[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stigma processing device for transferring construction data from a working device to a center device when a residential ground improvement work is carried out, or as a final step for scraping off the pile-like surface of a columnar pile. The present invention relates to a residential ground improvement device.

[0002]

[Problems to be Solved by the Invention] In the residential ground,
For example, a ground survey is carried out in advance by measuring the penetration resistance of soil in-situ using a Swedish sounding tester or the like, measuring the hardness or softness, the degree of tightness, and the composition of the soil layer, and estimating the bearing capacity. Then, as a result of this ground survey, when it is judged that the ground is soft, the cement-based solidifying agent is made into a slurry state, and the ground soil is solidified into a columnar shape by mechanically mixing and agitating while pouring it into the target ground. Ground improvement work is underway to strengthen the ground.

By the way, in such ground improvement work, it is preferable that information can be exchanged between the working machine used in the field and the center device. As an example of this, Japanese Patent Laid-Open No. 6-173248 discloses a control system for a ground improvement device, which is related to so-called civil engineering work. This control system rotates the auger to excavate the ground, stirs while injecting the soil improving agent into the excavated hole, and stirs the soil improving material to harden the soil improving material. The data such as the excavation speed and the excavation load, and the construction plan data such as the mixing ratio and the flow rate of the ground improvement agent corresponding to the excavation depth are written in the IC card from a computer as a center device installed in an office or the like. And this I
When the C card is inserted into the work machine at the site, the work is automatically performed based on the construction plan data input to the IC card, and the actual construction data is written in the IC card, so that the construction daily report is sent via the computer. It is possible to create a report such as.

However, unlike such civil engineering work, since the site for the improvement work of the residential ground is scattered over a relatively wide area, the center device is centralized and managed in one place when the information is transferred by the IC card. It is also difficult to obtain information in real time. further,
It has been pointed out that in the improvement work of the residential ground, the distrust of the contractor and the decrease in reliability are especially pointed out by the omission work, and it is necessary to send the result of the work done by the work machine to the center device as it is without being falsified on the way. Is. However, in the conventional method in which the IC card in which the construction data is written is taken out from the working machine, and then brought by a transportation means such as mail or directly, and connected to the computer in the office to suck up the construction data. Construction data different from the actual construction result may be written in the IC card on the way. In addition, since the center device cannot obtain information in real time, there is a problem that construction data from various places cannot be processed speedily on the side of the center device.

On the other hand, in the conventional construction work for improving the residential ground, a pile head treatment step is carried out as a final step after the pillar piles are constructed to scrape off the pile head surface. The outline of this treatment process will be described with reference to the schematic view of FIG. 17. 1A and 1B are columnar piles formed on the residential ground, and 2 is a working machine. Here, the columnar pile 1A is used to scrape the pile head surface. There is. A shaving device 7 for shaving the pile head surfaces of the columnar piles 1A and 1B is provided in the lower portion of the column 4 instead of the agitator 11. A level gauge 11 for leveling is installed on the ground of the basic reference level G1, while an index to be watched from the level gauge 11 at a predetermined position of the column 4.
11 'is attached.

Here, the target pile level G2 is set so that the pile head surfaces of the columnar piles 1A and 1B are shaved off at a constant height h1 with respect to the basic reference level G1. Also, the height h2 from the basic reference level G1 to the survey lens of the level 11 is fixed and fixed, and the target pile level G2
Control height (h1 + h)
2) is uniquely determined when the level 11 is installed. Therefore, with the lower end surface of the column 4 as a reference, the index 11 'is attached vertically upward by the management height (h1 + h2). In this way, even if the construction floor is not constant,
If the column 4 is moved downward while looking through the survey lens of the level indicator 11 until the index 11 'coincides with the center line of the survey lens, the columnar pile 1A can be scraped to the height of the target pile level G2.

However, in the above configuration, in addition to the operator O who performs the stigma processing while moving the column 4 by the work machine 2, level surveying is performed while looking through the survey lens of the level indicator 11, and the index 11 'is on the center line of the survey lens. When they match, another operator O ', which gives a signal to the operator O,
Is required. Therefore, the stigma treatment process requires a minimum of two people, which is an obstacle to labor saving.

The present invention is intended to solve the above-mentioned problems, and in the improvement work of the residential ground where the site is scattered over a relatively wide area, the result of the work device being tampered with is tampered with on the way. It is an object of the present invention to provide a residential ground improvement device that can be received by the center device side in real time as it is, without fail, and can reliably receive construction data from a plurality of work devices on the center device side.

