Pervious concrete paving system with penetration and drainage guide tubes

A technology of permeable concrete and drainage pipes, which is applied to cohesive pavement paved on site, roads, and the bottom of roads, etc. It can solve the problem that water cannot be quickly drained to surrounding pipes, water accumulates on the surface of permeable cement concrete, and water storage capacity is small. problems, to achieve the effect of reducing road surface water, increasing groundwater recharge, and delaying runoff formation

Embodiment Construction

[0021] Please refer to the attached figure 1 And attached figure 2 As shown, the present invention is a permeable concrete pavement system with a permeable drainage pipe, which consists of a permeable concrete layer 1, a permeable drainage pipe 2, a porous cement stabilized crushed stone base 3, and a graded gravel crushed stone layer 4. The road base layer 5, the rainwater well 6 and the edge stone 7 are composed of several parts.

[0022] Wherein, the road base 5, the graded gravel gravel layer 4, the porous cement stabilized gravel base 3 and the permeable concrete layer 1 are laid sequentially from bottom to top.

[0023] The seepage guide pipe 2 is buried in the permeable concrete layer 1, which extends into the rainwater well 6. When it rains, the rainwater infiltrates into the seepage guide pipe 2 through the permeable concrete layer 1, and partly passes through the seepage guide pipe 2 flows in the rainwater well 6, and the part continues to infiltrate. The permeat...

Abstract

The invention relates to a pervious concrete paving system with penetration and drainage guide tubes. The system comprises a pervious concrete layer, penetration and drainage guide tubes, a porous cement stabilized macadam base layer, a graded gravel macadam layer, a roadbed layer and a catch basin, wherein the roadbed layer, the grading gravel macadam layer, the porous cement stabilized macadam base layer and the pervious concrete layer are paved from bottom to top in sequence; the penetration and drainage guide tubes are buried inside the pervious concrete layer and extend into the catch basin. The pervious concrete paving system with the penetration and drainage guide tubes is simple in structure, can effectively increase the porosity of permeable pavement and improves the rainwater retaining and drainage capability.

Description

【Technical field】 [0001] The invention relates to a permeable pavement system, in particular to a permeable concrete pavement system with permeable drainage pipes, belonging to the technical field of construction engineering. 【Background technique】 [0002] Traditional road paving emphasizes the durability and applicability of the ground, and has strong impermeability. In the process of rainfall and runoff, the natural precipitation is completely blocked from the underground soil and groundwater, which increases the formation of runoff, increases the flood peak flow, and advances the confluence time, causing large areas of water in some areas of the city, seriously affecting the normal operation of the city . Due to the impossibility of infiltration of rainwater and the excessive extraction of urban groundwater, the urban groundwater level has dropped sharply, local ground subsidence, building cracks, and seawater backflow in coastal areas have threatened people's life and ...
