Description

  The present invention relates to a caisson guidance management system and a caisson guidance management method using the caisson guidance management system.

  When the caisson is installed at a predetermined position such as underwater, generally, the water is poured into the caisson cage by a submersible pump in a floating state, the caisson is stabilized to a predetermined weight, and the caisson is moved to a predetermined position. After towing and guiding, a method is used in which water is poured further to cause the caisson to sink and install. At this time, since it is required to install the caisson at the target position as accurately as possible, the work manager performs water injection management on the caisson dredge, and also uses a transit or draft meter. When the inclination is measured and the caisson is suspended by a crane using a transceiver or the like based on the measurement result, an instruction is given to the crane operator to guide the caisson. Further, a method of managing the position of the caisson using a GPS system and guiding it to a predetermined position is also used (for example, see Patent Document 1).

JP 2004-238914 A

  However, in the method as described above, when the caisson shake is large, the position of the caisson is actually adjusted when the measurement is performed if guidance is performed using a transceiver or the like based on the measurement result of the transit or draft meter. A time lag occurs with time, and it is difficult to accurately guide the caisson to a predetermined position. Furthermore, in the method using the GPS system, the accuracy of guidance is lower than the method of direct measurement by transit, and reception of position information may become unstable due to increase or decrease in the number of available satellites.

  The present invention has been made in view of the above problems, and an object of the present invention is to accurately install a caisson at a predetermined position.

It is the flowchart which showed an example of the procedure which performs the guidance of a caisson using the caisson guidance management system which concerns on embodiment of this invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic view of a state in which water injection management of a new caisson 12 and guidance to a target position adjacent to an existing caisson 14 are performed using a caisson guidance management system 10 according to an embodiment of the present invention from a plan view direction. It is shown in. As shown in the figure, the caisson guidance management system 10 includes a biaxial inclinometer 18, a plurality of water level meters 20 installed for each ridge 22 provided in the new caisson 12, and a plurality of water levels. A data recording device 28 connected to all of the total 20 is provided. The existing caisson 14 includes two total stations 16 having an automatic tracking function and a system control unit 24 for controlling the entire system. The system control unit 24 calculates the system control unit 24. A monitoring monitor 26 for displaying information is connected. Further, both the new caisson 12 and the existing caisson 14 are provided with wireless communication means 30.

  Next, each component of the caisson guidance management system 10 will be described in detail. The two total stations 16 track the two omnidirectional mirrors 16a installed on the new caisson 12, respectively, measure the distance and angle, and the biaxial inclinometer 18 measures the tilt amount of the new caisson 12. measure. The plurality of water level gauges 20 measure the water level of the eaves 22 in which each is installed. For example, a water pressure sensor or the like is used. The water level data measured by the water level gauge 20 is all transmitted to the data recording device 28 and collected and recorded by the data recording device 28. In addition, the system control unit 24 acquires each measurement data measured as described above, and based on these measurement data, each information necessary for water injection management to the trough 22 and guidance of the new case 12 Is calculated and displayed on the monitor 26. For this reason, for example, a personal computer or the like is used for the system control unit 24, and operation with a mouse or a keyboard is possible.

  The wireless communication means 30 uses, for example, a wireless LAN, and establishes wireless communication between each device installed in the newly installed caisson 12 and each device installed in the existing caisson 14. In the illustrated example, since the water level data measured by the plurality of water level gauges 20 are collected in the data recording device 28, the water level data of each ridge 22 is not from each of the plurality of water level meters 20 but the data recording device. 28. If the data recording device 28 has a wireless communication function, the new caisson 12 is not provided with the wireless communication means 30, and is installed in each device installed in the new caisson 12 and the existing caisson 14. Communication with each device may be performed via the data recording device 28 and the wireless communication means 30 installed in the existing caisson 14.

  In the example shown in FIG. 1, the four wires 52 whose ends are fixed to the sinker 48 that is submerged in water are wound or wound by the four winches 40 fixed to the new caisson 12. By extending, the position of the newly installed caisson 12 in the floating state is adjusted. The four winches 40 are operated using the winch remote device 44 while confirming the guidance information system screen SD1 (see FIG. 2) displayed on the monitor 26 in the management room 50 on the existing caisson 14. Done by the administrator.

