A mortise and tenon type internally connected prefabricated pile and its construction method

Abstract

The invention discloses a mortise and tenon type internally connected prefabricated pile and a construction method thereof. The prefabricated pile includes a pile tail mortise, a pile head mortise, a connecting bolt and a reinforced pile head block. The pile tail mortise is arranged at the tail of the prefabricated pile, and finally One section of prefabricated piles is not provided; pile tail sockets include pile tail connection steel cylinders, positioning chute and bolt notch, and a pile tail connection steel cylinder is arranged every 100mm along the length direction of prefabricated piles at a distance of 50mm from the tail of prefabricated piles. The installation angle of the last steel cylinder in the pile tail connection steel cylinder is that the direction of the previous steel cylinder is rotated 90 degrees around the center of the hole in the middle of the prefabricated pile; the two ends of the pile tail connection steel cylinder are sealed by rubber caps; the pile tail connection steel cylinder and A bolt notch is arranged at the joint of the outer wall of the prefabricated pile; a positioning chute is arranged at the position of the pile tail socket inside the prefabricated pile wall; the pile head tenon includes a positioning wedge and a pile head connection steel cylinder. The invention can realize the connection of two sections of prefabricated piles from the inside of the prefabricated piles.

Description

technical field [0001] The invention relates to the technical field of civil engineering construction, in particular to a mortise and tenon type inscribed prefabricated pile and a construction method thereof. Background technique [0002] The prefabricated piles can be manufactured in the factory, and the piles can be pressed on the construction site. The construction period is short, mass production can be realized, and the construction cost is reduced. Since the length of the prefabricated piles produced by the factory is generally 10 to 12 meters, when the engineering geological conditions are poor and a relatively long pile is required, it is necessary to connect the piles at the construction site. At present, the commonly used pile connection techniques include welding connection and flange connection. These two pile connection methods require pre-embedded steel rings at the connection pile heads. And there are following deficiencies: 1, when adopting welded connection...

AI Technical Summary

Problems solved by technology

And there are following deficiencies: 1, when adopting welded connection, in order to avoid the dislocation of the connecting pile head caused by welding deformation, two workers are required to weld symmetrically, which requires higher technical level of workers and requires higher labor costs. The connecting steel ring is easy to corrode under the action of welding residual stress

2. When the flange is used for connection, the section of the connected pile head will be larger than the section of the pile body, which will increase the difficulty of pile pressing, and the flange is also prone to corrosion in the soil
