Abstract
A method for welding a side wing type steel pipe pile to reinforce a foundation comprises the following steps: pile sinking is carried out according to a common steel pipe pile sinking method; when the pile body length of the common steel pipe pile reaches two thirds of the designed pile length, pressing the pile by using the side-wing type steel pipe pile until the pressure displayed by the hydraulic jack reaches the designed pressure; the side-wing type steel pipe pile is characterized in that a plurality of steel plate side wings are welded on the outer wall of the pile body; welding the last section of pipe pile after the pressure reaches the design pressure, driving a steel plate wedge, electrically welding to jack the foundation tightly, and finally pouring concrete into the steel pipe. The invention solves the problem of overlong pile body length caused by complex stratum structure in the existing building foundation reinforcement, and has the characteristics of simple device manufacture, high pile sinking efficiency, reduced construction cost and easy quality guarantee.
Description
Technical field：
The invention belongs to brick or concrete duct field, it is related to a kind of welding side wing type steel pipe pile reinforcedly
The method of base.
Background technology：
Reinforcement means for existing construction foundation and basis sinking is a lot, the most common are steel
Pipe concrete static pressed pile, i.e., by the use of structural weight per square meter as counter-force, with jack by pile cutoff from base
Plinth base pressure enters supporting course, reaches design pressure and depth, then stake is linked together with basis,
Stake is formed, superstructure load is shared by pile body and foundation soil collective effect, made up original
Natural foundation bearing capacity is not enough, controls settlement of foundation.Pile body steel pipe segmentation press-in ground is (every
One meter is one section), steel pipe is welded with electroslag pressure welding, until pressure reaches design pressure.
Usual this type steel pipe sunk pile is carried out using such as Fig. 1 methods.
The conventional method of the above mainly has a disadvantage that：1st, due to formation complex structure,
The underground soil supporting course bearing capacity of same depth different location differs greatly, and causes to be partially completed
Pile body length is long, causes the waste of material.2nd, pile body length in part is long, causes to apply
The extension of work duration.3rd, pile body length is long in work progress, and poor quality ensures.
The content of the invention：
It is an object of the invention to provide a kind of method for welding the steel pipe pile reinforced ground of side wing type,
Solve the pile body length caused due to earth formation complexity in existing construction foundation reinforcing
Long problem, and with device make simple, pile sinking efficiency high, construction cost reduction,
The characteristics of quality is easily guaranteed that.
As above conceive, the technical scheme is that：One kind welding side wing type is steel pipe pile reinforced
The method of ground, it is characterised in that：Comprise the following steps：
1. pile sinking is carried out by common steel tube sunk pile method；
2. when ordinary steel tubular pile body length reaches designing pile length 2/3rds, side wing type is used instead
Steel-pipe pile carries out piling, untill hydraulic jack display pressure reaches design pressure；It is described
Multiple steel plate flanks are welded with side wing type steel-pipe pile pile body outer wall；
3. final stage pile tube is welded after pressure reaches design pressure, and after squeezing into steel plate wedge
It is welded to hold out against basis, finally the penetration concrete in steel pipe.
Above-mentioned steel plate flank is welded on side wing type steel-pipe pile pile body outer wall in quincuncial arrangement.
Above-mentioned final stage pile tube is ordinary steel pile tube.
The present invention is welded with the steel-pipe pile of multiple steel plate flanks to increase top stake by press-in
The side friction of body, solves part pile body and is spent because pile body that earth formation complexity causes is long
Problem long.And with device make simple, pile sinking efficiency high, construction cost reduction,
The characteristics of quality is easily guaranteed that.

Specific embodiment：
A kind of method for welding the steel pipe pile reinforced ground of side wing type, comprises the following steps：
1. carry out pile sinking by common steel tube sunk pile method, conventional steel pipe stake include steel cushion block 3,
Hydraulic jack 4, ordinary steel tubular pile body 5 and steel pipe pile crown 6；(as shown in Figure 1)
2. when ordinary steel tubular pile body length reaches designing pile length 2/3rds, flank is used instead
Formula steel-pipe pile 9 carries out piling, is until the display pressure of hydraulic jack 4 reaches design pressure
Only；Multiple steel plate flanks 8, these steel plates are welded on the side wing type steel-pipe pile pile body outer wall
Flank is welded on side wing type steel-pipe pile pile body outer wall in quincuncial arrangement.(such as Fig. 2,3,4,
Shown in 5)
3. final stage pile tube is welded after pressure reaches design pressure, and (final stage pile tube is general
Logical steel pipe stub member 5a), and be welded to hold out against basis, finally in steel pipe after squeezing into steel plate wedge 10
Interior penetration concrete.(as shown in Figure 6)
Claims (3)
1. it is a kind of weld the steel pipe pile reinforced ground of side wing type method, it is characterised in that：Bag
