Abstract
The utility model relates to an internal expansion type miniature concrete pile. According to the internal expansion type miniature concrete pile, the bottom end of a left half ring concrete column and the bottom end of a right half ring concrete column are hinged through a hinge, a threaded rod penetrates through the top end of the left half ring concrete column and the top end of the right half ring concrete column, and nuts are screwed at the two ends of the threaded rod. A concrete pile cap can be cast in an opening of the top end of the left half ring concrete column and the top end of the right half ring concrete column on site. According to the internal expansion type miniature concrete pile, by dividing the pile into two half rings, the self-expansion purpose of the pile body is achieved; a traditional pile driving mode is abandoned by the pile, a pit digging and pre-burying mode is adopted, and the effect that the pile body is not damaged in the construction process is achieved; a unique threaded rod expansion method is adopted for the pile, self-expansion of the pile body is achieved through internal extrusion, and thus sinking accidents are prevented.
Description
Technical field
The utility model relates to the miniature concrete pile of a kind of inner intumescence type.
Background technology
Foundation settlement refers to foundation soil densification and the foundation surface that causes sinks under subsidiary stress effect.Excessive sedimentation, particularly differential settlement, can make building run-off the straight, cracking so that can not normally use.Before building and earth structure are built, in ground, exist already the selfweight stress being caused by soil body self gravitation.Building and earth structure load pass to ground by the bottom surface of basis or embankment, the original stress state of natural soil layer is changed, under additional three-dimensional stress component effect, in ground, produced vertical, side direction and shear strain, cause the vertical and lateral displacement of each point.The vertical deformation of foundation surface is called foundation settlement, or foundation settlement.Due to building load difference and the reason such as ground is inhomogeneous, the sedimentation of basis or embankment each several part is more or less always inhomogeneous, makes correspondingly to produce extra stress and distortion among superstructure or road structure.Uneven settlement of foundation has surpassed certain limit, to cause the cracking of building, crooked even destruction, such as brick wall, occur that crack, crane wheel occur card rail or slide rail, towering structure inclination, rotary shaft of machine deflection, depart from pier, beam face or pavement cracking etc. with the fracture of building connecting pipe and bridge.The sedimentation that building lot produces under action of long-term load, its final settlement can be divided into three parts: initial settlement (or claiming immediate settlement), primary consolidation sedimentation and secondary consolidation settlement.Initial settlement claims again immediate settlement, refer to the moment that outer lotus adds, the sedimentation that saturated soft soil pore water occurs while still having little time to discharge, only there is deformation and do not have body to become in the soil body now, generally this distortion is referred to as to shear strain, by elastic deformation, calculates.Load application on saturated soft clay foundation, especially as interim or live load account for warehouse, the oil tank of very large proportion and be subject to the high-rise structures etc. of wind load, the initial settlement amount causing therefrom will account for the considerable part of total settlement, should give estimation.
The method generally conventionally adopting for foundation settlement is: piling.Some highrise buildings, by piling, then pour into a pile foundation by many piles and realize and prevent its sedimentation.But for the basis of some little shapes, such as the platform of marking time, generally can not drive piles, but the time one is of a specified duration, is just easy to occur sedimentation.
Summary of the invention
The purpose of this utility model is to provide the miniature concrete pile of a kind of inner intumescence type, thus can realize for one slightly the basis of shape also can implement piling.
To achieve the above object, the utility model adopts following technical scheme: the miniature concrete pile of a kind of inner intumescence type, its structure mainly comprises: left semicircle ring concrete post, right semi-circle ring concrete post, hinge, screw rod, nut, described left semicircle ring concrete post, right semi-circle ring concrete post bottom are hinged by hinge, one place, top is penetrated with screw rod, and described screw rod two ends are screwed with nut; Described left semicircle ring concrete post, right semi-circle ring concrete capital end opening position can cast-in-situ concrete pile cap.
In above-mentioned left semicircle ring concrete post, right semi-circle ring concrete post, be filled with building backfill.
Above-mentioned screw rod, nut are wrapped with concrete coating.
The beneficial effects of the utility model: by by stake to cuing open into two semicircular ring, realized the object of pile body self-expanding; This pattern of abandoning traditional piling, has adopted the pre-buried mode of digging pit, and has reached the effect of not destroying pile body in work progress; Stake has adopted unique screw expansion method, has realized pile body self inflation, thereby prevent the generation of subsidence accident by interior extruding.
Accompanying drawing explanation
Fig. 1 is the structural representation of the miniature concrete pile of a kind of inner intumescence type of the utility model.
1-left semicircle ring concrete post in figure, 2-right semi-circle ring concrete post, 3-hinge, 4-screw rod, 5-nut, 6-pile cap, 7-builds backfill.
The specific embodiment
Below in conjunction with 1 pair of specific embodiment of the present utility model of accompanying drawing, make a detailed explanation.
Embodiment: the miniature concrete pile of a kind of inner intumescence type, its structure mainly comprises: left semicircle ring concrete post 1, right semi-circle ring concrete post 2, hinge 3, screw rod 4, nut 5, described left semicircle ring concrete post 1, right semi-circle ring concrete post 2 bottoms are hinged by hinge 3, one place, top is penetrated with screw rod 4, and described screw rod 4 two ends are screwed with nut 5; Described left semicircle ring concrete post 1, right semi-circle ring concrete post 2 top end opening positions can cast-in-situ concrete pile cap 6.
In described left semicircle ring concrete post 1, right semi-circle ring concrete post 2, be filled with building backfill 7.
Described screw rod 4, nut 5 are wrapped with concrete coating.
The miniature concrete pile of this inner intumescence type, is first by the mode of pre-earth excavation, to drive piles, and screw rod 4, nut 5 have played the function that regulates aperture position size, so that the design size of coupling cast-in-situ concrete pile cap 6.
The utility model is so realization: first in the place of needs piling, dig the heatable adobe sleeping platform of a back taper, if the weight of left semicircle ring concrete post 1, right semi-circle ring concrete post 2 is large, can put it in hole by loop wheel machine; Then building backfill 7 is poured in the place of semicircular ring concrete post 1, right semi-circle ring concrete post 2 indents into left, fills rear employing rammer compacter and tamps; Then some concrete mortars of premixing, cover screw rod 4, nut 5 parts with concrete mortar.Complete after above-mentioned steps, then pour into a mould cast-in-situ concrete pile cap 6.
Because this concrete pile is back taper, cast-in-situ concrete pile cap 6 is integral after pouring into a mould with left semicircle ring concrete post 1, right semi-circle ring concrete post 2, once sinking appears in stake, the cast-in-situ concrete pile cap 6 of top large volume is enough to be held, because stake of the present utility model is not prone to sinking.
Embodiment of the present utility model, is to take that the step of building body is subjects, is therefore not limited to the application of step sedimentation.
