Detailed description of the invention

The utility model principle is, utilize hydraulic drive work system, using liquid as working media, pressure is sent to each jack under water by manoeuvring platform on the bank, wherein main jack and the end, cut jack 5 and arrange 2 groups, and effect is respectively: promote alloy cutter head cutting by amputation pile body 9, secondary jack and pushing tow jack 7 arrange 1 group, be arranged on machine top, by the top amputating pile body 9, make it produce moment of flexure for promoting, thus pile foundation is ruptured from cut point.

The utility model comprises: jack 5, upper push bracket 6 and pushing tow jack 7, upper frame 14 are cut in lowest limit position knife rest 1, cutter head 2, middle stand 3, tail stand 4, the end.

Below in conjunction with drawings and Examples, the utility model is described in further detail.

Embodiment 1: as shown in Figure 1, lowest limit position knife rest 1 is the empty long framework of middle part dew, inside it, by afterbody, be anteriorly installed the end and cut jack 5, and cut jack 5 front end connection cutter head 2 at this end, stand 3 in the installation of upside in the middle part of lowest limit position knife rest 1, in the middle part of lowest limit position knife rest 1, tail stand 4 is installed in upside simultaneously, in middle stand 3 upper end and tail stand 4 upper end level, upper frame 14 is installed, upper frame 14 is installed pushing tow jack 7, upper push bracket 6 in gate, on front side of middle stand 3 lower end hinged on bottom push bracket 6, connect pushing tow jack 7 front end on rear side of upper push bracket 6 upper end.

In aforementioned, in the middle part of lowest limit position knife rest 1 or inwall is installed righting guide beam, this righting guide beam and the end, to cut in the middle part of jack 5 or to be anteriorly connected.

In aforementioned, in knife rest 1 front end frame of lowest limit position, edge is outstanding and relative with blade on front side of cutter head 2.

In aforementioned, install hanger 8 on the upside of upper frame 14, hanger 8 is for being extension lifting hawser 10.

In aforementioned, diagonal brace 11 in tilting to be connected between upper frame 14 with lowest limit position knife rest 1.

In aforementioned, in knife rest 1 front end frame of lowest limit position, front jaw crossbeam 12 is installed in edge and upside.Front jaw crossbeam 12 is that knife rest 1 front portion, lowest limit position strengthens structure, is also the braced structures coordinating shear action with cutter head 2.

In aforementioned, top board 13 is installed on front side of upper push bracket 6 or inner side.Top board 13 keeps being continuously applied support forward or impetus to by amputation pile body 9 rear portion.

In the utility model embodiment, what lowest limit position knife rest 1, middle stand 3 and tail stand 4 etc. were formed cuts stake machine frame, selects the special high strength steel plate of bridge (YB168-70) assembly welding to form, equipment overall length 2.5m, high 1.5m, wide 1m.The model that jack 5 and pushing tow jack 7 hydraulic jack select German BAIER hydraulic power company to produce is cut at the end: the single-acting General hydraulic jack composition of RC-1006, wherein two are set in parallel in bottom for advancing cutter head, one is arranged on top for oblique promotion pile body, hydraulic jack supporting capacity of taking blame for others is 100ton, stroke 260mm, hydraulic cylinder effective area 133.2cm3, body height 449mm, stretch height 709mm, external diameter 178mm.Cutter head is made up of high-strength stainless steel alloy steel, for cutting by amputation pile body 9 and reinforcing bar.

The utility model embodiment is in work progress, as shown in Figure 2, according to by amputation pile body 9 construction stake footpath, with reference to construction parameter table pack respective amount module, the conduit under fluid pressure being cut jack 5 and pushing tow jack 7 rear portion the end by hydraulic quick coupler directly will cut stake machine and be connected to working platform; Cylinder is by lifting hawser 10 again, is hang lifting body, will cuts stake machine and suspend in midair under water, and amputated outside pile body 9 by the anterior ring set of lowest limit position knife rest 1 from hanger 8, and one group of lifting hawser 10 is tied up by amputation pile body 9 upper end simultaneously; Adjustment cuts stake machine height to suitable section of stake position, and jack 5 is cut at the startup end, clamps the stake face needing to block; The system pressure that the intensity of the mixed earth poured into a mould according to stake regulates, to oil cylinder pressurization, suppresses lower fracture until to be cut in cutter head 2 and front jaw crossbeam 12 folder by amputation pile body 9 concrete pile; When being about to block by amputation pile body 9 pile body, start pushing tow jack 7, promote, by the top amputating pile body 9, to make it produce moment of flexure, thus pile foundation is ruptured from cut point, then directly utilize lowest limit position knife rest 1 lifting force to be promoted by the concrete block of amputation and move to assigned address.

In the utility model, simple to operate, high efficiency, low noise, low cost, is applicable in pile group construction works.Cut stake machine and adopt high modularization combination, by pin shaft joint module, can disparate modules number combinations be passed through, amputation certain limit interior diameter pile crown.

The utility model, without the need to water operation under diver, all manipulates on the bank, reduces manual labor and security risk.Be adapted to any water quality waters, especially in water turbidity, pollution, the more aobvious advantage in waters that corrosivity is serious.Clipping time short (3-5 divides/root), greatly increase work efficiency, the reduction of erection time.Easy and simple to handle, equipment, spillage of material are little.Cost-saving, reduce construction costs.Applied range, can be used under water, the land amputation such as all kinds of concrete components, steel beam column, Wood member, reinforcing bar.
