The detection tool comprises a sealing cover, a lining plate, a double-end bolt, a pressure gauge and a valve, the detection method comprises the specific steps of cleaning, detection tool installation, lifting inflation, detection and pressure relief. The detection tool is simple in structure and convenient to disassemble and assemble, the sealing cover and the lining plate are used in cooperation, the sealing performance of the diaphragm during detection is guaranteed, the detection tool can be used in cooperation with hoisting equipment during detection, and follow-up operation development is facilitated; by adopting a detection method of filling carbon dioxide and a litmus solution, the damage position can be quickly and accurately determined, the detection time is saved, and the detection efficiency is improved.
