摘要： PROBLEM TO BE SOLVED: To enable low-cost excavation while allowing the barrel part of an excavator for excavating a tunnel widened relative to a basic circular cross section to have a simple composition. SOLUTION: The cylindrical shell of a shield body 1 capable of expansion and contraction corresponding to the shape of a tunnel is separated and composed of a fixed barrel 4 on the side of a long circular arc and a widened barrel 5 on the side of short circular arc. The fixed barrel 4 is formed with a guide surface 8a for guiding a slide member 7 installed in such a manner as to be extended from both end parts of the widened barrel 5 to the side of the fixed barrel 4. A widening jack 9 is installed so as to move the widened barrel 5 in an expansion-contraction direction orthogonal to the axial center O of the tunnel. The shape of a segment 31 assembled within the shield body 1 is taken as an approximately circular cross section having parallel planar walls 32 parallel to each other at the normal excavation and taken as an oval cross section wherein the planar walls 32 are extended at the widening excavation.

摘要： PROBLEM TO BE SOLVED: To provide a method of constructing widened tunnel by which a widened section having a prescribed extent can be constructed efficiently on one side of the main body section of a tunnel by exerting little bad influence upon the surrounding ground simultaneously with the excavation of the main body section of the tunnel by means of a shield machine.
SOLUTION: The main body section and widened section of the tunnel are simultaneously excavated over the full length of the tunnel by means of the shield machine provided with a cutter head for excavating the main body section and a small-diameter cutter head for excavating the widened section on one side the cutter head. When the widened section is not constructed on one side of the main body section of the tunnel, the small-diameter cutter head is moved downward by rolling the shield machine and, at the same time, the widened section excavated by means of the small-diameter cutter head is filled up with a space stuffing material. When the widened section is constructed on one side of the main body section in a communicative state, the small-diameter cutter head is moved to the side section side of the main body section of the tunnel.

摘要： PURPOSE:To make it possible to joint protective pipes with low pressing force depending on the curve of tunnel without causing damage on the end face thereof by providing a coupling member for coupling a frame truck detachably with a protective pipe unit truck, a presser board for pressing the protective pipe unit on the rear end face thereof, and a telescopic means for telescoping the presser board back and forth. CONSTITUTION:A track car C is traveled to carry a protective unit mounting truck B into a tunnel T. A track L is then clamped by a clamp means 11 to secure a presser unit A onto the track L and to release a coupling bar 12. When a press jack 2 is operated to advance a presser board 6, a shock absorber 9 applied on the front face of the presser board 6 abuts on the rear end face of a cable protective pipe unit 7 mounted on the truck B and drives the unit 7 along with the truck B. Consequently, each cable protective pipe 7a is embedded, at the leading end thereof, into a filler 24 with the protective pipe 7a being projected rearward from an end formwork 23 and fit in a corresponding rear end socket body 18 of the unit 7 thus coupling front and rear protective pipes 7a, 7a.

摘要： PURPOSE:To make it possible to jack and bury a pipe by supporting a succeeding pipe in a state positioned accurately and easily at the rear end of a buried pipe when jacking and burying pipes underground one by one from a shaft. CONSTITUTION:After having jacked and buried a pipe Pa underground by means of a jack 4, a movbale pipe receiving base 6c of a front side pipe receiving device 6 is placed into contact with the both sides at the rear end of the pipe Pa, thereby measuring a rear side pipe axis of the buried pipe Pa. The both sides at the front end are supported with the movable pipe receiving base 6c which is moved to the position whose movement variable is equivalent to the measurement variable while a movable pipe receiving base 7c of a pipe receiving device 7 at the rear side is adjusted so that a pipe core of a succeeding pipe Pb may aligh with the center of a contact frame 4b of the jack device 4 when the succeeding pipe Pb is loaded on the movable pipe receiving base 7c. Then, after the succeeding pipe Pb is loaded on the front and the rear side pipe receiving devices 6 and 7, the succeeding pipe Pb is connected to the buried pipe Pa by driving the jack device 4.
