Lateral farmland drainage ditch and constructing method thereof

Abstract

The invention relates to a drainage ditch, in particular to a lateral farmland drainage ditch and a constructing method of the lateral farmland drainage ditch. The lateral farmland drainage ditch comprises a ditch wall and a ditch bottom, wherein the ditch wall is composed of an upper face layer and composite layers, the composite layers are arranged below the upper face layer, the upper face layer is a common concrete water-impervious layer, the composite layers are composed of the composite layer I and the composite layer II, the composite layer I and the composite layer II are arranged in a spaced mode in the length direction of the ditch wall, the composite layer I is a sand-free concrete water-pervious layer, the composite layer II is a common concrete water-impervious layer, and the ditch bottom is a common concrete water-impervious layer. Due to the lateral farmland drainage ditch and the constructing method of the lateral farmland drainage ditch, the flood drainage function and the subsurface water control function of farmland can be guaranteed, and the recharge effect of water in the ditch body can also be achieved.

Description

technical field [0001] The invention relates to a drainage ditch, in particular to a lateral farmland drainage ditch and a construction method thereof. Background technique [0002] At present, in the construction of basic farmland, considering the drainage during heavy rain or flood, field drainage ditches of different levels are often set up in the places where water is easy to accumulate in the farmland. [0003] Most of the existing field drainage ditches are designed with masonry or concrete single-layer homogeneous structure, and water outlets are arranged on the lower side of the field to drain excess water from the field surface, or drain water through vertical infiltration of the soil. However, for farmland with heavy soil viscosity, the vertical seepage and drainage function of the soil is almost completely lost. At the same time, the inside of the ditch is completely blocked from the outside soil. Common drainage ditches can only discharge excess water from the f...

AI Technical Summary

Problems solved by technology

Common drainage ditches can only discharge excess water from the field surface and the upper layer of the soil, but cannot drain the water from the middle and lower layers of the farmland soil, completely losing the requirement for farmland drainage

[0004] In the dry season, due to the impermeable structure of the masonry or concrete ditch bottom and both sides of the ditch wall, the water stored in the ditch cannot seep back into the field soil, resulting in a waste of water resources
