If it is described as first, second, it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the sequence of indicated technical features.

[0033] In the description of the present application, unless otherwise explicitly limited, the words such as setting, installing, connecting, etc. should be understood broadly, and the person skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical scheme.

[0034] For buildings at the junction of land and water, it is easy to be affected by thermal expansion and contraction or tides to change in volume, and then cause large deformation. In order to prevent the railing from being bent or broken due to the deformation of the bridge, the railing is generally split type, and the connecting structure is arranged between the adjacent railings to realize connection, although it can meet the needs of deformation, but when the water level is too high due to unexpected circumstances, water is easy to flow over the bridge from the connecting part and affect the bridge structure. If the traditional water stop structure is used, its deformation ability is insufficient, and it is also difficult to use in the use scene with large deformation amplitude.

[0035] Therefore, the first aspect of the present application provides a water stopping device for installation between bridge railings on the banks of rivers, lakes and seas, which can connect the railings and prevent water from overflowing the road surface through the gaps between the railings. The water stopping structure 400 mainly comprises a first baffle 410 and a second baffle 420 that are helically engaged with each other, and are connected to adjacent first and second railings 100 and 200, respectively. The first and second baffles 410 and 420 both extend to the road surface, thereby preventing water from overflowing the road surface. At the same time, since the first and second baffles 410 and 420 are both elastic members, when the road surface deforms, the engagement portions of the first and second baffles 410 and 420 can also deform correspondingly, thereby continuously achieving the water stopping effect, and the first and second baffles 410 and 420 are not prone to loosening due to excessive deformation. Compared with the conventional water stopping structure, the present application has more significant progress.

[0036] The second aspect of the present application provides a construction method based on the above water stopping device, which introduces the construction process of the present water stopping device.

[0037] Referring to Figure 1 The water stopping device in the first embodiment of the present application comprises a first railing 100, a second railing 200 and a water stopping structure 400. The first and second railings 100 and 200 are adjacent railings, and the water stopping structure 400 is located between and connected to the two railings, thereby filling the gap between the first and second railings 100 and 200. The first and second railings 100 and 200 are both closed structures without openings, thereby preventing water from overflowing the road surface through the openings of the railings. Figure 2 A reference axis 300 extending in a first direction z is arranged between the first and second railings 100 and 200.

[0038] The water stopping structure 400 is the core structure of the present water stopping device, and comprises a first baffle 410 and a second baffle 420. The first and second baffles 410 and 420 are both elastic members, which are made of composite materials or steel and have elasticity or ductility. The first and second baffles 410 and 420 both extend to the road surface in the first direction z, thereby preventing water from seeping into the gap between the baffles and the road surface. Rubber strips can be installed on the side of the first and second baffles 410 and 420 that contacts the road surface, thereby improving the water stopping performance. The first and second baffles 410 and 420 both comprise an integral connection portion and an engagement portion. The connection portion of the first baffle 410 is fixed to the first railing 100, and the connection portion of the second baffle 420 is fixed to the second railing 200. The engagement portions of the first and second baffles 410 and 420 are helically bent in the same clockwise direction around the reference axis 300 and engaged with each other, thereby achieving the fixation between the first and second baffles 410 and 420.

[0039] When the bridge deforms greatly, the first rail 100 and the second rail 200 will displace accordingly, which may cause the distance between the two to increase, and the first baffle 410 and the second baffle 420 will also move away from each other. However, due to the helical engagement structure of the two baffles, the first baffle 410 and the second baffle 420 will partially disengage but still engage with each other, so as not to be separated. When the bridge returns, the first rail 100 and the second rail 200 will move closer to each other, and the first baffle 410 and the second baffle 420 will re-engage under the action of their own elastic force, without affecting the normal use of the water stop structure 400.

[0040] Further, in some embodiments, the connecting portion of the first baffle 410 is connected to the first rail 100 by bolts, and the connecting portion of the second baffle 420 is connected to the second rail 200 by bolts, which realizes mutual fixation by bolt connection, facilitating installation and also facilitating disassembly for maintenance in the later period. In other embodiments, the first baffle 410 and the second baffle 420 are both steel plates, the connecting portion of the first baffle 410 is welded with the internal steel bars of the first rail 100, and the connecting portion of the second baffle 420 is welded with the internal steel bars of the second rail 200, so as to have higher connection strength and not easy to be loosened.

[0041] Further, the number of helical turns of the engagement portion of the first baffle 410 and the engagement portion of the second baffle 420 is greater than 1 turn, so as to ensure that the two are tightly engaged and not to be loosened when the road surface deforms too much.

[0042] Further, the water stop structure 400 further comprises a filling layer 430, which is filled between the engagement portion of the first baffle 410 and the engagement portion of the second baffle 420, for buffering the impact between the first baffle 410 and the second baffle 420, and also reducing the wear that may occur when the two are engaged. The filling layer 430 can also absorb water, absorbing the residual water between the first baffle 410 and the second baffle 420 and reducing water accumulation.

[0043] Further, the water stop structure 400 further comprises an end plugging structure 440 extending along the first direction z, the two sides of the end plugging structure 440 being connected to the first baffle 410 and the second baffle 420 respectively, and abutting against the filling layer 430, to prevent the filling layer 430 from coming out.

[0044] For the connection mode of the first baffle 410 and the second baffle 420, the present application proposes three possible embodiments:

[0045] With reference to Figure 3 , the first baffle 410 and the second baffle 420 are separated from each other and filled with the filling layer 430, which has simple production process and installation mode, low cost, and is suitable for most use environments.

[0046] Referring to Figure 4 , the end of the first baffle plate 410 and the end of the second baffle plate 420 are connected as a whole, which can be welded or bolted, so that the connection of the first baffle plate 410 and the second baffle plate 420 is more stable, has a larger deformation range, and is suitable for large deformation use scenarios.

[0047] Referring to Figure 5 , the water stop structure 400 further comprises a connecting piece 450, the two ends of the connecting piece 450 are connected to the end of the first baffle plate 410 and the end of the second baffle plate 420 respectively, so as to realize the connection of the first baffle plate 410 and the second baffle plate 420, which has higher connection strength and facilitates the installation and disassembly of the first baffle plate 410 and the second baffle plate 420.

[0048] The second aspect embodiment of the present application provides a construction method based on the above-mentioned water stop device, comprising the following steps:

Clamping the first baffle plate 410 or the second baffle plate 420 in the mechanical equipment, the mechanical equipment in the present application refers to the equipment that can exert external force on the baffle plate and bend, and the occlusion part of the first baffle plate 410 or the second baffle plate 420 is generated by the rotation of the mechanical equipment;
