Description
Technical Field
The invention relates to the technical field of dam building or flood fighting and emergency rescue equipment, in particular to a three-frame folding type three-fork-head quadrangular cage body assembly for dam building or closure plugging.
Background
In the work of building dam, fighting flood, cutting off river or blocking up dam, it is necessary to fill gravel, soil or other heavy objects. At present, the direct filling of stones is generally adopted, and when the stones are insufficient, gravels or soil are filled into sand bags and filled into water to block the stones. However, because of the large flood and the turbulent flow, the stones or sand bags are quickly washed away by the flood, and the dam is in a dangerous state, and is difficult to transport a large amount of stones or heavy objects by vehicles or cranes, so that the gap is difficult to effectively block.
For this reason, patent No. 201610656081X discloses a double-prong net frame for building a dam or closure, which comprises a plurality of frames connected two by two to form a frame, and the edge ends of every two adjacent frames extending outward at the joint to form the intercrossed double-prong; connecting net wires in the frame to form a double-fork net rack; the frames of the double-prong net racks are connected in parallel pairwise to form a cage body, the vertex of the cage body becomes the vertex of the three-prong, and the cage body becomes the cage body of the three-prong; the patent is that a double-fork net frame is made into a semi-finished product part, a regular tetrahedron three-fork reinforcement cage is quickly assembled on a flood fighting site, and stones, soil or sandbags are placed in the reinforcement cage during assembly to form effective flood fighting materials; three forks are arranged in each direction of the three-fork-head reinforcement cage, so that the three-fork-head reinforcement cage can be easily inserted under the water bottom or into a dam, and then other forks can hook other reinforcement cages or water blocking closure weights, so that the emergency rescue effect is improved; a fork head is arranged at each connecting point of the net rack and can be used as a handle, so that the net rack is convenient to carry; and does not waste space during transportation and storage.
The product of the patent has good practicability, convenient operation and labor saving, and has good flood fighting and emergency rescue effects. However, in the process, firstly, a double-fork frame or a double-fork net rack is made, and then the double-fork frame or the double-fork net rack is spliced into a three-fork frame body or a three-fork cage body, so that the double-fork frame or the double-fork net rack is convenient to stack so as to save transportation and storage space, but three defects exist, namely, the stacking and assembling method is inconvenient and more convenient; secondly, the frame strips are repeated after the assembly, so that the three-prong becomes thick, the resistance of inserting into the water bottom mud can be increased, or the chance of hooking the three-prong frame body or the three-prong cage body thrown in front is reduced; and after the frame strips are assembled, the frame strips are repeated, and materials are wasted.
Patent application No. 2016106560862 discloses a single-prong net rack for building dam or closure, which is different from a double-prong net rack in that the edge of one of every two interconnected frames extends outward at the junction to form a single prong, and a mesh wire is attached in the frame to form the single-prong net rack; the frames of the single-prong net racks are connected in parallel pairwise to form a cage body, and the top point of the cage body is a three-prong top point; the fork rod of the three-fork head is not repeated, but the frame strips of the frame body or the cage body are repeated, so that the material is wasted; more importantly, the assembly mode is the same as the assembly mode, the assembly mode is still inconvenient, and better stacking and unfolding effects cannot be achieved.

In practical application, the three-prong on the vertex of the three-prong quadrangular cage 1 can be reduced as required to be made into a single prong or a double prong, and the three-prong quadrangular cage is changed into a single-prong quadrangular cage or a double-prong quadrangular cage; or the forks on the top point of the cage body are added to be made into a four-fork head, a five-fork head or more fork heads, and the three-fork head quadrangular cage body is changed into a four-fork head quadrangular cage body, a five-fork head quadrangular cage body or more fork head quadrangular cage bodies, or a mixed fork head quadrangular cage body.
The cross-connecting manner of the frame strips is not limited, and the frame strips can be bound, fastened, screwed, and the like.
The frame strips 11, also called skeleton strips or main ribs, may be made of metal material, or may be made of other hard materials, such as steel, alloy copper material, hard alloy, PVC material, etc., preferably made of metal material with relatively high density.
The three-frame folding type three-fork quadrangular cage body assembly is used for dam construction, river closure, dam plugging, flood fighting and emergency rescue, lake surrounding and land building, sea surrounding and island building and bridge building and foundation digging.
