Installation method of cast-in-place pile lateral soil mass pressure detection system

The invention provides an installation method of a cast-in-place pile lateral soil mass pressure detection system. The installation method of the cast-in-place pile lateral soil mass pressure detection system comprises the following steps of: step A. laying a supporting net on the cross section of a reinforcement cage in a length direction; step B. fixing a soil pressure box on the end of a propulsion device, then fixing the propulsion device on the supporting net, and arranging the soil pressure box at the outer side of the reinforcement cage; step C. adjusting the reinforcement cage to be ina vertical direction, so that the reinforcement cage is put in a hole of a cast-in-place pile; step D. pressurizing the propulsion device so as to enable the soil pressure box to push against the wall of the hole of the cast-in-place pile, and finally carrying out concrete pouring; and step E. after the strength of the cast-in-place pile meets the requirements, carrying out soil mass lateral datameasurement and collectio
