Pipe burying method

Abstract

The invention provides a pipe burying method by which a diameter of a pilot hole can be efficiently and reliably enlarged depending on various types of soil and a burying operation of a buried pipe is made stable. The method involves preparing various types of platy members, selecting a platy member suitable for a soil type from among the various types of platy members on the basis of a soil type search of a burying place, and attaching the selected platy member to a reamer main body, thereby forming a reamer suitable for the soil type. The method further involves annexing this reamer at a front end of a rod in a pilot hole, and pulling out this rod from the pilot hole while rotating the reamer together with the rotation of the rod, thereby burying a buried pipe to be connected to the reamer in the earth.

1 . A pipe burying method for burying a buried pipe in the earth by using a reamer having a reamer main body that is approximately cone-shaped, of which diameter is contracted toward the side into which it is retracted, and a platy member to be annexed to the outer surface of this reamer main body and to form a drilling part, the method comprising the steps of: 
 preparing various types of platy members;    selecting a platy member suitable for a soil type from among the various types of platy members on the basis of a soil type search of a burying place;    attaching the selected platy member to a reamer main body to form a reamer suitable for the soil type;    annexing this reamer at a front end of a rod in a pilot hole in the earth;    pulling out this rod from the pilot hole while rotating the reamer together with the rotation of the rod; and    burying a buried pipe to be connected to the reamer in the earth.    
   
   
       2 . A pipe burying method for burying a buried pipe in the earth by using a reamer, the method comprising the steps of: 
 preparing various types of reamers;    selecting a reamer suitable for a soil type from among the various types of reamers on the basis of a soil type search of a burying place;    annexing the selected reamer at a front end of a rod in a pilot hole in the earth;    pulling out this rod from the pilot hole while rotating the reamer together with the rotation of the rod; and    burying a buried pipe to be connected to the reamer in the earth.    
   
   
       3 . The pipe burying method according to  claim 2 , wherein 
 the reamer has a reamer main body that is approximately cone-shaped, of which diameter is contracted toward the side into which it is retracted, and a platy member to be annexed to the outer surface of this reamer main body and to form a drilling part, and various types of reamers are formed by changing this platy member.
