Description

Prestressed concrete dredges the construction method of muscle stake
Technical field
The present invention relates to the realm of building construction, specifically refers to that prestressed concrete dredges muscle stake.
Background technology
Prestressed concrete dredges muscle stake, and especially prestressed concrete quadrate tee section reinforcement composite foundation dredges muscle stake, fits For coastal area, river entrance, a large amount of beach, and in area, level of ground water is higher, the mud that low intensity, compressibility are higher Matter, silty clay.There are a large amount of miscellaneous fills, filling soil in these places and have mechanism humus soil equal distribution.Soft damage engineering is combined Foundation stake substitutes traditional compacted effect, plain concrete pile and steel concrete-pile, but bearing power increase amplitude is all very low, By multi-party research, by more than, several engineering methods are used in combination, and form composite pile, plain concrete core or armored concrete footpath core cement Native stake, cement sandstone composite pile, although avoid the shortcoming of respective engineering method and there is respective engineering method a little, quality has very big Improve so as to which intensity density is all greatly improved, but single pile bearing is only capable of using as composite pile.Construction is extremely difficult, takes When take a lot of work, high labor intensive, project progress are extremely slow, waste of materials, noise, dust, sewage be all difficult control, have a strong impact on The raising of Business Economic Benefit.
The content of the invention
The present invention is solution above-mentioned technical problem, there is provided a kind of prestressed concrete dredges muscle stake and its construction method.
Prestressed concrete dredges muscle stake, and including pile body, pile top and pile body, pile body includes stake, middle stake and lower stake, described Upper stake lower end is provided with dowel, is provided with jack at the top of lower stake, the surrounding in the thin muscle stake section, be furnished with four symmetrically lay it is pre- Stress cage bar, the upper end both sides of the thin muscle stake are provided with suspension ring.
In the present invention, the thin muscle stake is hollow.
In the present invention, the thin muscle stake section is square or rectangle.
In the present invention, the pile top is steel pile tip or concrete prefabricated pile top.
In the present invention, it is described anchor stake using epoxy resin configuration high performance structure adhesive perfusion anchor hole, dowel, be anchored and Into.
Wherein, pile top is shaper making, and is furnished with dowel, stirrup, construction muscle, and heterotype steel plate is welded by pile top Place's outer layer stirrup, intensive colligation are firm.
In the present invention, the pile body is elongated hollow, and thickness is not less than 60mm-120mm.
In the present invention, the jack is screwed hole, and anchor hole is screwed hole, and dowel is rod iron.
In the present invention, the thin muscle stake does not set pile body stirrup, and concrete is C20-C30.
In the present invention, the thin muscle stake is hollow square pile, and hollow square pile molding filled using extruder, drawing-die tube drawing, capsule Gas(Water)Molding.
Prestressed concrete in the present invention dredges the construction method of muscle stake, and square pile is transported to a potential field ground first in order, Prestressed concrete quadrate tee section reinforcement composite pile is steadily vertically sling, insertion stake position, carries out leveling, vertical piling construction, Anhydrous stake top screw thread anchor hole, dowel, stake top face is cleaned when stake top is apart from ground 1-1.2 rice height, irrigates the ring for having configured Oxygen tree fat structure glue, and steadily vertically sling in the lower piled anchor muscle hole of upper piled anchor muscle insertion, in this process, timely adjustment side Pile verticality, 1.5 ‰ that horizontal departure can not be long more than stake, after epoxide-resin glue solidification reaches intensity requirement, can be continued Piling construction.

Specific embodiment
With reference to embodiments illustrating the present invention.
Embodiment 1.
Prestressed concrete dredges muscle stake, and including pile body, pile top and pile body, pile body includes stake, middle stake and lower stake, described Upper stake lower end is provided with dowel, is provided with screw thread anchor hole at the top of lower stake, and the surrounding in the thin muscle stake section is furnished with four and symmetrically lays Prestressing force cage bar, the upper end both sides of the thin muscle stake are provided with suspension ring.The thin muscle stake is hollow.Pile top is steel pile tip.Institute Stating anchor stake uses epoxy resin configuration high performance structure adhesive perfusion anchor hole, dowel, anchor to form.Pile body is elongated hollow, thickness Spend for 120mm.Jack is screwed hole.The thin muscle stake does not set pile body stirrup, and concrete is C20.The thin muscle stake is hollow side Stake, hollow square pile molding adopt extruder, drawing-die tube drawing, capsule inflation.
When construction, first prestressed concrete quadrate tee section reinforcement composite pile is steadily vertically sling, insert stake Position, carries out leveling, vertical piling construction, when stake top is apart from ground 1-1.2 rice height, will clean anhydrous stake top threaded anchor Hole, dowel, stake top face, irrigate the epoxy resin structural adhesive for having configured, and the lower piled anchor of upper piled anchor muscle insertion of steadily vertically being sling In muscle hole, in this process, timely adjustment square pile perpendicularity, 1.5 ‰ that horizontal departure can not be long more than stake, works as epoxy resin After gelling reaches intensity requirement admittedly, piling construction can be continued.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto, Any those familiar with the art in the technical scope of present disclosure, technology according to the present invention scheme and its Inventive concept equivalent or change in addition, should all be included within the scope of the present invention.
