1, from the late nineteen eighties to so far documents and materials, as the data of the reaming equipment that to adopt unidirectional single-acting multiple-joint oil tank be power source, as adopting the data that corresponding two unidirectional single-acting multiple-joint oil tanks are set at the same position of this device interior, the equipment of being announced is impracticable.In the world wide of middle nineteen nineties, only China has occurred adopting bow pressing arm to implement the existing equipment of earth-squeezing hole-enlarging, but existing equipment is to produce on the basis of its advanced person's theory, because no matter be originally, still in reality, it all is very difficult removing to create practice condition in this area, so cause the mechanism of existing equipment to have the defective (but its than the technology advanced person of domestic " artificial reaming " many) of essence, and then cause domestic only a few users of family now, after having summed up the experience in several years, the soil layer of selecting to be suitable for this equipment is used this equipment (this equipment that the user who has will introduce abandons one side as scrap iron).(1) this equipment has been broken the work operation mechanism of existing equipment, one cover brand-new technology scheme has been proposed, the meaning of " two-way " that the two-way double acting multiple-joint oil tank of this equipment is pointed out, be meant the piston rod and the sleeve of this multiple-joint oil tank, can stretch accordingly with the outer shell letter of this multiple-joint oil tank, the i.e. active force that stretches out of this multiple-joint oil tank one end, act on extension shaft on the base and when having reached dispersion soil compaction executive item in soil compaction, the purpose of the bad opposite force that is produced, because the solution of bad opposite force, it can be provided with a two-way double acting multiple-joint oil tank to the inside at this equipment, has played conclusive effect (non-finger upper and lower settings).(2) regain again after axially base can stretch out, solved when soil compaction executive item soil compaction, what prevent this multiple-joint oil tank itself produces bending moment force, and prevent that this bending moment force from damaging multiple-joint oil tank, cause the soil compaction executive item to regain, and the serious problems that cause the earth-squeezing hole-enlarging special equipment to be discarded in the hole and to cause this hole to be regarded as cancelling.(3) construct in allowing the raked pile hole of using, the dispersed bad opposite force of the axial base that is lengthened out is utilized again, and it can turn to by smooth implementation in the raked pile hole automatically to this equipment, has played positive effect.(4) other end of the two-way double acting multiple-joint oil tank effect of stretching out mainly is the purpose of the high earth-squeezing hole-enlarging of implementation efficiency.The existing equipment of reaming equipment that the unidirectional single-acting multiple-joint oil tank of employing that available data is announced is a power source and the employing bow pressing arm soil compaction used by domestic a few users of family, can not realize by an oil cylinder with high thrust, big stroke promote one group of facility soil compaction and can not realize by multi-section have high thrust, the oil cylinder of stroke promotes the purpose of one group of facility soil compaction greatly.The power of this equipment multiple-joint oil tank output is consistent with the direction of soil compaction executive item extruding soil layer, and this power is utilized fully, the reaming of its energy moulding maximum.As in the limited space of this device interior, the measure of a two-way double acting multiple-joint oil tank (not being meant space up and down) is set, for this multiple-joint oil tank can have the reaming that maximum stroke, maximum thrust can the moulding maximums, played conclusive effect; This equipment is for being pushed soil layer or promoted soil compaction facility extruding soil layer jointly by its a plurality of piston rods or many bars cylinder barrel by an oil cylinder, two oil cylinder combinations, three oil cylinder combinations, three outer cylinders with the two-way double acting multiple-joint oil tank that upper cylinder is combined.When each the dish-type hole in the stake can both increase its diameter, and then can reduce the quantity in moulding dish type hole and reduce the operation number of times of soil compaction; If do not reduce the quantity in moulding dish type hole, can play shorten stake long, dwindle the stake footpath and reduce the effect of every bearing peg cost; In the less foundation soil of the bearing stratum of soil, because of the increase of disk track still can reach the purpose that improves the bearing peg bearing capacity to greatest extent.