回転力を与える方法が多く採られている。) is the most efficient method and device for horizontally propelling and burying pipes while rotating them. This invention relates to a multi-stage rotary pipe burying method in which one or several frames are connected in series to move the pipes forward and bury the pipes in sequence, and the above-mentioned fat body device used directly in this method. Conventionally, as a construction method for propelling and burying small-diameter pipes with a circular outer circumferential cross section underground, a method has been adopted in which earth and sand are cut while the pipes are rotated, and the straightness of the pipe array is maintained. However, when implementing this type of construction method, the method of applying rotational force to the pipe body is generally based on the outer diameter of the pipe body to be buried.
A rotating body with a large inland area is attached to the pipe, the pipe body is tightened by a plurality of screw bolts etc. attached to the rotating body, and rotational force is applied to the pipe body by rotating the rotating body. Many methods have been adopted.

説明する。However, in such conventional technology, when gripping the tube, it is essential that the axis of rotation of the rotating body and the axis of rotation of the tube are perfectly aligned, and it takes a lot of time to make this adjustment. Moreover, depending on the size of the pipe to be buried, a rotating body matching that size is required, and the rotational force varies depending on the quality conditions and the length of the pipe body, so there is a difference between a small diameter short extension and a large diameter long extension. The capabilities of the drive motors and advancement devices for the rotating bodies used naturally differ, and in practice, it is necessary to have several types of large, medium, or small devices depending on the pipe diameter and propulsion length, resulting in significant inefficiency. It is showing. The present invention was developed in view of the deficiencies of the prior art described above, and one embodiment of the present invention is shown in FIGS. 1, 2, and 3 and will be described in detail below.

Further, the frame A is self-propelled by hydraulic jack devices 7, 7 installed inside. Then, the tube body 4 is installed in the frame A, the positions of the rotary tubes 20, 20, 21, and 21 are determined, and the tubes 4 are firmly tightened. The rotary cylinders 20, 20, 21, 21 rotate and transmit rotation to the pipe body 4 through friction with respect to the pipe body 4, and the hydraulic jacks 7, 7 are actuated to sequentially move the cylinder A together with the pipe body 4 into the ground. This is a construction method that moves the building forward in the same direction. When the length of the pipe 4 in the shaft 1 has been advanced, the next pipe 4 is placed in the frame A, tightened, and welded to the end of the existing pipe to form a series of pipes 7...・Suppose. In this way, the rotary cylinders 20, 20 are driven again, and the hydraulic jacks 7, 7 are operated to advance the tube array 4. In addition, if the tube row 4... becomes too long and the rotational force and propulsive force are insufficient, measure the increase or decrease of the force by connecting multiple frames A in series as shown in Figures 1 and 2. It is easy to do. Next, to explain the main body A, firstly, the frame body 6 constituting the key body A is equipped with advance hydraulic jacks 7, 7 at the lower part of both sides, and a rotary cylinder having a relatively long length at the inner lower part. 21, 21 are provided in two lotuses. The rotary cylinders 21, 21
The shafts 23, 23 are parallel to the tube axis and are supported at the front and rear of the frame 6, and a frame support 9 with a hinge structure 10 on one side is provided above the frame 6 so that it can be opened and closed. A part of the frame support 9 is extended 25 to the outside of the frame 6, and a small hydraulic jack 12 is equipped to be supported on the frame 6, while a small hydraulic jack 12 is located in the inner empty space of the frame 6. A driving device B is mounted on the frame support 9. In other words, the drive device B
As mentioned above, the structure is made of a steel tire whose outer periphery is covered with hard rubber or has notches, and two rotary tubes 20, 20 are provided parallel to the axis of the tube body 4. The rotary cylinders 20 and two rivers are rotationally driven by the prime mover 18 via chains (or belts) 19, 19. Further, a support 17 on which the rotary cylinders 20, 20 and the prime mover 18 are loaded is suspended from the frame support 9 by a plurality of hydraulic jacks 16, and is further positioned on the frame 6 of the frame support 9. Locking metal fittings 14, 14 are attached to the pond edge. The locking fittings 14, 14 serve as reaction force receiving members for the jacks 16. In addition, 15 in the figure is the locking metal fitting 14,1.
4, and the lower portions on both sides of the frame 6 are provided to fit the seal members 3, 3. The main body device A is configured as described above. Next, to explain one implementation procedure in detail, first of all, the main body device A is positioned on the rail materials 3, 3 in the shaft 1 in view of the axis of the pipe body 4 in which it is to be buried. It will also be placed at the rear of shaft 1.

しながら処要長の管体4・・・を推進埋設する。Second, the jack 12 is retracted to open the frame support 9, and third, the tubular body 4 of a predetermined length is placed on the rotating tubes 21, 21. Fourth, the jack 12 is extended again to close the frame support 9 and securely fastened with the locking metals 14, 14. Fifth, the jacks 16 are extended and the support body 17 is lowered. At this time, the rotary cylinders 20, 20 are gradually lowered until a predetermined pressure is applied to a part of the outer peripheral surface of the tube 4, and the extension of the jacks 16 is then stopped. In addition, this jack 16.
It is easy to provide a device for maintaining the prescribed pressure by interposing a strong spring mechanism or the like (not shown) located at the axis of the shaft. Sixthly, when the prime mover 18 loaded on the support 17 is driven, the tubes 4 rotate. Seventhly, while rotating the pipe body 4...
, 7 are extended, and the main body device A is advanced toward the buried ground side. Repeat the above operation and add pipes 4 in sequence.
At the same time, the pipe body 4 of the processing section length is propelled and buried.

This is handled by the friction caused by the rear area of the rotary cylinder 20 and the outer circumferential surface of the tube or by the pressure force. On the other hand, in order to assist the advancement of the key body A, spacers 8, 8 as reaction force supporting members may be employed on the parallax lines of the jacks 7, 7, if necessary.

管体を回転させながら推進させることが可能となった。The present invention is configured as described above, that is, it directly applies rotational force and propulsion force to the tube body 4, and when the rotational force and propulsion force are insufficient with only one main body A, multiple bodies A...・As it is very easy to use them in series, there is no need to have different types of mechanical devices with different capacities such as large, medium, and small as in the past. It became possible to propel the tube while rotating it in the most efficient manner.

。Furthermore, the usefulness of the present invention is that the tubular body 4 is reliably clamped by the rotary cylinders 20..., 21... of a number of numbers (for example, 4 lotus), so unlike the prior art, the rotational force is directly transmitted. There is no need for any complicated adjustment operations required to match the rotation axes of the moving device and the tube body, and on the other hand, the distance between the two upper rotary tubes 20, 20 and the lower two rotary tubes 21, 21 can be adjusted freely. Therefore, there is no need to install special equipment as an accessory for pipes of different diameters, and the frame support 9 supporting the drive device B is completely separated from the frame 6. Since the pipe body 4 has a structure that can be removed easily and easily, the pipe body 4 can be easily inserted into the frame body 6 from above regardless of the position of the frame body 6 in the shaft 1. Unlike the method described above, there is no inconvenient operating method such as inserting a rotating device for the tube from the rear of the tube, making it an extremely efficient method. In addition, conventionally, this type of construction method required a large shaft due to the adoption of relatively long ready-made pipes, and was inconvenient for narrow sites, but with the present invention, Since not only long pipes but also short pipes can be used freely and reliably, the system is more efficient, workable, and economical than ever before. It should be noted that the present invention can be freely designed and constructed in addition to the above-mentioned first embodiment without departing from the inventive idea according to the patent law.
