Natural grass bed construction method is different from other sites in soil processing. To meet the requirements of the design documents, it is also necessary to meet the growth of planting grass seedlings to achieve a good drainage effect. The construction method focuses on the following: 1. Measure the payoff line work, use the field center pile to control the exact position of the site, use the coordinate method to place the four corner kicks accurately, and use the diagonal measurement data to check the size and angle of the site, or use different from the test Another method of checking. In the leveling construction work of each structure, the height control method is a square grid method, and the vertical and horizontal slope method is not used, and the size of the square grid is 5mx5m. 2. After the earthwork on the site is completed, roller compaction shall be carried out in the whole site. Light roller grinding or vibratory roller compaction shall be adopted. The grind weight shall not be less than 12t. One purpose is leveling. One purpose is to make the site dense and uniform and prevent uneven settlement on the site. Serious and uneven high and low phenomena should be taken as high as possible, fill in low treatment, and the density of compaction can be up to 95%. There should be no tumbling. If there is a slush, it should be treated thoroughly. It is not allowed to use only the bulldozer. Leveling is used for the next process, because sometimes there will be a large area of ​​uneven settlement after use, affecting the use and maintenance of the lawn. 3. The gravel layer and gravel layer play the role of water seepage. The materials used in the construction should be clean and free from dirt. After the materials are applied, they should be stratified. The thickness of each layer should not exceed 20cm. After the paving is completed, large crawler bulldozers can be used. Rolling the whole field, at least two times. 4. Blind ditch construction. Blind ditch construction is to carry out trenching after the first layer of drainage grit layer is completed. Each blind ditch should have a good drainage gradient, and the ditch should be smooth and smooth, and it must not be uneven and there should be no backwater. Gradient, after placing the filter pipe, gravel on both sides of the card is stable, and both sides of the backfill gravel and fill the gravel with steel fiber transplanting, compact, large gravel in the following, coarse gravel, fine gravel, sand and other layered filling It must not be randomly filled in, and finally the excavated earth should be transported off site. 5. Currently backfilled sand is taken from riverbeds, mountain sands and other nature. Sand contains a large number of pathogenic bacteria, nematodes, and weed seeds. Therefore, disinfecting is required during soil mixing to eliminate these pests. Before, it was necessary to wait for a period of time after the sand came to be sterilized. 6. In order to strengthen the stability of the grass seedlings, in order to strengthen the stability of the grass seedlings, a layer of tensile material is laid in the sand layer under the surface planting soil. The tensile material is a grid-like coiled material, and the grid is not more than 1 cm. The roots of the grass seedlings pass through the tensile grid material, enhancing their mutual intersection and preventing the turf from taking off large areas of the soil from the soil layer when the athletes perform the action. 7. Before the grass is planted, make the last measurement, check the elevation, slope, and trim leveling. The general flatness error should not exceed 1cm. Our shampoo chair features a modern design with a large ceramic bowl and a reclining design for extra comfort. The seat is made of high-density sponge with FRP metal base structuring, for long service life.
