Reservoir dam vertical expansion joint leakage treatment method under non-drainage condition
The invention provides a reservoir dam vertical expansion joint leakage treatment method under the non-drainage condition, and belongs to the technical field of hydraulic engineering. An expansion joint is formed in a dam body, and dam front deposited soil is accumulated on one side of the dam body and covers the bottom of the expansion joint in a buried mode; the method comprises the following steps that S1, hole channels are formed, specifically, the hole channels are formed in the two sides of the expansion joint from top to bottom, and the hole channels are formed from the dam top to the dam bottom; s2, an enclosure seam is constructed; constructing an enclosure seam by adopting an insertion plate, firstly pressing the insertion plate downwards, then pulling out the insertion plate, forming the enclosure seam and forming a grouting injection port at the same time; s3, a barrier wall is constructed, an expansion joint leakage treatment system is formed, and leakage points are blocked; in the step, a barrier wall is formed by adopting a barrier plate and a grouting mode. The construction process is relatively simple, water drainage and excavation are not needed, the construction cost is low, the construction period is short, time and labor are saved, and leakage treatment of the expansion joint can be rapidly achieved.
本发明提出了不放水条件下水库大坝竖向伸缩缝渗漏治理方法，属于水利工程技术领域，其中，坝体上设置有伸缩缝，坝体一侧堆积有坝前淤积土，坝前淤积土将伸缩缝的底部埋覆；该方法包括如下步骤S1：打设孔道：于伸缩缝两侧分别自上而下打设孔道，孔道由坝顶一直开设至坝底处；S2：构造围合缝；采用插板进行围合缝的构造，先下压插板，后拔出插板，形成围合缝同时形成灌浆注入口；S3：构造阻隔墙，形成伸缩缝渗漏治理体系，将渗漏点阻隔；此步骤中采用阻隔板与灌浆的方式形成阻隔墙。本施工工艺相对较为简单，无需放水、开挖，造价低，工期短，省时省力，可快速实现伸缩缝的渗漏治理。
