as the main means of informatization construction, arises at the historic moment of the foundation pit monitoring technology in recent years, not only effectively prevent the accidents during foundation pit construction, the construction project cost control at the same time Watson Wchangeorganisation system played an important role. Today, the small make up to you to introduce the construction of Angle sensor in the application of the foundation pit monitoring technology.

& have spent

To maintain the structure of the foundation pit monitoring method mainly has the following two kinds:

1 Angle sensor monitoring

Use high precision obliquity sensor, gathers the tilt data of the key parts supporting pile precision reflect the supporting pile tilt value change, once found change overrun, can provide early warning in time, ensure the security of the supporting pile structure itself.

2. Total station measuring
Using 2 s high precision total station, combined with excellent effect of reflection to the leica reflector plate, ensure the side coordinates of each point effectively, and can reflect the retaining piles of coordinate of observation points, thus supporting pile top displacement through calculus.


By total station and obliquity sensor, can accurate measure supporting pile of pile deformation and relative supporting pile tilt changes, effectively protect the safety of the supporting pile.

In order to ensure the maintenance of the structure of the deformation information, using the Angle sensor and the method of total station synchronous monitoring mutual authentication. HuBiZhuang recent changes in displacement, monitoring data and retaining pile top change value is about 7 mm.
By using the Angle sensor and total station, the monitoring data. This method reveals the structure of the safety status and safety margin, for follow-up to provide scientific basis for the establishment of construction scheme and construction order, from the Angle of construction cost control can avoid blind waste and reduce the construction hazards may cause of accidents and economic losses.
