The invention discloses a combined casing
pipe suitable for tunnel tsp forecast, a
system, and a method. The casing
pipe is easy to assemble, is convenient to recycle, and is simple in measurement. An inner casing
pipe and an outer casing pipe are in threaded connection, thereby achieving a function of protecting a sensor. Surrounding rocks, the sensor and the casing pipes are tightly coupled together, thereby guaranteeing the collection efficiency of signals. Meanwhile, the threaded connection can enable a part of components of the casing pipe to be recycled, thereby reducing the consumption of the casing pipe and improving the
economic benefits. An angle measurer completes the measurement of the
azimuth and inclination angle of the casing pipe through a built-in
gyroscope. Most of parts are made of resin material with certain
plasticity and steel, and the components are combined in a separated or segmented manner. The casing pipe can effectively protect the
coupling among the sensor, the casing pipe and the surrounding rocks, and guarantee that the sensor can achieve the effective receiving of a TSP detection
signal. Meanwhile, a part of components of the casing pipe can be recycled, thereby reducing the consumption of the casing pipe and improving the
economic benefits.
