Abstract

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.

Description

technical field [0001] The invention relates to the technical field of urban construction pipeline construction, in particular to a pipe jacking construction method for small-diameter pipelines. Background technique [0002] With the development of urban construction, especially the acceleration of old city reconstruction, various types of small-diameter pipeline burying projects are increasing, but traditional slotting construction is becoming less and less suitable for construction due to damage to roads, impact on traffic, and environmental pollution. need. Therefore aim at the problem that existing construction method exists, need to propose a kind of pipeline laying construction technology that is used for the lesser sewer pipeline of caliber, gas, electric cable, communication. Contents of the invention [0003] The inventor of the present invention has put forward a kind of pipe laying construction technology mainly suitable for sewer pipes, gas, electric cables an...
