SLEEPERS FIXING STRUCTURE INSTALLED INSIDE SHIELD PIT
PROBLEM TO BE SOLVED: To prevent sleepers which are installed in segments inside a shield pit from rolling.SOLUTION: A structure of fixing sleepers inside a shield pit according to the present invention is constituted of: a shield pit T that is composed of a plurality of annular segments SG which is constructed on the inner circumference of the drilling pit by a shield machine and mutually fastened; a plurality of sleepers 15 installed in the longitudinal direction of the shield pit T and formed so as to cross over an arcuate inner circumferential surface of the segments SG; each of rails R1 which is laid in the longitudinal direction of the shield pit T and eccentrically to the sleepers 15 and on which a transport truck for transporting constructional elements including segment constituting members runs; and each movement blocking member A that is composed of a protruding member 20 which is fitted in a grout hole GH of the rails laying side formed on each of the segments SG and which protrudes from an inner circumference of the segments SG and a plate member 21 interposed between the end portion of the sleepers 15 at the protruding member 20 side and the protruding member 20, and that prevents sleepers 15 from moving to the peripheral direction of segments SG.SELECTED DRAWING: Figure 4
【課題】シールド坑内のセグメントに設置された枕木のローリングを防止する。【解決手段】シールド掘進機による掘削坑の内周に構築され、相互に締結された複数の円環状のセグメントＳＧで構成されるシールド坑Ｔと、セグメントＳＧの弧状の内周面に掛け渡すようにしてシールド坑Ｔの長さ方向に複数設置された枕木１５と、枕木１５に偏心してシールド坑Ｔの長さ方向に敷設され、セグメント構成材を含む部材を運搬する運搬台車が走行するレールＲ１と、セグメントＳＧに形成されたレール敷設側のグラウトホールＧＨに嵌め込まれてセグメントＳＧの内周面から突出した突起部材２０、および枕木１５の突起部材２０側の端部と突起部材２０との間に介在配置された板状部材２１を備え、枕木１５のセグメントＳＧの周方向への移動を阻止する移動阻止部材Ａとで構成する。【選択図】図４
