A structure integrating anti-seepage membrane anchoring, flood interception and traffic

Abstract

The invention discloses a structure integrating anti-seepage film anchoring, flood interception and passage. The structure comprises an anti-seepage film system, an anchoring furrow, a flood interception furrow and a maintaining channel. The flood interception furrow is located in the anchoring furrow, and the anchoring furrow is composed of an anchoring furrow base plate and an anchoring furrow wall. The flood interception furrow is composed of a flood interception furrow base plate and a flood interception furrow wall. Part of the anti-seepage film system is located between the anchoring furrow base plate and the flood interception furrow base plate and between the anchoring furrow wall and the flood interception furrow wall, and another part of the anti-seepage film system extends into a backfilling reservoir area. A concrete pressure top is poured on the anti-seepage film system positioned on the side, close to the reservoir area, of the flood interception furrow to serve as the maintaining channel, and a protective handrail is arranged on the outer side of the maintaining channel. The mode of integrated stage construction of the anchoring furrow, the flood interception furrow and the maintaining channel is utilized, so that the anti-seepage film system can be anchored; the arrangement of the flood interception furrow is finished, a reliable drainage system can be formed as early as possible, reservoir area slope runoff is avoided, the compaction problem of backfill sections on the two sides of the anchoring furrow is solved, and the risk of damage to an anti-seepage film caused by flood interception furrow construction is alleviated.

Description

technical field [0001] The invention belongs to the field of anti-seepage engineering construction, and in particular relates to a staged construction structure integrating anti-seepage membrane anchoring, flood interception and passage. Background technique [0002] In environmental protection projects such as domestic waste landfills and industrial solid waste storage yards, according to relevant requirements, anchoring ditches for anti-seepage membrane anchoring systems and flood intercepting ditches for rainwater collection and drainage systems must be installed in landfills and solid waste storage yards. In order to prevent the anti-seepage membrane from sliding naturally under the action of its own weight, and at the same time prevent rainwater from entering the reservoir area, realize the diversion of cleaning and sewage, thereby reducing the amount of leachate. [0003] Although the existing combined construction technology of anti-seepage membrane anchor ditch and f...

Problems solved by technology

However, in actual construction, the storage yard is mostly in the valley area. After the anchor ditch is excavated, it is difficult to form the anchor platform and the anchor ditch on the top of the warehouse regularly. Finally, the construction of flood intercepting ditch is easy to damage the membrane, and it is impossible to use machinery to backfill and compact the anchor platform, anchor ditch and flood intercepting ditch; in addition, a complete drainage system cannot be formed as soon as possible, and the slope is easily washed by rainwater; It is difficult to fix the anti-seepage membrane in the soil anchoring ditch before the construction of the flood intercepting ditch; during the construction of the flood intercepting ditch, the anti-seepage membrane is easily damaged due to the uneven base surface of the anchor ditch and uneven bearing capacity, and the construction quality It is difficult to be guaranteed; when maintaining structures and facilities on high and steep slopes, no special passage has been set up, and there is a lack of safety protection
