摘要： PROBLEM TO BE SOLVED: To provide an underground radar exploration method, a device and a program therefor of a frequency variable system capable of analyzing a ground structure having frequency dependency. SOLUTION: An electromagnetic wave 38 of which frequency changes at a prescribed pattern, is allowed to enter the underground 1 from a transmitter 18 on the ground surface 2, and a reflected electromagnetic wave 39 from the underground discontinuity surface 3, 4 of the electromagnetic wave 38 is received by a receiver 19 on the ground surface 2 separated at a fixed interval w from the transmitter 18, and a time delay and an amplitude change of the reflected wave 39 to the incident wave 38 are detected relative to each frequency, and the position and the reflectance of the discontinuity surface 3, 4 are calculated relative to each frequency based on the detected time delay and amplitude change. While moving the transmitter 18 and the receiver 19 kept at the fixed interval w along the ground surface 2, a cycle from incidence of the electromagnetic wave 38 to calculation of the position and the reflectance is repeated, to thereby generate a profile 26 classified by the frequency of the underground discontinuity surface 3, 4 based on calculated values of the position and the reflectance of the discontinuity surface at each incident spot.

摘要： PROBLEM TO BE SOLVED: To provide a survey method which allows for reliably understanding geological features of a tunnel face at a shield machine even at a depth below a groundwater table.SOLUTION: An elastic wave generated by an oscillator unit 9 propagates along a surface of a tunnel face 13 and reaches a receiver unit 11. The oscillator unit 9 and the receiver unit 11 are positioned to face a same direction. As such, the elastic wave propagating along the tunnel face 13 and received by the receiver unit 11 contains almost no P-wave component. On the other hand, S-wave (e.g. Sv-wave) component is efficiently received by the receiver unit 11 which is pressed against the tunnel face 13 in the same direction as the oscillator unit 9. In short, the receiver unit 11 is capable of efficiently receiving S-waves. Thus, the receiver unit 11 can receive the elastic wave generated by the oscillator unit 9 without being affected by groundwater.

SOLUTION: The grout solution comprises a calcium-ion-rich first aqueous solution and a second carbonate-ion-rich aqueous solution and deposits calcium carbonate when the both are mixed with each other. The grout work comprises injecting the calcium-ion-rich first aqueous solution and the carbonate-ion-rich second aqueous solution into water stop targets to deposit a calcium carbonate precipitate there. It is also possible to control the deposition of calcium carbonate by using electrophoresis during the deposition.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device for estimating a bleeding channel, which can economically bring about a result equivalent to that of a simple permeability test in a short period of time. SOLUTION: A No.2 boring hole 7, which is excavated in ground 1, is closed with packers 21a, 21b, 21c, 21d, 21e and 21f; and receiving sections 2-a, 2-b, 2-c, 2-d and 2-e are formed. A boring water is fed to a bit 9 from a pump 15 of a boring machine 19, so that a No.1 boring hole 4 and a No.3 boring hole 5 can be bored; and an excavating condition is recorded. Concurrently with that, on the side of the boring hole 7, hydraulic pressure is observed by using pressure gauges 33a, 33b, 33c, 33d and 33e. A position of the bleeding channel between the boring holes 4 and 5 and the boring hole 7 is estimated by comparing the recorded excavating condition with the hydraulic pressure.

摘要： PURPOSE:To sample underground water at great depth using a lightweight device by installing a sampler immediately above an upper packer which blocks a water sampling area, then draining water in the water sampling area, and then sampling true underground water, the sampler having a small packer and a motor pump chamber, etc. CONSTITUTION:A hollow, cylindrical upper packer 1 having a lower packer 2 and a check valve 4 is inserted into a hole of great depth to set a water sampling area. A sampler 4 having a small packer 6, a hydraulic pressure gauge 7, a water quality sensor 8 and a motor pump chamber 11, etc., is provided immediately above the upper packer 1. Water in the water sampling area is pumped using the pump 11A of the sampler and the residual water is discharged from a discharge opening 13 so as to sample only the true underground water. Thus the device is made light and water can be sampled in a natural state without deteriorating an underground water environment.
