Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for burying a relatively small-diameter underground pipe such as a sewer pipe, a communication pipe, or the like by propelling the ground by propelling the ground without excavating the pipe. The present invention relates to a temporary pipe device to be used.

[0002]

2. Description of the Related Art In laying underground buried pipes by a non-drilling pipe burying method, a plurality of discharge pipes are generally supplied one after another from behind a digging device. It takes a great deal of labor and time to connect the discharge pipes that occur in the area. This requires not only the work of connecting the discharge pipes, but also the work of adding cables and hoses connected to the digging device, and passing the cables through the discharge pipes that were also added. It is due to.

[0003] Therefore, there has been a demand for the development of an efficient and economical non-drilling pipe burying method which can replace the conventional non-drilling pipe burying method.

[0004] As a recent technology, a method has been developed in which a temporary pipe device having a digging device disposed at the tip is propelled and installed in a first step, and then a main pipe is propelled and installed in a second step. ing. As this method, (a) a temporary pipe device in which cables such as hydraulic oil hoses and a discharge pipe are previously piped inside the pilot pipe and connection portions are provided at both end faces of the pilot pipe. What to use, or
(B) cutting a part of the circumference of the discharge pipe to form an opening;
After connecting the cables housed in the discharge pipe through this opening, the opening is covered with a structure that reduces the strength of the connection of the discharge pipe and the rigidity of the entire discharge pipe caused by the opening. Examples using a temporary pipe device that supplements the above with reinforcement processing have been published.

[0005]

However, in the non-drilling pipe burying method using the temporary pipe device (a) shown in the conventional example, the same number of connecting portions of cables as the number of temporary pipe devices are required. Therefore, as cables, for example, for hydraulic system piping, there are disadvantages such as an increase in the number of expensive connecting couplers and an increase in hydraulic pressure loss. Also,
In many cases, the pipe connection points are fixed to the face panels at both ends of the temporary pipe device so that multiple pipes can be connected collectively.
In this case, high-precision processing in which the fixed position between the pipe connection parts is relatively strictly determined is required, and a significant increase in system cost cannot be avoided.

[0006] Also, in the method of burying an open-cut pipe using the temporary pipe apparatus of the above (b), the strength of the exhaust pipe lost is remarkably reduced, and a great deal of cost is required for its reinforcement. In the same way as above, a significant increase in system cost cannot be avoided. Therefore, the cost reduction in the shortening of the construction period is offset by the increase in the system cost, and it is not expected that the intended effect is sufficiently achieved, that is, the shortening of the construction period and the reduction of the cost are simultaneously achieved.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a non-drilling pipe burying method and a temporary pipe apparatus capable of simultaneously reducing the construction period and the cost.

[0008]

According to a first aspect of the present invention, a plurality of temporary pipe devices are sequentially supplied behind a digging device for digging and propelling underground.
After burying the temporary pipe device in the ground, this is a non-drilling pipe burial method in which the main pipe is buried by pushing the main pipe from behind the temporary pipe device. By storing the storage passage in the storage passage provided in the pipe device and enabling the storage passage to be opened and closed over the entire longitudinal direction, the storage passage of the temporary pipe device supplied one after another,
A non-drilling pipe burying method characterized by storing the cables is provided.

According to a second aspect of the present invention, in the first aspect of the invention, when connecting the temporary pipe device at the first position to be buried earlier and the temporary pipe device at the next position to be buried next, first, After connecting the discharge pipe of the temporary pipe device at the rear position to the discharge pipe of the temporary pipe device at the front position, and storing the cables in the storage passage of the temporary pipe device at the rear position, the connection of the temporary pipe device at the previous position is recovered. And a connecting jig of the temporary pipe device at the rear position is connected by a pin.

According to a third aspect of the present invention, in the first or the second aspect of the present invention, after all the temporary pipe devices necessary for embedding the main pipe are buried, one of the front end side and the rear end side is used. A method for burying a non-drilling pipe characterized by extracting cables in a storage passage is provided.

According to a fourth aspect of the present invention, there is provided a temporary pipe apparatus which is sequentially supplied to the back of a digging apparatus for digging and propelling underground and forms a pipeline in a stage before burying a main pipe. A storage passage for storing cables connected to the digging device, the storage passage being configured to be openable and closable over the entire length thereof so that cables extending from the excavation device side can be stored as they are. Is provided.

