摘要： PROBLEM TO BE SOLVED: To provide a method of preceding waterproof construction of a bored earth-retaining wall before constructing an underground structural skeleton, allowing a cement-based material equivalent to a concrete or a mortar to closely attach to irregularities of the earth-retaining wall for preventing formation of a water path, to form no weak point resulting from joints accompanied by sheets, and not to be damaged during construction of the skeleton.SOLUTION: Before a structural skeleton of an underground structure is constructed, a waterproof construction is performed to form a water cut-off layer on a bored earth-retaining wall by spraying a fiber reinforcement cement composite with multiple fine cracks (HPFRCC) exhibiting a tensile strain of 1% or more at a material age of 28 days to a thickness of 5 to 150 mm.

摘要： PROBLEM TO BE SOLVED: To provide a method of constructing a vertical shaft, which surely steps water and can shorten the work period.
SOLUTION: In the method of constructing the vertical shaft, a shaft bottom part D in a vertical-shaft wall body 1 is cooled with ground water B accumulated in the vertical-shaft wall body 1 after the earth and sand is discharged from the vertical-shaft wall body 1, thereby freezing the entire range of the shaft bottom part D with a predetermined thickness. Subsequently, the ground water B is discharged from the vertical-shaft wall body 1, and bottom plate concrete 6 with a frozen part 4 as a base is placed above the frozen part 4 of the shaft bottom part D within the vertical-shaft wall body 1, while the shaft bottom part D is in the frozen state. A series of these operations eliminates the need for placing the bottom plate concrete 6 underwater, and further a gap is hardly generated between the vertical-shaft wall body 1 and the shaft bottom part D by freezing the entire range of the shaft bottom part D with the predetermined thickness. Accordingly, the ground water is hard to infiltrate into the vertical-shaft wall body 1, thereby quickly and surely pumping up the ground water.

摘要翻译：要解决的问题：提供一种构造垂直轴的方法，其可靠地对水进行排水并且可以缩短工作周期。解决方案：在构造垂直轴的方法中，竖直轴壁体1中的轴底部D在砂土被排出之后被积聚在垂直轴壁体1中的地下水B冷却垂直轴壁体1，从而使轴底部D的整个范围以预定厚度冷冻。随后，将地下水B从垂直轴壁体1排出，将具有冷冻部4作为基底的底板混凝土6放置在竖直轴壁体内的轴底部D的冷冻部4的上方而轴底部D处于冻结状态。一系列这些操作消除了将底板混凝土6放置在水中的需要，并且通过将轴底部D的整个范围通过将轴底部D的整个范围冻结而进一步在垂直轴壁体1和轴底部D之间产生间隙，预定厚度。因此，地下水难以渗透到垂直轴壁体1中，从而快速且可靠地抽吸地下水。版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a construction method of a grade separation, and the grade separation with a foundation formed in the ground at the side of a girder installation position.
SOLUTION: A side span girder 7 is built up above the side of an underground buried object such as a water pipe 41 or a sewer pipe 43 and jacked up by a lifting device 5. While building up a center span girder 29 above the side span girder 7, a large-bore cast-in-place pile 21 sufficiently rooted into an assumed support layer 11 is formed below the side span girder 7, and an eccentric bridge pier 25 is installed on the large-bore cast-in-place pile 21. The side span girder 7 with the center span girder 29 placed thereon is jacked down onto a temporary section of a beam part 37 of the bridge pier 25 and laid set off in a direction right-angled to a bridge axis at an installed section of the beam part 37. Further, the center span girder 29 is laid pushed out in a bridge axis direction.

摘要： PROBLEM TO BE SOLVED: To cover a water bottom side opening of a transport pipe by underwater concrete placed beforehand as quickly as possible.SOLUTION: A position of an excavation bottom face 2 where a transport pipe 5 is to be installed is first partially digged down by using a clamshell bucket 7 and the like to excavate and form a recess 6. Next, a water bottom side opening 5a of the transport pipe 5 is inserted into the recess 6. Then, a plunger 8 limiting contact of underwater concrete with water in the transport pipe 5 is put into the transport pipe 5 from a water level opening end of the transport pipe 5. Subsequently, the underwater concrete is supplied from the water level opening end of the transport pipe 5 into the transport pipe 5. Then, the underwater concrete presses the plunger 8 in the transport pipe 5 to push the plunger 8 from the water bottom side opening 5a of the transport pipe 5 into the recess 6. Thereby, the underwater concrete in the transport pipe 5 is supplied and filled into the recess 6. As a result, the water bottom side opening 5a of the transport pipe 5 is quickly covered by the underwater concrete in the recess 6.
