Abstract

PURPOSE:To simplify structure and to propel a lead pipe briefly in the desired direction by connecting a propulsive head, a nose which has an inclined section, to the front nose of a cylindrical propulsive rod having the same diameter and constituting as the lead pipe. CONSTITUTION:A lead pipe 1 in which a propulsive head 3, a nose of which has an inclined section 2, and a cylindrical propulsive rod 4 having the same diameter are connected is turned and propelled, and propelled rectilinearly because the rotational locus of the propulsive head 3 is formed in an approximately columnar shape. When an error is generated between the propulsive direction B and the desired direction A, the revolution of the lead pipe 1 is stopped, and the lead pipe 1 is rotated and adjusted so as to be oppositely face to the erroneous direction B side to the direction A that an inclined face 5 formed to the inclined section 2 must be propelled, and propelled under the state, thus working earth pressure to the inclined face 5, then correcting the direction of the lead pipe 1 to the direction A to be propeiled.

[Detailed Description of the Invention] (Industrial Application Field) In underground piping work, holes necessary for piping are created horizontally underground, and then or at the same time, pipes are inserted. As a pre-process for these construction works, it is first necessary to propel a lead pipe to guide the direction of piping so that accurate piping can be done, but the present invention can propel this lead pipe in the desired direction.

(Prior art) In the conventional propulsion method, when an error occurs in the propulsion direction, the adjustment body is protruded from the inside of the outer propulsion tube to correct the situation using a device that has an adjustment body that can protrude inside the outer propulsion tube. It was meant to change the course by maintaining and promoting it.

(Problem to be Solved by the Invention) However, in the propulsion method as described above, it is necessary to protrude the adjustment body from inside the propulsion outer tube every time an error occurs in the propulsion direction. When the entire slope group of the adjustment body is projected, the propulsion direction of the outer propulsion tube changes greatly, but when a part of the slope is protruded, there is only a small change. It was necessary to adjust the proportion of the adjustment body protruding from the tip of the tube, making the operation very complicated.

(Means for solving the problem) In order to achieve the above purpose, a lead pipe is connected by connecting a propulsion head having an inclined portion at the tip to the front end of a cylindrical propulsion rod with the same diameter as the propulsion head. The lead pipe is rotated and propelled forward, and when an error occurs in the direction during propulsion, the rotation of the lead pipe is stopped, and the inclined surface of the inclined part provided on the propulsion head is rotated in the direction of propulsion. In contrast, we adjusted the rotation of the lead tube so that it faced the wrong direction, and in that state, we continued to propel it until the error was resolved to correct the direction of propulsion, and then we decided to rotate the entire lead tube again while propelling it.

(Function) With the above method, when normally propelling a lead pipe, the propulsion head having an inclined part at the tip rotates together with the lead pipe, so the state of the tonosho acting on the inclined part is as follows.
It remains constant from all directions, allowing for linear propulsion.

On the other hand, if an error occurs in the desired direction of propulsion,
Stop the rotation of the entire lead tube, rotate the entire lead tube so that the inclined surface of the inclined part provided at the tip of the propulsion head faces in the wrong direction with respect to the propulsion direction, and propel it in that state. By doing so, the tonosho acts on the inclined surface, causing the propulsion head to change its course in the opposite direction from the wrong direction, and the course can be corrected to the desired propulsion direction.
