Abstract
The invention discloses a kind of devices and operating method of removing obstacles stake, including obstacle pile, jack, Pile feeder and reaction frame；The obstacle pile is the pile foundation for influencing subway tunnel shield, obstacle pile passes through subway tunnel, obstacle pile top surface is equipped with Pile feeder, the cross sectional shape of Pile feeder is identical as obstacle stake cross sectional shape, Pile feeder is more piece, uses flanged joint, Pile feeder top to be equipped with jack between Pile feeder, jack is installed above to have reaction frame, reaction frame to be anchored on the ground beam of building.The present invention is exactly that a kind of method for the position that obstacle pile indentation tunnel bottom does not influence shield is released the obstacle of shield machine construction, using building dead weight as counter-force, obstacle pile, which is pressed onto subway tunnel bottom not, with reaction frame and dedicated Pile feeder influences the position of shield, and finally Pile feeder is taken out and uses grave hole.The present invention has the advantages that the construction period is short, expense is low, surrounding environment influence is small low with difficulty of construction etc..
Description
Technical field
The present invention relates to constructing metro tunnel fields, and in particular to when subway tunnel crossing Old building pile foundation, a kind of removing
The device and operating method of obstacle pile.
Background technology
In recent years, subway engineering was being built in numerous domestic city.Subway line route selection is often over business district and passes through
Existing building, and to the building with pile foundation, also face the cleaning problem of obstacle pile.Since these obstacle piles are mostly reinforcing bar
Concrete precast pile, when shield machine passes through, construction is extremely difficult, therefore in Practical Project, often uses after removing obstacles stake again
Carry out shield.Therefore, huge to removing obstacles stake technology development potentiality in China.To existing removing obstacles stake key technology into
Row reorganizing research is particularly important and has huge Business Studies to be worth.Removing obstacles stake used at present is mostly pile pulling
Method is the method that the stake of influence subway tunnel shield is extracted, and needs to be pulled out again after removing existing building before pile pulling
Original building is moved back to original place, the workload thus greatly increased by stake again after pile pulling.And it is influence with the method for piling
The method for the position that the stake indentation rail base of subway tunnel shield does not influence shield does not need these complicated processes, Ke Yizhi
One layer is connected on to construct.Have that the construction period is short, expense is lower, difficulty of construction is lower, surrounding environment influence is small and the construction time
Between upper floor can be continuing with and the stake subdued can do the basis of subway.
Invention content
The purpose of the present invention is to solve the obstacle pile problems encountered when subway tunnel shield, provide a kind of removing obstacles
The device and operating method of stake have the advantages that the construction period is short, expense is low, surrounding environment influence is small low with difficulty of construction etc..
The technical solution adopted by the present invention is：A kind of device of removing obstacles stake, including obstacle pile, jack, Pile feeder
And reaction frame；
The obstacle pile is the pile foundation for influencing subway tunnel shield, and obstacle pile passes through subway tunnel, the installation of obstacle pile top surface
There is Pile feeder, the cross sectional shape of Pile feeder is identical as obstacle stake cross sectional shape, and Pile feeder is more piece, and flange is used between Pile feeder
Connection, Pile feeder top are equipped with jack, and jack is installed above to have reaction frame, reaction frame to be anchored at the ground beam of building
On.
As preferred：Selected Pile feeder preferably selects 2m or so.
A kind of operating method of the device of above-mentioned removing obstacles stake.Include the following steps：
1) first jack, Pile feeder and reaction frame are installed, reaction frame height is arranged according to Pile feeder height, with building
Object dead weight is counter-force, presses jack；Four side of selected jack is symmetrically placed, and symmetrically presses jack, to prevent stress not
Uniformly obstacle pile is caused to tilt, after Pile feeder is pressed into corresponding position, accesses next Pile feeder, used between Pile feeder
Flanged joint recycles successively；
2) after obstacle pile enters subway tunnel bottom not and influences the position of shield, stop pressing jack, pile follower
Device takes out and sealing of hole.
Advantageous effect：Construction method of the present invention is simple, exactly obstacle pile indentation tunnel bottom is not influenced the position of shield
A kind of method release the obstacle of shield machine construction, have that the construction period is short, expense is lower, difficulty of construction is lower, surrounding ring
Border, which influences small and construction period upper floor, can be continuing with and the advantages that the stake subdued can do the basis of subway.This hair
It is bright to be highly suitable for using in Practical Project.
Description of the drawings
Fig. 1 is the schematic device of removing obstacles stake
Fig. 2 is that obstacle pile removes front and back schematic diagram.
Specific implementation mode
The specific implementation mode of the present invention is further described below in conjunction with the accompanying drawings：
As shown in Figure 1, a kind of device of removing obstacles stake, including obstacle pile 4, jack 2, Pile feeder 3 and reaction frame 1；
The obstacle pile 4 is the pile foundation for influencing subway tunnel shield, and obstacle pile 4 passes through subway tunnel, 4 top surface of obstacle pile peace
Equipped with Pile feeder 3, the cross sectional shape of Pile feeder 3 is identical as 4 cross sectional shape of obstacle pile, and Pile feeder 3 is more piece, between Pile feeder 3
Using flanged joint, 3 top of Pile feeder is equipped with jack 2, and jack 2 is installed above to have reaction frame 1, reaction frame 1 to be anchored at
On the ground beam of building.Selected Pile feeder 3 preferably selects 2m or so.
A kind of operating method of the device of above-mentioned removing obstacles stake.Include the following steps：
1) first jack, Pile feeder and reaction frame are installed, reaction frame height is arranged according to Pile feeder height, with building
Object dead weight is counter-force, presses jack；Four side of selected jack is symmetrically placed, and symmetrically presses jack, to prevent stress not
Uniformly obstacle pile is caused to tilt, after Pile feeder is pressed into corresponding position, accesses next Pile feeder, used between Pile feeder
Flanged joint recycles successively；
2) after obstacle pile enters subway tunnel bottom not and influences the position of shield, stop pressing jack, pile follower
Device takes out and sealing of hole.
Fig. 2 show obstacle pile and removes front and back schematic diagram, and the stake top position before obstacle pile is removed is 5, subway tunnel top
It is 7 for 6, subway tunnel bottom, the stake top position after obstacle pile removing is 8, the stake bottom position before obstacle pile removing is 9 and obstacle pile
Stake bottom position after removing is 10.
The reaction frame of the present invention is anchored on ground beam, and obstacle pile is then pressed onto subway tunnel using reaction frame and jack
Road bottom does not influence the position of shield, and the position for obstacle pile indentation tunnel bottom not being influenced shield is met for geological conditions
Requirement and the bigger situation of obstacle pile length, use the method for piling simpler than the method with pile pulling very in this case
It is more.
Embodiments of the present invention are described in detail above in association with attached drawing, but the present invention is not limited to described reality
Apply mode.For those of ordinary skill in the art, in the range of the principle of the present invention and technological thought, to these implementations
Mode carries out a variety of variations, modification, replacement and deformation and still falls in protection scope of the present invention.
