1.Drainage consolidation method is applicable to soft soil with thickness greater than 5m, but soft soil with sensitivity of more than 5 is not suitable. 2.The preloading time of drainage consolidation method should be guaranteed for more than 6 months. 3.The construction section of bridge head should be pre compressed before excavation of pile foundations and caps, so as to avoid the displacement of pile foundations and caps due to preloading. 4.In order to improve the overall stability of the embankment and the drainage performance of the cushion, geosynthetics can be installed in the horizontal drainage cushion. 5.The adjacent sections of the structure should be combined with the plastic drain board combined with overloading preloading, and the height of overloading is generally 30% to 50%, with high filling and tight filling period, the vacuum combined loading preloading can be used. PARFECT soil stabilization equipment can transfer the soil binder through the air compressor to th

Because of the lag of soil pollution, and there are many difficulties in the identification and monitoring of soil pollutants in the past, the problem of land pollution has been paid less attention in the past. The relocation and abandonment of industrial enterprises is the product of accelerated urbanization in China in recent years. The relocation of polluting enterprises has been vigorously implemented in various large and medium-sized cities, such as Beijing, Tianjin, northeast old industrial bases, the Yangtze River Delta and the Pearl River Delta. The environmental problem of contaminated land has become an obstacle in the process of land redevelopment. At present, some old industrial districts located in cities cannot be redeveloped due to pollution problems, so they are very concerned by governments and enterprises in recent years. Based on the strong support of national policies, soil remediation industry is gradually emerging. According to the data released by the foresight
