It is often used for transportation, such as the travel of cars and trains, or for water supply, gas supply, and electricity transmission. It is necessary to consider multiple factors such as geological conditions, ventilation, and drainage. Tunnel construction refers to the process of digging and building a tunnel underground or in a mountain. It is necessary to conduct geological surveys of the construction area to understand the properties of the soil and rock, the groundwater level, etc., and then design the tunnel and evaluate the impact of tunnel construction on the surrounding environment. During the construction process, it is necessary to monitor the stability of the tunnel construction to ensure construction safety and long-term structural stability of the tunnel.

By setting a lower-layer sampling and detection mechanism, it can automatically perform sampling and detection after landing. Through the setting of the above-mentioned mechanism, sampling and detection of three positions in the middle layer, high layer and lower layer of the tunnel can be realized, the detection range is improved, and multiple vacuum cylinders can sample gases in different directions.

[0028] A dynamic tunnel construction stability monitoring method uses the above-mentioned dynamic tunnel construction stability monitoring device, including: equipment layout: through the layout method, at least two target points are selected in the tunnel as layout points, and the base component 1, the first rotating component 2, the support component 3, the mobile component 4, the monitoring component 5, the battery component 6 and the second rotating component 7 are arranged based on the layout points to obtain a monitoring point set, and the monitoring point set includes at least two monitoring points, and monitoring data are obtained respectively to obtain a monitoring data set; data judgment: setting a judgment threshold, judging the monitoring data set based on the judgment threshold, when the monitoring data of the monitoring point in the monitoring data set exceeds the judgment threshold, the monitoring points other than the target monitoring points are mobilized as response points through the mobilization method, and the target monitoring points are assisted to jointly obtain monitoring data, so as to improve the accuracy of data monitoring; collaborative adjustment: through The adjustment method adjusts the monitoring component 5 to improve the targeted acquisition of monitoring data; the mobilization method includes: step one: range determination, taking the target monitoring point as the initial point, setting the acquisition range, obtaining the number of monitoring points within the acquisition range based on the target monitoring point and the acquisition range, and obtaining the demand monitoring point set; step two: demand determination, setting the demand threshold, screening the demand monitoring point set based on the demand threshold, and obtaining the screened demand set; step three: direction determination, based on the positional relationship between the screened demand set and the target monitoring point, determining the adjustment direction of the demand point in the demand point set, and obtaining the adjustment direction set, the adjustment direction set corresponds to the screened demand set respectively; step four: position adjustment, the screened demand set is based on the adjustment direction set, and the direction and position of the monitoring point as the demand point are adjusted respectively, to obtain multiple response points, to assist the target monitoring point in jointly obtaining monitoring data.

[0029] It should be noted that multiple points are selected as layout points in the tunnel, and equipment is arranged at the layout points respectively. The equipment is composed of a base component 1, a first rotating component 2, a supporting component 3, a moving component 4, a monitoring component 5, a battery component 6 and a second rotating component 7 as a whole, as a complete monitoring point, which is used for data monitoring. Since the temperature sensor 502 constituting the monitoring component 5 can be used to monitor the temperature data in the tunnel, the laser sensor 503 and the high-definition camera 506 can be used to monitor the deformation in the tunnel, and the humidity sensor 505 can be used to monitor the humidity data in the tunnel, the judgment threshold is set as the limit fluctuation range of the temperature, humidity and deformation data, which are set as: temperature is 40°C, humidity is 85%, and deformation is 50mm. When the data in the tunnel exceeds the set limit fluctuation range, the equipment in the remaining monitoring points is mobilized to assist in monitoring the monitoring points exceeding the limit fluctuation range. The acquisition range is set as a circular area with a radius of 100m. The set demand threshold is the quantity threshold, which is set to 2, that is, when it is necessary to assist in monitoring the target monitoring point, two monitoring points can be mobilized for assisting monitoring.

