<P>PROBLEM TO BE SOLVED: To suppress ground subsidence on a ground surface side during construction of an underground structure such as an under-road/under-track crossing structure, without use of a chemical feeding method. <P>SOLUTION: In a structure of an underground structure such as an under-road/under-track crossing structure, opposed plate-like members 530 are buried toward a ground surface side along both lateral sides on the top surface side of the underground structure that forms space in the ground; a pipe roof 520 is provided between the opposed plate-like members 530; and an upper end side of the plate-like member 530 positioned on the ground surface side goes over the pipe roof 520 so as to be elongated to a section between the pipe roof 520 and the ground surface. <P>COPYRIGHT: (C)2012,JPO&INPIT |
