Description
[technical field]
The utility model relates to a kind of foundation pile of building device, specifically, relates to a kind of reinforcement extruding and expanding machine.
[background technology]
Develop on the bored pile technology basis in the building pile foundation industry and a kind of new stake type.It is behind the boring machine pore-forming, potential bearing capacity for each hardpan of soil that fully undermines, load and ground situation according to stake, use a kind of hydraulic extruding extender at the pile body different parts, by installing extruding and regain and horizontally rotating the work that angle repeats again of bow pressing arm, the squeezed cavity that goes out one or several similar " flying saucer " shape.Like this, the shape at the foundation soil king-pile behind the perfusion pile singly has not been the cylinder of conventional borehole castinplace pile just, but has put on one or several " flying saucer " (calling " load dish " in the following text) on this cylindrical pillar.Decide according to geological conditions the position of load dish on pillar, and it is provided in a side of in each hardpan.Because its load disk track is 2.5 times of a warp, so this castinplace pile can have been given play to well " end holds " effect under resistance to compression, resistance to plucking condition, it and traditional castinplace pile the two basic variation has taken place on force mechanism: the former holds based on end, with friction is auxilliary, the latter is that to hold with end be auxilliary, based on friction.Generally speaking, because the end resistance is a mill tens times of resistance, under the long situation of identical geological conditions and stake footpath, stake, the former is several times of the latter for the bearing capacity of single pile, and nearly allly is suitable for adopting the latter's geological conditions all to be suitable for the former.Obviously, relatively the former is significant from economic benefit.
The title of now this stake type newly has multiple call, and the title of its construction machinery also has multiple call.As: " squeeze and expansion multi-supported plate concrete filling pile "; " DX stake (more piece reaming castinplace pile) "; " boring hydraulic pressure variable-diameter cast-in-situ pile " or the like and " extruding-enlarging branch tray machine "; " extruding branch machine "; " hydraulic pressure staving press " or the like.Principle is identical though title is various, structure is identical, technology is the same, construction machinery is identical, and just the bow pressing arm of hydraulic host machine has two and three even four s' branch; Hydraulic jack acting length, the width of unidirectional and two-way difference and bow pressing arm arranged and extrude after external dimensions have little difference.Here, we are referred to as them " squeezed castinplace pile " (being called for short " extruded and extended pile ") for the time being.These machineries are referred to as " extruding and expanding machine ".
Utilize the applying of extruded and extended pile of extruding and expanding machine construction to put into practice the history that has more than ten years, adopted extruded and extended pile in the pile foundation of thousands of object of construction production at home.Its industry relates to: smelting, heavy industry, light industry, electric power, petrochemical industry, communication, commerce, civilian, or the like.Application region almost spreads all over all parts of the country.State Power Corporation, General Acadamy of Power Planning and Design have been authorized this industry standard of " a dish bored concrete pile technology regulation " in 2000.Tianjin, Hebei province, Shandong Province, Zhejiang Province, Jiangsu Province have put into effect " the squeezed bored concrete pile technology rules " of province, city-level in succession." the extruded and extended pile standard " of some other province, city even nation-building portion is also in preparing, preparing.
