Description

Technical Field

[0001] The utility model relates to the technical field of airport runway detection devices, in particular to an airport runway pavement settlement detection device. Background Technique

[0002] An airport runway refers to an extremely long strip area within an airport used to supply takeoff or landing for aircraft. Its material can be asphalt or concrete, or a flattened grass, soil or gravel ground, or even a water surface. It can even be paved with wood boards, shale, coral polyps, clay, etc. Runways are mostly commonly based on land globally. Due to urban planning needs, more and more airport runways need to be formed through reclamation from the sea, cutting mountains and filling valleys, and soft soil foundations. Airport runways all face problems such as settlement amount during operation, differential settlement, and runway cracking.

[0003] However, it still has some disadvantages. For example, multiple settlement monitoring points and settlement base points are set in traditional airport runways. Magnetostrictive liquid differential static level gauges are buried in the monitoring points and settlement base points, and the airport pavement is monitored by collecting data from the magnetostrictive liquid differential static level gauges. This monitoring system layout is complex, has high requirements for equipment accuracy, is troublesome to install and arrange, and has a high cost.

[0004] To solve the above problems, an airport runway pavement settlement detection device is proposed in this application. Summary of the Invention

The connection lines one are arranged along the extending direction of the airport runway, the connection lines two are arranged along the width direction of the airport runway, the connection lines one and the connection lines two are perpendicular to each other, the connection lines one and the connection lines two form a grid structure on the leveling layer, and the intersections of the connection lines one and the connection lines two are connected to each other;

[0007] The connecting groove is provided with a cover plate, and the cover plate is provided with settlement detection components corresponding to the connecting lines at intervals, and the settlement detection components include a sleeve, a pressure sensor, a detector, a movable block, a pull rod and a spring. The center of the bottom of the sleeve is provided with a hole, and the pull rod, the spring, the pressure sensor and the movable block are all located in the sleeve, and the two ends of the spring are respectively fixed to the bottom of the sleeve and the bottom of the movable block. The spring is sleeved on the pull rod, and the upper end of the pull rod is fixed to the bottom of the movable block, and the lower end has a gap with the bottom of the sleeve. The top of the sleeve is provided with a fixed block, and the pressure sensor is fixed to the bottom of the fixed block. The detector is fixed to the outside of the sleeve, and the pressure sensor is electrically connected to the detector;

[0008] Each of the settlement detection components corresponds to a guide unit, and the guide unit includes a positioning block, two opposite side plates, a connecting rod and a guide wheel. The positioning block is fixed on the leveling layer at a position close to the settlement detection component, the side plate is fixed on the positioning block, and the two ends of the connecting rod are respectively fixed on the side plates. The guide wheel is rotatably connected to the middle part of the connecting rod, and the connecting line bypasses the guide wheel, passes through the hole at the bottom of the sleeve, and is connected to the lower end of the pull rod.

[0009] Optionally, the leveling layer further has connection line three corresponding to the connection line one, and the connection line three is fixed on the outer wall of the connection groove and hooked with the connection line one.

[0010] Optionally, a pre-buried pipe for housing the connecting line 1 is pre-buried on the leveling layer.

[0011] The advantages and positive effects of the utility model are as follows: the utility model provides a runway pavement settlement detection component. When the airport runway pavement has settlement, differential settlement, runway cracking and other problems, the connecting line 1 laid on the leveling layer will be pulled. Under the pulling of the connecting line 1, the movable block and the pull rod at one end of the connecting line 1 will move downward. At this time, the pressure sensor will not sense the pressure, and the information will be transmitted to the detector. Therefore, the tension of each connecting line 1 is monitored by the pressure sensor to effectively realize real-time monitoring of the pavement settlement, and the position of the specific pavement settlement is judged by the tension value of the pressure sensor, thereby improving the convenience during road maintenance, further ensuring the safety of the airport runway, and the settlement detection device is convenient and quick to install.
