Compared with the prior art, the beneficial effects of utility model are that:

1. the sponge urban roadbed capable of preventing rainwater accumulation realizes the purpose that rainwater can flow into wells on two sides of a road during heavy rainfall by arranging the water-permeable asphalt pavement curved surface;

2. the sponge urban roadbed capable of preventing rainwater accumulation greatly disperses the pressure of drainage through the arrangement of the water conduit;

3. the utility model provides a pair of prevent sponge city road bed of rainwater waterlogging passes through the setting on permeable stratum, natural grit, natural stone and water permeability asphalt pavement, has realized when meetting the less rainfall of intensity, and the rainwater can be preserved in permeable stratum, natural grit, natural stone and water permeability asphalt pavement to reach long-time moist, reduce road raise dust.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic view of a well lid.

In the figure: the concrete water-permeable asphalt pavement comprises a gravel layer 1, a concrete layer 2, a permeable layer 3, natural gravels 4, natural stones 5, a water well 6, a water conduit 7, reinforcing blocks 8, a well cover 9, a handle 10 and a water-permeable asphalt pavement 11.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the utility model.

Referring to fig. 1 to 2, the utility model provides a technical solution: a sponge urban roadbed for preventing rainwater accumulation comprises a gravel layer 1, a concrete layer 2 is laid above the gravel layer 1, a permeable layer 3 is laid above the concrete layer 2, natural gravels 4 are laid on the permeable layer 3, natural gravels 5 are laid above the natural gravels 4, a permeable asphalt pavement 11 is laid on the natural gravels 5, a well cover 9 is arranged on the permeable asphalt pavement 11, the well cover 9 covers a well 6, the well 6 penetrates through the concrete layer 2, the permeable layer 3, the natural gravels 4, the natural gravels 5 and the permeable asphalt pavement 11, two groups of water wells 6 are symmetrically arranged about the perpendicular line of the permeable asphalt pavement 11, four groups of guide pipes are arranged on one side of each water well 6, a first guide pipe, a second guide pipe, a third guide pipe and a fourth guide pipe are sequentially arranged from bottom to top, different numbers of guide pipes are used according to strong rainfall with different strengths, the strength of the strong rainfall can be divided into first-level strong rainfall, second-level heavy rainfall, third-level heavy rainfall and fourth-level heavy rainfall), the diversion pipe is communicated with the diversion pipe 7, and seven groups of reinforcing blocks 8 are arranged on the other side of the well 6.

One side of well lid 9 articulates on well 6, and the upper surface of well lid 9 is provided with handle 10, and one side of handle 10 articulates on well lid 9.

The water-permeable asphalt pavement 11 is set to a curved surface.

Well 6 and ground slope 80, and the import department of well 6 sets up to the funnel mouth type, increases the bore and increases the speed that the water yield got into well 6 in proper order.
