Concrete cap and geomembrane connecting type of diaphragm wall and construction method of concrete cap and geomembrane connecting type
The invention discloses a concrete cap and geomembrane connecting type of a diaphragm wall and a construction method of the concrete cap and geomembrane connecting type. The construction method comprises the steps that the position of the concrete diaphragm wall is determined; the two sides of the position of the concrete diaphragm wall are filled with construction platforms; concrete guide walls are poured on the construction platforms along the two sides of the center line of the concrete diaphragm wall; slotted holes are formed in the concrete guide walls, the concrete diaphragm wall is poured, and the top of the concrete diaphragm wall is flush with the construction platforms; concrete in a chiseling area at the top of one side of the upstream face of the concrete diaphragm wall is chiseled away, and a groove with the right-trapezoid section is formed; the inner bottom wall and the right side wall of the groove are coated with asphalt, and a composite geomembrane is attached to an asphalt layer; the composite geomembrane is anchored to the inner bottom wall of the groove through anchor bolts, and the composite geomembrane on the right side wall in the groove extends upwards to be kept vertical and fixed; and concrete is poured on the two sides of the composite geomembrane to form a concrete cap, and the tail end of the composite geomembrane extends out of the top of the concrete cap. The water stop and seepage prevention effects are good, construction is convenient, and the project investment cost is low.
本发明公开了一种防渗墙混凝土盖帽与土工膜连接型式及其施工方法，包括确定混凝土防渗墙位置；在混凝土防渗墙位置两侧填筑施工平台；在施工平台上沿混凝土防渗墙中心线两侧浇筑混凝土导向墙；在混凝土导向墙内开槽孔，浇筑混凝土防渗墙，其顶部与施工平台齐平；凿除混凝土防渗墙迎水面一侧顶部凿除区的混凝土，形成截面为直角梯形的凹槽；在凹槽内底壁和右侧壁涂刷沥青，并将复合土工膜贴在沥青层上；将复合土工膜用锚栓锚固在凹槽内底壁上，槽内右侧壁的复合土工膜向上延伸，保持竖立，固定；复合土工膜两侧浇筑混凝土形成混凝土盖帽，复合土工膜末端伸出混凝土盖帽顶部。本发明止水、防渗效果好，施工方便，工程投资成本较低。
