Description

Collapse forecast warning system and reinforcing method for slope

The present invention is a system for predicting collapse of a slope or a slope of a slope, which monitors the bank of a reservoir or a slope of a mountain at all times to give a warning when there is a possibility of collapse, and to take early action to reinforce the area by taking early action when there is a sign of collapse, and the slope of the slope It's about reinforcement.

On slopes such as incisions or slopes along roadsides, stones or soil fall or landslides occur due to floods or wind damage, which causes unexpected damage to buildings as well as vehicles and people passing by.

In order to prevent landslides or rockfalls, as shown in FIG. 1A , reinforcement facilities are separately constructed and reinforced on slopes such as incisions or slopes, and a photographing device such as a camera is provided at a specific location to photograph the site.

In addition, as shown in FIG. 1b, by installing a displacement sensor such as surface displacement or underground displacement, sensor information and rainfall information are acquired and transmitted to the control server to monitor the collapse risk target area in real time, and a warning message when there is a risk of collapse and a warning sound to prevent damage caused by slope collapse.

In addition, in order to prevent falling rocks, measures to prevent falling rocks are usually installed in the vicinity of the road or in the lower part of the slope.

As a technology related to monitoring of slopes, Patent Publication No. 10-2016-0018191 (Slope Collapse Pre-Detection System), Registered Patent Publication No. 10-0351745 (Slope Collapse Detection Method and Apparatus), Korean Patent Publication No. 10-2009-0056122 ( A slope collapse monitoring system and method) is disclosed, and as a slope reinforcement related technology, Patent Publication No. 10-2010-0029425 (a concrete acupressure plate for reinforcing soil and sand slope using soil nails and a reinforcement method using soil nails) is disclosed. , is disclosed in Utility Model Registered Utility Model Publication No. 20-0405982 (double ridged network structure for preventing rock fall) as a technology for preventing rocks from falling.

However, in the prior art, the technology for monitoring the collapse of the slope using one or more sensors, the technology for reinforcing the slope, and the prevention of rock fall have been developed, respectively. There was no bar.

In other words, there is no technology that monitors slope collapse at all times, and provides immediate response and reinforcement in case of any signs of collapse, as well as effectively blocking the occurrence of falling rocks and checking the presence or absence of falling rocks. .

Therefore, there was a problem of double costs as the facility construction for slope monitoring and the slope reinforcement work for follow-up were separately performed, and the possibility of collapse due to failure to respond immediately in case of signs of collapse is that much. can only rise

In addition, in a state where the possibility of collapse exists, the grouting construction work is performed after drilling a hole in the corresponding slope with a drilling machine, which increases the possibility of a safety accident as well as aggravates the collapse. There was a problem in that the slope reinforcement work had to be performed in the midst of anxiety.

In addition, in the case of a rockfall prevention measure, it is just a combination of rockfall prevention nets, so if a rockfall or silt falls, it is easily damaged by the load transmitted from them. There was a problem with the import. 2A and 2B are photographs showing that the rockfall prevention measures including the rockfall prevention nets are damaged by the falling rocks due to the collapse of the slope.

As described above, it is a situation in which rockfall prevention measures are easily damaged by falling rocks when the slope collapses. Accordingly, technologies for falling rock prevention measures with improved durability are being developed, but they are absolutely safe from falling rocks and soils with a relatively large weight. I couldn't.

At this time, it is preferable that the meteorological observation unit 60 for measuring the weather condition and transmitting the measured weather information to the field controller 50 is installed on the inclined surface.

In addition, at least one of a vibration sensor 45 for detecting vibration and a moisture sensor 46 for detecting moisture is installed in the other buried pipe in which a sound sensor is not installed among the buried pipe 1 .

On the other hand, a rock fall prevention measure 70 is installed on the lower portion of the inclined surface where the temperature sensor 10, the displacement sensor 20 and the sound sensor 40 are installed, and the back surface of the rock fall prevention measure 70 facing the inclined surface is a prevention measure A blocking member 75 is installed to prevent the damage of the rockfall prevention measures by absorbing shocks as well as being fixed to the posts by fixing members.

Hereinafter, a system for predicting collapse of a slope and a method for reinforcing the slope according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 3 to 11, the system for predicting collapse of a slope of the present invention is a technology for constantly monitoring a slope of a bank or a mountain to provide a preliminary warning when there is a possibility of collapse, a temperature sensor 10, Transmitting information detected from the buried material 15 , the displacement sensor 20 , the embedded pipe 30 , the sound sensor 40 , the temperature sensor 10 , the displacement sensor 20 and the sound sensor 40 . It consists of a field controller 50 installed on a part of the inclined surface to receive information, and a management server 55 installed at a remote location to receive sensing information from the field controller 50 .

