Description

  The present invention is a system for supporting the extension of the life of concrete structures. Specifically, the built concrete structures in remote locations are inspected, and if there are any abnormalities, the state of deterioration is measured. The present invention relates to a system for extending the life of concrete structures.

  Conventionally, in order to inspect a built concrete structure in a remote place, an inspector visits the site and inspects it, and after the inspection is completed, returns to the management center and records it in the inspection book.

In recent years, portable and body-worn wearable computers equipped with cameras and microphones as disclosed in Japanese Patent Application Laid-Open No. 2002-297814 have been developed, and the situation of the site can be transferred to a management center or the like with images or sounds. It has become possible to send immediately.

  However, even though a wearable computer can immediately send a report in the field image and sound to the management center, analysis and evaluation based on the inspection results require a lot of time and effort. As a result, when another investigation item arises, there is a problem that it is necessary to go to the site again and re-inspect.

  In order to investigate the existence of individual deterioration of the main body / side wall / floorboard / ceiling / pillar, etc. of the built concrete structure, the present invention is designed to determine the age of the structure / concrete material / width / height / depth, etc. One or several host computers equipped with a database that stores the data of a large number of portable and body-worn wearable computers are connected by communication means such as the Internet, and individual concrete structures are connected to the wearable computers. Attach concrete tester means to check the presence of deterioration by hitting the location and elastic wave radar means to measure the position and size of deterioration by hitting concrete that may be deteriorated by inspection Removable, provided by the concrete tester means and elastic wave radar means to the host computer through the wearable computer The host computer is provided with a determination means for evaluating and determining the deterioration state of the concrete structure by receiving and analyzing the received inspection / measurement result, comparing with the database, and based on the evaluation / determination result of the deterioration state A measure selection means for selecting repair / reinforcement measures and a basic design means for making a basic plan for repair / reinforcement and design work in accordance with the selected repair / reinforcement measures. Since the individual data of structures and their detection results are combined into a three-dimensional diagram for display / output and a three-dimensional design means for automatically calculating the quantity required for the design, this problem has been solved. is there.

  The present invention is based on a concrete tester means for inspecting a concrete structure in a wearable computer having a form and a body mounted for use in inspecting a concrete structure in a remote place, and an elastic wave for measuring the deterioration state of the concrete. The radar means can be attached and removed freely, and the two-way simultaneous communication with the host computer makes it possible to recognize the on-site inspection status in real time and continue to measure the presence or absence of deterioration if there is an abnormality. Thus, the inspection / measurement result is collated with the database in the host computer and analyzed so that the evaluation / determination can be performed. Therefore, the inspection / measurement operation can be performed quickly and without waste.

  Since the host computer is equipped with a measure selection means for selecting repair / reinforcement measures based on the evaluation / judgment results, and a basic design means for creating a basic plan for repair / reinforcement and design work according to the selected repair / reinforcement measures. There is an effect that preparations such as repair can be started immediately.

  The evaluation / judgment means is equipped with a 3D design means that automatically displays the number of concrete structures in the database and the detection results, and displays / outputs the 3D diagram and automatically calculates the quantity required for the design. Therefore, it is possible to grasp the concrete structure three-dimensionally to make it easy to check the evaluation / determination and to accurately and automatically calculate the quantity of concrete and the like necessary for repair / reinforcement design.

