The invention provides a jacking-pushing drilling construction device and method of an underground pipeline. The jacking-pushing drilling construction device of the underground pipeline comprises a guide drilling rod, a jacking machine head and a pushing mechanism. Cutting blades are arranged on the front end face of the jacking machine head at intervals, and the top of the jacking machine head is provided with a first connecting mechanism connected with the guide drilling rod; and a second connecting mechanism connected with the pipeline is arranged at the bottom of the jacking machine head, and a high-pressure water gun for discharging mud in the jacking machine head is arranged in the jacking machine head. The cutting blades are arranged on the front end face of the jacking machine heat at intervals, mud on the working face can be extruded into the jacking machine head and the pipeline, and the mud can be discharged from a starting well through the pipeline; and the mud can be effectively discharged while the soil pressure of an egg gravel layer is reduced.
Description
technical field [0001] The invention relates to the technical field of pipeline construction, in particular to a jacking drilling construction equipment and method for underground pipelines. Background technique [0002] In recent years, in the construction of municipal or industrial pipeline projects, it is necessary to lay many pipes with different diameters, including water pipes, sewage pipes, rainwater pipes, underground passages, gas pipes, heat pipes, etc. The traditional method of digging trenches and burying pipes has many disadvantages, such as affecting traffic, damaging road surfaces, destroying surface vegetation, affecting normal commercial activities and daily life of residents, and a large number of earthworks. The jack-push drilling technology adopted in recent years can overcome the shortcomings of the above-mentioned excavation method. [0003] When the compacting type reaming is used, the resistance is too large, and the pipe jacking cannot be advanced; ...