A plurality of perforation holes 1 are formed in a plurality of positions to be spaced apart from each other on the inclined surface of the slope.

The drilling hole 1 can be used as an installation space for the temperature sensor and the sound sensor, and can be used as a hole for grouting construction for slope reinforcement as a countermeasure when there is a possibility of collapse.

Therefore, for grouting construction for countermeasures, additional hole drilling work is not performed or only a minimum number of holes need be drilled later. And, since the drilling hole has already been formed in advance, it is possible to immediately respond to the slope reinforcement work.

The temperature sensor 10 is installed by being inserted into any one of the plurality of drilling holes 1 , and a plurality of temperature sensors are installed to be spaced apart from each other in order to detect the underground temperature at various points.

Each temperature sensor is connected with an electric wire, and in order to install it in an accurate underground location, it can be installed using a separate means such as a connecting rod.

At this time, the buried material 15 is filled in the inner space of the perforated hole in which the temperature sensor 10 is installed.

As the buried material 15 is filled, each temperature sensor 10 installed to be spaced apart from each other is partitioned by the buried material and does not exist in the same space.

The landfill 15 uses soil such as earth and sand.

Each temperature sensor 10 is partitioned by the buried material 15 so that it does not exist in the same space within the perforation hole, so that the temperature of the corresponding point can be accurately detected, which has higher accuracy when determining whether collapse exists. be able to

That is, in a state in which a plurality of temperature sensors are installed in the internal accommodating space of the perforated hole without filling the buried material 15, a large difference in temperature occurs as the air present in the internal accommodating space of the perforated hole is in communication with each other. In order to solve this problem, since there is a problem in that the measured temperature is not significantly different even if the temperature is measured at different depths, and this inevitably lowers the accuracy in judging whether the slope has collapsed or not. It was intended to be landfilled with landfills.

The displacement sensor 20 is a sensor for detecting the inclination of the inclined surface, and a plurality of displacement sensors are installed to be spaced apart from each other around the point where the temperature sensor 10 is installed. The displacement sensor is basically to measure the displacement of the surface, but may be installed to measure the displacement of the ground.

As an embodiment, the displacement sensor 20 may be provided with a support and installed on the upper side of the support. In addition, when a separate reinforcement structure is installed on an inclined surface, it may be installed on the reinforcement structure.

When a displacement sensor is installed on a support, it is configured as a tilt sensor and it can be confirmed that displacement has occurred through inclination. It is also possible to confirm that displacement has occurred through the presence of ground clearance.

In addition, the embedded pipe 30 may be inserted into one or more other drilling holes in which the temperature sensor is not installed among the plurality of the drilling holes 1 to maintain the hole shape of the drilled state without the drilling hole collapsing.

That is, the embedded pipe 30 is provided to maintain the shape of the hole by supporting and reinforcing the inner wall surface of the drilling hole because the portion where the hole is formed can collapse in a state in which the hole is formed. As it is installed, it not only provides an installation space for the sensors (sound sensor, vibration sensor, moisture sensor) to be described later, but also serves to cover the sensor so that it is not damaged. so that it can be reused or recycled.

In addition, since the perforated hole is formed, the concrete introduced into the embedded pipe during grouting can be filled while moving to a cracked area or gap in the ground through the perforated hole.

The embedded pipe 30 has an outer diameter slightly smaller than the inner diameter of the perforated hole, and is formed to have a length slightly shorter than the depth of the perforated hole. For example, when the perforated hole is 30 m, the embedded pipe is formed to be at least 28.5 m and less than 30 m, which is 95% of the perforated hole.

The buried pipe 30 may be formed without being limited to a circular shape or a square shape, and a plurality of through-holes 31 are formed on the surface of the buried pipe so that the inside and outside can communicate with each other. In this case, the through-hole 31 may be preferably formed in a size such that relatively large gravel or stones are not introduced into the embedded pipe.

The reason for forming the through hole 31 is to guide the water to be introduced into the inside of the buried pipe when there is water in the ground of the slope where the buried pipe is installed, and also from the inside of the buried pipe such as the sound of water flow. This is to enable accurate detection of underground sound.

In order to detect the underground sound, a sound sensor 40 is installed inside one or more of the embedded pipes 30 inserted into the perforated holes.

The sound sensor is a sensor for detecting the underground sound around the drilling hole, such as when water flows in the ground.

