摘要： PURPOSE:To provide the titled liquid capable of preventing the loss of water in the excavation work such as slurry shield and the construction of a continuous underground wall using a low-cost waste material, by adding a flaky mineral as an agent for preventing the loss of water to slurry. CONSTITUTION:The objective wall-stabilizing liquid is prepared by adding a flaky mineral (preferably mica sludge having a diameter of 50-2,000mu and a thickness of 0.1-10mu) to bentonite slurry, etc. The mica sludge is a slurry consisting of water and a slurry produced by the purification of raw mica to obtain various goods, e.g. fine mica flakes produced by the preparation process of collected mica.

摘要： PURPOSE:A solidifying agent of cement that contains cement and an inoganic ammonium salt, thus being capable of rapidly solidifying even organic soil containing humus in a short time. CONSTITUTION:An inorganic ammonium salt as ammonium sulfate is added to a solidifying agent of cement. The addition of the inorganic ammonium salt to cement accelerates the hydration of cement even when the soil contains humus that inhibits the hydration reaction. Futher, the formation of ettringite is observed, which is thought to be a factor to develop the high strength.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device for accurately positioning an impervious sheet-restoring shaft bored in a waste disposal plant. SOLUTION: Metallic bars F are vertically driven up to a prescribed depth 43 from the surface of waste 6 in plural positions in a division H including a water leakage position 11 on an impervious sheet 10 arranged on the bottom surface of the waste disposal plant 2, and a water leakage signal according to a distance to the lower end of the metallic bars F from the water leakage position 11 is detected. Horizontal coordinates of the water leakage position 11 are estimated on the basis of the water leakage signals detected in the plural positions, and the shaft 7 for restoring the impervious sheet 10 is positioned on the estimated horizontal coordinates. Desirably, when electrodes Bi and Cj are arranged on the gropund side of the impervious sheet 10, the metallic bars F are driven at an interval narrower than a required diameter ϕof the restoring shaft 7 in the division H, the upper end of the metallic bars F and the electrodes Bi and Cj are connected to a power source 16, electric currents IBi and ICj flowing to the electrodes Bi and Cj are detected as the water leakage signal, and the horizontal coordinates of the water leakage position 11 are estimated on the basis of the electric currents IBi and ICj detected in the plural positions.

摘要： PROBLEM TO BE SOLVED: To provide a depth measuring system which measures the underwater ground shape accurately in real time. SOLUTION: A stationary station 1 is equipped with a stationary GPS receiver 4 connected with a stationary GPS antenna 3 in known position and a transferring GPS signal transmitter/receiver 5 connected with a stationary GPS receiver 4. A measuring ship 2 is equipped on board with a mobile GPS antenna 8 and automatic depth sounder 11 with positions aligned to the perpendicular direction, a mobile GPS receiver 9 connected with the mobile GPS antennas 8, a transferring GPS signal receiver/transmitter 10 connected with the mobile GPS receiver 9, a data transmitter/receiver 14 connected with the automatic depth sounder 11 and mobile GPS receiver 9, and a synchronizing device 12 whereby the position measuring of the mobile antenna 8 performed by the GPS relative position measuring method through cooperative use of the stationary GPS antenna 3 and mobile antenna 8 is synchronized with the depth measuring using the automatic depth sounder 11. A CAD personal computer 7 is coupled directly or indirectly with the data transmitter/receiver 14, and the position of the mobile antenna 8 and the depth in this position acquired in synchronized measurement are plotted on the depth chart.

摘要： PURPOSE:To avoid the deformation of an underground concrete structure for making its construction easier by a method in which a releasing layer is provided on the surfaces of steel materials to be removed by pulling are buried in the concrete wall, and tension steel members are inserted into the holes formed in the concrete wall by removing the steel materials. CONSTITUTION:A given depth of pits are excavated in the ground, steel materials 1 whose surfaces are provided with releasing layers, along with iron bar cages, are erected into the pits. Then, concrete B is placed into the pits and hardened, and then the steel materials 1 are pulled out. A boring mechanism 3, as needed, is inserted into the holes formed by pulling out the steel materials 1 until it reaches below the concrete wall and drilled, and tension steel members 4 are inserted into the holes and grout is injected.

摘要： PURPOSE:To accomplish the early stabilization of the soil of high water content by promoting hydration of cement with addition of water soluble ammonia compound in the solidification and stabilization of the high water content soil mixed with ordinary poltland cement. CONSTITUTION:In early stabilization of the soil of high water content including excavated mud used for excavating continuous underground walls, the soil is mixed with ordinary poltland cement and added by ammonia compound generating ammonia ion dissolved in water. For the ammonia compound, preferably used is ammonia sulfate most inexpensive and easy to handle and obtain. The material added is preferably fixed at a rate of 2-8% by weight in terms of the weight of the cement. This promotes the hydration of the cement while producing an ettringite substance thereby assuring early solidification and stabilization of the high water content soil.
