Abstract
The invention discloses a construction method for layered construction hole forming of a rock-socketed secant pile in a riprap area near sea, and relates to the technical field of secant pile construction. According to the construction method, a sleeve is matched with a full-rotary drilling machine to drive the sleeve to rotate and follow up, a sand layer, a full-weathering layer, a strong-weathering layer and other soft soil layers adopt a rotary drilling cutting tooth drill bit to take soil, a riprap layer adopts a heavy hammer, a punching grab bucket and a cone cylinder drill to cooperate with punching to take rock, a medium-weathering layer, a micro-weathering layer and other hard soil layers adopt a rotary drilling matched with the cone cylinder drill to carry out hole forming construction, the full sleeve follows up to a rock layer in the construction process, and after a pile hole is finished, a guide pipe is adopted to carry out underwater concrete pouring method construction. According to the construction method, the influence of the tidal water level on the pile hole is solved, meanwhile, the technical difficulty that the formed hole penetrates through the riprap layer is solved, the construction method can be suitable for secant pile construction of a complex stratum, quicksand or sludge in the pile hole is effectively prevented, the construction is safe and rapid, the construction quality of the secant pile is guaranteed, and meanwhile, the construction period can be shortened.
Description
technical field [0001] The invention relates to the technical field of occlusal pile construction, in particular to a construction method for forming holes by layered construction of rock-socketed occlusal piles in a riprap area near the sea. Background technique [0002] The occlusal pile row pile is a support form applied to foundation pit support. Because it has two functions of support and water-stop, it has good integrity, high rigidity, and strong ability to control the deformation of the foundation pit. The construction is harmful to the surrounding buildings. Because of the advantages of small physical impact, it is widely used. The traditional occlusal pile construction technology is suitable for all geological conditions except large rock formations, especially suitable for unfavorable formations with rich groundwater, and the effect is excellent. [0003] For seaside areas containing large pieces of rubble or riprap, the stratum is more complex, affected by vario...