The on-site controller 50 is installed in any part such as the upper or lower part of the slope in order to receive information sensed from a plurality of temperature sensors, displacement sensors, and sound sensors, and transmits the sensed information to the management server 55 in a remote location. will send

The field controller can be installed on a pole that is installed to stand on the ground separately.

A camera is installed on the post where the field controller is installed, and the image information captured by this camera is transmitted to the management server 55 together with the detection information of the sensors (temperature sensor, displacement sensor, sound sensor). Through this information, the manager can monitor the possibility of collapse and the presence or absence of collapse, and in the event of a collapse, it is possible to check the condition of the accident site in real time and deal with it quickly.

In addition, a photovoltaic device or a wind power generator including a photovoltaic module may be installed on the post to supply power to the on-site controller and camera, and a warning light may be installed to inform the surrounding area when an accident such as collapse or falling rock occurs.

The warning light may be installed on a post on which the on-site controller is installed, or when a fall prevention measure is installed, it may be installed on the top of the support post of the fall prevention measure.

The management server 55 is a server provided in a remote location, receives a sensor detection signal from the field controller 50, monitors the slope in real time from a remote location, determines whether collapse is possible, and sets the sensor detection information to a preset standard. If it is determined that there is a risk of collapse by comparing the information with the information, the information is provided to the competent authorities such as 119 and the disaster center as well as the surrounding villages to predict/warn that there is a risk of collapse.

On the other hand, a meteorological observation unit 60 is installed on the slope of the slope to measure the weather condition and transmit the measured weather information to the on-site controller 50 . The meteorological observation unit 60 is for observing the weather of the corresponding area, and in addition to the meteorological information of the Korea Meteorological Administration, it is to more accurately monitor the slope by acquiring the weather information of the corresponding area.

Recently, due to climate abnormalities due to global warming, it is necessary to acquire meteorological information of the monitoring target area in addition to the meteorological information from the Korea Meteorological Administration, because torrential downpours occur frequently, such as intensive rain in a specific area.

The meteorological observation unit 60 may be configured as, for example, a rain gauge for measuring the amount of precipitation.

As described above, the embedded pipe 30 is installed in the plurality of perforated holes, and a vibration sensor 45 for vibration detection and a moisture sensor for moisture detection are located inside the other embedded pipes where a sound sensor is not installed among the embedded pipes. It is preferable that at least one of (46) is installed.

The vibration sensor or moisture sensor is intended to be used as information on the possibility of collapse by sensing the vibration of the ground on a slope or detecting the presence or absence of moisture. As the drilling hole for reinforcement is pre-drilled, it is possible to easily secure the installation space for the vibration sensor or moisture sensor. It has the advantage of being reusable or recyclable.

Here, the vibration sensor 45 may be installed in the innermost part of the embedded pipe, and the moisture sensor 46 is installed in a plurality of different underground heights from the innermost inside the embedded pipe 30, and the management The server 55 classifies the moisture sensor into caution, warning, and severe stages according to the detection information for each location to provide a pre-alarm.

On the other hand, in the present invention, the temperature sensor, the displacement sensor, the sound sensor, the vibration sensor, and the moisture sensor are divided into zones, and then it is preferable to provide a unit controller to manage each unit controller.

The reason for doing this is that there is a limit to wiring all the sensors installed in a large area, and even if they are connected wirelessly, a considerable cost is incurred. The controller transmits information by wireless communication connection with the on-site controller so that it can be managed more effectively at a low cost.

And in the present invention, not only the monitoring of the slope, but also reinforcement measures through grouting construction when there is a possibility of collapse. do.

As is known, the rockfall prevention measure 70 is a facility for preventing rockfall from encroaching into the road, and is usually installed vertically on a retaining wall on the side of the road at a predetermined interval and vertically spaced apart from the holding space. It consists of a rock fall prevention net that is coupled to a post to cover it.

At this time, on the rear surface of the rockfall prevention barrier 70 facing the slope, it is fixed to the prevention fence post with a fixing member to prevent falling rocks and vomit as well as absorb shock to prevent damage to the falling rock prevention fence 75. Installed do.

The blocking member 70 is configured to have a structure in which shock is absorbed and a buffer operation is performed. It is composed of an elastic mat (77) provided.

The case 76 is provided to be positioned between the preventive post and the preventive post which are installed adjacently, and the elastic mat 77 has a mattress structure in which a plurality of elastic springs 78 are built-in for the application of elastic force. can be configured as

The fixing member may be composed of a bracket, a bolt, and a nut.