According to a fifth aspect of the present invention, in the fourth aspect of the present invention, the storage passage is located at a position above the discharge pipe for discharging earth and sand excavated by the excavation device backward, and is located within the excavation range of the excavation device. The provision of a temporary pipe device characterized by being provided in a temporary pipe device.

According to a sixth aspect of the present invention, in the fifth aspect of the present invention, the side wall spacer and the lower surface spacer are provided on the left and right side surfaces and the lower surface side of the discharge pipe within the excavation range of the excavating device, respectively. The temporary pipe device is characterized in that the cross section is formed in a cross shape with the discharge pipe as the center.

According to a seventh aspect of the present invention, in the fourth, fifth or sixth aspect of the present invention, the storage passage itself is configured to be watertight, and is connected to other storage passages in a watertight manner. The provision of a temporary tube device characterized in that:

[0015] Claim 1 configured as described above.
In the described invention, after the temporary pipe device is buried, the main pipe is pushed in from the rear of the temporary pipe device so as to be buried, so that when burying the main pipe, the main pipe is pushed with a relatively low thrust. And only the main pipe needs to be added and connected. Therefore, high-speed connection by high-speed propulsion of the main pipe is possible.

When the temporary pipe device is buried, the storage passage can be opened and closed, so that the cables extending from the previously buried temporary pipe device are stored as they are in the storage passage of the next temporary pipe device. can do. That is, when adding the temporary pipe device, it is not necessary to add the cables, and at the same time, it is possible to use long cables. Therefore, it is possible to simultaneously shorten the construction period and reduce the cost.

Further, when a hydraulic hose, for example, is used as the cables, the number of couplers to be connected is reduced, so that the cost can be reduced and, for example, the hydraulic actuator mounted on the digging device can be used. The pressure loss of the working oil supplied to the (hydraulic motor) can also be reduced. That is, the mechanical efficiency can be improved.

According to the second aspect of the present invention, since the storage passage is a separate passage from the discharge pipe, the cables can be easily stored in the storage passage and the connecting jig in the discharge pipe can be used. By connecting with a pin, the temporary pipe device can be easily connected. In other words, in the case of the method of inserting cables inside the discharge pipe shown in the conventional example, the connection of the discharge pipe as the inner pipe arranged inside the main pipe is performed at the same time as the connection part of the discharge pipe. Strict watertightness and strength as a tension-resistant body when pulling back the excavator, the connection method required a lot of time and labor. Since the pipe is used as a pipe and the pulling-out pipe pull-out force does not actually work, it can be easily connected by a pin. Therefore, also from the above points, it is possible to simultaneously shorten the construction period and reduce the cost.

According to the third aspect of the present invention, when all the temporary pipe devices are buried, the entire cables extending together with the temporary pipe device can be pulled out. On the other hand, the main pipe can be easily buried by pushing the main pipe. Therefore, also from the above points, it is possible to simultaneously shorten the construction period and reduce the cost.

According to the fourth aspect of the present invention, there is provided a storage passage for storing cables, and the storage passage is openable and closable over the entire length thereof. Can be stored. Therefore, the same operation and effect as those of the first aspect can be obtained.

According to the fifth aspect of the present invention, since the storage passage is provided above the discharging pipe, the cables can be easily stored in the storage passage from above by opening the storage passage. . Therefore, also from this point, shortening of the construction period and reduction of cost can be achieved at the same time. In addition, since the storage passage serves as an upper surface spacer for holding the ground above the discharge pipe, the pushing force (propulsion) of the main pipe buried next to the temporary pipe device can be reduced.

According to the sixth aspect of the present invention, the storage passage, the left and right side surface spacers and the lower surface spacer are provided.
Since the periphery of the discharge pipe is surrounded by the spacer for retaining the ground, the pushing force (propulsion) of the main pipe buried next to the temporary pipe device can be further reduced. In addition, since the discharge pipes can be connected coaxially, the buckling strength of the connecting portion of the discharge pipes can be increased.

According to the seventh aspect of the present invention, since the storage passage is formed in a water-tight manner, the cables and the like stored therein can be kept in a clean state.

Further, this method requires that after all the temporary pipe devices 2 necessary for burying the main pipe 3 are buried, the cables 4 in the upper storage box 21 are extracted from either the front end side or the rear end side. Features.

