Inhaul cable protective sleeve with functional element and construction method thereof

Abstract

The invention discloses an inhaul cable protective sleeve with functional elements and a construction method thereof. The protective sleeve comprises an inner layer pipe, an outer layer pipe, reinforcing ribs fixedly arranged between the inner layer pipe and the outer layer pipe and cavity channels between the adjacent reinforcing ribs, and the inner layer pipe, the outer layer pipe and the reinforcing ribs are all made of plastic; the cavity channel penetrates through the two ends of the outer-layer pipe where the cavity channel is located. At least two sections of outer-layer pipes are arranged at intervals, and annular grooves are formed between the opposite end parts of the adjacent outer-layer pipes; a functional element is installed in the annular groove and connected with the outer-layer pipes at the two ends in a sealed mode. According to the inhaul cable protective sleeve with the functional element and the construction method of the inhaul cable protective sleeve, machining is easy, the sealing performance is good, and compared with the prior art, the inhaul cable is light in weight and small in cross sectional area, and the performance of the inhaul cable is not affected.

Description

technical field [0001] The invention relates to the field of drag cables for bridges, in particular to a drag cable sheathing tube with functional elements and a construction method thereof. Background technique [0002] At present, according to more and more architectural structures due to their unique shapes, they have become part of the local style. In order to reflect the structural characteristics and modeling characteristics of bridges and other buildings at night, functional elements such as lights have been added to the cables. Become a trend and an urgent need. [0003] In the prior art, there are some structures and methods for adding functional elements to the bridge cables, for example: the first one is to install directly on the outside of the bridge cables by using structures such as hoops. This way makes the functional elements The wires or pipelines are exposed outside the cable body, which affects the appearance of the cable on the one hand, and is easy to ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above problems, the present invention provides a cable sheath tube and cable structure, which aims to solve the difficulty of processing and poor sealing performance of the existing cable sheaths with functional elements. The casing and other structures lead to the increase of the weight and cross-sectional area of ​​the cable, which affects the performance of the cable and other issues
