Description

Technical Field

[0001] This utility model belongs to the field of engineering construction technology, specifically relating to a prefabricated suspension protection device for communication pipelines crossing foundation pits. Background Technology

[0002] Urban communication pipelines are mainly laid underground along municipal roads. Various buildings and structures are constructed beneath these roads using the open-cut method. The excavation area often conflicts with existing communication pipelines, necessitating pipeline relocation. However, relocation projects outside the excavation area involve significant investment, and the cutting and splicing of pipeline joints can interrupt communication and disrupt normal operations. While an in-situ suspended protection relocation scheme that crosses the excavation pit can effectively solve these problems, it presents safety hazards during construction, such as collisions with construction equipment or falling objects, which could damage the suspended pipelines. Therefore, effective protection of the suspended pipelines is essential to eliminate these safety risks and ensure communication security.

[0003] Currently, there are some research achievements in China. Patent CN221196383U discloses an underground pipeline suspension protection device, proposing a technical solution that uses hanging plates, pull plates, and support plates installed on a suspension beam to protect suspended pipelines. Patent CN215928602U discloses an underground pipeline suspension protection device for open-cut pits, proposing a technical solution using a double-groove structure and suspension rods to protect suspended pipelines. These technological achievements mostly use structural steel and steel plates, proposing effective measures to protect suspended pipelines. However, these technical measures are still relatively expensive, and component reinstallation is difficult. There is room for improvement in areas such as green construction, saving project investment, and facilitating on-site construction.

[0017] See attached document Figure 1-2 A prefabricated suspension protection device for communication pipelines crossing foundation pits includes: a suspension support component 4, a cable 5, a U-shaped protective cover 6, a U-shaped connecting rod 7, and a protective cover mounting connector 9. The suspended support component 4 is fastened to the capping beam 3 of the retaining structure on both sides of the foundation pit by pre-embedded parts. The retaining structure 2 can be made of reinforced concrete bored piles, underground continuous walls or steel sheet piles, etc., for supporting the open excavation foundation pit and providing vertical support for the suspended support component 4. The capping beam 3 of the retaining structure is a cast-in-place reinforced concrete structure with pre-embedded steel bars for fixing the suspended support component. The suspended support component 4 can be made of H-beams, channel steel, steel pipes, truss structures, concrete support beams or steel wire ropes, and is rigidly connected to the capping beam 3 of the retaining structure through the reserved bars on the steel cage of the retaining structure 2.

[0018] In this embodiment, the suspension support component 4 is made of H-beams and placed horizontally. The communication pipeline 1 is tied to the lower part of the suspension support component 4 by multiple equally spaced cables 5, so that the communication pipeline 1 can be reliably suspended above the open-cut foundation pit.

[0019] In addition, a U-shaped prefabricated rigid protective cover is made using steel plates. The length of each section and the number of installations can be determined according to the ease of construction. Multiple mounting holes 1 are opened at equal intervals at the upper end of the two side plates of the U-shaped protective cover 6 from a certain position at the edge. Multiple sets of mounting holes 2 are opened at equal intervals along the longitudinal direction of the bottom plate. Each set of mounting holes 2 consists of 2 holes.

[0020] During actual installation, the U-shaped protective cover 6 is placed upside down on the suspension support component 4 and the existing communication pipeline 1. The prefabricated U-shaped connecting rods 7 with threads at both ends are passed through the two mounting holes at the corresponding positions on the bottom plate of the U-shaped protective cover 6. Then, nuts 8 are used to fasten the U-shaped connecting rods 7 to both ends, so that the U-shaped protective cover 6 is firmly fixed on the suspension support component 4 to form a whole.

[0021] The protective cover mounting connector 9 is a crossbar with threads at both ends. Its two ends pass through the corresponding mounting holes on the two side plates of the U-shaped protective cover 6. Then, the two ends of the crossbar are tightened with nuts 10 to clamp the two side plates of the U-shaped protective cover 6. After installation, a more rigid square-like protective cover is formed.

[0022] This utility model discloses a prefabricated suspension protection device for communication pipelines crossing foundation pits. A prefabricated U-shaped protective cover 6 made of steel plate is inverted and installed on the existing communication pipeline 1 that is suspended across the open-cut foundation pit. Through prefabricated installation, a roughly square protective cover is formed, protecting the existing communication pipeline 1 suspended across the open-cut foundation pit section from damage caused by collisions with construction equipment during excavation or by falling overhead objects. This ensures the safe operation of the existing communication pipeline 1 throughout the entire open-cut foundation pit construction process. The roughly square protective cover is prefabricated and easy to disassemble. When restoring the pipeline after the open-cut foundation pit construction is completed, the roughly square protective cover is easy to disassemble without damaging the communication pipeline 1. It can also be reused, and has good economic benefits.
