How To Build Water Channel In Farmland !
1. Preparation
Before construction, it is necessary to carefully plan and measure the location and size of farmland drainage ditches. It is necessary to determine the depth, width and length of the gutter, while taking into account rainfall and soil permeability, to determine the slope and drainage capacity of the gutter !
2. Construction Steps
(1). Trench excavation
According to the predetermined position and size, use excavators or manual excavation of soil, the trench excavation to the specified depth and width !
(2). Gutter bottom treatment
In order to improve the drainage effect, it is necessary to lay drainage sand and drainage bricks and other materials at the bottom of the gutter, so that the soil can quickly penetrate into the drainage layer at the bottom of the ditch, so as to achieve the purpose of drainage !
(3). Install piers
If the new drainage ditch needs to cross roads or ditches and other places that need to be used, it is necessary to install piers on the drainage ditch. The height and width of the pier should be adjusted according to the actual situation !
(4). Install isolation belts
In order to prevent soil and weeds and other debris from entering the gutter, isolation belts need to be installed on both sides of the trench, generally made of stone or cement !
(5). Determine the drainage slope
Determine the slope of the drainage ditch according to the length and depth of the drainage ditch. In general, the slope of the gutter should be greater than 0.5% !
(6). Lay drainage pipes
Lay drainage pipes in the drainage ditch, and ensure that there is a certain distance between the drainage pipe and the bottom of the drainage ditch, so that the soil can penetrate into the pipe smoothly !
(7). Determine the position of the drainage outlet
Set the drainage outlet at the end of the drainage ditch to discharge the water from the farmland in time !
3. Precautions
(1). Before the construction of farmland drainage ditch, factors such as drainage capacity, slope and length should be fully considered to ensure that the drainage ditch can play the best drainage effect !
(2). Special personnel should be arranged to supervise and manage the construction process, and timely find and deal with the construction problems !
(3). Before the construction of the drainage ditch, the excavated soil needs to be treated and utilized to ensure the rational utilization of resources and environmental protection !
(4). Keep the site clean and tidy in the construction process to avoid polluting the environment !
In short, farmland drainage ditch is a very important facility in agricultural production, which can help farmers solve drainage problems and ensure the good growth of crops. During construction, we should carefully plan and carry out construction in accordance with standards to ensure the effectiveness and sustainability of the drainage ditch !