(5) implement the earth-squeezing hole-enlarging operation in the soil layer that rubble is being arranged, the soil compaction facility can prevent that also rubble from damaging oil circuit hole and oil circuit hole, loop that the outer cylinder of two-way double acting multiple-joint oil tank is provided with, and then prevent the nonrecoverable serious problems of soil compaction executive item.(6) meaning of two-way double acting multiple-joint oil tank " double acting " pointed out, be meant because the effect of oil cylinder internal hydraulic pressure oil, the two ends that this multiple-joint oil tank has been stretched out can shrink back original position again, its advantage is: do not needing to dispose under the situation of other device, regain at the two ends that the hydraulic oil of this multiple-joint oil tank inside can make this multiple-joint oil tank stretch out, the assorted renaturation of equipment that it is easy has reduced the frequency of device fails, particularly in the construction stage.(7) because the hydraulic oil of two-way double acting multiple-joint oil tank inside, the area that promotes the piston of each ante-chamber of this multiple-joint oil tank is regained the soil compaction executive item, has increased the soil compaction executive item and has clamp-oned its strength when regaining of back in the very hard stake hole hole wall soil layer for the first time.(8) because existing equipment adopts bow pressing arm extruding soil layer, in the process of its extruding soil layer, can be entered the bow pressing arm inboard by the soil of disturbance, the bow pressing arm that then should soil be retracted again is compacted, underground equipment must be carried to ground after several subjobs, by the pan soil of the removing bow pressing arm inside of artificial effort (causing this equipment to be discarded in serious consequence in the hole otherwise bow pressing arm can't be regained), and then equipment is put into a hole continue the soil compaction operation, cycle operation like this is extremely required great effort time-consuming, and this worn-out end makes existing equipment lose the practicality of operation in dry hole.This equipment soil compaction executive item does not belong to hinged bow pressing arm, so purpose that operation also can the smooth implementation earth-squeezing hole-enlarging in dry hole, it has widened the scope of reaming equipment suitable soil layer greatly, this equipment from now on improved the practicality of reaming equipment greatly, for can have been played conclusive facilitation by a large amount of popularization and applications.(9) the soil compaction executive item of this equipment is not hinged bow pressing arm, and,, above-mentioned former because this equipment played positive effect so can being provided with the native plate of shelves because the outer cylinder of the two-way double acting multiple-joint oil tank of this equipment can enter soil layer when the soil compaction operation.(10) be provided with oil circuit hole and be provided with oil circuit hole, loop or its outer cylinder and be provided with the oil circuit hole and be provided with oil circuit hole, loop in the piston rod of the two-way double acting multiple-joint oil tank of this equipment, oil circuit hole, aforementioned loop also can be on the sleeve that is located at this multiple-joint oil tank; Fuel feed pump and loop fuel feed pump respectively with oil circuit hole, the corresponding connection of oil circuit hole, loop, hydraulic oil stretches out the soil compaction executive item by the back cavity that the oil circuit hole enters in this multiple-joint oil tank, hydraulic oil regains the soil compaction executive item by the loop oilhole or/and enter each ante-chamber in this multiple-joint oil tank by the oil circuit hole, loop on the sleeve, adopt the mode of fuel feeding like this, reduced the frequency that equipment breaks down, particularly in the construction stage.