Description
[technical field]
The present invention relates to a kind of construction methods of foundation pit, and in particular to a kind of waterproof company of foundation pit uplift pile and structure base slab
The construction method of binding structure belongs to base pit engineering technical field.
[background technique]
Currently, engineering construction occurs, there are many case where bottom plate infiltration, and there are many influence factor, wherein the water-proofing treatment of pile crown
And particularly important one.The side that traditional pile crown waterproof construction is combined using waterproof roll, water-repellent paint, sealing material
Formula carries out water-proofing treatment, not only time-consuming and laborious, but also cannot be guaranteed waterproof effect.
Pile head waterproofing will solve three difficult points: 1. because pile crown is not to pour simultaneously with bottom plate, on pile crown periphery, stake top
With the concrete construction joint of concrete floor connecting part.2. blinding concrete shrinks the gap generated between pile crown.3. pile crown
Surrounding bed course is because there are the gaps that differential settlement generates for the reasons such as the compactness difference of following soil.
Therefore, in order to solve the above technical problems, foundation pit uplift pile and structure base slab it is necessory to provide a kind of innovation
The construction method of waterproof connecting structure, to overcome the defect in the prior art.
[summary of the invention]
The purpose of the present invention is to provide the construction method of a kind of foundation pit uplift pile and the waterproof connecting structure of structure base slab,
It does not need to carry out pile crown above-mentioned traditional pile crown waterproof construction in practice of construction, has convenience for construction and economical rationality
Property.
To achieve the above object, the technical scheme adopted by the invention is as follows: a kind of waterproof of foundation pit uplift pile and structure base slab
The construction method of connection structure, including following construction procedure:
(1) soil body is constructed at pile crown: the soil body at pile crown is tiltedly dug out an inverted round stage along the stake whole body with 45 ° of inclination angle
Body；
(2) cushion construction: when carrying out construction of the structure base slab with underlayer, equally construction is around pile crown with a thickness of d's
Bed course, bed course is constructed around pile body with 45 degree of inclination angles at pile crown；
(3) pile crown amputates: pile crown being amputated to D/4 below the absolute altitude of structure base slab lower surface, and waterproof construction and cleaning
Base cleans up base's sundries, dust, lime-ash, base's acceptance(check)；
(4) Slab Waterproof Construction: the construction of waterproof slab is carried out before concreting, waterproof material is with a thickness of h；
(5) assembling reinforcement: binding structure baseplate reinforcing bar, by resistance to plucking pile head Reinforcement and structure base slab master
Muscle is connected in a welding manner；
(6) concreting: rest around structure base slab and pile crown is poured jointly to be formed one it is unified mixed
Solidifying soil is whole, and the concrete height poured below the absolute altitude of structure base slab lower surface is exactly D.
The construction method of the waterproof connecting structure of foundation pit uplift pile and structure base slab of the invention is further are as follows: step 1)
In, uplift pile diameter is set as D, and cushion thickness d, with a thickness of h, dig deep depth is waterproof material?
It is exactly oblique dig to below the absolute altitude of structure base slab lower surfacePlace, when construction, are taken as integer, and the face tiltedly dug out is i.e.
For the side of rounding stage body.
The construction method of the waterproof connecting structure of foundation pit uplift pile and structure base slab of the invention is also are as follows: in step 3), stake
Waterproof at head is constructed around pile body with 45 ° of inclination angles.
Compared with prior art, the invention has the following beneficial effects: foundation pit uplift pile of the invention and structure base slabs
The construction method of waterproof connecting structure is amputated pile crown to lower surface of base plate hereinafter, concrete pours by amputating part pile crown more
It is poured at pile crown using rounding stage body when building, same casting concrete at pile crown, such construction joint has been left in distance structure bottom
Plate lower surfaceThe lower part pile body at place avoids and construction joint is stayed in stake top is connected with concrete floor
Position, effectively prevent structure base slab reinforcing bar and be corroded.
Meanwhile pile concrete is poured and is poured using rounding stage body, for 45 ° of bed courses, i.e., inclination angle is constructed in rounding stage body lower part
Mat layer concrete is shunk, and the intrusion of water can be effectively prevented in the concrete more poured, but also can be effectively reduced uneven
Settle the gap generated.
[Detailed description of the invention]
Fig. 1 is the structural schematic diagram of uplift pile of the invention.
In figure: 1. structural floorings；2. waterproof material；3. bed course；4. pile body steel bar stress；5 pile bodies；6. baseplate reinforcing bar.
[specific embodiment]
It please refers to shown in Figure of description 1, the present invention is the waterproof connecting structure of a kind of foundation pit uplift pile and structure base slab
Construction method, including following construction procedure:
(1) soil body is constructed at pile crown: setting uplift pile diameter as D, cushion thickness d, waterproof material is with a thickness of h, by stake
The soil body at head tiltedly digs out a rounding stage body along the stake whole body with 45 ° of inclination angle, and digging depth isAlso
It is oblique dig to below the absolute altitude of structure base slab lower surfacePlace, when construction, are taken as integer, and the face tiltedly dug out is
The side of rounding stage body.Reverse frustoconic, which pours, to protect baseplate reinforcing bar not to be etched, and prevent from leading since pile head waterproofing is improper
The bottom plate of cause seeps water.
(2) cushion construction: when carrying out construction of the structure base slab with underlayer, equally construction is around pile crown with a thickness of d's
Bed course, bed course is constructed around pile body with 45 degree of inclination angles at pile crown.
(3) pile crown amputates: pile crown being amputated to D/4 below the absolute altitude of structure base slab lower surface, and waterproof construction and cleaning
Base cleans up base's sundries, dust, lime-ash, base's acceptance(check)；Wherein, waterproof construction does not need to carry out at pile crown
The complicated operational procedures such as sealing rod, waterstop and sealant construction, only need to be using the same waterproof with other parts under bottom plate
Material and operational procedure, unlike, the construction of waterproofing work is carried out along pile body with 45 ° of inclination angles at pile crown.
(4) Slab Waterproof Construction: the construction of waterproof slab is carried out before concreting, waterproof material is with a thickness of h；
(5) assembling reinforcement: binding structure baseplate reinforcing bar, by resistance to plucking pile head Reinforcement and structure base slab master
Muscle is connected in a welding manner；
(6) concreting: rest around structure base slab and pile crown is poured jointly to be formed one it is unified mixed
Solidifying soil is whole, and the concrete height poured below the absolute altitude of structure base slab lower surface is exactly D.
The present invention is certain below uplift pile lower surface of base plate absolute altitude by pile crown by the way that pile crown has been amputated a part more
Distance, while having poured the concrete at pile crown more, pile crown surrounding concrete is poured jointly with structure base slab, is guaranteeing resistance to plucking
Under the early period of the uplift effect of stake resistance to plucking, the concrete more poured, which is wrapped in pile crown, can improve uplift pile and structure base slab junction
Waterproof performance.
Above specific embodiment is only the preferred embodiment of this creation, all in this wound not to limit this creation
Any modification, equivalent substitution, improvement and etc. done within the spirit and principle of work, should be included in this creation protection scope it
It is interior.
