Ecological lining brick for farmland drainage channel

Abstract

The invention discloses an ecological lining brick for a farmland drainage channel. The ecological lining brick comprises a concrete frame and zeolite bricks, wherein the concrete frame is detachably connected with the zeolite bricks; the concrete frame is provided with clamping grooves capable of accommodating the zeolite bricks; the zeolite bricks are embedded into the clamping grooves; each zeolite brick comprises an outer frame and a filler; the filler is arranged in an inner cavity of the outer frame; the filler is zeolite; and the outer frame is provided with a plurality of through holes. According to the ecological lining brick for the farmland drainage channel, the concrete frame can effectively stabilize the slope top and the slope toe of a drainage channel slope and enhance the slope stability; when the zeolite bricks are soaked in farmland tail water, the zeolite bricks can play a role in adsorbing residual pollutants in the water; after drainage is finished, the zeolite bricks are exposed in the air, and the adsorbed pollutants volatilize to be recycled for next drainage; and the zeolite bricks are detachably connected with the concrete frame, so that the failed zeolite bricks are convenient to replace, and the purification capacity of the drainage channel is guaranteed.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation and drainage engineering, in particular to an ecological lining brick for farmland drainage ditches. Background technique [0002] There are three main types of existing farmland drainage ditches, soil drainage ditches, hardened drainage ditches and general ecological slope protection. Among them, the soil drainage ditch can use the infiltration of soil to control the groundwater level of the farmland, drain waterlogging and reduce waterlogging, but the stability of the slope is poor, the flow section is large, and the soil of the slope is easily eroded by the water flow to cause siltation, and the maintenance cost of dredging High; the hardened drainage ditch improves the stability of the section, but causes permanent damage to the material and energy exchange function of the drainage ditch, which is not conducive to farmland drainage and ecological balance; general ecological slo...

Among them, the soil drainage ditch can use the infiltration of soil to control the groundwater level of the farmland, drain waterlogging and reduce waterlogging, but the stability of the slope is poor, the flow section is large, and the soil of the slope is easily eroded by the water flow to cause siltation, and the maintenance cost of dredging High; the hardened drainage ditch improves the stability of the section, but causes permanent damage to the material and energy exchange function of the drainage ditch, which is not conducive to farmland drainage and ecological balance; general ecological slope protection takes into account both slope stability and biodiversity , but does not consider the pollution of downstream water bodies by farmland pollutants such as chemical fertilizers and pesticides, which expands the impact of agricultural non-point source pollution
