OPEN TYPE SAND PREVENTION DAM AND METHOD OF CONSTRUCTING THE SAME
Document Type and Number:
Japanese Patent JP2015063841
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an open type sand prevention dam and a method of constructing the open type sand prevention dam capable of trapping boulders and drift woods flown down in a river as a bank to prevent the boulders and drift woods from being scattered.SOLUTION: There is provided an open type sand prevention dam which is constructed in a river in a width direction X of the river. The open type sand prevention dam includes: plural three-dimensional structures 2 which are constructed between sleeve parts 5 constructed at both sides of the river; and a planar structure 3 which is constructed aligned with the plural three-dimensional structures 2. The three-dimensional structure 2 includes: upstream column members 21 which are disposed at the upstream side A of the river; downstream column materials 22 which are disposed at the downstream side B; and a sheath pipe 10 which is an end part of a beam material of the planar structure into which an insertion pipe is inserted. The planar structure 3 includes: column members 31 extending upward from a streambed; and a planar structure beam member 32 to which the column members 31 are attached. End parts of the planar structure beam member 32 are inserted into the sheath pipes 10. The column members 31 and the upstream column members 21 are aligned with each other in the flowing direction of the river.
