Specific embodiment
The non-fully pile foundation cushion cap under precipitation state, including pile framing iron case template and pile foundation 8 inside a kind of foundation pit,
The pile framing iron case is located on blinding concrete 10.Blinding concrete 10 uses underwater casting, slightly above designed elevation 10-
After avoiding pile framing iron case template in place, the reduction of bed course absolute altitude is made because being squeezed by 20mm.Pile framing iron case template and pile foundation
8 are blocked closely knit using pile crown water-tight concretes 12, and are set pile crown waterproof 17 on pile crown water-tight concrete 12, are effectively prevent seeping
Water.The pile framing iron case template includes pile framing iron case side wall template 1 and the pile framing iron case bottom plate 3 being attached thereto,
Iron case side wall template and iron bottom template die plate matter are steel plate.Edge sets suspension hook 2 in each pile framing iron case side wall template 1,
Suspension hook quantity in each iron case side wall template is no less than 1,2 positional symmetry of suspension hook in opposite two iron case side wall templates 1,
Sling pile framing iron case template steadily.Pile crown reserved opening side wall template 4 is set in pile framing iron case bottom plate 3.
The bottom of pile framing iron case bottom plate 3 is uniformly distributed peg 5, and 5 diameter of peg is 8-12mm, length 80-100mm, peg
Spacing 300-500mm, pile framing iron case template is tightly bonded together with blinding concrete 10.Pile crown reserved opening side
4 inside of wall form, half high-order bit sets continuous closed doughnut-shaped steel plate sealing piece 6, and 6 thickness of steel plate waterstop strip is not less than 5mm, width
Not less than 50mm.Gap position between pile crown reserved opening side wall template 4 and pile foundation 8, gap width are no less than 200mm,
The gap position uses the concrete higher than one seepage-resistant grade of pile framing concrete, is poured under water to pile crown reserved opening side
4 upper surface vibration compacting of wall form simultaneously smoothes out, and connect pile foundation 8 effectively with pile framing iron case impermeable.In pile framing iron case
It sets up defences on the inside of template water layer and protective layer 7.Pile crown anchor bar 9 is set in the pile foundation 8, in pile framing iron case bottom plate 3
On set pile framing bottom reinforcement bars 18, and set column wall joint bar 21, pile framing iron in pile framing iron case bottom plate 3 by design requirement
Pile framing side wall reinforcing bar 19 is set in case side wall template 1, pile framing bottom reinforcement bars 18 are after encountering pile crown reserved opening side wall template 4
It is folded upward at an anchorage length, pile crown reinforcement mesh reinforcing bar 20 is set on the reinforcing bar after this bending, in pile framing iron case template
The middle part level of short transverse sets distributing bar 22 in the middle part of pile framing.Casting concrete in two times in pile framing iron case template,
Pile framing iron case template installs fixed after-pouring cushion cap lower part concrete (23), then in pile framing iron case form height direction
Top is horizontally disposed with pile framing top and attached baseplate reinforcing bar 24, then carries out pile framing top and attached underplate concrete 25
It pours.
The non-fully pile foundation cushion cap production method under precipitation state inside a kind of foundation pit, includes the following steps:
1) pile framing iron case template construct: steel plate and steel welding pile extension cushion cap iron case template are used, in pile framing iron case mould
Waterproof layer is carried out on the inside of plate and protective layer 7 is constructed.
2) concrete placed under water: pouring blinding concrete 10 under water and smooth out, and the upper surface of blinding concrete 10 is high
In designed elevation 10-20mm, the settling amount of pile framing iron case is reserved.
3) pile framing iron case template is arranged: before 10 initial set of blinding concrete, lifting pile framing iron case template is in place, by setting
Meter requires position and the absolute altitude of adjustment pile framing iron case template.
4) pour bottom reserved opening: the gap position between pile foundation 8 and pile crown reserved opening side wall template 4 is adopted
Be higher than one seepage-resistant grade of pile framing concrete pile crown water-tight concrete 12, pour under water to pile crown reserved opening side
Along flushing on wall form 4, with vibrator vibration compacting and smooth out.
5) fixed section steel beam: along section steel beam 13 is placed in pile framing iron case template, by socketing reinforcing bar 14, section steel beam 13
Pile framing iron case template is connected and fixed with pile foundation 8 with pile crown anchor bar 9.
6) waterproof and reinforcing bar binding construction: in the foundation pit 11 on the outside of pile framing iron case template, backfill 15 is successively used
It carries out foundation pit backfill and the attached waterproof bottom cushion 16 of pile framing is constructed；Using pumping equipment, it is discharged in pile framing iron case template
After the water in portion, carry out pile crown waterproof 17 and construct, and on the inside of pile framing iron case template waterproof layer and the construction of protective layer 7 to waterproof
16 position of bottom cushion；Then pile framing bottom reinforcement bars 18, pile framing side wall reinforcing bar 19, pile crown reinforcement mesh reinforcing bar are successively carried out
20, the binding construction of column wall joint bar 21 and pile framing middle part distributing bar 22；Pile framing bottom reinforcement bars 18 arrive the level of pile foundation 8
An anchorage length truncation is folded upward at behind position.
7) it pours cushion cap lower part concrete: pouring cushion cap lower part concrete 23 in pile framing iron case template, wherein cushion cap
The gravity of lower part concrete 23 is greater than the buoyancy of cushion cap iron case.Then the 23 surface dabbing of concrete in cushion cap lower part is removed and is socketed
Reinforcing bar 14 and the section steel beam 13 for being placed in pile framing iron case template top bind pile framing top and attached baseplate reinforcing bar 24.
8) it pours cushion cap top concrete: pouring pile framing top and attached underplate concrete 25, be finally completed pile foundation
Bearing platform construction.
