Pipelaying with pneumatic pipe hammer is widely adopted in the non-excavation constrution owing to its feature of simple constrution technique,high accuracy,fast speed and low cost.In the pipelay of short distance straight pipeline,it is a preferred choice,and is widely used for horizontal directional drilling engineering rescue.
The hammer's work theory:the Air Compressor offer the power for hammer,while pushing the oil into the shaft sleeve by hose for lubrication.The cone sleeve is put on the hammer head fixed by slip.Parts of soil will be cleaned out through the soil-out equipment while hammer working.The surplus soil in the pipe will be cleaned by humen when the project is over.