At this time, the elastic mat 77 may use a mattress used as a known bed as it is, and a mattress that has not been commercialized because harmful components such as radon harmful to the human body were detected in the inspection process, or a mattress that has already been commercialized but has been collected due to harmful components. It can also be used sealed.

A separate reinforcing frame may be installed between the guard posts 71 to reinforce the space where the rock fall prevention net 72 is installed.

And, the blocking member 70 is installed so as to be buffered by receiving an elastic force to the preventive post (71). More specifically, the case 76 constituting the blocking member is fixed by the spring fixing means 79 with the elastic spring 78 interposed therebetween by the preventive post 71 to receive the elastic force of the elastic spring.

And when a rockfall or volcanic material collides with a blocking member in a state in which elastic force is applied to one side of the preventive post 71 or the reinforcing frame, the blocking member is moved in the direction of the preventive holding by the pressing force. A distance sensor 73 is installed to deliver it to the 50 .

Since the distance sensor 73 is installed, the on-site controller or management server can determine whether pressure of rockfall or sediment is applied to the blocking member based on the sensing information that detects the distance between the blocking member and the blocking member.

On the other hand, as shown in FIG. 11 , a promotional panel 80 on which a promotional material is attached or a promotional text or picture is printed for promotion may be installed on the front of the rockfall prevention measure.

The publicity panel 80 is installed to be detachably coupled by a fixing means to the preventive support pole 71 . The fixing means may use bolts and nuts to facilitate attachment and detachment of the promotional panel. Of course, in addition to the method of fixing with bolts and nuts, one end of the PR panel can be connected to the preventive post by a hinge shaft, and the other end is provided with a locking means to configure it in an opening and closing manner.

The publicity panel 70 covers the space between the pillars of the preventive measures installed with the fall prevention net along with the publicity function, and blocks the blocking member installed on the rear surface of the fall prevention measures from being exposed to the outside to have a more beautiful appearance. function to do.

Below, the monitoring of the slopes or soft ground of the slopes and the reinforcement process in case of signs of collapse will be described.

A plurality of perforated holes 1 are formed by drilling to a certain depth of a slope or soft ground of a slope to be monitored, and then a plurality of temperature sensors 10 arranged to be spaced apart from each other in any one of the perforated holes. After insertion, the inner space of the drilling hole is filled with the buried material 15 so that each temperature sensor 10 does not exist in the same space and is partitioned from each other by the buried material 15 .

The temperature sensor 10 is inserted so as to be arranged in a line inside the drilling hole in order to sense the underground temperature of various points.

In the vicinity of the point where the temperature sensor 10 is installed, a plurality of displacement sensors 20 are installed to be spaced apart from each other in order to detect displacement such as the inclination of the inclined surface.

Then, after preparing an embedded tube 30 having an outer diameter smaller than the inner diameter of the perforated hole 1, a plurality of through holes 31 are formed on the surface of the embedded tube, and then the temperature sensor 10 is not installed. Insert it into the drilled hole.

After installing at least one of the sound sensor 40, the vibration sensor 45, or the moisture sensor 46 inside one or more of the embedded pipe 1 inserted into the inside of the perforation hole, the entrance of the embedded pipe 1 and close the inlets of all the remaining embedded pipes (1) so that foreign substances do not flow in.

A field controller 50 is installed on one side of the slope to receive detection information of the sensors (temperature sensor, displacement sensor, sound sensor, vibration sensor, moisture sensor), and a photographing device such as a camera is provided to view the surroundings. The captured image information is received and transmitted to the remote management server 55 together with the detection information.

The management server 55 receives the detection information and image information received from the on-site controller 50 and monitors it at all times, compares the received detection information with the set reference information to determine whether there is a risk of collapse, and shows signs of collapse. However, if it is judged that there is a risk of collapse, the competent authority and surrounding villages are warned of the risk of collapse.

At this time, if there is a risk of collapse, grouting construction is performed to reinforce the slope. After collecting the sound sensor, vibration sensor, and moisture sensor, the concrete is introduced into the inner receiving space of the remaining empty buried pipe as well as the buried pipe where the sensors are collected and grouting is done.

In the present invention, when there is a risk of collapsing, the hole for grouting is not formed later to reinforce the slope, but the hole is drilled in advance and then the hole is used as an installation space for various types of sensors. There is no need to form a mechanism or space for the construction, and as the sensors are installed inside the hole, it is possible to accurately detect the underground information, so that it is possible to more accurately determine the risk of collapse.
