Description

Technical Field

[0001] The invention belongs to the technical field of engineering safety, and in particular relates to a road collapse monitoring and early warning system and an early warning method. Background Art

[0002] Nowadays, the challenges facing road structure safety are becoming increasingly severe, and the risk of sudden collapse disasters is rising. In order to ensure traffic safety and reduce the negative impact on society, it is crucial to realize a reliable and efficient monitoring and early warning system.

[0003] According to statistics, the main factors leading to road collapse include natural compaction and settlement of soil, pipeline leakage, and surface water infiltration. These problems usually originate from changes in groundwater levels or seasonal climate impacts (such as the melting of frozen soil in northern winter in spring). These changes can cause a sharp increase in soil moisture content, thereby destroying the road base structure. In addition, pipeline leakage and surface water infiltration can cause water to penetrate into the road base layer and foundation from the sides and below. After soaking, the soil moisture content increases, the weight increases, and thus compression forms cavities, which eventually cause the road surface to collapse under the action of vehicle dynamic loads.

[0004] In recent years, global climate change has exacerbated changes in precipitation patterns, increasing the risk of road structure damage. Although ground penetrating radar technology has made significant progress, achieving underground three-dimensional structural imaging and providing real-time data in combination with GPS / Beidou navigation, its application scope is still limited by equipment costs and technical limitations. Ground penetrating radar detection results may quickly become invalid, especially in conditions such as heavy rainfall, underground conditions can change significantly in a short period of time, making previous safety assessments meaningless.

[0005] Therefore, in response to the needs of road structure safety, there is an urgent need for a method that can provide long-term effective monitoring and rapid and accurate early warning. Summary of the invention

[0006] The present invention aims at solving the defects in the prior art and provides a road collapse monitoring and early warning system and an early warning method.

[0007] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a road collapse monitoring and early warning system, including an underground part; the underground part includes a collapse measurement box and a collapse measurement cone.

[0008] The collapse measuring box comprises a shell, inside of which an alarm sliding bus pipe and a ring bus trigger are arranged.

[0009] Alarm sliding bus pipe: located inside the collapse measurement box, connected to the network cable and power cable on the top, the pipe is used to carry the ring bus trigger, and the alarm light is turned on by pulling and moving.

[0010] The ring bus trigger is used to touch different parts of the warning light sliding trigger ring, thereby activating the corresponding alarm level.

[0011] Collapse measuring cone: used in conjunction with the collapse measuring box, and one collapse measuring box is connected to at least two collapse measuring cones; each collapse measuring cone is connected to the collapse measuring box through a casing; the collapse measuring cone is located under the collapse measuring box and moves as the soil sinks.

[0012] The collapse measuring cone is connected to a carbon fiber binding wire through a sinker collar at the top, and the binding wire enters the interior of the collapse measuring box and is finally connected to the alarm sliding bus pipe of the collapse measuring box.

[0013] Furthermore, the binding wire is also connected to the network cable distribution plate located in the information terminal box through the corner distribution plate; the network cable distribution plate is used to distribute a bundle of network cables to each monitoring point and ensure that the network cable connector of each monitoring point is firmly bound to the binding wire.

[0014] Under normal circumstances, the binding wire is under appropriate tension and will not cause additional pressure on the network cable connector; at this time, the data of all monitoring points can be transmitted back to the information center through the network cable for real-time monitoring and analysis.

[0015] When the underground soil settles significantly, the collapse measurement cone will sink and pull the binding wire. As the binding wire gradually tightens, greater tension will be applied to the network cable connector. Once the tension of the binding wire exceeds the preset threshold, the network cable connector will be pulled apart, causing the communication between the monitoring point and the information center to be interrupted. This indicates that the underground structure has undergone serious deformation or collapse.

[0016] Furthermore, the collapse measurement box is also equipped with a temperature and humidity measuring instrument and a sedimentation spring to continuously monitor changes in the surrounding environment and upload the data to the information center.

[0017] Among them, the temperature and humidity measuring instrument is used to reflect the real conditions of the soil.

[0018] One end of the settlement spring is fixed to the top or side of the collapse measurement box through a ring to ensure that it can move with the box when the soil settles; the other end of the settlement spring is connected to the collapse measurement cone or binding wire to form a complete mechanical conduction path; the settlement spring is used as a mechanical displacement sensor to measure the vertical displacement of the collapse measurement box relative to the initial position.

[0019] Furthermore, the working process of the settlement spring is as follows: when the collapse measuring cone moves downward due to soil settlement, it pulls the binding wire, thereby causing the settlement spring to be stretched and deformed. At this time, the distance x that the collapse measuring box moves downward can be calculated by measuring the tension F on the spring and the known stiffness coefficient k.

[0020] The upper part of the settlement spring is connected to a sensor in a network cable, which can monitor the change in the tension of the spring in real time and convert it into an electronic signal to send to the information processing system; the system measures the degree of settlement of the base soil based on the displacement of the collapse measurement box.

[0021] Furthermore, the monitoring and early warning system is equipped with a camera to capture on-site conditions.

[0022] Furthermore, the monitoring and early warning system also includes an above-ground part; the above-ground part includes an information terminal box and an alarm projection lamp arranged on a lamp pole, an information processing system is integrated in the information terminal box, and a pulley assembly is also installed in the information terminal box, one end of the pulley assembly is connected to the impact block, and the other end of the pulley assembly extends out of the information terminal box and is connected to the fluorescent banner; the inner cavity of the lamp pole accommodates an early warning impactor, and the early warning impactor is connected to the inner cavity of the lamp pole and below the impact block through a telescopic controller.

