Description

An intelligent monitoring and early warning device for geotechnical engineering slopes

technical field

The invention relates to the field of monitoring and early warning equipment, in particular to an intelligent monitoring and early warning device for geotechnical engineering slopes.

Background technique

Geotechnical engineering is a new technical system established in the practice of civil engineering in European and American countries in the 1960s. Geotechnical engineering is to solve rock mass and soil engineering problems, including slope and foundation, slope and underground Engineering and other issues as their own research objects;

In recent years, with the rapid development of my country's economy, roads, railways, rivers and other projects in cities have been built, and have gradually become the main arteries of urban people's travel and living environment. With the establishment of various buildings, the composition of rock and soil becomes complex, resulting in serious soil erosion and frequent landslides, seriously affecting people's lives and safety. At present, engineering slope protection and ecological slope protection are mainly used in slope management. Engineering slope protection often adopts stone or concrete retaining walls and face protection, or adopts lattice protection, anchor spraying support, which can overcome serious water and soil erosion, landslides, debris flows and other disasters caused by slopes, but it also brings serious damage. Environmental problems, such as ecological imbalance; factors such as landslides, sideslips, and collapses of slopes are the main disastrous factors for slope damage. At present, anchoring technology is widely used in domestic construction of roads, railways, foundation pits, and open-pit mines. To strengthen the rock and soil slope, there are usually two ways to strengthen the rock slope, one is superficial reinforcement, and the other is deep reinforcement. The main methods of surface fixation are hanging protective net, shotcrete, anchor rod, For frame beams, etc., the main method of deep reinforcement is anchor cables. For slope reinforcement projects that require a higher level of slope safety, it is necessary to solve the superficial stability and deep stability of the slope at the same time or alternately carry out the two fixing methods.

Existing monitoring methods mainly include buried sensors, levels, total stations, and three-dimensional scanning. Among them, buried sensors are limited by the service life of the sensors and the buried range, and can only be used for short-term settlement monitoring after construction. Suitable for long-term performance tracking of facilities where full line coverage is not possible. At the same time, there are mainly two ways to bury the sensor. One is to bury the sensor directly in the slope, and the sensor will move due to the movement of the soil layer in the slope, which will affect the detection accuracy. The other is to set the sensor in the profile tube, which is buried in the roadbed. Since the profile tube will bend with the settlement of the slope, the position of the sensor in the profile tube will also change, which also affects the Detection accuracy. Since the level instrument is mainly manual detection, there are certain safety risks on the slope due to the slope problem, and the detection takes a long time. The total station or the total station with three-dimensional scanning function is usually set at a fixed surveying point, and it is necessary to ensure that all detection positions are covered in its field of view. However, due to the slope of the slope, the detection method has certain limitations. This will affect the effectiveness and reliability of the overall monitoring and early warning.

For this reason, an intelligent monitoring and early warning device for geotechnical engineering slopes is proposed.
