Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a method for replacing old pipes and an operating machine used for the replacement.

(Prior Art) Conventionally, when replacing old sewer pipes with Huyum pipes, the entire buried road was dug up and a new Huyum pipe was buried. However, excavating or burying the entire buried portion of the road requires too much time and money, and also obstructs traffic for a long time, causing traffic congestion.

As a construction method to solve these problems, as shown in Figure 5, the road is partially excavated, one side is used as a starting shaft, the other side is used as a reaching shaft, a front jack is installed on the reaching shaft side, and the existing pipe is passed through. A propulsion device called an impact molding is connected to the wire rope, a cracking head is attached to the tip of the impact molding, and a new humid pipe is connected, and a cranking head is connected to the compressor from the rear. A construction method is used in which old ceramic pipes are crushed and propelled while being towed and buried using front jacks, but with this method, the crushed old pipes become industrial waste and must be removed from the site. I left it there even though I shouldn't have done it.
Furthermore, when the next pipe is replaced, crushed materials will accumulate, making it impossible to insert a new pipe. Moreover, it has the disadvantage that it cannot be used for anything other than ceramic pipes.

(Objectives of the Invention and Means for Solving the Problems) Therefore, an object of the present invention is to simultaneously remove the conduit used for extraction and bury a new sewer pipe without crushing the existing sewer pipe.

Therefore, we connected a conduit with an inner diameter larger than the outer diameter of the existing hume pipe or ceramic pipe to the tip of the propulsion machine, attached a metal crown to the tip of this conduit, propelled it while rotating, pushed it to the reaching shaft, and then propelled it. Connect the entraining machine to the front of the entraining machine, push out the conduit and existing old pipes at the front of the entraining machine, connect a new hump pipe to the rear of the entraining machine, use the propulsion machine to push the operating machine, and move the front installed in the reaching shaft. The old pipes were replaced with new pipes using a method of pulling them together with jacks.

The operating machine used in this case has a contact surface on the front for propelling the existing pipe and the conduit inserted into the outer circumference of the existing pipe toward the reaching shaft side, and a direction correction device connected to a hydraulic hose on the rear. A hydraulic jack is provided for this purpose, and a mounting section for attaching the new fume pipe is provided in the prior art, and at the same time, the conduit and the existing pipe are pushed and the new fume pipe is pulled.

(Examples and effects) Embodiments of the present invention will be described with reference to the drawings.

First, dig the starting shaft X, then at appropriate intervals (for example, 10?
) Dig the shaft Y that you will reach first.

As shown in Figure 1, a propulsion machine A connected to a power source (not shown in the drawing) is installed in a starting shaft A metal crown 3 is attached to the tip and inserted into the outer periphery of the existing pipe C, and the conduit B is rotated by the propulsion device A toward the reaching shaft Y while being successively added and propelled. Then, the metal crown 3 attached to the tip of the conduit B cuts the attached branch pipe G on the way.

When the propulsion of conduit B is completed, next, the navigation device 1 is installed in front of the propulsion device A.

As shown in the fourth diagram, this operating aircraft 1 reaches the vertical shaft Y in front.
It is connected to a Gebinde steel rod P that is interlocked from a front jack E installed at the front, and has a plurality of hydraulic jacks 1a at the rear, which are interlocked with a hydraulic hose 1b. During propulsion, the operator operates the hydraulic jack 1a while looking at the measuring instrument on the power source side, so that the direction of the operating aircraft 1 can be corrected so that it is propelled in the correct direction. A new humid pipe is connected to the rear of this operating aircraft 1, and the rear end of the previously propelled pipe B and the existing pipe C are brought into contact with the front contact surface 2,
Set this so that it can be pushed out.

After the set is completed, when the front jack L prepared in the arrival shaft Y and the propulsion machine A installed in the departure shaft X are operated simultaneously, the front jack E pulls the operating machine 1, and the propulsion machine A This is a construction method in which the conduit B and the existing pipe C at the front of the operating aircraft 1 are pushed out, and the new humid pipe installed at the rear is pulled and installed.

The shape of the tip of the operating device 1 may be cone-shaped, and is not limited as long as it can push the conduit B and the existing pipe C at the same time.

As shown in Figure 3, the conduit B and the existing pipe C (old humid pipe) pushed out into the reaching shaft Y come out unbroken, so they can be carried out by directly hanging wires.

(Effect) A metal crown, which is a rotating blade, is attached to the tip of a conduit with a larger inner diameter than the existing pipe using a propulsion machine from the starting shaft.
Since it is propelled, the attached branch pipes along the way can be cut and the conduits can be propelled one after another to the reaching shaft for installation.

After the conduit is installed, a moving machine equipped with a hydraulic jack attached to the tip of the propulsion machine can simultaneously push out the existing pipe and conduit and tow and install the new humid pipe.

Moreover, since the old existing pipes are pushed out to the reaching shaft without breaking them, waste can be easily disposed of without leaving it in place.

Furthermore, even when replacing old pipes several years from now, the work can be carried out smoothly since old pipes will not accumulate.

Further, although the conventional technology cannot be used for aged pipes unless they are fragile ceramic pipes, the present invention can treat both ceramic pipes and Huyum pipes.

Since the operating aircraft is equipped with multiple hydraulic jacks, the direction can be corrected and the aircraft can be propelled accurately.
