Combined paddy field cofferdam

Abstract

A combination-type paddy field cofferdam ridge comprises water channel ridge block assemblies and plate-shaped ridge block assemblies, wherein each water channel ridge block assembly comprises three-way channel ridge blocks, the three ends of each three-way channel ridge block are connected with straight through channel ridge blocks, the straight through channel ridge blocks are further connected with the two ends of each crooked wall channel ridge block, inner cavities of the three-way through channel ridge blocks, inner cavities of the straight through channel ridge blocks and inner cavities of the crooked wall channel ridge blocks are communicated through water ports in ends, and each plate-shaped ridge block assembly comprises a connection plate, a straight connection plate, a crossed connection plate, a partition ridge plate, a T-shaped connection plate, a right-angle connection plate, a port-sealing connection plate and a reinforcing pin. The plastic structure is low in weight, it is needless to invest a large amount of labor, materials and transport capacity during combination and installation, the inner cavities of the ridge blocks are communicated, a traditional water channel is replaced, the structures of the plate-shaped ridge blocks hardly occupy land, the structures are easy to combine and install, the cofferdam ridge is suitable for industrial production, the ridge blocks are coated with noctilucent materials, operations can be safely carried out at night, safety of pedestrians is guaranteed, and the beautifying and sightseeing functions are achieved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a combined paddy field cofferdam ridge. Background technique [0002] When planting rice, according to the topographical conditions of the land, it is necessary to manually or mechanically build soil ridges to form cofferdams, and divide large land into several small lands, which is conducive to soaking the land with water, preventing water and fertilizer loss and management . There are many deficiencies in the cofferdam formed by the earth ridge. First, the earth ridge occupies a large amount of effective arable land area, which generally accounts for 4% to 5% of the arable land area according to estimates; and material resources to re-build the ridge, and more people must take care of the ridge from site preparation to harvest to prevent the ridge from being damaged and collapsed. When water is needed, the soil ridge is dug, and when water is not needed, the soil ridge ...

AI Technical Summary

Problems solved by technology

Therefore, the processing and assembly cost of blocks is higher than that of soil ridges

The second is that the structural design of the block is limited by the formwork structure, and the connection can only be realized with a simple convex-concave tenon or groove structure, because a certain gap must be left at the connection between the convex-concave tenon and the groove, and it is inevitable that there will be a gap in the gap. Water leakage; third, the cofferdam ridge does not have the function of a water channel, and the same block structure is used outside the field ridge to form a water channel, and the function of the cofferdam ridge is single; fourth, the cofferdam ridge is wider, which undoubtedly occupies a part of the arable area; fifth is According to the characteristics of concrete, concrete blocks are affected by freezing and thawing, and the calendered layer on the surface is easy to fall off and damage
