[0024]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, specific examples of the present invention will be described with reference to the drawings.
[0025]
As shown in FIG. 1, a pavement manager 10 who manages pavement requests an underground survey of a pavement surface to an external surveying organization 20 several times a year, for example, as shown in FIG. Provide the survey results to the pavement manager 10.
[0026]
The research organization 20 basically lends or transfers a radar 210 for exploring an underground abnormality to a pavement manager 10 for managing a pavement surface.
[0027]
The pavement manager 10 mounts the radar 210 on the patrol car 100 that regularly checks and paves the pavement road surface. The patrol car 100 is equipped with a global positioning system (GPS) for specifying a geographical position using radio waves from artificial satellites.
[0028]
A GPS is linked to the rented or transferred radar 210, so that a geographical position of an abnormal location can be specified.
[0029]
Hereinafter, the case where the underground abnormality is a cavity generated underground on a pavement surface will be described as an example.
[0030]
The patrol vehicle 100 travels on a traffic point such as a paved road or a plaza, and performs a primary survey for exploring a wide range of outlines of the location and spread of the cavity.
[0031]
In this example, the radar 210 can search the underground with a width of about 2.5 m. Therefore, if the radar 210 travels in the center of the lane and searches, the lane can be covered. That is, in the case of a one-lane road, the search is completed by traveling once, and in the case of a three-lane road, for example, the search is completed by traveling three times.
[0032]
Further, the radar 210 can search underground at least about 1.5 m below the road surface.
[0033]
In a general pavement road, the pavement has a thickness of about 80 cm, and soil, sand, crushed stones, and the like are laid under the pavement with a thickness of about 80 cm. Pipes such as water pipes and gas pipes are buried therein.
[0034]
Thus, the radar 210 is capable of exploring cavities present in soil, sand, crushed stones, etc., about 70 cm below the pavement.
[0035]
The traveling speed when the patrol vehicle 100 performs the primary survey is about 45 km / h. Thus, extensive exploration of the cavity is possible without obstructing general traffic.
[0036]
Then, the data obtained by this exploration is sent to an analysis center 200 that performs data analysis of an external research organization 20.
[0037]
The research organization 20 analyzes the data obtained by the exploration and grasps the underground condition of the pavement road surface.
[0038]
Next, a case where the research organization 20 performs a detailed search (secondary search) as necessary will be described. For example, in the first survey, a second survey is conducted at a location where a cavity is found underground.
[0039]
For the secondary investigation, a maintenance directly managed vehicle 220 owned by the investigation organization 20 is used. The maintenance directly-managed vehicle 220 is used when a survey is requested or in an emergency, and is a vehicle that performs underground exploration while traveling at about 10 km / h.
[0040]
In this example, six underground radars 230 are provided in parallel at the front of the maintenance directly managed vehicle 220, and six images of the cavity corresponding to the underground radars 230 in each place are obtained. As a result, a two-dimensional image of the cavity is obtained.
[0041]
In addition, since the maintenance-managed vehicle 220 is equipped with a GPS and is linked to the underground radar 230, the geographical position of the cavity can be specified.
[0042]
The underground radar 230 has a width of at least about 2 m and is capable of exploring underground about 1.5 m below the road surface.
[0043]
It is to be noted that the maintenance directly managed vehicle 220 may be directly dispatched by the research organization 20 or may be lent to the pavement manager 10 and the pavement manager 10 may be dispatched.
[0044]
When the research organization 20 lends the radar 210 or the directly managed vehicle 220 to the pavement manager 10, the rent is paid from the pavement manager 10 to the research organization 20.
[0045]
Secondary surveys include, for example, a mesh survey to explore the location and extent of the cavity using the underground radar 230, a boring survey to observe the walls up to the cavity with an in-hole imaging device called a doroscope, and a void inside the cavity. Examples include scope surveys and the like, which are observed using an illuminated imaging device called a scope.
[0046]
The mesh survey is performed as follows.
[0047]
A road surface photographing device 240 for photographing a road surface image is provided on the roof of the maintenance directly managed vehicle 220.
[0048]
First, a process of combining a two-dimensional image of a cavity obtained by the radar 230 with a mesh is performed.
[0049]
The two-dimensional image of the cavity in which the mesh is combined and the road surface image captured by the road surface imaging device 240 are combined by a computer mounted on the vehicle.
[0050]
This allows the investigator to grasp the location and extent of the cavity.
[0051]
The drilling survey is performed as follows.
[0052]
A hole is drilled in the pavement at the location where it is determined in the primary survey that a cavity has occurred.
[0053]
Then, a doroscope is inserted into the small hole, and the wall surface from the pavement road surface to the cavity is photographed and recorded in an image. Thereby, the depth to the cavity can be grasped.
[0054]
The scope survey is performed as follows.
[0055]
Using a small hole on the pavement surface drilled in the boring survey, a void scope is installed in the cavity, and the wall surface inside the cavity is photographed and recorded in an image.
[0056]
This makes it possible to determine the priority of repairing the cavity (repair priority determination).
[0057]
For example, when the wall surface inside the cavity is severely collapsed, if it is left as it is, it is highly likely that the cavity will collapse.
[0058]
The maintenance directly managed vehicle 220 has the same function as that in the analysis center 200, and among them, data analysis is possible similarly to the analysis center 200. For example, the items listed in the menu 250 are performed.
