Drill rod capable of detecting perpendicularity of drill rod of cast-in-situ bored pile and detection system

The invention relates to a drilling rod capable of detecting the perpendicularity of a drilling rod of a cast-in-situ bored pile and a detection system. The drilling rod mainly comprises the drilling rod with an inner rod wall and an outer rod wall, a pressure sensor, a temperature sensor, a sensor information collecting and processing system and a drilling rod perpendicularity data visual displaying and prompting system. By improving the structure of the drill rod and arranging the detection system, dynamic detection of the perpendicularity of the drill rod in the drilling process can be achieved, the defect that detection can only be conducted after hole forming is completed in a traditional detection method is overcome, and the construction quality and efficiency can be improved easily; according to the invention, automatic acquisition and calculation of verticality data can be realized through the sensor and the detection system, the operation is convenient, manual reading by using a total station, a leve
