    • PROBLEM TO BE SOLVED: To provide a method for recovering contaminants at its the primary location for recovering effectively the contaminants in soil which can be easily applied to the contaminated soil lying under an existing structure. SOLUTION: Pipes 4 and 5 to be laid by the bending excavation from the ground are set almost horizontally in soil 1 contaminated with harmful contaminants, and the contaminants in the soil are separated in the original site by using the pipes 4 and 5 and the like and recovered onto the ground. As a means for separating the contaminants, a plurality of power-applicable pipes 4 and 5 to be laid by the bending excavation from the ground are set in parallel almost horizontally at intervals L in the ground 1 contaminated with harmful contaminants, and one of the pipes 4 and 5 is used as a water collecting pipe 4 with a number of water collecting holes, while the other pipe is used as a power applicable pipe 5 in the constitution of a pair of pipes or pairs of pipes. Direct current supplied from a direct current power source device 6 is applied to respective water collecting pipe or pipes 4 and the power applicable pipe or pipes 5 forming a pair or pairs, and contaminants collected together with clearance water from the contaminated soil 1 are collected into the water collecting pipe or pipes 4 by the electrical separation and recovered onto the ground. Also the contaminants can be recovered in the gaseous state.

    • PURPOSE:To measure the direction and inclination of boring continuously in boring operation by fixing a direction/inclination measuring device which is equipped with a compass and a television camera for photographing it to the front part in a propulsion tube, and connecting the television camera to a display recording device on the ground. CONSTITUTION:A monitor television 20 is connected to the television camera 2 through a control part 19. Further, a cross hair line system 21 is connected to the monitor television 20 and an arithmetic processor 22, which is corrected to the recording device 23 which records the direction, inclination, and angle of rotation and a monitor television 24 for track display; an image of the compass isplayed on the monitor television 20 is read to find the direction angle, inclination angle, and rotation angle.
    • 目的:通过将装有罗盘的方向/倾斜测量装置和摄像机的电视摄像机固定在推进管的前部,测量镗孔连续钻孔的方向和倾角,并将电视摄像机连接到 地面上的显示记录装置。 显示器电视机20通过控制部分19连接到电视摄像机2.此外,十字线系统21连接到监视电视机20和运算处理器22,其被记录到记录装置23上 旋转的方向,倾斜度和角度,以及用于轨道显示的监视器电视机24。 读取显示器电视机20上显示的罗盘的图像以找到方向角度,倾斜角度和旋转角度。
