Embodiment Construction

[0034] The present invention will be described more fully below using examples. This invention may be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein.

[0035] For ease of description, spatially relative terms such as "upper," "lower," "left," and "right" may be used herein to describe the relationship of one element or feature relative to another element or feature shown in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientatio...

Abstract

The invention discloses a monitoring device for foundation pit deep horizontal displacement and the underground water level. The monitoring device comprises a monitoring module which is formed by detachably assembling a plurality of monitoring units in series. Universal couplings are adopted for mechanical connection between the monitoring units. Electric power and electric signals are all connected through cables with aviation plugs or sockets. According to the monitoring device for the foundation pit deep horizontal displacement and the underground water level, the multiple inclination monitoring units are connected in series, and therefore the monitoring device can adapt to deformation of a monitoring hole and can continuously monitor inclination changes of the monitoring hole for a long time in the monitoring hole. All the monitoring units are connected through spherical joints, the monitoring device can still be sunk into or be pulled out of the monitoring hole freely under the condition that the monitoring hole deforms, the repeated usage rate of the device is increased, and the engineering cost is reduced.

Description

technical field [0001] The invention relates to a monitoring device and method for deep horizontal displacement and groundwater level of a foundation pit, in particular to a monitoring device for automatic measurement of deep horizontal displacement and groundwater level of a foundation pit in the same monitoring hole and the use of the device for measurement Methods. Background technique [0002] With the rapid development of urban construction, there are more and more deep foundation pit construction projects such as urban underground transportation stations, super high-rise buildings, and high-speed railway engineering stations. [0003] During the excavation process of the deep foundation pit, various stresses will cause the displacement of the supporting structure and the deformation of the soil inside and outside the deep foundation pit. The excessive displacement of the supporting structure and the soil supported by the supporting structure will not only endanger the...
