Description
Technical field
The present invention relates to colliery technical field of construction, more particularly to a kind of anti-collapse aperture apparatus and anti-collapse hole construction method.
Background technology
Suspension roof support is the major way of heading supporting, can significantly improve the stress state of roadway surrounding rock, improve branch
Effect, reduction support cost are protected, mitigates before workman works and spends, effective guarantee is provided for safe coal production.Some collieries
Lower exploiting field bottom parking lot can carry out secondary supporting for strengthening supporting intensity to tunnel, require that bottom plate installs anchor during secondary supporting
Bar and anchor cable, in the technological process that anchor cable drills, one of critical process during drilling, and also drilling can not use some existing
Pneumatic hammer and jumbolter, such a bore mode are easy for collapse hole occur in the more tunnel top layer of some poor plasticities, moisture content
Phenomenon, and once occurring after collapse hole, difficulty is brought to construction, below put the processes such as anchor cable, slip casting.
The content of the invention
The present invention seeks to overcome the disadvantages mentioned above that prior art is present there is provided one kind is simple in construction, speed of application is fast, applies
Work efficiency high, anti-collapse hole effect good anti-collapse aperture apparatus and anti-collapse hole construction method.
To achieve the above object, the technology used in the present invention means are：A kind of anti-collapse aperture apparatus, including hollow tube, brill
Tooth and connector, hollow tube front end are fixedly connected with brill tooth, and hollow tube rear end is installed on connector, hollow tube apart from connector 150-
The through hole through hollow tube is provided with 200mm.
Further, hollow length of tube is 1100-1300mm, and hollow tube external diameter is 45mm.
Further, the through-hole diameter through hollow tube is 22mm.
A kind of anti-collapse hole construction method using anti-collapse aperture apparatus, comprises the following steps；First, rigging up support and anchor cable
Rig；2nd, a section solid drill shaft is arranged on anchor cable rig, starts the drilling of 1100 millimeters of anchor cable rig construction；3rd, take out
Anchor cable rig and solid drill shaft, anti-collapse aperture apparatus is arranged on anchor cable rig, and two are carried out on the basis of being drilled in step 2
Secondary drilling；4th, step 3 and step 4 are alternately repeated, is drilled using solid drill shaft, is then carried out again with anti-collapse aperture apparatus secondary
Drilling, until getting into design hole depth；5th, borehole cleaning and Anchor cable-rod and Grouting Pipe are installed, slip casting and exit anti-collapse aperture apparatus, marginal not
Anti-collapse aperture apparatus is exited on slurry side.
Further, a diameter of 32mm of solid drill shaft.
The beneficial effects of the invention are as follows：Anti-collapse aperture apparatus is reasonable in design, simple in construction, and service life is long, construction procedure behaviour
Make simple, constructed in the more tunnel top layer of some poor plasticities, moisture content, and obtain anti-collapse hole effect of preferably constructing
Really so that bottom plate anchor shaft anchor cable normal mounting, and solve due to the problem of anchor pole can not be installed after collapse hole, achieve good
Effect.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of anti-collapse aperture apparatus in the present invention.
In figure：1st, hollow tube, 2, bore tooth, 3, connector, 4, through hole.
