Horizontal foundation pit supporting system

Abstract

The invention discloses a horizontal foundation pit supporting system. The horizontal foundation pit supporting system comprises supporting rods and further comprises axial force monitoring and compensating devices, a hydraulic system and a control system. The axial force monitoring and compensating devices are arranged at the top ends of the supporting rods. Sensors are arranged at the corresponding positions of the axial force monitoring and compensating devices. The sensors are connected with the control system through signal lines. The hydraulic system is connected with the control system and the axial force monitoring and compensating devices. The horizontal foundation pit supporting system is wide in data collection point distribution, capable of collecting data in real time and is high in accuracy, and remote monitoring of the horizontal foundation pit supporting system is achieved.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a foundation pit horizontal support system. Background technique [0002] With the continuous improvement of social civilization, the emergence of large cities and super-large cities has accelerated the development needs of urban rail transit and super high-rise buildings. There are more and more deep foundation pit projects, and the positions between buildings are getting closer As it gets closer, the impact of engineering construction is getting bigger and bigger, reaching the situation of "one part mobilizes the whole body". Deep foundation pit construction must first consider the safety of the foundation pit. The construction of deep foundation pits is accompanied by strong environmental effects. If the deformation control of deep foundation pits cannot be effectively dealt with, it will easily affect its normal use, and even cause catastrophic accidents in severe cases. ...

Problems solved by technology

[0006] 2. Each point of the monitoring data is measured by an inclinometer tube, and only one point can be measured at the vertical height. However, the overall wall surface is wide, and different force deformations will occur when the force on each point of the wall is different. prone to misjudgment

[0007] 3. The instrument uses the same sensor when using data, and the accuracy of the instrument itself directly affects the accuracy of the monitoring data of the entire foundation pit.

[0008] 4. The data sampling is delayed. Due to the time difference between data sampling, calculation and transmission, corresponding remedial measures can only be implemented after the foundation pit is deformed, and data cannot be collected in real time.

[0009] 5. The existing part of the foundation pit horizontal support system can only measure the axial force of the support rods on both sides of the wall, and cannot detect the displacement of each side wall at all, which will also cause displacement of the protective body outside the foundation pit , and a foundation pit accident occurred
