🟧 Pipe Jacking
Pipe jacking is an advanced technique for installing underground pipes, channels and pipes for electricity and telecommunications. At the same time as the special pipes are driven by very strong hydraulic jacks, the drilling operation is also done inside the shield and in front of the leading pipe. This method creates a flexible, resistant and watertight pipeline like a tunnel. Theoretically, there is no limit to the length of the pipeline route by pipe jacking, however scientific, engineering and economic considerations may be in Actions create restrictions. With this method, several meter long routes can be executed as a straight route or a curved route or a combination of the two. Different modes of drilling systems include manual drilling (Hand Shield) and mechanical method (Mechanical Shield).
🟧 Technique of Jacking Pipe
To install a pipeline using this method, sending and receiving shafts are usually built at the beginning and end of the route. The dimensions and the way of constructing the shaft changes according to the specific needs of each route, and economic issues are considered a key factor among them. Compared to manual drilling, mechanical drilling methods mainly require larger shafts, at the same time, environmental and traffic conditions are the most important factors in determining the dimensions of the transmission shaft, among which the use of devices with the ability to change the length of the main chassis, in the direction of the pipe thrust. With different lengths, such as the Venon device, it is introduced as the final solution to meet the special conditions of the work place in smaller shafts.
