A ride-on modular sill flood bank construction according to embodiments of the present invention is described in detail in two specific embodiments with reference to figures 1 to 4. 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 straddle-type composite girder construction for flood protection according to the first embodiment of the present invention includes a bank 100, piers 200, rear piles 300 and girders 400, the bank 100 is disposed at both sides of a river and has an excavated groove 110 at one end near water, the piers 200 are disposed at an outer side of the bank 100 at a distance, the rear piles 300 are disposed at an inner side of the bank 100 at a distance, and the girders 400 are connected to the piers 200 and the rear piles 300, wherein the rear piles 300 are disposed below the excavated groove 110, the piers 200 are divided into pier piles 230, pier bodies 220 and pier caps 210 from bottom to top, and the girders 400 are divided into straight beam portions 410, oblique beam portions 420 and splicing portions 430 from the bank 100 to the river. Specifically, the splices 430 of the girder 400 are connected to the coping 210 above the pier 200, most of the straight beam portion 410 connected to the rear pile foundation 300 is defined in the cutout groove 110, and the upper end surface of the straight beam portion 410 defined in the cutout groove 110 is flush with the upper end surface of the bank 100. It is understood that the straight beam portion 410 may be defined in the excavated groove 110, and in this case, the joint between the straight beam portion 410 and the inclined beam portion 420 is located at the edge of the bank 100, which may increase the construction requirements to some extent. 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. The dug-out groove 110 is a groove dug down a certain depth of the bank 100 to accommodate the straight beam portion 410.

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.

In a further embodiment of the present invention, as shown in fig. 1, the splice 430 of the girder 400 is set to be consolidated with the coping 210, and similarly, the straight beam portion 410 of the girder 400 is also consolidated with the rear pile foundation 300. The pier 200, the girder 400 and the rear pile foundation 300 form a straddle combined rigid frame structure, so that the structure has better integrity, a support does not need to be arranged, and the economical efficiency is good. It should be noted that one way of consolidation is that both are cast together with concrete.

As shown in fig. 1 to 3, in the embodiment of the present invention, the depth of the cutout groove 110 is set to be greater than the height of the straight beam portion 410, and likewise, the width of the cutout groove 110 is set to be greater than the width of the straight beam portion 410. A gap is formed between the cutout groove 110 and the straight beam portion 410, the gap is defined as a waterproof layer 112 and a reserved deformation joint 111 in the direction from the cutout groove 110 to the straight beam portion 410, and the thickness of the waterproof layer 112 is generally set to be greater than the thickness of the reserved deformation joint 111. The reserved deformation joint 111 reserves a space for deformation of the straight beam portion 410, so that influence of extra load generated by deformation on the bank 100 is avoided, and safety of the bank 100 is guaranteed. The waterproof layer 112 is provided to fill with a waterproof material to prevent water in the river from flowing into the gap between the straight beam portion 410 and the excavation groove 110 after rising, and thus to prevent erosion of the bank 100. Preferably, in this embodiment, the waterproof layer 112 is formed by pouring the waterproof concrete 500, and compared with the ordinary concrete, the crack resistance and the impermeability of the waterproof concrete 500 are enhanced, so that the service life is improved while the waterproof function is realized.

Preferably, referring to fig. 3, the straight beam portion 410 has a rectangular cross section defined in the cutout groove 110, and has a simple cross-sectional shape and a high structural rigidity. In contrast, the sloping beam portion 420 can be shaped as desired.

In a further embodiment of the present invention, referring to fig. 1, the height of the end surface of the girder 400 defined in the excavated groove 110 is lower than the height of the end surface of the girder 400 of the pier 200, i.e., the inclined beam portion 420 is inclined upward, and the two sides of the bridge are sloped upward, thereby preventing the water of the river from submerging the two bridges. It is conceivable that both sides of the bridge may be level roads, in which case the height of the end surface of the girder 400 defined in the excavated groove 110 is equal to the height of the end surface of the girder 400 of the pier 200.

In a further embodiment of the present invention, referring to fig. 1 and 2, the end width of the girder 400 defined in the excavated groove 110 is greater than the end width of the girder 400 on the coping 210, that is, the sloped beam portion 420 narrows the road from the bank to the bridge, thereby reasonably allowing the traffic on the bank to flow into the bridge. It is contemplated that the width of the end surface of the girder 400 defined in the excavated groove 110 may be equal to the width of the end surface of the girder 400 of the coping 210, and the width of the road merging into the bridge on the bank is constant.

In some embodiments of the present invention, referring to fig. 2, three rear pile foundations 300 are provided, and the three rear pile foundations 300 are distributed below the excavation grooves 110, so as to better support the main beam 400 and ensure the stability and the firmness of the main beam 400. It can be understood that, the number of the rear pile foundations 300 has a certain relationship with the width of the main beam 400, when the width of the main beam 400 is smaller, the number of the rear pile foundations 300 is larger as the width of the main beam 400 is larger.

Example 2:

a bridge according to a second embodiment of the utility model comprises a straddle-combination sill flood bank construction according to the above-described first embodiment of the utility model.

According to the bridge provided by the embodiment of the utility model, the embankment on two sides of the river channel is constructed to straddle the combined beam platform flood control embankment, so that a series of costs caused by completely breaking and recovering the embankment are reduced, the bridge is smoothly connected with the embankment, the elevation of the embankment is not required to be raised, and the damage to the landscape of the embankment 100 is avoided. Moreover, the girder 400, the coping 210 and the rear pile foundation 300 form a straddle type rigid frame structure, no additional support seat is needed, and better integrity is achieved. The whole construction is convenient, the economy is good, and the long-term maintenance cost of the bridge is effectively reduced.

Referring to fig. 4, in some embodiments of the utility model, the straddling modular sill flood dams are joined by a bridge superstructure 700 on either side of the dam. At the specific joining position, a support 600 is provided on the coping 210, and the bridge superstructure 700 is mounted on the support 600.

Other constructions and operations of bridges according to embodiments of the present invention are known to those of ordinary skill in the art and will not be described in detail herein.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