[0023] An impact tube is arranged in the inner cavity of the lamp pole and below the early warning impactor. The top of the impact tube is open and contains a sodium azide early warning medicine bag. A bell mouth is opened on one side of the impact tube, and a bell mouth cover is provided on the bell mouth. A folded fluorescent banner is placed in the bell mouth.

[0024] When the collapse measurement box sinks, it will pull the binding wire, eventually causing the network cable to disconnect; after the information processing system in the information terminal box receives this signal, the alarm projection light flashes and projects; at the same time, the telescopic controller retracts the spring after receiving the impact signal, causing the early warning impactor to fall under the action of gravity and hit the sodium azide early warning medicine package, causing a physical change to release a large amount of gas to break open the trumpet cover and push out the folded fluorescent early warning banner; and according to the height of the pole, the time is calculated in advance, and the early warning pressure block is released to cause it to fall and pull the banner up.

[0025] Furthermore, the above-ground part also includes:

[0026] The solar panel is installed on the top of the light pole and connected to the information terminal box through wires.

[0027] Street lights: used to ensure normal lighting of roads at night; street lights are connected to solar panels and information terminal boxes through wires.

[0028] Roadside equipment box: used to accommodate electrical equipment and protect internal components from the external environment. The roadside equipment box is buried under the street light pole or wrapped around the street light pole. The roadside equipment box is made of stainless steel and painted with waterproof and rust-proof paint.

[0029] Furthermore, the monitoring and early warning system also includes a soil detector for further monitoring soil settlement at and below the road base.

[0030] A road collapse monitoring and early warning method, the early warning method is based on a road collapse monitoring and early warning system, and specifically comprises the following steps:

[0031] S101: Continuously monitor surface water infiltration, groundwater level changes and other potential interference factors through soil detectors, temperature sensors, etc.; once abnormal changes are detected, immediately initiate subsequent steps.

[0032] S102: The base or foundation soil is soaked by water, and the soil shrinks downward, resulting in a hollow space.

[0033] S103: The soil detector detects abnormal changes in humidity below, feeds back information data, and issues an early warning. The central processing system determines the consequences of the abnormal changes based on the data and issues feedback information in a timely manner.

[0034] S104: When the system determines that the road base or foundation soil has been severely deformed, the collapse measurement equipment slides down by gravity until the length of the binding wire is exhausted and the network cable is finally broken, triggering the alarm mechanism. This process ensures that emergency response can be initiated even when network communication is interrupted, and the excess space of about 5cm-10cm at the binding wire is reserved to avoid network disconnection caused by construction disturbance.

[0035] S105: Multi-channel early warning, including:

[0036] Visual warning: The node alarm light comes on, and the cameras installed on both sides of the road start recording on-site images, which are then transmitted back to the central processing system in real time via the wireless communication module.

[0037] Sound and light warning: The fluorescent warning banner rises, accompanied by a sound alarm.

[0038] Remote notification: Push notifications via SMS and APP to expand the warning range and send notifications via wireless communication modules.

[0039] S106: The collected information, such as images, videos, sensor data, etc., is transmitted back to the central processing system in real time through the wireless communication module and is simultaneously sent to the traffic management department.

[0040] Compared with the prior art, the present invention has beneficial effects.

[0041] The present invention buries highly sensitive collapse measuring devices (such as measuring boxes and measuring cones) in the road base to monitor soil settlement, temperature and humidity changes in real time, and transmits the data to the information center for analysis. Artificial intelligence technology is used to assess risks in real time. Once an abnormal situation is detected, a multi-channel early warning mechanism is immediately activated, including broadcast notifications, mobile phone text message reminders, navigation APP push notifications, and community alarms, to ensure timely and effective response measures to protect public safety and social stability.

DETAILED DESCRIPTION

[0079] In order to make the purpose, technical scheme and beneficial effects of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0080] like Figure 1-35 As shown, in Example 1, the information terminal box is set on the lamp pole, and the setting height is not less than 3 meters. It includes a pile point information storage processor inside, stores and sends relevant information, and integrates network cable distribution, alarm lights, and solar power supply lines. The box body should be cylindrical, with a set of pulleys inside, connected to the early warning impactor and the impact block, and after receiving the danger signal, the machine and the impact block are released to ensure that the fluorescent banner is smoothly unfolded and raised. On the side close to the road, an alarm projection lamp and a camera are installed.

[0081] The roadside equipment box is buried under the street light pole, and the street light pole can also be wrapped inside. The design dimensions of length, width and height are: length 40-60cm, width 40-60cm, height 50-70cm. It can also refer to the size of the outdoor waterproof distribution box. It can be determined separately according to the width of the roadbed of the road construction and the surrounding environment of the street light pole. The roadside equipment box is made of stainless steel and painted with waterproof and anti-rust paint.

[0082] The on-road equipment box is buried under the road base, with design dimensions of length, width and height: length 40-60cm, width 40-60cm, height 50-70cm. The dimensions can also refer to the dimensions of the outdoor waterproof distribution box, which will be determined separately according to the width of the roadbed for road construction and the surrounding environment of the street light poles. The roadside equipment box is made of stainless steel and painted with waterproof and anti-rust paint.

[0083] The casing pressure relief cover is welded on the top of the casing to disperse the road pressure and protect the casing. The design width is 5cm-10cm, the thickness is 2cm, and it is made of 3-5mm thick galvanized steel plate or cast iron plate.

