Description
Technical field
Construction structure is the utility model is related to, the pre- of more particularly to a kind of new polygon (by taking hexagon as an example) should
The construction design method of power hollow pile.
Background technology
Among in China, current pile foundation is built, prestressing force circle pile pile and hollow pile are widely used in all kinds of buildings
Strengthening of foundation in, prestressing force circle pile pile can be divided into post-tensioned prestressing stake and pretensioned-prestressed tube pile.Pre-tensioning system is pre-
Stress pile pile is using a kind of prefabricated structure of hollow cylinder elongate concrete made of pretensioned prestressing technique and centrifugal casting
Part, is mainly made of cylindrical shape pile body, end plate and steel hoop etc..The major defect of this pile body be with the frictional force of the soil body compared with
It is small, it is impossible to meet actual demand, with technological progress, the application of prestressed pile is more and more extensive, in identical concreting
In the case of amount, the surface area of the polygon pre-stress hollow stake bigger compared with circular pile pile with cross sectional moment of inertia, therefore pile body
Bearing capacity is improved, but the frictional force between its pile body and soil is still insufficient for actual construction needs.
Meanwhile common hollow pile appearance layer concrete unusual light, under the higher soil body environment of water content, due to
Stake, the extrusion stress of Soil Interface are maximum, and the excess pore water pressure of generation is also maximum, thus can be in cohesive strength minimum stake, pedosphere
So-called " moisture film " is formed on face, this can cause between stake soil, and there are certain lubricating action to reduce frictional resistance, thereby reduces
The bearing capacity of pile body does not reach design requirement, this stake for frictional resistance type is can not be ignored the problem of
For above-mentioned deficiency, the utility model is improved on the basis of original square hollow pile, is improved by designing,
The side friction of pile body is enhanced, while drainage channel and draining hole are set in pile body, by the pore water of pile body surrounding soil
It is drained into time inside hollow pile body, promotes pile body surrounding soil that discharging consolidation occurs, strengthens the intensity of whole region ground, this
Outside, the design of the utility model, which can play, reduces cost, improves efficiency and environmentally protective effect.
Utility model content
The purpose of the utility model is to overcome deficiency of the prior art, there is provided a kind of new polygon pre-stress hollow
Stake.
The purpose of this utility model is achieved through the following technical solutions.This new polygon pre-stress hollow stake,
Including pile body, the pile body includes trapezoidal protrusion and polygon pile body, and the trapezoidal protrusion section is hexagon, described trapezoidal prominent
It is trapezium structure to play side, is led in the trapezoidal protrusion inside, the polygonal pile is described polygon as hollow hexagonal prisms structure
Shape pile body section is hexagon, and two sections up and down of the trapezoidal protrusion are connected with polygon pile body respectively；It is described more
Side shape pile body includes internal face and outside wall surface, if being uniformly distributed the vertical pile body rhone in arterial highway, the stake in the outside wall surface
The lower end of body rhone is equipped with horizontal translot, and point is equipped with rectangular drain hole centered on the center of horizontal translot.
As preferred：The length of the pile body rhone is 5m -8m.
As preferred：The spacing of the equally distributed pile body rhone is 50mm -100mm.
As preferred：The material of body of a pile uses armored concrete or plain concrete.
The beneficial effects of the utility model are：
(1) the utility model is set by the pile body rhone of outside wall surface and the optimization polygon pile body at rectangular drain hole
Meter, can cause the pore water in pile body surrounding soil be discharged to as quickly as possible pile body it is hollow in, considerably increase draining
Passage, to accelerating surrounding soil drainage rates and accelerating soil solidifying to have obvious effect, and then can improve soil mass property, carry
High bearing capacity of pile, reduces the probability that pile body is damaged accident generation, increases economic efficiency.
(2) integrated design that the utility model passes through trapezoidal protrusion and polygon pile body so that pile body and surrounding soil
Contact area further increase, frictional behaviour improves, and greatly strengthen the bearing capacity of this kind of friction pile, reduces construction investment.

Description of reference numerals：It is pile body 1, trapezoidal protrusion 2, polygon pile body 3, pile body rhone 4, rectangular drain hole 5, interior
Wall 6, outside wall surface 7, horizontal translot 8.
Embodiment
The utility model is described further with reference to embodiment.The explanation of following embodiments is only intended to help and manages
Solve the utility model.It should be pointed out that for those skilled in the art, the utility model principle is not being departed from
On the premise of, some improvement and modification can also be carried out to the utility model, these are improved and modification also falls into the utility model
In scope of the claims.
As shown in Figure 1 to Figure 3, the new polygon pre-stress hollow stake includes pile body 1, trapezoidal protrusion 2, polygonal pile
Body 3, pile body rhone 4, rectangular drain hole 5, internal face 6, outside wall surface 7 and horizontal translot 8.The pile body 1 is mixed using reinforcing bar
Solidifying soil or plain concrete manufacture, the pile body 1 are made of trapezoidal protrusion 2 and polygon pile body 3, the section of the trapezoidal protrusion 2
For hexagon, side is trapezium structure, is led in internal, the polygon pile body 3 is hollow hexagonal prisms structure, and section is six sides
Shape, two sections up and down of the trapezoidal protrusion 2 are connected with polygon pile body 3 respectively.The polygon pile body 3 includes interior
Wall 6 and outside wall surface 7, if being uniformly distributed the vertical pile body rhone 4 in arterial highway, the per pass pile body draining in the outside wall surface 7
The length of groove 4 is 5m -8m, and spacing is 50mm -100mm, and depth 5mm, the lower end of the pile body rhone 4 is equipped with horizontal horizontal stroke
Groove 8, point sets a rectangular drain hole 5 centered on the center of horizontal translot 8, and the size at rectangular drain hole 5 is a length of
50mm, width 20mm.
Pile body 1 is embedded in the soil body, and the pore water in surrounding soil passes through the pile body rhone 4 and square on polygon pile body 3
Shape draining hole 5 is flowed to inside hollow pile body 1, and polygon pile body 3 increases pile-soil interface product compared with circular pile pile, at the same time
Trapezoidal protrusion 2 further increase with soil body contact area, enhance the side friction of polygon pile body 3, furthermore pile body draining
Groove 4 and rectangular drain hole 5 cause the drainage path of polygon pile body 3 to increase, and contribute to the draining of 1 surrounding soil of pile body to consolidate
Knot, lifts intensity and bearing capacity, while effectively reduces the lateral pressure that pile body 1 is subject to, so also just mitigate pile body 1 because by
Big lateral pressure causes the generation of the hidden danger such as broken pile, ensure that the stability of pile quality, lifting construction quality and reduction engineering
Cost.
