Description
Technical field
The present invention relates to the realm of building construction, is primarily referred to as a kind of occlusion water-seal pile and its construction method.
Background technology
In engineering construction field, with being on the increase for high-rise, construction of super highrise building, on civil building engineering and ground
Lower engineering excavation field, in river entrance, a large amount of beach, area, level of ground water is higher, low intensity, compressibility is higher, becomes silted up
The geology such as shale silty cohesive soil, a large amount of miscellaneous fill humus soils, important ask for deep pit digging supporting, sealing are one
Topic.Base pit engineering is an ancient tradition, and the construction method that slope is excavated and simple timber is gone along with sb. to guard him, the Contemporary Architecture that is far from suitable are applied
The needs of work, its construction speed are slow, of poor quality, poor stability, and cost is high, pollution weight, waste goods, materials and equipments.At present at home and abroad, ground
In the supporting of ironworker's journey and skyscraper foundation ditch, adopt hole-drilling interlocking pile more, though obtain successful experience, excavation, supporting,
How more to save, rapidly and efficiently, rationally in this problem, need further to study, inquire into.In current building excavation, supporting
It is in engineering to adopt drill-pouring concrete interlocking pile more, although this interlocking pile can meet construction needs to a certain extent,
But its difficulty of construction is larger, multiple stage boring machine and a large amount of difference bore steel thimbles is such as needed, has very big restriction, steel reinforcement cage to stake footpath
Making more bother, and easily deformation, displacement.During concrete perfusion, it is difficult to control.Meanwhile, concrete coagulation
The required time is longer, after interlocking pile pile, easily causes undergauge, and spillage, dew muscle, honeycomb, pitted skin, cage bar protective layer thickness are difficult
Ensure, ultimately result in leak.The perpendicularity of interlocking pile is also difficult to reach design requirement.Steel reinforcement cage pole when concrete is poured into a mould
Easily float, have a strong impact on construction quality.And in construction underground excavation field, the supporting of big foundation ditch, sealing, due to construction speed too
Slowly, whole building project progress is had a strong impact on, expectability is not completed to make engineering, very big economic loss is caused to enterprise, affect
The raising of Business Economic Benefit.
The content of the invention
To solve above-mentioned technical problem, the present invention provides technical scheme below：
In the present invention, supporting biconvex semicircle is engaged water-seal pile, including pile body and pile top, and pile top is provided with dowel and construction muscle,
Pile body includes epimere stake, stage casing stake and hypomere stake, and the stake top of epimere stake is provided with pile cover and construction muscle, and the lower end of epimere stake is provided with anchor
Muscle；The upper end of stage casing stake is provided with screw thread anchor hole, and the lower end of stage casing stake is provided with dowel；The upper end of hypomere stake is provided with screw thread anchor hole, under
The hypomere of section stake is provided with pile top；The both sides of the biconvex semicircle occlusion water-seal pile are that biconvex is semicircle.
The biconvex semicircle is semicircle or circular arc, projecting surface at least one.
In the present invention, the biconvex semicircle occlusion water-seal pile is prestressing force or half prestressing force or non-prestressed, and internal is real
The heart is hollow, and pile body section is square or rectangle, and pile top is concrete or steel.
In the present invention, the pile body both sides of the biconvex semicircle occlusion water-seal pile are provided with convex-concave enterprise tenon, and charity reinforcement；Institute
State biconvex semicircle and be provided with certain angle, its enterprise's tenon is oblique.
In the present invention, with pile body moulding by casting, concavo-convex position is provided with the impervious sealing of expansion and resists for dowel, distributing bar, pile top
Corrosion High Pressure Reinforced Concrete irrigates conduit mouth.
In the present invention, the semicircle symmetrical side or sides adjacent for being engaged water-seal pile respectively in biconvex semicircle of the biconvex.
In the present invention, the biconvex semicircle water-seal pile also includes edge shape end plate, and the edge shape end plate is metallic plate, is hit exactly
There is the centre bore corresponding with the occlusion water-seal pile size, the profile for inlaying shape end plate is water-seal pile cross section phase to be engaged with described
Same biconvex is semicircle；The anchor hole of one week uniform charity respective numbers of edgewise on the edge shape end plate；Under the edge shape end plate
The reinforcing bar of end charity respective numbers.
In the present invention, the biconvex semicircle water-seal pile also includes pile crown plate, and the pile crown plate includes base plate, in base plate
Some reinforced holes are formed around, pile extension anchor hole on the inside of reinforced hole, is provided with, the base plate is that biconvex is semicircle, outside the base plate
Roll over upwards on edge.
In the present invention, the cross section of the mould is to be engaged water-seal pile cross section identical biconvex semicircle with described.
In the present invention, the bossing should be supported the use with reeded stake is set, and projection width be less than it is recessed
Enter part, projection length is less than recess.
In the present invention, on the occlusion water-seal pile, pile extension can be carried out by the mode such as joint bar anchor or steel plate welding,
Extend pile body length.
Additionally, dowel length is less than dowel jack depth 15-25mm.
In pile crown plate, the angle between the base plate and outer is 100-130 degree.
The construction method of the interlocking pile in the present invention, first by the occlusion lower stake top face of water-seal pile, screw thread anchor hole, under
End is anchored rebar surface and cleans up, and after accumulated water, drying are anhydrous, then the occlusion water-seal pile is vertically steadily sling, then inserts
Enter the occlusion water-seal pile position, carry out leveling, vertical, piling construction；In work progress, supporting occlusion water-seal pile is adjusted at any time
Horizontal and vertical degree, reach standard require after, will occlusion sealing sunk pile complete；After the completion of pile sinking, sealing is engaged by two
Stake enterprise's tenon mouth and gap leveling, vertical, closing, while will clean out at grouting pipe, with expansion, water-tight concrete pressurization light
Post, tight closure enterprise tenon mouth sealing.
Wherein, the supporting is engaged sealing sunk pile, need stake upper end far from ground 1-1.2 rice when, first by stake upper end
Bundle rigid plastics cloth is peripherally enclosed, and colligation is firmly, then epoxy resin structural adhesive is poured in supporting occlusion water-seal pile upper end, when
After glue is covered with stake top anchor hole, stake vertically will steadily sling thereon, make the lower piled anchor hole of dowel alignment, smooth vertical insertion, leveling,
Vertically, check meet stake after, pile sinking is completed, whne when solidify.
Wherein, first, interlocking pile is vertically steadily sling；Interlocking pile position is inserted into, leveling, vertical, pile sinking is carried out and is applied
Work, adjusts the perpendicularity of interlocking pile in pile driving process at any time, pinpoints the problems, and reaches first after standard is required
Occlusion sunk pile is completed；After the completion of pile sinking, two interlocking piles, tongue and grooves are irrigated, high efficiency composition microlith, mortar concrete are tight
Occlusion is closed in sealing, and tongue and groove carries out sealing.
Occlusion water-seal pile specification：
