Biologically-active porous coarse-aggregate ecological bank-protecting matrix engineering material

Abstract

The invention discloses a biologically-active porous coarse-aggregate ecological bank-protecting matrix engineering material, comprising coarse aggregate, a binding material and a filling material, wherein the coarse aggregate is castaway slag; the binding material is a mixture of C60-or-above high-strength cement, sand, an additive and a binder; and the filling material is a mixture of soil, activated sludge, a water-retaining agent and fertilizer. The coarse aggregate and the binding material are mixed and then coagulated and molded with a mold so as to form a porous ecological bank-protecting matrix engineering material with n rhombic hollowed-out structures, and the filling material is added into pores and/or the rhombic hollowed-out structures. The ecological bank-protecting matrix engineering material designed in the invention can maintain substance and energy exchange among riverbanks, water bodies and natural environment, retains the water and soil of riverbanks, improve ecological vitality in waterfronts and river bottoms and realizes environmental protection ecology and landscape optimization.

Description

technical field [0001] The invention belongs to the technical field of waste recycling and ecological restoration, and in particular relates to a bioactive porous coarse aggregate ecological revetment matrix engineering material. Background technique [0002] The urban waterfront environment has unparalleled landscape characteristics, which can provide space for human leisure and entertainment and improve the quality of the surrounding environment. Both the waterfront area and the bottom of the river must use bank revetment materials. Traditional bank revetment materials mostly use hard materials such as concrete and stones with small porosity, which lack protection for wetland plants and aquatic animals and plants. These traditional materials make The amount of vegetation has been greatly reduced, leading to the destruction of the local water ecological environment, and the groundwater resources cannot be effectively replenished, which completely deviates from the developme...
