Description

Technical Field

[0001] This invention relates to an improvement in the cable sleeve system technology for suspension bridges, belonging to the field of bridge engineering, and particularly to a cable sleeve system for suspension bridges. Background Technology

[0002] The entire structure of a suspension bridge is supported by the main cable, which is one of the most critical load-bearing components and cannot be replaced. Therefore, the protection of the main cable is a key issue that needs to be considered and addressed in the design, construction, and maintenance of suspension bridges. To prevent the main cable from being directly exposed to rain and snow for extended periods, thus affecting its service life and consequently the bridge's lifespan, cable sleeves are typically installed on the main cable between the main tower saddle chamber and the end cable clamp, and between the anchor chamber and the end cable clamp. However, existing cable sleeves often use sealant to directly seal the joint between the upper and lower halves. After years of exposure to wind, sun, rain, snow, and frost, rainwater and snowmelt can easily seep into the cable sleeve from the joint, corroding the main cable. Furthermore, the water that seeps into the cable sleeve cannot drain, further damaging the main cable. Under changes in load and temperature, the length of the cable sleeve will elongate and contract to a certain extent. The existing cable sleeves do not elongate and contract much with the main cable, which cannot meet the requirements of the elongation and contraction of the main cable of a long-span suspension bridge. When maintaining the main cable and cable clamps, operators carrying tools walk directly on the arc-shaped cylinder of the cable sleeve, which can easily lead to accidents such as slipping and falling. The existing cable sleeves are thin-walled cylindrical structures, and the cable sleeve cylinders are also prone to deformation due to the weight of personnel stepping on them, which further affects the sealing effect of the upper and lower half of the cable sleeves and also affects the safety of the bridge.

[0003] Chinese patent application CN201620660393.3, filed on June 28, 2016, discloses a polyurethane cable sleeve for the main cable of a suspension bridge. The cable sleeve body is molded from polyurethane, and each end of the cable sleeve body has outwardly folded flanges. These flanges are fixed to corresponding components of the suspension bridge. This utility model's cable sleeve body, molded from polyurethane, features high structural strength, tear resistance, and large deformation capacity, enabling long-term service in suspension bridge engineering. It is durable, has a long service life, good stability, high reliability, and good economy. It can be used with both main cables with small and large expansion / contraction, making it highly practical. However, the aforementioned prior art does not solve the problem of poor sealing performance in existing cable sleeves.

The bottom of the lower cable sleeve and the lower cable sleeve clamp have threaded holes, and the threaded holes are fitted with sealing gaskets and screw plugs. When water accumulates in the cable sleeve clamp assembly and the cable sleeve assembly, the screw plugs and sealing gaskets can be removed to drain the water and keep the inside of the cable sleeve dry. Therefore, this design allows the main cable to remain dry, making it safer. Attached Figure Description