(11) fuel feed pump all is connected (piston rod is connected to base with extension shaft) or fuel feed pump all is connected (outer cylinder is connected to base with extension shaft) with outer cylinder with the loop fuel feed pump with piston rod with the loop fuel feed pump, it has also played positive effect for two-way double acting multiple-joint oil tank can have maximum stroke.(12) when the operation of soil compaction executive item soil compaction, because fuel feed pump all is connected with piston rod or all is connected with outer cylinder with the loop fuel feed pump, it also can make the amount of exercise minimum of fuel feed pump and loop fuel feed pump, the amount of exercise minimum of loop fuel feed pump particularly, and prevent that above-mentioned oil pipe is connected with sleeve and oil leakage phenomenon takes place, and causes occurring the nonrecoverable serious problems of soil compaction executive item.(13) during the operation of existing equipment bow pressing arm soil compaction, also can cause a hole undergauge and cause this equipment to turn to the worn-out end of difficulty.The working mechanism of this equipment soil compaction executive item, overcome the mechanism defective that the existing equipment bow pressing arm exists, therefore when the operation of this equipment soil compaction executive item soil compaction, can not cause a hole undergauge and generation equipment turns to the worn-out end of transposition difficulty, so this soil compaction executive item can realize turning to automatically transposition smoothly to this equipment, cleared away obstacle and played extremely long-pending effect.(14) known existing reaming equipment, because on the direct or indirect outer tube wall that is hinged on this equipment of an end of its soil compaction facility, when its soil compaction facility are implemented the soil compaction operation, the bending moment force that these soil compaction facility are born is very big, and this hinged place and the outer tube that is hinged thereof are stressed also very big, and because the also outer tube of fixedly connected this equipment of its oil cylinder, the power that causes its outer tube to bear is also very big, so every soil compaction facility of two or three soil compaction facility of aforementioned device and outer tube wall thereof are quite thick and heavy; Because the height the when height of aforementioned device oil cylinder and its soil compaction facility are regained, determined that again the outer tube wall of its equipment is not only thick and heavy but also quite tall and big, particularly the equipment of three soil compaction facility of two oil cylinder promotions is heavier, so must be equipped with heavy duty crane in whole engineer operation process.Have the reaming equipment of 600 types as described above now, the crane that all need be equipped with about 16 tons could be constructed, and the operation clumsiness is mistaken, and efficient is low, the expense height.The soil compaction executive item of earth-squeezing hole-enlarging special equipment of the present invention is outer cylinder or its piston rod of two-way double acting multiple-joint oil tank, the soil compaction facility of forming by steel plate that outer cylinder connects, when it implements the soil compaction operation, track box does not stress, so, do not need thick and heavy track box, more do not need tall and big outer tube, so this device body heavy and light and short and small in sum, in the whole construction operation process, as being this equipment of 600 types equally, only needing to be equipped with the hoist engine or the outfit that have movable supporting frame and make support and hoist engine and reaming equipment movably, the light-duty vehicle that can lift by crane about 1 ton can be constructed, and is easy and simple to handle, move flexibly, the efficient height, expense is low, and it also can realize in place fast to this equipment, fuel feed pump can with equipment fast rise or decline simultaneously, and further raise the efficiency the positive effect of having played.Oil circuit hole on this equipment and oil circuit hole, loop also have the described advantage of (4) bar in the advantage 4.Above-mentioned advantage is a claim 1 of the present invention, 2,3 and the advantage of claim 5.

