Abstract

PROBLEM TO BE SOLVED: To dispense with sand loading work in ground embedding so as to accomplish reduction in a construction term and in construction costs by forming a cable protection tube protecting a cable and the like buried in the ground into a shape whose cross section is formed into a triangular substantially in the outline and formed into a circle in the internal shape. SOLUTION: In a tube 1 buried in the ground so as to be used as a cable protection tube, its cross section crossing a tube axis orthogonally is formed into a substantially equilateral triangle, whose vertexes 11 are notched approximately parallelly to the respective opposed sides, in the outline and is formed into a circle in the internal shape. In usage of the tube 1, for example, nine tubes 1 are arranged in 3 lines and in three levels while their tube axes are directed in the same direction and the longitudinal one side of one tube 1 is brought into contact with that of another adjacent tube 1. That is, in the first level, the tubes 1 on both sides are arranged downward with their vertexes 11 set on the lower side while the tube 1 in the center is arranged upward with its vertex 1 set on the upper side, and in the second level, the tubes 1 on both sides are arranged upward while the tube 1 in the center is arranged downward. In the third level, the tubes 1 are arranged in the same way as the tubes 1 in the first level. These tubes 1 are temporarily fixed by means of an annealing wire and the like so as to be assembled together, and then, embedded in the ground for piping, and afterward, back filling is carried out for installation.
