What should I do before HDD machine working?
Ⅰ. Construction preparation 1. Before construction, the center line of the planned pipeline should be laid out according to the design drawings, the entry point and exit point should be determined, and the position of crossing obstacles and crossing pipelines should be marked on the center line; according to the entry point, exit point and […]
Pipe pushers VS Pipe jacking machines
Both pipe pushers and pipe jacking machines play an important role in pipeline construction, but they have obvious differences in working principles, scope of application, usage scenarios and usage effects. The following is a detailed comparison of the two: 1. Working principle Pipe pushers: Use high-pressure compressed air or other power sources to convert the […]
What is Horizontal Directional Drilling
As urban underground pipeline networks become increasingly dense, Horizontal Directional Drilling (HDD) has emerged as one of the most essential trenchless construction technologies. It enables the precise installation of gas, water, power, and telecommunication pipelines without large-scale road excavation, and is widely used in municipal renovations, long-distance transmission lines, and environmental projects. What is HDD? Horizontal Directional […]
