Detection method of compression strength of concrete structure

The invention relates to a detection method of compression strength of a concrete structure. The detection method is characterized by comprising the following steps of: a, utilizing a motor (4) with fixed outputting power W to drive a sizing drill bit (2); by utilizing a fixed energy E, pushing the motor (4) to cause the drill bit to drill into the concrete; and when the fixed energy E is completely released, drilling a deep hole on the concrete by the drill bit, and measuring a drilling depth H; and b, substituting the drilling depth H measured on the concrete structure into a formula f=AHB for a strength measuring curve, so as to obtain the compression strength of the structural concrete. The beneficial effects of the detection method are as follows: the structural concrete compression strength is tested by utilizing the different depths that the sizing drill bit is drilled into the concretes at different strength grades under the driving action of the motor and the pushing action of the same energy; the di
