Abstract
Concrete road surface water collect structures permeates water, this water collect structures have been laid by lower supreme order on the road surface: bottom load layer, filter layer, upper portion load layer, the concrete topping permeates water, bottom load layer is natural tamp ground, and the filter layer is geotechnological cloth, can filter permeating water, is provided with the recess on the middle part of this filter layer for lay the semipermeability pipeline that catchments, the semipermeability is catchmented the peak of pipeline and is less than the highest level face on bottom load layer. This concrete road surface water collect structures permeates water, can improve the ecological balance between city and the natural environment at simple structure, including alleviateing heat island effect, reducing urban waterlogging, can also collect the rainwater betterly, and the recycle who improves the water resource is rateed, alleviates city water shortage.
Description
Technical field
The utility model relates to a kind of road-face water-collecting structure, especially a kind of pervious concrete pavement water collecting structure.
Background technology
Existing urban road adopts pitch and fluid-tight concrete to carry out paving in a large number, formed and close earth's surface, city " heat island effect " can be aggravated in this earth's surface, disturbance ecology balances, be commonly called as on " death ground ", for improving this situation, some line cities of China are used pervious concrete gradually instead and are carried out paving.
China is the country of a water resource critical shortage, although gross amount of water resources comparatively horn of plenty, water resource is not enough per capita, is one of the country of 13 poor-waters the most in the world.Along with the propelling of urbanization process, shortage of water resources problem is further serious, and present China has more than 400 urban water supply deficiency, more than 110 city serious water shortage.
The monsoon climate of China is remarkable, and attacked by heavy rain, urban waterlogging problem is further serious, causes economic loss, life inconvenience on the one hand, on the other hand because rainwater is mostly via blow-off line excretion, is also to the waste with water resource.
Summary of the invention
Attacked by heavy rain for solving, urban waterlogging problem is further serious, not only cause economic loss, also cause the problem of water resource serious waste simultaneously, the utility model provides a kind of pervious concrete pavement water collecting structure, the ecological homeostasis between city and natural environment can be improved, comprise and alleviate heat island effect, minimizing urban waterlogging, rainwater can also be collected preferably, improve the recovery utilization rate of water resource, alleviate city water shortage.
The utility model solves the technical scheme that its technical problem adopts: pervious concrete pavement water collecting structure, comprising: bottom load layer, filtration beds, upper load layer, pervious concrete surface layer, semi-permeable collecting conduit, road kerb; This water collecting structure is on road surface, order is equipped with from the bottom to top: bottom load layer, filtration beds, upper load layer, pervious concrete surface layer, described bottom load layer is natural compacting foundation, filtration beds is geotextiles, this filtration beds can filter permeable, and the middle part of this filtration beds is provided with groove, for laying semi-permeable collecting conduit, the peak of semi-permeable collecting conduit, lower than the highest level face of bottom load layer, is more conducive to catchmenting.
Described upper load layer adopts particle diameter to be the rubble of 10-40mm, and laying depth is 200mm; Lay pervious concrete surface layer on upper load layer top, laying depth is 150mm.
The raw material of described pervious concrete surface layer comprise cement, aggregate, Admixture and water; Cement selection 42.5R portland cement in embodiment; Coarse aggregate is 5-10mm one-stone grading rubble, bulk density every cubic metre 1513kg, porosity 45.1%; Fines is standard sand; Admixture comprises water reducing agent and cement modifier, and wherein water reducing agent is efficient retarding and water reducing agent, water-reducing rate 25%, and modifier is SJ-601 cement modifier;
In described embodiment, the distribution of pervious concrete surface layer is as follows: cement 316.18kg/m
3, water 91.44kg/m
3, standard sand 88kg/m
3, 5-10mm one-stone grading rubble 1513kg/m
3, efficient retarding and water reducing agent volume is 1.1%, SJ-601 cement modifier volume is 0.13%;
According to above-mentioned distribution, feed intake in order, stir, standard curing records its compressive strength after 28 days be 13.61Mpa, and effective drainage porosity is 21%, has good water permeability.
The combination of described bottom load layer and filtration beds geotextiles can while the bearing load of top, prevents from infiltrating the water of roadbed or underground water because of capillarity to rise, thus better maintains structural stability; Filtration beds geotextiles has good water permeability, and water flow stationary is passed through; First upper load layer can store the infiltration of a part of upper strata, and when oozing the limit under the rainwater infiltration speed of upper load layer exceeds vertical current, more rainwater can be focused on semi-permeable collecting conduit by horizontal flow.Owing to have employed pervious concrete pavement water collecting structure, under the rainwater that oozes supplement urban groundwater, the unnecessary water yield is effectively collected, improve the available water retention capacity in city, alleviate city flood discharge burden, alleviate urban heat land effect, improve city and the natural ecological homeostasis.Pervious concrete pavement water collecting structure solves many difficult problems of urban development, can be widely used in the road pavement in many places such as community, school, business block, square, gardens.
The beneficial effects of the utility model are: this pervious concrete pavement water collecting structure, structure is simple, can improve the ecological homeostasis between city and natural environment, comprise and alleviate heat island effect, minimizing urban waterlogging, rainwater can also be collected preferably, improve the recovery utilization rate of water resource, alleviate city water shortage.