[0084] The line casing and pipes are made of cast iron and painted with anti-rust paint. The designed nominal diameter is not less than DN40 to ensure that all lines have sufficient space for layout.

[0085] The collapse measurement box is designed to be cylindrical and conical in shape, with a hollow middle part, an overall height of not less than 0.5 meters, and a maximum diameter of not more than 0.5 meters. The design adopts a stainless steel shell, and the non-hollow area is poured with coarse aggregate concrete. The collapse measurement boxes are arranged at intervals of 5-10 meters, and the buried depth is set according to the roadbed and foundation conditions. It can also be arranged in one row in each lane. Since the collapse measurement box is made of hard material and arranged evenly, it can also be used as an auxiliary material to strengthen the bearing capacity of the road base soil, and does not affect the surrounding arrangement of gravel and other materials. The design layout position is about 5cm below the surface of the road base. It adopts a conical shape with a large top and a small bottom, with a design height of not less than 20cm, a design maximum diameter of not less than 20cm, and a design weight of not less than 10kg, so as to ensure that its weight can effectively pull the binding wire, lateral slotting, soil detection and collapse measurement equipment slot position diagram of the collapse measurement equipment line slot effect.

[0086] The alarm sliding bus tube has a ring bus trigger set on the wire tube. According to the movement of pulling, it slides and rubs to contact the upper, middle and lower parts of the sliding trigger ring of the alarm light, and different alarm requirements are issued according to different trigger positions.

[0087] The collapse measuring equipment binding wire is made of carbon fiber. The binding wire is inside the wire tube, enters the measuring box, and is connected to the alarm sliding bus tube through the wire tube shaft.

[0088] The collapse measurement cone has the same shape as the collapse measurement box, a solid design, and is cast with coarse aggregate concrete. Its volume is smaller than the collapse measurement box, with an overall height of not less than 0.3 meters and a diameter of not more than 0.5 meters. A settlement ring is set on the top, and the binding wire is replaced and passed through the casing to connect to the collapse measurement box.

[0089] The cable trough cover of the collapse measuring equipment is made of stainless steel or cast iron. The cable trough cover is used to cover the side cable trough of the collapse measuring equipment to prevent the base soil from entering the cable trough or the construction machinery from rolling the base and affecting the line for monitoring the soil.

[0090] The collapse measuring wire groove is located on the side of the collapse measuring device and is grooved along the side of the collapse measuring device with a depth of 1-2 cm and a width of 2-3 cm.

[0091] The metal embedded rod of the collapse measuring device is embedded in the collapse measuring box, with a collapse measuring device ring on the outside. It is made of stainless steel or cast iron. The diameter of the ring rod is not less than 5mm, and the bending anchor length is not less than 20 times the diameter. It is bent and welded, and its shape is similar to that of an anchor or a steel bar bending anchor.

[0092] The collar of the collapse measuring equipment is made of stainless steel or cast iron. The collar rod diameter is not less than 0.5 cm, and the outer collar diameter is not more than 5 cm, so as to avoid taking up more space and affecting the use of other equipment.

[0093] The line casing is opened with a diameter of about 5cm to ensure that the binding wire or tie inside the casing is effectively connected to the collapse measurement equipment.

[0094] The binding wire of the collapse measurement equipment uses the common carbon fiber wire (rope) on the market, and the basic technical parameters are required: tensile strength greater than or equal to 4900MPA, elongation 1.5±0.02%, diameter 7 microns, linear density 760±20g / cm 3

[0095] The vertical connecting rod of the collapse measuring equipment is made of stainless steel or cast iron. The diameter of the ring rod is not less than 5mm. The vertical rod is inside the collapse measuring equipment and its length is not less than 10cm.

[0096] Sensor wires, conventional wires, two in total, one for power supply and one for information transmission, connected to the lower temperature and humidity measuring instrument and connected to the network cable in the upper casing.

[0097] The design parameters and specific functions of the temperature and humidity measuring instrument can refer to the current agriculture and planting industries, especially the temperature and humidity measuring instruments commonly used in home flower cultivation.

[0098] The lifting ring protection pipe is tightly connected to the upper line casing to prevent the base soil from entering the casing and interfering with the monitoring effect. The casing project diameter and material are consistent with the line casing.

[0099] The settlement pulling effect of the collapse measuring equipment, the road base soil, especially the lower base soil, changes in moisture content, causing the bottom to shrink and present a hollow effect. The collapse measuring equipment continues to slide down due to its own shape and deadweight. At the same time, the binding wire of the collapse measuring equipment is pulled, and the binding wire pulls the network cable connector in the distribution plate. The network cable connector is pulled open, and the information transmitted to the information terminal box on the lamp pole is interrupted. The information processing system in the terminal box automatically starts the disaster warning program.

[0100] The network cable distribution plate is designed to look like a flange connected to a pipe. A bundle of network cables is distributed at the distribution plate, and the network cable connectors are ensured to be connected together with the binding wires of the collapse measurement equipment.

[0101] The network cable connector adopts a round pancake-shaped shell to ensure a certain friction with the distribution plate to avoid construction disturbance. The network cable can be pulled apart. The crystal connector at one end of the network cable in the shell ensures a tight connection with the network cable connector on the opposite side. The clip of the traditional network cable crystal connector is not set or removed during installation to prevent the network cable from not being pulled apart in time when it is under force.

[0102] The network cable connector on the opposite side adopts a round pancake-shaped shell and relies on the crystal connector at one end of the network cable to ensure a tight connection with the 28-network cable connector. The clip of the traditional network cable crystal connector is removed to prevent the network cable from being pulled apart in time when it is under stress.

