Anchoring devices for mounting reticulate catchers on rocky sections of roads

Abstract

This paper discusses an important aspect of ensuring safety during construction work at height, as well as when installing protective elements that catch possible falling parts of the terrain, when it is adjacent to the roadway and other communication routes. The purpose of the field tests was to verify the stability of products on the terrain with the application of static and dynamic loads. The stability test was carried out during installation on different rocks and also different regions of the CIS countries. Dynamic tests simulating cargo stall at various factors, followed by researching the ways to stop the falls. Static tests were carried out using manual tension systems - tackles. Tests in the laboratory were carried out in order to determine the destructive load on the product. For this, a special test mold was made that simulated the natural conditions. All tests were carried out using anchoring devices of various sizes, as well as with different options for the installation depth and support of the anchor. During the tests, a number of features based on the design form were discovered. The results of laboratory tests are displayed in the table with data for all test samples. A comparison was made of the bearing characteristics. As a result of this work, both the positive and the negative aspects were identified, it was especially important that the question arose of the need to possess the necessary competencies for installing this type of device.
