[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for recovering debris generated by the above-mentioned crushing in a device for laying a pipe such as a concrete water pipe or a sewer pipe laid underground or the like while crushing the pipe.

[0002]

2. Description of the Related Art As a device for laying a new pipe without excavating an existing concrete water pipe, sewer pipe, etc., which is piped underground or the like, the present applicant has previously developed the apparatus shown in FIG. I've been. In this apparatus, a crushing unit 1, a new pipe 2, a fragment crushing unit 3, and a propulsion jack 4 are connected in tandem to constitute a re-laying device, and a concrete-made tube 5 disposed underground is replaced with the crushing unit 1. The new pipe 2 is pushed in by the propulsion jack 4 and laid while crushing.

Further, as shown in FIG. 4, the crushed fragments 6 are guided to a fragment crushing section 3, finely crushed by the fragment crushing section 3, collected by a vacuum hose 7 into a storage container 8 such as a drum tube, etc. I try to dump it. FIG.
Reference numeral 9 denotes a reducer in the fragment crushing unit 3, and 10 denotes a screw conveyor blade having a function of feeding and crushing the fragment 6.

[0004]

By the way, when the crushed pieces are stored in the storage container 8, relatively large crushed pieces are collected in the storage container 8, but the finely divided pieces are transferred to the carrier air. They mix and soar into the atmosphere, scattered around. In addition, concrete dust, particularly asbestos-containing dust, is harmful to the human body, and is not a preferable treatment not only for workers but also for environmental hygiene.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a pipe fragment retrieving apparatus for a pipe replacement apparatus capable of performing a preferable treatment in environmental hygiene.

[0006]

In order to achieve the above-mentioned object, a pipe fragment retrieving apparatus of a pipe re-laying apparatus according to the present invention is provided with a crushing section, a new pipe, and a fragment crushing section arranged in parallel. A debris collection unit that sends debris and dust by a vacuum hose from the debris crushing unit,
A storage container to which the vacuum hose is communicated, and a stopper that is provided corresponding to the vacuum hose in the storage container so that the fragments transported by the vacuum hose hit and drop the fragments into the storage container, A cyclone for separating dust and air sent by the hose by connecting a hose led out from the upper part of the storage container, and a valve for dropping the dust separated in the cyclone into the storage container by an opening operation And a unit.

[0007]

The fragments of the existing pipe generated by the crushing section are finely crushed in the crushing section. The crushed pipe fragments and dust are sent to a fragment recovery unit by a vacuum hose. Then, the debris hits the stopper and falls into the storage container, thereby being stored in the storage container. The dust and the air are sent into the cyclone by a hose led out from the upper part of the storage container, and only the air from which the dust is separated by the cyclone is discharged from the cyclone. The dust separated by the cyclone is dropped and stored in the storage container by opening the valve unit.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. Pipe laying equipment is crushing section 11, new pipe 1
2, the fragment crushing unit 13 and the propulsion jack 14 are connected in tandem, and the fragment crushing unit 13 is composed of a reducer 15 and a screw conveyor blade 16 and also accommodates a crushed fragment.
17 are provided. Since these configurations are the same as those of the above-described conventional example, the description thereof is omitted.

The characteristic configuration of this embodiment is as follows.
That is, as shown in FIG. 2, a debris collecting section 19 to which a vacuum hose 18 led out of the storage case 17 is connected is provided. The debris collection unit 19 includes a cyclone 20, and a storage container 21 such as a drum can is provided below the cyclone 20. Specifically, the vacuum hose 18 is connected to one side of an upper lid 22 that is hermetically attached to the storage container 21, and a hose 23 led out from the other side of the upper lid 22 is connected to the cyclone 20 installed on the upper lid 27. ing. The cyclone 20 has an exhaust portion 24 at the upper portion and a valve portion 25 at the lower portion. In the drawing, reference numeral 26 denotes a stopper provided in the upper lid 22 corresponding to the vacuum hose 18, reference numeral 27 denotes a drain valve provided below the storage container 21, and reference numeral 28 denotes a holder for the storage container 21.

[0010] In the above configuration, the tube in the storage case 17,
In other words, crushed pieces such as concrete
Is transported to the upper lid 22 on the storage container 21, and the relatively large crushed pieces hit the stopper 26 and fall into the storage container 21 to be stored. On the other hand, the dust is sent into the cyclone 20 by the hose 23. In the cyclone 20, the dust is swirled, and the dust having a large mass falls on the inner wall of the cyclone 20 due to centrifugal force, and only air containing no dust is discharged from the exhaust unit 24 into the atmosphere. The dust separated in the cyclone 20 is dropped and stored in the storage container 21 by opening the valve unit 25. The stored crushed pieces and dust are discarded for each storage container.

In the pipe fragment recovery apparatus of the pipe replacement apparatus of this embodiment, the crushed pieces of the pipe are directly stored in the storage container 21 such as a drum, and the dust is separated from the air by the cyclone 20. Since it is accommodated, dust can be prevented from being scattered around the pipe body fragment collecting device, no harm is caused to the worker, and it is preferable from the viewpoint of environmental hygiene.

In the above embodiment, the upper lid 22 is used. However, the upper lid 22 may be omitted and the vacuum hose 18 may be directly connected. The storage container 21 is a drum, but may be another container. Further, although the crushing device is constituted by the reducer 15 and the screw conveyor blades 16, the crushing device may be a device other than these members for crushing.

[0013]

[Effects of the Invention] As described above, according to the tube fragment collecting device of the tube replacement device of the present invention, when the tube fragments such as concrete generated at the time of replacing the tube are crushed and collected, the crushed fragments are stored. It is stored by being dropped into this storage container by being hit against a stopper in the container, and the dust generated together with the debris passes through the storage container once with the air when the above-described debris is dropped into the storage container. After being done, it is sent to the cyclone by a hose,
Since the air is separated from the air by the cyclone and further dropped and stored in the storage container by the opening operation of the valve portion, the debris and the dust can be efficiently stored in the same storage container. Therefore, since dust containing concrete or asbestos is not scattered around the work area, it is of course possible to work safely,
It is preferable for environmental hygiene.
