である。DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention is used in the field of burying pipes in the ground using an underground penetrating machine operated by fluid pressure.
(b) 従来の技術
従来、地中貫孔機による配管の埋設方法は第７
図に示す如く、ピツト０１内にて配管０２後端に
地中貫孔機０３前端を当接させ、地中貫孔機０３
を作動させて配管０２を埋設するようにしてい
る。(b) Conventional technology Conventionally, the method of burying pipes using an underground boring machine was the 7th method.
As shown in the figure, the front end of the underground penetrating machine 03 is brought into contact with the rear end of the pipe 02 in the pit 01, and the underground penetrating machine 03
is operated to bury the pipe 02.
ところが前記方法ではピツトの長さＬが配管と
地中貫孔機の各長さの合計により幾分長く必要な
ため、ピツト掘削のために多大な労力及び経費を
必要としていた。 However, in the method described above, the length L of the pit is required to be somewhat longer due to the sum of the lengths of the piping and the underground boring machine, and therefore a great deal of labor and expense is required for excavating the pit.
そこで、前記の如き欠点を解消すべく第６図の
如き埋設方法が考えられた。 Therefore, in order to eliminate the above-mentioned drawbacks, a burying method as shown in FIG. 6 was devised.
すなわち、配管１に地中貫孔機２を挿入し、地
中貫孔機２の後部位置に設けた係合部材１１の当
接面に配管１後端を当接させ、その後全体をピツ
ト４内に降ろし、地中貫孔機２を作動させるよう
にし、これにてピツトの長さｌを短かくすること
ができる。 That is, the underground penetrating machine 2 is inserted into the pipe 1, the rear end of the pipe 1 is brought into contact with the contact surface of the engagement member 11 provided at the rear position of the underground penetrating machine 2, and then the entire pipe is inserted into the pit 4. Then, the underground penetrating machine 2 is operated, thereby making it possible to shorten the length l of the pit.
(c) 発明が解決しようとする問題点
ところで、第６図の如き方法にあつては、配管
