Recoverable framed bent system for rock-soil body in-situ mechanical test and use method of recoverable framed bent system

Abstract

The invention relates to the field of rock and soil mechanics equipment, in particular to a recoverable bent frame system for rock and soil mass in-situ mechanical tests, which is characterized in that a conveying track in a conveying system is arranged along the length direction of a supporting structure, two ends of a conveying frame beam are mounted on the conveying track through conveying pulleys, and the extending direction of the conveying frame beam is the width direction of the supporting structure; the hoisting tackle and the hoisting unit are installed on the conveying frame beam and can hoist and move samples and equipment, and angular point displacement sensors in the detection system are arranged at corners of a rectangular frame at the top of the supporting structure and used for assisting in leveling the supporting structure and monitoring displacement deformation of the supporting structure. The main beam stress sensor is arranged on the conveying frame beam and used for monitoring the stress of the conveying frame beam. The framed bent system is reasonable in structural design and suitable for various rock-soil body in-situ mechanical tests, the structure can be expanded according to needs, and the framed bent system can be recycled for multiple times. The invention further provides a using method of the framed bent system.

Description

technical field [0001] The invention relates to the field of rock and soil mechanics equipment, in particular to a recyclable bent frame system for in-situ mechanical tests of rock and soil bodies and a use method. Background technique [0002] The in-situ test of rock and soil mass is an indispensable test method in large-scale projects because the test body is larger than the indoor sample, which can contain the changes of macroscopic structure and the test conditions can be close to the actual situation. Most in-situ tests need to provide reaction forces to simulate building loads. The counter-force ground beams are usually built manually with bricks. After the masonry is completed, the ground beams are maintained and waited for the strength to meet the design requirements. The whole process is time-consuming, labor-intensive and costly. Once the ground beam structure is formed, it cannot be modified and expanded, and the test content is limited. Due to the limitation o...

AI Technical Summary

Problems solved by technology

Reaction ground beams are usually built manually with bricks. After the masonry is completed, the ground beams are maintained until the strength meets the design requirements. The whole process is time-consuming, laborious and expensive.

Once the ground beam structure is formed, it cannot be modified and expanded, and the test content is limited

Due to the limitations of material deformation and masonry level, the state of the ground beam cannot be detected during the test

After the test is completed, the ground beams cannot be recycled and are usually discarded in situ or pulled down for cleaning

[0003] There are many problems in the in-situ test of the masonry method, such as the inability to test immediately, the structure cannot be modified, the state of the structure is uncontrollable, and waste is caused by one-time use.
