Farmland ecological drainage ditch embankment brick, embankment structure and construction method

Abstract

A farmland ecological drainage ditch embankment brick comprises an A-type embankment brick body and a B-type embankment brick body which are matched with each other. The A-type embankment brick body comprises an A-type embankment brick main body, a first through hole is formed in the center of the A-type embankment brick main body in the height direction, and two grooves are formed in the two sides of the A-type embankment brick main body correspondingly and located on the two sides of the first through hole correspondingly; the B-type embankment brick body comprises a B-type embankment brick main body, a second through hole is formed in the center of the B-type embankment brick main body in the height direction, and two protrusions are arranged on the two sides of the B-type embankment brick main body correspondingly and located on the two sides of the second through hole correspondingly; and the protrusions of the B-type embankment brick body are engaged with the grooves of the A-type embankment brick body. An embankment structure comprises a plurality of embankment layers which are arranged from top to bottom, the upper embankment layers are outwards staggered by 4 cm relative to the adjacent lower embankment layers, and each embankment layers comprises the multiple A-type embankment brick bodies and B-type embankment brick bodies. The invention further discloses a construction method of the embankment structure. The farmland ecological drainage ditch embankment brick and the embankment structure are good in water permeability and rapid in construction, saves the ditch occupied area and increases the land utilization rate.

Description

technical field [0001] The protective bricks and protective structure of the farmland ecological drainage ditch are designed for the large area of ​​the existing soil ditch and the slope is easy to collapse. In order to better meet the stability of the ditch, on the basis of the original ecological bricks, the bricks can be meshed, and side slope piers are set along the direction of the ditch. Farmland ecological drainage ditch protective bricks and protective structures are important components of ecological agriculture. Background technique [0002] Farmland drainage ditches are mainly responsible for the two functions of reducing waterlogging and removing surface water. To meet the needs of waterlogging, the depth of farmland drainage ditches generally reaches 1-1.2 m. Considering the needs of slope stability, the slope coefficient of soil slopes is generally m=1-1.5. Therefore, the mouth width of soil drainage ditches is 2-4m. This will occupy a large amount of cultiva...