But find in the construction throughout the country practice: extruding and expanding machine in the project construction of nearly half, occurs and in the hole, run into hard slightly any soil layer bow pressing arm and squeeze motionless at all and can't open.The not operation in intrinsic soil layer of way that solves, but the test that can little by little carrying out from the bottom to top in the hole in violation of rules and regulations extrude are found and can be squeezed the soil layer that moves and construct.The bearing capacity of stake is reduced greatly, bring hidden danger to workmanship; The way that former Pile Foundations Design scheme adds timber pile footpath (aperture) is changed in the employing that also has, and solves this problem, and this makes the concrete square amount of stake increase greatly again, and Project Cost improves greatly, and the economy of extruded and extended pile is had a greatly reduced quality; What also have writes an article on extruding and expanding machine, and with the bow pressing arm narrowed width that is used on the extruding and expanding machine do work, the face that will do work changes stupefied into by the plane, the resistance during with the minimizing soil compaction.But root problem does not still solve, also brought squeezed increased frequency and acting surface to become stupefied stressed dispersion of the soil layer that causes of point and the fall phenomenon of slag mechanical automatic corner return when too much and squeezed of loosened soil, hidden danger of quality such as the load disc molding is irregular, disappearance occurred by the plane owing to narrowing down of face of bow pressing arm acting.In most of project constructions, extrude smoothly soil layer exerted pressure and reach the purpose of load dish chamber moulding for reaching extruding and expanding machine bow pressing arm in the hole, relevant mechanical part is in the duty of bearing the limit always under the effect of hydraulic pressure high pressure, hydraulic pressure, mechanical breakdown often take place, and the fault of this construction link can cause shut-down completely, and the project construction duration can't be guaranteed.
At the prior art above shortcomings, the utility model is proposed.

Embodiment 1:
In the construction of extruded and extended pile, when the bow pressing arm of the extruding and expanding machine in the hole can't be opened, the indication of the hydralic pressure gauge pointer on the hydraulic power unit was that pressure value is ascending gradually, points to the limit (overflow valve is opened) at last.And the oil meter pointer when bow pressing arm can be extruded indication is: pressure value is ascending, and gradually pointer shows to be numerical value by greatly to little pressure load generation falling rapidly opening to bow pressing arm after.Proof: along with opening of bow pressing arm, angulation is increasing between the upper and lower arm, and required pressure is just more and more littler.Otherwise its angle is more little, and required pressure is just big more.Strengthen in the angle that runs into the angle between the bow pressing arm before the formal resistance of soil layer is the key (certainly, enlarging the aperture is one of method) of problem as far as possible.Be summarised as in the figure of rhombus at bow pressing arm, the angle that increases its angle can be subjected to the restriction of extruding and expanding machine (main frame) diameter (aperture just).Strengthen its angle simply under the restriction in aperture, certainly will cause the shortening of bow pressing arm, the shortening of bow pressing arm can make the reduced of load dish, and this is the forfeiture that the end of extruded and extended pile holds advantage.
With 600 existing type extruding and expanding machine is example, and the pressure of the hydraulic jack that is adopted output is about 250 tons, is powerful., be 3: 5 degree on its bow pressing arm and the angle that extruding and expanding machine host center line is become, be down 4 degree, upper and lower bow pressing arm junction angulation is 172: 5 degree, near 180 degree (differing from 7: 5 degree with the straight angle).The approximate straight-line transmitting that the power major part of oil cylinder output forms along upper and lower bow pressing arm is to the main frame bottom, absorbed by relevant parts under counteractive situation and bears and become idle work; Outwards to form the utilization of squeezed useful work very little and act on the bow pressing arm level, obviously is squeezed power deficiency, and hardpan is crowded slightly opens.
The fundamental difference of newly-designed extruding and expanding machine of the utility model and existing similar machines is except having disposed frame for extruding and expanding machine, its notable feature is exactly:
One, four bow pressing arm joints link the design that (four bearing pin types) formed a Upright Diamond mutually by four bearing pins, and this is a comparatively ideal geometric figure that makes longitudinal force become lateral force easily.It is completely different with the combination (six bearing pin types [shown in Fig. 2]) of the combination (five bearing pin types [shown in Fig. 1]) of " go up triangle with down trapezoidal " that bow pressing arm became of existing extruding and expanding machine and " upward for trapezoid be down trapezoidal ".
Two, two designs of going up " scroll wheel " of bow pressing arm positioned beneath of " shuttle type arm " effect, an acting action that makes extruding and expanding machine are finished (both twice actings of mechanism point and hydraulic action point) by two application points respectively, and it has realized breakthrough to the stiff squeezed theory of mechanics of hydraulic pressure that relies on a geometric figure stress deformation from start to finish and do work.