[0103] The network cable is divided into a bundle of network cables, which are connected to the network cable connectors respectively.

[0104] There is a surplus space of about 5cm-10cm for the binding wires to avoid construction disturbance and natural settlement of the road causing network disconnection, thereby providing an early alarm.

[0105] The wire binding corner roller is designed with a metal shaft, which is connected to the road equipment box or roadside equipment box up and down. The rotor on the shaft is made of smooth ceramic and can rotate flexibly to ensure that the pulling of the wire is not hindered by friction.

[0106] The upper and lower pulleys are made of smooth ceramic, installed in the information terminal box, and threaded with carbon fiber wires. They are used to release the warning impactor and warning pressure block, and raise the banner synchronously.

[0107] The inner core of the information terminal box is made of aluminum alloy and is used to fix the pulley, early warning impactor, early warning pressure block, and connect the circuit. When receiving serious collapse information, the telescopic controller is set to release the early warning impactor for the first time to let it fall. According to the height of the light pole and the reaction and impact reaction below, it is released again after about 1 second to put down the early warning pressure block.

[0108] The early warning impactor is made of solid cast iron and weighs no less than 2kg. A groove is set on the top to facilitate the telescopic controller to get stuck and prevent it from falling. The lower part is in a pointed cone shape to facilitate free fall and impact with the medicine bag.

[0109] The early warning charge is placed in the bottom impact tube, in a soft plastic package, which contains sodium azide (NaN3). When hit, the plastic package explodes, and the high-pressure gas collides with the folded fluorescent banner in the impact tube, hitting the impact tube and the outside of the pole.

[0110] The early warning block is made of solid cast iron and weighs no less than 3kg. After it falls, it presses down the early warning impactor at the bottom, and through its fall, pulls the carbon fiber rope binding line on the pulley downward, and the other side of the rope upward, pulls the tie on the pole, and pulls the banner to a height of about 5 meters.

[0111] The impact cylinder is divided into two parts: a vertical cylinder and a trumpet-shaped mouth. The vertical cylinder is located inside the pole, at a height of not less than 1 meter from the road surface, to prevent rainwater from backflowing and seeping in. A folded fluorescent banner is placed in the trumpet-shaped mouth, and the opening is closed from the inside.

[0112] The early warning impactor, early warning charge, early warning pressure block, impact tube and folded fluorescent banner are all located inside the pole.

[0113] Embodiment 2: Solar panels are used as the system power supply in each pile point area to ensure energy saving and environmental protection to the greatest extent. The solar panels used in common street lamps can be referred to, and the common 6V25W model configuration can be referred to.

[0114] Street lights are common LED street light models and do not require special design, but it is necessary to ensure that the lines are unobstructed, meet regulatory requirements, and have reliable performance.

[0115] The information terminal box is installed on the light pole, with a height of not less than 3 meters. It includes a pile point information storage processor, stores and sends relevant information, and integrates network cable distribution, alarm lights, and solar power lines. The box should be cylindrical in shape, with a set of pulleys installed inside, connecting the early warning impactor and the impact block. After receiving the danger signal, the installation machine and the impact block are released to ensure that the fluorescent banner is smoothly unfolded and raised. On the side close to the road, install the alarm projection lamp and camera.

[0116] The warning projection light is designed to be located on the upper part of the street light pole, at a height of no less than 3 meters from the ground, to ensure that drivers of all types of vehicles can see the effect projected onto the road in the cab at the first time. It is designed as an LED lamp, and the more popular and cost-effective integrated three-color lamp on the market can be used as a reference.

[0117] The camera is a common road camera. It is not turned on normally, but it is turned on when there is an abnormality in the road structure to take pictures of the road traffic conditions between the two stake points.

[0118] The roadside equipment box is buried under the street light pole, and the street light pole can also be wrapped inside. The design dimensions of length, width and height are: length 40-60cm, width 40-60cm, height 50-70cm. It can also refer to the size of the outdoor waterproof distribution box. It can be determined separately according to the width of the roadbed of the road construction and the surrounding environment of the street light pole. The roadside equipment box is made of stainless steel and painted with waterproof and anti-rust paint.

[0119] The on-road equipment box is buried under the road base, with design dimensions of length, width and height: length 40-60cm, width 40-60cm, height 50-70cm. The dimensions can also refer to the dimensions of the outdoor waterproof distribution box, which will be determined separately according to the width of the roadbed for road construction and the surrounding environment of the street light poles. The roadside equipment box is made of stainless steel and painted with waterproof and anti-rust paint.

[0120] The casing pressure relief cover is welded on the top of the casing to disperse the road pressure and protect the casing. The design width is 5cm-10cm, the thickness is 2cm, and it is made of 3-5mm thick galvanized steel plate or cast iron plate.

[0121] The line casing and pipes are made of cast iron and painted with anti-rust paint. The designed nominal diameter is not less than DN40 to ensure that all lines have sufficient space for layout.

[0122] The collapse measurement box is designed to be cylindrical and conical in shape, with a hollow middle part, an overall height of not less than 0.5 meters, and a maximum diameter of not more than 0.5 meters. The design adopts a stainless steel shell, and the non-hollow area is poured with coarse aggregate concrete. The collapse measurement boxes are arranged at intervals of 5-10 meters, and the buried depth is set according to the roadbed and foundation conditions. It can also be arranged in one row in each lane. Since the collapse measurement box is made of hard material and arranged evenly, it can also be used as an auxiliary material to strengthen the bearing capacity of the road base soil, and does not affect the surrounding arrangement of gravel and other materials. The design layout position is about 5cm below the surface of the road base. It adopts a conical shape with a large top and a small bottom, with a design height of not less than 20cm, a design maximum diameter of not less than 20cm, and a design weight of not less than 10kg, so as to ensure that its weight can effectively pull the binding wire, lateral slotting, soil detection and collapse measurement equipment slot position diagram of the collapse measurement equipment line slot effect.

