the drill holes should be slightly inclined towards the hole openings, so that the influence of accumulated water in the hole on the measurement result is prevented.
The connection structure of the micro-pressure sensor and the liquid pipeline is as follows: a T-shaped tee joint is connected in series on a liquid pipeline, a diaphragm of a micro-pressure sensor extends into the pipeline, a body of the micro-pressure sensor is screwed on a vertical pipe of the tee joint, the diaphragm for the sensor is directly contacted with liquid in the pipeline, and a liquid pressure value at the point is sensed and output to a lead through a signal.
The diameter of the drilling hole meets the requirements of filling a liquid pipeline, a T-shaped tee joint, a micro-pressure sensor and a lead.
The micro-pressure sensor is a high-precision and small-range liquid pressure sensor, such as a diffused silicon pressure transmitter. The sensor is required to be in a threaded interface form, and the measuring range of the sensor is determined according to the difference between the liquid level of the liquid reservoir and the lowest point of the pipeline. The height is generally less than 2m, so the range is 0-30 KPa. The output signal of the sensor is in a standard form of 4-20 mA.
The pressure sensor acquisition instrument adopts a universal 4-20 mA multichannel data acquisition system, and data is sent to the host computer through wireless transmission. The number of channels of the acquisition instrument corresponds to the number of sensors.
The method for monitoring the sedimentation deformation of the drilling hole by using the monitoring system comprises the following steps:

And then the liquid pipeline with the micro-pressure sensors is pushed into a borehole, the micro-pressure sensors of the datum point are arranged at relatively fixed positions as reference points, the rest micro-pressure sensors are just positioned on preset measuring points, and the signal output ends of all the micro-pressure sensors are led out and connected to corresponding ports of a data acquisition instrument outside the borehole through wires.
And a second step of: after the whole system is installed and fixed, anti-freezing liquid is injected into the liquid pipeline from the liquid reservoir, and pressure is applied to the liquid pipeline by utilizing the liquid level difference between the liquid reservoir and the liquid pipeline; in order to fill the pipeline with liquid, a thin pipe can be penetrated into the liquid pipeline in advance to the inner end of the pipeline so as to discharge gas when the liquid is injected, and the liquid is pulled out after the liquid is injected;
and a third step of: monitoring rock mass drilling deformation, specifically including:
step 3.1: firstly, collecting reference points and initial pressure values of all the reference points
Let the initial pressure value of the datum point be H 0 0 ；
Starting from the orifice, respectively a first measuring point, a second measuring point and a third measuring point, and the like until an nth measuring point, wherein the initial pressure values of the measuring points are respectively H 0 1 、H 0 2 、H 0 3 、……H 0 n ；
Step 3.2, collecting the datum point after the settlement deformation of the rock mass and the pressure value of each datum point
The pressure values of the datum point and each measuring point which are acquired after the settlement deformation of the rock mass around the drilling hole is subjected to t days are respectively H t 0 、H t 1 、H t 2 、H t 3 、……H t n The settlement of the i-th measuring point can be calculated according to the following formula:
wherein:
0.1 represents a pressure of 1mm water column in Pa/mm;
-settlement of surrounding rock mass, mm, after t days at the ith station;
the pressure in Pa in the liquid tube collected after t days at the ith measurement point.
The invention has the positive effects that: according to the invention, the borehole is deformed and apparent through the liquid level difference between the liquid pipeline and the liquid reservoir, after the borehole is deformed, the measuring point position of the liquid pipeline in the borehole is raised or lowered, the liquid level difference between the liquid pipeline and the liquid reservoir is changed, and the pressure generated by the liquid level difference directly acts on the micro pressure sensor. The pressure value of each measuring point after deformation is measured by a micro pressure sensor, and then the settlement of each measuring point is obtained by the pressure values before and after drilling denaturation. The invention has the advantages of wide adaptability, simple structure, convenient implementation, low cost and stable and reliable measurement data, and provides a way for monitoring the deformation of geotechnical engineering.

The method for monitoring borehole settlement deformation using the monitoring system of the present invention will be described below according to an example of application.
The slope height of a certain strip mine is 170m, and the comprehensive slope angle is 51 degrees. The side slope rock mass has complex structure and partial crushing instability. In order to ensure the safe production of mines, the mining side can monitor the displacement of the slope surface 13 by adopting a method combining a GPS system and optical measurement, and the drilling settlement displacement monitoring method is adopted to master the deformation dynamics of the inside of the slope rock. In implementation, two groups of drilling sedimentation deformation monitoring systems 15 are arranged on the same section, each group of drilling length is 28m, and 12 measuring points are distributed. Since the rock mass at the deep part of the side slope is not deformed, the measuring points at the bottom of the drill hole are set as reference points, and the serial numbers of the measuring points from the bottom of the hole to the hole are sequentially 1, 2 and 3 … …. The measuring point adopts a high-precision diffusion silicon miniature pressure sensor, the measuring range is 0-30 KPa, the comprehensive precision is 0.25% FS, and the long-term stability is 0.1% FS. The data are collected by a secondary instrument arranged at the orifice and converted into wireless signal transmission, and are received, processed and stored by a mine dispatching room.
The two groups of monitoring systems are installed, and initial data acquisition is carried out, and the data acquisition is carried out once a day. Table I and Table II are monitoring results of two sets of detection systems 60 days after installation. It can be seen from the table that the overall deformation of the side slope is small, in the normal range, the deformation in the interior of the side slope rock mass is stable and continuous, and the deformation discontinuity phenomenon does not occur around the predicted slip surface 14 as shown in fig. 3, so that it can be seen that the side slope is in an overall stable state.