2, the outer cylinder of (1) two-way double acting multiple-joint oil tank of combining, for up and down superimposed, for about superimposed up and down and separable, the non-separable assembly that closes, can shared one cylinder barrel wall between the non-separable combined oil cylinder, thus reduced the area of soil compaction executive item extruding soil layer and improved its pressure soil layer.(2) two-way double acting multiple-joint oil tank sleeve inside, the diameter in the oil circuit hole on the piston that is connected, for 1mm to the interior diameter that equals the sleeve that this piston connects.Therefore when the diameter that adopts the oil circuit hole on the piston, when equaling the piston of interior diameter of sleeve, the inside of this two-way double acting multiple-joint oil tank, not by piston that sleeve at different levels connected, its inner chamber is divided into the independent oil pocket that has more than two or two, its by this piston rod and sleeve at different levels with and outer cylinder form oil pocket independently, so the two-way double acting multiple-joint oil tank of this equipment is to be promoted the cylinder bottom of this oil cylinder outer cylinder and its outer cylinder operation is stretched out by hydraulic oil, behind capable intact its stroke of this outer cylinder, its sleeve inside that drives this outer cylinder continues operation stretches out, until having gone the total kilometres that this multiple-joint oil tank had.Therefore the two-way double acting multiple-joint oil tank of this equipment is to the pressure maximum of soil layer, and when the diameter in oil circuit hole on the piston equals the interior diameter of its sleeve that connects, these pistons at different levels can be linked in together after closing and disturbing, so no matter adopting the outer cylinder of two-way double acting multiple-joint oil tank is the soil compaction executive item, still the soil compaction facility that adopt its piston rod or outer cylinder to connect are the soil compaction executive item, the total kilometres maximum of this two-way double acting multiple-joint oil tank.So the soil compaction executive item of this equipment is to pressure maximum, the stroke maximum of soil layer in sum, reaming that can the moulding maximum.(3) the oil circuit hole on the piston equals the multiple-joint oil tank of the interior diameter of sleeve, identical with joint number, oil circuit hole on its piston is compared less than the multiple-joint oil tank of sleeve diameter, the former stroke is big, latter's stroke little (this oil cylinder closes up back piston and is superimposed together), but because of when making oil cylinder, the thickness of selecting piston is arranged, the guiding of selection is arranged, oil sealing, the type of dust seal, specification, leeway such as quantity, cun timing to the greatest extent at outer cylinder, still can make and have a joint, two joints, three joints, four joints, five joints, six joints wait the multiple-joint oil tank of varying number sleeve, become to have the same stroke or the multiple-joint oil tank of same stroke not, so do not influence the purpose that it can form maximum reaming.But the two-way double acting multiple-joint oil tank of this equipment is there to be the multiple-joint oil tank of a joint sleeve, two joint sleeves, three joint sleeves, four joint sleeves.(4) no matter the oil circuit hole on the piston is greatly or little, and it all has the direction of the power of this multiple-joint oil tank output, with the consistent advantage of direction of soil compaction executive item extruding soil layer.Aforementioned advantages is a claim 1 of the present invention, 2,3 and the advantage of claim 5.

3, known existing reaming equipment owing to be subjected to the restriction of its mechanism character, can not be as required when construction or before construction, change different size, act on the native facility of different machines, its suitable soil layer scope is little, practicality is low.As adopt the reaming equipment of bow pressing arm, and original can only be promoted the operations simultaneously of two groups of bow pressing arms by an oil cylinder, change into by an oil cylinder or by two oil cylinders and promote the three groups of bow pressing arm that narrows down operations simultaneously, there are not much meanings.Earth-squeezing hole-enlarging special equipment of the present invention can be changed different size according to the variation of foundation soil complexity, acts on different soil compaction facility.As timely outside suit shape difference, the different soil compaction facility of effect at this equipment soil compaction executive item; As make a two-way double acting multiple-joint oil tank become the measures such as two-way double acting multiple-joint oil tank of multi-section combination.The transformable kind shape of this equipment soil compaction executive item have taper, frustoconical, trapezoidal, its up and down first three face be the plane or the like shape.In the soil layer with big Design of Bearing Capacity value and have and be suitable for taper soil compaction executive item in the soil layer of rubble, its boring property is strong.Side and its leading flank are the soil compaction executive item on plane up and down, its bearing capacity is the highest behind the reaming concrete perfusion of institute's moulding in soil layer, it also comprises soil compaction executive item, trapezoidal, frustoconical soil compaction executive item that the multi-section oil cylinder is combined, because the enlarged footing of the bearing peg that reaming forms of aforementioned soil compaction executive item moulding, and have collateral resistance and end load (not having collateral resistance between the enlarged footing of existing equipment institute moulding and the soil layer) between the soil layer simultaneously.So it is wide, practical that this equipment is suitable for the soil property scope, the efficient height.

