Description
Technical field
It the utility model is related to sponge urban construction technical field, and in particular to a kind of room suitable for old Urban re-development
Face rainwater collecting and treating system.
Background technology
Rainwater is the important step in city water cycle and region water circulation system, to adjusting, supplementing regional water, change
Kind ecological environment plays extremely crucial effect.The stage of High-speed Urbanization is at present, with the level of urbanization
Improve and economic fast development, Urban Storm Flood problem of management are particularly important.The planning and designing of China's sewerage system
How urban rainwater is drained and simply relied in traditional concepts such as " the dirty shuntings of rain " by many also only rest on as soon as possible,
The requirement of Modern Urban Development and ecological environmental protection can not be met.
The theory in sponge city has been widely used for Urban Storm Flood management at present, using city as gathering ground, as sponge
Equally, have good " elasticity " adapting to environmental change and tackle natural calamity etc., water suction when rainy, water storage, infiltration,
Water purification, it is necessary to when by the water stored " release " and be used.Sponge the idea of the city is focused on increasing urban runoff rainwater source and subtracted
The rigid constraint of row, by source emission reduction, transfer halfway and realize the benign hydrologic cycle in city with the end measure such as regulate and store, improve pair
The infiltration of runoff rainwater, regulate and store, purify, utilization and discharge capacity.Rainwater catchment system is then the most direct means of source emission reduction,
It is the important measures for realizing rainwater efficiently " store, stagnant, with ".
At present, the municipal drainage system of city tradition is primarily present following shortcoming:
(1) city Permeable stratum area increase, during very heavy rains, flow path surface is big, city planting ductwork flood carrying capacity deficiency, easily
Trigger road flood ponding;
(2) rainwater immersion carries a large amount of house refuses and pollutant on ground, can block municipal pipeline, discharge into water arrives
In natural environment, the pollution of natural water can be aggravated;
(3) a large amount of rainwater are discharged into natural water by city planting ductwork, can aggravate River load, or even trigger life
State environmental disruption;
(4) rainwater resource is caused largely to be lost in, it is impossible to fully to recycle.
Some particularly current old cell Poor construction quality of terrace-bank, Permeable stratum area ratio is high, road surface product easily occurs
Water, the problems such as causing cell waterlogging and rainwater runoff pollution.Therefore, existing old cell rainwater regulating pondage system need to be risen
Level transformation, but the excavation that existing remodeling method needs to carry out old cell large area mostly is regulated and stored with building rainwater-collecting
Pond, considerable influence, and whole upgrading process construction volume can be so generated to former cell ecological environment and cell pattern
Greatly, cost is high, transformation cycle length.Therefore, how a kind of rainwater storage for efficiently, being efficiently applied to old Urban re-development is provided
Collection system turns into the technical barrier of current those skilled in the art solution urgently to be resolved hurrily.

Enough so that rainwater can be pressed into soil stack in perforated drain pipe, finally enter water storage box memory storage from connecting tube.
Water storage box is arranged in the metal framework below carrying platform, and the second overflow pipe 21 and water intaking are provided with water storage box
Mouthfuls 22, the second overflow pipe can automatically be flowed out, avoid internal pressure excessive after rainwater is filled with water storage box;First overflow pipe
It is connected with the second overflow pipe with Storm Sewer Network 4, the rainwater of this part discharge can continue through Storm Sewer Network and drain;The sun shines again after the rain
The water of water storage box can be taken out afterwards for pouring greening or for carwash etc. by intake.
Delay height is provided between the mouth of pipe and filter layer of first overflow pipe, when rainfall is excessive, rainwater can not first
Time permeates, and rainwater, which can be assembled, is trapped in filtering layer surface, and it is the maximum height after rain water-harvesting to be detained height, when reaching this
After height, rainwater can discharge from the first overflow pipe, and the rainwater being detained herein forms certain water level, can so increase biological treatment case
Interior storage capacity, further improve the effect for the slow row that avoids the peak hour.
The setting height of second overflow pipe is equal to or less than the setting height of connecting tube, ensures the normal of biological treatment case
Use, when the second overflow pipe is highly higher than connecting tube, rainwater height highly maintains an equal level with rainwater in water storage box in biological treatment case
It could discharge, equivalent to the height for improving water conservation layer, transition zone is in long period of soaking state, and original structure is destroyed.
Water storage box bottom and biological treatment bottom portion are provided with bearing base 5, are separated with roadbed, avoid the dirt of bottom surface
Dye corrodes water storage box and biological treatment case, protection screen frame is additionally provided with biological treatment case outer surface, protection screen frame can be with holding
