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.
