SUSPENTION METHOD FOR BURIED STRUCTURES

摘要

PURPOSE: A suspension method for an obstruction is provided to improve workability and stability of a task and to prevent a damage caused by sagging of the obstruction. CONSTITUTION: A suspension method for an obstruction comprises as follows. An upper support unit (100) is installed on the upper part of an obstruction (1). The side part of the obstruction is excavated, and an edge region of both lower sides of the obstruction is preliminarily excavated. The lower part of the obstruction is bored in a width direction so that a connection member insertion hole is formed. A support unit (200) is individually mounted on the edge of both lower sides of the obstruction. The support unit and the upper support unit are connected by an upper and lower direction connection member (300). A pair of the support unit is connected by a width direction connection member. The lower part of the obstruction is excavated.