[0123] The alarm sliding bus tube has a ring bus trigger set on the wire tube. According to the movement of pulling, it slides and rubs to contact the upper, middle and lower parts of the sliding trigger ring of the alarm light, and different alarm requirements are issued according to different trigger positions.

[0124] The collapse measuring equipment binding wire is made of carbon fiber. The binding wire is inside the wire tube, enters the measuring box, and is connected to the alarm sliding bus tube through the wire tube shaft.

[0125] The collapse measuring cone has the same shape as the collapse measuring box, solid design, and is cast with coarse aggregate concrete. Its volume is smaller than the collapse measuring box, with an overall height of not less than 0.3 meters and a diameter of not more than 0.5 meters. A settlement collar is set on the top, and the binding wire is replaced, passed through the casing, and connected to the collapse measuring box.

[0126] The cable trough cover of the collapse measuring equipment is made of stainless steel or cast iron. The cable trough cover is used to cover the side cable trough of the collapse measuring equipment to prevent the base soil from entering the cable trough or the construction machinery from rolling the base and affecting the line for monitoring the soil.

[0127] The collapse measurement line groove is located on the side of the collapse measurement device and is grooved along the side of the collapse measurement device with a depth of 1-2 cm and a width of 2-3 cm;

[0128] The metal embedded rod of the collapse measuring device is embedded in the collapse measuring box, with a collapse measuring device ring on the outside. It is made of stainless steel or cast iron. The diameter of the ring rod is not less than 5mm, and the bending anchor length is not less than 20 times the diameter. It is bent and welded, and its shape is similar to that of an anchor or a steel bar bending anchor.

[0129] The collar of the collapse measuring equipment is made of stainless steel or cast iron. The collar rod diameter is not less than 0.5 cm, and the outer collar diameter is not more than 5 cm, so as to avoid taking up more space and affecting the use of other equipment.

[0130] The opening of the line casing is about 5cm in diameter, which is used to ensure that the binding wire or tie inside the casing is effectively connected to the collapse measurement equipment.

[0131] The binding wire of the collapse measurement equipment uses the common carbon fiber wire (rope) on the market, and the basic technical parameters are required: tensile strength greater than or equal to 4900MPA, elongation 1.5±0.02%, diameter 7 microns, linear density 760±20g / cm 3

[0132] The vertical connecting rod of the collapse measuring equipment is made of stainless steel or cast iron. The diameter of the ring rod is not less than 5mm. The vertical rod is inside the collapse measuring equipment and its length is not less than 10cm.

[0133] Sensor wires, conventional wires, two in total, one for power supply and one for information transmission, connected to the lower temperature and humidity measuring instrument and connected to the network cable in the upper casing.

[0134] The design parameters and specific functions of the temperature and humidity measuring instrument can refer to the current agriculture and planting industries, especially the temperature and humidity measuring instruments commonly used in home flower cultivation.

[0135] The settlement spring is firmly connected to the collapse measurement box. With the help of Hooke's law, F = -k × x is derived, and x = -F / k is judged, where: F is the force acting on the object (unit: Newton N) k is the elastic constant or stiffness coefficient (unit: Newton per meter N / m), which reflects the rigidity of the material. The larger the value, the harder the material. x is the deformation of the material, that is, the displacement relative to its equilibrium position (unit: meter m). The negative sign indicates that the direction of the force is opposite to the direction of the displacement, that is, the elastic force always tries to restore the object to its original shape. The upper part of the spring is connected to the sensor in the network cable. According to the tension of the spring, it automatically calculates and judges the downward displacement of the collapse measurement box, thereby measuring the settlement of the base soil.

[0136] The lifting ring protection pipe is tightly connected to the upper line casing to prevent the base soil from entering the casing and interfering with the monitoring effect. The casing project diameter and material are consistent with the line casing.

[0137] The settlement pulling effect of the collapse measuring equipment, the road base soil, especially the lower base soil, changes in moisture content, causing the bottom to shrink and present a hollow effect. The collapse measuring equipment continues to slide down due to its own shape and deadweight. At the same time, the binding wire of the collapse measuring equipment is pulled, and the binding wire pulls the network cable connector in the distribution plate. The network cable connector is pulled open, and the information transmitted to the information terminal box on the lamp pole is interrupted. The information processing system in the terminal box automatically starts the disaster warning program.

[0138] The network cable distribution plate is designed to look like a flange connected to a pipe. A bundle of network cables is distributed at the distribution plate, and the network cable connectors are ensured to be connected together with the binding wires of the collapse measurement equipment.

[0139] The network cable connector adopts a round pancake-shaped shell to ensure a certain friction with the distribution plate to avoid construction disturbance. The network cable can be pulled apart. The crystal connector at one end of the network cable in the shell ensures a tight connection with the network cable connector on the opposite side. The clip of the traditional network cable crystal connector is not set or removed during installation to prevent the network cable from not being pulled apart in time when it is under force.

