Stay cable viewable intelligent beam end sealing waterproof cap structure

Abstract

The invention relates to a stay cable viewable beam end sealing waterproof cap which is arranged on a pipe orifice at the front end of a waterproof cover and comprises a waterproof cap body, wherein the waterproof cap body is of two-sectional involution type structure or multi-sectional combined type structure; a stepped hole is formed in the inner circumferential wall at the rear end of the waterproof cap; the front end of the waterproof cover stretches into the stepped hole; a first seal ring is arranged in the axial clearance of the stepped hole and the waterproof cover; a third seal ring is arranged at the front end of the waterproof cover; a second seal ring is arranged on the inner circumferential wall of a waterproof cover body; multiple annular bulged ribs are arranged on the contact surface, towards the cable body, of the second seal ring; under the hooping action of the waterproof cover body, the second seal ring deforms the multiple annular bulged ribs to annularly embrace the cable body; and a visible window is arranged on the waterproof cap body. The stay cable viewable beam end sealing waterproof cap can effectively seal the front end of the waterproof cover to play areliable protective role and can conveniently observe the inner service condition of the waterproof cap.

Description

technical field [0001] The present invention relates to an inspectable waterproof sealing protection structure at the girder end of a stay cable or a sling, and particularly relates to a waterproof cover installed at the front end of a girder end, which can be used to observe whether the inside of the girder is exposed or not during daily maintenance without disassembly. Moisture, rusted smart beam end flashing construction. Background technique [0002] Cable-stayed cables are the main load-bearing components of cable-stayed bridges, and their durability directly affects the safety, economy and reliability of cable-stayed bridges. The durability of the stay cable mainly includes the durability of the stay cable body, and the durability of the connection transition between the stay cable and the tower end and the beam end. In recent years, the durability of the stay cable system has been effectively guaranteed by measures such as hot-extruding durable high-density polyethyl...

Problems solved by technology

[0005] In addition, the sealing effect of the waterproof cap at the beam end cannot be accurately tested. The use effect of the waterproof cap still needs to be verified in practice. During the verification, the waterproof cap needs to be disassembled to observe the internal service conditions and judge the sealing effect, and repeated disassembly will cause damage to the seal
