高速防水板設施安裝注意事項
    山東萊蕪同利土工合成材料有限公司為大家分析高速公路排水設計應包含的必要性，主要包括以下兩個方面的內容：

Shandong Laiwu with the benefit of geosynthetic material limited company to the necessity of highway drainage design should contain, mainly includes the following two aspects:

一是要考慮如何減少地下水、農田排灌水對路基穩定性及強度的影響，一般稱之為第一類排水；二是要考慮如何將路表水迅速排出路基之外，最大限度地減少雨水對路基、路面質量的影響，減少因路表水排水不暢或路表水下滲對路基、路面結構和使用性能產生的損害，這稱為第二類排水。高速公路路面滲水的排水設計沿路面邊緣設置由透水性填料集水溝、橫向出水管和排水網組成的路面邊緣排水系統。

One is to consider how to reduce groundwater, irrigation and drainage effects on the stability and strength of subgrade, commonly known as the first drainage; two is to consider how to rapidly discharge the roadbed road surface water, to minimize the effect of rainfall on subgrade, pavement quality, reduce the road surface water drainage is poor or road surface water infiltration of the roadbed, pavement structure and performance of damage, which is called the second type of drainage. The drainage design of Expressway Pavement seepage along the pavement edge setting pavement edge drainage system composed of ditch, transverse pipe and drainage network composed of permeable filler set.
