The invention provides a pipe-jacking construction method for small-diameter pipes. The pipe-jacking construction method includes the steps of surveying and paying off, working well and receiving well manufacturing, pipe-jacking device mounting, pilot drilling, reaming, pipe pulling, other pipe construction in sequence, pipe-jacking device dismounting, pipe head handling and inspection well and cable channel construction. By the pipe-jacking construction method, excavation volume is low, slurry discharging is less, roads are not destroyed, and comprehensive cost is low; construction can be performed all through the year, construction speed is high, project circle is short, construction of an overall design project can be quickened, and working efficiency can be improved; traffic interference is minimized, and normal conditions of traffic in a construction site are guaranteed; environmental pollution like noises and dust cannot be generated, urban environment protection and stability, optimal design of the total planning and engineering construction of the urban construction can be benefited, and urban modern planning programming and construction level can be beneficially improved.
