Abstract

The invention relates to the field of shield tunnel segment detection, aims at detecting the stress performance and the ultimate bearing capacity of the segment, and provides a segment mechanical test device which comprises a main framework, mutual pull mechanisms, a supporting roll disc and load loading mechanisms. The main framework comprises a rectangular framework structure and an installing plate of which the installing surface is provided with locating clamp grooves. The locating mutual pull beam and the adjusting mutual pull beam of each mutual pull mechanism are mutually parallel. The locating ends of mutual pull rolls are fixedly connected with the locating mutual pull beam, and the adjusting ends are flexibly connected with the adjusting mutual pull beam. Each load loading mechanism comprises a loading mechanism and an installing baseplate which is provided with a locating key stand. The segment to be detected is arranged in the main framework in detection, the mutual pull mechanisms sleeve the main framework and are close to the end part of the segment to be detected. The load loading mechanisms are installed and fixed on the installing plate and abut against the segment to be detected. According to the segment mechanical test device, the stress performance and the ultimate bearing capacity of the segment to be detected can be directly detected so that detection is convenient and the accuracy is high.

Description

technical field [0001] The invention relates to the field of detection of shield tunnel segments, in particular to a test device for mechanical test detection of shield tunnel segments. Background technique [0002] In tunnel engineering, due to the large size of the segment and the variety of structural types, the mechanical properties of the segment, that is, the force mechanism, cannot be directly detected when testing the mechanical properties of the segment. At present, the commonly used detection method is to first make a segment model according to the size and structure of the segment, and the structure of the segment model is the same as that of the segment, and the size of the segment model is reduced in proportion to the segment; The model is subjected to mechanical tests to detect the various data and performance of the segment model; finally, the various data and performance of the segment are calculated according to the data and performance of the segment model....
