The invention discloses a pipe-jacking construction method for a mealy sand stratum. The pipe-jacking construction method for the mealy sand stratum comprises the steps that firstly, a working well is constructed, specifically, the working well used for jacking a constructed underground pipeline is constructed, the constructed underground pipeline is formed by splicing a plurality of pipeline assembly sections from front to back, and a steel bushing head tool pipe comprises a steel sleeve, a supporting ring mounted on the inner side of the rear end of the steel sleeve, and an insertion opening fixed to the supporting ring; secondly, jacking equipment is mounted, specifically, the jacking equipment is mounted at the bottom of the inner side of the working well; thirdly, the steel bushing head tool pipe is jacked through the process that the steel bushing head tool pipe is hoisted in place, the steel bushing head tool pipe is jacked, and manual intra-pipe earth cutting is conducted; fourthly, the pipeline is jacked, specifically, the multiple pipeline assembly sections of the constructed underground pipeline are jacked from front to back; fifthly, a pipeline port is treated; and sixthly, a closed water test for the pipeline is conducted. According to the pipe-jacking construction method for the mealy sand stratum, the steps are simple, the design is reasonable, construction is easy and convenient, and the using effect is good; and a pipe-jacking construction process of the mealy sand stratum can be completed easily, conveniently and rapidly, and the construction process is safe and reliable.