  FIG. 1 shows an example of system construction of the present invention. A portable computer or a wearable wearable computer 1 possessed by an inspector who inspects a concrete structure is connected to a host computer 3 in a management center via an Internet line 2. Connected. The wearable computer 1 comprises a mounting unit 6 having a camera 4 and a microphone 5 mounted on a helmet or the like, and a body unit 10 having a monitor 7, a speaker 8 and character input / display means 9, and the mounting unit 6 and the body part 10 are connected by wire or wirelessly. A monitor 7 and a speaker (earphone) 8 may be provided in the mounting portion 6. 11 is a concrete tester means comprising a main body 11a and a hammer 11b for checking whether there is an abnormality by hitting the surface of the concrete structure, and 12 is a detailed check of the deterioration state by hitting the main body 12a, the sensor 12b and the concrete surface. The elastic wave radar means is composed of several types of impactors 12c having different weights for measurement. The concrete tester 11 means and the elastic wave radar means 12 are connected to the wearable computer 1 in a wired or wireless manner so as to be freely attached and detached. The inspected and measured numerical values are converted into signals and transmitted from the wearable computer 1 to the host computer 3 in real time. Commercially available products can be applied to the concrete tester means 11 and the elastic wave radar means 12.

  The host computer 3 is a database that stores and accumulates data such as the age, concrete material, width, height, depth, etc. of the main body, side walls, floor boards, ceilings, pillars, etc. of concrete structures built in various places. 3a so that the host computer 3 or the wearable computer 1 can extract the data of the corresponding concrete structure in the database 3a. The host computer 3 receives the inspection / measurement signal transmitted from the wearable computer 1, analyzes the presence / absence and detailed state of the concrete structure, evaluates / determines, and determines the evaluation / determination result. Measure selection means 3c for selecting a repair / reinforcement measure based on this, and basic design means 3d for making a basic plan and design work for repair / reinforcement in accordance with the selected repair / reinforcement measure. The judging means 3 is linked with the three-dimensional design means 3e used also when accumulating the database 3a, so that the situation / repair plan etc. of the concrete structure can be displayed and outputted in three dimensions.

  When inspecting a concrete structure, the wearable computer 1 and the host computer 3 are connected to each other via the Internet line 2, and the concrete structure is extracted from the database 3a. Inspect and inspect. In the inspection, when a concrete structure is struck with the hammer 11b of the concrete tester 11, as shown in FIG. 3, the action time in which the hammer 11b pushes the concrete surface and the reaction time in which the concrete pushes the hammer are the maximum impact force. It is expressed as a sine waveform with a vertex. If the sinusoidal waveform is almost symmetrical as shown in FIG. 3 (a), the concrete is in a healthy state, but when the action time is longer as shown in FIG. 3 (b), the surface deteriorates. In addition, as shown in FIG. 3C, when a plurality of vertices appear in the waveform, the concrete is peeled off. When such an abnormality appears, the elastic wave radar means 12 is connected to the wearable computer 1, the sensor 12b is pressed against the concrete surface, and the impactor 12c having an appropriate weight is matched to the concrete thickness. And hit the concrete surface. The waves generated by the impact propagate inside the concrete and are reflected multiple times in the thickness direction, and are repeatedly reflected between the impact point by the impactor 12c and the observation point of the sensor 12b, and the inside of the concrete having a thickness and deterioration. Since the position and size are measured in detail and the value is transmitted to the host computer 3, the determination means 3b compares and evaluates the received measurement value against the data at the corresponding location in the database 3a. Based on this measure, the measure selection means 3c selects the repair / reinforcement measure, and the basic design means 3d automatically performs the basic plan / design work for repair / reinforcement in accordance with this measure. The numerical values of these inspections and measurements and the results of various countermeasures, selections, designs, etc. derived from them are stored as additional data in the database 3a, and are displayed and output as a three-dimensional diagram, plan view, table, etc. showing deterioration. The information is displayed / output by a known means such as an apparatus, and after confirmation and examination, the actual work is started. All of these will be performed in a series in a single field inspection.

  As described above, the system of the present invention transmits the result of the nondestructive inspection / measurement by the concrete tester means and the elastic wave radar means to the host computer connected via the wearable computer, so that the concrete structure can be quickly detected. Because it is possible to detect abnormalities / deteriorations and quickly and accurately repair them, it can be used conveniently for the management of concrete structures in remote locations, etc., and support the extension of the life of concrete structures. It is something that can be done.