4, existing reaming equipment owing to be subjected to the restriction of its mechanism, can not be provided with the breast boards that can in advance stretch out in the one or both sides of its soil compaction facility, so the said equipment can only the moulding branched hole in viscosity, plasticity hardpan and can not moulding dish type hole.Because, when existing equipment in viscosity, plasticity hardpan behind the first moulding branched hole, when following reshaping dish type hole, those hole wall soil by the disturbance of soil compaction facility can enter in the branched hole of previous moulding, and be bonded together with previous moulding hole wall, and stop up previous moulding hole, and can not moulding dish type hole; Existing equipment can produce a large amount of hacks again and increases the clear hole time in non-sticky, non-plasticity hardpan during the moulding reaming, so the existing equipment practicality is low, the suitable soil layer scope is little.(1) one or both sides of soil compaction executive item of the present invention are provided with by small-sized oil cylinder breast boards that promote, that it can be stretched out in advance, also can moulding dish type hole in viscosity, plasticity hardpan, therefore can make full use of supporting capacity, a resistance to plucking ability that all each layer pan soil fully improve.(2), in non-sticky, non-plasticity hardpan, also can stop hack and produce and save the operation of handling this hack because the existence of breast boards.(3) in the earth-squeezing hole-enlarging operation process, owing to there is not hack to produce, the whole compacted compactings of the stake hole hole wall regolith can fully improve a closely knit intensity of hole hole wall soil and improve the steadiness of foundation pile in foundation soil.(4) provide hydraulic oil for two-way double acting multiple-joint oil tank, oil circuit hole and oil circuit hole on oil circuit hole, loop or this outer cylinder and oil circuit hole, loop in this piston rod, also provide hydraulic oil for the small-sized oil cylinder that promotes breast boards, so oil circuit hole and oil circuit hole, loop on the two-way double acting multiple-joint oil tank, has double action, it has reached on the oil circuit in dynamically uses union as far as possible less, reached each the oil circuit interface in making dynamically, can all prevent oil leakage phenomenon together with moved further, it has guaranteed that breast boards stretches out smoothly and regains, prevented to regain because of breast boards, and cause the earth-squeezing hole-enlarging special equipment, be discarded in the serious consequence in the hole.In sum, this device is practical, the efficient height, and it is wide to be suitable for the soil property scope.Aforementioned advantages is a claim 1 of the present invention, 2,3 and the advantage of claim 5.

5, (1) on the top and bottom of the maximum cylinder barrel of the two-way double acting multiple-joint oil tank of this equipment or soil compaction facility or domatic spare be provided with limited block, domatic spare is connected it by screw with the soil compaction executive item, the inwall up and down of track box is provided with limited block, the inwall of domatic spare is provided with limited block, after the soil compaction executive item stretches out certain stroke, limited block on this soil compaction executive item promptly promotes domatic spare and stretches out and enter soil layer, when the reaming of above-mentioned soil compaction executive item moulding maximum and behind the box that de-orbits, domatic spare is by above-mentioned soil compaction executive item or by after the holding the shape part and drive and enter soil layer of centre, domatic spare still touches with track box.Therefore it can reach make maximum moulding hole top, following and is the inclined-plane, can prevent a hole hole wall soil collapse field boundary, can prevent to retain in the previous moulding hole hack, and it also can reach the purpose that makes in the smooth regression orbit box of above-mentioned soil compaction executive item; Limited block on the track box makes extension shaft keep in the center to base and soil compaction executive item.(2) also can be provided with in the domatic spare of this equipment top and the bottom connecting axle to the small capacity double of base to two-way cylinder, this small-sized oil cylinder can be more piece, non-multiple-joint oil tank according to required stroke, because promoting domatic spare, clamp-ons in the hole hole wall soil layer aforementioned small-sized double-action ram, so it has shared the resistance that soil layer is produced the soil compaction executive item, therefore this equipment soil compaction executive item is bigger to the pressure of soil layer, and it can the bigger reaming of moulding.
