Problems solved by technology

[0002] With the continuous acceleration of urbanization and rural modernization, large-scale road hardening and square construction have caused a large increase in impermeable areas. Therefore, when it rains, it is mainly relying on the drainage ditch outside the concrete for drainage, which has low drainage efficiency. , has brought a series of problems that affect the environment and social development, such as increasing the burden of flood control and drainage in urban and rural residential areas, and causing traffic safety problems caused by road accumulation, etc.
[0003] Therefore, there is an urgent need for permeable permeable concrete structures to solve the problem of poor drainage of traditional pavements.

Embodiment 1

[0030] The present embodiment also provides a process for preparing a water-permeable concrete structure, comprising the following steps:

[0031] Step 1: After the two drainage grooves 8 are placed stably, the soil is laid on the periphery of the drainage grooves 8 to form a soil layer 1, and four slopes inclined 5° toward the drainage grooves 8 are arranged on the top of the soil layer 1 and then compacted;

[0032] Step 2: Lay anti-seepage geotextile 2 on top of soil layer 1;

[0033] Step 3: Lay the gravel layer 3 on the slope between the soil layer 1 and the drainage channel 8 and level it so that the soil layer 1 and the gravel layer 3 and the top of the drainage channel 8 are all at the same level;

[0034] Step 4: After the permeable plate 6 is covered on the top of the drainage groove 8, and the two ends are supported on the soil layer 1, after continuing to spread the gravel layer 3, a 500kg small road roller is used for vibration compaction;

Abstract

The invention belongs to the technical field of concrete, and provides a water seepage type permeable concrete structure which comprises a concrete layer, a gravel layer and a soil layer which are arranged in the water flow direction, two drainage grooves formed in a spaced mode are buried in the middle of the soil layer, and permeable holes are formed in the side walls of the two drainage grooves. Four slopes inclining towards the side walls of the drainage grooves are arranged at the top of the soil layer, the inclination of the slopes ranges from 3 degrees to 6 degrees, the tops of the two drainage grooves are each covered with a water permeable plate, the two ends of each water permeable plate are further supported on the soil layer, and anti-seepage geotechnical cloth is further arranged between the soil layer and the gravel layer. Glass fiber mesh cloth is laid in the middle of the concrete layer. The two drainage grooves are laid in the soil layer, the effects of concentrating seepage water and draining water can be achieved, in addition, single-walled carbon nanotubes and silicon carbide are added into raw materials of the concrete layer, the gravel layer is arranged between the soil layer and the concrete layer, the overall stability can be improved, and meanwhile the effect of promoting drainage can be achieved.
