Abstract
The invention discloses a concrete cutting advanced cutter for a shield tunneling machine, and belongs to the field of shield tunneling machines for tunnel construction. The cutter is structurally characterized in that alloy 2 and alloy 3 are welded on a cutter body 1, wherein the alloy 2 is positioned at two ends of the cutter body; the alloy 3 is positioned between the two pieces of the alloy 2; blade parts of the alloy 2 and the alloy 3 are wedge-shaped; and tungsten carbide granular wear-resistant material is laid and welded on the cutter body 1. The wedge-shaped blade parts of the cutter are used for cutting a pile foundation and breaking down concrete when the shield tunneling machine meets the pile foundation and a glass fiber reinforced concrete diaphragm wall in front during the construction, so that a common advanced cutter and a scraper on a cutter head panel are prevented from being damaged by the pile foundation. The invention has the advantages that the cutter has a simple structure and high reliability, is low in cost and convenient to use, can effectively overcome the disadvantage that the shield tunneling machine is required to pull out the pile foundation to pass through when meeting the pile foundation during the construction, reduces the construction time, saves the construction cost and improves the construction efficiency, and is widely applied to the industry of shield tunneling machines.
Description
Technical field
The present invention relates to constructing tunnel shield machine parts, relate in particular to shield machine and when construction, run into pile foundation, but fast shut-off pile foundation broken pile guarantees that shield machine tunnels smoothly.
Background technology
Shield machine is a kind of special engineering machinery of tunnel piercing.The front portion of existing shield machine mainly contains: the cutterhead of forefront, the anterior shield otch ring at cutterhead rear portion and again after Tu Cang etc.The multiple cutters such as replaceable pilot cutter of scraper, hobboing cutter, dual-pilot cutter and replacement hobboing cutter are installed on the cutterhead, and the perforate on the cutterhead forms slag inlet.During work, cutterhead rotation under the rotarily driving of cutterhead, is installed in the excavation that the various cutters on the cutterhead finish the soil body and cuts.The soil body that cuts enters the Tu Cang at anterior shield otch ring and rear portion thereof by the slag inlet on the cutterhead, carry backward again.
In work progress, because the stratum is complicated and changeable, when shield machine runs into pile foundation and glass reinforced concrete ground-connecting-wall in tunneling process, use shield machine with cutting the concrete dual-pilot cutter, can cut off better pile foundation and abolish concrete, effectively solve and run into pile foundation in the shield-tunneling construction and must pull out pile foundation and could pass through drawback, reduce the time of construction, save construction cost, improve the advantage of efficiency of construction.
Summary of the invention
The purpose of this invention is to provide a kind of shield machine with cutting concrete dual-pilot cutter cutter.Effectively solve and run into pile foundation in the shield-tunneling construction and must pull out pile foundation and could pass through drawback, reduce the time of construction, saving construction cost, raising efficiency of construction; And it is simple in structure, and is with low cost, and reliability is high, easy to use.
The present invention realizes its goal of the invention, and the technical scheme that adopts is: a kind of shield machine is with cutting concrete dual-pilot cutter cutter, and its design feature is: welding alloy 2 and alloy 3 on cutter hub 1, and alloy 2 is positioned at the cutter hub two ends; Alloy 3 is between two blocks of alloys 2, and alloy 2 is wedge shape with alloy 3 blades, and spreads weldering tungsten carbide particle high-abrasive material on cutter 1.
Compared with prior art beneficial effect of the present invention is: this cutter is not subjected to the impact in cutter path and space, can be installed on the cutter head panel in any track on.Shield machine runs into pile foundation and glass reinforced concrete ground-connecting-wall or other bad grounds in tunneling process; use shield machine with cutting the concrete dual-pilot cutter; can cut off better pile foundation and abolish concrete; protect better other common dual-pilot cutter and scrapers, effectively solve and run into pile foundation in the shield-tunneling construction and must pull out pile foundation and could pass through drawback, reduce the time of construction; save construction cost; improve efficiency of construction, have practical, fitting operation is convenient and simple in structure, the advantage that cost is low.
Description of drawings
Figure of description is schematic diagram of the present invention.Fig. 1 is front view and left view, and Fig. 2 is top view, and 1 among the figure is cutter hub, the 2nd, and carbide alloy 2,3rd, carbide alloy 3.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated.
As shown in Figure 1, 2.A kind of shield machine is with cutting concrete dual-pilot cutter cutter, and whole cutter is by cutter hub 1, carbide alloy 2, carbide alloy 3; At cutter hub 1 upper berth weldering carbine abrasion-proof material, cutter hub 1 and carbide alloy 2, carbide alloy 3 are welded by money base Welding mode.
The operating principle of cutter is: when shield machine the place ahead runs into pile foundation and glass reinforced concrete ground-connecting-wall in work progress; can utilize the wedge shape blade of this cutter to cut off first pile foundation and concrete; abolish pile foundation and the soil body in advance; thereby common dual-pilot cutter and scraper on the protection cutter head panel are not destroyed by pile foundation; significantly increase the flowability of the cutting soil body; greatly improve stock-removing efficiency; reduce the loss of cutter; effectively solve and run into pile foundation in the shield-tunneling construction and must pull out pile foundation and could pass through drawback; reduce the time of construction; save construction cost, improve efficiency of construction.
Claims (3)
1. a shield machine is with cutting the concrete dual-pilot cutter, and whole cutter arrangement is comprised of cutter hub 1, alloy 2, alloy 3, connects mode with carbide alloy 2 and carbide alloy 3 by the money base soldering behind the cutter hub 1 shop weldering carbine abrasion-proof material and is welded and fixed, and assembly welding becomes solid tool.
2. shield machine according to claim 1 is with cutting the concrete dual-pilot cutter; it is characterized in that: the operating principle of said cutter is; when shield machine runs into pile foundation in working environment; utilize the wedge shape blade of this cutter to cut off pile foundation; and cut the soil body in advance; with soil body cutting whole into sections, thereby common dual-pilot cutter and scraper on the protection cutter head panel are not destroyed by pile foundation.
3. shield machine shield machine according to claim 1 is with cutting the concrete dual-pilot cutter; it is characterized in that: the method for work of said cutter is; can be welded on any track of cutter head panel; cut the soil body in advance; abolish pile foundation in advance; can protect at any time common dual-pilot cutter and scraper, significantly increase the flowability of the cutting soil body, greatly improve stock-removing efficiency.
