Abstract
The utility model provides a concrete slab made of waste concrete, which comprises a base layer, wherein a plurality of placing grooves are arranged above the base layer, and the placing grooves are respectively a drainage layer, a permeable concrete layer and a surface layer from bottom to top; the drainage layer is formed by pressing recycled concrete, and a drainage groove is reserved in the drainage layer; the pervious concrete layer is formed by pressing pervious concrete with large porosity. The concrete slab made of the waste concrete can be transported to the site for laying and connecting after being prefabricated in a factory, and has the advantages of stable product quality, high construction efficiency, convenient connection and convenient later maintenance and replacement; and the recycled concrete is adopted to prepare the base layer and the drainage layer, so that the secondary utilization of the concrete is realized.
Description
Technical Field
The utility model relates to a concrete slab, concretely relates to concrete slab who is made by abandonment concrete.
Background
Along with the development requirement of sponge city construction, the application of pervious concrete to the fields of road surfaces, footpaths, squares and the like is more and more extensive, but at present, the mode of casting pervious concrete in situ or paving pervious concrete bricks is mainly adopted. Before pouring, the construction of a drainage layer is required, and once the drainage layer loses the function, the later maintenance is extremely difficult; in addition, the construction process needs to be implemented by large-scale construction equipment, such as heavy equipment like a concrete transport vehicle, a paver, a compactor and the like. After pouring, long-time maintenance is needed; meanwhile, the construction quality is greatly influenced by field operation conditions and the technical level of constructors; is not beneficial to the later maintenance.
Disclosure of Invention
In order to solve the above problem, the utility model provides a concrete slab who is made by abandonment concrete.
The technical scheme of the utility model is that: a concrete slab made of waste concrete comprises a base layer, wherein a plurality of placing grooves are arranged above the base layer, and the placing grooves are respectively a drainage layer, a permeable concrete layer and a surface layer from bottom to top; the drainage layer is formed by pressing recycled concrete, and a drainage groove is reserved in the drainage layer; the pervious concrete layer is formed by pressing pervious concrete with large porosity.
Furthermore, the thickness of the pervious concrete layer is equal to that of the drainage layer, and the thickness of the surface layer is one half of that of the pervious concrete layer and the drainage layer.
Furthermore, the thickness of the pervious concrete layer is 4-6cm, the thickness of the drainage layer is 4-6cm, and the thickness of the surface layer is 2-3 cm.
Furthermore, the water permeability coefficient of the permeable concrete layer is 4 mm/s.
Furthermore, the drainage grooves are close to the pervious concrete layer, and the adjacent drainage grooves are parallel or communicated.
Furthermore, the side surface of the base layer is provided with a drainage hole at a position corresponding to the drainage groove.
Furthermore, the base layer is formed by pressing recycled concrete.
Advantageous effects
The concrete slab made of the waste concrete can be transported to the site for laying and connecting after being prefabricated in a factory, and has the advantages of stable product quality, high construction efficiency, convenient connection and convenient later maintenance and replacement; and the recycled concrete is adopted to prepare the base layer and the drainage layer, so that the secondary utilization of the concrete is realized.
