Description

Technical Field

[0001] The utility model relates to the technical field of bridge structure expansion joint processing, and more particularly to an expansion joint water receiving box structure. Background Art

[0002] The expansion joints of bridge structures in the prior art are often treated in the following ways:

[0003] Set up U-shaped, V-shaped or W-shaped metal plates, and fill the metal plates with elastic filling materials such as asphalt hemp to prevent water from leaking downwards from the bridge surface.

[0004] The sliding steel plate design is fully fitted to the surface, isolating the bridge deck water from seeping downwards;

[0005] Flat steel plates are laid on the structural expansion joints, and the joints are filled with elastic fillers such as asphalt and hemp. Simple slits are cut in the pavement layer at the ends of the steel plates to prevent water from seeping downwards from the bridge deck.

[0006] For the steel expansion joints commonly used in vehicle bridges, waterstops are installed to prevent water from seeping downward from the bridge deck.

[0007] When the above treatment method is adopted, during the operation period of the bridge, water seepage and leakage are often caused by missing fillers, rust or damage of metal plates, incomplete sealing between sliding steel plates, and damage of waterstops. Utility Model Content

[0008] The technical problem to be solved by the utility model is to provide a water box structure for expansion joints.

[0009] A water receiving box structure for an expansion joint includes a water receiving box 1 arranged at the bottom of the expansion joint of a bridge structure along the transverse direction of the bridge, a water receiving box 2 connected to the water receiving box 1 at least at one end and arranged along the longitudinal direction of the bridge, and a drainage pipe connected to the water receiving box 2 at one end away from the water receiving box and located at the bottom of the water receiving box 2.

[0010] In some possible implementations, the first water receiving box includes a water collecting trough that is connected to the second water receiving box and is arranged along the transverse bridge direction.

[0011] In some possible implementations, the water collection tank includes a bottom plate, side plates arranged on both sides of the bottom plate and connected to the bottom plate, and a fixing plate arranged parallel to the bottom plate and connected to the bottom of the bridge;

[0012] The fixed plate is located outside the water collecting trough; the distance between the two sets of side plates close to one end of the bridge is greater than the width of the structural expansion joint.

[0013] In some possible implementations, a water inlet communicating with the second water receiving box is provided on the side panel.

[0014] In some possible implementation manners, the water receiving box two comprises a water conveying groove connected with the water outlet and having the same structure as the water collecting groove, and an end plate two arranged at an end of the water conveying groove away from the water collecting groove.

[0015] In some possible implementation manners, the fixing plate is connected with the bottom of the bridge through steel nails.

[0016] In some possible implementation manners, sealing glue is arranged between the bottom of the bridge and the fixing plate.

[0017] In some possible implementation manners, a drainage hole in communication with the drain pipe is arranged on the bottom plate of the water receiving box two away from the water receiving box one.

[0018] Compared with the prior art, the utility model has the beneficial effects of:

[0019] The utility model can effectively realize the treatment of the seepage and leakage of the expansion joint of the bridge structure, and can effectively realize the maintenance of the bridge during the operation period without interrupting the traffic.

[0020] The utility model can be simultaneously implemented when the seepage and leakage disease is treated, the seepage and leakage flow direction is controlled, and the operation safety of the bridge is ensured.

[0021] The utility model can also be applicable to installation in the construction stage, and can prevent the large-area seepage and leakage phenomenon, and can affect the aesthetic property and the durability. BRIEF DESCRIPTION OF DRAWINGS

For example, they can refer to fixed connections, removable connections, or integration; they can refer to direct connections or indirect connections through an intermediary; they can refer to internal communication between two components or interactions between two components. The terms "first," "second," and similar terms mentioned in this application do not denote any order, quantity, or importance; they are simply used to distinguish between different components. Similarly, terms such as "a" or "an" do not indicate a quantitative limitation; rather, they indicate the presence of at least one. In the implementation of this application, "and / or" describes an association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. In the description of the embodiments of this application, unless otherwise specified, "plurality" means two or more. For example, "plurality" refers to two or more positioning posts.
