Anti-seepage wall structure and cofferdam anti-seepage construction method
The invention discloses an anti-seepage wall structure and a cofferdam anti-seepage construction method.The construction method comprises the following steps that (1) a first anti-seepage wall is formed in a first area and a second area of a construction area through the TRD technology, and a plurality of embedded pipes are installed in the first area; and (2) the embedded pipe is used for drilling along with the pipe to form a hole, the hole is filled with mud, then the follow-up sleeve is pulled out, and a second diaphragm wall and a third diaphragm wall are formed in the second area and the third area through the high-pressure jet grouting method. The anti-seepage wall structure comprises a first anti-seepage wall, a second anti-seepage wall and a third anti-seepage wall which are sequentially arranged from top to bottom in the vertical direction, the first anti-seepage wall is formed through the TRD technology, the second anti-seepage wall is formed through the TRD technology and a high-pressure jet grouting method, and the third anti-seepage wall is formed through the high-pressure jet grouting method. According to the method, the construction problem of the TRD technology in the deep gravel-cobble stratum with the depth of 40 m or above is solved, and the construction progress and the safety flood control requirement are guaranteed.
本发明公开了一种防渗墙结构和围堰防渗施工方法，施工方法包括以下步骤：1)在施工区域的第一区域和第二区域采用TRD工艺形成第一防渗墙，将多个预埋管安装在第一区域；2)利用预埋管跟管钻进成孔，孔内注满泥浆，后拔出跟进套管，在第二区域和第三区域进行高压旋喷灌浆法形成第二防渗墙和第三防渗墙。防渗墙结构包括沿竖直方向自上而下依次设置的第一防渗墙第二防渗墙和第三防渗墙，所述第一防渗墙采用TRD工艺形成，所述第二防渗墙采用TRD工艺和高压旋喷灌浆法形成，所述第三防渗墙采用高压旋喷灌浆法形成。本发明解决了TRD工艺在40m以上深度深厚卵砾石地层施工难题，又保证施工进度和安全度汛要求。
