Description

A kind of infiltration structure of the waterproof road in road surface
Technical field
This utility model relates to a kind of infiltration structure, particularly to the infiltration structure of the waterproof road in a kind of road surface, belongs to Municipal works field.
Background technology
Along with the development in industrialization city, must increasing of urban transportation vehicle, the visible ray from solar radiation is had Highly permeability, and the long-wave radiation emitting the earth has highly absorbent, can strongly absorb in terrestrial surface radiation is red Outside line, causes global warming to rise, creates greenhouse effect, due to the immoderate exploitation of the mankind and destruction resource, whole world rainfall Amount increases, precipitation is redistributed, extreme weather gets more and more, and glacier and frozen soil melt, sea level rise, and mud-rock flow takes place frequently, Flooding of rivers, urban waterlogging, not only endangers the balance of natural ecosystems, also threatens the living environment of the mankind, water drainage originally Flood drainage system is difficult to meet the sudden heavy rainfall that climate change brings, and usually can cause flooding of rivers because of impeded drainage, lead Cause to have inconvenient traffic, cause the loss of people's life and property, particularly some non-permeable road surfaces, and surface gathered water is the most, then Plus can not discharge in time, surface gathered water usually can be caused to raise, cause the accident accidents such as water inlet in low-rise building resident family, On the contrary, along with modern society's science and technology and economic development and progress, the water consumption of China is in increase progressively, nowadays Hydropenia, these all directly result in original clean water resources and face exhaustion.It has been undisputable fact.Rainwater, Zhong Shui, sea water etc. are non- The exploitation at tradition water source become extremely urgent.To this end, country proposes to build " sponge city ", objective is to promote city To pay the utmost attention to limited rainwater to stay during city's drainage system, pay the utmost attention to more utilize elements draining, build from So stockpile, naturally osmotic, the environment-friendly type sponge city of self-purification, build sponge city follow the preferential principle of the ecology, by nature Approach combines with artificial measures, on the premise of guaranteeing municipal drainage prevention waterlogging safety, realizes rainwater to greatest extent in city The accumulation in region, permeate and purify, promoting utilization and the ecological environmental protection of rainwater resource.Building " sponge city " is not to push away Heavily come, replace traditional drainage system, but the one of conventional drainage systems " is lightened the burden " and supplements, farthest play The effect in city itself.In sponge Process of Urban Development, the systematicness of natural precipitation, surface water and groundwater should be planned as a whole, association Assign each link of the water circulation use such as water, draining, and consider its complexity and chronicity.But, for much built up Road is fluid-tight mostly, tremendous economic will be brought to lose if removing to rebuild.So can carry out either with or without a kind of method Transformation, the ability making fluid-tight road possess infiltration is the big problem of faced in current municipal engineering construction.
Summary of the invention
For non-porous pavement impeded drainage, accumulation of rainwater, can frequently result in and have inconvenient traffic, in low-rise building resident family Water inlet or generation accident accident etc., bring the problems such as loss in various degree even can to people's life and property, and this practicality is new Type provides the infiltration structure of the waterproof road in a kind of road surface, its objective is to improve road seepage velocity and infiltration total amount, reduces road Area water, prevents the disaster that road hydrops the most freely brings, and improves the self-restraint of subsoil water, reduces improvement cost, saves construction cost.
The technical solution of the utility model is: the infiltration structure of the waterproof road in a kind of road surface, and described infiltration structure includes What periphery offered water seepage hole is multiple soakaway trench, and one end of multiple soakaway trench is provided with infiltration ditch, the mouth of pipe of multiple soakaway trench Water seepage hole aperture is provided with filter screen, and multiple soakaway trench are arranged on the lower section of road rammed earth layer, infiltration ditch be arranged on greenbelt or Under footpath, the infiltration mouth of pipe is arranged on bottom pipe infiltration ditch, and infiltration ditch is backfilled with descending stone or sand from bottom to top, Top layer is provided with planting soil and greenbelt or cement brick, and infiltration ditch communicates with driveway road surface edge, and infiltration ditch water inlet is high Degree, less than roadside water inlet height, infiltration ditch is provided with overfall, and overfall connects with storm sewer;
Preferably, described soakaway trench is cast iron, rigid plastics, steel pipe or pipe of cement, and the soakaway trench one end less than 10cm is Wedge structure;
Preferably, described roadside water inlet is breach or grid curb;
Preferably, described infiltration ditch is backfilled with boulder bed, permeable building block layer, plantation soil layer the most successively;
Preferably, described infiltration ditch is backfilled with gravel layer or boulder bed, graded broken stone layer, coarse sand the most successively Layer, plantation soil layer;
