Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic recording method and device for automatically recognizing a work state in a device for recording various data during a construction work in an embedding method.

[0002]

2. Description of the Related Art In a foundation pile foundation construction of a grounding auger method, an auger equipped with a bit having an injection hole at its tip is used to dig the pile while excavating it until the pile reaches a predetermined supporting layer. After that, the auger is rotated in the opposite direction to expand the excavation blade at the tip and at the same time, the cement milk is sprayed, the bit is pulled up at a predetermined speed, and an enlarged bulb with a diameter larger than a pile of a predetermined diameter and a predetermined strength is built. There is a root consolidation method.

In addition to this, there are various methods for embedding foundation piles such as pre-boring root consolidation, expanded root consolidation and rotary root consolidation.

In these methods, the record of the construction status is as follows: excavation depth, excavation torque, excavation time, ground support force,
The injection amount / pressure and time of water or cement milk, switching depth to cement milk / bit withdrawal speed, etc. are sampled.

This is for management inspection, or as reference data at the time of construction at the next construction site of the contractor, and depending on the construction, construction such as injection amount of cement milk / bit withdrawal speed is required due to legal regulations. This is because a standard may be set, and in this case, the injection amount of cement milk / bit withdrawal speed and the like may be recorded in real time and the record may be submitted to the orderer.

In order to efficiently collect the record of the construction status, it is necessary to start or stop the operation of the construction recording device in accordance with the construction timing of each pile.

At this time, needless to say, it is necessary to secure the personnel for operating the construction recording device, and because of the manual operation, the recording is forgotten or the recording timing is delayed, resulting in a defective recording.

On the other hand, in order to save labor, personnel for operating the construction recording device are omitted, and the construction recording device is kept in the operating state.
There is also a method of recording all day, but in this case, recording paper, flexible disk, and the like to be recorded are wasted, and a great deal of time and effort is required to cut unnecessary recording portions when preparing a report or the like.

[0009]

Therefore, by solving the above problems, the construction recording device is automatically set to the start state in accordance with the construction timing of each construction work requiring recording,
An object of the present invention is to provide a method and an apparatus for automatically stopping the recording at a timing when recording is unnecessary.

[0010]

Therefore, according to the present invention, among the measurement items that need to be recorded, the items whose measured data values are above a certain value at the time of work and below a certain value at the end, that is, the required recording time and Focusing on the fact that there are recording items that change synchronously, we found that the above problems can be solved by applying these signals as automatic switches and starting or stopping the construction recording device. .

As means, there is a storage device for storing various data from the sensor for a predetermined time at all times and updating the storage at fixed time intervals. When a plurality of data items are defined, and the value is equal to or greater than the set value and continues for the determined time or longer, recording including the memory from the predetermined time stored in the storage device is started, and the data is defined in the above. An automatic recording method and apparatus are characterized in that recording is stopped when the value of a single or a plurality of data items becomes less than or equal to a set value and continues for a predetermined time or longer.

Thus, if the power of the automatic recording device is turned on in advance, the required construction work record is automatically recorded, the number of personnel for operating the construction recording device can be reduced, and the recording unnecessary portion can be cut.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described by taking as an example an expansion rooting construction method in a medium excavation construction method among embedding construction methods.

Since the construction timing required to record the formation of the enlarged bulb and the flow rate of cement milk as a measurement item are synchronously linked, this measurement signal data is automatically recorded on the memory card 3 of the construction recording device 2. Used as a switch.

Here, the instantaneous flow rate above the set flow rate (example 1 liter / minute) is set by the signal from the flow meter 7 (set example 2).
If it continues continuously for more than 2 seconds), the recording to the memory card 3 of the construction recording device 2 is automatically started, and then the set flow rate (example 1 liter / minute) or less is reached and the set time (example 3 seconds)
In the case where the above continues, the recording on the memory card 3 of the construction recording device 2 is set to automatically stop.

A description will be given below with reference to the drawings.

FIG. 1 and FIG. 3 show a construction management system in an enlarged root consolidation method of a medium excavation method, which is one of the embodiments. That is, FIG. 1 shows the overall configuration of the management system, and FIGS. 2 and 3 show the software configuration.

