Description
Technical field
The present invention relates to drilling equipment technical field, particularly a kind of underground rock project testing bore holes orifice protecting device adapting to different pore size.
Background technology
Along with the propelling day by day of China's large-scale basis Facilities Construction and deep resource energy extraction, there is a series of underground rock project, as traffic tunnel, water power underground power house, paint storage storehouse, mine working etc.Mechanical response of the rock mass in these engineering excavations of reliable acquisition and running ensures engineering safety and promotes the important step that engineering carries out smoothly, needs a large amount of boring of constructing for this reason, implement rock mass deformation, break, the test of the multi-parameter such as stress.Testing bore holes generally has two classes, and a class is open-hole, has namely drilled in metapore and has kept naked state always, enters boring follow-on test for later stage test probe; Another kind of is plugging hole, and testing sensor device is put into hole design attitude, by the whole boring of slip casting shutoff.Bad environments residing for underground rock project, execution conditions are complicated, and open-hole and untreated plugging hole are very easy to be damaged.
On the one hand, the excavation of underground construction constantly changes distortion and the stress condition of rock mass inside.Especially under the condition of high ground stress of underground, deep, easily there is local stress release in rock mass, make testing bore holes, damage zone content easy to crack peeling off with stress type rubble, plug-hole occur, and this phenomenon is particularly concentrated with obvious what show within the scope of the 0 ~ 60cm of aperture; On the other hand, after Underground Engineering Excavation completes, also need to carry out sprayed mortar, hang the construction such as steel mesh reinforcement and lining cutting to the excavation face of tunnel, add that the execution conditions of underground are quite severe, often appear at the phenomenon that near boring, placement sign board can not be found.On-site construction processes is complicated in addition, and convergence time is compact, makes constructor be difficult to the protection work taken into account while construction boring, therefore holes very easily by anchor spraying concrete or lining construction shutoff or destruction.
In order to solve the problem, way traditional at the construction field (site) adopts to fill in the close pvc pipe in taper wooden stick, geotextiles or aperture in boring.The defect of the method is: on the one hand, due to tunnel sprayed mortar or lining cutting wide coverage or can't see the position of boring at all, aperture blocking object or the device part of stretching out outside hole are easily sprayed by concrete and are difficult to loosen, need will again chisel firm concrete when hole build-in test, work difficulty is large, but also causes certain artificial destruction to drilling orifice; On the other hand; taper wooden stick, geotechnique weave cotton cloth and pvc pipe to be close to the length that hole wall fills in hole shorter; generally can not more than 20cm; otherwise because crag inlays too tightly frictional resistance increase; cause can not extracting and blocking aperture, make to hole and thoroughly lost efficacy, in this case; the method not only can not the concentrated lesion ruptures district of available protecting underground rock project test aperture 60cm scope, also additionally adds the workload before test.