[0140] The network cable connector on the opposite side adopts a round pancake-shaped shell and relies on the crystal connector at one end of the network cable to ensure a tight connection with the 28-network cable connector. The clip of the traditional network cable crystal connector is removed to prevent the network cable from being pulled apart in time when it is under stress.

[0141] The network cable is divided into a bundle of network cables, which are connected to the network cable connectors respectively.

[0142] There is a surplus space of about 5cm-10cm for the binding wires to avoid construction disturbance and natural settlement of the road causing network disconnection, thereby providing an early alarm.

[0143] The wire binding corner roller is designed with a metal shaft, which is connected to the road equipment box or roadside equipment box up and down. The rotor on the shaft is made of smooth ceramic and can rotate flexibly to ensure that the pulling of the wire is not hindered by friction.

[0144] The upper and lower pulleys are made of smooth ceramic, installed in the information terminal box, and threaded with carbon fiber wires. They are used to release the warning impactor and warning pressure block, and raise the banner synchronously.

[0145] The inner core of the information terminal box is made of aluminum alloy and is used to fix the pulley, early warning impactor, early warning pressure block, and connect the circuit. When receiving serious collapse information, the telescopic controller is set to release the early warning impactor for the first time to let it fall. According to the height of the light pole and the reaction and impact reaction below, it is released again after about 1 second to put down the early warning pressure block.

[0146] The early warning impactor is made of solid cast iron and weighs no less than 2kg. A groove is set on the top to facilitate the telescopic controller to get stuck and prevent it from falling. The lower part is in a pointed cone shape to facilitate free fall and impact with the medicine bag.

[0147] The early warning charge is placed in the bottom impact tube, in a soft plastic package, which contains sodium azide (NaN3). When hit, the plastic package explodes, and the high-pressure gas collides with the folded fluorescent banner in the impact tube, hitting the impact tube and the outside of the pole.

[0148] The early warning block is made of solid cast iron and weighs no less than 3kg. After it falls, it presses down the early warning impactor at the bottom, and through its fall, pulls the carbon fiber rope binding line on the pulley downward, and the other side of the rope upward, pulls the tie on the pole, and pulls the banner to a height of about 5 meters.

[0149] The impact cylinder is divided into two parts: a vertical cylinder and a trumpet-shaped mouth. The vertical cylinder is located inside the pole, at a height of not less than 1 meter from the road surface, to prevent rainwater from backflowing and seeping in. A folded fluorescent banner is placed in the trumpet-shaped mouth, and the opening is closed from the inside.

[0150] The shape of the banner can be set to rectangular or elliptical, with orange fluorescent powder affixed on it, and connected to the closed cover of the trumpet mouth. The gas exploded by the early warning package directly pushes the banner out of the trumpet mouth, and it is unfolded and raised by pulling through the pulley line above.

[0151] The early warning impactor, early warning charge, early warning pressure block, early warning charge and folded fluorescent banner are all located inside the pole.

[0152] Two fiber rope ties can be set according to the specific height of the pole. Ordinary plastic ties are used for tying in a loose-loop direction. The fiber rope will be released under the impact force of the explosive pack exploding below and the pulling force of the pressure block falling above.

[0153] The buried depth of roadside line casing can refer to other electrical pipelines, and it can also be buried in the trench to ensure the reliability of the pipeline. It can use the same material and nominal diameter requirements as the network cable casing.

[0155] The present invention ensures the normal implementation of the collapse warning function under the premise of ensuring normal street lighting. Figure 2 As shown, the location of the information terminal box, street lights, solar panels, etc.

[0156] Set up a warning projection light to project strong light onto the road surface to ensure driving safety at night, especially considering driving on highways at night, so the projection size and distance are set according to different road conditions.

[0157] The collapse warning and measurement equipment shall be buried at the road base or below the road base, such as Figure 3 As shown, the measuring equipment is made of concrete, cast iron, and other materials, which can also ensure that it does not affect the bearing capacity of the roadbed.

[0158] The relationship between the collapse measurement box and the collapse measurement cone is one-to-many, such as Figure 5 As shown, one measuring box corresponds to multiple measuring cones, and the measuring box is partially hollow. The measuring cones are connected inside the measuring box and bundled to the alarm sliding bus pipe, and the alarm projection light is controlled to be turned on by moving the bus pipe up and down.

[0159] A collar is provided above the collapsed measuring box and the measuring cone, such as Figure 6 As shown, the soil pressure is reduced by binding with wires and using casing for protection, and a stainless steel pressure relief cover is used above the casing for protection.

[0160] The warning light sliding bus pipe is located in the local central control area inside the collapse measurement box, such as Figure 7 As shown, the network cable and power cable are connected at the top, and the lines are arranged in the casing.

[0161] The warning light sliding trigger ring is divided into three parts: upper, middle and lower. Figure 8 As shown, the three parts are connected to the overall circuit, and the relevant lines are connected to the warning projection light.

[0162] The carbon fiber binding wire connected to the collapse measuring cone extends into the collapse measuring box, such as Fig. 9 As shown, it is turned through the relevant rotating shaft and enters the wire tube bundle tube to form a wire tube bundle connected to the alarm sliding bus tube.

[0163] Bus trigger, located on the alarm slide bus pipe such as Fig.10 , Fig.11 As shown, by sliding the trigger ring of the warning light during settlement, the specific settlement depth and position can be transmitted back when the trigger ring passes through different areas. If the settlement exceeds the normal range and becomes a collapse, the information will be transmitted back to trigger the alarm projection light, disconnect the network cable, and raise the banner.

