铺设排水沟盖板时要先做好排水渠，排水排水管道先预埋好，排水渠的外口宽应该是玻璃钢格栅宽度不超过5%，内口宽应该是玻璃钢格栅宽度小于10%，内口宽越小，格栅的承载力就越大，但是小了排水能力就下降，所以一定要控制好比例。
When laying drainage ditch cover, drainage pipes should be pre-buried. The outer width of drainage ditch should be less than 5% of the FRP grid width, and the inner width should be less than 10%. The smaller the inner width, the greater the bearing capacity of the grid. But the smaller the drainage capacity, the lower the drainage capacity, the better the proportion must be controlled.
排水渠好以后，开始正式铺设格栅，把格栅按照需求平铺在排水渠的内口上，做到格栅四周，与排水渠外口的距离相等，使得后期受力均匀。
After the drainage canal is finished, the grille is laid formally, and the grille is laid on the inner opening of the drainage canal according to the demand. The distance between the grille and the outer opening of the drainage canal is equal, so that the stress in the later period is even.
固定格栅，在四周用705玻璃胶把缝隙填满，待胶水干以后用302水泥把缝隙处的胶水掩盖。
Fixed the grille, fill the gap with 705 glass glue around it, and cover the gap with 302 cement when the glue is dry.
后期处理，铺设完以后检查铺设是否到位，进行受力测试等确保工程质量。
Later treatment, after laying, check whether the laying is in place, carry out stress testing, etc. to ensure the quality of the project.