[0030] like Figure 8-Figure 9 As shown, in the specific implementation process, four points are selected in a tunnel as layout points, which are arranged in a straight line. A base component 1, a first rotating component 2, a supporting component 3, a mobile component 4, a monitoring component 5, a battery component 6 and a second rotating component 7 are respectively set up to form monitoring points, which are respectively set as monitoring points No. 1, 2, 3, and 4, and the intervals are all 50m. When the monitoring data obtained by monitoring point No. 2 exceeds the judgment threshold, the monitoring points within the acquisition range of monitoring point No. 2 are No. 1, 3, and 4. According to the set demand threshold, two monitoring points are selected as screening demand points to form a screening demand set, namely, a combination of 1 and 3, a combination of 1 and 4, and a combination of 3 and 4. The positional relationship between each combination and monitoring point No. 2 is determined, the adjustment direction of each combination is determined, and the first rotating component 2 and the mobile component 4 of each combination are adjusted to realize the position adjustment of the monitoring component 5 to assist monitoring point No. 2 in jointly obtaining monitoring data.

[0031] The method for obtaining the screening demand set includes: S1: monitoring point sorting, obtaining the distance data between the demand monitoring point set and the target monitoring point, obtaining the demand distance set, sorting the demand distance set, and obtaining the distance sorting set; S2: demand screening, based on the demand threshold and the distance sorting set, selecting the priority demand monitoring point in the distance sorting set corresponding to the demand threshold, and obtaining the screening demand set.

[0032] like Fig.10 As shown, it should be noted that, according to the distance data between the demand monitoring point and the target monitoring point, the demand monitoring point with the closest distance matching the demand threshold is selected as the screening demand point to form a screening demand set.

[0034] It should be noted that the positional connection line is determined based on the positional relationship between the screening demand points and the target monitoring points according to the screening demand concentration, and the positional connection line is used as the adjustment direction of the screening demand points.

[0035] In the specific implementation process, three points are selected in a tunnel as layout points, which are arranged in a straight line in the horizontal direction and are set up to form monitoring points. They are set as monitoring points No. 1, 2, and 3 respectively. When monitoring point No. 2 is used as the target monitoring point, monitoring points No. 1 and 3 are used as screening demand points. Since monitoring points No. 1, 2, and 3 are arranged in a straight line in the horizontal direction, the position line connecting the screening demand point and the target monitoring point is a straight line in the horizontal direction. The position line is used as the adjustment direction of monitoring points No. 1 and 3.

[0036] The layout method includes: acquiring the length data of the target tunnel to obtain the target length item, setting a division threshold, dividing the target length item based on the division threshold to obtain multiple target division items, and selecting target points as layout points based on the target division items.

[0037] It should be noted that the division threshold is a set threshold. Based on the working properties of the temperature sensor 502, the laser sensor 503, the high-definition camera 506 and the humidity sensor 505, the division threshold is set to 50m. The target length item is divided based on the division threshold, and the target point is the division point, thereby obtaining the layout point.

[0038] The adjustment method includes: taking the target monitoring point as the benchmark point, obtaining the distance data between each monitoring device in the monitoring unit as the response point and the benchmark point, obtaining the benchmark distance item, obtaining the monitoring data exceeding the judgment threshold in the target monitoring point, obtaining the benchmark data item, and based on the benchmark data item, adjusting the benchmark distance item corresponding to the benchmark data item so that the benchmark distance item is in the shortest state, thereby completing the adjustment of the monitoring component 5.

[0039] like Figure 11-Figure 12As shown, it should be noted that the monitoring data exceeding the judgment threshold in the target monitoring point may be one or more types, namely the temperature monitored by the temperature sensor 502, the deformation data monitored by the laser sensor 503 and the high-definition camera 506, and the humidity data detected by the humidity sensor 505. The directions of the temperature sensor 502, the laser sensor 503, the high-definition camera 506 and the humidity sensor 505 in the response point are adjusted according to the monitoring data exceeding the judgment threshold, so as to realize targeted auxiliary monitoring of the monitoring data exceeding the judgment threshold.