[0164] The collapse measurement binding wire is made of carbon fiber rope, and all collapse measurement equipment are equipped with a ring on the top, such as Fig.12 as shown, and arranged through the casing.

[0165] The collapse determination system can also use the real-time data sent back by the soil detector, such as Fig.13As shown, the soil settlement at and below the road base can also be further monitored, including natural and unnatural settlement. And based on the relevant data sent back, it can be judged whether frozen soil or temperature difference changes, excessive humidity, abnormal settlement or even network disconnection problems occur.

[0166] The collapse measuring device comprises a collapse measuring box and a collapse measuring cone, a collapse measuring device vertical connecting rod arranged on the upper part of the structure and arranged inside the collapse measuring device, and a collapse measuring device metal embedding rod.

[0167] Connection ensures that the poured concrete is firmly connected as a whole and does not affect the collapse measurement.

[0168] The collapse measuring device collar can also be connected to a settlement spring, such as Fig.15 As shown, the external ring protection tube is used for firm protection. With the help of Hooke's law, F = -k × x is derived, and x = -F / k is judged, where: F is the force acting on the object (unit: Newton N) k is the elastic constant or stiffness coefficient (unit: Newton per meter N / m), which reflects the deformation displacement. The larger the value, the greater the displacement of the equipment (unit: meter m). The negative sign indicates that the direction of the force is opposite to the direction of the displacement, that is, the elastic force always tries to restore the object to its original shape. The upper part of the spring is connected to the sensor in the network cable, which automatically calculates and judges the downward displacement of the collapse measurement box according to the spring tension, so as to measure the settlement of the base soil.

[0169] The collapse measurement effect is as follows Fig.16 shown.

[0170] If there is a corner in the underground system, a separate on-road equipment box is set up under the road. In principle, the on-road equipment box is not used as much as possible, and the settlement measurement related equipment is directly connected to the roadside equipment box under the street light pole. However, considering the road turns and the regulatory requirements for the layout of road lights, as another preferred solution, the setting location and setting specifications are designed, such as Fig.17 , Fig.18 shown.

[0171] Roadside branch lines are used to connect network equipment. The design can consider that its shape is similar to a flange, and it is a many-to-one or many-to-many interface. The specific design depends on the setting location and takes into account multiple factors such as road traffic related regulations and actual construction requirements. Fig.19 As shown in the figure, the network cable is firmly tied with the carbon fiber binding wire on both sides of the connection plate. According to the tension of the binding wire, it leaves the port of the network cable connection plate to achieve the network disconnection. Fig. 20 , Fig.21 , Fig. 22 As shown, the collapse measuring box is provided with a network cable connection, while the collapse measuring cone is not connected with a network cable.

[0172] When pulling the network cable from the interface, factors such as the vibration of the vehicle above and the natural settlement of the road should be considered. Therefore, a certain amount of excess length should be set according to different regions to ensure accurate use, such as Fig.23 shown.

[0173] The collapse alarm designed by the present invention is based on the situation that the road sinks to a serious degree, that is, the alarm slides to the upper part of the trigger ring, and the network cable is disconnected at the same time, which serves as a double insurance, that is, when the network cable alarm fails, there are still cameras shooting and wires connected, so the alarm light and fluorescent banner can play a role at the same time. Fig.24 , Fig.25 , Fig.26 As shown, a fluorescent banner pop-up alarm system is designed, that is, upper and lower pulleys, an information terminal box core, a warning impactor, and a collision block suspension are arranged in the information terminal box, and the spring of the telescopic controller is electrically controlled, and the spring pops out, clamping the column warning impactor and the collision block. According to the height of the pole, the roadside equipment box can be set on the ground at the bottom, and the impact tube, trumpet, fluorescent warning banner, and impact medicine bag are set in the box. The trumpet is clamped with a metal cover, and the carbon fiber rope is firmly fixed to the outside of the pole with a plastic fiber rope tie on the outside of the pole.

[0174] The signal terminal box of the present invention receives a collapse signal, and the alarm projection lamp flashes and projects. At the same time, the telescopic controller receives an impact signal, retracts the spring, and the early warning impactor falls rapidly under the action of gravity, and hits the sodium azide medicine bag below. The sodium azide undergoes a physical state change rapidly when hit, and releases the gas to open the bell mouth cover, and push out the folded fluorescent banner. According to the height of the wire pole, the opening time is calculated in advance, and the early warning pressure block is released. When the pressure block falls, the banner rushing out of the bell mouth is pulled up according to the pulley principle. Figure 27-Figure 31 shown.

[0175] The present invention provides an early warning procedure, such as Fig.32 As shown, including steps S101-S106:

[0176] S101: Surface water infiltration or abnormal groundwater level, or other disturbances, leading to abnormal changes in road structure.

[0177] S102: The base or foundation soil is soaked by water, and the soil shrinks downward, resulting in a hollow space.

[0178] S103: The soil detector detects abnormal changes in humidity below, feeds back information data, and issues an early warning. The central processing system determines the consequences of the abnormal changes based on the data, and issues feedback information in a timely manner through various channels.

[0179] S104: When the road base or the road foundation soil below the road base is severely deformed, the collapse measuring equipment slides down by gravity, and the excess length of the binding wire is exhausted until the network cable is broken, indicating that the underground has been severely deformed and the network cable is cut.

[0180] S105: The node warning lights at the stake points in front and behind the corresponding areas on both sides of the road light up, and the cameras on the poles on both sides take pictures and videos of the road section in real time.

