Description

TECHNICAL FIELD

[0001] The present application relates to the field of porous concrete prefabricated parts, in particular to a lightweight porous concrete prefabricated part for vegetation and a method for using the same. BACKGROUND

[0002] Porous concrete prefabricated parts are concrete products with a large number of internal pores, which are usually prefabricated in factories and then transported to construction sites for installation. The characteristics are: lightweight: due to the existence of a large number of internal pores, its density is relatively low compared to ordinary concrete, and the weight is lighter, which is convenient for transportation and construction. Good water permeability and air permeability: the pores are interconnected, allowing water and air to freely permeate and circulate in the prefabricated part, which can be used in places that require water and air permeability, such as water-permeable pavement, vegetation protection slope, etc. Good thermal insulation performance: the porous structure has a low thermal conductivity, which can effectively reduce heat transfer, and can be used in thermal insulation parts of buildings. Sound absorption and noise reduction: can absorb and reflect sound waves, reduce noise propagation, suitable for road noise barriers and other engineering. Ecological and environmentally friendly: some porous concrete prefabricated parts can be used for vegetation growth, which can promote ecological balance, and some industrial waste and other waste can be used in the production process to reduce environmental pollution.

[0003] Materials for making porous concrete prefabricated parts: cement: usually uses ordinary portland cement, slag portland cement, etc. The strength grade and performance of cement directly affect the strength and durability of the prefabricated part. Aggregate: including coarse aggregate and fine aggregate. Coarse aggregate commonly used are gravel, pebbles, ceramsite, etc.; fine aggregate is generally natural sand or machine-made sand. In order to improve the porosity, some lightweight and porous aggregates such as polystyrene particles and expanded perlite are also used. Water: used to mix cement and aggregate to form a concrete mixture with certain fluidity, the quality of water should meet the standard for concrete water. Admixtures: according to the needs, water reducing agent, air entraining agent, retarder, early strength agent and other admixtures can be added to improve the workability and physical and mechanical properties of concrete. For example, water reducing agent can reduce water consumption and improve the strength and durability of concrete; air entraining agent can introduce small air bubbles to increase the porosity and frost resistance of concrete.

[0004] The preparation process of the porous concrete prefabricated part is as follows: batching: according to the design requirements, accurately weigh the raw materials such as cement, aggregate, water and additive, and mix them according to a certain proportion. Stirring: add the ingredients into the mixer and stir thoroughly to make the cement paste uniformly cover the surface of the aggregate, forming a concrete mixture with good workability. Forming: pour the stirred concrete mixture into the prefabricated mold and compact it by vibration, pressing and other methods. For some complex-shaped prefabricated parts, special processes such as vacuum forming and centrifugal forming can also be used. Curing: the prefabricated part after forming needs to be cured in suitable environmental conditions to ensure that the cement hydration reaction proceeds fully and to improve the strength and durability of the prefabricated part. The curing methods mainly include natural curing, steam curing, spray curing, etc.

[0005] Application fields of the porous concrete prefabricated part Road engineering: can be used for laying permeable pavement to make rainwater penetrate rapidly into the ground, supplement groundwater, reduce urban waterlogging, and also reduce vehicle driving noise and improve driving safety. Water conservancy engineering: as a slope protection material, it can prevent soil erosion and provide habitat for aquatic plants and animals, promoting ecological restoration; it can also be used for constructing drainage facilities of hydraulic structures such as dams and canals. Building engineering: used for external wall insulation, roof insulation and soundproof wall of buildings, etc., to improve the energy-saving effect and living comfort of buildings; also used as non-load-bearing wall material to reduce the weight of buildings. Landscape greening: make plant-type porous concrete prefabricated parts for greening in parks, squares, communities and other places to provide good conditions for plant growth and beautify the environment.

[0006] For example, the patent with application number 202120948536.1 discloses a sand-free porous concrete insulation panel, which includes an outer frame plate, the inside of which is fixedly installed from bottom to top with a lower insulation plate, a lower reinforcing plate, a sand-free porous concrete plate, an upper reinforcing plate and an upper insulation plate. The inside of the lower reinforcing plate is fixedly installed with a first steel wire mesh, and the inside of the upper reinforcing plate is fixedly installed with a second steel wire mesh. The top of the lower reinforcing plate is fixedly installed with a lower reinforcing block, which is fixedly installed in the bottom of the sand-free porous concrete plate. The bottom of the upper reinforcing plate is fixedly installed with an upper reinforcing block, which is fixedly installed in the top of the sand-free porous concrete plate. This design facilitates better positioning and reinforcement of the sand-free porous concrete plate, increases the stability of the sand-free porous concrete plate, and makes the sand-free porous concrete plate have better insulation effect.

[0007] The patent with application number 202222245512.7 discloses a hard-shell porous concrete block, which comprises an outer assembly, a block assembly and a splicing assembly, the outer assembly comprises a hard shell layer, a fixed layer and a connecting layer, the fixed layer is arranged in the hard shell layer, and the connecting layer is arranged in the fixed layer, the block assembly and the splicing assembly are arranged on the outer assembly, the block assembly comprises a block body, circular holes, circular grooves and rectangular grooves, the block body is arranged in the connecting layer, the circular holes are arranged on the block body in a rectangular manner, the circular grooves are evenly arranged on the block body, and the rectangular grooves are arranged on the top of the block body, and the splicing assembly comprises a splicing block one, a semicircular groove, a splicing block two and a semicircular convex block, and the semicircular groove is arranged on one side of the splicing block one.
