Deep-layer anti-seepage structure and anti-seepage method for underground diaphragm wall joint in sandy soil stratum
The invention discloses a deep-layer anti-seepage structure and anti-seepage method for a sandy soil stratum underground diaphragm wall joint. The deep-layer anti-seepage structure comprises an outer vertical pipe and an inner vertical pipe arranged in the outer vertical pipe. A vertical opening is formed in one side of the outer vertical pipe and can make contact with the left side and the right side of a joint on the side, used for excavating a basement, of the underground diaphragm wall. The outer vertical pipe is provided with a plurality of pressure water inlet groups which are sequentially arranged from top to bottom, each pressure water inlet group comprises at least three pressure water inlets which are circumferentially distributed along the cross section of the outer vertical pipe, and a leakage water pipe is arranged between each pressure water inlet and the inner vertical pipe; the method has the advantages that leakage can be effectively prevented from occurring at the joint of the underground diaphragm wall, and piping is avoided.
本发明公开了一种砂土地层地下连续墙接缝的深层防渗漏结构及防渗漏方法，包括外竖管，设于外竖管中的内竖管；外竖管一侧设有竖向开口，竖向开口可与地下连续墙的用于开挖地下室的一侧的接缝左侧和接缝右侧接触；外竖管上设有由上至下依次排列的若干个压力进水口组，所述压力进水孔组包括至少3个沿外竖管的横截面呈圆周分布的压力进水孔，每个压力进水孔与内竖管之间均设有外泄水管；本发明具有可有效防止渗漏在地下连续墙的接缝处发生，避免了管涌的发生的特点。