In addition, the amount of water injected into each ridge 22 of the newly installed caisson 12 is adjusted by pouring water from the water into the tub 22 or draining the water from the tub 22 into the water by four submersible pumps 42. . The operation of the four submersible pumps 42 is performed by the work manager using the pump remote device 46 while confirming the water injection management information system screen SD2 (see FIG. 3) displayed on the monitor 26 in the management room 50.

In addition, in the example of FIG. 1, 20 bottles 22 are provided in the newly installed caisson 12, and each of the five bottles 22 is divided into four water injection groups. And the five dredgers 22 of the same water injection group are connected by a water channel, and the injected water is shared within the water injection group. For this reason, by using at least four submersible pumps 42, the amount of water injected to all the dredgers 22 divided into four water injection groups is adjusted without changing the arrangement of the submersible pumps 42.

  Next, with reference to FIG. 2, an example of the guidance information system screen SD1 that the caisson guidance management system 10 according to the embodiment of the present invention displays on the monitoring monitor 26 by the system control unit 24 will be described. The guidance information system screen SD1 shows information for guiding the new caisson 12 to a target position adjacent to the existing caisson 14. First, the target position diagram TL shows the target position where the newly installed caisson 12 is installed, and the caisson installed at the target position is represented by a rectangle from the plan view direction. Further, in the target position diagram TL, target points TP1 and TP2 set to serve as indices for guiding the new caisson 12 are located on the rectangular end sides (in FIG. 2, the center and the left end of the right end side). It is displayed at the center of the side. The display position and size of the rectangle of the target position diagram TL and the target points TP1 and TP2 are fixed at least during the guidance work of the new caisson 12 while checking this system screen, and the information related to the target position is changed. Unless changed, there is no change in the guidance information system screen SD1. It is assumed that the position information of the target position is input to the system control unit 24 in advance or calculated by the system control unit 24 based on the positional relationship between the two total stations 16 and the target position.

  The current position diagram 12L shows the current position of the new caisson 12 as a rectangle from the plan view direction, and is set in the same manner as the target points TP1 and TP2 of the target position diagram TL. Displayed with NP2. Although the size of the rectangle in the current position diagram 12L is fixed, the display position and display angle of the rectangle correspond to the change in the actual positional relationship between the current new caisson 12 and the installation target position. It changes relatively in real time with reference to the position map TL. The actual positional relationship between the new caisson 12 and the target position is calculated by the system control unit 24 based on the measurement results of the two total stations 16 and the like. Further, in the current position diagram 12L, when the four corners of the upper surface portion of the newly installed caisson 12 are A to D, the four corner elevations FH indicating the respective heights are indicated by two total stations 16 and two-axis inclinometers. Based on the 18 measurement results, it is displayed at the corresponding apex corner of the rectangle. In the example of FIG. 2, it is assumed that A to D are set clockwise with the apex portion at the lower right of the rectangle of the current position FIG.

  In addition, the guidance amounts GP1 and GP2 displayed at the top of the guidance information system screen SD1 are the target points of the target position diagram TL from the guidance point NP1 of the current position diagram 12L, which serve as a guide when guiding the new caisson 12. The distance to TP1 and the distance from the guidance point NP2 to the target point TP2 are shown respectively. These distances are decomposed into the distance between the X direction and the Y direction, with the vertical direction in the guidance information system screen SD1 as the X direction and the horizontal direction as the Y direction, and the direction in which the new caisson 12 is guided. It is displayed with an arrow. These distances and the directions of the arrows are calculated by the system control unit 24 based on the measurement results of the two total stations 16 and the like.

Furthermore, the side inclination diagram CI1 displayed in the lower left portion of the guidance information system screen SD1 shows the current inclination amount when the newly installed caisson 12 is viewed from the side, together with a rectangle indicating the caisson viewed from the side. .
