Underground sky parking field and its construction manner

摘要

PURPOSE:To omit the installation, demolition and removal operation of a temporary material, to shorten the term of work largely, to eliminate scaffold operation at the time of demolition and removal operation, to improve safety and to reduce material cost without using the temporary material. CONSTITUTION:Columns 17 and beams 18, 19 are used as the shelf piles, shores, etc., of bearing members bearing external pressure to a peripheral external wall 12a while the columns 17 and beams 18, 19 of an underground multi-story parking space 8 to be built are constructed at specified positions to be built, and landslide protection wall construction for preventing the ground collapse of the peripheral external wall 12a of an excavated hole 12 is carried out. Concrete is placed on the inner circumference of the peripheral external wall 12a and an underground external wall 13 is formed, an necessary section is removed after concrete displays specified strength, and the elevator section 11, the floor section 20, etc., of the underground parking space 8 are installed, thus constructing the underground parking space 8 to be built.
