Description
Technical field
This utility model belongs to foundation engineering field, a kind of can be self-align for cast-in-situ bored pile steel pile casting.
Background technology
At present in the lengthening casing construction of cast-in-situ bored pile, it is the control stress point in always construction and difficult point to lengthening casing location and perpendicularity.Lengthening before casing sets every time, be required to first carry out positioning adjust perpendicularity again, then carried out setting of casing by vibration hammer, to position casing frequently and perpendicularity is corrected, complex procedures in work progress, efficiency is slow, time-consuming takes a lot of work.And owing to casing is longer, it is difficult to accurately the first location of casing is fixed and buried underground, and also is difficult to control the perpendicularity of casing during setting, bury the time underground longer.
Utility model content
The purpose of this utility model is to provide a kind of self-align steel pile casting, solve to lengthen during casing sets the technical problem that pile quality cannot ensure and construction speed is slower positioning slowly, frequently carrying out perpendicularity rectification, later stage pile body.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of self-align steel pile casting, including cylinder, described cylinder by guiding urceolus and going along with sb. to guard him the double layer sleeve barrel that inner core is vertically socketed and the vertical keeper arranged between the two forms, described in go along with sb. to guard him inner core and be longer than guiding urceolus,
The inwall of described guiding urceolus one week uniformly connects one group of keeper, and it is the most equal that all keepers are oppositely oriented the size that the inwall of urceolus protrudes to center, described in go along with sb. to guard him the inner surface of the outer wall all keepers of socket of inner core.
Described keeper is reinforcing bar, steel pipe or the shaped steel along the elongated connection of inwall guiding urceolus.
Described keeper is uniformly provided with 3-8 road in one week along the inwall guiding urceolus.
The casing length of described guiding urceolus and the ratio of diameter are not less than 2.
It is 20mm-30mm that described keeper is oppositely oriented the size that the inwall of urceolus protrudes to center.
Compared with prior art this utility model has the characteristics that and beneficial effect:
This utility model mainly solves to position slowly and frequently carry out perpendicularity during lengthening casing sets corrects problem, is obviously improved the pile quality and construction speed ensureing pile body.This utility model is to design a kind of double layer sleeve barrel that can be self-align, go along with sb. to guard him inner core length short, position and perpendicularity is corrected more convenient, gone along with sb. to guard him skew and the perpendicularity inclination of inner core by the keeper restriction arranged on inwall, reduce location and perpendicularity rectification frequently in work progress.Guide urceolus shorter, easily carry out the location of stake position and the control of perpendicularity, guide after urceolus has been buried underground and can go along with sb. to guard him the location of inner core and bury underground by carrying out quickly.
This utility model cost is low, and using method is simple, efficiency is high, time and labour saving, it is possible to be accurately controlled stake position, it is ensured that the perpendicularity of construction in later period pile body.

Detailed description of the invention
Embodiment sees shown in Fig. 1-2, a kind of self-align steel pile casting, including cylinder, described cylinder is by guiding urceolus 1 and going along with sb. to guard him the double layer sleeve barrel that inner core 2 is vertically socketed and the vertical keeper 3 arranged between the two forms, described inner core 2 of going along with sb. to guard him is longer than guiding urceolus 1, the present embodiment is gone along with sb. to guard him inner core 2 than guiding the long 1m-2m of urceolus 1, guide the internal diameter of urceolus 1 than the big 1cm of external diameter going along with sb. to guard him inner core 2, it is ensured that gap between the two.
It is the most equal that the inwall of described guiding urceolus 1 uniformly connects the size that the inwall having one group of keeper 3, all keepers 3 to be oppositely oriented urceolus 1 protrudes to center for one week, described in go along with sb. to guard him the outer wall of inner core 2 and be socketed the inner surface of all keepers 3,
Described keeper 3 is reinforcing bar, steel pipe or the shaped steel along the elongated connection of inwall guiding urceolus 1.This example is reinforcing bar, a diameter of 2.5cm.
Described keeper 3 is uniformly provided with 3-8 road in one week along the inwall guiding urceolus 1.The present embodiment is 4 roads.
The casing length of described guiding urceolus 1 and the ratio of diameter are not less than 2.
It is 20mm-30mm that described keeper 3 is oppositely oriented the size that the inwall of urceolus protrudes to center.
Work progress of the present utility model is as follows:
Step one, determines the position of cast-in-situ bored pile, and the position of measurement and positioning fender post before construction.
Step 2, shown in Figure 3, in the stake holes of ground less than 4, pre-buried inwall connects the guiding urceolus having keeper, and guide urceolus buries needs underground accurately, it is ensured that the center of short casing and stake position center superposition, and ensure to guide the perpendicularity of urceolus, guide protective tube location and perpendicularity directly influence and lengthen burying underground of casing, and guide protective tube can use rotary drilling rig or excavator to bury underground, human assistance location and adjustment perpendicularity, because casing is shorter, it is easier to carry out positioning and degree control.
Step 3, sees shown in Fig. 4-5, will go along with sb. to guard him inner core and head in guiding urceolus, and correct perpendicularity during setting.Must guarantee during going along with sb. to guard him the burying underground of inner core to go along with sb. to guard him inner core not with keeper friction.Guiding urceolus owing to burying underground in advance has guide effect, goes along with sb. to guard him and can save location and straightening repeatedly before inner core sets, therefore during setting, perpendicularity rectification number of times also greatly reduces.
Step 4, goes along with sb. to guard him after inner core set, then extracts guiding urceolus.
