Method for constructing ventilating permeable ecological concrete water-storage side slope

Abstract

The invention relates to a constructing method of aerating water penetration ecology concrete side slope. It sets an aerating water penetration ecology concrete layer constructed by graininess aggregate, concrete and the continuous clearance on the water storing side slope piling up by earth material. It has good reverse filtering effect and could effectively decrease the margin height of the water storing side slope.

Description

technical field [0001] The invention relates to a construction method of side slopes in contact with water such as reservoirs, river dams and the like piled up by natural materials such as soil, sand, rocks, etc., and specifically refers to a construction method of air-permeable ecological concrete side slopes. Background technique [0002] The most common slope protection technologies used on the side slopes of reservoirs, river embankments, etc. mainly include: riprap slopes, masonry stones, full-slope cast-in-place concrete slabs, and precast concrete blocks. But no matter what kind of technology, strictly speaking, it is to cover the sand and gravel layer on the side slope of the pile of soil first, so as to play the role of the filter layer, and then use the filter layer that does not have ventilation itself on the filter layer. Water-permeable riprap, masonry blocks, cast-in-place concrete slabs or prefabricated lattice concrete blocks and other related technologies ar...

Problems solved by technology

However, the resulting consequence is that waves will violently intrude along the vent holes and gaps, so that the original slope soil material is continuously eroded by waves; at the same time, due to the rapid change of water level, the soil pile The phenomenon of being sucked out along the drainage holes and gaps will cause a series of problems such as the loss of soil particles and the washing of the slope.

Especially for the water storage side slopes of reservoirs, river dams, etc., due to the change of water level, the side slopes of reservoirs and dams are scoured by circulating water. The soil is easy to concentrate in a certain part of the air vent or the gap to be sucked out directly, which further increases the risk of the slope being washed and excavated

Considering this, the existing cast-in-place concrete slab slope protection technology will also pre-lay a certain width of geotextile in the gap, and use its filtration performance and drainage performance to reduce seepage pressure and protect the cushion. However, this geotextile is easy to Failure, need to be replaced regularly, bring trouble to project management and maintenance

All in all, the anti-filtration effect of the existing embankment protection technology on the side slope of the reservoir does not meet the requirements of solving the fundamental problem

[0004] In addition, until now, when designing the water storage side slope, it is still necessary to consider the problem that the surplus height of the embankment must be designed to be very large, because when the wave hits the slope, the direction of the wave will change upward along the revetment, The kinetic energy held by the wave will be converted into potential energy, which will inevitably increase the height of the wave's upward climb, so the surplus height of the embankment must be built very large
