reinforcement cage, the reinforcement cage can be easily inserted into the water bottom or a dyke, then the other jaws can hook other reinforcement cages or water plugging and closure weights, and the emergency rescue effect is improved; jaws are arranged at each joint of the net rack and can be used for hand shanks, so that carrying is facilitated; and meanwhile, the space is not wasted during transportation and storage.

Description

technical field [0001] The invention relates to the technical equipment field of embankment construction or flood fighting and emergency rescue, in particular to a double-prong network frame used for embankment construction or interception and plugging. Background technique [0002] In the work of building embankments, flood fighting and emergency rescue, river closure or embankment plugging, sand, gravel, earth or other heavy objects need to be filled. 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 200320109...

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, whether it is manual handling or locomotive handling , it is not easy to carry at the emergency site, which makes it difficult to carry; the frames of the 3-triangular grid frame are fixed by screws, and screws, nuts and wrenches are needed for emergency assembly on site, and it is not easy to arrange them in an emergency, which affects the speed of emergency rescue
