Abstract
The utility model relates to a shield constructs construction field, specifically is a rich water sandy gravel stratum slurry shield tunnelling is protected footpath and is made up sword. It is frequent to have solved the tool changing of current rich water sandy gravel stratum slurry shield tunnelling, have a big risk, the degree of difficulty is big, the problem low with the work efficiency with high costs, a rich water sandy gravel stratum slurry shield tunnelling is protected footpath and is made up sword, including the shell blade disc, be equipped with the owner on the shell blade disc, vice width of cloth strip, highly different front blade disc shell sword of symmetrical bilayer is gone up to main width of cloth strip, dispose peripheral hobbing cutter on the inclined plane of the main width of cloth strip of shell blade disc, peripheral hobbing cutter outside welding has the serrated knife, the serrated knife both sides are equipped with wear -resisting protection piece. The utility model discloses the not only wear -resisting reduction tool changing of the peripheral major diameter serrated knife of make full use of reduces the construction risk, utilizes the first disturbed strata of serrated knife wearing and tearing moreover, reduces stratum tool setting mill and decreases and improve hobbing cutter tunnelling work efficiency. The flexible operation is convenient, has advantages such as simple process, advanced technology, practicality are strong.
Description
Technical field
This utility model relates to shield-tunneling construction field, is specially a kind of rich water sand-pebble layer slurry shield driving gauge group
Close cutter.
Background technology
China is in subway construction high-tide period, and 90% interval employing shield-tunneling construction, some cities exist rich water sandy gravel ground
Layer, tool changing is frequent, difficulty is big, risk is big, cost is big, work efficiency is low to use slurry shield driving, rich water sand-pebble layer muddy water shield
The a great problem of Shield Construction Method Used is perplexed in structure tool changing always, how to configure the cutter focus that always whole world is discussed, waits all
Reason occurs in that in tunneling process cutterhead is stuck, tool wear is serious, tool changing is difficult, construction speed is slow, earth's surface easily caves in
Problems, various tooling setup belong to the exploratory stage, how to have configured cutter and have adapted to rich water sand-pebble layer speedy drivage, have subtracted
Few number of changing knife, thinks to improve shield-tunneling construction progress to greatest extent, reduce shield-tunneling construction security risk also need to study further with
Explore.There is presently no a kind of preferably rich water sand-pebble layer periphery gauge combination cutter.
Summary of the invention
The driving tool changing of existing rich water sand-pebble layer slurry shield is frequent, risk big, difficulty in order to solve for this utility model
Greatly, the problem that cost is high and work efficiency is low, it is provided that a kind of rich water sand-pebble layer slurry shield driving gauge combination cutter.
This utility model takes techniques below scheme: a kind of rich water sand-pebble layer slurry shield driving gauge combines cutter,
Including shell cutterhead, shell cutterhead is provided with major and minor spoke, and main spoke is symmetrically welded bilayer the most different front cutterhead
Shell cutter, the inclined-plane of the main spoke of shell cutterhead is configured with periphery hobboing cutter, is welded with serrated knife, serrated knife both sides outside periphery hobboing cutter
It is provided with wear-resistant protection block.
The aperture opening ratio of described major and minor spoke is 48%.
The digging diameter 4CM bigger than shell cutterhead of described periphery hobboing cutter, the digging diameter of described serrated knife rolls than periphery
The big 1CM of cutter.
Compared with prior art, this utility model has the advantage that
1) i.e. to extend the driving time longer for cutting knife both sides welding wear-resistant protection block, and effect protection periphery hobboing cutter, reduces tool changing again
Frequency, reduces construction cost；
2) cutting knife is than the periphery big 1CM of hobboing cutter digging diameter, and after serrated knife weares and teares, periphery hobboing cutter starts to play a role, abrasion
Rear serrated knife not only reduces the stratum abrasion to cutterhead, and plays first disturbed strata, reduces hob abrasion and improves excavation efficiency.
In a word, this utility model not only makes full use of the wear-resisting minimizing tool changing of periphery major diameter serrated knife, reduces construction risk, and
And utilize the first disturbed strata of serrated knife abrasion, reduce stratum and to cutterhead abrasion and improve hobboing cutter excavation efficiency.Flexible and convenient operation, tool
Have that technique is simple, advanced technology, the advantage such as practical.
Accompanying drawing explanation
Fig. 1 is cross-sectional schematic diagram of the present utility model；
Fig. 2 is this utility model A-A generalized section；
In figure: 1-shell cutterhead；2-front cutterhead shell cutter；3-periphery hobboing cutter；4-serrated knife；5-wear-resistant protection block.
Detailed description of the invention
As shown in Figure 1, 2, a kind of rich water sand-pebble layer slurry shield driving gauge combination cutter, including shell cutterhead 1, shellfish
Shell cutterhead 1 is provided with major and minor spoke, and main spoke is symmetrically welded bilayer the most different front cutterhead shell cutter 2, shell cutter
Being configured with periphery hobboing cutter 3 on the inclined-plane of the main spoke of dish 1, be welded with serrated knife 4 outside periphery hobboing cutter 3, serrated knife 4 both sides are provided with wear-resisting
Protection block 5.
The aperture opening ratio of described major and minor spoke is 48%.
The digging diameter of described periphery hobboing cutter 3 4CM bigger than shell cutterhead 1, the digging diameter of described serrated knife 4 compares periphery
The big 1CM of hobboing cutter 3.
Case history
Combination gauge combination cutter is for No. 9 line 7 Biao Wang river way stations of Shenyang Metro to Cao Zhong station speciality rich water sand-pebble layer
Interval, interval long 2240 meters.First against rich water sand-pebble layer, cutterhead being optimized design, cutterhead uses shell cutter cutterhead
Design, and on cutterhead king spoke inclined-plane, configure gauge combination cutter.Realize left and right line shield driving without a break to carry out often to ventilating shaft
Pressure tool changing, reduces tool changing with pressure during driving.Proving this advanced technology, methodological science is reasonable.
This utility model has been generalized in other speciality rich water sandy gravel slurry shield tunnels driving, has been greatly improved shield
Structure excavation efficiency, reduces number of changing knife, it is ensured that rich water sand-pebble layer is efficiently constructed and safety, achieves good economic benefit
And social benefit, in practice it has proved that, this technical scheme is practical, and promotion prospect is good.
