摘要： PURPOSE:To construct an aeration tank or ventilation hole in an extremely deep layer by utilizing a RC precast pipe. CONSTITUTION:A jack down device 4 is set in the ground position of the upper part of an excavated hole 3, and a hanging material 7 mounted on a receiving frame 6 for setting a top RC precast pipe 1 whose top end is sealed is supported by the jack down device 4. The following RC precast pipe 1 is vertically superposed on the RC precast pipe 1, and water is injected into the hollow part of the RC precast pipe 1 by the length of connecting the RC precast pipe 1 by the operation of the jack down device 4 supporting the hanging material 7, and the RC precast pipe 1 is settled in the excavated hole 3 while taking the balance with buoyancy. The shaft structure of the RC precast pipe 1 reaches a determined depth and is completed, a back-filling material 10 is constructed in the clearance between the excavated hole 3 and the shaft structure. The RC precast pipe is effectively utilized to contribute to the rational and economic construction of a shaft. It also contributes to the shortening of the constructing period because of the easy construction. The completed shaft is effectively utilized for various purposes such as an aeration tank in an extremely deep layer.

摘要： PROBLEM TO BE SOLVED: To prevent floating of an underground structure by arranging a drain well in the part surrounded by inside/outside impermeable walls of self-standing type double impermeable walls and lattice-like beams, and constructing the underground structure by excavating th ground stranded by a water impermeable bottom plate and the inside inpermeable wall. SOLUTION: Self-standing type double impermeable walls 2 using the bottom part as a drain layer 3 are constructed by connecting an inside impermeable wall 2a and an outside impermeable wall 2b arranged on a water impermeable bottom plate 1 in a radial shape by lattice-like beams 2c. Next, an underground structure B is constructed by excavating the ground A' surrounded by the water impermeable bottom plate 1 and the inside impermeable wall 2a after sufficiently lowering underground water level in an execution work area by operating a pumping well. In this case, since the self-standing type double impermeable walls 2 are high in rigidity by being constituted of the impermeable walls 2a, 2b and the lattice-like beams 2c, the underground structure B can be constructed at an interval from the inside impermeable wall 2a to use the interval 6 as a dry area. Therefore, impermeable performance can be excellently secured over a long period at earthquake time to prevent floating of the underground structure by water pressure and buoyancy of underground water after execution work.

摘要： PURPOSE:To obtain a triaxial piping test device and the test method performing the permeability (piping characteristics or boiling characteristics) test of actual ground soil under triaxial stress state equal to the actual ground by collecting undisturbed sample not disturbed by the actual ground. CONSTITUTION:A test piece 4 is sealed by covering with rubber film over the outer surface of a sample piece formed with an undisturbed sample. On both ends of the axis direction of the test piece 4, pushing pressure equivalent to the original position ground is added, and on the side surface, pressure for binding the hoop strain is added. In between the part for adding the pushing pressure to the test piece 4 and the end of the test piece 4, a spacer 14 which transmits the pushing pressure but does not bind boiling is put. The water passing to the axis direction of the test piece 4 needs to be degased water or water given a back pressure for raising the degree of saturation to near 100% and a large water head difference H necessary for the piping test is given to between the supply pressure and the exhaust pressure.

摘要： PURPOSE:To regulate running water discharged to the outside of a golf links to the effluent standard value or below for agricultural chemicals by removing the agricultural chemicals which are contained in drainage of the golf links and run off therefrom by adsorption with activated carbon or the like. CONSTITUTION:A manhole is provided in golf links and agricultural chemicals are absorbed and removed from drainage collected in this manhole. In this method, a catchment storage tank of the inside of the manhole 1 is partitioned into a running water passage continued in the vertical direction. An adsorbent layer 7 such as activated carbon is provided to the upward passage. Drainage collected from the golf links is supplied to the downward passage 4 and passage through the adsorbent layer 7 as the upward flow. In the meantime, agricultural chemicals incorporated in this drainage are adsorbed and removed. The drainage is run off from an effluent pipe 9. Further drainage (seepage water) is collected through a catchment pipe 5 from the inside of the golf links. While the same is passed through the adsorbent layer 7 as the upward flow directed to the upper layer from the lower layer, the agricultural chemicals incorporated in the drainage (seepage water) collected via a drainage pipe 5 are adsorbed and removed. Impurities such as sand and refuse incorporated in drainage collected in the manhole 1 are previously removed and do not reach the adsorbent layer 7. Clogging is made difficult to be caused. Since drainage is passed through the adsorbent layer 7 as the upward flow, water is uniformly passed through the absorbent layer 7 and moreover a water channel is make difficult to be formed.

摘要： PROBLEM TO BE SOLVED: To provide a harmlessness treating method of soil on the ground contaminated with dioxin or PCB, or dioxin attached to sedimented earth in the sea, rivers or lakes.
SOLUTION: Soil to be treated 1 is charged into a treatment furnace 13 through charging ports 2-7 of exhaust structure for discharging contained air. The inside of the furnace 13 is heated up to 500°C or higher in a reducing atmosphere kept at a negative pressure to the extent of preventing leakage of gas to the outside of the furnace. The soil 1 to be treated is retained for 10 minutes or longer in the furnace 13 for thermal decomposition, then the cleaned earth 11 is discharged from discharge ports 8-10 of exhaust structure. The above processes are continuously conducted.
