In recent years, it has risen rapidly in the field of underground pipeline construction，In order to make full use of urban underground space resources,，Ensure the sustainable development of cities，More and more pipelines are laid by Trenchless pipe jacking.。With the continuous improvement of engineering construction requirements,，The technology is backward、Inefficient manual excavation is being phased out，Trenchless technology has been first popularized in large and medium-sized cities.，It will further open up more market space in the future.。As a co-sponsor，Shanggong Machinery deeply participated in the training.，Self-work machineryPJRSeries micro pipe jacking drilling rig、PITSeries of press-in shaft pipe rubbing machines have been introduced to the market.，By virtue of maneuverability、Reliability、Security、Comprehensive competitive advantages such as high efficiency will soon stand out in the market.，It has won the general favor of users everywhere.。

 

▲Discussion on Trenchless Technology between Shanggong Machinery and Trainees

The Central Economic Work Conference in 2021 particularly emphasized，“Fourteen five”Period，Pipeline reconstruction and construction must be taken as an important infrastructure project.，It is clearly required to speed up the aging and renovation of urbanized pipelines.，At the same time, the Ministry of Housing and Construction and the provincial housing and construction departments issued the policy that urban roads should not be excavated at will.，“Disembowel”The way pipelines are laid is out of date.，“Minimally invasive”Technology is the trend and direction of pipeline laying，Trenchless technology is the pipeline.“Minimally invasive”Technology，Broad prospects for future development。

PJRSeries micro pipe jacking drilling rig：

Miniature pipe jacking in water supply and drainage pipelines、A branch of a gas pipe、Electricity、It is widely used in communication and other pipelines.。The pipe jacking construction method is to install a pipe jacking rig in the working well first.，The spiral drill rod is firstly drilled into the soil along the central axis of the pipeline to determine the direction of the pipeline,，Reaming to the designed pipe diameter with a spiral reaming bit，The pipe to be laid follows the auger bit，Under the action of the thrust of the main oil cylinder, the tool pipe digs into the soil layer，The excavated soil is discharged by a soil pump or a screw conveyor or in the form of slurry through a pipeline by a slurry pump.，After pushing one section of pipeline，Main Jack Retracted，Hoist another section of pipe，Keep jacking。And so on，Until the pipeline is laid。After the pipeline is laid，The tool pipe is hoisted to the surface from the receiving well。

 

Performance characteristics：■ Small construction area、Do not destroy the existing road，The impact on traffic is small；■ The construction noise is low，Less sludge discharge，Little impact on the environment，High degree of safe construction；■ And that construction precision is high，Advanced technology，The construction speed is fast，Low comprehensive construction cost。
