Pipe jacking refers to a kind of hidden MBR reactor excavation construction method used when tunnels or underground pipelines cross various obstacles such as railways, roads, rivers or buildings.
During construction, the tube is pressed into the soil layer by means of a force-carrying jack and a guide rail, and the soil on the front of the pipe is excavated and transported. When the first section of pipes is all pushed into the soil layer, then the second section of pipes is connected to the back to continue to be ejected, so that a section of pipes is pushed in, the interface is made, and the culvert is built. The pipe jacking method is particularly suitable for the construction of culverts or rivers and lakes that pass through established buildings and lines of communication. Pipe jacking is divided into mechanical Rotating sludge scraper excavation jacking, extrusion jacking, hydraulic mechanical excavation and manual excavation jacking according to different excavation methods.
Pipe jacking method construction is an underground pipeline Mechanical fine screen construction method developed after shield construction, which was first applied in the North Pacific Railway laying project in the United States in 1896, and has a history of 100 years. In the 1960s, it was popularized and applied in countries around the world; In the past 20 years, Japan has researched and developed advanced pipe jacking heads and construction methods such as earth pressure balancing and hydrostatic balance pipe jacking machine.
