A rigid frame modular sill flood bank construction according to embodiments of the present invention is described in detail in two specific embodiments with reference to fig. 1 to 2. It is to be understood that the following description is illustrative only and is not intended as a specific limitation on the utility model.
Example 1:
as shown in fig. 1, the rigid-frame composite abutment dyke structure according to the first embodiment of the present invention includes a bank 100, piers 200, abutments 300 and girders 400, the bank 100 being distributed on both sides of a river, the piers 200 being disposed outside the bank 100, and the abutments 300 being disposed at the edges of the bank 100. Wherein, pier cap 201 is provided with above pier body 202 of pier 200, and the platform 302 top of abutment 300 is provided with top cap roof beam 301, and specifically, top cap roof beam 301 sets up to be connected with embankment 100, and the up end of top cap roof beam 301 and the up end of embankment 100 parallel and level, and pier cap 201 and top cap roof beam 301 are connected together to girder 400. The bridge can be smoothly connected with the embankment 100, the elevation of the embankment 100 is not raised, and the landscape of the embankment 100 is prevented from being damaged. It will be understood that the bank 100 may be an existing bank 100, a flood bank retrofitted onto an existing bank 100, or a bank 100 constructed with a flood bank.
It should be noted that "level" is not absolutely perfectly horizontal with the upper end face of the bank, since the bank itself may also present a certain level of undulated road. The term "level" is used to mean that a person does not feel a significant rise or fall on the bank.
As shown in fig. 1, in the embodiment of the present invention, a bridge pier 200 is composed of a bridge pier foundation 203, a pier body 202 and a pier cap 201, and a bridge abutment 300 is composed of a bridge abutment pile foundation 303, a pier body 302 and a coping beam 301, wherein the pier body 202 is connected to the bridge pier foundation 203, and the pier body 302 is connected to the bridge abutment pile foundation 303. Specifically, in this embodiment, the abutment body 302 and the abutment pile foundation 303 are configured to be connected through the bearing platform 305 and the back wall 304, specifically, the bearing platform 305 is connected to the abutment pile foundation 303 and the abutment body 302, and the back wall 304 is connected to the bearing platform 305 and the abutment body 302. Further, in this embodiment, the back wall 304 is also connected to the roof rail 301. Since the abutment 300 is different from the bridge pier 200, the abutment 300 plays a role of connecting the upper portion of the bridge with the bank 100, in addition to transmitting the load on the bridge to the abutment pile 303. The arrangement of the bearing platform 305 makes the connection between the abutment pile 303 and the platform body 302 more firm, and the arrangement of the back wall 304 makes the connection of the bearing platform 305, the platform body 302 and the coping 301 more firm. The combination of the two functions enables the abutment 300 to better bear the load on the main beam 400 and the additional load generated by engagement with the bank 100.
As shown in fig. 1, in the embodiment of the present invention, the back wall 304 is disposed at a side close to the bank 100, and the horizontal sectional area of the back wall 304 is gradually increased in a vertically downward direction. Generally, the body 302 is cylindrical, so that river water can wash the bank due to flood tide and earth rotation, and when the back wall 304 is disposed near the bank 100, the energy of the water flow for washing the back wall 304 is partially buffered by the cylindrical body 302, so that the back wall 304 is more durable. It will be appreciated that the provision of a gradually increasing horizontal cross section of the back wall 304 in a vertically downward direction better withstands pressure where the water pressure is greater at deeper water levels. Due to the reasonable arrangement of the position and the shape of the back wall 304, the abutment 300 can better play the roles of resisting the filling pressure behind the abutment, stabilizing the bridge head roadbed and connecting the bridge head circuit and the bridge upper circuit reliably and stably.
In the embodiment of the utility model, referring to fig. 1, the girder 400 includes a first splicing portion 401, a trunk 402 and a second splicing portion 403, the first splicing portion 401 is fixedly connected to the roof girder 301, the second splicing portion 403 is fixedly connected to the coping 201, and the first splicing portion 401 and the second splicing portion 403 are connected by the trunk 402. Two sides of the girder 400 are respectively fixedly connected with the coping beam 301 above the abutment 300 and the coping 201 above the pier 200, so that a rigid frame structure is formed among the girder 400, the abutment 300 and the pier 200. The first splicing part 401 of the girder 400 is fixedly connected with the top cover beam 301, and no gap exists between the bottom of the girder 400 and the bank after the girder is fixedly connected, so that flood cannot enter the bank, water blocking treatment is not needed, the construction is simple, and maintenance is not needed in the later period. The second splicing part 403 of the girder 400 is fixedly connected with the pier cap 201, a supporting support does not need to be arranged, construction is convenient, economical efficiency is good, and long-term maintenance cost of the bridge is reduced. It should be noted that one way of consolidation is that both are cast together with concrete.
In a further embodiment of the utility model, referring to fig. 1, the width of the first splice 401 is equal to the width of the roof rail 301, both of which are better consolidated and the consolidated whole is more aesthetically pleasing.
In a further embodiment of the present invention, referring to fig. 1, the second splicing portion 403 is hook-shaped, and a lower end surface of a hook head of the second splicing portion 403 is fixedly connected to an upper end surface of the pier cap 201, wherein the lower end surface of the hook head is smaller than the upper end surface of the pier cap 201, so that a utilization space is left on the upper end surface of the pier cap 201, which is convenient for one end of the main body of the bridge to be supported thereon, and is better connected to the second splicing portion 403 of the main beam 400.
Example 2:
as shown in fig. 2, a bridge according to a second embodiment of the present invention includes the rigid frame composite sill flood bank structure of the first embodiment of the present invention.
