[0017] The utility model will be further described in detail in combination with the drawings and specific embodiments.

[0018] The utility model discloses an embedded airport runway water film thickness sensor fixing tool, which comprises a base 2, a water film thickness sensor 3, an airport runway embedded pipe 5 and a waterproof protection structure.

[0019] The base 2 is embedded in the airport runway 1, and the top surface of the base 2 is flush with the surface of the runway 1. In the embodiment, the shape of the base 2 can be designed as a circle or a square, which is adapted to the surface form of the airport runway and has good compression resistance and wear resistance. The base 2 is made of high-strength alloy material, which has the characteristics of corrosion resistance and fatigue resistance, so as to ensure that the base 2 can maintain good performance in the long-term high-strength use environment of the airport runway. The base 2 is internally provided with a mounting groove, which is customized according to the specifications of the water film thickness sensor, so as to ensure that the sensor can be stably installed in the groove and always maintain a horizontal state. When installing,

[0020] The water film thickness sensor 3 is embedded in the mounting groove, so as to ensure that the top of the sensor is flush with the runway surface. After installation, the base is fixed by the locking device. In the embodiment, the locking device can adopt threaded connection, so that the fixing tool can maintain stability in the long-term high-frequency use of the runway and avoid loosening due to external force or vibration.

[0021] The airport runway embedded pipe 5 is internally provided with a signal cable 4. The output end of the signal cable 4 is led to the signal acquisition equipment area outside the runway along the embedded airport runway protection pipe 5. The water film thickness sensor 3 is connected with the input end of the signal cable 4, and the output end of the signal cable 4 is connected with the signal acquisition equipment 6 arranged in the signal acquisition equipment area.

[0022] The waterproof protection structure comprises a sealing ring, a protective cover and a waterproof coating. The sealing ring is installed between the base 2 and the runway surface, and the protective cover covers the sensor from above. The protective cover is made of transparent high-strength material, which not only protects the sensor from external impact, but also ensures the barrier-free signal acquisition. The waterproof coating is used to cover the outer surface of the base, so as to ensure that the sensor is not affected by external factors such as water and dust.

[0023] The installation steps of the embedded airport runway water film thickness sensor fixing tool are as follows:

[0024] 1. Measurement and positioning

[0025] High-precision measuring equipment is used, and the position of the embedded point is marked according to the design requirements. In this process, it is necessary to ensure that the embedded point and the runway center line meet the relevant specifications, so as to meet the monitoring requirements.

[0026] 2. Pre-embedded protection pipe

[0027] After the completion of the measurement positioning, the airport runway embedded pipe 5 is embedded in the installation hole for the laying and protection of the sensor signal cable 4, one end of which is used for interfacing with the water film thickness sensor 3, and the other end is used for connecting to the signal acquisition device 6. The airport runway embedded pipe 5 is made of corrosion-resistant and waterproof material, which can adapt to the complex runway environment and avoid line damage caused by rain or temperature changes, thereby ensuring the safe transmission of signals.

[0028] 3. Pavement paving

[0029] After the completion of the airport runway embedded pipe 5, the same material as the runway is used to restore the paving surface. The pavement paving needs to ensure the compactness of the paving material and the flatness of the surface to ensure that the runway meets the airworthiness requirements. During the paving process, the interface of the embedded protection pipe should be sealed as necessary to prevent foreign matter from entering the protection pipe during construction and affecting subsequent line laying.

[0030] 4. Re-measurement positioning

[0031] After the completion of the pavement paving, the sensor installation point is rechecked using precise measurement tools to ensure that the re-measured position is completely consistent with the initial design, and the opening of the embedded protection pipe is checked for completeness. If position or size deviation is found, it should be adjusted in time to avoid affecting the subsequent installation and performance of the sensor.

[0032] 5. Drilling and coring

[0033] According to the installation position determined by re-measurement, the runway is drilled using drilling equipment, and the core sample is taken out. The drilling diameter needs to be accurately matched with the size of the base, and the drilling depth needs to be determined according to the height of the base to ensure that the top of the base is flush with the runway pavement after placement. After drilling is completed, special tools should be used to clean the hole, thoroughly remove debris, dust and foreign matter, and ensure that the hole is smooth and clean to provide a good foundation for subsequent base installation.

[0034] 6. Installing the sensor

[0035] After drilling is completed, the base is placed in the drilled hole, its horizontal state is adjusted to make its top flush with the runway surface, and the base is fixed in the hole using a locking device. Then, the water film thickness sensor 3 is embedded in the sensor installation slot inside the base 2, and the signal line of the water film thickness sensor 3 is led into the embedded protection pipe through the slot wire channel.

[0036] 7. Laying the cable

[0037] After the installation of the water film thickness sensor 3 is completed, the signal cable is laid, and the cable is guided along the embedded protection pipe to the signal collection equipment area outside the runway. During the laying process, it is necessary to ensure that the line is smooth, without bending or stress points, and to seal the interfaces of the cable to prevent damage or interference from the external environment.

[0038] 8. Backfilling of the pit

[0039] After installation, the pit around the drill hole and the pre-embedded pipe of the airport runway is backfilled. The backfilling material needs to be consistent with the runway, and the compaction treatment needs to be carried out according to the construction standard to ensure that the runway surface returns to its original appearance. After backfilling is completed, the entire construction area should be cleaned, and whether there are depressions or loose points should be checked, and if necessary, secondary compaction treatment should be carried out to ensure that the runway surface is completely flat.
