Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a pipe burying method,
In particular, the present invention relates to an automatic recording method for automatically recording necessary conditions of the operating condition of a pipe burying device when burying a pipe.

[0002]

2. Description of the Related Art Conventionally, a pipe burying method using a pipe burying apparatus 1 as schematically shown in FIG. 1 has been widely used as a method for burying a water pipe, a conduit pipe, and other pipes used for various purposes in the ground. It has been implemented.

Pipe burying device 1 used in this burying method
Is installed on a guide rail 3 in a vertical shaft 2 excavated from the ground so that a drive unit 4 can move back and forth. The drive unit 4 rotationally drives an auger screw 5 to excavate the ground by an auger head 6 at its tip. At the same time, the propulsion device 7 (propulsion cylinder) pushes the pipes 10, 10 ... Which are to be embedded subsequently to the blade tip 8 and the tip conduit 9 while sequentially adding the pipes 10, thereby burying the pipe 10 in the ground. There is.

In the pipe burying method using the pipe burying device 1 described above, construction records such as displacement in the propulsion direction of the pipe 10, propulsive force, auger torque, etc. are taken at a fixed distance of the pipe burying. Is submitted to the orderer and is also used as reference material for construction at the construction site next to the contractor.

Conventionally, the operator records the above construction record in each state such as a propulsion state and an interruption state in accordance with each work procedure for propelling the pipe, and the operator finally judges and records the record in the management device 11 by manual operation. Has been done.

That is, when some operation of the pipe burying device 1 is used as a criterion for judging the state, the rotation of the auger screw 5,
The state at that time will be determined from a combination of operations such as promotion, adjustment, and correction.

[0007]

However, in the above-mentioned conventional state judgment, there are many combinations and it is almost impossible to make the judgment accurately when exceptional operations are taken into consideration.

[0008] Therefore, to impose these construction record operations on the operator has a problem that the operator's burden is increased because an input operation to the management device 11 is added to the main operation of burying the pipe.

[0009] In view of the above points, the present invention has been made to solve the problem that the management device automatically records a construction record when the pipe burying device is in a specific operation state, and the burden on the operator is greatly reduced. .

[0010]

As a means for solving the above-mentioned problems, the present invention is to rotate an auger screw by a pipe burying device to excavate a tip ground by an auger head at its tip, and to successively pipe at the excavation mark. In the pipe burying method of pushing and burying with a propulsion device while replenishing, the record information to the management device is automatically input on the condition of the combination of the operating state of each part of the pipe burying device and the propulsion position of the pipe by the propulsion device. It is characterized by having done.

The propulsion position is preferably within a range of an effective stroke when the propulsion device push-embeds a pipe.

[0012] As a result, if the pipe is in the process of being buried, the construction condition is automatically recorded in the pipe embedding device as long as the operating condition of the pipe embedding device (for example, the condition of normal rotation drive of the auger screw) is satisfied. When the above conditions are not satisfied, the operation is automatically stopped, so that the operator does not have to manually perform an input operation to the management device each time, and the operator's load is reduced.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the embodiments shown in the drawings.

In FIG. 3, the propulsion device 7 of the pipe burying device 1 is shown.
Since the front portion and the rearmost portion of the full stroke La are restricted by the dimensions of the vertical shaft 2, respectively, a “front dead dimension” and a “rear dead dimension” occur, and L excluding these is referred to as an “effective stroke”.

Further, 50 at the front of the effective stroke L.
Approximately mm is the "end area", the rear is the "start area", and the area between them is the "construction area". The “starting area” is a distance necessary for adding pipes 10 and the like.

When burying the pipe 10 by the pipe burying device 1,
In order to grasp the operation state, for example, the pushing operation A of the pipe 10 and the forward rotation operation B of the auger screw 5 are used as factors, and the propulsion by the propulsion device 7 is shifted from the "start area" to the "construction area" in FIG. The area condition C is added so that the operating state of the pipe burying device 1 can be grasped, and the above A, B,
When the three conditions of C are satisfied, the record of the operating state is automatically input to the tube embedding device 11.

As an exceptional work that requires recording and embedding, even when the drive unit 4 is retracted during propulsion to correct the course, as long as all of the conditions A, B, and C do not change, that is, When the three conditions are satisfied, for example, if the condition that the position of the propulsion device 7 is in the "construction area" is satisfied, the recording is continued.

In this way, the propulsion work is continued, the propulsion device 7 is moved to the "reset position (push-off position)", the "end area", the pressing operation is stopped, and the auger screw 5 is used.
When the three conditions that the driving of the drive has stopped have changed, the recording input to the management device 11 is stopped, the propulsion device 7 is disconnected, the drive unit 4 is retracted, and a new pipe 10 is set, and the propulsion device is restarted. When all three conditions of the pressing start by 7, the normal rotation of the auger screw 5, and the arrival of the propulsion device 7 in the "construction area" are satisfied, the input of the record to the embedding device 11 is restarted.

In this way, since the recording is made in addition to the condition that the propulsion device 7 is located in the "construction area", it is possible to record the operating state of the pipe burying device 1 without human intervention. It is possible to automatically input the data into the embedding device 11 and take a record.

FIG. 4 shows a flow chart of the above operation.

After the construction is started (step S ₁ ), ON / OFF of the manual recording start SW is checked (step S ₂ ), and when it is OFF, the automatic recording route is started.

Checking the status of "tube pushing operation"
(Step S_Three), Check the "normal rotation of auger screw"
Click (Step S_Four), "Propulsion device position" check
(Step S₅) Is made and all three of these conditions are met.
If so, automatic recording is performed by the tube embedding device 11.
(Step S₆). Step (S)_Three~ S₅) Izu
If any of them are not satisfied, the recording state will not be entered. Also
If you want to artificially interrupt recording, press the manual recording interrupt switch.
Turn on and off to interrupt recording (step
S ₇).

Unless the construction end SW (step S ₈ ) is turned on, recording is continued while any of these three conditions is satisfied while checking the above-mentioned three conditions, or recording is interrupted by the manual recording interruption switch. To enter the cycle.

If any of the pipe pushing operation (step S ₉ ), the auger screw forward rotation (step S ₁₀ ), and the position of the propulsion device (step S ₁₁ ) is turned on when the construction completion switch is off, It goes off the cycle and enters a loop that keeps track of individual records.

In the above embodiment, the pushing operation A of the pipe 10 and the normal rotation drive B of the auger screw 5 are preconditions for the recording requirement of the operating condition of the pipe burying device 1, but the replacement with another operating condition is required. Alternatively, addition is optional, and in that case also, it is essential to add the existing area (construction area) of the propulsion device 7 to the condition.

[0026]

As described above, according to the present invention, when recording the operation state of the pipe burying device during burying the pipe, the operation of the pipe burying device to record the operation is judged by the device itself. The automatic recording operation reduces the load on the operator and allows the operator to concentrate on the original propulsion work without being aware of the presence of the implantable device.
Moreover, since accurate information can be retrieved from the tube embedding device when necessary, it is possible to contribute to the improvement of construction quality.
