竹网+土工织物在软土地基浅表层处理中的应用

竹网+土工织物是一种以原生竹材为主要施工材料处理松软地基表层的工艺。该工艺一般为绑扎竹网配以土工布等土工合成材料,形成加筋半刚性体,上覆一定厚度的砂或土垫层以增强软土地基表层承载力,满足作业面轻型、中型设备施工条件的要求。在汕头市东部经济带市政基础设施建设项目WE3路浅表软基处理施工中,结合现场淤泥层厚度采用了竹网浅表软基处理工艺,有效地提高了施工进度,节约了施工成本。

Application of bamboo net and geotextile in shallow surface treatment of soft ground

The bamboo net and geotextile technology takes the bamboo as the main construction material to deal with the surface of soft ground.Binding the bamboo net with geotextiles and other geosynthetics to form a reinforced semi-steel body,the upper surface of which is covered with the sand layer or soil cushion with a certain thickness to enhance the bearing capacity of the soft ground base and meet the requirements of the operation surface for the light & medium sized equipment construction.In the WE3 road surface soft foundation treatment of the eastern part of the economic zone and municipal infrastructure construction projects of Shantou city,according to the thickness of the silt layer,we adopt the bamboo net treatment technology,and quicken the construction progress and save the construction cost.
