Description

Excavation engineering side slope is from early warning reinforced structure

Technical Field

The invention relates to the technical field of excavation engineering, in particular to a self-warning reinforcement structure for a side slope of excavation engineering.

Background

The earth excavation is a key process from the initial stage of engineering to the construction process. The soil and rock are loosened, crushed, excavated and transported out. According to the properties of rock and soil, the earth and stone excavation is divided into earth excavation and stone excavation.

Earth excavation is classified into open excavation, tunnel excavation and underwater excavation according to the construction environment, i.e., open excavation, underground excavation or underwater excavation. In water conservancy projects, earth excavation is widely applied to site leveling and slope cutting, foundation excavation of hydraulic buildings (floodgates, dams, spillways, hydropower station plants, pump station buildings and the like), excavation of underground caverns (hydraulic tunnels, underground plants, various flat holes, vertical shafts and inclined shafts), excavation and dredging of river channels, channels and ports, exploitation of filling materials, building stones and concrete aggregates, removal of temporary buildings such as cofferdams or the like or masonry, concrete structures and the like.

In the excavation process, due to the fact that collapse easily occurs due to the fact that geological environments are different, not only can engineering progress be affected, but also safety of equipment and people is threatened, strengthening measures are often taken for the side slope in the prior art, however, the early warning function is lacked, the side slope is difficult to find and remedy in time when collapse occurs, the side slope is inevitably cracked and separated before collapse, and therefore the situation that measures can be taken to save can be found in time in the period of time.
