Description

A New Structure Grass Planting Brick Produced Using Recycled Aggregate

technical field

The invention relates to the field of building materials and the technical field of grass-planting bricks, in particular to a new-structure grass-planting brick produced by using recycled aggregates.

Background technique

Grass planting bricks are made of high-quality materials such as concrete, river sand, and pigments, which are vibrated by a high-pressure brick machine. Grass planting bricks have strong compression resistance, good stability when laid on the ground, wide green area, and can withstand the rolling of pedestrians and vehicles without being easily damaged. It can not only facilitate people's travel, but also increase urban Green area, thereby improving the air. Grass planting bricks turn the grass planting area into a load-bearing surface, suitable for parking lots, sidewalks, access passages, fire exits, golf courses, roof gardens and slopes, slope reinforcement and embankment, and are widely used. However, the existing grass-planting bricks have a single structure and generally have the problem of unstable brick surfaces, and the feet feel uncomfortable when walking. Therefore the development of new grass-planting bricks has very practical and far-reaching significance.

Today's urban construction is full of hardened roads, which will be flooded every time it rains, and droughts and floods will turn sharply. Therefore, it is imminent to build a sponge city and improve the urban drainage system. Priority should be given to retaining limited rainwater and more use of natural forces to drain water, so as to build a sponge city with natural storage, natural infiltration, and natural purification. The invention can simultaneously reduce urban ground hardening, increase rainwater infiltration area, reduce urban waterlogging risk, absorb water, store water, seep water, purify water when it rains, and "release" the stored water and make use of it when necessary.

Recycled aggregate is produced from construction waste through resource recycling. The production and utilization of recycled aggregate from construction waste is of great significance for saving resources, protecting the environment and realizing the sustainable development of the construction industry.

A circular grass planting hole is arranged in the center of the rectangular parallelepiped brick body, and the circular grass planting hole vertically runs through the rectangular parallelepiped brick body. The circular grass hole is used for planting turf, and the short posts are filled with soil. The cuboid bricks are spliced, and the bottom of the short column is a permeable cushion made of extra-dry hard recycled aggregate.

The cuboid brick body is made of recycled concrete of C15 strength grade. The upper cuboid brick body is cuboid, 200mm long, 200mm wide, and 60mm high. The radius of the circular grass planting hole is 40mm, and the center of the circle coincides with the overall centroid. The short columns are cuboids of the same shape, 50mm long, 50mm wide, and 60mm high, and are attached to the four corners of the upper brick body. The chamfered shape of the inclined triangular prism is a triangular prism, the bottom surface of which is a right triangle with 10mm on both sides, and the height is flush with the column. The brick surface of the cuboid brick body is provided with an anti-slip layer, and there are multiple bumps on the surface. Extra-dry hard recycled aggregate cushion adopts extra-dry hard permeable concrete material. There is also a stable layer between the extra-dry hard recycled aggregate cushion and the cuboid brick body, which is made of permeable concrete, and its components are cement, crushed stone, and cement. The grass planting bricks are symmetrical up and down as a whole.

Preferably, the size of the short column is determined by calculating the flexural and compressive strength.
