A kind of modified earth tunnel excavates auxiliary equipment, for the instrument of tunnel excavation in category construction project.It includes cutter hub, and cutter hub rear end is knife wall, and knife wall is fixed on excavator machine bucket.Its key technology is to set knife ploughshare in cutter hub front end, and knife ploughshare front end is triangle hack cushion block, is knife support between knife ploughshare and knife wall, and knife support upside is recessed semicircle.The invention has the advantages that：Knife ploughshare emphasis is used for broken excavation, in the front of cutter hub, triangle hack cushion block is set, the contact area of cutter hub and excavation face is increased, compared to a kind of " weak broken wall rock tunnel excavator excavates servicing unit " the slow defect of a rate of advance, apparatus of the present invention speed of application is fast and economical；The defect easily caved in when being excavated compared to common big machinery, when apparatus of the present invention are excavated to shallow tunnel swelled ground weak surrounding rock, the disturbance to weak surrounding rock is small, prevent landslide, construction safety, difficult problem is excavated for latent swelled ground stratum of burying, and can be met latent swelled ground stratum of burying and be constructed.
Description
Technical field：
A kind of modified earth tunnel excavates auxiliary equipment, for the instrument of tunnel excavation in category construction project.
Background technology：
" cover Sinorael road " is largest domestic scale coal-transporting line --- cover west and transport railway to Central China coal, " illiteracy Sinorael road " North gets
The Inner Mongol is great to strangle the lucky station of report, and terminal reaches Jiangxi Province Ji'an, 1837 kilometers of total track length, and planning and designing conveying capacity is 200,000,000 tons/
Year.Cover Sinorael road laterite ridge tunnel domestic positioned at Nanyang City, Henan Province Neixiang County Tuan Dong towns, teacher hilllock.Tunnel uses one-tunnel two-tracks shape
Formula, inside sets open roof, and tunnel maximum buried depth 204m, the minimum depth 3.93m, most of exposed bedrock, Local topography has broken product
Clay distribution.Laterite ridge tunnel outlet section is swelled ground stratum, and tunnel cutting is difficult to form Load -carring arch, and soil property is poor, the minimum depth
Only 3.93m, easily collapses and collapses, and security risk is high.Tunnel top is the clay of special expansion structure, is received with water-swellable, dehydration
The characteristics of contracting, Surrounding Rock Strength is low, self-stable ability is poor, and country rock is poor, there is native stone line of demarcation, while there is certain bias in tunnel,
Stability control is difficult during excavation, it is impossible to take drill-blast tunnelling, when directly being excavated using large scale equipment, contact surface is excessive, to soft
Weak country rock disturbance is excessive, easily causes Shallow-Buried Soft Rock landslide, and security is not enough.The patent No. 2016200385530 discloses " one
Plant weak broken wall rock tunnel excavator and excavate servicing unit ", it includes being located at the bucket tooth fixed seat of power shovel both sides, bucket
Bucket tooth is fixed in tooth fixed seat.This device can efficiently control tunnel excavation contour line, it is to avoid Tunnel Overbreak ＆ Underbreak, but the dress
Put front contact site single, a rate of advance slowly, influences construction speed；Due also to its structure is straight sheet, its torque is straight
Line torque, when stress is excavated, due to opposing torque effect, abrasion is also easy to produce for excavation equipment connecting portion, expends maintenance
Time, influence construction speed.For earth tunnel, how to improve, the existing excavation equipment of integrated application, realize that super shallow-buried tunnel is fast
Speed, safety, economic construction, requirement higher is proposed to excavation equipment.
The content of the invention：
The problem to be solved in the present invention is not enough aiming at more than and it is small to provide a kind of disturbance to weak surrounding rock, construction peace
Entirely, stabilization is excavated, the fast earth tunnel of speed of application excavates auxiliary equipment.Its technical scheme is as follows：
A kind of modified earth tunnel excavates auxiliary equipment, including cutter hub, and cutter hub rear end is knife wall, and knife wall is fixed on excavation
On machine machine bucket.Its key technology is to set knife ploughshare in cutter hub front end, and knife ploughshare front end is triangle hack cushion block, knife ploughshare and knife wall it
Between be knife support, knife support upside is recessed semicircle.
Compared with prior art, the invention has the advantages that：
1st, knife ploughshare emphasis of the present invention is used for broken excavation, and triangle hack cushion block is set in the front of cutter hub, increases knife
Body and the contact area of excavation face, delay compared to a kind of " weak broken wall rock tunnel excavator excavates servicing unit " a rate of advance
Slow defect, apparatus of the present invention speed of application is fast and economical；The defect easily caved in when being excavated compared to common big machinery, this
When invention device is excavated to shallow tunnel swelled ground weak surrounding rock, the disturbance to weak surrounding rock is small, prevents landslide, construction peace
Entirely, difficult problem is excavated for latent swelled ground stratum of burying, latent swelled ground stratum of burying can be met and constructed.
2nd, the recessed semicircle design of knife support part so that torque concentrates on knife ploughshare, increases hack pressure, it is ensured that excavate stabilization,
Realize rapid construction.
3rd, the recessed semicircle design of knife support part, can produce conveying to act on, for suddenly encountering hard rock mass to excavating dregs
Or weak soil, it is not to fly to jump out to come, it is ensured that construction safety.
4th, knife support part of the present invention is arranged to recessed semicircle, relative to " a kind of weak broken wall rock tunnel excavator excavates auxiliary
Help device " straight line torque, apparatus of the present invention change torque direction, existing skill are considerably less than to the abrasion of excavation equipment connecting portion
Art, it is ensured that equipment is used for a long time, will not be because frequently repairing influence construction speed.
5th, 2~3cm of cutter hub thickness, increases its bearing capacity, excavates stabilization, service life extension.
Brief description of the drawings：
Fig. 1, is schematic structural view of the invention；
Fig. 2, is stereogram of the present invention.
Specific embodiment：
Referring to Fig. 1 and Fig. 2, the present invention includes cutter hub 5, and the rear end of cutter hub 5 is knife wall 6, and knife wall 6 is fixed on excavator machine bucket
On.Its key technology is to set knife ploughshare 2 in the front end of cutter hub 5, and the front end of knife ploughshare 2 is triangle hack cushion block 3, knife ploughshare 2 and knife wall 6 it
Between be knife support 4, the upside of knife support 4 is recessed semicircle 1.
The length of the recessed semicircle 1 is 10~15cm, and depth is 5~10cm.
The thickness of the cutter hub 5 is 2~3cm.
Operation principle of the invention is：
When the poor position of the engineering geological conditions such as rich clay, expansive soils is excavated, cutter hub is arranged on excavator
On machine bucket, with the construction of excavating equipment, knife ploughshare 2 is crushed for front, then crushes block in top squeeze, release effect
Under, the recessed semicircle 1 along knife support slides, and excavates steady, quick, safety, and other equipment has operating efficiency higher on year-on-year basis.
