Abstract
The utility model discloses an unequal space extruding expander for enhancing the bearing capacity of filling piles. A piston rod in an oil cylinder can be controlled by a hydraulic power unit which is arranged outside a machine body through an M-shaped manual change valve, a transmission guide rod can be driven to push an extruding and expanding board which is connected by a shaft pin, and accordingly, the extruding and expanding actions to a hole wall can be completed. The utility model which has reasonable design adopts four branch mechanisms, can be suitable for extruding and expanding hole walls in various soft and hard soil layers of different kinds, can improve the bearing capacity of a single pile by more than one time as compared with straight hole piles, can save investment by from 45% to 60%, and can improve construction period by from 20% to 30%.
Description
The utility model does not wait the component space extruding and expanding machine, is the construction machinery that improves pouring pile bearing capacity.
Two branch's Pile extruders in the existing foundation construction technology can only planar push branch, when pore-forming being carried out the extruding of four branches, need carry out twice extruding; Finish for the first time push branch after, extruding branch machine needs half-twist to push again, as pore-forming being carried out branch when extruding dish, extruding branch machine need carry out four extruding actions, when one 20 meters dark pore-formings are pushed, need tens times extruding to move with two branch's extruders, because the action of extruding repeatedly, muddy water in the stirring pore-forming will seriously influence not waiting of extrusion modling and prop up four stupefied bodies, and the repeatedly extruding of long period will make the possible undergauge of four stupefied bodies or the slump of extrusion modling, thereby not only exist and take a lot of work, time-consuming, expensive, shortcomings such as power consumption, also can bring difficulty for design and construction because of being difficult to guarantee that the effect of branch's branch dish influences the quality of pile body.
The purpose of this utility model is to overcome above-mentioned shortcoming, provides that a kind of speed is fast, efficient is high, can carry out four branch's pile hole extruding-extending machines of space extruding branch.
For achieving the above object, scheme of the present utility model is: cut down the in-oil cylinder piston rod of control by being located at extra-organismal hydraulic power unit by M type manual reverse of direction, drive transmission guide rod, promotion is finished the squeezed action to hole wall with the upper and lower squeezed plate that pivot pin is connected.
The bottom of above-mentioned transmission guide rod is provided with and fixedly connects dish, and the other end that connects dish connects four groups of squeezed plates, and every group of squeezed plate formed by upper and lower squeezed plate, and the bottom of following squeezed plate is connected with the member of organism bottom, and formation can form four linkage in space.
Because such scheme adopts four branched structures, squeezed number of times is few when pore-forming is carried out branch's branch dish, is suitable for the squeezed hole wall of various soft or hard soil layers of different nature, and single pile bearing force rate straight hole pile is enhanced about more than once, save investment 45-60%, improve the duration more than 20-30%.And squeezed moulding, the dish quality all can be effectively guaranteed.
Be described further below in conjunction with accompanying drawing
Figure one is an extruding and expanding machine operating principle schematic diagram
Figure two is extruding and expanding machine sectional views
Figure three is partial sectional views of extruding and expanding machine view
Figure four, five, six is the reaming shaping schematic view
Extruding and expanding machine is by pumping plant 14 in the schematic diagram shown in the figure one, and oil pipe 13 is formed through tube connector 12 and casing 9.
Figure two is extruding and expanding machine sectional views, in casing 9, be shaped on oil cylinder 8, be provided with piston rod 7 in the oil cylinder, the lower end of piston rod is connected with transmission guide rod 5, the outside of transmission guide rod is shaped on guideway 6, sealing ring 10 is equipped with at the two ends up and down of axle sleeve, to prevent that silt from entering oil cylinder, the bottom of transmission guide rod is provided with and fixedly connects dish 4, the other end that fixedly connects dish is connected with four groups of squeezed plates with pivot pin, the lower end of going up squeezed plate 3 connects squeezed plate 2 down with pivot pin, and the bottom of following squeezed plate is connected on the connecting elements 1 of organism bottom.(length that goes up squeezed plate is greater than following squeezed plate)
Forming machine of the present utility model is the hydraulic connecting rod extruding and expanding machine, during work with conventional basic pore-forming equipment, get the main aperture of respective aperture, with crane this machine is hung in main aperture again, be placed into the relevant position by the Pile Foundations Design size, pumping plant links to each other with the oil cylinder upper and lower cavity through oil pipe, the motion of stockaded village alive bar in the control oil cylinder, by the linkage that transmission guide rod is formed that squeezed plate release is external again, the soil outside the squeezed hole, form and do not wait the four stupefied bodies that prop up, finish reaming and give system work.Only need body rotation one time 45 during as squeezed branch dish.The angle can be finished.
