摘要： PURPOSE: To construct a retaining wall safely and surely in the ground where it is impossible to construct the retaining wall from the face of the ground, and to hold down the open-cut part from the face of the ground to none or the minimum so as to exert no bad influence to the ambient environment. CONSTITUTION: A sheathing structure comprises a retaining wall 20 formed on the lower ground of an underground installation 16 and an upper structure 22 tunnel structure fixedly provided on the upper part of the retaining wall 20. The retaining wall 20 is formed as a connecting structure 28 having a continuous internal space by connecting two, upper and lower tunnel structures 26 constructed at suitable spaces to each other. A water stop body 48 is disposed side by side with the lower side of the connecting structure 28. The upper structure 22 connects plural laterally arranged tunnel structures 52 in the upper opposite position of the retaining wall 20 to one another to construct a connecting structure 54 having a continuous internal space, and both ends of the connecting structure 54 are fixed to the upper part of the retaining wall 20. Accordingly, it is possible to construct an underground structure without construction from the face of the ground in an area where construction from the face of the ground is impossible.

摘要： PURPOSE:To easily form an underground space by providing a connecting part in which segments of adjacent tunnels are mutually connected every prescribed interval in the axial direction of a plurality of tunnels of an underground structure, and a non-connecting part between the connecting parts. CONSTITUTION:Segments 12, 14 are mutually connected according to the excavation of a shield excavator to form a plurality of tunnels 16 to enclose a prescribed bedrock having a rectangular section by the tunnels 16. The segments 12, 14 of the adjacent tunnels 16 are structurally connected to each other every prescribed interval in the axial direction of the tunnels 16. The bedrock enclosed by the tunnels 16 is excavated to form an underground space 18, and concrete of a quantity according to a design condition is filled in a part or all of the tunnels 16 to line 82 the inner wall of the underground space 18. A part or all of the tunnels 16 are utilized as spaces for various purposes. Thus, the underground spaces 18 are continued to each other to form a lining structure 10, and the water stopping property and safety of the whole underground structure 10 can be ensured.

摘要： PURPOSE:To hold down equipment manufacturing cost and equipment weight or segment weight and comply with construction environment in large cities, such as security of a shaft construction site and minimize an overburden without any troubles and expand and reduce the cross section of tunnels and take proper measures for the installation of facilities, such as branching or joining and an emergency parking lot for every definite spacing and prevent the capacity of a shield driving machine from being increased excessively, and excavate the natural ground between the tunnels, taking cut-off measures at the same time. CONSTITUTION:In a tunnel connection method, which excavates and expands the natural ground between adjacent tunnels excavated with a specified spacing and connects each of the tunnels structurally, a sheathing board 28 is pressed into the natural ground between the tunnels from a segment 12 which constitutes at least one tunnel and covers the natural ground between the tunnels so that the earth may be retained. The natural ground surrounded by the sheathing boards 28 is excavated from the segment 12 so that the tunnel may be expanded. Each of the segments 12 is connected with a shape steel material 14.

摘要： PURPOSE:To accelerate the consolidation of a cohesive soil ground by piercing the cohesive soil ground with a cohesive soil layer to form latticed drain ditches in plane reaching a lower water permeable layer, and draining underground water forcedly from the drain ditches to lower the ground-water level. CONSTITUTION:A cohesive soil ground (n) is pierced with a cohesive soil layer (n1) to reach a lower water permeable layer (n2), and latticed drain ditches 1 are formed in succession in plane. Underground water is forcedly drained by underwater pumps P and P. etc. from the drain ditches 1, and the ground-water level W is lowered to the consolidated phenomenon of the cohesive soil layer (n1) is accelerated. In addition, the drain ditches 1 are constituted of latticed thin type ditches 1a, circular holes 1c, 1b and 1b excavated in the intersection parts and midst parts, and the drain ditches 1 are filled with water permeable materials. The ultimate outside drain ditches 1A and 1A are excavated deeper than another drain ditches 1, and impermeable members 7 and 7 are provided over the full lengths of them. In addition, condenser wells (m) are excavated in the outside of a section of the cohesive soil ground (n) surrounded by the drain ditches 1, and the underground water pumped from the cohesive soil ground (n) is returned to normal circulation.

摘要： PURPOSE:To construct a tunnel for two-track or four-track lines by excavating the tunnel in square section with a front and a rear shield machines that are expandably connected each other and are equipped with a plurality of cutter units, and with screw cutters that are provided to the side of the shield machines. CONSTITUTION:A shield machine A is slidably fitted with guide plates thereof to the side face of a precedent underground space B constructed in advance. The ground above and below the precedent undertground space B are dug and excavated earth and the like are prevented from intruding into the guide plates 2 with seal packing 4, and are discharged outside as they are conveyed toward cutters 6. A front shield machine 1a and a rear shield machine 1b are made to expand and contract during the progress of excavation, and adjustment on meandering of the excavation and widening and reducing of the width of the tunnel are made thereby. Lining is made with segments (a) placed one after another, and thereby a succeeding underground space C is constructed. By such a method, a large scale structure can be constructed underground in a great depth.
