Water permeability multifunctional concrete and component for sponge urban construction

Abstract

The invention discloses water permeability multifunctional concrete and a component for sponge urban construction. The water permeability multifunctional concrete component for sponge urban construction sequentially comprises a water permeability asphalt layer, a pebble layer, a concrete base layer, a water permeability base layer and a soil base layer from top to bottom. A water drainage pipe is arranged in the concrete base layer. The water permeability asphalt layer is prepared from, by weight, 100-120 parts of pebble, 5-8 parts of cement, 50-80 parts of asphalt, 5-10 parts of a compatibilizer, 5-10 parts of gelatine powder, 0.5-5 parts of macromolecule polymer, 0.5-2.5 parts of a first auxiliary, 0.5-1.5 parts of rare earth, 1-5 parts of a foaming agent and 0.5-1.5 parts of an elastic agent. The asphalt is AH-70 or AH-90 asphalt. The water permeability performance is excellent, the physical performance is excellent, the application region is wide, construction is convenient, underground water can be supplemented, and the certain peak flow reduction and rainwater purification effects are achieved.

Description

technical field [0001] The invention belongs to the field of sponge city construction, in particular to a water-permeable multifunctional concrete and components for sponge city construction. Background technique [0002] Urbanization is a powerful engine to maintain sustained and healthy economic development, a strong support for promoting coordinated regional development, and an inevitable requirement for promoting overall social progress. However, at the same time as rapid urbanization, urban development is also facing enormous environmental and resource pressures, and the urban development model of extended growth has become unsustainable. Therefore, we must adhere to the development path of new urbanization and coordinate the contradiction between urbanization and environmental resource protection in order to achieve sustainable development. Building a sponge city with the functions of natural accumulation, natural infiltration and natural purification is an important ...
