Description

Technical Field

[0001] This utility model relates to the field of water-cutting joint equipment, specifically to a novel steel structure water-cutting joint for tunnel pavement. Background Technology

[0002] Highway tunnel entrances (especially those with downhill entrances or uphill exits) typically require transverse intercepting ditches to intercept rainwater from the road surface. Traditional intercepting ditch designs generally use open drainage ditches covered with slabs (steel or concrete). Due to the lightweight nature of the components, unreliable connections, and poor durability, these ditches often suffer from the following problems: unevenness is difficult to guarantee, leading to loosening or deformation under repeated vehicle traffic, causing vehicle bouncing and affecting driving comfort; damaged or deformed ditch covers can cause tire punctures, posing a safety hazard; components are subjected to constant vehicle impact loads, resulting in a short service life and frequent replacements, significantly increasing operating costs and posing substantial safety risks due to frequent maintenance; and construction quality is difficult to guarantee, leading to problems such as poor drainage and insufficient strength. Utility Model Content

[0003] The main purpose of this utility model is to provide a new type of steel structure water interception joint for tunnel pavement, which aims to solve the problems of poor load-bearing durability and short service life of traditional water interception ditches with existing drainage ditch covers.

[0004] To achieve the above objectives, this utility model proposes a novel steel structure water-cutting joint for tunnel pavement, comprising a support box, a damping plate, and a crossbeam; both ends of the crossbeam are provided with support boxes and damping plates; the damping plate is connected to the crossbeam, and the damping block is disposed between the damping plate and the end plate of the support box; the support box includes a box body, a sliding support, and a damping block; the box body is connected to the crossbeam through the sliding support, and the damping block is disposed between the damping plate and the crossbeam.

[0005] Preferably, the sliding support is connected to the crossbeam via a stainless steel sliding plate.

[0006] Preferably, the system further includes a waterproof strip, side beam steel, and middle beam steel. The side beam steel is connected to the support box, the middle beam steel is connected to the middle of the crossbeam, one end of the waterproof strip is connected to the middle beam steel, and the other end of the waterproof strip is connected to the side beam steel.

[0007] Preferably, it further includes an anchoring component, which is connected to the side beam steel and is used to connect the side beam steel and the concrete structure.

[0008] Preferably, at least one central beam is provided, and all central beams are connected to the crossbeams, with adjacent central beams connected by the waterproof strip.

[0009] Preferably, multiple sets of support boxes and crossbeams are provided, with each support box connected to the side beam steel and each crossbeam connected to the middle beam steel.

[0010] Preferably, at least two sets of anchoring components are provided, and each anchoring component is connected to the side beam steel.

[0011] Preferably, the width of the end plate is greater than the width of the support box.

[0012] In the technical solution of this utility model, the support box assembly structure and the crossbeam assembly adopt a design of sliding support and damping plate plus high-damping damping block. A sliding spring is installed in the support box to connect with the crossbeam, ensuring that the middle beam steel can slide freely. The damping plate is welded to the end of the crossbeam to increase the force contact area with the high-damping damping block, reduce the wear of the high-damping damping block caused by direct contact of the crossbeam, release the impact of vehicle impact load on the support box and anchor concrete, and enhance durability and extend service life.
