Subway temporary ventilation pavilion and cooling tower pipeline part relocation and transformation construction method

Abstract

The invention relates to a subway temporary ventilation pavilion and cooling tower pipeline part relocation and relocation construction method which comprises the steps of relocation and relocation range determination, cooling tower pipeline relocation and relocation, new temporary pipe gallery construction, new temporary ventilation pavilion construction, old air duct and old ventilation pavilion dismantling and backfilling. A cooling tower pipeline in a newly-built project range in the old air duct is changed into an old air duct outside the newly-built project range; afterwards, a supporting wall is built in the old air duct outside the newly-built project, the supporting wall and the old air duct outside the range of the newly-built project jointly form a temporary pipe gallery in the project construction period, meanwhile, a temporary ventilation pavilion is built above the old air duct outside the newly-built project, and a ventilation system of the subway conducts air outlet and ventilation from the temporary ventilation pavilion; and finally, the old ventilation pavilion and the old air duct in the newly-built project range are dismantled, the strength of all stress nodes of the supporting wall is measured, and after the design strength requirement is met, backfilling is conducted on the open cut foundation pit. The method has the effect of shortening the temporary ventilation pavilion and cooling tower pipeline part relocation construction period.

Description

technical field [0001] This application relates to the field of subway wind pavilions and cooling towers, and in particular to a construction method for partial relocation of subway temporary wind pavilions and cooling tower pipelines. Background technique [0002] At present, with the development of underground rail transit, there are more and more new commercial complex projects next to the subway station. However, due to the incomplete urban planning in the early stage, such newly-built commercial projects next to existing subway stations often overlap in space with the above-ground wind pavilions, cooling towers and cooling tower pipelines of the subway station, so it is necessary to In front of the commercial complex of the subway, complete the relocation of the wind pavilion, cooling tower and cooling tower pipeline of the subway where the space overlaps. Due to the subtropical geographical environment of most developed cities in southeast my country, the window perio...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that when the air duct and the cooling tower pipeline are partly within the scope of the new project, the construction period of the temporary wind pavilion and the relocation of the cooling tower pipeline is long and the construction period is urgent.
