Embodiment Construction

[0012] A construction method for in-wall grouting pipe piles,

[0013] (1) When the concrete pipe pile is prefabricated, the grouted steel pipe is embedded in the concrete pipe pile wall, which is used not only as the grouting pipe, but also as the reinforcement of the concrete pipe pile (not only has the function of grouting, but also ensures the strength of the pipe pile, play the role of bending resistance, bending resistance and compression resistance), the diameter of the grouted steel pipe is 1-5cm, the number is 2-8, and the distribution is circular and equidistant; the grouted steel pipe is on the side and end of the concrete pipe pile There are threaded grouting holes (it can be punched downwards or on the side to reduce friction); the distance between the grouting holes on the pile side is 50-500cm; the diameter of the pile bottom is set to be 1-30cm larger than the outer diameter of the pipe pile. End plate (can be cross-shaped, X-shaped, Y-shaped, etc.), the end pl...

Abstract

The invention discloses a construction method of a pipe pile adopting grouting inside the wall. When a concrete pipe pile is prefabricated, grouting steel tubes are embedded into the wall of the concrete pipe pile, and the grouting steel tubes are used as grouting tubes and also as reinforcing bars of the concrete pipe pile. The diameter of each grouting steel tube is 1-5 cm, the number of the grouting steel tubes is 2-8, and the grouting steel tubes are circularly distributed at equal intervals. The grouting steel tubes are provided with threaded grouting holes located on the pile side and the pile tip of the concrete pipe pile. The intervals between the grouting holes on the pile side are 50-500 cm. An enlarging end plate with the diameter being 1-30 cm larger than the outer diameter ofthe pipe pile is arranged at the pile bottom. Holes are reserved at the positions, of the threaded grouting holes, on the end plate. The end plate is welded to a pile body or is flexibly connected with a steel strand embedded into the pile body. The length of the steel strand is 5-30 cm. A wireless pressure sensor is arranged in the end plate. The construction method of the pile achieves convenient construction and is excellent in construction effect.

Description

technical field [0001] The invention relates to a pile construction method. Background technique [0002] During the existing pile construction, the grouting pipe is set in the inner cavity or outside of the pipe pile, which has a single function and unsatisfactory performance; moreover, common construction methods such as static pressure piles are complex in construction and poor in construction effect, and need to be further improved. Improve. Contents of the invention [0003] The purpose of the present invention is to provide a construction method of piles with convenient construction and good effect. [0004] Technical solution of the present invention is: [0005] A construction method for in-wall grouting pipe piles is characterized in that: [0006] (1) When the concrete pipe pile is prefabricated, the grouted steel pipe is embedded in the concrete pipe pile wall, which is not only used as the grouted pipe, but also as the reinforcement of the concrete pipe pile...
