Plant growing type porous concrete ball shape block

Abstract

The plant growing ball shaped porous concrete block is one prefabricated member comprising four parts with spherical cap top and truncated cone bottom arranged symmetrically about the central conic hole. The block is made of the material comprising cement, crushed stone, mineral additive and high performance water reducing agent, and the making process includes stirring in stirrer, and forming through pressing, vibrating or pounding. It has high porosity, high strength and high erosion resistance, and owing to its good water penetrating and air permeability, some plant with proper root system can grow therein.

Description

technical field [0001] The invention is a prefabricated part used in civil engineering, transportation and water conservancy engineering, which belongs to the category of civil engineering materials. [0002] technology field. Background technique [0003] In the construction of transportation and water conservancy projects, the current revetment and road slope protection technologies mainly use ordinary concrete or ordinary concrete blocks for pavement, which will destroy the original regional ecological environment such as soil and vegetation in nature, thereby affecting the area. Plant and animal growth. In some occasions, lattice concrete blocks are used to fill the square holes of the lattice blocks with soil and sow grass seeds, but this technology is not suitable for revetments where the water level changes. [0004] The reason why plants can grow in the soil is that the soil has a high porosity (25--30%), and the soil has air permeability...

Problems solved by technology

[0003] In the construction of transportation and water conservancy projects, the current revetment and road slope protection technologies mainly use ordinary concrete or ordinary concrete blocks for pavement, which will destroy the original regional ecological environment such as soil and vegetation in nature, thereby affecting the area. growth of plants and animals

In some occasions, lattice concrete blocks are used to fill the square holes of the lattice blocks with soil and sow grass seeds, but this technology is not suitable for revetments where the water level changes

[0004] The reason why plants can grow in the soil is that the soil has a high porosity (25--30%), and the soil has air permeability and water retention, and a suitable pH can provide the space and necessary nutrients for plant growth. , but the soil strength is low and the erosion resistance is weak, which is not conducive to the stability of revetment or slope revetment
