Description

Technical Field

[0001] The utility model relates to the technical field of slope support stress monitoring, in particular to a rock and soil slope support stress monitoring device. Background Art

[0002] Slope support refers to the support, reinforcement and protection measures taken on the slope to ensure the safety of the slope and its environment. Common types of support structures include: gravity retaining wall, buttress retaining wall, cantilever support, plate rib or lattice anchor retaining wall support, pile anchor retaining wall support, anchor spraying support, and slope method; among them, the lattice anchor retaining wall support is composed of reinforced concrete frame and anchor rods. The lattice anchor retaining wall support is a retaining wall that relies on the horizontal tension of the anchor rods anchored in the rock and soil layer to withstand the lateral pressure of the soil. Plants can also be planted in the reinforced concrete frame to strengthen the wall.

[0003] In Chinese patent CN202210309958.3, the present application relates to a device for monitoring stress and deformation of slope support, including several groups of mounting components, several groups of mounting components are respectively installed on the outer periphery of a reinforced concrete frame, several groups of mounting components are installed with elastic parts, several elastic parts are installed with tension sensors, several groups of monitoring line groups are installed on the reinforced concrete frame, several groups of monitoring line groups are fixedly connected to the tension sensors, and the tension sensors are connected to a control center. The present application has a mounting component arranged on the outer periphery of the reinforced concrete frame, which is convenient for installing the tension sensor. When the reinforced concrete frame is deformed, the monitoring line group will move with the deformation of the reinforced concrete frame, and the monitoring line group will involve the tension sensor. When the tension sensor is involved, the information will be transmitted to the control center, so that the deformation of the lattice anchor retaining wall support can be understood in real time, and the deformation of the slope support can be accurately and intuitively monitored.

[0004] Existing rock and soil slope support stress monitoring generally uses video recording or a level to monitor whether the lattice anchor retaining wall support is deformed. However, using video recording or a level requires a long period of monitoring and analysis to know whether the lattice anchor retaining wall support is deformed. Some existing detection devices are equipped with tension sensors to sense changes in tension for detection. However, during the tension detection process, if a heavy object from the outside hits the detection line, it may also trigger the tension sensor, which may cause measurement errors.

[0005] Therefore, in order to solve the above problems, a rock and soil slope support stress monitoring device is proposed. Utility Model Content
