A method for monitoring and compensating the axial force of foundation pit

Abstract

The invention discloses a foundation pit axial force monitoring and compensation method, which comprises the following steps: installing a sensor on an axial force monitoring and compensating device in a foundation pit horizontal support system, the axial force monitoring and compensating device being installed on the top of a support rod, The sensor is used to collect raw data on site in real time and transmit the data to the control system; the control system receives and processes the data, and the control system is connected to the sensor through a signal line; When the axial force exceeds the set value, the control system instructs the axial force monitoring and compensating device to perform compensation, and the axial force monitoring and compensating device is connected to the control system through a signal line. The method for monitoring and compensating the axial force of foundation pit provided by the invention has wide distribution of data collection points, real-time data collection, high accuracy rate, and ensures the safety of foundation pit construction.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a method for monitoring and compensating the axial force of a foundation pit. Background technique [0002] With the continuous improvement of social civilization, the aggregation effect of human beings, the continuous emergence of large cities and super-large cities, thus accelerating the development needs of urban rail transit and super high-rise buildings, more and more deep foundation pit projects, and construction The positions between objects are getting closer and closer, and the impact of engineering construction is getting bigger and bigger, reaching the situation of "pulling one to mobilize 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...

Problems solved by technology

[0005] 1. The monitoring points are distributed on important points of concern. Due to cost and construction reasons, they are not fully distributed, and it is difficult to ensure that the monitoring points are the most important points due to the unpredictable changes in underground soil pressure.

[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.
