Filtration structure for dam

Abstract

The invention discloses a filtration structure for a dam. The filtration structure comprises a water stop block, a dam water collecting and draining ditch and an aggregate filtration layer with holes; the water stop block and the aggregate filtration layer with the holes are fabricated parts; the water stop block is in a horizontally-placed plate shape and is partially embedded in the dam; the dam water collecting and draining ditch is located at the exposed part of the water stop block; the aggregate filtration layer with the holes is located below the water stop block and is fixed on the surface of a back surface of the dam; the upper end of the aggregate filtration layer with the holes abuts against the water stop block; and the water stop block, the dam water collecting and draining ditch and the aggregate filtration layer with the holes extend in the length direction of a dam body and have the length equal to that of the dam body. The filtration structure for the dam is simpler in construction procedure, lower in cost and suitable for use in sudden dangerous situations of the dam, besides, a lot of garbage is consumed while the cost is reduced, the ecological environment is protected, the environment stress is relieved, and the structure has the certain social benefits.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, in particular to a protective building for river banks, dams, waterways or similar projects. Background technique [0002] Most of the existing water conservancy projects in our country have been built for many years, and a large part of them have been in disrepair for a long time, and there are potential safety hazards. Among the many safety hazards, leakage is the main problem, because water seepage will lead to a large loss of water, soil and sediment and damage to the dam body. In order to prevent damage to the dam body caused by leakage, it is necessary to prevent seepage of the dam body. However, the existing anti-seepage project of the dam body requires many processes such as on-site formwork support, maintenance, and disassembly during construction, which requires a large amount of work and a long construction time. When a dangerous situation occurs, the rescue time will be d...

Among the many safety hazards, leakage is the main problem, because water seepage will lead to a large loss of water, soil and sediment and damage to the dam body

In order to prevent damage to the dam body caused by leakage, it is necessary to prevent seepage of the dam body. However, the existing anti-seepage project of the dam body requires many processes such as on-site formwork support, maintenance, and disassembly during construction, which requires a large amount of work and a long construction time. When a dangerous situation occurs, the rescue time will be delayed, and a large amount of building materials will be consumed, resulting in high cost

At the same time, due to the rapid development of urban construction, a large amount of construction waste is produced every year. These construction wastes have not been rationally utilized, not only occupying land but also affecting the sustainable development of the construction industry.
