The components and working principle of the pipe jacking machine

The components and working principle of the pipe jacking machine are different according to the model. The pipe jacking machine is composed of at least two parts, one is the cutting tool tube (the front part of the pipe jacking machine), and the other is the shield tail. These two parts are usually cylindrical pipes and are connected to each other by a hinge.

In this case, the cutting tool tube is supported by the guide cylinder at the tail of the shield, and its function is to control the jacking direction and provide space for accommodating the crushing tools (cutter heads and excavators, etc.), and also serve as a crushing space for the rock and soil.

The pipe jacking machine is sometimes composed of three parts, the second part is called the middle tool tube (the middle part of the pipe jacking machine), and the third part is called the shield tail, which is the transition part between the pipe jacking machine and the jacking pipe.

For larger diameter pipe jacking machines, the pipe next to the pipe jacking machine can also be used as a subsequent part of the pipe jacking machine in order to accommodate the required construction machinery.

Vacuum Tube Collectors include CPC Solar Collector, U-shape solar collector without CPC, heat pipe Vacuum Tube Solar Collector, LPC open loop collectors. No matter pressurized or non-pressurized collectors, they are called Vacuum Tube solar collector once it consists of all glass Vacuum Tubes .

CPC solar collector is the highest efficiency among all Vacuum Tube Solar Collectors.

Advantages and benefits
- Short installation times due to complete pre-assembled collectors. 
- Simple and reliable connection technology in order to extend several collectors side by side through pre-assembled screw connections. Further tubing and an extensive thermal insulation is not necessary. 
- Integrated return pipe and highly efficient thermal insulation. 
- Manageable module sizes for a very high performance and a quick and easy installation. 
- Flow and return pipes may be fitted on the left or the right side of the manifold. 
- High flexibility due to the different widths and lengths of the collectors. 
- Quick and easy exchange of the evacuated tubes without using any tools.
