Abstract

The utility model discloses a water containing road surface capable of solving waterlogging. A water containing layer and a macadam roadbed are paved on a natural soil layer in sequence. A layer of supporting net made of plastic films is arranged on the macadam roadbed, a supporting net frame is arranged on the supporting net, a plurality of conic drainage pipes are distributed in the supporting net frame evenly, fixedly and vertically, and large openings of the conic drainage pipes face downwards. Supporting net holes positioned under the large openings of the conic drainage pipes are communicated with the macadam roadbed. A concrete reinforcement layer is poured in the supporting net frame to the flat surface of upper pipe openings of the conic drainage pipes, the road surface is poured on the concrete reinforcement layer, and then a stratified structure is formed. By means of the conic hollow plastic pipes, rain water can be guided into the macadam water containing layer under the conic hollow plastic pipes. Furthermore, the conic hollow plastic pipes serve as channels of moisture evaporating upwards in sunny days. The water containing road surface can naturally evacuate rain water caused by heavy rain by storing redundant rain water, so that the pressure of a rain water drainage system is greatly relieved, and waterlogging caused by city waterlogging due to heavy rain is avoided.

Description

A kind of culvert water route face that solves ponding

Technical field

The utility model provides a kind of culvert water route face that solves ponding, is to the improvement of existing road structure, belongs to the pavement construction technical field.

Background technology

At present urban pavement construction all is to roll by roadbed, covers tabia and rolls stone flour or microlith laying levelling, concreting or pitch.Whole road surface all is fluid-tight and airtight.In case heavy rain is arranged, assemble rapidly because the road surface is waterproof, in case surpass the drainability of drainage system against rain.Will form the city waterlogging.Make simultaneously the soil under the road surface destroy the ecological environment of soil under the road surface with naturally completely cutting off.

Summary of the invention

The utility model discloses a kind of culvert water route face that solves ponding, has solved the problem that traditional road surface hydrophobicity is poor, ponding affects traffic.

The utility model provides a kind of culvert water route face that solves ponding, and solution is as follows:

Order is equipped with and contains water layer, rubble roadbed on the natural soils layer; Cover the supporting network that layer of plastic film is made on the rubble roadbed; Supporting network is provided with the support rack, and even stationary distribution has some taper drain pipes in the support rack, and the taper drain pipe is vertically placed, and large mouthful downwards; The supporting network perforate that is positioned under the large mouth of taper drain pipe is communicated with the rubble roadbed; Build the concrete strengthening layer to the upper orifice plane of taper drain pipe in supporting rack, the road surface is built and is consisted of layer structure on it.

The utility model is contained water route face laying first floor and is adopted the uniform hollow plastic sebific duct of countless prefabricated plastics racks as pillar, then tank enters cement concrete, the hollow plastic sebific duct becomes pore and the rainwater pod apertures on earth's surface, and layer of concrete is enough to carry the weight of urban civilization; Second layer macadam on average disperses load-bearing pressure again, allows simultaneously rainwater infiltrate, filter, contain; The 3rd layer is pressed into natural soils for coarse sands layer carrying macadam and slows down rainwater to the quick infiltration of soil; The 4th layer is natural soils, after soil is inhaled saturating rain water, and the self-restraint belowground ecosystem.

Containing the water route face is that pore is punched in the cement world that the underfooting is very hard.Such city in the face of Severe rainstorm by leachy road surface with the rainwater water conservancy diversion under the road surface the culvert water layer so that be penetrated into natural soils, thereby it is underground to receive rainwater ice and snow to enter, and stores, avoids city ponding formation waterlogging.Experimental data shows, contains the water route face, and the permeability rate that can bear is one hour 200mm, and instantaneous heavy rain is below 200mm, and ponding does not have yet, and the moisture storage capacity of underground culvert water layer just is enough to hold.The utility model also is improved the urban heat land effect effect.Rainy day is accumulated in the rainwater under the road surface, and weather clears up by the time, steam volatilization, again the reduction city temperature of nature.Can reduce CO2 emission because reduce using the cooling systems such as air-conditioning, if a medium-sized city underground storage a large amount of rainwater, 3 degree of approximately can lowering the temperature summer equal to save 1,000,000,000 degree electricity consumptions nearly, avoid 600,000 tons of CO2 emissions.Soil under the road surface has had moisture simultaneously, and thereby interchange of air has been improved the ecological environment of soil under the road surface, the underground, the root of plant, the just fine growth of energy of toy in the soil and microorganism catches the carbon dioxide on the road surface, as the nutrient of self, then ozone is fed back to the city, the circulation of the Nature can allow the city give the breathing of oneself for change again.

Good effect of the present utility model is: adoptRubble below the tapered hollow plastic pipe can import rainwater is contained water layer, and fine day is the upwards passage of evaporation of steam.Containing the water route face can be by storing unnecessary rainwater, the evacuation heavy rain of nature.Thereby the pressure that alleviates greatly urban rainwater drainage system can avoid the city to form city ponding and then form waterlogging because of heavy rain.
