Abstract
The utility model relates to a novel abnormity cement soil pile. The cross section of a pile body is an abnormity cross section, and the abnormity cross section is in a rectangle, is formed by combining a middle rectangle and two round heads which are connected with both ends of the middle rectangle, or is in an X shape. The pile body can also be a mother pile, and a core pile with high intensity is inserted into the center of the mother pile to form a composite pile. The utility model solves the problem of low construction speed, low efficiency, and difficult guarantee of construction quality. The utility model can be widely used for composite foundation piles, penning piles, water seal curtain piles, etc. The utility model can also be used for the mother piles of cement soil composite piles with hollow cores, foundation piles, the penning piles and anti-lifting piles, and can be widely used for stratums, such as peaty soil, mud, etc., in which regular agitating piles and suspension spray piles can not be used. The utility model can raise the construction efficiency by more than one time, is convenient for overlapping, and guarantees the construction quality.
Description
Technical field
The utility model belongs to the pile in the building foundation construction, particularly a kind of novel special-shaped cement earth pile.Can be widely used in slope protection pile, water-stop curtain stake, compound foundation pile etc.Also can be applicable to female stake of stiff-core cement soil composite pile, be used for foundation pile, slope protection pile, uplift pile, and can be widely used in conventional agitation piles such as peat soil, mud, an outstanding spray stratum that can not be suitable for.
Background technology
Cement mixing method is because its easy construction, with low cost, and is widely used in fields such as ground processing, pattern foundation pit supporting structure and water-stop curtain stake, but agitation pile is used for peat soil, mud stratum, but is subjected to very big restriction.The cross section of existing cement mixing method is generally circle, its diameter often is 400～800mm, as as the curtain pile sealing, both sides adopt reinforced concrete revetment pile tangent with it, effectively pile spacing is generally 200～600mm, and efficient is low, and speed of application is slow, in order to reduce the pattern foundation pit supporting structure cost two circle stakes can be set between two reinforced concrete revetment piles, and construction quality is difficult for guaranteeing.
Summary of the invention
The purpose of this utility model just provides a kind of novel special-shaped cement earth pile, and slow with the speed of application that the solution prior art exists, efficient is low, and construction quality is difficult for the problem of assurance.
In order to address the above problem, the technical scheme that the utility model is taked is: the cross section of this abnormal shape cement earth pile is an odd-shaped cross section, and the shape of this odd-shaped cross section comprises rectangle, combined or X-shaped by the rectangle of centre and two round ends being connected these rectangle two ends.
The diameter of described round end is more than or equal to the width of connected square-section.
The female stake of described pile body is at central authorities' insertion high strength core stake formation composite pile of this mother's stake.
Described female stake cross section is circular or square; Described core stake is an X-shaped, is made by concrete.Comprise in per 1 cubic metre of the described material of body of a pile: cement 150～400kg, good soil 600～900kg, aggregate chips 200～500kg, flyash 50～150kg, accelerating admixture (1～3) %.
Also comprise early strength admixture,, shorten time of setting to improve its early strength.
Described cement can adopt Portland cement, portland slag cement or pulverized fuel ash cement; Good soil can be silt, cohesive soil or sand; Aggregate chips is the byproduct of stone sorting, is used for regulating the proportion and the intensity of cement-soil mix; Flyash has the low strength cement effect, improves the pumpability of mix simultaneously; The accelerating admixture effect is to promote the mix rapid solidification, and improves its early strength.
The cement earth pile of employing the utility model cross section structure can be designed to length and reach 800～1600mm, has increased by one times than prior art, effectively improves efficiency of construction, saves the whole cost of supporting, and construction quality is protected.This prescription can effectively be controlled time of setting, control final strength, control slurry specific gravity.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.

The specific embodiment
Referring to Fig. 1～Fig. 3, the common feature of the pile body 1 in these three kinds of cross sections is the width that increased pile body, can improve efficiency of construction.
Referring to Fig. 4, when handling stake as ground, this embodiment can under the prerequisite that does not increase even reduce material usage, increase the pile body side surface area of pile body 1, and the bearing capacity of stake can improve 20%～50%.
Referring to Fig. 5 and Fig. 6, the central authorities' insertion high strength core stake 2 formation composite piles at cement earth pile 1 (female stake) are used for ground and handle.Wherein the core stake 2 of X-shaped is the strength core, can be concrete pile or preformed pile, increases overall intensity.
The basic recipe of the pile body of cement earth pile of the present utility model (in per 1 cubic metre) is: cement 150～400kg, good soil 600～900kg, aggregate chips 200～500kg, flyash 50～150kg, accelerating admixture 1～3%.
Wherein cement can adopt Portland cement, portland slag cement or pulverized fuel ash cement etc.; Good soil can be silt, cohesive soil or sand etc.; Aggregate chips is the byproduct of stone sorting, is used for regulating the proportion and the intensity of cement-soil mix; Flyash has the low strength cement effect, improves the pumpability of mix simultaneously; The accelerating admixture effect is to promote the mix rapid solidification, and improves its early strength.Add early strength admixture in case of necessity,, shorten time of setting to improve its early strength.This prescription can effectively be controlled time of setting, control final strength, control slurry specific gravity.
This new type cement soil pile can be applied to foundation pit supporting pile, water-stop curtain stake and compound foundation pile, also can be applicable to female stake of stiff-core cement soil composite pile, be used for foundation pile, slope protection pile, uplift pile, and can be widely used in the stratum that conventional agitation piles such as peat soil, mud can not be suitable for.Its advantage is that more conventional circular pile efficient is enhanced about more than once when being used as curtain pile, and overlap joint is convenient simultaneously, can guarantee the lapping construction quality, and whole support cost can reduce more than 20%.Effectively improve efficiency of construction, save the whole cost of supporting, construction quality is protected.
