Abstract
The utility model discloses a device for clearing barrier piles, which comprises a barrier pile, a jack, a pile feeder and a reaction frame; the barrier pile is a pile foundation affecting a subway tunnel shield, the barrier pile penetrates through a subway tunnel, the top surface of the barrier pile is provided with a pile feeder, the cross section of the pile feeder is the same as that of the barrier pile, the pile feeders are in multiple sections, the pile feeders are connected through flanges, the top end of the pile feeder is provided with a jack, a reaction frame is arranged on the jack, and the reaction frame is anchored on a ground beam of a building. The utility model discloses be exactly press into the tunnel bottom to the obstacle stake and do not influence the obstacle that the shield constructs the position that removes the shield structure machine construction to the building dead weight is the counter-force, presses the obstacle stake to subway tunnel bottom with reaction frame and dedicated pile follower and does not influence the position that the shield constructs, takes out the pile follower at last and uses soil hole sealing. The utility model has the advantages of construction period is short, the expense is low, the surrounding environment influences little and the construction degree of difficulty is low.
Description
Technical field
The utility model relates to constructing metro tunnel fields, and in particular to a kind of when subway tunnel crossing Old building pile foundation
The device of removing obstacles stake.
Background technique
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, is constructed extremely difficult, therefore in Practical Project, often using 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 is pulled out again after existing building is needed to remove before pile pulling
Original building is moved back to original place again after pile pulling, the workload thus greatly increased by stake.It and 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
It connects and constructs at one layer.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 continue to use and the stake subdued can do the basis of subway.
Utility model content
Purpose of the utility model is to solve the obstacle pile problems encountered when subway tunnel shield, provide a kind of removing
The device of obstacle pile has 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 in the utility model is: a kind of device of removing obstacles stake, including obstacle pile, jack, send
Stake device 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, uses flange between Pile feeder
Connection, Pile feeder top are equipped with jack, reaction frame are equipped with above jack, and reaction frame is 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.The following steps are included:
1) first jack, Pile feeder and reaction frame are installed, reaction frame height is arranged according to Pile feeder height, with building
Object self weight is counter-force, presses jack；Selected four side of 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 circuits sequentially；
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.
The utility model has the advantages that the utility model construction method is simple, obstacle pile indentation tunnel bottom is not exactly influenced shield
A kind of method of position releases the obstacle of shield machine construction, there is that the construction period is short, expense is lower, difficulty of construction is lower, all
Collarette border, which influences small and construction period upper floor, can continue to use and the advantages that the stake subdued can do the basis of subway.
The utility model is very suitable to use in practical projects.
Detailed description of the invention
Fig. 1 is the schematic device of removing obstacles stake
Fig. 2 is that obstacle pile removes front and back schematic diagram.
Specific embodiment
Specific embodiment of the present utility model is further described with reference to the accompanying drawing:
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 equipped with reaction frame 1 above, and reaction frame 1 is 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.The following steps are included:
1) first jack, Pile feeder and reaction frame are installed, reaction frame height is arranged according to Pile feeder height, with building
Object self weight is counter-force, presses jack；Selected four side of 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 circuits sequentially；
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 the schematic diagram that obstacle pile removes front and back, 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 utility model is anchored on ground beam, then obstacle pile is pressed onto ground using reaction frame and jack
Iron tunnel bottom does not influence the position of shield, and to meet for geological conditions does not influence shield obstacle pile indentation tunnel bottom
The requirement of position and the bigger situation of obstacle pile length are simpler than with the method for pile pulling with the method for piling in this case
Very much.
The embodiments of the present invention is described in detail in conjunction with attached drawing above, but the utility model is not limited to institute
The embodiment of description.For those of ordinary skill in the art, in the range of the principles of the present invention and technical idea
