Drainage type pavement composite structure

Abstract

The invention relates to a drainage and seepage type felting composite structure. The seepage type felting composite structure comprises a beam-slab felting structure, a permeable PC substrate, a U-shaped ecological water draining and collecting ditch, and a seepage and drainage pipe, wherein the beam-slab felting structure is assembled into a side pavement or a motorized vehicle lane; the permeable PC substrate and the beam-slab felting structure are combined into a motor vehicle lane or a square and have a load effect. The U-shaped ecological water draining and collecting ditch is installed at one side or two sides of the motor vehicle lane or the square; the drainage and seepage pipe comprises a transverse PC pipe and a vertical PC pipe; the transverse PC pipe is communicated with the U-shaped ecological water draining and collecting ditch; and the vertical PC pipe is communicated with the transverse PC pipe. The drainage and seepage type felting composite structure is permeable and breathable, can carry out earth surface heat exchange easily, can recycle rainwater effectively, reduces an urban heat island effect, is suitable for eco-environment protection, is simple in structure, and is simple to construct.

Description

technical field [0001] The invention relates to a pavement structure in the field of roads, in particular to a combined pavement structure for drainage of seepage Background technique [0002] The traditional pavement structure of roads and squares is composed of base, surface and cushion, all of which require on-site construction machinery to pave, roll, and lay the base and surface. There are many on-site construction procedures, and the operating procedures of each process are complicated. , the biggest disadvantage is that it is impermeable, airtight, and difficult for surface heat exchange. Since the 1990s, the use of permeable materials to replace traditional materials for pavement has been widely used in urban construction in developed countries. At present, domestic research on material-based permeable pavements focuses on permeable brick pavements and permeable concrete pavements.

[0002] The traditional pavement structure of roads and squares is composed of base, surface and cushion, all of which require on-site construction machinery to pave, roll, and lay the base and surface. There are many on-site construction procedures, and the operating procedures of each process are complicated. , the biggest disadvantage is that it is impermeable, airtight, and difficult for surface heat exchange.

Since the 1990s, the use of permeable materials to replace traditional materials for pavement has been widely used in urban construction in developed countries. At present, domestic research on material-based permeable pavements focuses on permeable brick pavements and permeable concrete pavements. However, due to cost, There are some difficult bottlenecks in construction technology, strength and maintenance, and it is still difficult to promote it in a large area

However, most of the current rainwater drainage pipes are impermeable U-PVC double-wall corrugated pipes that can only drain water and cannot seep water.

[0004] The current research in foreign developed countries mainly focuses on the collection and reuse of rainwater, but this system takes up a lot of space and requires a lot of investment, so it is difficult to promote it in China

The traditional drainage method hopes that the water will be discharged into the municipal pipe network or the drainage ditch on the roadside as soon as possible, and the function of the drainage ditch is mainly to drain water, and it cannot collect water for use.
