Background

Landslide geological disasters are dangerous in natural disasters, have high occurrence frequency, wide damage range and strong harmfulness, and can cause a great amount of casualties and huge economic losses every year. The landslide monitoring equipment is developed, so that the landslide prediction and early warning are realized, the loss caused by landslide can be reduced to the minimum, and the landslide monitoring equipment is an important measure for dealing with landslide geological disasters.

The deep geological parameter information of the landslide is obtained except for deep deformation and seepage, due to the lack of monitoring instruments, the monitoring content is limited, and the monitoring data are low in coupling. The deformation damage of the landslide is a space-time dynamic evolution process, and the evolution stage and the evolution mode of the process are highly correlated and are accompanied by the characteristic of multi-field coupling. The "one hole multiple test" technique has since been proposed and has been gradually valued by engineering geologists in recent years. By arranging the integrated sensor in the slide body drill hole under the in-situ condition, the accurate measurement of parameters such as pore water pressure, water content and the like under the in-situ condition is realized, and the problems of low efficiency, high cost, poor correlation degree and the like existing in the conventional multi-instrument independent distributed integrated monitoring method are effectively solved. Therefore, based on the thought of 'one hole and multiple measurements', it is of great significance to develop a device for arranging underground multi-parameter monitoring sensors in an in-situ environment and further realize monitoring of underground multi-information parameters.

S3, the driving mechanism 31 is used to drive the pushing body to move toward the pushing groove 23, so that the pushing body 21 and the flexible body 22 are pushed into the drilling hole 400 through the mounting hole 11. Specifically, the control module 41 controls the step motor in the layout probe 3 to work through the integrated circuit board 38, and the step motor is powered on to rotate, so as to drive the transmission gear 31c to rotate, and further the bending chain 31b passes through the through hole 33a and is sent out of the extension box 33. Because the bending limiting sheets 35 enable the bending chains 31b to be bent only on one side, the tops of the two bending chains 31b are fixed in the jacking grooves 23 through the pushing parts 32 and matched with the side walls of the jacking drilling holes 400, and the flexible bodies 22 and the various integrated sensors 24 carried by the flexible bodies are sent into the hole outer sliding body environment for monitoring. During the jacking process, the winding hub 8 rotates so that the reserved cable 9 is always connected to the various integrated sensors 24.

S4, and circulating operation steps S2-S3.

S5, after the arrangement of all the integrated probes 2 of the sensor is completed, the upper end of the sleeve 1 is covered by the sealing cover 15, and the main flat cable 13 is connected with the monitoring system 300 through the flat cable interface 14 on the sleeve 1.

Compared with the prior art, the technical scheme provided by the invention has the advantages of simple operation and high automation degree. The static force jacking mode reduces the disturbance of the monitoring environment, and meanwhile, the method increases the range of the arrangement outside the hole through the unidirectional bending chain 31b type arrangement method, so that the method can be better close to the original underground environment and more accurate landslide underground multi-field information can be measured. By integrating the power-on and communication cables on the outer side of the side wall of the sleeve 1 and connecting the power-on and communication cables with the multiple integrated sensors 24, the ground monitoring system 300 is connected, and is high in reliability and not easy to damage.
