Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to design and construction of mountain retaining excavation work, etc.
This relates to a system that measures ground deformation and member deformation at each work site, and centrally manages the data measured at each work site at a measurement center.

[Prior Art] Due to the recent increase in the size and depth of excavation work and the increase in the number of construction works being carried out in close proximity to each other in urban areas, stricter planning and management than ever before are required in the design and construction of retaining stones. for example,
In conventional design, members were designed by simply considering the balance, but in today's mountain retaining calculations, the stress of the members is of course taken into consideration.
It is necessary to predict the amount of deformation with a high degree of accuracy, and advanced analysis methods using computers have come to be used at a practical level.

Under these circumstances, mountain retaining measurements are one of the safety management items to prevent accidents such as wall collapses and third party failures due to poor ground quality, as well as confirming the ground constants set at the time of planning. It also plays an important role in verifying analysis methods.

For this reason, in conventional mountain retaining measurements, personal computers are installed at multiple work sites to measure the inclination angle and strain of the excavated wall surface, and the data is processed by the personal computers. Based on the data obtained, we are able to respond to any problems and ensure that construction work can be carried out safely and as scheduled.

[Problem to be solved by the invention 1 Conventionally, when carrying out large-scale excavation work, personal computers were installed at each work site to measure the heap retaining, and data processing of measured values such as the angle of inclination of the excavated wall surface was carried out. . However, despite the installation of measuring equipment, data cannot be collected due to a lack of awareness and motivation for measurements among construction site staff, and the difficulty in securing technical staff due to the recent increase in the amount of construction work. Furthermore, even though data is collected, it is often difficult to make decisions based on data processing, so it cannot be utilized for construction management.

If such data cannot be collected or used for construction management, it will not be possible to predict the occurrence or causes of trouble during excavation work. As a result, problems could not be dealt with in advance, leading to accidents and problems with accuracy (impossible construction work).

Therefore, the present invention centrally manages the measurement data from each worksite at a measurement center, thereby making it possible to reliably and quickly respond to abnormalities and troubles in heap retaining, without being influenced by the various environments that differ from worksite to worksite. The aim is to make it possible to do so, and to achieve thorough labor savings in measurement work at each work site.

[Means for Solving the Problems] The present invention is a centralized management system for mountain retention measurement that achieves the above object. That is, measuring instruments such as inclinometers and strain meters are installed in each of a plurality of work sites, and data measured by these instruments at appropriate intervals is transmitted to a measurement center through an online system. At the measurement center, a computer collects and processes the received data, and the information obtained through the processing is sent by FAX to each work site for use in construction management at each work site.

[Operations] In the above-mentioned centralized control system for mountain retaining measurement, the computer located at the measurement center collects and processes the measurement data of each work site, so it is only necessary to place the technician who processes the computer at the measurement center. . For this reason, it is not necessary to assign a technician to each work site (but it is possible to process data accurately, improve construction accuracy, and quickly handle troubles. Since this data is centrally managed, it is also possible to judge the overall status of the mountain retaining work.

[Example] Embodiments of the present invention will be described with reference to the drawings.

Each work site for mountain retaining work is equipped with an inclinometer 1 that detects the inclination angle of the retaining wall and a strain meter 2 that detects strain on the excavation surface.
and a thermometer 3 are arranged, and measurements are taken with each measuring device at regular intervals. The measured value obtained by the measurement is input to the modem 5 via the local scanner 4. The modem 5 is controlled by a controller 6, and the input measurement values are automatically transmitted online using a telephone line 7 and input via the modem 9 to a personal computer 8 installed at the measurement center. Note that this personal computer 8 also controls the controller 6, and transmits data from the local scanner 4 to the personal computer 8 at regular intervals.

At the measurement center, there is a technician who operates a computer, and a personal computer 8 processes the data of measurement values input from each work site at regular intervals, converts and records them into slope angles and strains for each depth, and further In addition to converting it to the value of the strut axial force, the deformation diagram of the retaining wall is automatically drawn. In this way, the measured values at each work site can be centrally managed, and engineers can send the obtained data and drawings from the measurement center to each work site by FAX 10, and have them used for construction management at each work site. .

In addition, the engineer makes a comprehensive judgment based on the obtained data, etc.
If trouble is anticipated, that information will also be sent to each work site. In addition, each work site is responsible for maintenance, inspection, and maintenance of each measuring instrument.
Alternatively, engineers can be sent around by car to respond to abnormal values.

[Effects of the Invention] According to the centralized control system for mountain retaining measurements of the present invention, the measurement data of each work site is centrally managed at the measurement center, so that data can be processed accurately by simply assigning an engineer only to the measurement center. management and can quickly respond to problems. In addition, by centrally managing data at the measurement center, it is possible to grasp the status of the entire system, making it easier to discover and respond to measurement problems such as cable breaks. As a result, the reliability of measurement results is dramatically improved, making it possible to perform high-quality construction management, which is the original purpose of measurement.
