Abstract
Description
Technical Field
[0001] This invention belongs to the field of flood control, drainage and disaster reduction, and specifically designs an underground flood diversion channel system, which is mainly used to improve the design standards of flood control and drainage in urban areas. Background Technology
[0002] Currently, many cities in China have existing river networks that do not meet flood control standards. In order to improve the flood control capacity of urban rivers, it is necessary to widen some sections of existing rivers. At present, the general approach is still "widening the river + dredging". However, land around the rivers in the central urban area is scarce, and due to the influence of buildings on both banks, many existing rivers do not have the conditions for widening. In order to ensure the flood control safety of the rivers, flood diversion projects are often built at suitable locations in the rivers. However, the frequency of use of general flood diversion channels is low, usually only once or twice a year, or even once every ten years or more. The existing design concept of "flood diversion channel" has the disadvantages of "single function" and "large investment in tunnel construction".
[0003] The purpose of this invention is to provide an intensive underground space for flood diversion and storage in urban rivers, addressing the problems of current urban river flood control standards not being met, flood diversion channels having limited functions, and high investment costs. Summary of the Invention
[0004] The present invention aims to overcome the problems of single function and low usage frequency of existing flood diversion channels, and provides an intensive underground space for flood diversion and storage of urban rivers. It combines flood diversion and parking functions, increases usage frequency, enhances the return on investment of flood diversion projects, and effectively alleviates the current parking difficulties in cities.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] The present invention relates to an intensive underground space for flood diversion and storage in urban river channels.
[0007] The present invention provides an intensive underground space for flood diversion and storage in urban rivers, comprising a flood diversion channel and a multi-functional box culvert. The flood diversion channel is arranged beside the urban river, and at least one multi-functional box culvert is arranged on the flood diversion channel. Passenger and vehicle passages are provided at both ends of the multi-functional box culvert, and parking spaces are provided on the bottom surface of the interior of the multi-functional box culvert.
[0008] Preferably, the flood diversion channel inlet connects to the upstream of the river channel, and the flood diversion channel outlet connects to the middle and downstream of the river channel. The length of the flood diversion channel is less than the length of the river channel between the inlet and outlet of the flood diversion channel.
[0009] Preferably, the elevation of the upper surface of the bottom slab at the entrance of the flood diversion channel is higher than the elevation of the upper surface of the bottom slab at the exit of the flood diversion channel, thus forming a longitudinal slope on the bottom surface of the flood diversion channel.
[0010] Preferably, the elevation of the upper surface of the bottom plate at the entrance of the flood diversion channel is 30cm higher than the normal water level of the river, and the elevation of the upper surface of the bottom plate at the outlet of the flood diversion channel is 10cm higher than the normal water level of the river.
[0011] Preferably, the flood diversion channel is equipped with control gates at both ends. The control gates are closed during normal operation, and the multi-functional box culvert functions as a parking lot. When flood diversion is required, the control gates are opened, and the flood diversion channel and the multi-functional box culvert work together to perform the flood diversion function.
[0012] Preferably, the bottom plate surface of the flood diversion channel and the multi-functional box culvert is provided with grooves, through which seepage water when the flood is not diverted, residual silt after the flood is diverted, and cleaning wastewater from the flood diversion channel are discharged.
[0013] Preferably, a steel grating cover is provided on the groove for vehicle passage.
[0014] As a preferred option, the elevation of the bottom surface of the parking space inside the multi-functional box culvert is 20cm higher than the elevation of the bottom surface of the flood diversion channel.
[0015] Preferably, the multi-functional box culvert is provided with a first passage and a second passage at both ends. The first passage is equipped with an entrance parking elevator and an exit parking elevator, and the second passage is equipped with a fire escape staircase and a passenger elevator.
[0016] Preferably, the multifunctional box culvert is constructed of impermeable concrete.
[0017] Therefore, the present invention has the following beneficial effects:
[0018] When implementing this plan, appropriate underground flood diversion channel inlets and outlets will be selected based on the terrain conditions. The underground space of urban public land such as municipal roads and green spaces will be used to arrange the flood diversion channels, eliminating the problem of land acquisition difficulties and making implementation easy. The flood diversion channels will preferentially adopt cast-in-place concrete structures, whose roughness is much lower than that of the original river channel, resulting in better flood diversion effect.
[0019] The flood diversion channel is equipped with multi-functional box culverts. Multiple box culverts that meet parking functions can be set up according to actual needs and construction conditions, providing different numbers of parking spaces to meet different social needs and making it more humane.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0027] like Figure 1 , Figure 2 As shown, this invention discloses an intensive underground space for flood diversion and storage in urban rivers, comprising a flood diversion channel 2 and a multi-functional box culvert 3. At least one multi-functional box culvert 3 is arranged on the flood diversion channel 2. The interior bottom surface of the multi-functional box culvert 3 is provided with a vehicle passageway 8 and parking spaces located on both sides of the vehicle passageway. The vehicle passageway 8 extends longitudinally along the multi-functional box culvert 3. In specific implementation, the multi-functional flood diversion box culverts 3 are positioned and numbered appropriately based on the surrounding urban functional needs and actual land use conditions.
