Variable-dosage modified bentonite vertical antifouling barrier wall structure
The invention discloses a variable-dosage modified bentonite vertical antifouling barrier wall structure, and belongs to the technical field of urban underground water and soil pollution prevention and control. The vertical antifouling barrier wall is arranged on the periphery of a polluted site, is vertically inserted into a soil body, and comprises a wall body, a double-layer V-shaped HDPE geomembrane, a protective frame and a guide wall, and sisal fibers are doped in the uppermost composite modified bentonite layer, so that the crack resistance is improved. A double-layer V-shaped HDPE geomembrane is inserted into the shallow foundation part of the wall body, and various sensors are arranged on the two sides of the bottom of the wall body respectively. The vertical anti-fouling barrier wall structure effectively solves the problem that a vertical wall fails quickly due to the fact that a shallow foundation of the vertical anti-fouling barrier wall is weak and a dominant seepage channel is easy to form. And meanwhile, on the premise of achieving the optimal use effect, the use amount of bentonite is saved, and the construction cost is reduced.
本发明公开了一种变掺量改性膨润土竖向防污阻隔墙结构,属于城市地下水土污染防控技术领域。该竖向防污阻隔墙设置在污染场地的周边,且垂直插入土体中,包括墙体、双层V型HDPE土工膜、防护框及导墙,其中,墙体自上而下由多层不同复合改性膨润土掺量的复合改性膨润土层组成,且在最上层复合改性膨润土层中掺加剑麻纤维以提高抗裂性能。在墙体浅部基础部分插入双层V型HDPE土工膜,且在墙体底部两侧分别设置多种传感器。该竖向防污阻隔墙结构有效缓解了竖向防污阻隔墙浅部基础薄弱,易形成优势渗流通道,造成竖向墙快速失效的问题。同时,在达到最佳使用效果的前提下,节省了膨润土用量,降低了施工成本。
