TEMPORARY SLEEPER FOR SHIELD TUNNELING WORK
PROBLEM TO BE SOLVED: To provide a temporary sleeper for shield tunneling work that may be installed as the temporary sleeper not only on an iron segment but also as is an a RC segment, even when a cross beam or an L-shaped reinforcement plate is provided on a flange of the iron segment.SOLUTION: A temporary sleeper for shield tunneling work includes a sleeper member installed transversely in a chord-form and a horizontal posture near a bottom part on an inner surface of connected segments, and a pair of right and left support brackets disposed on the inner surface of the segment to have right and left edge parts of the sleeper member mounted and supported on a top surface. The support bracket includes an inclined contact surface for bringing a bottom surface of the support bracket in contact with the inner surface of the segment, and a rail holding part for supporting an outer side of a rail bottom part provided at an outside edge part of the support bracket, the rail holding part being roughly U-shaped and facing inward. The sleeper member includes a connection piece hanging down at a roughly central part for connecting with or contacting with the inner surface of the segment, and a rail fixture for fixing an inner side of the rail bottom part to the sleeper member.SELECTED DRAWING: Figure 1
【課題】鉄製セグメントのフランジに横桁や補強Ｌ状プレートが設けられている場合であっても、鉄製セグメントに仮設枕木として設置できることは勿論、ＲＣセグメントにもそのまま設置することを可能にしたシールドトンネル工事用仮設枕木を提供する。【解決手段】接続されたセグメントの内面底部近傍に水平姿勢で弦状に横断配置される枕木部材と、この枕木部材の左右両端部を上面に載架支持して前記セグメントの内面に配置される左右一対の支持ブラケットを備え、前記支持ブラケットが、その底面を前記セグメント内面に当接する傾斜当接面と、前記支持ブラケットの外側端部に内向き略コ状をなすレール底部の外側を支持するレール保持部を具備し、前記枕木部材が、略中央部に垂下して設けた前記セグメント内面に結合又は当接される連結片と、前記レール底部の内側を当該枕木部材に固定するためのレール固定具を備えてシールドトンネル工事用仮設枕木を形成した。【選択図】図１
