A real-time monitoring method for deep underground soil displacement

Abstract

The invention relates to the field of underground construction monitoring, and particularly relates to a real-time monitoring method for displacement of an underground deep-layer soil body. The real-time monitoring method comprises the following steps of: burying an inclination measuring pipe at the position under the surface of the existing building, distributing a plurality of inclinometer probes in the inclination measuring pipe, and connecting the plurality of inclinometer probes together by cables; then statically monitoring settlement displacement data at the position in real time by utilizing all the inclinometer probes, sending the data to a computer on the ground by a cable, carrying out data processing, and obtaining settlement information. The real-time monitoring method has the advantages that the settlement of the underground deep-layer soil body of the building along the vertical direction in construction is effectively monitored, the real-time static monitoring area is large, the accuracy of measured data is high, the labor cost for dynamic monitoring is reduced, and a solid foundation is laid for construction design, progress scheduling and avoiding measures and the like.

Description

technical field [0001] The invention relates to the field of underground construction monitoring, in particular to a real-time monitoring method for deep underground soil displacement. Background technique [0002] When the underground construction passes through the structure, it will inevitably disturb the soil. The multi-storey residential or public buildings with natural foundations have poor structural integrity. risk event. Therefore, it is very important to monitor the corresponding underground soil changes when studying the micro-disturbance technology of shield tunneling through buildings (structures), which is a hot issue in the development of underground space and rail transit construction. [0003] For various methods used in settlement monitoring, such as single pile settlement analysis, pile group settlement analysis, etc., this method is likely to lead to large errors. Embedded inclinometer tubes are also used to measure settlement. For example, during highw...

Problems solved by technology

This dynamic measurement method not only requires a lot of manpower to manually operate the probe sensor, but also during the operation, due to the deviation of the sensor, the wear of the pulley and the deviation of the positioning of the probe sensor, it is difficult to monitor more accurate data, and in In this monitoring area, the settlement data is measured manually, which is inefficient, and it is impossible to obtain real-time and the soil settlement of the entire monitoring area at the same time
