Demolition method of basement of building using underground structure as support

摘要

The present invention relates to a demolition method for a basement of a building using an underground structure as a support and, more specifically, to a demolition method for a basement of a building in a downtown area, capable of demolishing a basement of a building by using an underground structure as a support without using an additional device or an additional structure by using the underground structure of the building to be demolished in a downtown area as a structure supporting earth pressure. According to the present invention, the demolition method for a basement of a building using an underground structure as a support can reduce demolition costs and demolition periods by supporting the earth pressure using a part of the basement to be demolished without using the additional structure or the additional device when demolishing the basement unlike a conventional art. The demolition method for a basement of a building using an underground structure as a support can prevent earth and soil in a periphery or underground water from flowing into the basement when demolishing an outer wall of the basement by demolishing the basement after constructing grouting for demolishing a basement on the outside of the outer wall of the basement. Moreover, the demolition method for a basement of a building using an underground structure as a support can require low costs using a kind of fly ash generated in a thermoelectric power plant.
