Description
Technical field
The present invention relates to colliery industry underworkings to tunnel field, more particularly to a kind of long range coal mine roadway push pipe pick
Into method.
Background technology
At present, the driving method of colliery small section tunnel mainly has two kinds：First, artificial big gun pick, two, fully-mechanized digging machine, this
Two kinds of driving methods have the limitation of itself.
One, big gun pick are the driving methods that catalase is got off using the mode of perforating explosion.Small section tunnel tunnels
Technology still with artificial big gun pick based on, big gun pick strong applicability, early period need equipment it is few, but be subject to explosive property, blasting technique,
The limitation of the conditions such as construction means, construction speed are constantly within certain limit, in particular for section is small, formation hardness
High tunnel, the pick of artificial big gun easily occur that security is low, perforating speed is slow, blasting efficiency is low, labor intensity is big, goes out cash difficulty etc. asks
Topic.
Secondly, fully-mechanized digging machine be also used for the tunneling construction of coal mine roadway, but fully-mechanized digging machine needs the weight balancing by itself
The cutting force of work surface, so machine weight is heavier, volume is larger, and the limitation such as be not easy to go into the well, and is not particularly suited for driving and is less than 10
Square metre section, when especially tunneling the harder rock gangway of rock, fully-mechanized digging machine efficiency is low, pick abrasion is severe, economic effect
Benefit is low.
The content of the invention
The purpose of the invention is to overcome the above problem, a kind of long range coal mine roadway push pipe driving side has been provided
Method.
The present invention provides a kind of long range coal mine roadway push pipe driving method, it is characterised in that：The long range coal
Ore deposit tunnel push pipe driving method, using jacking construction principle, for guarantee push pipe long distance driving and internal can be dismantled, transport,
Using following means：
Using finite element analysis and theoretical calculation method, the rock for treating construction stratum is sampled, calculates needed for construction
Push up power, design Zhu Ding mechanisms, and to relay well reasonable Arrangement, coordinate good reducing friction through injecting slurry technology, can realize single length away from
Tunneled from push pipe.
Modularized design is used to mining push-bench internal unit, each cutter of push-bench can complete tool changing in inside, pass
Dynamic system completes assembly and disassembly in inside, after push-bench driving arrives at, by push pipe rounding machine cutter, internal drive system,
Internal deslagging pump, hydraulic power unit and relay well oil cylinder and existing equipment shell depart from, and will be taken out of inside these component interior tube bodies, use
Use, device housings are stayed in existing tunnel, as support material in next engineering.
Long range coal mine roadway push pipe driving method needs advance construction working chamber, and work chamber size is 10m*8m*
6m, the construction chamber mainly arrange main jacking device, are the command modules of pipe jacking tunnelling machine.Auxiliary of the push-bench needed for remaining
Equipment, is arranged in the adit for having tunneled completion, and need to need first to dig out sedimentation basin and mud pit in adit, together
When, belt is connected at separator for mud and water, by work chamber, the winch that a load-carrying is 15 tons is set, it is each for drawing
Equipment is to destination, and work chamber figure is as shown in Figure 1.
With, it is necessary to which the random crown enters tool pipe, relay well, deslagging pump line and jacking pipe joints, having behind head jacking tunnel
Body is as shown in Figure 2.These tube couplings are all connected using socket joint, before the preceding seam allowance of later section tube coupling is inserted into after tube coupling in seam allowance,
It is sealed by sealing ring.Due to long distance driving, the multiple tool changing of mining push pipe digging device needs, and cutter quality
Heavier, the difficulty that tool changing personnel are moved to from hole inside head is larger, therefore, 2 tool pipes is closely followed in rear part of head, in work
Have arrangement reserve tools, maintenance tool, lubricating utensil and refrigeration plant inside pipe.
Long-distance pipe jacking driving is more demanding to the gross thrust of push pipe, if only increasing main jacking force, can exceed tube coupling
The limit of rupture, so hypodynamic problem is pushed up over long distances in order to make up, the suitable position increase relay well device between tube coupling,
And how to control relay well rational position be mining jacking construction key factor, traditional jacking construction mode is basis
Construction experience, relay well at one is placed every 50 meters~100 meters, but this modes of emplacement have ignored formation condition difference to top
The influence of pipe resistance, causes the waste of relay well top power.This method uses intelligent control technology, to each segment top power of push pipe
Measure and analyze, relay well is placed in rational position so that give full play to the top power of each relay well, and save
The jacking time.
Colliery push pipe driving generally uses mud and water balance mode, with the extension of jacking distance, deslagging pump and intake pump meeting
There is the problems such as energy is insufficient, this method arranges relaying deslagging pump and relaying intake pump inside tool pipe, due to tool pipe
Interior space is more nervous, using wall thickness relatively thin steel pipe arrangement relaying deslagging pump and relaying intake pump, enables in tool pipe
Leave more working spaces in inside so that operating personnel operate more convenient inside tool pipe.
Slip casting drag reduction is the important step for reducing resistance on the way, and this method uses slip casting intelligent control module, in each note
Slurry point is assembled with electric-controlled ball valve, and is mounted with that pressure passes round for a look device on tube wall, and control unit measures each pressure sensor
Data handled, draw out the outer grouting pressure cloud atlas of tube wall, and the place control electrical ball valve of slurries shortcoming is mended in time
Slurry so that the mud sleeve of overall tube coupling is complete, at utmost reduces the resistance on the way of long range jacking.
Push pipe tunneling construction mining over long distances is generally blind hole operation, and colliery can not construct in destination and receive tunnel, pass
The jacking pipe construction process of system cannot take out driving head, and this method develops a kind of head equipped with the expanding structure of shell, specially
Door is used for such a unconventional purposes, and the shell and inner shell of head equipment are bolted, handpiece case and pore-forming tunnel
Outside diameter it is identical, after the Excavation Length for reaching requirement, the bolt that handpiece case is connected with inner shell is turned on, then by head
Starting well is entirely towed back to inner shell, but shell is still remained in tunnel, and as support material, this method can be fine
Ground, which solves blind hole tunnel, can not recycle the problem of head, farthest improve work efficiency.
Advantages of the present invention：
Long range coal mine roadway push pipe driving method of the present invention, for colliery Chamber Construction, relay well arrangement, note
Slurry antifriction and head recycling etc. propose new method, solve existing coal mine roadway long-distance pipe jacking tunneling construction success rate it is low,
The problems such as speed of application is slow, head can not recycle.
