Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a capital processing device for transferring construction data from a working device to a center device when a housing ground improvement work is carried out, or for shaving a pile contact surface of a columnar pile as a final step. The present invention relates to a housing ground improvement device provided.

[0002]

In the housing ground,
For example, a soil survey is performed in advance by measuring the penetration resistance of the soil in situ using a Swedish sounding tester or the like, measuring the hardness or tightness of the soil, and the configuration of the soil layer, and estimating the soil resistance. If the soil is determined to be soft ground as a result of the ground survey, the cement-based solidifying agent is slurried, and is mechanically mixed and stirred while being injected into the target ground, thereby solidifying the ground soil in a columnar manner. Ground improvement works are underway to strengthen the ground.

In such ground improvement work, it is preferable that information can be exchanged between a working machine used on site and a center device. As one example, Japanese Patent Application Laid-Open No. 6-173248 discloses a control system for a ground improvement device, which relates to so-called civil engineering work. This control system is to excavate the ground by rotating the auger, and in the ground improvement device for hardening the ground improvement material by stirring while injecting the ground improvement agent into the excavated hole, the excavation depth of the preset auger and Data such as excavation speed and excavation load, and construction plan data such as mixing ratio and flow rate of the ground improvement agent corresponding to the excavation depth are written into a 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 into the IC card, so that the construction daily report is made via a computer. Such reports can be created.

However, unlike the civil engineering work, the improvement work on the housing ground is relatively scattered over the site, so that information is transferred by an IC card, and the center device is centrally managed at one place. It is difficult to obtain information in real time. further,
It has also been pointed out that in the improvement work on the housing ground, trust in the contractor and reduced reliability have been pointed out, especially by hand-cutting work. It is. However, after extracting the IC card on which the construction data is written from the work machine, bring it to the transportation means such as mail or directly bring it, connect it to the computer in the office, and use the conventional method of sucking the construction data. On the way, there is a possibility that construction data different from the actual construction result is written to the IC card. 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 quickly by the center device.

[0005] On the other hand, in the conventional construction of a residential ground, a pile head processing step of shaving a pile head surface is performed as a final step after construction of a columnar pile. The outline of this processing step will be described with reference to the schematic diagram of FIG. 17. 1A and 1B are columnar piles formed on the housing ground, and 2 is a working machine. I have. In the lower part of the column 4, instead of the agitator 11, there is provided a scraper 7 for scraping the pile heads of the columnar piles 1A and 1B. Also, 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 is provided at a predetermined position of the column 4.
11 'is attached.

Here, a target pile level G2 is set such that the pile heads of the columnar piles 1A and 1B are cut off at a constant height h1 with respect to the basic reference level G1. The height h2 from the basic reference level G1 to the survey lens of the level gauge 11 is fixed and determined, and the target pile level G2 is set.
From the height to the surveying lens of the level 11 (h1 + h
2) is uniquely determined when the level gauge 11 is installed. Therefore, the index 11 'is attached vertically upward by the control height (h1 + h2) with respect to the lower end surface of the column 4. In this way, even if the construction floor is not constant,
If the column 4 is moved downward until the index 11 'coincides with the center line of the surveying lens while looking into the surveying lens of the level gauge 11, 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 performing the stigma processing while moving the column 4 by the work machine 2, level measurement is performed while looking into the survey lens of the level 11, and the index 11 'is positioned on the center line of the survey lens. When they match, another operator O 'notifies the operator O with a signal.
Is required. Therefore, a minimum of two people are required for the capital processing step, which hinders labor saving of the work.

[0008] The present invention is to solve the above-mentioned problems, and a housing capable of receiving the result of construction work by a working device to a center device side in real time without being falsified on the way. It is an object of the present invention to provide a ground improvement device.

It is another object of the present invention to provide a housing ground improvement apparatus which can save labor in the capital processing step.

[0010]

According to a first aspect of the present invention, there is provided a housing ground improvement apparatus for mixing and stirring a cement-based solidifying agent while injecting the same into a ground to solidify the ground soil. And a center device for centrally managing construction data sent from the working device via communication means, wherein the working device uses measurement results of each part during work as construction data as communication data. It is equipped with a mobile terminal to send to.

In this case, the center device can directly receive the construction data in real time simply by sending the measurement results of each part during the work to the communication means as construction data by the portable terminal provided in the work device at the site. . Therefore, unlike the transfer of the construction data by the conventional IC card, there is no possibility that the construction data is falsified on the way, and the construction data sent from the working device is
The center device can receive the information as it is in real time, and the center device 21 can process information sent from various places quickly. In addition, the mobile terminal can transmit construction data regardless of conditions within the reception area, so even in the case of improvement work on residential ground where the site is relatively widely scattered, construction data from multiple work devices can be transmitted. The reception can be reliably performed at the center device side, which is convenient.

