Abstract
The invention discloses a rock penetrating reaming device, which comprises a hollow central shaft, a front guide, a rear guide, a reamer and a pull-out device, wherein two ends of the central shaft are communicated with a drill stem; the reamer is arranged between the front guide and the rear guide; the pull-out device is arranged on the lower part of the central shaft and comprises a tubular main body; the middle part of the main body is provided with a fluidic element; and the fluidic element is communicated with the central shaft and ejects mud or clear water from the drill stem towards the back side of the interior of the main body at a high speed, and pumps mud and rock debris at the front of the reamer to the back port of the main body from the front port of the main body under the action of negative pressure. The rock penetrating reaming device can guarantee that a hole bottom at a cutting position of the front part of the reamer is clean; the working efficiency is increased as repeated crushing is not required; and the abrasion of the reamer is reduced and the service life of the reamer is prolonged.
Description
Technical field
The present invention relates to rock crossing construction field, particularly relate to a kind of rock and pass through Counterboring apparatus.
Background technology
At present, non-excavation passes through engineering and has been widely used in the petroleum gas hydraulic pipe, and such as transfering natural gas from the west to the east, project of South-to-North water diversion, and the various pipe works such as sewage conduct, power pipe are laid, but, in hard rock, pass through to creep into and remain a global difficult problem.This mainly is because in the lithostratigraphy, and when especially crept on sandstone and conglomerate stratum, the deslagging difficulty repeated broken seriously, causes that drilling efficiency is low, the drilling tool wearing and tearing are very serious.Also do not solve at present the apparatus and method of this difficult problem both at home and abroad.
Summary of the invention
The purpose of this invention is to provide and a kind ofly be easy to that deslagging, drilling efficiency are higher, the less rock of drilling tool wearing and tearing passes through Counterboring apparatus.
The objective of the invention is to be achieved through the following technical solutions:
A kind of rock passes through Counterboring apparatus, the central axis that comprises the hollow that two ends are communicated with drilling rod, leading to, rear guiding, be arranged on described leading to and rear guiding between reamer, comprise that also one is arranged on the device that detaches of described central axis bottom, describedly detach the main body that device comprises a tubulose, at the middle part of described main body one fluidic is installed, described fluidic is communicated with described central axis and will sprays at a high speed to described body interior rear side from mud or the clear water of drilling rod, under the effect of negative pressure the mud of described reamer front and landwaste is evacuated to rear port from the front port of described main body.
Described fluidic comprises housing and is arranged on nozzle ring in the described housing, and described housing is communicated with described central axis by a tube connector, and described nozzle ring is communicated with described main body and towards the inside of described main body rear side.
Described reamer is gear wheel or replaceable roll-type rock reamer.
Rock of the present invention passes through Counterboring apparatus and forms negative pressure by the fluidic that is installed on gear wheel or the replaceable roll-type rock reamer in detaching device, under suction function, newly restrain the rear portion that the landwaste of getting is evacuated to reamer with detaching the mud of device front and landwaste and the drill bit of hole inner accumulated, guaranteed at the bottom of the anterior cutting of the reamer hole, position clean, need not the repetition fragmentation, thereby can fast drilling, reduced the wearing and tearing of reamer, improved the application life of reamer.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further specified.Wherein:
Fig. 1 is the structural representation that rock of the present invention passes through Counterboring apparatus;
Fig. 2 utilizes device of the present invention to carry out the schematic diagram of crossing construction;
Fig. 3 is the partial enlarged drawing of Fig. 2.
The specific embodiment
Below in conjunction with Fig. 1 the structure that rock of the present invention passes through Counterboring apparatus is elaborated.
As shown in the figure, this rock passes through Counterboring apparatus and comprises: the central axis 21 of the hollow that two ends are communicated with drilling rod, leading to 22, rear guiding 24, be arranged on described leading to 22 and rear guiding 24 between reamer 23 and the device that detaches that is arranged on central axis 21 bottoms.Described reamer is gear wheel or replaceable roll-type rock reamer.
Describedly detach the main body that device comprises a tubulose, the front end of main body is slag suction mouth 25, and the rear end is slag-drip opening 29.At the middle part of described main body one fluidic is installed.This fluidic comprises housing 26 and is arranged on nozzle ring 27 in the housing 26, and described housing is communicated with central axis 21 by tube connector 28.Nozzle ring 27 is communicated with described main body and towards the inside of main body rear side.
Below in conjunction with Fig. 2 and Fig. 3 the using method that rock of the present invention passes through hole enlarging drilling device is described.
11 is rig among the figure, and 12 is the mountain that need pass through, and 13 is the river that need pass through, the 14th, and slush pump, 15 is the lithostratigraphy, and 1 for treating reaming, and 4 for expanding metapore, and 2 is anterior drilling rod, and 7 is the rear portion drilling rod, and 21 is the central axis of reamer, and 23 is reamer.Mud or clear water are pumped into reamer 23 by slush pump by anterior drilling rod 2 or rear portion drilling rod 7, and through at a high speed outflow of fluidic 26, thereby generation negative pressure, form suction force, bullport 1 rock slag 5 interior and that reamer 3 cuts is extracted into the rear portion of reamer 23, clean at the bottom of assurance rock reamer 23 front aperture, do not repeat fragmentation, so that reamer 23 cuts fresh rock all the time, reach the purpose of efficient reaming, eliminated simultaneously the wearing and tearing of 5 pairs of rock reamers 23 of anterior rock slag.Outside the rock slag that is pumped to reamer 23 rear portions portals with the mud low-speed flow, perhaps outside the hole flushing operation tap of back.