[0181] S106: Relevant information is promptly transmitted back, and warnings are issued by relevant traffic departments in a timely manner to remind vehicles and pedestrians in relevant areas to pay attention to safety.

[0182] The buried depth of the collapse measuring box of the present invention is set in a targeted manner according to the roadbed and foundation conditions, groundwater level conditions, frozen soil depth, etc., and according to the geological road geological survey report, such as Fig.32 As shown. For example, urban roads can be buried in the foundation below the base, about 1-5 meters from the ground, to ensure that they are arranged near municipal water supply and heating pipelines, focusing on monitoring the leakage of related pipelines and the construction of underground traffic tunnels. In winding mountain roads, or places prone to landslides, mud-rock flows, and low-lying areas with the above potential risks, they are buried below the foundation gravel to ensure that the weight of the gravel increases the sensitivity of the collapse measurement equipment. When excessive surface precipitation infiltrates, it can fall more sensitively and break the network connection to achieve early warning. At the same time, the location of other equipment is flexibly considered. For example, in the above-mentioned areas, the network cable and casing are laid openly on the outside of the metal guardrails on both sides of the road, without setting the upper cover plate, and are fixed to the groove on the outside of the guardrail by welding, binding, etc. If landslide stones, mud-rock flows, etc. hit the guardrail, the network is disconnected in time and an alarm signal is issued.

[0183] like Fig.34 As shown, the collapse warning of the present invention is set according to whether the actual collapse exceeds the defined range. If the collapse range is not exceeded, the alarm sliding bus moves, and the bus contactor touches the middle and lower trigger ring, and the alarm light will not be activated to avoid false alarms and panic. When the range is exceeded, the upper trigger ring is triggered, and at the same time, the network cable of the collapse measurement equipment is cut off, the warning impactor automatically slides down, and the impact block then slides down. The impactor hits the medicine bag, and the sodium azide in the medicine bag is vaporized. The high-pressure gas pushes the folded fluorescent banner out and automatically unfolds. The impact block falls and pulls the carbon fiber rope, which is pulled up to the specified height through the pulley, and the alarm light is on, the road condition is photographed, and the information is transmitted back.

[0184] The information processing function of the present invention is divided in detail, and the design is divided into two aspects, namely normalized monitoring and risk warning. Normalized monitoring is carried out by monitoring the connection network cable and the power supply wire of the solar panel through the temperature and humidity measuring instrument and the settlement spring, and the road structure information between each pile point is especially the frost heave risk of the road in the northern region, the thermal expansion and contraction of the spring frozen soil melting, the roads affected by the urban municipal construction, the tunnel excavation route, the turning connection of the main municipal pipeline, the key sections of the highway affected by seasonal rainfall all year round, the winding mountain road, the highway with the disaster risk warning such as landslide and mudslide, etc. as the key monitoring area of ​​the present invention, the humidity, temperature, settlement and other information of the relevant area are used as the key analysis information, and the normal information monitored is compared by the information terminal processing equipment in the information terminal box, which does not exceed the preset value, and does not need to be returned in real time, and according to the set monitoring time, it can be stored and returned regularly. If the data exceeds the setting, it is automatically determined to be abnormal, and it is immediately returned and analyzed and judged, and the auxiliary hardware alarm light turns red synchronously.

[0185] The innovation of the present invention lies in the use of low-cost materials, innovative network cable breaking, sliding control of the alarm projection light, and physical state change achieved by impacting sodium azide to knock out the fluorescent banner, as well as the pulley principle to raise the banner, etc., to achieve multiple judgment methods and give early warning of road collapse.

[0186] The disaster warning involved in the information processing in the present invention occurs when the humidity is abnormal or the settlement is abnormally severe. The camera on the pole is also designed to start the monitoring function, monitor the real-time situation of the road in real time, and send back information in time. If the road structure collapses, an early warning will be immediately issued through traffic broadcasts, navigation notifications, flashing signal lights, tweeter warnings, etc. The present invention takes the actual situation into consideration. The various functions of the present invention are realized by electricity, and the electricity supply comes from the solar panels on the lamp poles to ensure power supply all day and all time.

[0187] The information sending device mainly sends warning information through traffic broadcasts, navigation notifications, flashing signal lights, tweeters, etc. However, traffic broadcasts and navigation notifications need to be analyzed in detail by information processing, and judged by humans, and approved by relevant departments to send broadcasts and navigation related notifications. The present invention is limited to providing related methods.

[0188] The road structure safety monitoring and early warning process design consists of two parts: routine monitoring and disaster early warning. Among them, routine monitoring uses the soil detector under the collapse measurement equipment to monitor the humidity, temperature, and water content of the base layer or the foundation under the base layer, and analyzes the special abnormal data in the monitoring results to facilitate early detection and timely resolution of problems.

[0189] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, it should be understood by those skilled in the art that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features therein may be replaced by equivalents. Therefore, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope defined by the claims of the present invention.

This process ensures that emergency response can be initiated even if the network communication is interrupted, and the excess space of about 5cm-10cm at the binding wire is reserved to avoid network disconnection caused by construction disturbance; S105: Conduct multi-channel early warning, including: Visual warning: The node warning light lights up, and the cameras installed on both sides of the road start recording on-site images, which are transmitted back to the central processing system in real time through the wireless communication module; Sound and light warning: fluorescent warning banner rises, accompanied by sound alarm; Remote notification: push notifications via SMS and APP to expand the warning range and send notifications via wireless communication modules; S106: The collected information is transmitted back to the central processing system in real time through the wireless communication module, and is simultaneously sent to the traffic management department.
