Description
Technical field
The utility model is related to a kind of threaded prefabricated U HPC pile tube.
Background technology
Especially differential settlement can cause originally hyperstatic structure to produce in very big time for the larger sedimentation of pile foundation
Power, the cracking for causing structure is even destroyed.Especially there is higher requirement to the anti-settling ability of pile foundation in soft clay area, for rubbing
It is long obtaining larger frictional resistance that wiping type stake generally requires to increase stake, thus considerably increases cost, the building on the water surface
Thing its stake is easily pulled up destruction by other function influences such as underground water, and it will also result in serious breaking to superstructure
It is bad, and the maintenance correction expense in later stage is highly difficult big.Only solid square pile, pile tube in traditional prefabricated pile, its intensity difference, no
Very big mechanical snap power and frictional resistance can be provided.Meanwhile, general prefabricated pile is frequently with static pressure method and the construction party of hammering method
Method, its Piling speed is relatively slow and construction can cause noise pollution.The sedimentation of existing stake pulls up the destruction that can cause superstructure,
And Piles for Friction Piles often needs to increase that stake is long ensureing enough native frictional resistances, so as to the increase of cost for causing.
Utility model content
The purpose of this utility model is to provide a kind of threaded prefabricated U HPC pile tube.
In order to solve above-mentioned technical problem, a kind of technical scheme of the present utility model is, a kind of threaded prefabricated U HPC
Pile tube, including pipe of concrete pile body, by pile cover, pile body, stake base cone, pile cover is arranged on pile body top, stake bottom to pipe of concrete pile body
Bore as back taper and be arranged on pile body bottom, pile body periphery is from top to bottom provided with spiral helicine concrete rib, concrete rib from
Stake base cone uniform pitch spirals and extends to pile cover, and concrete rib surface is provided with alloy-steel sheet.
Further, the alloy-steel sheet is wrapped in outside concrete rib, and alloy-steel sheet is connected by setscrew with pile body
Connect.
Further, the pipe of concrete pile body, concrete rib are ultra-high performance concrete and are made.
Further, the pipe of concrete pile body is provided with strengthening rib strip.
Compared with prior art, the utility model has the advantages that：Tube pile structure is simple, reasonable in design, intensity
It is good, the settlement issues of pile foundation are improved, using ultra-high performance concrete good fluidity, mold forming is easily propped up, the characteristics of intensity is high,
Make concrete rib that there is very high intensity, very big soil pressure can be born and be not subject to crushing, using the teaching of the invention it is possible to provide very big mechanical snap power
And frictional resistance, concrete rib surface parcel alloy-steel sheet, concrete rib is protected well, and make concrete tubular pile body image one
Awl with sword, beneficial to pile body forced piling construction is rotated, and greatly accelerates the Piling speed of such prefabricated pile.
With reference to the accompanying drawings and detailed description the utility model is described in more detail.

Specific embodiment
As shown in figure 1, a kind of threaded prefabricated U HPC pile tube, including pipe of concrete pile body, pipe of concrete pile body is by stake
Cap, pile body, stake base cone, pile cover is arranged on pile body top, and stake base cone is back taper and is arranged on pile body bottom, and pile body periphery is by upper
To spiral helicine concrete rib is arranged with, concrete rib is spiraled from stake base cone uniform pitch and extends to pile cover, concrete rib surface
Alloy-steel sheet is provided with, alloy-steel sheet can well protect concrete rib, and make one brill with sword of concrete tubular pile body image
Son.
In the present embodiment, the alloy-steel sheet is wrapped in outside concrete rib, and alloy-steel sheet is by setscrew and pile body
It is connected.
In the present embodiment, the pipe of concrete pile body, concrete rib are ultra-high performance concrete and are made.
In the present embodiment, the pipe of concrete pile body is provided with strengthening rib strip.
Construction method is made, is comprised the following steps：（1）It is prefabricated to pour mould：According to actual setting pipe of concrete pile body
Parameters, according to the specifically used situation and construction needs of pipe of concrete pile body, designing pile length, diameter, the spiral shell of concrete rib
Away from parameters such as, rib thickness, and mould is made according to parameter designing,；（2）Make pipe of concrete pile body：Superelevation is poured to mould is poured
Energy concrete for making pipe of concrete pile body, the mould that will complete to pour is placed on centrifuge, and using centrifuge the coagulation of mould is made
Native pile tube body does lasting circular motion is molded it, subsequently removes grinding tool and the pipe of concrete pile body to being molded carries out the later stage
It is steam-cured；（3）Parcel alloy-steel sheet：When pipe of concrete pile body intensity reaches requirement, punched on pipe of concrete pile body with electric hammer,
And alloy-steel sheet is wrapped up in concrete rib, alloy-steel sheet is anchored on pipe of concrete pile body with setscrew；（4）Piling：
Pile hammer is connected with pile crown, installation is sling, pile hammer to pile cover applies downward pressure, while pile hammer is rotated by itself
Drive pipe of concrete pile body to rotate, make pipe of concrete pile body quickly sink.
In the present embodiment, in step（2）In, it is to strengthen overall construction intensity according to actual strength needs, can first in mould
Strengthening rib strip is set in tool, then ultra-high performance concrete is being poured to whole in mould.
On be classified as preferred embodiment, the purpose of this utility model, technical scheme and advantage have been carried out further specifically
It is bright, should be understood that and the foregoing is only preferred embodiment of the present utility model, it is not new to limit this practicality
Type, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvements made etc. should be included in this
Within the protection domain of utility model.
