Embodiment Construction

[0022] Attached below figure 1 , 2 , 3, 4 describe the present invention in detail:

[0023] An on-line monitoring method for settlement and convergence during building construction and operation

[0024] A reflector 4 is installed at the settlement point of the vault, and the level can be adjusted;

[0025] Laser displacement sensor I1 and laser displacement sensor II2 are installed at the arch waist, and laser displacement sensor III5 is installed vertically below the settlement point;

[0026] Wherein the laser displacement sensor I1 at the arch waist emits laser upwards and intersects the laser emitted by the vertically placed laser displacement sensor III5 at a point on the reflector;

[0027] Laser displacement sensor II2 at the arch waist horizontally emits laser light and intersects horizontally with vertically placed laser displacement sensor III5;

[0028] Record the lengths of sides AB and AC of the triangle. Remove the laser displacement sensor III5 and enter ...

Abstract

The invention relates to an on-line monitoring method for settlement and convergence in building construction and operation periods, in particular relates to a laser displacement sensor-based on-line monitoring method for the settlement and the convergence in a construction process and an operation period of vault crowns and haunches of tunnel and subway buildings, and belongs to the fields of building and highway engineering, and applied to the industry of structural safety and health monitoring. The online monitoring method disclosed by the invention can be used for solving problems of complex installation, expensive equipment, great outside influence on the structure, high requirement on installation and using environments and the like in known methods for on-line monitoring of the vault crown settlement of tunnels and subways in construction and operation periods.

Description

technical field [0001] The invention relates to an online monitoring method for settlement and convergence during building construction and operation period, in particular to an online monitoring method for settlement and convergence during the construction process and operation period of tunnels, subway building vaults and arch waists based on laser displacement sensors. monitoring method. It belongs to the field of construction and highway engineering, and is used in the structural safety and health monitoring industry. Background technique [0002] Currently known methods for on-line monitoring of tunnel and subway vault settlement during the construction period and operation period all have problems such as complicated installation, expensive equipment, large structure affected by the outside world, and high requirements for the installation and use environment. Contents of the invention [0003] In order to overcome the above-mentioned defects, the object of the pres...
