Multi-working-condition simulation combination device for foundation pile low strain detection

Abstract

The invention relates to a multi-working-condition simulation combination device for foundation pile low strain detection, which comprises a cylindrical simulation pile, a shading bag is sleeved outside the simulation pile, the simulation pile comprises at least one first pile body, the head end of the first pile body is provided with a first threaded column, and the tail end of the first pile body is provided with a first screw hole matched with the first threaded column; the simulation pile further comprises a male end socket and a female end socket, the male end socket comprises a cylindrical first column body, and a second threaded column matched with the first screw hole is arranged at the head end of the first column body; and the female end socket is a cylindrical second cylinder, and the tail end of the second cylinder is provided with a second screw hole matched with the first threaded column. The multi-working-condition simulation combination device for foundation pile low strain detection is small in occupied area, easy and convenient to mount and dismount, low in cost and small in site limitation; and after random combination, the simulated defect sample size is large,and the implementation effect is good.

Description

technical field [0001] The invention relates to a multi-working-condition simulation combination device for low-strain detection of foundation piles, belonging to the technical field of low-strain detection. Background technique [0002] Foundation engineering is an important part of construction engineering. The quality of foundation engineering is directly related to the structural safety of the entire building. Therefore, the quality acceptance of foundation piles is very important. According to the Ministry of Housing and Urban-Rural Development of the People's Republic of China According to the requirements of the national standard "Code for Design of Building Foundations" GB50007-2011 and the industry standard of the People's Republic of China "Technical Specifications for Building Pile Inspection" JGJ / T 106-2014, the engineering piles after construction should be tested for pile bearing capacity and pile body Integrity inspection, among which the integrity inspection ...

AI Technical Summary

Problems solved by technology

[0009] 1. Generally, the offices of testing institutions or training institutions are located in urban areas. Due to factors such as site and construction technology limitations and high production costs, the number of concrete simulation piles set by general units is limited. At the same time, the types of defects in concrete simulation piles that can be set and limited places

[0010] 2. It is difficult to simulate many defects that may occur in the actual inspection process with limited concrete simulation piles, and it is difficult to cultivate the comprehensive analysis level of inspectors to deal with various defect situations only by limited concrete simulation piles

[0011] 3. Due to reasons 1 and 2, the samples of typical defects in pile foundation construction that can be simulated by general concrete simulated pile foundations are limited, and the set defects cannot be changed. For large-scale examinations or assessments, subsequent students may be based on the previous students' examinations. The defect waveform brought out at the end can pass the test easily, and it cannot meet the theoretical analysis level of the tested students on the measured defects
