The invention relates to a jet grouting pile forming diameter detection device. The jet grouting pile forming diameter detection device comprises a hollow pipe, vibration sensors and signal processingequipment. The hollow pipe parallel to a designed pile body is arranged at the edge position of the preset pile forming radius, and at least two guide rails are arranged on the inner wall of the hollow pipe in the direction parallel to the axial direction. The multiple vibration sensors are arranged on the guide rails in the hollow pipe at intervals. The vibration sensors are connected with the signal processing equipment, and the signal processing equipment is connected with a control system. The vibration sensors are used for detecting vibration parameters of the hollow pipe caused by high-pressure fluid jetted by a drill rod at the position of a middle shaft of a self-rotating jet pile. Real-time monitoring is achieved, and whether the pile diameter and the pile length meet the designrequirement or not can be visually judged; and the pile forming quality of the pile body at the corresponding height can be obtained. The operation is simple, and steel pipes and the sensors can be recycled; and detection is carried out in the construction process, and real-time feedback can be achieved.