Hereinafter, the method of burying a non-drilling pipe will be described in more detail. The method of burying a non-drilling pipe mainly includes a first step of burying the temporary pipe apparatus 2 and a second step of burying the main pipe 3.
It is divided into process steps. In the flow chart shown in FIG. 6, steps SP3 to SP4 mainly correspond to the first step, and steps SP8 to SP11 correspond to the second step.

First, the first step will be described with reference to FIGS. First, as a preceding stage of the first process, the starting shaft G1 and the reaching shaft G2 are respectively constructed on both sides of the section where the main pipe 3 is to be laid (step SP1), and the main pushing device 5 is installed in the starting shaft G1. (Step SP2). And 1
As the process, first, the excavation device (lead conductor) 1 and the excavation device
The temporary pipe device connector 6 and the temporary pipe device 2 are connected to connect the temporary pipe device 2
Is promoted (step SP3). At this time, the digging device 1

In addition, in FIG. 1, 9 is a hydraulic pump unit,
10 is an unloading hose, 11 is an unloading tank, 12 is an operation panel,
5a is a hydraulic cylinder that presses the temporary pipe device 2 in the main pressing device 5.

Then, after the excavating device 1 for driving and propelling the cutter head 7, the hydraulic cylinder 5a of the main pushing device 5 is provided.
By pressing the temporary pipe device, the temporary pipe device 2 is successively propelled in the direction of arrow A (the reaching shaft G2 side). Then, the digging device 1 finally arrives at the arrival shaft G2 (step SP4).

Next, the operation after the first step will be described with reference to FIGS. After the digging device 1 has reached the reaching shaft G2, the digging device 1 and the digging device-temporary pipe device connecting body 6 are recovered and removed on the reaching shaft G2 side (step SP5), and the hydraulic pump unit is provided on the starting shaft G1 side. 9. The cables 4 connected to the digging device 1 from the operation panel 12 through the upper storage box 21 are separated (step SP6).

Next, the removal process of the cables 4 will be described with reference to FIGS. The cables 4 are collectively pulled in and removed from the reaching shaft G2 using the winch 13 or the like (step SP7). However, this is only an example, and a means most suitable for the on-site environmental conditions may be used. Further, the cables 4 may be pulled out to the starting shaft G1 side. However, since the main pushing device 5 is still installed in the starting shaft G1, it is difficult to install the winch 13 or the like. Further, the discharging hose 10 and the discharging tank 11 on the starting shaft G1 side.
Remove and collect.

Next, the second step will be described with reference to FIGS. In the starting shaft G1, the temporary pipe device-main pipe connector 14 is connected to the rear part of the temporary pipe apparatus 2 located at the rear end (step SP8), and thereafter the main pipe 3 is sequentially added, and the hydraulic cylinder 5a moves in the arrow A direction. (Step SP9). At this time, on the arrival shaft G2 side, the removal and recovery work of the temporary pipe device 2 is performed simultaneously (step SP9).
The propulsion of the main pipe 3 and the recovery of the temporary pipe apparatus 2 are performed by the main pipe 3.
Until the vehicle reaches the arrival shaft G2 (step SP1).
0, 11). When the main pipe 3 arrives at the arrival shaft G2, the second step is completed. Since the holes are already formed and the cables 4 are not connected, this step can be performed at high speed. When the main pipe 3 reaches the arrival shaft G2, the temporary pipe device-main pipe connector 14 is finally removed and collected, and temporary facilities such as the main pushing device 5, the hydraulic pump unit 9, and the operation panel 12 on the starting shaft G1 side. All the types are removed and collected (step SP12), and a series of pipe laying steps is ended.

Next, the temporary pipe device 2 will be described in detail with reference to FIGS. Reference numeral 21 denotes an upper storage box 21, which also serves as an upper surface spacer for retaining the ground above the discharge pipe 22. 21a is another upper storage box 2
1 is an insertion socket provided in the upper storage box 21 itself for connection with the first storage box 21. Reference numeral 22 denotes a discharge pipe for discharging the earth and sand excavated by the digging device 1 to the rear, also serving as a driving force transmission pipe for transmitting the driving force from the hydraulic cylinder 5a to the digging device 1 side. Reference numeral 22a denotes an insertion socket provided on the discharging pipe 22 itself for connection with another discharging pipe 22.
Reference numeral 23 denotes a connection jig that serves as an attractive force transmitting portion between the temporary pipe devices 2 when the tube is pulled back. However, in normal work, the temporary pipe device 2
Is applied with a thrust in the compression direction from the hydraulic cylinder 5a.
It does not act on the connecting jig 23. This connecting jig 23
Are provided in the discharge pipe 22. Reference numeral 24 denotes side spacers provided on the left and right side surfaces of the discharge pipe 22 for holding the ground. Reference numeral 25 denotes a bottom surface spacer provided on the lower surface of the discharge pipe 22 for holding ground.

