The present invention relates to a shaft construction method for the elevator extending station with mat base by a more particularly to the construction in the excavation state improve the installation environment, and the access equipment glass, and even when there is no space in the basement of the building It relates to a shaft construction method for the elevator based on extended operation using the mat that can be constructed.
The present invention according to the shaft construction method for the elevator extension operation using the mat basis to extend the elevator shaft is installed at the outermost part of the building into the ground, going to reinforce the wall around which the elevator hoistway adjacent ones of the exterior of the building a first drilling step of drilling the section to the construction part and an underground parking lot adjacent to the shaft portion to be extended; Construction of the underground parking lot and the underground shaft of the base mat and mat base installation step of synthesizing the file mat with the base exposed by the second drilling step in the process of construction of the mat base; Underground construction comprising: a hoistway wall construction the wall for communicating with the shaft of the mat base underground the load transmitted to the lower shaft through the ground of the wall of the building; File cutting step of obtaining an underground shaft space by cutting a file located in the basement space to be installed in the elevator shaft after the wall construction phase; And, underground car park construction step including columns and slab construction of the underground parking lot; Using the carpet base, it characterized in that it comprises a shaft to provide a construction method for the elevator extending from station.
