Field simple assembly ultralong static load reference beam

Abstract

The invention discloses a field simple assembly ultralong static load reference beam, comprising two beam bodies which are arranged in parallel, wherein length of each beam body is 12m at least, and a set position of a reference pile bearing the beam bodies can meet design requirements; each beam body is formed by abutting and assembling multiple splicing beams, namely the splicing beams are connected by virtue of a detachable connecting structure; and each splicing beam adopts an H-shaped I steel, and the upper flange, the lower flange and the web plate of the H-shaped I steel are respectively correspondingly connected by virtue of bolt connecting structures. According to the field simple assembly ultralong static load reference beam, the length of each beam body is determined by the set position of the reference pile, and the set position of the reference pile meets the design requirements, namely displacement of the reference pile is not required to be monitored at the moment, so that secondary observation is avoided, the reference pile is far away from a pier, a long enough distance is kept with a tested pile, and accuracy of test data of a pile foundation is guaranteed. The field simple assembly ultralong static load reference beam disclosed by the invention is simple in structure, simple and feasible, splicing can be completed on the scene quickly, working efficiency is higher, and stability is good.

Description

Technical field [0001] The invention belongs to the technical field of construction engineering pile foundation detection, and in particular relates to an on-site simple assembly type ultra-long static load reference beam. Background technique [0002] The vertical static load test of pile foundation is the most intuitive and reliable method to determine the bearing capacity of pile foundation. In the vertical static load test of the foundation pile, the effect of the buttress load on the foundation soil will cause the deformation of the reference point, that is, the reference pile will rise or sink with the vertical displacement of the foundation soil and be placed on the reference pile The reference beam will also move up or down with the reference pile. Since the dial gauge for detecting the displacement of the inspected pile is installed on the reference beam, the displacement of the reference beam will directly affect the accuracy of the test result of the inspected pile.

AI Technical Summary

Problems solved by technology

However, the disadvantages of this method are: (1) Use the data obtained from the secondary observation to correct the displacement data of the tested pile foundation. Since there is no unified correction method, the uncertainty of the entire reference system increases, and the obtained correction data may have some problems. Large error; (2) When using a level gauge for secondary observation, there are great difficulties in the installation and observation of the leveling rod, which is easy to cause errors in the secondary observation data
