Drilling orifice protective device.
Background technology
With the increasingly propulsion of China's large-scale basis Facilities Construction and deep resource energy extraction, occur a series of
Underground rock project, such as traffic tunnel, water power underground power house, paint storage storehouse, mine working.These engineerings are reliably obtained to open
It is guarantee engineering safety and the important step that engineering is promoted to be smoothed out to dig with the mechanical response of the rock mass in operational process, is needed therefore
It constructs substantial amounts of drilling, implements the test to multi-parameters such as rock mass deformation, rupture, stress.Testing bore holes generally have two classes, and one
Class is open-hole, i.e. probing is completed to be always maintained at naked state in metapore, enters drilling follow-on test for later stage test probe；It is another
Class is plugging hole, and test sensor device is put into design position in hole, and entire drilling is blocked by slip casting.Due to subsurface rock
Engineering local environment is severe, and execution conditions are complicated, and open-hole and untreated plugging hole are highly susceptible to destroy.
On the one hand, the excavation of underground engineering constantly changes deformation and the stress condition inside rock mass.Especially in deep
Under the condition of high ground stress of underground, rock mass easily occur local stress release so that testing bore holes damage zone content it is easy to crack and in response to
Power type rubble peels off and plug-hole occurs, and this phenomenon is in the particularly collection showed in the range of 0~60cm of aperture and apparent；
On the other hand, after being completed due to Underground Engineering Excavation, the excavation face of tunnel is also needed to carry out gunite concrete, hangs bar-mat reinforcement
With the constructions such as lining cutting, in addition the execution conditions of underground are quite severe, frequently appear in drilling be placed around sign board can not be by
It was found that the phenomenon that.In addition on-site construction processes are complicated, and convergence time is compact so that construction personnel is difficult to be taken into account while construction
Protection work to drilling, therefore drill easily by anchor spraying concrete either lining construction closure or destruction.
To solve the above-mentioned problems, traditional way is utilized in drilling and fills in taper wooden stick, geotechnique at the construction field (site)
Pvc pipe similar in cloth or aperture.The defects of this method, is：On the one hand, due to tunnel gunite concrete or the covering of lining cutting
Face is big or can't see the position of drilling at all, and aperture blocks the part that object or device are stretched out outside hole and easily sprayed by concrete
And be difficult to loosen, it is necessary to chisel firm concrete again when being tested in hole, work difficulty is big, but also to drilling orifice
Cause certain artificial destruction；On the other hand, taper wooden stick, geotechnological woven fabric and pvc pipe are close to hole wall and fill in length in hole
It is shorter, it is general no more than 20cm, otherwise since palisades inlay too tightly frictional resistance increase, cause to extract and plugging hole
Mouthful so that drilling thoroughly failure, in this case, this method not only cannot effectively protect underground rock project to test aperture
The concentration lesion ruptures area of 60cm scopes, the also additional workload added before test.
