摘要： PROBLEM TO BE SOLVED: To secure dry work and prevent floating of an underground structure by creating a lower slightly permeable bottom base at a particular lower position from the upper slightly permeable bottom base created at the deeper position from the underground structure. SOLUTION: A grid-shaped beam 2c for connecting inner and outer impermeable walls 2a, 2b in the ground consisting of sand gravel layer with a high permeability and a shallow groundwater level is built, thereafter, the impermeable walls 2a, 2b are built. Then, an upper slightly permeable bottom base 1a is built at a position deeper than the underground structure B, a lower slightly permeable bottom base 1b having a plan shape larger than that of the upper slightly permeable bottom base 1a is creased at a position lower by layer thickness of a drain layer from the upper slightly permeable bottom base 1a. Then, for each closed portion surrounded by the inner and outer impermeable walls 2a, 2b and grid-shaped beam 2c, the groundwater level is lowered by a water pumping-up well 4 provided to a depth reaching a water drain layer A", thereafter, the ground surrounded by the upper slightly permeable bottom base 1a and the inner impermeable wall 2a is excavated and the underground structure B is constructed.

摘要：【課題】汚染土壌の浄化効率を向上させる。【解決手段】帯水層12が温水Hとなると、井戸120の第一井戸鋼管240で帯水層12から揚水した汚染物質を含む温水Hを浄化装置112で浄化する。そして、浄化装置112において温水Hで浄化することで、空気を送り込んで揮発性汚染物質を揮発させて水質改善する場合、温度が高い方が揮発しやすいため浄化効率が向上する。或いは、浄化剤を添加し反応させて水質改善する場合も、温度が高い方が、反応速度高くなるため浄化効率が向上する。つまり、温水Hで浄化することで浄化効率が向上し浄化が促進する。【選択図】図1
摘要翻译：要解决的问题：提高污染土壤净化效率。解决方案：当含水层12中的水变为温水H时，净化装置112净化包括从含水层12抽出的污染物的第一井钢的温水H 用于井的管道240.当通过进入空气来蒸发挥发性污染物以改善水质时，如果污染土壤在净化装置112中用温水H净化，则污染土壤的净化效率得到改善，因为挥发性污染物在较高温度下更容易蒸发。此外，即使添加纯化剂并进行反应以提高水质，污染土壤的净化效率也得到改善，因为温度越高，反应速度越快。换句话说，当用温水H净化污染的土壤时，提高净化效率，加速净化。

摘要： PROBLEM TO BE SOLVED: To control a ground-water level in a wide area. SOLUTION: Water-level indicators which are equipped with a communication function are installed respectively in ground-water observation wells 1 which are arranged in observation points in a region, to be controlled, in which a ground water current is clarified in advance. A person who intends to pump up ground water notifes a public office as a main control organization. In water pumping wells 2 it is required to install flowmeters which are equipped with a communication function and flow-rate controllers. The respective devices perform measuring operations at sampling intervals which are instructed from the computer of a control center 3, and they hold measured data, and they transmit the data to the control center 3 according to a request. The measured data are recorded and judged in a centralized manner in real time through the public line of NTT or the like. When a reference water level is lowered for a definite time or more, or when it is anticipated that the reference water level is lowered, proper water-pumping control measures can be taken automatically.

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.
