Detailed Description

Example 1

Referring to fig. 1 to 5, a catheter comprises a catheter body 1, wherein one end of the catheter body 1 is provided with a first connecting part 11 with an external spline, the other end of the catheter body is provided with a second connecting part 12 with an internal spline, the first connecting part 11 and the second connecting part 12 of adjacent catheter bodies are in spline connection and are fixed through a plurality of screws 2, a sealing ring 3 is arranged between the first connecting part 11 and the second connecting part 12, wherein the outer diameter L1 of the catheter body 1 is 103-113mm, and the inner diameter L285-95 mm. Preferably, the outer diameter L1 of the pipe body 1 is 108mm, and the inner diameter L2 is 90mm

In an embodiment, the number of the screws 2 is three, the screws are circumferentially arranged, and an included angle between adjacent screws 2 is 120 degrees.

Referring to fig. 3 and 4, the guide pipe 1 is connected with a first target arrow 10 (which is columnar, one end of which is provided with an inclined plane, and the end of the target arrow is provided with an arrow connecting part similar to a second connecting part, and the arrow connecting part is connected with the first connecting part of the pipe body, for example, fixed connection in a spline and screw mode), the guide pipe is continuously connected by using push bench, and the target arrow is aimed by using a laser theodolite, the advancing direction is controlled by transmitting torque to the target arrow 10 through the guide pipe 1, and the deviation rectifying error is avoided, so that the guide pipe 1 avoids the entry of soil, the friction is reduced, the resistance is reduced, and the purpose of penetrating.

The connection mode of each guide pipe 1 adopts an o-shaped rubber sealing ring and 3 inner hexagonal cylindrical bolts (screws) for fixation.

Referring to fig. 5, after the designed path is passed through by the catheter 1, the simple handpiece 40 is used to connect a black tube (a hole-expanding tube, see embodiment 2 specifically), the aperture of the path passed through by the catheter 1 is expanded by extruding the soil, and then the designed tube is connected to the path passed through.

The purpose of the black pipe is to enlarge the hole enlarging caliber of the pushed conduit, the black pipe is connected with the conduit by using a simple machine head, and the pushing route is not settled or deviated in the construction process by the mode.

And each black pipe is connected and fixed by adopting an internal thread sleeve and an external thread joint.

The following description is made of a simple handpiece: the simplified handpiece includes a column portion and a taper portion connected to each other, the end of the taper portion is provided with a conduit connecting portion (similar to the first connecting portion, and connected to the second connecting portion), and the end of the column portion is provided with a reamer connecting portion (similar to the female screw socket in embodiment 2, and connected to the male screw coupling in embodiment 2).

Example 2

Referring to fig. 6, a reaming pipe comprises a reaming pipe body 4, wherein one end of the reaming pipe body 4 is provided with an external thread joint 41, the other end of the reaming pipe body is provided with an internal thread sleeve 42, and adjacent reaming pipe bodies 4 are connected through the external thread joint 41 and the internal thread sleeve 42, wherein the outer diameter L3 of the reaming pipe body 4 is 214 and 224 mm. Preferably, the outer diameter L3 of the reamer body 4 is 219mm.

Example 3

The basic scheme is the same as that of embodiment 1, except that the end of the first connecting part 11 is provided with a columnar mark projection, and the surface of the mark projection is provided with a fluorescent coating. The sign is protruding to the sign effect, does benefit to the installation, prevents to a certain extent simultaneously that first connecting portion from erectting downwards (the pipe is vertical to be placed).

Above only do the preferred embodiment of the present invention, the protection scope of the present invention is not limited to the above embodiment, all belong to the technical scheme of the present invention all belong to the protection scope of the present invention.
