Shield segment joint anti-penetrability performance test device

Abstract

The invention provides a shield segment joint anti-penetrability performance test device which comprises a high-pressure water supply system, a test bed and a measurement system. The high-pressure water supply system is used for supplying pressure water or liquid. The test bed is used for mounting a test piece, supplying the action space of the pressure water (liquid) and simulating the contact state of a segment joint. The measurement system is used for setting test work station parameters and measuring test process data. The high-pressure water supply system is connected with the test bed through a high pressure resisting hose. The measurement system is executed in the mode of connecting all sensors mounted on the test bed, a recorder and a computer for reading through cables. A shield segment joint anti-penetrability performance test under the aging state of multiple rubber water stopping strips, the contact state of multiple joints and multiple stress states can be achieved, the operation is easy and convenient, and high practicality is achieved. The device can be widely used for the test detection or study for the short-term performance and long-term performance of the rubber water stopping strips under the water environment or the liquid environment.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a device for testing the anti-seepage performance of shield segment joints. Background technique [0002] In shield tunnels, water leakage has always been a prominent problem affecting the safety and normal operation of subway structures. The survey found that most of the water leakage occurred at the joints of the segments, and the anti-seepage of the joints is achieved by installing the upper and lower two It is realized by joint waterstop strips arranged symmetrically. It can be seen that the impermeability and long-term effectiveness of segment joints are crucial to the normal service of shield tunnels. However, the stress state and impermeability mechanism of segment joints are very complicated, and it is difficult to make a breakthrough in theory, so it needs to be determined by experimental methods. Literature search found that there is no relevant test device and equipm...
