The purpose of embodiment.
Fig. 1 and Fig. 2 are please referred to, Fig. 1 is Two bors d's oeuveres channel steel structural schematic diagram.Fig. 2 combines signal with to pile pulling for Two bors d's oeuveres channel steel
Figure.The utility model proposes a kind of Two bors d's oeuveres channel steels to assist pile pulling device, comprising: a whole set of vibration hammer equipment and hydraulically operated fixture, and
For assisting the Two bors d's oeuveres channel steel 01 of pile pulling；01 inside and outside wall of Two bors d's oeuveres channel steel is fixedly installed protrusion 11, the Two bors d's oeuveres channel steel
The edge of a wing of single channel steel is arranged at intervals with bolt hole 12, and the Two bors d's oeuveres channel steel 01 is attached by bolt.
Two bors d's oeuveres channel steel provided by the utility model assists pile pulling device, a whole set of vibration including comparative maturity in the prior art
Hammer equipment and hydraulically operated fixture and one are for assisting the Two bors d's oeuveres channel steel (Two bors d's oeuveres channel steel 01) of pile pulling.The channel steel inside and outside wall is solid
Surely it is provided with protrusion (protrusion 11).Multiple groups ellipse hole is additionally provided on the channel steel wall.The Two bors d's oeuveres channel steel it is single
A bolt hole (bolt hole 12) is arranged every 1m in the channel steel edge of a wing, and Two bors d's oeuveres channel steel is connected by plain bolt.Which kind of rule specifically selected
The channel steel of lattice, need to according to the stake of institute's pile pulling 31 long, stake diameter and geological conditions come flexible choice.A whole set of vibration hammer equipment and hydraulic
It is not introduced in fixture this specification.Hydraulically operated fixture is mainly used to clamp at the top of channel steel, allows to move freely up and down.
The Two bors d's oeuveres channel steel bottom is provided with 2 rotatable active pins (active pin 41) simultaneously.Active pin one end shaft
51 are welded on channel steel web inner wall, and the other end is up-side down triangle section free end.The active pin is in channel steel vibration-sunk process
It is middle to be in close state because channel steel inner wall is close in the extruding of Pile side soil body always.After channel steel, which is sunk down into, requires depth, pass through
Hydraulically operated fixture promotes channel steel and starts pile pulling, and in channel steel uphill process, active pin free end up-side down triangle section is rubbed because of Pile side soil body
It wipes power and slides down to horizontal position along fixing end shaft, active pin is in the open state at this time.It, will after channel steel is promoted to earth's surface
Pile body takes out at the top of channel steel, manually closes active pin.
The fixed lobe rounds along channel steel inside and outside wall, and section is half elliptic, long axis 10cm, and semi-minor axis is
2cm, protrusion is every one of 2m setting.
Multiple groups ellipse hole 21 is additionally provided on the channel steel wall, each group of pore quantity is 8, and single channel steel is set
4 are set, wherein each 1 of the edge of a wing, web 2.Each ellipse hole long axis is 10cm, short axle 4cm.Multiple groups ellipse hole
In same group of hole height of holes it is identical, and be located at that twice protrusion is intermediate to be evenly arranged, i.e., be arranged along channel steel short transverse every 2m
One group.
The channel steel height is 20~50cm bigger than stake diameter to be pulled out, and channel steel embedded depth is 2 times bigger than pile body length
Stake diameter.
Fig. 3 is the sinking of channel steel 02.
Fig. 4 is pile pulling body 31 on channel steel 02, and active pin 41 is in the open state at this time, and pile body weight transfer is to active pin 41, so
Channel steel 02 is passed to by active pin 41 afterwards.
Fig. 5, Fig. 7, Fig. 8 are the channel steel 02 that active pin 41 is in close state.
Fig. 6, Fig. 9, Figure 10 are the channel steel 02 in the open state of active pin 41.
Figure 11 is the process that channel steel sinking pile body is pulled out.
Process 1: excavating stake top earthing, exposes stake top.Long, stake diameter, geological conditions, flexible choice channel steel specification according to stake.
Channel steel is clamped using vibration hammer and hydraulically operated fixture, channel steel center is made to be directed at pile center, starts vibration hammer, is shaken by stake top
Channel steel sinks.
Process 2: channel steel side shake edge pile body direction sink, active pin is during channel steel vibration-sunk because of stake side at this time
The extruding of the soil body is close to always channel steel inner wall and is in close state, if it find that channel steel has, skewness is serious, then adjusts at any time
Whole tup direction.
Process 3: when channel steel embedded depth 2 times of stake diameter bigger than pile body length, stop sinking, pile body is complete by channel steel at this time
It encases entirely.It keeps in situ constant, sufficiently vibration certain time, so that fixed lobe is cut pile peripheral earth by shaking channel steel, so that
The side friction of the inside and outside wall of channel steel and stake end and the cohesive force of supporting course soil greatly reduce.
Process 4: promoting channel steel by hydraulically operated fixture and start pile pulling, and in channel steel along the uphill process of pile body direction, active pin is certainly
By end up-side down triangle section because Pile side soil body frictional force along fixing end shaft slides down to horizontal position, active pin is in and beats at this time
Open state.Pile body and the soil body being attached on pile body self weight are born jointly by active pin and channel steel.
Process 5: when above pulling out channel steel, channel steel and pile body are above pulled out together to earth's surface.
Process 6: pile body is taken out at the top of channel steel, manually closes active pin, stake holes is backfilled and tamps, pile pulling terminates.
In conclusion the utility model has developed one kind on the basis of existing pile pulling technology and method, for its defect
Two bors d's oeuveres channel steel assists pile pulling device, and core technology is the active pin that channel steel bottom can be rotated along shaft.The Two bors d's oeuveres channel steel assists pile pulling
Equipment can sink in channel steel, pile pulling during environmental protection, efficiently pull out various pile-type, and cost is relatively low, does not stay security risk.
The active pin is in close state during channel steel vibration-sunk, and in channel steel uphill process, active pin is free
End slides down to horizontal position and in the open state automatically, and active pin, which is closed, opens without being controlled by other supplementary modes,
Whole process efficient quick.The fixed lobe being arranged on the channel steel inside and outside wall can in channel steel sinking watching extruded channel
The interior outside soil body, the soil body and channel steel inside and outside wall distance itself of extruding increase, so that the frictional force of channel steel inside and outside wall and the soil body is big
It is big to reduce, to reduce pile pulling power, substantially increase pile pulling efficiency.The multiple groups ellipse hole being arranged on the channel steel wall
It can sink in channel steel and prevent vacuum suction effect in uphill process, to reduce pile pulling power, improve pile pulling efficiency.
Although the utility model has been disclosed with preferred embodiment as above, so it is not intended to limit the utility model.This reality
It is without departing from the spirit and scope of the utility model, each when that can make with novel those of ordinary skill in the art
Kind changes and retouches.Therefore, the protection scope of the utility model is subject to view those as defined in claim.
