Description

TECHNICAL FIELD

[0001] The utility model relates to a corrugated pipe connecting structure, in particular to a steel corrugated pipe reinforced connecting structure. BACKGROUND

[0002] In the fields of buildings, tunnels, culverts, water transportation and irrigation, corrugated pipes are widely used as supporting structures. To achieve stable support and fixation and facilitate construction, such corrugated pipes are usually designed in sections and connected by welding or bolting. However, in actual construction, the existing general technology involves setting long holes on the left and right sides of the corrugated plates, stacking them and locking them horizontally with bolts to achieve horizontal connection and fixation.

[0003] However, the above structure has the following disadvantages in actual use: 1. The horizontal bolts connecting multiple corrugated plates increase the vertical shear force of the horizontal bolts, which poses a high risk of cutting and may even cause the support point to collapse in severe cases; 2. The left and right sides of the corrugated plates are locked by through bolts, which has poor sealing performance and may cause internal and external space to be penetrated, making it difficult to achieve maximum sealing and making it unsuitable for some work conditions that require sealing; 3. The existing technology also includes butt joint support connecting joints, but this structure mostly uses U-shaped support pieces, which cannot be quickly aligned with the connecting holes during assembly or maintenance due to the bottom support surface limit, making it difficult to assemble the entire connecting part when the connecting end is slightly deformed, which seriously affects the construction efficiency; 4. Furthermore, the protruding corrugated plates are pressed into the U-shaped opening, and the bottom plate is set at a high position, making the wrench operation range narrow during installation and disassembly, which makes assembly and disassembly difficult.

[0004] To address the above-mentioned disadvantages, as a corrugated pipe field technician, the current technical problem to be solved is: how to improve the structure through technical improvement to design a steel corrugated pipe reinforced connecting structure that can improve the strength of the structure while ensuring the combined strength after multiple assemblies to avoid collapse and internal and external leakage.
