Description

Technical Field

[0002] In recent years, with the development of my country's economy, infrastructure construction has flourished across the country. There are a large number of soft soil areas in the east and southeast of my country, especially in coastal provinces. The coastline is mostly muddy coast, and the soil is mostly silt, silty clay and silty silt clay, etc., with high water content, large porosity, low density, low strength, high compressibility, low permeability and other characteristics. Soft soil bases often need to be reinforced due to their poor bearing capacity. Concrete pipe piles are increasingly used in the treatment of soft soil foundations due to their own advantages and characteristics. Its main advantages include high single pile bearing capacity, wide range of design options, multiple specifications, strong adaptability to geological conditions with large fluctuations in the bearing layer, low cost of single pile bearing capacity, convenient transportation and hoisting, quick pile connection, pile length is not limited by construction machinery, fast construction speed, high work efficiency, and short construction period.

[0003] There are three methods for pipe pile construction: hammering, static pressure, center excavation, and implantation. The main construction methods at present are hammering and static pressure. The static pressure method is a construction method that uses a hydraulic or clamping pile driver to press the pile into the soil through its own weight and the support reaction force. The hammering method is a construction method that uses a diesel hammer or a hydraulic hammer pile driver to hammer the pile end through the gravity potential energy and height potential energy of the drop hammer to drive the pile into the soil. As a result, the requirements for precise positioning of pipe piles are getting higher and higher, and the hollow part in the middle of the pipe pile cannot be directly set up with instruments for measurement and layout, which brings many inconveniences to the construction.