FIG. 1 shows that the earth auger inserted into the hollow portion of the pile is rotated by the construction machine 1, the pile is sunk while discharging the earth and sand, and after the pile reaches the support layer, the auger is rotated in the reverse direction to make the tip end. This figure shows the outline of the overall structure of expanding the excavation blade of the section and spraying cement milk, lifting the bit at a predetermined speed, and constructing an expanded root-consolidating bulb having a diameter larger than a pile of a predetermined diameter and a predetermined strength. .

As an example of the construction management record during the construction of the expanded bulb, the amount of cement milk injected from the tip of the pile from the cement milk supply plant 4 through the electromagnetic flow meter 7, high pressure pump 5 and injection line 6 (electromagnetic flow meter). 7), the lifting stroke speed (from the stroke detector 9) and the injection pressure (from the pressure detector 8) are used as construction records to automatically record the necessary portions in the memory card 3.

FIG. 2 is a diagram showing an instantaneous flow rate of cement milk from the electromagnetic flow meter 7 which is used as an automatic switch signal to start or stop recording, as an example. For example, if the instantaneous flow rate continuously exceeds 1 liter / minute and 2 seconds or more elapse, 10
Recording of each measurement data on the memory card 3 including the data from the minute before second is automatically started. When the instantaneous flow rate continuously decreases to 1 liter / minute or less and 3 seconds or more elapses, recording on the memory card 3 is stopped. (It doesn't react to the instantaneous flow rate up and down.)

The construction management flow will be described below with reference to the flowchart of FIG. (Step 1) Press the start button and the construction recording device 2
Is turned on. (Step 2) A switch is selected so that the power of each measuring device is automatically turned on. (Step 3) The power supplies of various measuring devices are automatically turned on and the measurement is started. (Step 4) The measurement signal starts to flow into the storage device built in the construction recording device 2. (Step 5) In this example, the electromagnetic flow meter 7
The pressure detector 8 and the stroke detector 9 are attached, and the measurement signal is recorded as a construction record and sent to the storage device. (Step 6) The latest measured signals for the set time (example 10 seconds) are stored in this storage device, and at each set time (example 1).
Second) the measurement signal is updated. (Step 7) Among the measurement signals, the instantaneous flow rate of cement milk continuously exceeds the set flow rate (example 1 liter / min) and continues for the set time (example 2 seconds) or more, and continuously determines automatically. (Step 8) If not continued, the measurement signal is updated. (Step 9) If you continue for more than the set time (eg 2 seconds),
Automatically recognizes when construction starts. (Step 10) When the construction start is automatically recognized and determined, the set time of each latest stored measurement signal (Example 1)
0 second) minutes are sent to the memory card 3. (Step 11) Recording on the memory card 3 is automatically started. (Step 12) The measurement signal from each measuring device is sent to the memory card 3. (Step 13) Among the measurement signals, the instantaneous flow rate of cement milk is continuously lower than the set flow rate (example 1 liter / minute) and continuously determined for a set time (example 3 seconds) or more automatically. (Step 14) If not continued, recording of the measurement signal in the memory card 3 continues. (Step 15) When the set time (for example, 3 seconds) or more is continued, the construction completion is automatically recognized and determined. (Step 16) The memory card 3 is judged by the completion judgment of construction.
Recording is stopped. (Step 17) By pressing the measurement end button at the end of the work on that day, the power supplies of various measuring devices are automatically turned off and the measurement is stopped. (Step 18) Further, the power of the construction recording device is turned off.

By doing so, the record is always stored in the storage device built in the construction recording device 2 for a predetermined time (eg, 10 seconds) before the construction recording device is started. There is no time lag between recognition and recording.

Further, as an example of the embodiment, here, the measurement data recording start to the memory card 3 of the construction recording device 2 is started.
The stop was synchronized with the cement milk flow rate that is linked to the construction timing that needs to be recorded, but any signal that is linked to the construction timing may be used. It may be pressure.

By turning on the power of the device in advance, the construction recording device 2 automatically recognizes the construction timing in the expansion bulb building work of each pile for a predetermined time (eg, one day), and the measurement record is automatically recorded. It is possible to record only the required time.

[0021]

As described above, according to the method of the present invention, artificial problems such as time lag in construction recording, incomplete recording due to delay of recording timing, and forgetting of recording are eliminated, and recording is automatically performed without any mistake. Therefore, the number of personnel for operating the recording device can be reduced, and the waste of the recording medium such as the recording paper and the flexible disk is eliminated, and a great deal of labor such as cutting unnecessary recording portions when preparing a report or the like can be saved.