[0059]
That is, the data obtained by the underground radar 230 is automatically analyzed, and when an abnormality is found, the probability that the abnormality is a cavity is calculated and presented ((1) Automatic analysis (probability presentation) )).
[0060]
In this case, the result of the comprehensive analysis of the cavity has been obtained with a probability of 90% or more as the previous result ((2) Comprehensive analysis determination (probability of 90% or more)).
[0061]
Next, the scope inspection described above is performed, and the repair priority of the cavity is determined ((3) Use of void scope (repair priority determination)).
[0062]
Then, the result of the analysis by the maintenance directly managed vehicle 220 is compared with the analysis result calculated in the analysis center 200, and the consistency between the two is confirmed.
[0063]
In addition, the pavement manager 10 can arbitrarily select a secondary survey from three types such as a radar survey, a boring survey, and a scope survey.
[0064]
This is intended to facilitate the pavement manager 10 who excavates a cavity occurrence location without performing all three types of secondary investigations when a cavity is found in the primary investigation.
[0065]
In addition, in a secondary investigation in an emergency such as when a collapse accident occurs on a paved road suddenly, the research organization 20 may dispatch the maintenance directly operated vehicle 220.
[0066]
The result of the primary survey is analyzed by the analysis center 200 based on the request of the user of the patrol vehicle 100, and the data collected by the patrol vehicle 100 is reported to the pavement manager 10.
[0067]
The results of the secondary survey are collected and analyzed by the maintenance vehicle 220 and sent to the analysis center 200 for analysis and confirmation. The result is reported to the pavement manager 10 via the maintenance vehicle 220.
[0068]
Next, a case will be described in which the radar 210 is lent or transferred to a person outside the research organization 20 (including the pavement manager 10), and the outside person uses the radar 210 to search underground on the pavement road surface.
[0069]
The research organization 20 obtains data obtained by exploration from an external person and analyzes the data to grasp the underground condition of the pavement road surface.
[0070]
This eliminates the need for the research organization 20 to search in order to obtain data, and the research organization 20 can save money for this. In addition, an outsider who conducts exploration can earn income by selling the data.
[0071]
Next, in the underground survey system 1 in which the surveying organization 20 that conducts a survey of the underground surface of the pavement provides the survey result of the underground surface of the pavement to the pavement manager 10, the surveying organization 20 determines the number of cavities that are abnormal underground. The case where the survey fee is determined according to the following will be described.
[0072]
That is, in the underground survey system 1 according to the present invention, the pavement manager 10 surveys the underground, analyzes the obtained data, and determines the survey fee according to the number of cavities. Thereby, the pavement manager 10 can investigate all the road extensions to be managed with a low budget.
[0073]
Based on past cases, the research organization 20 stores data on the cavities of each pavement manager 20, for example, the history of the occurrence of cavities in the same location, the situation around the location such as the presence or absence of buried pipes, etc. as a database. . Thereby, it is possible to give advice on the repair method.
[0074]
Hereinafter, other embodiments will be described. In other embodiments, the same portions as those in the above-described embodiment are denoted by the same reference numerals, and description thereof will be omitted.
[0075]
In the above-described embodiment, the underground abnormality of the pavement surface has been described by taking a cavity as an example.However, the present invention is not limited to this, and it is possible to similarly deal with the case of water leakage from a water pipe buried underground. it can.
[0076]
As described above, it is said that water leaks from water pipes not only cause cavities, but also, for example, in the case of large municipalities, water leaks in units of 10 billion yen are caused by water leaks.
[0077]
Conventionally, the investigation of the leak location is determined by the sound of the leak. For example, it is said that it takes 5 years for a large municipality to complete a full survey, so if you fail to find a leak location due to an error, you must continue to leak until 5 years after the next survey is performed. become.
[0078]
However, the use of the underground survey system of the present embodiment has the advantage that the number of survey days can be reduced and the survey can be reliably performed.
[0079]
In this case, the radar 210 for investigating a leak location is lent or transferred to, for example, a local government's water bureau and mounted on the patrol car 100 of the water bureau.
[0080]
Since the location of the buried water pipe is known and a leak point can be found simply by traveling on it, finding the leak point in the water pipe is easier than finding a cavity. The location of the geographical leak point is specified by GPS.
[0081]
In addition, a plurality of single-function radars 210 used for exploration of cavities or water leak pipes are provided, and a plurality of functions such as exploration of cavities and water leak pipes are shared, or a radar having multiple functions is used instead. One 210 may be provided. In addition, there is an advantage that handling, maintenance, inspection, storage, and the like of the radar are facilitated by using the radar 210 in common.
[0082]
Further, in the above-described embodiment, the present invention is used for the investigation of the underground of the public road. However, the present invention is not limited to this, and may be used for the underground abnormality detection of the factory site, the test course, the runway and the like. If these cavities occur underground, they may collapse and lead to a major accident.
[0083]
In the above-described embodiment, an organization that repairs a pavement road may be provided in the research organization 20, and the organization may repair an underground abnormality.
[0084]
Further, in an underground investigation system in which an investigation organization that conducts an investigation of an underground pavement provides an investigation result of the underground of the pavement to a pavement manager who manages the pavement, the investigation organization certifies the investigation of the abnormality in the underground. May be performed.
[0085]
According to each of the embodiments described above, since the investigating body, which is an expert, judges whether repairs are required or certifies the investigation, it is clarified that accurate judgment and the necessity of an accurate investigation are necessary. It becomes.
[0086]
