System and method for moving and assembling the upper section of prefabricated underground passage

Abstract

The invention provides a transferring and assembling system and method for an upper section of a prefabricated underground passage. By adoption of the transferring and assembling system and method, the problem that during construction of an underground passage project with a small construction site and strict environment protection requirements, the control difficulty of safety risks during large-scale hoisting construction on the site is high is solved. The transferring and assembling system comprises supporting main bodies, a self-propelled sliding rail, vertical adjustment mechanisms and horizontal adjustment mechanisms, wherein the self-propelled sliding rail is mounted on a structural base plate on the lower portion of the underground passage, the supporting main bodies are arranged above the self-propelled sliding rail, the vertical adjustment mechanisms are mounted at the top ends of the supporting main bodies, and the horizontal adjustment mechanisms are mounted on the side faces of the supporting main bodies. The transferring and assembling method comprises the steps that the transferring and assembling system is mounted in an inner cavity of the lower structure, which is jacked in position, of the underground passage; the upper section of the underground passage is jacked and transferred in position; the upper section, which is jacked in position, of the underground is placed on the corresponding lower section and connected with the lower section; prestress tensioning is conducted section by section, and the upper section and the lower section are connected to form the whole underground passage structure; and casing soil above the underground passage structure is backfilled, and an original ground road section is recovered.

Description

technical field [0001] The invention relates to the technical field of underground engineering construction, in particular to a transporting and assembling system and method for the upper section of a prefabricated underground passage. Background technique [0002] At present, the prefabricated underground passage structure is mostly constructed in the way of factory prefabrication → overall segmental hoisting on site → applying prestress and connecting them into a whole. The construction of the underground passage structure, and for the prefabricated underground passage structure located in the core area of ​​the city, due to its heavy segmental weight, the requirements for hoisting equipment, on-site work space and construction organization are relatively high. The construction technology and hoisting equipment are not conducive to improving the quality of project construction, but also increase the difficulty of controlling the safety risks of large-scale hoisting constru...

AI Technical Summary

Problems solved by technology

[0003] For the construction of underground passages with narrow construction sites and strict environmental protection requirements, the weight of the segmented prefabricated components of the underground passage structure is still very large, and it is difficult to control the safety risks of large-scale hoisting construction on site
