Description
Technical Field
The utility model belongs to the technical field of the architectural survey construction monitoring, especially, relate to a building space structure relative displacement warp dynamic monitoring device.
Background
At present, the building health monitoring instrument mainly uses the traditional monitoring unit module mode to carry out temporary or long-term detection, and the mode usually adopts the gravity vertical principle to take the building to be monitored as a drop point to carry out the integral inclination measurement of the building or uses the optical principle and other static buildings as drop points to carry out long-distance monitoring on the building under construction. The monitoring unit adopting the gravity vertical principle is usually only suitable for measuring the deformation of the integral inclination angle of the building, and cannot monitor the relative structure in the building. The monitoring unit which adopts the optical principle to carry out displacement deformation on the whole or part of the building structure has harsh use conditions and is firstly seriously restricted by environmental change factors, so that errors are easy to occur in the monitoring and measuring process, the effective implementation scheme of monitoring personnel is misled, especially in a dark and humid environment, the light beam receiving end of the monitoring unit is extremely easy to be damped and damaged, and the light beam transmitting unit can not carry out accurate measurement due to factors such as water mist and the like.
In addition, by adopting manual measurement, a building structure part which cannot be measured by using a precise instrument can be monitored by adopting a manual tracking mode, and the method is clumsy, has high monitoring error and serious insufficient accuracy and increases labor cost. Meanwhile, the deformation of the building part cannot be timely and effectively monitored, and the advance pre-control result is difficult to achieve. Manual measurements therefore react passively substantially after the building has been severely damaged.

Therefore, the project causes serious challenge to the anti-floating capacity of the whole ground reservoir due to the rise of the water level after no artificial precipitation measures are taken; particularly, when the precipitation measures are removed after the backfilling around the ground reservoir is finished, the top plate of the whole ground reservoir cannot be timely and effectively subjected to earthing loading in a short time, so that the bottom plate of the ground reservoir is easy to float, arch, deform and crack due to rising of the water level; meanwhile, the bottom of the structural column is deviated due to arching deformation of the bottom plate, so that the structural column is subjected to chain destructive reactions such as 45-degree oblique fracture of the column body due to brittle failure instantly, and once the quality problems occur, the structural column is a serious quality accident. Because the monitoring position is in the project ground storehouse bottom plate of building, so inside moisture is more, wholly presents dark humid environment to there is ponding phenomenon in the bottom plate upper surface part, and conventional monitoring instrument and unit can't effectively be installed, control, and need set up some control positions very much, lead to the cost to increase obviously.
