Pre-bored Pre-cast Piling Equipment

Product Detail

Product Main Features: 1. No soil-squeezing, no vibration, noiseless 2. Great pile-forming quality, completely controllable of pile top elevation 3. Strong vertical compression, pull and horizontal load resistance 4. Low mud discharge 5. Good social benefit and promotion value PRE-BORED PRE-CAST CONCRETE PILE METHOD PRE-BORED PRE-CAST CONCRETE IMPLANTED PILE TYPE COMBINATION Implanted pile: Precast pile with a certain combination of prestressed high strength concrete knot diversion pile (PHDC), prestressed reinforced high strength concrete pile (PRHC), prestressed high-intensity concrete pile (PHC), etc. 1. According to the geological conditions, select the appropriate pile type to increase lateral and pile tip resistance. 2. Improve the resistance level and uplift bearing capacity of pile body 3. Prestressed high strength concrete knot pile (High-performance concrete implanted pile) (For short: PHDC) Prestressed high-performance concrete pile with hot rolled ribbed steel bar. The lateral resistance of the pile can be greatly increased through the interlocking between the pile and the surrounding area The resistance characteristics of pile tip can be improved by underside extension. 4. Prestressed reinforced high strength concrete pile (For short: PRHC) Prestressed reinforcement, non-prestressed reinforcement, End plate anchorage The pile is using for upper segment pile of pile foundation, it can meet the high requirements of resistant compression, pulling and horizontal load. Can partly replace steel pipe pile EQUIPMENT TECHNOLOGY ADVANTAGES With accumulated technology advantages of deep soil mixing drill, SEMW completely independent research and develop SDP Series Pre-bored Pre-cast Piling Equipment, a new generation of drilling equipment which is suitable for the static drilling method. The main parts are international famous brands, which have the characteristics of high torque, great drilling depth, high scientific and technological content, good reliability, high construction efficiency, and the performance reaches the international advanced level. 1. SEMW SDP Series adopts the advanced oil pressure root-enlarging technology, the root diameter is 1~1.6 times of the diameter of drilling hole and the root height is 3 times of the drilling hole’s diameter. In addition, advanced slave computer software history data recording method is adopted to record various construction process data of the same kind of imported products, such as borehole depth change, drilling speed, construction process current, temperature condition water flow of borehole, root-enlarging monitoring, amount of cement injected around pile tip etc. Setting and storage of relevant construction data, such as construction unit, site number, pile number, completion status, etc., can also be used to analyze various construction data and form corresponding data curves. 2. Intelligent construction management software is adopted to control the use of intelligent touch screen mode to monitor the construction process in real time. Ensure the construction quality and all construction data are clearly reflected on the display and stored automatically, which can be printed out. 3. The SEMW SDP Series operating system is equipped with the power loss 380V automatic shutdown program. It ensures that the data will not be lost due to the crash or power failure during the operation of the drill. 4. The SEMW SDP Series motor start mode adopts soft start. The soft starter itself has various motor protection functions, such as under-voltage, missing phase, phase sequence, overload, etc. Besides, it has good cooling function and can be started frequently. 5. The technology of hydraulic root-enlarging has reliable performance and adopts excellent hydraulic components to ensure the normal operation of hydraulic root-enlarging under depth of 80m. Drilling tools are specially designed and manufactured with high strength, good bending and high wear resistance to reduce the maintenance costs. Product Model: SDP 110H 150H 220 Specifications:
