摘要： PROBLEM TO BE SOLVED: To provide granular improved soil with properties equivalent to those of grit soil, with respect to a method for manufacturing the granular improved soil and the granular improved soil.
SOLUTION: The method for manufacturing the granular improved soil 10 first throws construction generation soil 14 and calcined lime 17 from a silo 16 for limestone into a water content adjustment device 12 to adjust the water content of the construction generation soil 14. The water content is adjusted in the range of more than 20% and less than 35%. Next, in a cement addition step 42, the predetermined amount of cement 22 is added from a silo for cement to the construction generation soil 14 adjusted with the water content in step of conveying by a belt conveyor 18. Next, in a mixing step 44, the construction generation soil 14 is crushed and mixed with cement 22. The mixing step 44 is carried out using crushing-mixing device 24 in which the construction generation soil 14 is thrown from the top to a rotated chain 28 and crashed slab 30 to cause it to collide with the chain 28 and the crashed slab 30 at a lower stage in turn to crush it. Simultaneously, it is mixed with cement. Finally, in a curing step 46, the crushed and mixed granular improved soil 34 is conveyed to a curing place by the belt conveyor 32, and cured for 1 to 7 days.

摘要： PROBLEM TO BE SOLVED: To correct the nonconformity of a pumping control system to the nature of ground water. SOLUTION: The levels of water in pumping wells W equipped with motor-driven valves 8 positioned at a few points and water in observation wells located at a few points to correspond to the pumping wells W are measured by means of monometers 9 and the like, and the aperture of each motor-driven valve 8 is automatically controlled in real-time at an accuracy of 0.1% for a 100% of fully opening so that the difference between a set level of water and a measured level of water is dissolved. When the difference (well loss) in level of water between inside and outside of the casing of the pumping well W is large and when the rate of decrease in level of ground water is slow, the amount of water pumped from each well is measured with an electromagnetic flowmeter 12 or the like, and the permeation characteristic of the ground required to estimate the relationship between the flow rate of pumped water and the level of the ground water is automatically calculated through reverse analysis from the measurements of the amount of water pumped from the pumping well W and the level of water in the observation well A during system operation. The present level of the ground water is estimated from the measurement of the amount of water pumped, and the aperture of each motor-driven valve 8 is automatically controlled in real-time at an accuracy of 0.1% for a 100% of fully opening, so that the difference between the present level of the ground water and the set level of the ground water is eliminated.

摘要： PURPOSE:To reduce construction cost by forming the hollow parts for filling a heat insulating material and for heating inside of a steel segment used in an underground tank to store liquefied natural gas or the like, and using a steel plate having excellent low temperature resistant characteristics as an interior surface. CONSTITUTION:A segment is manufactured by nickel steel or the like for a low temperature, and the inside of the building frame is formed as a hollow part 1 for filling a heat insulating material and a hollow part 2 for heating. Next, the hollow part 1 is partitioned by two partition walls 5a and 5a, and is partitioned further by a partition wall 5b, and the hollow part 2 is formed in the shape of being partitioned by partition walls 5a and 5c, and the heat insulating material 3 is filled beforehand in the hollow part 1 at a factory. Next, a continuous air circulating passage is formed in the hollow part 2 in the axis direction of a tunnel when the segment is assembled, and when it is used, hot air is circulated. An interior surface of the segment is designed so as to have strength durable sufficiently even if thermal stress or the like is applied by using a steel plate 4 such as carbon steel for a low temperature. Thereby, labor to install the heat insulating material 3 or a membrance can be eliminated, so that a construction period can be shortened.

摘要： PURPOSE:To construct a large scale LNG underground tank safely at a low cost by a method having the same content as that of a freezing method through utilization of freezing of a ground by means of the cold heat of LNG stored in a small scale LNG underground tank. CONSTITUTION:An underground tunnel in an annular shape in a horizontal direction is excavated in a plurality of rings in the outer periphery of the construction position of a large scale LNG underground tank 2 and a heat insulating material 6 and a membrane 7 are arranged as a lining on the inner surface of a structural body. Airtightness is ensured by using the membrane 7 to build a first stage small scale LNG underground tank 1. LNG is stored for a feed in the small scale LNG underground tank 1. After it is confirmed that the freeze region 8 of a ground occurring owing to a feed is developed to a degree at which no problem arises, the inner ground of the ring is excavated to build a non-freezing type large scale LNG underground tank 2.
