Description
Technical field
The present invention relates to a kind of underground engineering monitoring measurement device, specifically, is related to a kind of based on total powerstation method
Underground engineering Vault settlement measuring equipment.
Background technology
The underground engineerings such as tunnel, tunnel, mountain ridge cave depot, due to its construction disguise, the complexity of geology, construction it is more
The polytropy of sample and environment, cause difficulty of construction big, chip off-falling and the security incident such as cave in easily occurs, not only severely impacts
Engineering construction progress, also greatly threaten the life security of workmen.Monitoring measurement refers in underground engineering construction mistake
To country rock, earth's surface, the deformation of supporting construction and stable state, and the current observation and amount of surrounding enviroment dynamic progress in journey
Survey work.By monitoring measurement it will be seen that and grasp country rock stable state and supporting structure system the degree of reliability, really
Protect construction safety and supporting construction is stable, to change Grades of Surrounding Rock, adjustment preliminary bracing and secondary lining parameter in construction, instructing
Sequence of construction, amendment and optimization design provide foundation, and the safety monitoring tool to underground engineering construction is of great significance.
Tunnel vault settlement measurement is one of main contents of underground engineering monitoring measurement, and its measurement apparatus mainly has level
Instrument, convergence gauge, total powerstation etc., compared with spirit level, convergence gauge, total powerstation has high precision, testing convenience, data transfer convenient
The advantages that, it is the most frequently used instrument of tunnel vault settlement measurement.For the underground engineering Vault settlement measurement of total powerstation method,
Because keystone is higher, the reason such as difficult in maintenance, single prism can not be set up at vault, therefore generally pasted using in measuring point
The method of reflection plaster measures.
The conventional measuring point of patch reflection plaster buries step：First, steel plate is welded on reinforcing bar, is fabricated to measuring point；Then,
It is fixed using insertion reinforcing bar after drill hole of drilling machine and using Anchor Agent；, in time will be reflective after the completion for the treatment of just branch concrete ejection
Patch is pasted on steel plate, it is ensured that firm pasting is reliable.
Some deficiency during above-mentioned measuring point is embedded be present：
1. it is poor to go deep into country rock inner wall tightening effect using reinforcing bar, once wall rock loosening, will directly affect test result and prolongs
Continuous property；
2. reflection plaster is pasted in high-altitude, operation difficulty is big, and operator safety is difficult to ensure that, and effect is not easy to confirm；
3. reflection plaster can not avoid engineering construction from polluting and destroy to caused by it after pasting, can not recover automatically to first again
Beginning state, replacing is also extremely inconvenient, and therefore, the continuity and accuracy of measurement data are very low；
4. measuring point can not be reused, measurement cost is high using welding manner connection reinforcing bar and steel plate after fixed；
5. after the completion of preliminary bracing construction, set up that the enforcement difficulty of monitoring stations is very big, the later stage adjusts the flexibility of measuring point
It is very poor.
The content of the invention
In order to overcome the above-mentioned problems in the prior art, the invention provides a kind of underground work based on total powerstation method
