Title:
CONSTRUCTION METHOD OF DAM BODY, AND CONVEYANCE DEVICE
Document Type and Number:
Japanese Patent JP2023170159
Kind Code:
A
Abstract:
To provide a construction method of a dam body and a conveyance device allowing efficient construction work of the dam body.SOLUTION: The construction method of a dam body uses a concrete conveyance device having multiple conveyance pipes, multiple conveyance pipe receiving stringers and multiple columns. The conveyance pipe includes a first conveyance pipe unit 10A and a second conveyance pipe unit 10B connected to a lower part of the first conveyance pipe unit 10A. The conveyance pipe receiving stringer includes a first receiving stringer 20A facing the first conveyance pipe unit 10A, and a second receiving stringer 20B connected to the first receiving stringer 20A and facing the second conveyance pipe unit 10B. The construction method includes the steps of: releasing the connection of the second conveyance pipe unit 10B to the first conveyance pipe unit 10A; releasing the connection of the second receiving stringer 20B to the first receiving stringer 20A; and removing the second conveyance pipe unit 10B and the second receiving stringer 20B.SELECTED DRAWING: Figure 7