Conversely, the ground improvement work management device 13 includes, as a software function, a change prohibition unit that prohibits the change of the measurement result of each part during work. In this way, unless the software is replaced, the construction data cannot be tampered with at the site, and the center device 21 can receive the accurate construction data.

[Explanation Regarding Internet Server] By the way, when the working machines 2 are arranged at a plurality of sites,
The transfer of construction data generally tends to concentrate in the evening when the work of the day ends. In this case, since the construction data for one day is sent from the site, there is a concern that the communication line 14 is likely to be congested because the center device 21 has been talking for a long time.

FIG. 8 shows another embodiment in consideration of these concerns. In this other embodiment, the construction data from the ground improvement construction management device 13 sent by the mobile phone 15 is utilized by utilizing the internet server, that is, the mail server 75 owned by the internet provider connected to the communication line 14 which is the communication line. Temporarily store the center equipment
Reference numeral 21 is configured to sequentially acquire the construction data stored in the mail server 75. In this case, since the construction data is transferred via the mail server 75 via the Internet, even if the construction data is transmitted from many sites all at once, the communication line 14 on the side of the mail server 75 to be managed will be congested. Rarely happens.

[Description of Laser Light Projector and Laser Light Receiver Used in Stigma Treatment Step] Next, FIG. 9 shows a schematic view of an apparatus for performing the stigma treatment step as the final step of ground improvement work. In the figure,

However, the control height from the target pile level G2 to the floodlight 81 (h
It is calculated by subtracting the set length L from 1 + h2).

Next, when the operator O installs the laser light projector 82 on the basic reference level surface G1 and turns on the power,
The light projecting section 81 projects horizontal laser light in 360 ° directions while rotating at a rotation speed of 600 rpm. Therefore, the laser light receiver 83 can receive the horizontal laser light from the laser light projector 82 at any position within the reach of the laser light (up to 120 m) unless there is a shield in the middle. The level required accuracy here is 0 to -20 mm, and the laser light receiver 83
The light receiving accuracy of is 2.22 mm when the distance from the laser light projector 82 is 30 m.

Thereafter, the operator O vertically moves the column 4 of the working machine 2 so that the horizontal laser beam from the light projecting section 81 reaches the laser beam receiver 83. At this time, the column depth monitoring means monitors the depth of the column 4, and the value is displayed in real time on the depth display section 28 provided in the display unit 16. Then, when the laser light receiver 83 receives the horizontal laser beam and outputs a detection signal to the ground improvement work management device 13, the ground improvement work management device 13 sets the value of the depth display unit 28 to the column descending amount L '. to correct. After that, if the column 4 is lowered until the value of the depth display section 28 becomes 0, each pillar-shaped pile 1A, 1B can be obtained without the signal of another worker O'as in the conventional case.
It is possible to scrape the pile head surface of to the target pile level G2.

A laser light projector 82 installed on the basic reference level surface G1 and a laser light receiver 83 attached to the column 4 or the column holding mechanism 5 for receiving horizontal light from the laser light projector 82. When the laser light receiver 83 receives the horizontal light, the operator O is informed of the descending amount L ′ of the column 4 up to the target pile level G2.

The horizontal light from the laser light projector 82 is directed to the column 4
Alternatively, the laser light receiver 83 attached to the column holding mechanism 5
Laser light receiver 83
When O receives the horizontal light, the operator O can know how much the column 4 should be further lowered. Therefore, unlike the conventional case, it is not necessary to send another worker O'to the site, and labor saving of the personnel can be achieved in the stigma processing step. Although leveling is performed using horizontal laser light in the embodiment, horizontal light of other wavelengths may be used.

That is, as a pile head treating apparatus having a column 4 with a vertically movable shaving device 7 for scraping the pile head surfaces of the pillar piles 1A and 1B after forming a plurality of pillar piles by the working machine 2. Working machine 2 and ground improvement work management device 13 of
There is a device provided with a laser light projector 82 for projecting horizontal laser light installed on the reference surface and a laser light receiver 83 mounted on the column 4 and outputting a signal when the horizontal laser light is received. For example, when the column heads of the columnar piles 1A and 1B are scraped off by the scraper 7 while moving the column 4 downward, the laser light receiver 83 moves up and down together with the column 4.
Captures the horizontal laser light from the laser projector 82,
A signal is output from the laser light receiver 83. Therefore,
If this signal is recognized by the operator O who operates the stigma processing device, the pile head surfaces of other columnar piles can be scraped to the same level without the signal of another worker O'as in the conventional case.
