Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing.

[0020] Such as figure 1 As shown, the dam anti-seepage and water-stop structure includes seam-wise water-stop parts 2 arranged at the transverse joints between the dam body sections 11, and the seam-wise water-stop parts 2 are provided with at least one separate water-stop part 3. Among them, the partition water stop 3 can divide the seam water stop 2 into multiple water stop sections, thereby avoiding seepage around, and facilitates detection and timely and efficient finding of leakage locations; the partition water stop 3 can be tilted Or set it horizontally, subject to the ability to cut off the seam water stop 2; usually, in order to facilitate later leakage monitoring and reduce the monitoring workload, 2 to 5 roads are installed on the seam water stop 2 within every 100m elevation range of the dam Divide the water stop part 3; when there are more than two separate w...

Abstract

The invention discloses a dam by-pass seepage preventing water stop structure. By means of the dam by-pass seepage preventing water stop structure, the problem of by-pass seepage of a water stop part at a transverse joint part due to constructional deficiencies and the like is solved. The dam by-pass seepage preventing water stop structure comprises an along-joint water stop part in the position, inside a dam body section, of the transverse joint part, and the along-joint water stop part is provided with at least one separation water stop part. The along-joint water stop part is divided into a plurality of water stop section parts through the separation water stop parts, communicating of constructional deficiency parts which are randomly distributed is cut off, and by-pass seepage of the water stop part at the transverse joint part is avoided; accordingly, the water stop seepage preventing function of the dam is improved remarkably, and it is beneficial to find out the deficiency parts, so that the deficiency processing measure is targeted.

Description

technical field [0001] The invention belongs to the field of water conservancy and hydropower engineering, and in particular relates to a dam anti-seepage and water-stopping structure. Background technique [0002] The development of water energy resources is one of the important energy strategic development guidelines in our country. As a renewable and clean energy, hydropower plays an important role in the national economy. As a common dam structure, concrete dams are widely used in hydropower engineering construction. Concrete dam seepage control generally includes dam body seepage control and foundation seepage control. Among them, the anti-seepage of the dam body not only depends on the anti-seepage performance of the concrete itself, but also includes the anti-seepage of the transverse joints between the dam body sections, the anti-seepage between the foundation of the dam slope section and the dam body; The anti-seepage curtain is set up below. [0003] Transverse ...
