Description
Technical field
The present invention relates to weathered mudstone layer cutting technique field, especially a kind of TRD engineering method cutting chain saw for deep basal pit gravel layer and rock stratum construction.
Background technology
Exploitation in 1993 that TRD engineering method is Japanese kobe steel a kind of utilizes construct the continuously construction technology of equal thickness cement-earth underground continuous wall of saw chain formula cutting box, this construction method is that some blade rows are arranged on saw chain by certain assembled arrangement, become the cutting of wall by the blade row on cutting box drive saw chain, blade row is the cutting element that is provided with some cutter hubs.
TRD engineering method adopts the structure of monolithic cutter head frame both sides configuration cutting cutter head, the alloy cutter head of this structure is arranged on the both sides of trapezoidal knife rest upper end, the cutter hub alloy cutter head cutting power of this structure a little less than, only can cut the shale layer of uniaxial compressive strength≤5MPa, and tool bit abrasion is serious, cutting speed is slow, cutting box link broken screw, chain derailing and chain locating rack very easily occur to drop, cause engineering to be forced to suspension of works, greatly increase bury drills risk and construction cost, had a strong impact on construction quality and construction speed.
Summary of the invention
The object of the invention is a kind of TRD engineering method cutting chain saw for gravel layer and rock stratum construction not enough for prior art and design, adopt single cutting blade row and the spaced blade row group of two cutting blade row structure, the weathered rock formation of machinable uniaxial compressive strength≤10MPa, effectively improve cutting ability and the speed of cutter head, prevent that cutting box link broken screw, chain derailing and chain locating rack from dropping, reduce bury drills risk and construction cost, further improve construction quality and construction speed.
The concrete technical scheme that realizes the object of the invention is: a kind of TRD engineering method cutting chain saw for gravel layer and rock stratum construction, comprise the pairing golden head blade row being arranged on chain saw, be characterized in that chain saw is provided with pairing golden head blade row and single alloy head blade row, single alloy head blade row is set in parallel on chain saw and with chain saw as being fixedly connected with at certain intervals with pairing golden head blade row; Described pairing golden head blade row forms by welding several pairing golden head cutter hubs on knife plate; Described pairing golden head cutter hub is made up of the both sides welding rectangle alloy cutter head of double-end knife top of the trellis; Described single alloy head blade row forms by welding several single alloy head cutter hubs on knife plate; Described single alloy head cutter hub is made up of welding vertex of a cone alloy cutter head in the middle of single head knife rest top.
Described double end knife rest is the trapezoidal plate of " protruding " word.
Described single head knife rest is the trapezoidal plate of " recessed " word.
Described several rectangle alloy cutter head bodies and single alloy head cutter hub for vertical, tilt or height is straggly is fixedly connected with knife plate.
The present invention compared with prior art has simple in structure, the weathered rock formation of machinable uniaxial compressive strength≤10MPa, greatly improve the anti-wear performance of cutting speed and cutter head, prevent that preferably cutting box link broken screw, chain derailing and chain locating rack from dropping, reduce bury drills risk and construction cost, reliability is high, further improves construction quality and construction speed.