In FIGS. 9 and 10, the arrangement of the spacers 21, 24, and 25 is a cross when viewed in cross section. This takes into consideration the fact that the dry material is retained until the second process of the main pipe 3 is propelled, and this is not always the case depending on the installation environment. That is, a spacer may be provided so as to surround the discharge pipe 22 in a cylindrical shape. However, it is preferable to configure the upper storage box 21 described above by partitioning the inside of the spacer in a watertight manner.

The insertion socket 21a has a large clearance at the insertion portion, and a rubber seal O-ring (not shown) ensures watertightness at a connection portion of the upper storage box 21. If the water tightness of each of the upper storage boxes 21 connected to each other is continuously secured, it is possible to cope with curved propulsion. Further, the outer diameter of the discharge pipe 22 as the propulsion transmission pipe and the excavation diameter (creation pit wall diameter) by the cutter head 7 are significantly different (the excavation diameter is larger), but the upper storage box as the upper surface spacer. Since the constant propulsion shaft position can be secured by the downhole wall holding action by the 21, the side wall spacer 24 and the lower surface spacer 25, the buckling phenomenon at the connection portion of the temporary pipe device 2 can also be avoided. Also, the diameter of the pilot hole when the main pipe 3 is pushed in can be secured.

As shown in FIG. 7, the upper storage box 21 is opened and closed over its entire length in the longitudinal direction by an upper lid 21b. And the above-mentioned insertion socket 21a is in the state formed at the end of the upper lid 21b. The upper lid 21b is independent of the groove 21c of the upper storage box 21 formed integrally with the main body 20 of the temporary pipe device 2, and is attached to the main body 20 of the temporary pipe device 2 with bolts or the like. Upper lid 21
Rubber packing (not shown) is applied to the contact surface between the groove b and the groove 21b to ensure the watertightness of the upper storage box 21.

Next, a detailed description will be given of a process of connecting and propelling the temporary pipe device 2 with reference to FIGS. FIG. 15 is a flowchart showing this process. First, as shown in FIGS. 11 and 15, the temporary pipe device 2 is pushed into the ground by the hydraulic cylinder 5a, and then the main body 20 of the temporary pipe device 2 to be connected, that is, the temporary lid in a state where the upper lid 21b is removed. The pipe device 2 is inserted into the starting shaft G1. Then, the discharging pipe 22 of the temporary pipe device 2 pushed into the ground and the discharging pipe 22 of the temporary pipe device 2 to be added next are connected (step SP3-1). At this time, the discharge pipe 22 is in a state where the axis is aligned by the insertion socket 22a. That is, the buckling strength is increased.

Then, as shown in FIGS. 12 and 15,
Connect the cables 4 to the upper storage box 2 in the temporary pipe device 2.
1 in the groove 21c. At this time, since all the upper surfaces of the upper storage box 21 are open in the longitudinal direction, the cables 4 continuously extending from the temporary pipe device 2 can be easily and easily stored in the upper storage box 21.
That is, it can be inserted into the groove 21. next,
The upper cover 21b is inserted into the starting shaft G1 and
Into the groove 21c and connected to the main body 20 with bolts or the like. Thereby, the cables 4 are moved to the upper storage box 21.
(Step SP3-)
2). At this time, at the same time, the connecting jigs 23 provided on each of the discharging pipes 22 are connected to each other with pins, so that each temporary pipe device 2 is connected.
Are connected to each other (step SP3-3).

