摘要： PROBLEM TO BE SOLVED: To provide an extension method of the existing tunnel capable of economically making widening in the case total extension length is long or even in the case a section is small. SOLUTION: The extension method includes an upper half widening section 20 and a lower half widening section 22, and a widening tunnel 12 including the whole section of the existing tunnel 10 inside thereof is constructed. When the widening tunnel 12 is constructed, a simple protector 24 having an inverted recess section for ensuring the traffic of a vehicle is installed at the inside of a lining layer 14, the excavation of the upper half widening section 20 is carried out before the lower half widening section 22, and a mobile working platform 26 is installed on a bench 28 formed by the preceding excavation in a movable manner along the direction of the axis of the existing tunnel 10. The excavation of the upper half widening section 20 and the fracture removal of side walls 18 of the lining layer 14 are carried out by work from the mobile working platform 26. The excavation of the lower half widening section 22 and the fracture removal of the side walls 18 of the lining layer 14 are carried out by work on roadbeds on the sides of the side walls 18.

摘要： PROBLEM TO BE SOLVED: To efficiently remove heavy metals collected in the vicinity of a cathode by burying the cathode surrounded by an exchangeable material having a high pH buffer function into contaminated soil, impressing DC voltage between the cathode and an anode to adsorb hydroxide group generated on the surface of the cathode electrode on the buffer material and exchanging the buffer material when the potential gradient in the soil becomes nonuniform. SOLUTION: The anode electrode 2 and the cathode electrode 3 are buried in the contaminated soil 1 containing the heavy metals to face each other and a DC power source 8 is connected to the anode electrode 2 and the cathode electrode 3. The material 4 having high pH buffer function selected from kanumatsuchi (soil obtained around Kanume and often used in horticulture city) containing allophane in large quantity, charcoal or the like is exchangeably charged around the cathode electrode 3 housed in a cylindrical bag 5. The heavy metals are collected around the cathode electrode 3 by the electrophoresis phenomenon by the input of the DC electrode source 8 and is concentrated in the material having high pH buffer function after the lapse of certain period. Because the distribution of potential in each part of the soil is changed from linear gradient to curved one with the collection of the heavy metals around the electrode 3, the cylindrical bag 5 is pulled up after the change to newly exchange the material 4. As a result, the heavy metals collected around the cathode are efficiently removed.

摘要： PROBLEM TO BE SOLVED: To prevent useless drilling and reduce a construction period and construction cost by measuring specific resistance of a boring hole, finding a prediction degree of permeability at a position separated from the boring hole, comparing it with a really measured degree of the permeability and judging application of the predicted degree of the permeability. SOLUTION: A grouting agent 12 such as cement grout is pressed in many boring holes 11 drilled in a row at prescribed interval L in ground 10. At the time, the grouting agent 12 is grouted in the ground 10 from the side wall of the boring hole 11 to be widened, and solidified in a continuous state to form a curtain-like impervious film 1. Furthermore, water is prevented from intruding and leaking in the ground 10 through the impervious film 1. The specific resistance of the boring hole 11 is measured in a test section area provided in a previously forming range of the impervious film 1, and a prediction degree of permeability is found at a position separated from the boring hole 11 by the specific resistance. It is compared with a really measured degree of the permeability, the application of the prediction degree of the permeability is judged, and the intervals of the boring holes 11 in the execution area judged as the application are determined on the basis of the prediction degree of the permeability.

摘要： PURPOSE:To improve the workability by providing a drilling machine main body fitted with a constituting bit to a drilling rod via a guide rod operably along a guide cell, and fitting an insertion guide bar near the drilling rod. CONSTITUTION:A drilling machine main body is advanced along a guide cell 3, and a drilling rod 6 is rotated to drill a drilled hole H. An insertion guide bar 11 is fitted to a drilling device so that the tip of the bar 11 precedes the tip of a bit 7 connected to the rod 6 via a guide rod 8. The tip of the bar 11 is located on the drilled hole H and advanced together with the main body via a support bed 10, and the portion adjacent to the drilled hole H is drilled by the rod 6 using the bar 11 as a guide. When the tip of the bar 11 reaches the bottom of the drilled hole H, a hydraulic cylinder is retreated, the rod 6 is advanced, and drilling is performed to the tip position of the bar 11. The bar 11 and the rod 6 are withdrawn from the drilled hole H, the positional relation between the bar 11 and the rod 6 is returned to the original state, then drilling is likewise performed.
