Problems solved by technology
In the existing steel pipe relay room, it is inconvenient to carry out anti-corrosion measures after the construction is completed
After the pipe jacking construction is completed, the internal oil cylinder and fixing device are not easy to disassemble
After the disassembly is completed, the workload of anti-corrosion is too large, and the anti-corrosion effect is not good, and it will fall off after a long time

Embodiment Construction
[0019] Such as figure 1 , 2 As shown, it is a steel-concrete pipe anti-corrosion relay room, including a front-end pipe assembly 1 and a rear-end pipe assembly 2. The front end of the rear-end pipe assembly 2 is inserted at the rear end of the front-end pipe assembly 1. A bird-shaped sealing ring 8 is arranged between the pipe assemblies 2 , and a pumping station 9 is connected in the pipe assembly 2 at the rear end. The front end tube assembly 1 includes a front steel plate outer tube 1-1 and a front cement inner tube 1-2, the front cement inner tube 1-2 is connected in the front steel plate outer tube 1-1, and the rear end tube assembly 2 includes a rear steel plate outer tube 2 -1 and the back cement inner pipe 2-2, the back cement inner pipe 2-2 is connected in the back steel plate outer pipe 2-1.
[0020] A step 7 is set on the outer periphery of the front end of the rear end pipe assembly 2, and an O-shaped top ring 3 is arranged on the step 7 of the rear end pipe asse...

A reinforced steel anti-corrosion relay relates to the technical field of engineering construction, in particular to a detachable relay. The reinforced steel anti-corrosion relay comprises a front end pipe assembly, a rear end pipe assembly and an O-shaped ejecting ring; an oil cylinder backrest bracket is connected in the front end pipe assembly and is provided with a plurality of oil cylinders; each oil cylinder is fixed on the oil cylinder backrest bracket by an oil cylinder fixing plate; a telescopic end of each oil cylinder is connected with the O-shaped ejecting ring respectively; a pump station is connected in the rear end pipe assembly; the O-shaped ejecting ring comprises 6-20 groups of arc ejecting frames same in structure; the oil cylinder backrest bracket comprises 6-20 groups of arc supports same in structure. The O-shaped ejecting ring is divided into a plurality of groups of arc ejecting frames same in structure, the oil cylinder backrest bracket is divided into a plurality of groups of arc supports same in structure, after construction, internal parts are taken out and conveyed, the detaching parts (the O-shaped ejecting ring and the oil cylinder backrest bracket) are equally divided into a plurality of same parts so as to reduce the weight during detaching.
Description
technical field [0001] The invention relates to the technical field of engineering construction, in particular to a detachable relay room. Background technique [0002] Long-distance pipe jacking refers to the pipe jacking construction where the continuous advancing distance of each section is more than 200m-300m, and some can reach 800m-1500m. Due to the long continuous push distance, there are many differences from ordinary pipe jacking construction. Although mud lubrication measures can be used to reduce jacking friction resistance for long-distance pipe jacking, no matter how much the jacking force is reduced, it is subject to certain restrictions. During the jacking process, when the back strength or the bearing capacity of the pipe is limited, the entire jacking section can be divided into several sections and relay jacking can be used to extend the jacking distance. [0003] The relay room is a relay jacking working room set in the middle of the jacking pipe section....
