Description
Technical Field
The utility model relates to a parking planning correlation field, more specifically say, relate to a rectangle push pipe tube coupling that can assemble.
Background
With the advance of urbanization construction, the ground buildings of various cities are increased, and particularly, the ground buildings in the core areas of most of the cities are more and more dense. The dense ground building also brings more difficulties to the construction of the underground structure, and the frequent excavation of urban roads also brings much inconvenience to the lives of citizens. The pipe jacking technology is a trenchless construction method, is a trenchless or trenchless pipeline burying construction technology, and is generally used for municipal engineering. The excavation method has the advantages that the excavation is not needed or is less, so the influence on city construction during construction is small, the road traffic is not blocked, the vehicles can normally pass, and the damage and the influence on ground infrastructure can be reduced. So most municipal works select the pipe jacking method at present.
The pipe jacking method is characterized in that pipe pieces prefabricated in a factory are transported to a construction site, installed in a working pit, pushed into the soil by means of jacking force generated by jacking equipment and overcoming friction force between a pipeline and surrounding soil, and the steps are repeated until the jacking work of the whole section of tunnel is completed. But as the pipe jacking technology becomes more mature, the size of the pipe piece is larger and larger, so that the transportation of the pipe piece becomes difficult.
