new generation screw pile machine put on the market
June 19, 2019
The screw pile driver is designed to have a hole depth of 24 meters. The biggest difference between the long auger and the long auger drilled by the company is that the two pile machines are different in hole shape. The thread pile machine is threaded (equivalent to an internal thread), long auger The inlet hole is cylindrical. Compared with the cylindrical hole, the thread-like hole will increase the bearing capacity, and greatly reduce the amount of concrete poured and reduce the construction cost. Therefore, the advantage is obvious and the market prospect is very broad.
The advantage of the pile driver is obvious, but its production difficulty is much more than that of the long screw pile machine. Because in order to leave a complete threaded pile into the hole in the soil layer, the rotation speed of the drill pipe must be synchronized with the falling (or rising) speed to ensure the thread formation, otherwise the thread will be completely destroyed. In response to this technical problem, the technicians have repeatedly studied and determined the method of using frequency conversion speed regulation to achieve a synchronous solution. In the trial production, some parts were redesigned and fabricated. The steel structure part changed the original main column and the hinge hinge joint used by the platform to the current cross shaft connection, and the structure is more stable; the main winch uses 8 tons. The hydraulic winch drive replaces the previous motor drive and adds a pressurizing device to meet the design requirements. In addition, it is equipped with equipment such as main column angle tester and level tester, which makes the performance of the pile driver more superior.
