Title:
DAM CONSTRUCTION METHOD
Document Type and Number:
Japanese Patent JP2015094161
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an efficient dam construction method that uses a cable crane in all areas from a low elevation to a high elevation of a dam body.SOLUTION: A first cable crane 1 and a second cable crane 41 that is situated on the upstream side of the former are installed over a scheduled dam body construction location 59. Then, in an area with a low elevation 63 at the scheduled dam body construction location 59, a main rope 39 of the cable crane 1 and a main rope 49 of the cable crane 41 are positioned at respective locations above a horizontal cross-sectional plane of a construction work range 57, to construct a dam body 51. Next, a lower edge part 7b of a side stay 7 is shifted by sliding using a slide mechanism 21 of the cable crane 1, at the same time letting a main tower 3 rotate at its rotating part and swing toward the upstream side, thereby shifting the main rope 39 from the downstream side to the upstream side of the dam body 51 and repositioning it above a horizontal cross-sectional plane of a new construction work range 61. Then, the dam body 51 is constructed at an area with high elevation 69 at the scheduled dam body construction location 59.
