Japanese Patent Laid-Open No. 11-11868

The management method in the case of placing concrete using a crane as disclosed in Patent Document 1 described above cannot be employed in a construction method in which concrete is transported and placed by a dump truck.
On the other hand, the concrete placement state and the placement position management method of the present invention are made in order to solve the problem in the case of placing concrete on a wide site using a transportation means such as a dump truck. .

In order to solve the above-described problems, the concrete placement state and placement position management device of the present invention is a device installed in a concrete plant, and a device for inputting and transmitting concrete data, and a concrete Conveying equipment that can receive information from the plant and can send concrete placement position, placement time, concrete information obtained from GPS information to the field office, transport concrete, and place it on site, and depth A compaction device equipped with a gauge, which is a depth meter installed in the vibrator for detecting the insertion depth of the vibrator into the concrete, and a device installed in the operation unit of the compaction device. a device for transmitting a hardening depth and compaction time to the site office, an installed device in the field of office, position information from the conveying device And enter the concrete data record, in which is characterized in that their data consisted output apparatus capable as mesh diagram.
Moreover, the concrete management method of the present invention uses the management device described above, and outputs a mesh diagram from the data transmitted from the transport device to the field office and the data transmitted from the compaction device to the field office. It is characterized by that.

Since the concrete placement state and the placement position management method of the present invention are as described above, the following effects can be obtained.
<1> Since a series of concrete placement positions and information on the placed concrete can be managed regardless of human power, significant labor savings can be expected.
<2> Since the collected information can be centrally managed, it can be fed back to the site where concrete is placed in real time. For this reason, it is possible to grasp and confirm the progress status regardless of where the installation number or supervisor is on the site, and the work efficiency can be improved.
<3> It is possible to effectively cope with and apply a large amount of high-speed construction expected in the near future.

  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

<1> Overall Configuration The management device of the present invention basically includes a transmission device installed in the concrete plant 3, a reception / transmission device installed in the transport device 4, a reception / transmission device installed in the site office 1, It is comprised with the transmission / reception apparatus installed in the operation part of the compaction apparatus of the placement site 2. FIG.

<2> Plant Transmission / Reception Device A plant 3 that manufactures concrete is provided with a transmission device that inputs kneaded concrete data and transmits the data to the transport device 4.
The concrete information in this case can be automatically input from various instruments installed in the plant 3 to the transmission device, or can be input manually.

<3> Reception / Transmission Device of Transport Device The concrete transport device 4 is equipped with a reception / transmission device that can input, record, and display data of ready-mixed concrete shipped from the plant 3.
Information on the concrete currently being conveyed can be transmitted from this device to the site office 1 or to the compaction device at the placement site 2.
Further, when the transport device 4 arrives at the placement site 2 and discharges the concrete, the discharge, placement position, placement time, and information on the placed concrete can be transmitted to the site office 1. .
The information on the placement position at the site 2 is obtained from the GPS information, specifies the position, and transmits the information to the site office 1.

<4> Compaction device The compaction device is a known device that mounts a vibrator and vibrates the concrete by the vibrator to compact the concrete.
The compaction device is equipped with a depth meter.
An ultrasonic distance meter can be used as the depth meter.
This depth meter can detect the insertion depth of the vibrator of the compacting device into the concrete.
Furthermore, the operation unit of the compacting device is equipped with a receiving / transmitting device capable of transmitting information regarding the insertion depth of the vibrator into the concrete and the vibration time to the field office 1.

<5> Apparatus Installed in the Field Office The field office 1 is provided with a transmission / reception apparatus that can receive data from the transmission / reception apparatus of the transport device 4 and data from the reception / transmission apparatus of the compaction apparatus.
With this device, it is possible to collect information such as information on the composition of concrete placed at a place on the placement site 2, information on the placement time, information on the placement position, compaction time, and the insertion depth of the vibrator. it can.
Furthermore, a mesh diagram can be created and output from these pieces of information.

<6> Mesh Diagram The mesh diagram output from the transmission / reception device installed in the field office 1 is, for example, as shown in FIG.
This mesh diagram divides a wide site into a number of sections, and displays the excitation time by the compaction device for each section.
This mesh diagram is drawn based on data such as the XYZ coordinate value of the placement position, the placement time at that position, the compaction time, the batch number of the placed concrete, and the concrete blending information for each batch. The

<7> Management method Next, the management method of the concrete placement state using said apparatus is demonstrated.

<8> Information to the conveying device The mixing information of the concrete for each kneaded batch is transmitted from the plant 3 to the conveying device 4 and recorded in the receiving and transmitting device of the conveying device 4.
In this way, the transporting device 4 records the mix of concrete currently loaded and transported.

<9> Transmission from the transporting device When the transporting device 4 arrives at the predetermined placement site 2, it discharges and places the loaded concrete.
Information on the placement position at that time can be acquired from the GPS information.
If it is placed at the site 2, the placement time, the placement position, and the composition information of the placed concrete are transmitted from the transport device 4 to the site office 1.

<10> Transmission from compaction device When concrete compaction starts on site 2, information such as the time, compaction time, and vibrator insertion depth is transmitted from the compaction device receiving / sending device to site office 1. .

<11> Site Office A signal transmitted from the transport device 4 is input to the receiving / transmitting device of the site office 1 near the placement site 2.
That is, information on the composition of concrete placed at a certain point, information on the placement time, information on the placement position, and the like.
Further, information such as compaction time and vibrator insertion depth transmitted from the compaction device is input.
Based on these information, that is, the XYZ coordinate value of the placement position, the placement time at that position, the compaction time, the batch number of the placed concrete, the blending information of the concrete for each batch, etc. Create, display it, and output it.
Including the mesh diagram, it is possible to manage the placement state on a wide site from other information.
