Abstract
The utility model relates to a prefabricated-tube composite pile of soil cement, composed of precast concrete pile pipes whose outer sides are enclosed by a soil cement slurry cylinder and whose inner sides are poured with cast-in-place concrete. The external diameter range of the precast concrete pile pipes is from 350 to 800 mm, the inside diameter range is from 200 to 600 mm, and the shapes can be circular tubes or rectangular tubes. In the course of construction, no noise is made, no mud is discharged, and no environmental pollution is produce when piling. The pile can enlarge the effective load bearing diameter of the pile pipe through composition, which, therefore, saves construction materials, reduces construction cost by 50% more or less, and overcomes the defect of unstable bored pile quality and the soil compaction effect produced by prefabricated piles, suitable to be used for buildings, bridge foundations, foundation pits, port engineering, etc.
Description
The utility model relates to a kind of construction work basic component.
At present, construction work stake commonly used has precast reinforced concrete piles and bored pile etc., generally form by the homogeneous materials of pile body and stake point, precast reinforced concrete piles produces noise when squeezing into, produce soil compaction effect in soft clay area, negative friction occurs, particularly be about about 40% of supporting capacity that the pile concrete material itself can provide, cause great waste in some its supporting capacitys of large-diameter concrete drilled pile of soft clay area riverine, coastal, along the lake; Bored pile generally needs mud off, and a stake pedosphere face produces the mud skin, the vertical bearing capacity of influence stake, and the mud contamination environment that work progress produces, and the pile quality of castinplace pile is difficult for guaranteeing, the phenomenon of necking down even broken pile often occurs.
Noiselessness when the purpose of this utility model provides a kind of squeezing into, no mud is discharged in the construction, and is free from environmental pollution, and can reduce the prefabricated pipe cement-soil composite pile of construction costs.
The technical scheme of the utility model prefabricated pipe cement-soil composite pile is: the pile body center is the precast concrete pile pipe, and its skin is that open column shape soil cement slurry cylinder, its internal layer are the cast-in-situ concrete cylinders.
Top in the above-mentioned precast concrete pile inner tube layer is the cast-in-situ concrete cylinder.
Above-mentioned precast concrete pile external diameter of pipe 350～800mm, internal diameter 200～600mm.
Above-mentioned precast concrete pile pipe is tubular or rectangular tube.
For improving bearing capacity, the precast concrete pile pipe can have collar flange on middle part or bottom external diameter.
Above-mentioned precast concrete pile pipe is long along stake can be the segmentation welding, also can be whole.
According to different situations, the cross section of precast concrete pile pipe can be to dwindle piecemeal or expansion piecemeal.
Production process of the present utility model is as follows: utilize conventional major diameter deep layer mixer or cartridge type soil-cement stirring to make the cement-soil of diameter 800-1200mm or the cartridge type soil cement slurry cylinder of back cover of band core (diameter 200-500mm).The precast concrete pile pipe is pressed in the soil cement slurry cylinder, and the precast concrete pile pipe can segmentation be implanted field Welding.Penetration concrete in the blank pipe of stake pipe top is finished the making of prefabricated pipe cement-soil composite pile.
The utility model has the advantages that: noiselessness when construction is squeezed into, no mud is discharged in the construction, and free from environmental pollution, this stake can effectively be carried the stake pipe diameter phi 350～800mm by the compound φ of being extended to 900～1200mm, thereby the saving constructional materials reduces construction costs about 50%; Overcome the soil compaction effect that unsettled shortcoming of drill-pouring quality of pile and preformed pile produce; Because the precast concrete pile pipe is prefabricated in the factory, therefore can reduce the workload of site operation, improve speed of application, shorten construction period.Be applicable to building, bridge foundation, pattern foundation pit supporting structure and port works etc.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the common shape of precast concrete pile pipe, adopts when cement-soil is in soft-plastic state.
Fig. 3 is the shape of band double-vane edge precast concrete pile pipe, at the bottom of being usually used in.
Fig. 4 is the shape of band edge of a wing precast concrete pile pipe, is at cement-soil and adopts when stream is moulded state.
Fig. 5, Fig. 6 are the precast concrete pile pipes of segmentation welding, the schematic diagram that its cross section dwindles piecemeal and enlarges piecemeal.
Embodiment: the pile body of prefabricated pipe cement-soil composite pile is to irritate cast-in-situ concrete 2 by precast concrete pile pipe 1 outsourcing soil cement slurry cylinder 3, in the blank pipe of precast concrete pile pipe top.The soil cement slurry cylinder can replace by lime soil paste cylinder, and water/binder ratio is determined according to soil layer classification and saturation ratio, is generally 0.6～1.5, external diameter 800～1000mm, internal diameter 200～500mm.The precast concrete pile external diameter of pipe is selected arbitrarily between 350～800mm, internal diameter is selected arbitrarily between 200～600mm, shape is round tube or rectangular tube, the precast concrete pile pipe can have collar flange 4 on middle part or bottom external diameter, long along stake can be the segmentation welding, also can be whole, its cross section can be to dwindle piecemeal or expansion piecemeal.
