Filed: 1994-10-18
Abstract: PURPOSE: To increase the strength of a ground by a method wherein water is infected into a sandy ground, an infiltrating flow is generated, water, in which grains smaller than sand grains in the sandy ground are mixed, is injected, water injection is stopped and water is absorbed from the sandy ground. CONSTITUTION: When a pipe member 20 is inserted into a sandy ground 10 and water is injected through holes 14 from a water supply source 12, infiltrating flows are generated in the ground 10, excess void water pressure is generated in a water injection region, and boiling or fluidization is generated. Water, in which the grains of cement, bentonite, etc., smaller than the sand grains of the ground 10 are mixed, is injected and dispersed into the water injection region of the ground 10 through the holes 14. When the supply of water is stopped and negative pressure is applied to holes 18 from a negative pressure source 16, water in the water injection region is sucked to the negative pressure source 16 while grains are left among sand grains.  The boiling of the water injection region is stopped, and the spaces of the grains and sand grains are narrowed at peripheral soil pressure and brought to a consolidated state. Accordingly, ground density is increased, and strength can be improved.

Filed: 1985-12-10
Abstract: PURPOSE:To separate the input and output of reflective optical amplifiers without using a circulator and obtain a high saturated output by providing a plurality of the reflective optical amplifiers, a directional coupler and a phase regulator. CONSTITUTION:An input light 30 is inputted from an input terminal 1 and divided into two by a half mirror 2 and the divided lights are inputted to two reflective optical amplifiers 5 and 6 with the identical characteristics. The lights inputted to and amplified by the reflective amplifiers 5 and 6 travel along the light paths to the opposite direction and synthesized by the half mirror 2 and the resultant light is outputted from an output terminal 9. If the respective phases of the lights outputted from the respective reflective optical amplifiers 5 and 6 are regulated so as to be identical at the output terminal 9 when the lights are inputted to the half mirror 2, the output summation of the reflective optical amplifiers 5 and 6 is obtained at the output terminal 9 of the half mirror 2 only and the amplified output is not returned to the input terminal 1 by the interference effect of the lights. As two amplifiers are employed like this, a saturated output can be doubled and the input light and the output light can be separated without using a circulator.
