(Summary description)Rock pipe jacking machine pipe jacking construction is an underground pipeline construction method following shield construction and development. It does not require surface layer excavation, crossing roads, railways, rivers, above-ground buildings, underground structures and various underground pipelines. The main cylinder and pipes of the repeater or the like, the top of the pipe or the machine tool work through the soil and the pipe jacking force device that has been pushed by the top of the well is received and released. After the boring machine or the pipeline is embedded between the wells, the pipeline is immediately installed. The construction method realizes the trenchless underground pipeline laying. Rock pipe jacking machine design manufacturing engineer top tunneling equipment components. The core technology of roadheader design and rich construction experience, suitable for the geological conditions of various pipe jacking equipment manufacturing-roadheader, mud-water balance pipe jacking machine, EPB rock top and top auxiliary equipment of drilling and boring machine 500 sets of equipment 4000 Millimeter diameter is 400 millimeters. The driving modes of the top boring cutter disc are: mechanical drive, hydraulic drive, and frequency conversion motor drive mode. Not only design, production, but also actively participate in the guidance of pipe jacking, pipe jacking technical training, and pipe jacking construction program demonstration. The protection of the surrounding living environment by the pipe jacking machine during construction: Manual pipe jacking machine. The rock pipe jacking machine and the artificial pipe jacking machine have no positive support, which is prone to collapse during the construction process, resulting in large ground settlement. In accordance with the basic conditions of stability, a manual pipe jacking machine can be considered. After the soil is disturbed, the shear strength is reduced, and the excavation surface with a large exposed area is prone to spalling and collapse. When the outer diameter of the tool pipe is larger than the outer diameter of the tool pipe, a support shall be provided on the excavation surface. When the stability is poor, auxiliary measures such as air pressure construction shall be adopted. Improved industrial production and provided convenience in mechanical production.
