COFFERDAM CONSTRUCTION METHOD OF EXISTING UNDERWATER STRUCTURE AND COFFERDAM STRUCTURE OF EXISTING UNDERWATER STRUCTURE
To provide a cofferdam construction method and a cofferdam structure of an existing underwater structure applicable to the existing underwater structure for which it is difficult to make a cofferdam by surrounding its periphery and allowing time for making the cofferdam to be shortened and its installation to be easily carried out.SOLUTION: A cofferdam construction method for an existing underwater structure constructing a dry area by making a temporary cofferdam in a part of the existing underwater structure with cofferdam materials and discharging water from its inside comprises: an anchor installation step of installing two lines of anchors in the existing water structure with a specific interval in the vertical direction; a ruler installation step of installing a pair of right and left ruler materials forming a guide slit on two line of the anchors installed in the anchor installation step by joining the ruler materials at an interval of the slit; a rail installation step of installing rail members on an end part in a horizontal direction of the cofferdam member; and a cofferdam material fixing step of connecting and fixing one of the ruler materials to the cofferdam materials after press-fitting the cofferdam materials to a specific depth by sliding the rail members in the slit.SELECTED DRAWING: Figure 3
【課題】周囲を取り囲んで締め切ることが困難な既設水中構造物にも適用することができるとともに、仮締め切りにかかる時間が短く、かつ、容易に施工できる既設水中構造物の仮締切工法及び仮締切構造を提供する。【解決手段】既設水中構造物の一部を仮締切部材で締め切ってその内部を排水してドライエリアを構築する既設水中構造物の仮締切工法において、既設水中構造物に所定間隔をあけて縦方向に２列のアンカーを設置するアンカー設置工程と、アンカー設置工程で設置した２列のアンカーに、ガイド用のスリットを形成する左右一対の定規材を、スリット分の間隔をあけて接合して設置する定規材設置工程と、仮締切部材の水平方向の端部にレール材を取り付けるレール取付工程と、を備え、レール材をスリット内で摺動させて仮締切部材を所定の深さまで圧入した後、定規材の一方と仮締切部材を接合して固定する仮締切部材固定工程を行う。【選択図】図３
