The invention belongs to the technical field of shield construction, and provides a narrow space slurry shield launching method and a launching space.The launching method comprises the following steps that S1, vertical shaft mechanical equipment is adopted for construction at a designated position, and a launching working well is built; s2, hoisting and assembling pipe-jacking tunneling equipment by using the starting working well, and tunneling in a pipe-jacking mode through the pipe-jacking tunneling equipment to form a pipe-jacking section tunnel; and S3, after the pipe jacking section tunnel meets the specified distance, the pipe jacking tunneling equipment is transformed into shield tunneling equipment, then tunneling is conducted in a shield tunneling mode through the shield tunneling equipment, and a shield section tunnel is formed till remaining tunnel construction is completed. According to the launching method, the launching problem of the slurry balance shield in the narrow space is effectively sol