According to a second aspect of the present invention, there is provided a housing ground improvement apparatus according to the first aspect, wherein construction data from the work device is stored in an Internet server connected to the communication means, and the Internet server is connected to the Internet server. The stored construction data is configured to be acquired by the center device.

In this case, since the construction data is exchanged via the Internet server, even if the construction data is transmitted simultaneously from a number of sites, the communication means on the Internet server side to be managed is almost congested. Does not happen.

According to a third aspect of the present invention, there is provided a housing ground improvement apparatus for forming a plurality of columnar piles by the working device, and further comprising a column with a vertically movable slicing machine for shaving the pile head of the columnar piles. Equipped with a pile head treatment device installed on the reference surface
A laser light projector for projecting a laser horizontal light that rotates 360 ° is provided, and a laser light receiver attached to the column and outputting a signal when receiving the laser horizontal light.

In this case, when the pile head surface of the columnar pile is scraped by the scraper while moving the column downward, the laser beam receiver that moves up and down together with the column catches the laser horizontal light from the laser beam projector. , A signal is output from the laser light receiver. Therefore, if this signal is recognized by the operator who operates the capital processing apparatus, the pile head of another pillar can be cut to the same level without the signal of another worker as in the related art.

[Explanation of Graph Monitor Screen] FIG.
When the graph screen switching button 44 is pressed, the display
16 is a graph monitor screen displayed in FIG. Here, a work number / pile number display section 61 that displays the work number and pile number currently being measured, respectively, and a graph display showing changes in the integrated flow rate, the integrated rotation speed, the injection pressure, and the depth during measurement in a graph. Part 62,
There is provided a current value display section 63 for indicating these current values by numerals. In the upper right part of the display screen, a scroll button for scrolling the graph section of the graph display section 62 in the left and right direction.
64 is provided, and a scale change button 65 for changing the horizontal axis scale (15, 25 or 40 m) of the graph section is provided at the lower right of the display screen. Since this graph monitor screen can be viewed when the client is at the site, there is an advantage that the actual construction status can be correctly explained to the client and that unauthorized construction is less likely to be performed.

When the work is started, the working machine 2 rotates the column 4 with the stirrer 11 forward to excavate the ground, and at the same time, injects the cement milk in a slurry state into the excavated hole to stir the cement milk. When the hole is dug to the depth designed according to the ground, the column 4 is rotated in the reverse direction and pulled out from the hole. When the cement milk reaches the designed injection volume, the injection is stopped there, but the stirring in the hole continues as long as the column 4 rotates. Once the column 4 is pulled out of the hole, the column 4 is pushed forward while rotating forward again to the designed depth, and then the column 4 is reversely rotated and pulled out. This promotes mixing of the cement milk in the holes. And column 4 2
When the reciprocating up and down movement is completed, one pile construction is completed and the cement milk is solidified as it is. In addition, since various environmental conditions are assumed outdoors at the site, the work machine 2 and the ground improvement work management device 13 and the display
16 is environmentally resistant (-20 to 75 ° C during storage, 0 during construction)
~ 55 ° C). In the excavation step, a rotation speed output of a pump (not shown) for injecting cement milk is displayed according to the excavation speed of the column 4. Thereby, appropriate cement milk can be injected.

At this time, on the graph monitor screen of the display 16 shown in FIG. 5, the depth of the column 4 is displayed on the graph display section 62 as a line graph. Further, the maximum depth of the column 4 and thus the pile can be understood by reading the value at the bottom of the graph display representing the depth. Therefore, if the graph representing this depth is substantially W-shaped, it can be confirmed immediately that the column 4 has been reciprocated twice as designed, and it can also be confirmed immediately whether the maximum depth is as designed. In addition, since a line graph showing the integrated flow rate of cement milk is also displayed on the graph display unit 62, by reading the value at the bottom of this graph, the total amount of cement milk injected into the hole can be confirmed. . In addition, column 4 is displayed in the graph display section 62.
Is displayed as necessary information.

[Description of Parameter Setting Screen] FIG. 6 is a parameter setting screen displayed on the display 16 when the parameter screen switching button 45 in FIG. 2 is pressed. Here, a scale setting display section 67 for setting display items such as depth, speed, rotation speed, press-fitting pressure, instantaneous flow rate, a tilt X axis, a tilt Y axis, and a maximum scale of the integrated flow rate, and change the setting of the current time are provided. And a destination telephone number setting display 69 for setting a destination telephone number.

FIG. 7 shows a memory card clear screen displayed on the display 16 when the memory card clear screen switching button 51 in FIG. 3 is pressed. There are a password input section 70 for inputting a password, and a memory card clear button for clearing the contents stored in the memory card 17 when the correct password is input to the password input section 70 and operated when the password input section 70 is operated. 71 and.

