Description
【Technical field】
The present invention relates to a kind of construction method of foundation ditch, and in particular to a kind of foundation ditch uplift pile connects with the waterproof of structure base slab
The construction method of binding structure, belongs to base pit engineering technical field.
【Background technology】
At present, engineering construction occur base plate infiltration situation it is a lot, its influence factor is a lot, wherein the water-proofing treatment of pile crown
It is also particularly important one.The side that traditional pile crown waterproof construction is combined using waterproof roll, water-repellent paint, encapsulant
Formula carries out water-proofing treatment, not only wastes time and energy, and it cannot be guaranteed that waterproof effect.
Pile head waterproofing will solve three difficult points：1. it is not while pour, in pile crown periphery, stake top with base plate because of pile crown
With the concrete construction joint of concrete floor connecting part.2. blinding concrete shrinks the gap produced and between pile crown.3. pile crown
There is the gap of differential settlement generation because of the not equal reason of the packing of following soil in surrounding bed course.
Therefore, in order to solve the above technical problems, it is necessory to provide a kind of foundation ditch uplift pile of innovation with structure base slab
The construction method of waterproof connecting structure, to overcome the defect of the prior art.
【The content of the invention】
It is an object of the invention to provide a kind of foundation ditch uplift pile and the construction method of the waterproof connecting structure of structure base slab,
It need not carry out above-mentioned traditional pile crown waterproof construction in practice of construction to pile crown, with convenience for construction and economical rationality
Property.
To achieve the above object, the technical scheme taken of the present invention is：A kind of foundation ditch uplift pile and the waterproof of structure base slab
The construction method of attachment structure, including following construction procedure：
(1) soil body construction at pile crown：The soil body at pile crown is tiltedly dug out into an inverted round stage along the stake whole body with 45 ° of inclination angle
Body；
(2) cushion construction：When carrying out structure base slab with the construction of underlayer, same construction thickness is d's around pile crown
Bed course, bed course is constructed around pile body with 45 degree of inclination angles at pile crown；
(3) pile crown amputation：Pile crown is amputated to structure base slab lower surface absolute altitude at D/4, and waterproof construction and cleaning
Basic unit, basic unit's debris, dust, lime-ash are cleaned up, basic unit's acceptance(check)；
(4) Slab Waterproof Construction：The construction of waterproof slab is carried out before concreting, waterproof material thickness is h；
(5) assembling reinforcement：Binding structure baseplate reinforcing bar, by the Reinforcement at resistance to plucking pile head and structure base slab master
Muscle is connected in a welding manner；
(6) concreting：To locate around structure base slab and pile crown rest pour jointly to be formed one it is unified mixed
Solidifying soil is overall, and the concrete poured below structure base slab lower surface absolute altitude is highly exactly D.
Foundation ditch uplift pile of the invention is further with the construction method of the waterproof connecting structure of structure base slab：Step 1)
In, a diameter of D of uplift pile is set, cushion thickness is d, and waterproof material thickness is h, digs deep degree and is
It is exactly tiltedly to dig to below structure base slab lower surface absolute altitudePlace, is taken as integer during construction, the face tiltedly dug out is i.e.
It is the side of rounding stage body.
Foundation ditch uplift pile of the invention is also with the construction method of the waterproof connecting structure of structure base slab：Step 3) in, stake
Waterproof at head is constructed around pile body with 45 ° of inclination angles.
Compared with prior art, the present invention has the advantages that：Foundation ditch uplift pile of the invention and structure base slab
The construction method of waterproof connecting structure is amputated to base plate lower surface pile crown by many amputation part pile crowns, and concrete is poured
Poured using rounding stage body at pile crown when building, same casting concrete at pile crown, such construction joint has been left in distance structure bottom
Plate lower surfaceThe bottom pile body at place, it is to avoid construction joint is stayed in into stake top is connected with concrete floor
Position, effectively prevent structure base slab reinforcing bar and be corroded.
Meanwhile, pile concrete is poured and poured using rounding stage body, and rounding stage body bottom construction inclination angle is 45 ° of bed courses, i.e.,
Mat layer concrete shrinks, and the concrete for pouring more can effectively prevent the intrusion of water, but also can effectively reduce uneven
Settle the gap for producing.
【Brief description of the drawings】
Fig. 1 is the structural representation of uplift pile of the invention.
In figure：1. structural flooring；2. waterproof material；3. bed course；4. pile body steel bar stress；5 pile bodies；6. baseplate reinforcing bar.
【Specific embodiment】
Refer to shown in Figure of description 1, the present invention is a kind of foundation ditch uplift pile and the waterproof connecting structure of structure base slab
Construction method, including following construction procedure：
(1) soil body construction at pile crown：The setting a diameter of D of uplift pile, cushion thickness is d, and waterproof material thickness is 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, digs depth and isAlso
It is tiltedly to dig to below structure base slab lower surface absolute altitudePlace, is taken as integer during construction, the face tiltedly dug out is
The side of rounding stage body.Reverse frustoconic is poured can protect baseplate reinforcing bar not to be etched, and prevent from being led because pile head waterproofing is improper
The base plate infiltration of cause.
(2) cushion construction：When carrying out structure base slab with the construction of underlayer, same construction thickness is d's around pile crown
Bed course, bed course is constructed around pile body with 45 degree of inclination angles at pile crown.
(3) pile crown amputation：Pile crown is amputated to structure base slab lower surface absolute altitude at D/4, and waterproof construction and cleaning
Basic unit, basic unit's debris, dust, lime-ash are cleaned up, basic unit's acceptance(check)；Wherein, waterproof construction need not be carried out at pile crown
The complicated operational procedures such as sealing rod, waterstop and fluid sealant construction, need to only use with the same waterproof of other parts under base 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 thickness is h；
(5) assembling reinforcement：Binding structure baseplate reinforcing bar, by the Reinforcement at resistance to plucking pile head and structure base slab master
Muscle is connected in a welding manner；
(6) concreting：To locate around structure base slab and pile crown rest pour jointly to be formed one it is unified mixed
Solidifying soil is overall, and the concrete poured below structure base slab lower surface absolute altitude is highly exactly D.
The present invention certain below uplift pile base plate lower surface absolute altitude by pile crown by will amputate a part pile crown more
Distance, while the concrete poured at pile crown, pile crown surrounding concrete and structure base slab are poured jointly more, is ensureing resistance to plucking
Under the early stage of the uplift effect of stake resistance to plucking, the concrete for pouring more is wrapped in pile crown and can improve uplift pile and structure base slab junction
Water resistance.
Specific embodiment above is only the preferred embodiment of this creation, is not used to limit this creation, all in this wound
Any modification, equivalent substitution and improvements for being done etc. within the spirit and principle of work, should be included in this creation protection domain it
It is interior.
