Reinforcing soil strength detecting device for shield construction and detecting method

The invention is suitable for the technical field of underground engineering tests and provides a reinforcing soil strength detecting device for shield construction and a detecting method. The reinforcing soil strength detecting device comprises a detecting assembly, a reacting force assembly and a support rod, wherein the detecting assembly is used for being inserted into reinforcing soil to carry out strength detection; the reacting force assembly is used for providing reacting force required by detection; and one end of the support rod is fixedly connected with the detecting assembly, and the opposite other end is fixedly connected with the reacting force assembly. The detecting method comprises the following steps: arranging the to-be-detected reinforcing soil, arranging the reinforcing soil strength detecting device in a region in which the reinforcing soil is arranged, locating a detection position and carrying out strength detection. In the invention, through the reinforcing soil strength detecting dev
