Anti-slide pile-anchor cable connecting device suitable for side slope model test

Abstract

The invention discloses an anti-slide pile-anchor cable connecting device suitable for a side slope model test. The anti-slide pile-anchor cable connecting device is used for connecting an anti-slidepile and an anchor cable with one end penetrating through the anti-slide pile, and comprises a first fastening device, a second fastening piece and a third fastening piece, wherein the first fasteningdevice is connected to the anti-slide pile; the second fastening piece is connected to one end of the anchor cable; and the third fastening device is connected into the second fastening device in anembedding mode. The first fastening device is fixedly connected to the anti-slide pile through a plurality of first fastening pieces. The end, connected with the second fastening piece, of the anchorcable penetrates through the anti-slide pile. The outer side of the third fastening piece is connected in the first fastening device in an embedding mode, and the inner side of the third fastening piece is connected in the second fastening piece in an embedding mode. By adjusting the embedding depth of the third fastening piece in the first fastening device, different prestresses are applied to the anchor cable. According to the anti-slide pile-anchor cable connecting device, the connection depth of the anchor cable and the anti-slide pile can be adjusted, and the prestress applied to the anchor cable can be accurately adjusted, so that the connection effect is greatly enhanced, the effectiveness of the applied prestresses is improved, the test period is shortened, the test difficulty is reduced, and the precision of the model test is improved.

Description

technical field [0001] The invention relates to the technical field of geological disaster model tests, in particular to an anti-slide pile-anchor cable connection device suitable for slope model tests. Background technique [0002] Due to the frequent occurrence of landslide geological disasters and the wide range involved, it brings great inconvenience to the landslide investigation work. Therefore, the slope model test is more and more used in the field of slope analysis. When using the slope model test device to simulate the solid slope, it is also necessary to simulate the solid reinforcement structure existing in the slope. At present, prestressed anchor cable anti-slide piles (commonly known as anchor piles) are more and more used as one of the measures to strengthen slopes because of their ability to fully utilize the strength and bearing capacity of rock mass itself. [0003] When simulating the prestressed anchor cable anti-slide pile in the slope model test, due ...

AI Technical Summary

Problems solved by technology

[0003] When simulating the prestressed anchor cable anti-slide pile in the slope model test, due to the limitation of technical means, the way of directly connecting the anti-slide pile material and the anchor cable material is usually used to simulate the connection state of the anti-slide pile and the anchor cable. Therefore, the anti-slide pile-anchor cable system is formed to achieve the effect of strengthening the slope, but this method cannot determine the real prestress value after the prestress is lost due to various reasons, so further adjustments to the test device are required; The method of directly connecting the anti-slide pile material and the anchor cable material makes it impossible to dynamically adjust the prestress applied to the anchor cable, which will cause the results of the model test to be inconsistent with the real situation and affect the accuracy of the test results; at the same time, it cannot meet the test requirements. Purpose of Diversity Discussion

[0004] In order to change this test situation, it is necessary to make a connecting device between the anti-slide pile and the anchor cable that can effectively and accurately adjust the prestress size to meet the requirements of different prestress sizes in the model, which will inevitably prolong the test period and increase the difficulty of the test. Increased trial costs
