Description
Technical Field
The invention belongs to the field of urban construction, and particularly relates to a regulation and storage structure for sponge urban road construction.
Background
Sponge city construction is an important concept transformation of city development mode, is an important part of ecological civilization construction, belongs to the embodiment of the mainstream value of ecological civilization, and is the most important factor in source emission reduction. In actual engineering practice, "two rates" of "source emission reduction" are: the two indexes of the total annual runoff control rate and the annual runoff pollution removal rate are the most important.
With the continuous promotion of the construction projects of sponge cities of various test points, the relation between two rates in the construction of the sponge cities is more clear in the industry: the index of the total annual runoff control rate is really important, but finally the pollution control effect of the rainwater runoff is also taken as a target. In a series of measures for sponge city construction, the control of rainwater volume is a way, method or carrier, and the pollution of rainwater runoff is controlled by controlling the rainwater volume. Namely: the total control rate of the annual runoff is a process and a means, the pollution removal rate of the annual runoff is a final effect target to be achieved, and the volume control is one of an effective method and an important way for realizing the pollutant reduction target.
Wanghenliang, li junqi, car wu et al in "a discussion of several problems in the determination of total runoff control target and landing" point out "control" in the term "total runoff total control rate" in the technical guidance of construction of sponge cities "refers to" total runoff control ", i.e. including the total runoff pollutant amount and the runoff volume. For biological retention facilities with bottom outflow, a delayed regulation pond and the like, rainwater is mainly subjected to percolation and emptying time control (delayed discharge is used for increasing SS retention time) to realize total pollutant amount control, rainwater is not directly discharged outside but discharged outside after being treated to achieve a certain effect, and runoff pollution control is an important content of total amount control, so that the situation also belongs to the category of total amount control, namely 'discharge after treatment'.
The general road sponge city construction is a regulation and storage facility designed by preferentially adopting an ecological drainage mode for rainwater on the road surface and draining the rainwater into the underground space of the road and the surrounding public land if necessary. Before road runoff rainwater enters low-influence development facilities in green lands inside and outside a red line of a road, the runoff rainwater entering the green lands is pretreated by using a sedimentation tank, a preposed pond and the like, so that the damage of the runoff rainwater to the green land environment is prevented; when the green space in the red line is not enough, the road rainwater is introduced into the low-influence development facilities in the green space outside the red line of the road in the city to be consumed, and the low-influence development facilities are connected with the urban rainwater pipe system through the overflow drainage system, so that the smoothness of the upstream and downstream drainage systems is ensured.
When the road is narrow and no green land is available outside the red line, the sponge urban facilities of the road can be built only on only a small green land on the sidewalk, and the green land cannot have a large height difference with the sidewalk in order to ensure the walking safety of people, so that the traditional low-influence development and storage facilities such as rainwater gardens and the like are difficult to implement.
Patent CN207582239U discloses a be applied to road structure of sponge city construction, including pavement, aqueduct and rainwater garden, the pavement is including permeating water concrete layer and guarantor's water layer, the concrete layer that permeates water of pavement is located the top, guarantor's water layer is located permeate water concrete layer's below, the upper end of aqueduct with guarantor's water layer intercommunication, the lower extreme and the pipeline intercommunication in the municipal pipe network of aqueduct, the rainwater garden sets up one side of pavement, the upper surface slope on the concrete layer that permeates water on the pavement sets up, and to rainwater garden side slope, the ground surface in rainwater garden is less than the upper surface of pavement. On the one hand, rainwater on the sidewalk is collected, on the other hand, the rainwater on the sidewalk is drained to the rainwater garden to be utilized, the rainwater utilization rate is improved, and the drainage speed of the sidewalk during raining is improved. However, the structure cannot have the functions of regulating and storing rainwater and purifying rainwater, cannot effectively reduce the urban rainwater discharge peak value, reduces the drainage pressure of the existing drainage pipe network, and is limited for improving the water quality of the river channel.
