Earth rock cofferdam anti-seepage construction method combining high-pressure jet grouting and clay core wall
The invention discloses an earth rock cofferdam anti-seepage construction method combining high-pressure jet grouting and a clay core wall. The anti-seepage construction method is characterized by comprising the following steps: (1) filling a dike: filling the dike by adopting a throwing and filling method; (2) heightening an embankment: specifically, after the embankment is closed, filling the two sides of the embankment with a lower-layer cofferdam first, then filling the middle of the lower-layer cofferdam with a lower-layer clay core wall, and forming an earth rock cofferdam bottom layer structure with the thickness of 0.5-2 m through filling to heighten the embankment; (3) carrying out high-pressure jet grouting construction; (4) filling the top layer of the earth rock cofferdam; and (5) carrying out surface protection and foot protection construction. According to the method, the advantages of clay core wall seepage prevention and high-pressure jet grouting seepage prevention are integrated, the construction process is simple and feasible, and it is ensured that the earth rock cofferdam seepage prevention effect meets the requirement for permanent hydraulic structure dry land construction.
本发明公开了一种高喷防渗结合粘土心墙的土石围堰防渗施工方法，其特征在于包括如下步骤：(1)戗堤填筑：采用抛填法进行戗堤填筑；(2)戗堤加高：在戗堤合龙后，先从戗堤两侧填筑下层围堰，之后于下层围堰的中间填筑下层粘土心墙，以填筑形成厚度为0.5～2m的土石围堰底层结构对戗堤加高；(3)高压喷射灌浆施工；(4)土石围堰顶层填筑；(5)护面及护脚施工。本发明方法综合了粘土心墙防渗及高压旋喷防渗的优点，施工工艺简单，切实可行，确保土石围堰防渗效果满足永久水工建筑物干地施工的要求。
