METHOD FOR CONSTRUCTING PIPE TYPE STRUCTURE

摘要

PURPOSE: A construction method of a tubular structure is provided to easily construct the tubular structure since a block wall of a closed loop shape, which forms a slope corresponding to an inner wall surface or an outer wall surface, is detachably formed so that a form can be installed in a direction perpendicular to the ground surface. CONSTITUTION: A construction method of a tubular structure is as follows. Auxiliary blocks are installed on a basic concrete structure(42) as one layer to form an auxiliary block wall. Connecting blocks are installed on the basic concrete structure on one layer, a pair of connecting blocks are fixed to the auxiliary block to form a pair of connecting block walls on both sides of the auxiliary block wall. An intermediate block is installed on the basic concrete structure to form an intermediate block wall. A closed loop structure is formed on outer side of a block wall. The closed loop structure comprises an outer surface of a closed loop shape perpendicular to the ground surface and an inner surface of a closed loop shape making contact with the outer surface of the block wall.
