[0006] As a further improvement of the present invention, powder spray piles are provided at the bottom of the gate bottom plate.

[0007] This utility model combines multiple functions in one: the gates are closed to store water during the non-flood season, raising the river water level to form a hydrophilic landscape, improving the urban water environment and the city's image; the gates are opened to release water during the flood season without affecting the flow of urban rivers; vehicles and pedestrians on both sides of the river can pass during daily operations, playing the role of connecting traffic.

[0008] Compared with the prior art, the utility model has the following advantages:

[0009] 1. The utility model adopts the integrated design of bridge and gate, which avoids the aesthetically unpleasing frame structure and bulky valve form of traditional sluice engineering, and is more in line with the landscape requirements of the city.

[0010] 2. The utility model integrates the construction of bridge and gate, so that the gate bridge is no longer the only purpose of crossing the water system. The comprehensive functional structure effectively saves the bridge space resources across the river.

[0011] 3. The utility model reduces the construction of the sluice working bridge and the sluice chamber by adopting the idea of ​​building the bridge and the sluice together, effectively avoids the repeated investment caused by the separate construction of the bridge and the sluice, and saves social resources.

[0020] The present invention will be described in detail below with reference to the accompanying drawings.

[0021] Example 1

[0022] like Figure 1-3 As shown, a gate-bridge combination structure for urban river management includes a bridge body 2, a lower horizontal flat plate gate is provided at the bridge hole 21, a gate base plate 3 is provided below the bridge hole 21, the lower horizontal flat plate gate includes a gate plate 11, a gate hoist 12 and a gate support 13, the gate support 13 is installed on the gate base plate 3, the bottom of the gate plate 11 is hinged to the gate support 13, the gate plate 11 is connected to the inner wall of the bridge hole 21 through the gate hoist 12, and the two ends of the gate hoist 12 are rotatably connected to the gate plate 11 and the inner wall of the bridge hole 21 respectively.

[0023] A gate groove 31 for accommodating the gate plate 11 is formed on the upper surface of the gate bottom plate 3 .

[0024] A powder spray pile 32 is provided at the bottom of the gate bottom plate 3 .

[0025] The gate opening and closing machine 12 adopts an electro-hydraulic integrated gate opening and closing machine, which is a gate opening and closing machine device integrating mechanical, electrical and hydraulic functions. It consists of a hydraulic cylinder, an oil pump, an electric motor, an oil storage tank, an oil filter, an integrated valve group, etc. When in use, by turning on the power supply, the piston rod can be made to move back and forth, thereby realizing the opening and closing state of the gate.

[0026] The gate support 13 is installed on the gate base plate 3 through embedded parts 14.

[0027] The hoist 12 is installed on the inner wall of the bridge hole 21 through the hoist cap 22. The hoist 12 is symmetrically installed on both sides of the bridge hole 21, and works simultaneously and synchronously, which effectively ensures the stability during the opening and closing process.

[0028] Bridge body 2 is not only a traffic bridge across the river, but also serves as a lock chamber. It can also be used as a working bridge for installing opening and closing equipment and for maintenance.

[0029] In this embodiment, the bridge 2 is a single-span arch bridge. The arch ribs are reinforced concrete slabs with a circular arch axis that is elevated above the reservoir level. The arch sidewalls are filled with crushed stone concrete, and the top surface is paved with a 20cm thick layer of cast-in-place C20 concrete. A rectangular corbel is installed inside the arch ribs, serving as the hoist cap 22. The steel bars of the hoist cap 22 extend into the arch ribs and are tied to the other steel bars to form a mesh.

[0030] The lower horizontal flat gate is a control device that closes and opens the waterway, intercepting the water flow, controlling the water level, regulating the flow rate, and discharging sediment and floating debris. Its height is determined by the regulated water level. The width of the gate plate 11 is not less than the clear width of the arch seat 23.

[0031] The gate base plate 3 is interrupted by a 2cm expansion joint, which is filled with asphalt hemp. The gate base plate 3 is a rectangular reinforced concrete structure with a recessed gate slot 31. When the gate plate 11 is opened, it can be completely embedded in it to avoid blocking flood discharge. To prevent water from hollowing out the foundation beneath the gate base plate 3 during flood discharge, powder injection piles 32 are installed underneath the gate base plate 3 to reinforce the foundation and improve its bearing capacity and stability.

[0032] When the sluice gate is storing water, it presents a landscape of small bridges and flowing water; when the sluice gate is releasing water, it presents the scene of Magpie Bridge Waterfall.

[0033] Example 2

[0034] The difference between this embodiment and embodiment 1 is that the bridge body 2 is a double-hole rectangular reinforced concrete frame bridge, and a set of horizontal flat gates is set at each bridge hole 21, such as Figure 4-6shown.

[0035] Variable-height arm-type concrete retaining walls 4, cast with C30 concrete, are installed on both the upstream and downstream sides of the bridge head. Gabion stone floodplains 5, hydraulic energy dissipation and anti-scour facilities, are installed on both the upstream and downstream sides of the bridge body 2. These serve to eliminate excess energy in the water flow, adjust the flow velocity distribution, and evenly diffuse the water outflow, making it similar to the flow state of a natural river channel, thereby protecting the riverbed from scour. A 10cm thick C15 concrete cushion layer is placed on the bottom surface of the gabion stone floodplain 5. To improve its stability, a clay layer of more than 12cm is arranged under the cushion layer to reduce the seepage pressure at the bottom of the gate and prevent pipe bursts. The foundations of the bridge body 2 and the gabion stone floodplain 5 are both treated with powder injection piles, arranged in a plum blossom shape on the plane, and the pile bodies are made of ordinary Portland cement.

[0036] A functional building 6 is located on the riverbank for the sluice gate management personnel to live and work, and also serves as a place to store supplies and equipment during flood season. Functional building 6 is connected to the road through a work path 7, making it easy for management personnel to enter and exit.

[0037] In this embodiment, the river channel can be desilted by utilizing the impact force of the water flow through a single-hole flood discharge method, thereby effectively solving the problem of siltation in urban rivers.

[0038] While realizing the traffic function, the utility model can also play the role of flood prevention, flow control and water level regulation. At the same time, it avoids the aesthetically pleasing frame structure and bulky valve form of traditional sluice projects, better meets the landscape requirements of the city, and has strong practicality.
