Abstract
The utility model discloses a digging and cutting machine cutter used for construction adopting a TRD (trench cutting and re-mixing deep) wall method. The digging and cutting machine cutter comprises a machine frame, a horizontal guide rail and a longitudinal guide rail, a cutting box driving device is arranged on the longitudinal guide rail, a cutting box is connected on the lower side of the cutting box driving device and internally comprises a chain and a chain fixing device, and cutter bodies are fixed on the chain and are arranged on the outer side, the left side and the right side of the chain. The digging and cutting machine cutter used for construction adopting the TRD wall method solves the problem that enormous resistance of gravel and soil on two sides of the chain to the cutting box easily causes chain damage; in addition, the gravel and soil on the two sides of the chain are cut and are sufficiently mixed with solidifying liquid injected afterwards, and accordingly construction quality is improved.
Description
Technical field
The utility model relates to building machinery field, is a kind of digging machine cutter for the construction of TRD engineering method specifically.
Background technology
TRD engineering method (Trench-Cutting & Re-mixing Deep Wall Method), is developed by Japan the beginning of the nineties, is can be in all kinds of soil layers and a complete set of equipment and the construction method that become continuously wall in sand gravel layer.Its general principle is to utilize in the vertical insert into stratum of chain saw type toolbox, then do horizontal cross motion, do upper and lower gyration by chain-driving cutter simultaneously, stir mixed platform original soil and pour into cement paste, form certain thickness body of wall, to replace conventional high pressure jet grouting at present, the colonnade formula diaphragm wall of single shaft and multi-shaft cement agitation pile composition.In construction method, the diaphragm wall junction that traditional SMW engineering method is brought, in conjunction with bad, produces the defect of seepage; SMW engineering method is implemented the general degree of depth of Extra-Deep Foundation Pit and is no more than 20m, and the effect extreme difference of deep-layer stirring while exceeding cannot ensure the overlap joint effect between stake and stake.In addition, when the construction of SMW engineering method, need to extract a large amount of underground water out, cause the profligacy of water resource; In addition, also cause surface settlement, building is around caused damage; When SMW engineering method, noise is larger, larger on the life impact of surrounding resident.In addition, the position relationship of cutter and chain greatly affects construction speed and construction quality, as cutter is only arranged on the outside of chain, and the sandstone earth that when digging, cutter can only cutting chain outside, and the sandstone earth of chain both sides produces great resistance to cutting box, easily cause chain to damage; In addition, the sandstone earth of chain both sides is not cut, therefore, not of uniform size, not through mixing fully, brings thus construction quality bad with the consolidation liquid injecting subsequently.
Utility model content
For solving the problems of the technologies described above, it is minimum that the purpose of this utility model is to provide a kind of pump-out, can not cause surface settlement and noise less, can to chain both sides sandstone earth fully cut and with the well-mixed digging machine cutter of consolidation liquid, particular content is as follows:
For a digging machine cutter for TRD engineering method construction, comprise machine frame, cross slide way, longitudinal rail; Cutting box drive unit is set on described longitudinal rail, and described cutting box drive unit downside connects cutting box, comprises chain and chain fixer in described cutting box, and described chain is fixed with cutter; It is characterized in that: described cutter is arranged on outside and the left and right sides of described chain.
For adapting to different foundation soil situations, described cutter comprises the cutter that is arranged on chain outside and the cutter that is arranged on chain both sides, described in be arranged on chain outside cutter with the cutter that is arranged on chain both sides not in same level.
The described cutter that is arranged on chain outside, and becomes one in same level with the cutter that is arranged on chain both sides.
The utility model has the advantages that: the sandstone earth that the utility model has overcome chain both sides produces great resistance to cutting box, easily cause chain to damage this problem; In addition, the sandstone earth of chain both sides is cut, through mixing fully, brings thus construction quality to improve with the consolidation liquid injecting subsequently.

Detailed description of the invention
Illustrate the utility model below in conjunction with accompanying drawing, as shown in Figure 4, cutter is made box-shaped (girff) by 3.5m full-length to concrete technology route of the present utility model, so that an installation spreading successively plays guiding and supporting role to chain simultaneously.Chain is equipped with blade, drives soil body motion together with blade plate, takes ground out of always, and carries it into again undergroundly at the opposite side of girff, forms composite soil comparatively uniformly.Total length after girff combination determines the degree of depth of TRD, and depth capacity can reach 50m.The thickness of TRD is determined by the thickness specification of girff, is 450mm to 850mm.On ground after digging, inject consolidation liquid by slurry filling machine, in the vertical direction with original position soil mix and blend, at the firming body of underground formation wall shape.
Digging machine as shown in Figure 1-Figure 3, comprise machine frame 1, described machine frame arranges mobile device and hydraulic leg 1 time, described mobile device comprises crawler belt 2, caterpillar drive 3, cross slide way 4 is set on described machine frame, on described cross slide way 4, longitudinal rail 8 is set, described longitudinal rail 8 is driven and can on cross slide way 4, be moved around by horizontally moving device; On described longitudinal rail 8, cutting box drive unit 6 is set, described cutting box drive unit 6 drives and can on longitudinal rail 8, move by being arranged on longitudinal hydraulic means 9 on machine frame; Interior motor and the speed-changing gear box 5 of arranging of described cutting box drive unit 6, described cutting box drive unit 6 downsides connect cutting box 7, comprise chain 11 and chain fixer 71 and actuating arm 72 in described cutting box 7, and the outside of described chain 11 is fixed with cutter 10; Described motor and speed-changing gear box 6 drive the actuating arm 72 of cutting box to rotate, shown in the rotation of actuating arm 72 be converted to chain by gear break-in, speed change and rotate around chain fixer 71, and then band cutter 10 rotates around chain fixer 71.
For adapting to the different digging degree of depth, described cutting box 7 is many groups, can longitudinally connect its chain drive 71, and chain 11 is fixed on to chain drive 71 outsides after connection, forms the larger cutting box 7 of longitudinal length.
Cutter digging ground, injects consolidation liquid in the ground after digging subsequently, in the vertical direction with original position soil mix and blend, at the firming body of underground formation wall shape.
As shown in Figure 5, for adapting to different foundation soil situations, described cutter 10 comprises the cutter 101 that is arranged on chain outside and the cutter 102 that is arranged on chain both sides, described in be arranged on chain outside 101 cutter with the cutter 102 that is arranged on chain both sides not in same level.
As shown in Figure 6, when ground is harder, when more, be the intensity that strengthens cutter containing stone amount, described in be arranged on chain outside cutter 101 with the cutter 102 that is arranged on chain both sides in same level, and become one.
Caterpillar drive 4 of the present utility model, cutting box drive unit 6, longitudinal hydraulic means 9, chain fixer 71 all can adopt general technology, do not repeat them here.
