Cast-in-situ invert filter type pervious ecological concrete and method for constructing slope protection thereof

Abstract

The invention discloses cast-in-situ reversed filtering type non-watertight eco-concrete and a construction method for a revetment thereof. The eco-concrete is the composition of grain aggregates and a cement hydrate; the grain aggregates comprise coarse aggregates and thin aggregates, which account for 70 to 85 percent of the total weight of the composition; the cement hydrate is the mixture of Portland cement, water and additive; the doping amount of the cement and the water accounts for 14.5 to 29.5 percent of the total weight of the composition; the additive comprises calcium salt, silicon powder, functional inorganic salt as well as lignosulphonate question mark hydroxycarboxylic acid; and the doping amount of the additive accounts for 0.1 to 0.5 percent of the total weight of the composition. The eco-concrete of the invention can realize cast-in-situ construct, and has higher anti-pressing intensity; moreover, the poriness size and the aperture distribution range can be designed and the controllability is good; the cast-in-situ reversed filtering type non-watertight eco-concrete applied to the fields of revetment protecting and controlling can improve the anti-pressing intensity, the permeable performance and the reversed filtering performance of the concrete revetment and simultaneously has the function of greening vegetation.

Description

technical field

[0001] The invention relates to an ecological concrete and an application thereof, in particular to a cast-in-place reverse filter ecological concrete and a construction method for concrete slope protection applied to slope protection of reservoirs, river dams, mountains and roads. Background technique

[0002] The protection and management of slopes (reservoirs, river embankments, mountains and road slopes, etc.) and the research and development of related new technologies have attracted more and more attention. The traditional slope treatment methods mainly include pouring concrete on site, laying stones or slabs on the filter layer, masonry stones, anchoring of reinforced concrete prestressed frame beams, concrete fences, metal plastic mesh, accumulation of gravel, retaining walls and Anti-slide piles and other methods. These methods are not only time-consuming and labor-intensive but also have a single function, and usually do not have the functions of e...