[Description of System] As described above, here, the cement-based solidifying agent is mixed and stirred while being injected into the ground.
A work machine 2 as a working device for forming a pile by solidifying the ground soil and a soil improvement work management device 13, and construction data transmitted from the ground improvement work management device 13 via a public communication line 14 as a communication means. The ground improvement work management device 13 includes a central device 21 for centralized management. The ground improvement work management device 13 is provided with a mobile phone 15 as a mobile terminal that sends out a measurement result of each part during work to the communication line 14 as work data.

In this way, the measurement result of each part at the time of work is simply sent to the telephone line 14 as construction data by the mobile phone 15 provided in the ground improvement work management device 13 at the site. Can be received directly in real time. Therefore, the conventional I
Unlike the transfer of the construction data by the C card, there is no possibility that the construction data is falsified on the way, and the construction data sent from the ground improvement construction management device 13 is received by the center device 21 in real time as it is. This makes it possible for the center device 21 to process information sent from various places quickly. Also, since the mobile phone 15 can transmit construction data regardless of conditions within the reception area, the mobile phone 15 is installed on a plurality of working machines 2 even in the case of improvement work on the housing ground where the site is relatively widely scattered. The construction data from the ground improvement construction management device 13 can be reliably received at the center device 21 side, which is convenient.

Further, since it is not necessary to exchange construction data by using an IC card, it is not necessary to install a personal computer on site. Also, construction data from sites scattered throughout the country can be centrally managed by one center device 21.

As is clear from the configuration of the display 16 in FIGS. 2 to 7, the measurement result of each part during the operation is not touched by the touch panel of the display 16 at all. Conversely, the ground improvement work management device 13 includes, as a software function, a change prohibition unit that prohibits a change in the measurement result of each unit during work. In this way, unless the software is replaced, the construction data cannot be falsified on site, and the center device 21 can receive accurate construction data.

[Explanation of Internet Server] When the work machines 2 are arranged at a plurality of sites, the transfer of construction data tends to concentrate in the evening when one day's work is generally completed. In this case, since one day's worth of construction data is sent from the site, there is a concern that the center device 21 is in a long-term call and the communication line 14 is likely to be congested.

FIG. 8 shows another embodiment in consideration of such concerns. In this alternative embodiment, the construction data sent from the ground improvement construction management device 13 sent out by the mobile phone 15 using the Internet server or the mail server 75 owned by the Internet provider connected to the communication line 14 as the communication line. Temporarily store the center device
Reference numeral 21 is configured to sequentially acquire construction data stored in the mail server 75. In this case, since the construction data is exchanged via the Internet mail server 75, even if the construction data is transmitted simultaneously from many sites, the communication line 14 on the mail server 75 side to be managed is congested. Rarely occurs.

[Description of laser beam projector and laser beam receiver used in the capital processing step] Next, FIG. 9 shows a schematic view of an apparatus for performing the capital processing step as the final step of the ground improvement work. In the figure, the conventional level
Instead, a projector having a 360 ° rotatable projector 81 for projecting a horizontal laser beam, that is, a laser beam projector 82
And a laser light receiver 83 as a light receiver attached to the column holding mechanism 5 which moves up and down together with the column 4. The laser beam receiver 83 may be attached to the column 4. The laser light projector 82 is installed on a basic reference level surface G1 serving as a reference surface, and when the laser light receiver 83 receives the laser horizontal light emitted from the light emitter 81,
A detection signal is sent to a ground improvement work management device 13 which is a control means. Further, the ground improvement work management device 13 includes a column depth monitoring means for monitoring the depth (height) of the column 4 in real time.

[Explanation of the system in the capital processing step]
In the above configuration, the laser beam receiver 83
The height up to the light receiving section, that is, the set length L, is
Ground improvement work management device 13 using the touch panel
Set to. As a result, the laser beam receiver 83 is
Column lowering amount L 'indicating how much column 4 should be lowered when laser horizontal light from 81 is received.
Is the control height (h from the target pile level G2 to the floodlight 81).
It is calculated by subtracting the set length L from 1 + h2).

Next, when the operator O sets the laser beam projector 82 on the basic reference level plane G1 and turns on the power,
The light projecting unit 81 emits laser horizontal light in 360 ° directions while rotating at a rotation speed of 600 rpm. Therefore, the laser light receiver 83 can receive the laser horizontal light from the laser light projector 82 at any position within the reach of the laser light (maximum 120 m) as long as there is no obstacle in the middle. The level accuracy required here is 0 to -20 mm, and the laser beam
The light receiving accuracy of ± 2.25 mm when the distance from the laser beam projector 82 is 30 m is used.

Thereafter, the operator O moves the column 4 of the working machine 2 up and down so that the laser horizontal light from the light projecting section 81 reaches the laser light 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 a depth display unit 28 provided in the display 16. Then, when the laser light receiver 83 receives the laser horizontal light 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 descent amount L '. to correct. Thereafter, by lowering the column 4 until the value of the depth display unit 28 becomes 0, the columnar piles 1A and 1B can be operated without the signal of another worker O 'as in the related art.
Can be cut down to the target pile level G2.
