Description

A kind of circular tunnel cuts driving experimental provision entirely
Technical field
This utility model relates to similarity simulation experiment tunnelling apparatus field, particularly relates to a kind of circular tunnel and entirely cuts driving in fact Experiment device.
Background technology
In underground mining tunnelling, tunnel underground digging process, pledge excavation will make country rock lose original poised state, Its internal original stress field changes.If the stress in the new stress field of country rock is not above the bearing capacity of rock, rock is just Can balance voluntarily;Otherwise country rock will it may happen that destroy, as occurred rupturing, roof fall or section produce large deformation.Therefore, lane The research of road surrounding rock stability is for producing actual having great importance.At present except using theory analysis, field observation, soft Outside part analogy method, similarity simulation experiment is also a kind of strong scientific research means.Similarity simulation experiment is based on similar fixed Rule, uses similar materials to simulate the physical simulation experiment of the problems such as mine, ground, geology.By occur on model Phenomenon and rule, draw relevant technical specification and parameter, thus make guidance for theoretical research and field practice.
At present in similarity simulation experiment, the driving of circular tunnel uses simple cutter more, carrys out Pork-pieces excavation rock by pocket knife Body.This original driving method not only wastes time and energy, excavation effect is undesirable, and actual with scene does not corresponds, have impact on The accuracy of similarity simulation experiment.
Utility model content
The purpose of this utility model is to provide a kind of circular tunnel entirely to cut driving experimental provision, in order to solve in background technology Problem.
To achieve these goals, the technical scheme that this utility model is used is:
A kind of circular tunnel cuts driving experimental provision, entirely including cutting part, drive division, connecting shaft, rotation section and sleeve pipe.Institute State cutting part and include spiral bit, annular tooth mouth cutting knife.Described drive division be surrounding be the cylinder of screw thread, can in be threaded onto sleeve pipe; Described cylinder, one end is provided with rectangular recess and circular groove, and the other end is connected with connecting shaft by bolt.Described connecting shaft is Straight-bar, described rotation section is right angle bull stick, and both are bolted.The rectangle that described spiral bit is securable to drive division is recessed Groove;Described annular tooth mouth cutting knife is securable to the circular groove of drive division.Screw thread is set in described sleeve pipe, supporting with drive division.
Preferably, described spiral bit includes fluted drill body and cylindrical handle body;The diameter of described fluted drill body has multiple;Described circle Post handle body periphery is provided with two incisal planes, is securable to the rectangular recess of drive division.
Preferably, described a kind of circular tunnel cuts driving experimental provision entirely, it is characterised in that described annular tooth mouth cutting knife Diameter, more than the diameter of spiral bit, has certain gap between annular tooth mouth cutting knife and spiral bit.
Further, described a kind of circular tunnel cuts driving experimental provision entirely, including following operating procedure:
A. on similarity simulation experiment platform, determine that circular tunnel excavates position, spiral bit is directed at tunnel central point;
B. manual rotation right angle bull stick, spiral bit incision rock mass;
C., after spiral bit pierces rock mass certain depth, annular tooth mouth cutting knife comes into contact with rock mass;
D. the landwaste cut falls into the gap between spiral bit and annular tooth mouth cutting knife, extracts mole after landwaste is filled, Pour out landwaste.
Technique scheme is used to provide the benefit that:
Technical solutions of the utility model use a kind of circular tunnel entirely to cut driving experimental provision, drive Flos Cannabis by shake bull stick Drill bit and annular tooth mouth cutting knife carry out the excavation of similarity simulation experiment circular tunnel, can arrive disposable full advance, enclose The smooth purpose without residue of rock.Additionally, this utility model cost is low, reasonable in design, simple in construction, manipulation simplicity, degree of accuracy High, it is adaptable to similarity simulation experiment circular tunnel entirely cut excavation.

Detailed description of the invention
For making the purpose of this utility model, feature and advantage definitely, with embodiment, this utility model is carried below in conjunction with the accompanying drawings A kind of circular tunnel of confession entirely cuts driving experimental provision and is described in detail.
As shown in figs 1-9, a kind of circular tunnel cuts driving experimental provision entirely, including cutting part 1, drive division 2, connecting shaft 3, Rotation section 4 and sleeve pipe 5.Described cutting part 1 includes spiral bit 6, annular tooth mouth cutting knife 7.Described drive division 2 is that surrounding is The cylinder of screw thread, can in be threaded onto sleeve pipe 5;Described cylinder, one end is provided with rectangular recess 8 and circular groove 9, and the other end leads to Cross bolt to connect with connecting shaft 3.Described connecting shaft 3 is straight-bar, and described rotation section 4 is right angle bull stick, and both are by bolt even Connect.Described spiral bit 6 is securable to the rectangular recess 8 of drive division 2;Described annular tooth mouth cutting knife 7 is securable to drive division 2 Circular groove 9.Screw thread is set in described sleeve pipe 5, supporting with drive division 4.
Described spiral bit 6, annular tooth mouth cutting knife 7, connecting rod, bolt etc. are equipment of the prior art, this utility model It is only they to be used and combines, it is repeated no more.
As shown in Fig. 2,5,6, in this utility model, described spiral bit 6 includes fluted drill body 10 and cylindrical handle body 11; The diameter of described fluted drill body 10 has multiple;Described cylindrical handle body 11 periphery is provided with two incisal planes, is securable to drive division 2 Rectangular recess 8.
As Figure 1-4, in this utility model, the diameter of described annular tooth mouth cutting knife 7 is more than the diameter of spiral bit 6, ring Between shape tooth mouth cutting knife 7 and spiral bit 6, there is certain gap.
Embodiment of the present utility model is as follows:
On similarity simulation experiment platform, arrange scale model according to the actual geological conditions such as mine, ground, assemble and check this circle lane Road cuts driving experimental provision entirely.Scale model determining, circular tunnel excavates position, spiral bit is directed at tunnel central point. Manual rotation right angle bull stick, spiral bit incision rock mass.After spiral bit pierces rock mass certain depth, annular tooth mouth cutting knife starts Contact rock mass.The landwaste of cutting falls into the gap between spiral bit and annular tooth mouth cutting knife, extracts driving dress after landwaste is filled Put, pour out landwaste.Repeat this process, until roadway excavation terminates.
As it has been described above, embodiment of the present utility model is explained, it is only intended to help elaboration of the present utility model Core concept and technical scheme, not limit it.This utility model is only by claims and four corner thereof and equivalent Limiting, every insubstantial made according to this utility model is replaced, is deformed and improve, and is all contained in protection of the present utility model Within the scope of.