[0028] The inlet of flood diversion channel 2 connects to the upstream of the river channel, and the outlet of flood diversion channel 2 connects to the middle and downstream of river channel 1. The length of flood diversion channel 2 is less than the length of river channel 1 between the inlet and outlet of flood diversion channel 2.
[0029] When selecting the specific route for flood diversion channel 2, it should be located in a bend in the river channel as much as possible. The design of flood diversion channel 2 should be as straight as possible so that the length of flood diversion channel 2 is less than the length of the river channel between the inlet and outlet of the flood diversion channel, thus achieving higher flood diversion efficiency.
[0030] The elevation of the upper surface of the bottom plate of the flood diversion channel inlet 13 is higher than the elevation of the upper surface of the bottom plate of the flood diversion channel outlet 14, and the bottom surface of the flood diversion channel 2 forms a longitudinal slope.
[0031] The elevation of the upper surface of the bottom plate of the flood diversion channel inlet 13 is 30cm higher than the normal water level of the river channel, and the elevation of the upper surface of the bottom plate of the flood diversion channel outlet 14 is 10cm higher than the normal water level of the river channel.
[0032] The flood diversion channel 2 is equipped with control gates 12 at both ends. The control gates 12 are closed during normal operation, and the multi-functional box culvert 3 functions as a parking lot. When flood diversion is needed, the control gates 12 are opened, and the flood diversion channel 2 and the multi-functional box culvert 3 work together to perform flood diversion. The elevation of the bottom surface of the parking space 17 is 20cm higher than the elevation of the bottom surface of the flood diversion channel 2.
[0033] like Figure 3 As shown, the bottom plate surface of the multifunctional box culvert 3 is provided with grooves 18 for seepage when there is no flood diversion, passage of residual mud and sand after flood diversion, and passage of wastewater and waste residue when cleaning wastewater in the flood diversion channel.
[0034] The groove 18 is provided with a steel grating cover 19 to facilitate vehicle passage.
[0035] The bottom plate of the main body of the flood diversion channel 2 is provided with a longitudinal slope.
[0036] The flood diversion channel 2 and the multi-functional box culvert 3 are preferably cast-in-place concrete structures, with a roughness much lower than that of the original river channel.
[0037] Both the flood diversion channel 2 and the multi-functional box culvert 3 are cast-in-place impermeable concrete structures.
[0038] like Figure 4 , Figure 5 As shown, a multi-functional box culvert 3 with parking function is installed along a section of the flood diversion channel. This box culvert 3 can be used for parking normally, but will be closed in advance during the flood season to serve as part of the overall flood diversion channel for flood discharge. The box culvert's location should be integrated with public green spaces or municipal roads 20. In this embodiment, integration with a municipal road is taken as an example. The specific above-ground and underground plan layouts of the box culvert are as follows: Figure 3 , 4 As shown.
[0039] The longitudinal direction of the multi-functional box culvert 3 is generally consistent with the transverse direction of the ground road, and its longitudinal length should be greater than or equal to the transverse width of the urban road. A first passage 4 and a second passage 5 are respectively set at both ends of the multi-functional box culvert 3. The first passage 4 is equipped with an entrance parking elevator 6 and an exit parking elevator 7, and the second passage 5 is equipped with a fire escape staircase 9 and a passenger elevator 10. A vehicle passage 8 is located between the first passage 4 and the second passage 5. Parking spaces are arranged on both sides of the vehicle passage 8.
[0040] The lateral width of the multi-functional box culvert 3 is 16m. The longitudinal length of a single multi-functional box culvert 3 is 40m to 60m. The multi-functional box culvert 3 is used as a garage, with a single row of parking spaces, each space measuring 5.3m × 2.4m.
[0041] The parking system of the multi-functional box culvert 3 also includes an equipment room 11, which is equipped with an electromechanical control system and an exhaust shaft. The electromechanical control system is electrically connected to the parking system and the elevator, respectively.
[0042] When implementing this plan, appropriate underground flood diversion channel inlets and outlets will be selected based on the terrain conditions. The underground space of urban public land such as municipal roads and green spaces will be used to arrange the flood diversion channels, eliminating the problem of land acquisition difficulties and making implementation easy. The flood diversion channels will preferentially adopt cast-in-place concrete structures, whose roughness is much lower than that of the original river channel, resulting in better flood diversion effect.
[0043] The flood diversion channel is equipped with multi-functional box culverts. Multiple box culverts that meet parking functions can be set up according to actual needs and construction conditions, providing different numbers of parking spaces to meet different social needs and making it more humane.
