Embodiment Construction

[0025] The following combined examples and attached figure 1 , 2 The present invention is described in detail:

[0026] like figure 1 , 2 As shown, the airbag tube 1 tail end is provided with an inflatable tube 2, the material used is rubber, the diameter of the airbag tube 1 is 30mm, the length is 126mm, and the inflatable tube 2 has a diameter of 4mm and a length of 3.5m.

[0027] The above-mentioned sensor 3 is provided with a threaded hole 5 at the head, and a cable 6 is connected at the tail. Sensor 3 is 126mm long and 32mm in diameter.

[0028] The bolt 4 is 40mm long, and the diameter of the circumscribed circle of the threaded part is 4mm, matching with the threaded hole 5 on the head of the sensor 3 .

[0029] After the above-mentioned bolt 4 is screwed into the threaded hole 5 of the head of the sensor 3, the above-mentioned airbag tube 1 is set on the sensor 3, and the assembly of the installation device for the microseismic monitoring sensor 3 based on the air...

Abstract

The invention discloses a gasbag-based micro vibration monitoring sensor mounting device and method, and belongs to the field of rock engineering. The device comprises a gasbag cylinder, a sensor anda bolt; a gas tube is arranged at the tail end of the gasbag cylinder; a threaded hole is formed in the head part of the sensor; the tail part of the sensor is connected with a cable and is placed inthe gasbag cylinder; and the bolt is arranged at the head part of the sensor. The method comprises the steps of: firstly, feeding the gasbag-based micro vibration monitoring sensor mounting device tothe bottom of a drilled hole by using a mounting rod; secondly, connecting an inflator with the gas tube, inflating gas into a gasbag until the gasbag cylinder expands to tightly press the hole wall and fix the device, taking off the gas tube, and closing the gas tube to complete the mounting of a sensor; and finally, opening the gas tube to release the gas in the gasbag cylinder, and taking out the device to complete the dismounting. The device is simple in structural form and convenient and rapid to mount and dismount, and is capable of reducing the interference, to micro vibration monitoring, of external construction and protecting the sensors from damage; and a using method of the device is simple to operate, high in working efficiency, time-saving, labor-saving and low in cost.

Description

technical field [0001] The invention relates to an airbag-based microseismic monitoring sensor installation device and installation method, belonging to the field of rock engineering. Background technique [0002] In the tunnel TBM construction face, the advancing speed of the working face is fast, so in order to better receive the signal near the working face, it is necessary to continuously move the sensor. The traditional method of drilling sensors to install them is costly and difficult to operate, which can easily cause damage to the sensors or make them impossible to recycle. [0003] Therefore, an airbag-based microseismic monitoring sensor installation device and installation method have been invented. On the premise of ensuring the monitoring effect, the method is convenient and fast to install and disassemble. The installation device and sensors can be recycled and used repeatedly, which greatly saves costs. Contents of the invention [0004] The object of the p...
