Abstract

The utility model relates to a permeable rainwater drainage pipe which comprises a permeable drainage pipe and a filter layer filled outside the drainage pipe, wherein the permeable drainage pipe is made of a sand-free concrete water permeable pipe, and the pipe diameter and the pipeline concrete strength can be determined through calculation according to the water flow and the bearing load; and the filter layer outside the drainage pipe is a grading sand filling material. After rain falls to ground, rainwater is drained into the permeable rainwater drainage pipe through a rainwater collecting well, a part of rainwater can permeate out of the pipe under the action of gravity and pressure inside the pipeline and directly seep into soil through the filter layer, and excessive water can be drained into the river way through a pipe network. Urban rainwater can directly seep into underground to supplement underground water, and the underground water ecological environment is recovered. Meanwhile, various purposes of lowering drainage water amount of urban flood, reducing flood disasters, lowering investment to the rainwater drainage system and the like can be realized.

Description

A kind of infiltration type rain-water drainage pipe
Affiliated technical field
The utility model belongs to a kind of infiltration type rain-water drainage pipe unit.
Background technology
Water circulation under the nature; Begin by natural rainfall; The back part that falls earthward is gone into to be seeped into soil and is formed underground water; The precipitation that can not in time infiltrate forms surface flow and imports the river course, returns atmosphere through modes such as evaporation from land, plant transpirations then, forms the natural water circulating system of a closure.Along with the Rapid Expansion in city, owing to reasons such as road surface sclerosis, building construction, the waterproof area in ground increases year by year in recent years, and precipitation can not get and oozes at present.The runoff coefficient and the run-off that are formed by rainfall on the one hand can corresponding increase very easily form the city flood; City underground water can not get good supply on the other hand, causes groundwater table to adopt to mend unbalance, and groundwater mining is serious.At present, the part city on the sidewalk, zones such as city square, park adopt modes such as permeable concrete ground, pervious floor tile ground to strengthen precipitation infiltration, have obtained certain effect.But receive reasons such as the seepy material bearing load is generally lower, resistance to freezing and thawing is relatively poor, this technology popularization receives very big restriction.
Summary of the invention
The utility model provides a kind of infiltration type rain-water drainage pipe.
The utility model solves the technical scheme that its technical problem adopted: infiltration type rain-water drainage pipe comprises filtering layer two parts composition that the infiltration type gutter is outside with being filled in gutter.
Described infiltration type rain-water drainage pipe, the infiltration type gutter adopts the non-fine concrete water-permeable pipe, and caliber and pipeline coagulation soil intensity can be calculated definite according to water flow and bearing load; At north cold area, the drainage pipe depth of burying will be below antifreeze line.
Described infiltration type rain-water drainage pipe, the outside filtering layer of gutter adopts graded sand and stone to fill, and the aggregate grading ratio is looked outside soil class and is decided, and can be used in combination with gutter sand foundation pad, and the outside filtrate thickness of filling of gutter is not less than 30cm.
After precipitation falls earthward, collect well array through rainwater and go into infiltration type rain-water drainage pipe, a part of rainwater oozes out outside the pipe under gravity and manifold pressure effect, and directly into being seeped in the soil, the unnecessary water yield enters the river course through pipe network when filtration beds.
The beneficial effect of the utility model is, through the utility model design, realized that urban rainwater directly infiltrates underground additional underground water, recovers the underground water ecological environment; Because a part of water yield is directly infiltrated, alleviate the city flood simultaneously, reduced the investment of drainage system against rain.Infiltration type rain-water drainage pipe is embedded in the soil layer below the antifreeze line, has can bear bigger ground load, do not receive freeze injury to influence, save plurality of advantages such as construction investment, easy construction, has very high promotional value.
Description of drawings:
Fig. 1 is the structural principle sketch map of the utility model.
1. infiltration type gutters, 2. filtering layer, 3. natural soils among the figure.
The specific embodiment
In Fig. 1; After precipitation falls earthward, collect well array through rainwater and go into infiltration type gutter 1, because the material of gutter 1 is a kind of permeable non-fine concrete; A part of rainwater wherein oozes out outside the pipe under gravity and manifold pressure effect; Directly into being seeped in the natural soils 3, the good grating of filtering layer sandstone can effectively prevent to permeate current to the structural damage of original natural soils layer simultaneously when passing through the graded sand and stone filtering layer 2 of water permeability, guarantees the stability of basic unit's soil body; The unnecessary water yield can enter the water logging control river course through pipe network.
