Abstract

The invention discloses a detection method for the static load of a pile foundation, which comprises the following steps of: 1, installation: pre-embedding more than one anti-pulling draw bar at the top of a pile foundation to be detected and connecting the anti-pulling draw bars with the pile foundation to be detected into a whole, and sticking a carbon fiber layer on the outer wall of the pile foundation to be detected, wherein the height for sticking the carbon fiber layer on the pile foundation to be detected is greater than or equal to the length of the anti-pulling draw bar embedded in the pile foundation to be detected; 2, connection: connecting the top of the anti-pulling draw bar with a detection component through a draw bar sleeve; and 3, detection: measuring and recording the original elevation of the pile foundation to be detected, and applying force to the anti-pulling draw bar through the detection component; recording the elevation change condition of the pile foundation to be detected each time one-level load is added according to the force loading order; and after the force is completely loaded, obtaining the static load condition of the pile foundation according to the obtained data. The detection method has advantages of simple principle, easy operation, high safety, high detection precision, wide application range, high detection efficiency, time saving and economy.

Description

technical field

[0001] The invention mainly relates to the fields of buildings and foundations, in particular to the detection of static loads of pile foundations. Background technique

[0002] With the continuous development of the construction industry, there are more and more projects using pile foundations. However, with the widespread use of pile foundations, major engineering quality accidents caused by foundation, pile body quality and other reasons occur from time to time. In order to ensure the safety of engineering structures and the safety of life and property of the country and the people, pile foundation detection is becoming more and more important, especially the static load compression and pullout detection of medium and small diameter cast-in-place piles and tubular piles that are widely used Technology is even more important.

[0003] The traditional static load testing methods for vertical compression and pullout of pile foundations include: surcharge me...
