Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, the purpose is only to better understand the content of the present invention, and the examples given are not intended to limit the protection scope of the present invention.

[0030] see figure 1 , figure 2 , a pipe-soil model test device under the influence of site subsidence and faults, comprising a fixed box 2, a vertically movable box 3, and a horizontally moved box 4 arranged in sequence, and the soil in the three boxes is organically combined Overall, the test pipe runs through three boxes.

[0031] In this embodiment, there are three test pipes running through the fixed box 2, the vertically movable box 3, and the horizontally moved box 4, and the three test pipes are set up at two different heights. Three holes 27 (see Figure 8 ). Setting up the three test pipes at two different heights can reduce the interaction force between the pipes, sa...

Abstract

The invention relates to a pipe-soil model tester for use under impact of site settlement and faulting, comprising a fixed box, a vertical moving box and a horizontal moving box arranged in order. Soil in the three boxes is an organically combined whole. A test pipe penetrates the three boxes. The fixed box is welded or anchored to a fixed table. The vertical moving box is disposed on a temporary support rack. The horizontal moving box is disposed on a line position rail through roller modules mounted at the bottom of the horizontal moving box. A loading portion comprises an MTS power apparatus, a vertical loading jack and a transverse loading jack. The whole structure is fixed on a ground anchor. The tester is capable of simulating the impact of two site environments, namely non-uniform settlement and faulting, upon lines buried in the tester and also capable of simulating the impact of coupling action of the two environments upon mechanical properties of the lines, simulation similarity is satisfied, complex site conditions such as non-uniform settlement and faulting are simplified, indoor testing operations are facilitated, and simulating stress condition of the buried lines is facilitated.

Description

technical field [0001] The invention relates to a test device for the influence of site environment on pipelines, in particular to a test device for a pipe-soil model under the influence of site settlement and faults. Background technique [0002] Underground pipelines are widely used in transporting water, oil and gas, as well as in communication, power supply, transportation and drainage, and have become the main artery of modern industrial production and urban life. Nowadays, the damage of pipelines due to changes in site environment is the main reason. Therefore, understanding the mechanism of pipeline damage caused by site changes has important application value for the research on the safety and reliability of underground pipelines. Most of the existing pipeline system simulation devices under site conditions simulate the influence of a single site environment on pipelines. In an earthquake environment, pipelines are often affected by multiple site conditions, so a dev...