Next, as shown in FIGS. 13 and 14, the rear part of the discharging pipe 22 in the temporary pipe device 2 is connected to the hydraulic cylinder 5a.
And the temporary pipe device 2 is pushed into the ground. Then, when the temporary pipe device 2 is pushed out in this way, the hydraulic cylinder 5a is returned to the original position, and as shown in FIG. 11, the next temporary pipe device 2 is received in the starting shaft G1, and the connection operation described above is performed. repeat. Here, with respect to the process after connection of the discharge pipe 22, depending on the excavation speed and the amount of exposure of the temporary pipe device 2 to the starting shaft G1 side after being pushed out, even if the temporary pipe device 2 is being propelled, there is nothing to be done. In some cases, there is no problem, and the effect can be further exhibited.

The above embodiment is one example, and
It goes without saying that various changes or improvements can be made without departing from the spirit of the present invention. Also, cables 4
Can be supported by a continuous long one, but it goes without saying that the connection may be made on the way.

[0041]

As described above, according to the first aspect of the present invention, after the temporary pipe device is buried, the main pipe is pushed from behind the temporary pipe device and buried. When the main pipe is buried, the main pipe can be pushed with relatively low thrust, and only the main pipe needs to be added and connected. Therefore, high-speed connection by high-speed propulsion of the main pipe is possible.

When the temporary pipe device is buried, the storage passage can be opened and closed, so that the cables extending from the previously buried temporary pipe device are stored as they are in the storage passage of the next temporary pipe device. can do. That is, when adding the temporary pipe device, it is not necessary to add the cables, and at the same time, it is possible to use long cables. Therefore, it is possible to simultaneously shorten the construction period and reduce the cost.

Further, when a hydraulic hose, for example, is used as the cables, the number of couplers to be connected is reduced, so that the cost can be reduced and, for example, the hydraulic actuator mounted on the excavating device is used. The pressure loss of the working oil supplied to the (hydraulic motor) can also be reduced. That is, the mechanical efficiency can be improved.

As described above, since the pipe connection process can be performed easily and efficiently with high construction reliability, a large amount of labor is required for the pipe connection process, which has been a problem in the prior art. It takes time and power, or the number of tangent points of cable hoses increases due to the temporary pipe two-step method, the specification of the excavation equipment decreases, the cost of the temporary pipe equipment is high and there is no construction cost reduction effect. There is an advantage that it can be avoided.

According to the second aspect of the present invention, since the storage passage is a separate passage from the discharge pipe, cables can be easily stored in the storage passage and the connecting jig in the discharge pipe. Are connected by pins, the temporary tube device can be easily connected. That is, in the case of the method of inserting cables inside the discharge pipe shown in the conventional example, the connection of the discharge pipe as the inner pipe disposed inside the main pipe is performed at the same time as the connection of the discharge pipe. Strict watertightness and strength as a tension-resistant body when pulling back the excavator, the connection method required a lot of work.However, when the temporary pipe device of the present invention was used, the discharge pipe was disconnected. Since the pipe is used as a pipe and the pulling-out pipe pull-out force does not actually work, it can be easily connected by a pin. Therefore, also from the above points, it is possible to simultaneously shorten the construction period and reduce the cost.

According to the third aspect of the present invention, when all the temporary pipe devices are buried, the entire cables extending together with the temporary pipe device can be pulled out. By pushing the main pipe against the main pipe, the main pipe can be easily buried. Therefore, also from the above points, it is possible to simultaneously shorten the construction period and reduce the cost.

According to the fourth aspect of the present invention, since a storage passage for storing cables is provided, and the storage passage can be opened and closed over the entire length thereof, long cables can be stored as it is. Can be stored in the passage. Therefore, the same effect as that of the first aspect is obtained.

According to the fifth aspect of the present invention, since the storage passage is provided above the discharging pipe, the cables can be easily stored in the storage passage from above by opening the storage passage. it can. Therefore, also from this point, shortening of the construction period and reduction of cost can be achieved at the same time. In addition, since the storage passage serves as an upper surface spacer for holding the ground above the discharge pipe, the pushing force (propulsion) of the main pipe buried next to the temporary pipe device can be reduced.

According to the sixth aspect of the present invention, the storage passage,
Since the left and right side spacers and lower surface spacers surround the discharge pipe with the ground retaining spacer, the pushing force (propulsion) of the main pipe buried next to the temporary pipe device can be reduced. Further efforts can be made. In addition, since the discharge pipes can be connected coaxially, the buckling strength of the connecting portion of the discharge pipes can be increased.

According to the seventh aspect of the present invention, since the storage passage is configured to be watertight, it is possible to keep the cables stored therein in a clean state.
