Embodiment Construction
[0035] The present invention will be further described below in conjunction with accompanying drawing:
[0036] figure 1 Shown is the flow chart of the method for improving the reliability of anti-seepage by sealing the dam surface anti-seepage membrane in different regions according to the present invention.
[0037] The method for improving anti-seepage reliability of dam surface anti-seepage membrane partition sealing of the present invention comprises the following steps:
[0038] S1. Preset the dividing line 2 of the dam surface 1 division.
[0039] The lower part of the dam surface 1 is the dam body concrete 7 . Further, as figure 2 As shown, the method of pre-setting the dividing line 2 of the dam surface 1 division is:
[0040] According to the shape and size of the dam surface 1, the dam surface 1 is divided into several geometric figures, and the edges of the geometric figures are the division lines of the dam surface divisions.
[0041] Specifically, the geome...

The invention discloses a method for increasing seepage prevention reliability by sealing a dam surface seepage prevention film partition. The method includes the steps that a dividing line of the damface partition is prearranged; a fastener is mounted along the prearranged dividing line; a seepage prevention film is sprayed on the dam surface; the fastener is disassembled, and a compress part ismounted at the position where the fastener located; the compress part is fixed by the fastener; seepage prevention materials are sprayed on the surface of the fastener and the compress part, and a fastener pressing strip protective film is formed. According to the method, the problem of failure of whole seepage prevention due to the fact that the seepage prevention film is prone to falling off locally or in large area in the prior can be solved, the cost can be saved, the work efficiency can be improved, and the reliability of a seepage prevention body can be enhanced.
Description
technical field [0001] The invention relates to the technical field of water conservancy and hydropower engineering, in particular to a method for sealing the anti-seepage film on a dam surface in sections to improve the reliability of anti-seepage. Background technique [0002] Concrete cracks and dam surface leakage are important diseases of retaining dams. Once leakage occurs on the dam surface, it will not only affect the durability of the dam structure, but also affect the safety of the project and increase the cost of operation and maintenance. Therefore, whether it is a concrete dam or an earth-rock dam, the problem of dam seepage prevention is an important issue in engineering design, construction and operation and maintenance. major key issues in management. Both concrete dams and face rockfill dams use concrete in the upstream surface area of the dam as the anti-seepage body. Specifically, the concrete dam uses concrete itself as the anti-seepage body, and the f...
