Calculation method of inclination angle of arbitrary section of pipe pile based on horizontal inclinometer

Abstract

The present invention relates to the technical field of construction, in particular to a method for calculating the inclination angle of any section of a pipe pile based on horizontal inclinometer, comprising the following steps: step 1, splicing corresponding inclinometer pipes according to the length of the pipe pile; step 2, horizontally aligning the pipe pile Place it, seal half of the pile holes on both sides, pour 15-25mm thick cement into the inner hole for self-leveling; step 3, bond the inclinometer tube to the cement self-leveling with adhesive; step 4, drive the pile into the test site , to detect after the rest period; step 5, use the inclinometer to measure the horizontal displacement of the pile under a certain level of load and derive relevant data, and use an 8th degree polynomial to fit the horizontal displacement curve of the pile body. This method obtains the inclination angle of any section of the pipe pile by fitting the horizontal inclination of the pile body, and its accuracy meets the engineering requirements. It can provide a scientific basis for the dynamic analysis of the pipe pile under horizontal loads and even earthquakes, and provide a basis for the next step of pipe pile foundation seismic Design lays technical support.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a method for calculating the inclination angle of an arbitrary section of a pipe pile based on horizontal inclinometer. Background technique [0002] With the partial revision of GB50011-2010 "Code for Seismic Design of Buildings", the requirements for the seismic performance of buildings have been further deepened, and the research on optimization measures for the upper structure is basically mature. The stress and deformation properties of pipe piles are not yet clear, so the research on the stress and deformation of pipe piles under the action of horizontal force has become an urgent requirement. [0003] Judging from the existing patents, on the one hand, the detection density of the inclination angle of the section of the pipe pile body is too sparse and inaccurate to provide a basis for the research on the seismic performance of the pipe pile body; on the other hand, b...

Problems solved by technology

[0003] Judging from the existing patents, on the one hand, the detection density of the inclination angle of the section of the pipe pile body is too sparse and inaccurate to provide a basis for the research on the seismic performance of the pipe pile body; on the other hand, based on the current detection methods, the cost Too high to promote the application on a large scale

[0004] To sum up, currently there is no practical and effective method for detecting the inclination angle of the section of pipe piles from multiple perspectives such as technology and economy.
