Description

Technical Field

[0001] The utility model relates to the technical field of highway bridges and culverts, and relates to an anti-seepage connection structure for a corrugated steel structure channel. Background Art

[0002] A corrugated steel structure channel refers to a channel built below the road surface on the road bridge foundation, assembled from corrugated steel plates, used to drain flood water across natural valleys and depressions, or to cross large and small roads as an elevated traffic passage for people, livestock and vehicles, or as a canal for farmland irrigation.

[0003] Corrugated steel structures include two cross-sectional forms: open section and closed section, and the shapes generally include arch, circular and box-shaped.

[0004] The existing corrugated steel structure channel is assembled from multiple plates, which are connected by high-strength bolts. The connection is either a direct bolt connection between the plates or a flange connection at the end of the plates. The similarities are that water-expandable rubber strips are arranged on the front of the plate connection, and the side of the plate connection is fully coated with structural sealant as a leakage prevention design.

[0005] Due to construction factors, the water in the above structure gradually seeps into the culvert through the bolt holes, annular and axial plate gaps, making it fail to meet the anti-seepage requirements of the corrugated steel structure channel.

[0006] Therefore, it is necessary to develop a new type of anti-seepage connection that can not only achieve the water separation and anti-seepage functions, but also enable quick connection. Utility Model Content

[0007] The utility model provides a corrugated steel structure channel anti-seepage connection to solve the problem of water seeping into a pipe.

[0008] In order to overcome the problems existing in the prior art, the technical solution adopted by the utility model is: a corrugated steel structure channel anti-seepage connection structure, including a plurality of annular corrugated tubes, each of which includes a plurality of arc-shaped outer corrugated plates and inner corrugated plates, outer connecting plates are vertically arranged at both ends of each outer corrugated plate, inner connecting plates are vertically arranged at both ends of each inner corrugated plate, the inner connecting plates and the outer connecting plates connect the staggered outer corrugated plates and the inner corrugated plates into one, and two adjacent annular corrugated tubes are connected by an axial connecting piece.

[0009] Furthermore, the inner connecting plate and the outer connecting plate are respectively corrugated flat plates, and are connected by a plurality of high-strength bolts.

[0010] Furthermore, a waterproof sealing strip is provided between the outer corrugated plate sheet and the inner corrugated plate sheet.

[0011] Furthermore, the axial connecting member is a plurality of arc-shaped components with T-shaped cross-sections.

[0012] Furthermore, each arc-shaped component is connected to two adjacent annular bellows by means of high-strength bolts.

[0013] Furthermore, a second waterproof sealing strip is provided between each arc-shaped component and two adjacent annular corrugated tubes.

[0014] Furthermore, two sides of the arc-shaped top plate of the arc-shaped component are pressed onto two adjacent annular bellows.

[0015] Furthermore, sealants are provided at the outer connecting parts of the outer corrugated plate sheets and the inner corrugated plate sheets and at the outer connecting parts of the inner connecting plates and the outer connecting plates, respectively.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] 1) The utility model adopts an annular anti-seepage connection, which adopts an inner connection and outer cover overlap design, fundamentally cutting off the water seepage of the bolt holes, and the plate connection is simple, and the assembly speed is faster;

[0018] 2) The utility model adopts a shunting cover design for the axial anti-seepage connection, which makes up for the shortcomings of the axial flange anti-seepage design and improves the anti-seepage function of the corrugated steel structure channel;

[0019] 3) The utility model has a simple structural design and improves the durability and traffic comfort of the corrugated steel structure channel. BRIEF DESCRIPTION OF THE DRAWINGS
