Dry-method hole forming filling pile structure for post-grouting matched rotary drilling rig and construction method
The invention discloses a dry-method hole forming filling pile structure for a post-grouting matched rotary drilling rig and a construction method. The filling pile structure comprises a hole pile body arranged in a terrace. The hole pile body is composed of concrete and a steel reinforcement cage arranged in the concrete. The steel reinforcement cage comprises cylindrical main ribs which are evenly distributed. Hoop ribs and reinforcing hoops are arranged on the outer sides and the inner sides of the main ribs respectively. Multiple grouting pipes are evenly arranged in the circumferential direction of the steel reinforcement cage. The construction method includes the steps that firstly, a site is cleaned and leveled; secondly, measurement and take-off operation are performed and a pile position is buried; thirdly, the drilling rig is in place and drills the surface layer and a steel protective barrel is buried; fourthly, the center line of the pile is rechecked; fifthly, a pile hole is drilled; sixthly, a bearing stratum and the formed hole are checked; seventhly, the hole is cleaned; eighthly, a grouting pipe is manufactured and installed; ninthly, the steel reinforcement cage is lifted to be in position; tenthly, a concrete pouring guide pipe is installed; eleventhly, the concrete is poured; twelfthly, the grouting pipe is cleared out through clean water; and thirteenthly, grouting is performed. By the adoption of the structure and the method, the side friction resistance force of a rock-socketed section of the end of the pile is improved.
