摘要： PROBLEM TO BE SOLVED: To cut off water, corresponding to a joint opening amount of a joint, by forming a groove on a tip face of a following concrete wall side on a preceding concrete wall, arranging a water expansion seal material in the groove and giving a placing joint to the following concrete wall. SOLUTION: The underground water entering a construction joint H from the natural ground due to opening of the construction joint H is led into a water cut-off space 22, and a water expansion seal material 15 is expanded due to the reaction with the underground water to block the water cut-off space 22. Further, since the construction joint H is blocked and expansion magnification of the water expansion seal material 15 is selected properly, water can be cut off even when a joint opening amount of the construction joint H is large. In this case, it is unnecessary to predict a joint opening amount of the construction joint H in advance and it is possible to correspond flexibly in accordance with the construction joint opening amount. Since the water expansion seal material 15 is expanded toward a water cut-off projecting part 23 side only in a groove 21, it is possible to concentrate expansion pressure of the seal material 15 on the water cut-off projecting part 23 side. Consequently, it is possible to position and fix the water expansion seal material 15 easily at low cost.

摘要： PROBLEM TO BE SOLVED: To cut off water by corresponding to a joint opening amount of a construction joint by forming a groove on a tip face on a following concrete wall side and arranging a bentonite water cut-off material expanding due to the reaction with water in the groove to place and join a following concrete wall. SOLUTION: A bentonite water cut-off material 15 is used as a water cut-off material and expands due to the reaction with underground water when the underground water enters a construction joint of an underground concrete structure. Furthermore, the construction joint is blocked due to clogging of the construction joint, and the construction joint is blocked to cut off water even when a joint opening amount of the construction joint is large. In this case, it is unnecessary to predict the construction joint opening amount of the construction joint in advance to correspond flexibly in accordance with the construction joint opening amount. Even when a concrete wall is wet, the bentonite water cut-off material 15 reacts with water, expands, and adheres closely on the concrete wall to cut off water. Consequently, it is possible to position and fix the bentonite water cut-off material 15 easily at a low cost by arranging the bentonite water cut-off material 15 in a groove 21.

摘要： PROBLEM TO BE SOLVED: To reduce the construction cost of a water-shielding layer. SOLUTION: A water-shielding layer is constructed by using bentonite crude ore in place of powdery bentonite on the market. The bentonite crude ore is granular bentonite before being purified to the powdery bentonite. The water- shielding layer is produced by mixing and stirring the bentonite crude ore and soil. The preferable grain size of the bentonite crude ore is

摘要： PROBLEM TO BE SOLVED: To provide a slope drilling machine and its method which can easily position a drilling machine on a slope surface and improve the efficiency of a drilling work. SOLUTION: A slope drilling machine 1 is equipped with a runable truck 2, an inclinable mast provided on the truck 2, and a drilling device 4 mounted so as to be movable along the mast 3. In the case where a hole for setting a lock bolt is drilled on a slope 14 using the slope drilling machine 1, the truck 2 is run to a place near the slope 14, and the mast 3 is tilted about parallel to the slope and held, and the drilling device 4 is made opposite to the slope 14 and moved along the mast 3 and positioned at the first drilling position to carry out drilling. When the first drilling ends, the drilling device 4 is moved along the mast 3 and positioned at the next drilling position to carry out drilling. After that, a similar operation is repeated.

摘要： PURPOSE:To prevent the occurrence of a layer having excessive strength even if ground is constituted of a plurality of different soils of layers by adjusting a mixing amount of cement slurry to the ground, concentration of the cement slurry and etc. CONSTITUTION:The depth of every layer of ground is measured in advance. Discharge and driving hours of a conveying pump 11, a water pump 28 and a muddy water pump 30 for obtaining optimum cement slurry for every layer in each depth are measured in advance. For example, in the case stirring wings 17 reach a sandy soil layer having certain depth, composition ratio of cement slurry is adjusted by adjusting discharge, etc., of the water pump 28. The cent slurry is mixed by a static mixer 27 and is injected to the sandy soil layer from the stirring wings 17. In also a viscous soil layer, an intermediate layer, etc., similarly, they are so adjusted that the cement slurry has optimum composition ratio.

CONSTITUTION:Components 7 is introduced and stocked in a storage bin 8 from a truck 25 which has transported the components 7 from a shaft base 9 on the ground to a base 11, through a material filling pipes 10 and a material press-feed pipe 12. Then the components 7 are delivered from the storage bin 8 by means of a conveyer device 14, and are then shifted onto a material stocker 13. Then, they are introduced into a batches plant 20 by means of a belt conveyer 23, and the components are respectively weighed and are kneaded so as to produce concrete. A reinforcement cage is assembled in a form 24, and then the concrete is placed therein. Then after steam curing in a steam curing chamber 22, a segment A is parted and is then cured underwater. Further, the ground in a tunnel 4 is excavated, the segment A is cylindrically laid in the excavated tunnel 4a by means of an elector mechanism in a shield machine 3. The above-mentioned steps are repeated.
