Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of water conservancy and hydropower engineering, and specifically relates to an anti-seepage connection structure of a geomembrane and an asphalt concrete panel, which has good anti-seepage performance, long service life, stable and reliable connection, convenient construction and low cost. Background Art
[0002] Asphalt concrete is widely used in various water conservancy and hydropower anti-seepage projects due to its excellent anti-seepage performance and ability to adapt to foundation deformation, among which asphalt concrete panel dam is one of the application forms. However, due to the relatively high cost of asphalt concrete and the relatively complex construction technology, a geomembrane combined with asphalt concrete panel anti-seepage solution is adopted in some projects. However, due to the material property limitations of asphalt concrete and geomembrane and the high standard requirements for anti-seepage in the connection of anti-seepage structures, conventional anchoring, pasting or pressing methods to connect the two anti-seepage materials are prone to form leakage channels, thereby affecting the normal operation of the dam and even endangering the safe operation of the dam, which greatly limits the application of this combined anti-seepage form.
[0003] In the prior art, geomembranes and asphalt concrete panels are usually anchored in two ways: embedded structure and surface physical anchoring. The embedded structure is to directly bury the geomembrane in the asphalt concrete, and cast the geomembrane and asphalt concrete together to form an anchoring sealing structure; while the surface physical anchoring is to lay the geomembrane on the surface of the asphalt concrete, and then use beading, rubber gaskets, bolts, etc. to fix the geomembrane on the surface of the asphalt concrete to form a fixed seal. However, burying the geomembrane in the asphalt concrete will not only form structural seams and weaken the structural strength of the asphalt concrete, but also because the asphalt concrete panel has a small thickness and low modulus, the panel is very easy to break and leak, and the part of the geomembrane buried in the asphalt concrete and the part not buried have different storage environments, resulting in different aging speeds and easy damage near the interface. As for the surface physical anchoring, since the asphalt concrete panel is generally thin and has a low modulus and is soft, the use of bolt anchoring will not only penetrate the panel, but also the screw ring is easy to loosen and damage, which is not conducive to anti-seepage and structural stability. To this end, there is also a method of setting a concrete connecting plate between the geomembrane and the asphalt concrete panel, bonding the geomembrane to the surface of the concrete connecting plate through the SK protective adhesive coating, thereby avoiding the possibility of anchor connection failure through bonding; and the joint part of the geomembrane and the concrete connecting plate adopts a U-shaped folding structure, which can absorb the three-way displacement of the joint part, avoid the geomembrane itself from being stressed and strained, and improve the durability of the geomembrane; and a sliding joint is adopted between the asphalt concrete panel and the concrete connecting plate, so that the joint part can adapt to a certain three-way displacement without leakage. However, the joint structure of the asphalt concrete panel and the geomembrane requires the laying of cushioning material at the U-shaped fold of the geomembrane. Therefore, when the geomembrane is damaged or wrinkled, it is difficult to smooth or replace the geomembrane in time. The cushioning material needs to be removed before the geomembrane can be replaced or smoothed, which increases the construction cost. Utility Model Content
