Description

Technical Field

[0001] This utility model relates to the field of rectangular jacking pipe technology, and in particular to F-shaped steel socket rectangular jacking pipe. Background Technology

[0002] As cities expand and populations increase, the demands on urban infrastructure capacity for transportation, energy, and water supply and drainage have risen significantly. To alleviate traffic congestion, more underground rail transit systems are needed. To meet the growing water demand and sewage treatment requirements, larger diameter and longer-distance reinforced concrete pipes for water supply and drainage are required. F-type steel-socketed rectangular jacking pipes, with their large cross-sectional area utilization and excellent mechanical properties, are better suited to these large-scale and high-standard infrastructure construction needs. They can be used to construct underground integrated pipe corridors, centrally lay multiple pipelines, and achieve intensive development of urban infrastructure. Simultaneously, with increasingly scarce urban land resources, more efficient use of underground space is required. F-type steel-socketed rectangular jacking pipe construction technology can complete the laying of underground reinforced concrete pipes without occupying a large amount of ground space, providing more conditions for the planning and utilization of urban above-ground space. In urban centers, rectangular jacking pipe construction can build underground passages and drainage reinforced concrete pipes beneath busy streets, avoiding traffic congestion and disruption to commercial activities caused by open-cut construction, while also protecting the city's historical features and cultural heritage.

[0003] The structure of F-type steel socket rectangular jacking pipe includes a pipe body, F-type steel socket, connecting steel ring, rubber sealing ring, and spigot. In some areas with complex geological conditions, traditional construction methods face many difficulties and safety hazards. By adopting appropriate construction technologies and equipment, such as using earth pressure balance jacking machines in soft soil areas and slurry balance jacking machines in areas with abundant groundwater, and combining effective foundation treatment and waterproofing measures, F-type steel socket rectangular jacking pipe can better adapt to these complex geological conditions, reduce construction risks, and ensure the safe and smooth progress of the project. However, rigid joints require on-site welding and a large number of bolts for fixing, which is time-consuming, while flexible joints also rely on repeated manual adjustments for alignment, resulting in low installation efficiency.

At the same time, the bottom left side of the U-shaped plate 6 is engaged in the groove at the top of the fixing plate 8. Then, the T-shaped plate 9 at the top of the fixing plate 8 is slid to the left so that it fits against the bottom left side of the U-shaped plate 6. At this time, the positioning post 10 will pass through the groove 7, and the fixing effect is achieved by the nut 11. This facilitates the installation of the reinforced concrete pipe 1, enables quick connection, reduces adjustment time during installation, improves installation efficiency, and ensures the accuracy and stability of the connection, avoiding the problem of poor sealing caused by installation position deviation.

[0042] The reinforced concrete pipe 1 is protected by protective sleeve 1 201 and protective sleeve 203. The positioning post 204 at the top of protective sleeve 203 engages with the positioning hole 202 at the bottom of protective sleeve 1 201 to achieve initial fixation. Then, the sliding block 208 is slid, so that the short plate 205 is engaged into the groove on the left side of the sliding block 208. Finally, the engaging post 210 passes through the hole 209 and engages with the arc groove 206 to achieve fixation. This can protect the reinforced concrete pipe 1, effectively prevent damage to the reinforced concrete pipe 1 from external factors, extend the service life of the reinforced concrete pipe 1, reduce the adjustment time during installation, and improve installation efficiency.
