XCMG XDN2800-R pipe jacking machine

overcame 130 MPa hard rock

successfully completed the jacking operation for the water transmission and distribution project

setting a new domestic record for a single jacking distance at 1310 m

The project is located in Binzhou City, Shaanxi Province, and aims to solve the local problems of water resource shortage and insufficient development, which is of great significance for improving the living conditions of the general public.

The hydrogeological conditions of the Binchang mining area are relatively complex, with special geology such as uneven soft and hard strata, faults, and karst, and groundwater is abundant and highly permeable.

After conducting research and comparison with multiple parties in China, the project department learned that XCMG XDN series pipe jacking machines have many successful construction cases at home and abroad, and immediately decided to use the XCMG XDN2800-R pipe jacking machine for construction.

trenchless construction, no need to block traffic

laser guidance, meeting the slope requirements of gravity-flow pipelines

small over-excavation and minimal construction settlement

XCMG XDN rock pipe jacking machine

with outstanding construction capability and technical advantages

has repeatedly achieved excellent results in multiple complex projects

Hefei Jianghuai Water Diversion Paihe River Sewage Interception and Diversion Water Quality Protection Project

The XCMG XDN rock pipe jacking machine successfully achieved long-distance jacking construction of 1187.5 m with a new type of pipe material and a large diameter of 2.4 m;

Shaanxi Binchang Mining Area Water Transmission and Distribution Project

A single jacking of 1310 m, including a 1260 m curved section with a curve radius of 999 m and rock strength of 70–130 MPa, set a new record for the longest jacking interval in China.

The XCMG XDN2800-R rock pipe jacking machine was able to complete construction under such complex and harsh geological conditions thanks to its powerful performance:

High torque and high rotation speed: effectively solves the industry problem of high-frequency reducer overheating, increases the cutterhead rotation speed, and enhances overall construction efficiency;

Refined jacking speed control technology: the control system achieves refined adjustment of jacking through a combination of large and small flow rates;

Efficient mucking technology: five slurry circulation modes greatly improve the equipment's adaptability to strata.

To ensure the smooth progress of the project, XCMG dispatched professional personnel to provide on-site guidance and cooperated with the project department to continuously optimize the construction process. With the smooth progress of the Binchang Mining Area Water Transmission and Distribution Project, the water resource transmission and distribution system in Northwest China has been effectively improved.
