Abstract
The invention relates to a mechanical drilling cast-in-place pile, and belongs to the technical field of burying of load boxes of the mechanical drilling cast-in-place piles. The mechanical drilling cast-in-place pile comprises the load box, wherein an upper section steel reinforcement cage and a lower section steel reinforcement cage are respectively connected with the upper end and the lower end of the load box; guide bars are welded between the upper section steel reinforcement cage and the load box; outer steel reinforcement cage stirrups are arranged on the outer rims of the upper section steel reinforcement cage and the lower section steel reinforcement cage; an annular plate is arranged at the lower end of the lower section steel reinforcement cage. The annular plate is additionally welded at the bottom end of the lower section steel reinforcement cage, so that the steel reinforcement cages and the load box can be kept at the center of a pile hole as much as possible during burying, and the phenomenon of higher data deflection of two lower displacement rods in a later detection process can be avoided.
Description
Technical field
The present invention relates to a kind of machine drilling castinplace pile, belong to the burying technology field of machine drilling castinplace pile load box.
Background technology
In recent years, since, along with the extensive use of machine drilling castinplace pile and self-rebound force balance loading case, when a large amount of machine drilling filling pile constructions is complete, the tapering being caused by engineering machinery drill bit all can be arranged at bottom.But, load box and reinforcing cage are in put procedure, reinforcing cage inserts in tapered hole bottom, cause reinforcing cage and the load box of whole pile body to tilt, cause in late detection process data inaccurate, even because causing concrete disintegrating etc. in pile body, discontinuity affects the situation of pile quality, and machine drilling castinplace pile load box top panel place is not welded with loudspeaker muscle (guiding rib), cause lead slurry pipe can not be smoothly in put procedure by load box middle part, directly by pouring concrete on load box top panel, pouring pressure is reduced and cause load box bottom sediment can not effectively clean out or pour into a mould leakiness etc.
Summary of the invention
In order to overcome above-mentioned defect, the object of the present invention is to provide a kind of machine drilling castinplace pile.
To achieve these goals, the present invention adopts following technical scheme:
A kind of machine drilling castinplace pile, it comprises a load box, epimere reinforcing cage is connected with the top and bottom of load box respectively with hypomere reinforcing cage, between epimere reinforcing cage and load box, is welded with guiding rib;
Outer rim at described epimere reinforcing cage and hypomere reinforcing cage is provided with stirrup outside reinforcing cage, is provided with annular slab in the lower end of described hypomere reinforcing cage.
The junction of epimere reinforcing cage and load box is provided with the auxiliary muscle in right angle.
Described guiding rib and load box angle are greater than or equal to 60 °.
Self-rebound force balance loading case is embedded in equalization point position, and hypomere reinforcing cage bottom needs to be welded with an annular slab, and the external diameter of annular slab is consistent with the outer stirrup diameter of reinforcing cage, while putting reinforcing cage and load box, is supported on the edge of bellmouth by annular slab, prevents from.
Beneficial effect of the present invention:
1, data accuracy improves:
Hypomere reinforcing cage bottom is welded with annular slab, can make reinforcing cage and load box in the time burying underground, remain on a center, hole as far as possible, can not cause 2 bottom offset bar data deviations excessive in late detection process.
2, construction technology is simple:
Get final product left-hand seat without carrying out special training, only the main muscle in hypomere reinforcing cage bottom need be welded on annular slab, diameter must equal outer stirrup diameter, connect and be positioned in stake with load box on request, in the middle of construction, there is no complicated technology content, only need to confirm pile No., check load box and outer dimension of hoop reinforcement.
3, construction quality is good:
Reinforcing cage bottom is welded with and when annular slab can effectively ensure because bury reinforcing cage and load box underground, tilts excessively, and load box, applying in active force process, causes pile body inside discontinuity, the situations such as concrete disintegrating.
4, cost is low:
Annular slab only need adopt diameter consistent with outer stirrup, and common sheet material, can solve the major issue that affects construction in later period progress and quality.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the installation site schematic diagram of the auxiliary muscle in the right angle in the present invention (6).
Detailed description of the invention
Describe the present invention below in conjunction with accompanying drawing 1,2:
A kind of machine drilling castinplace pile, it comprises a load box 1, epimere reinforcing cage 2 is connected with the top and bottom of load box 1 respectively with hypomere reinforcing cage 3, between epimere reinforcing cage 2 and load box 1, is welded with guiding rib 4;
Be provided with stirrup 5 outside reinforcing cage in described epimere reinforcing cage 2 and the outer rim of hypomere reinforcing cage 3, be provided with annular slab 7 in the lower end of described hypomere reinforcing cage 3.
Epimere reinforcing cage 2 is provided with the auxiliary muscle 6 in right angle with the junction of load box 1.Prevent from throwing off and dropping burying in process reinforcing cage and load box underground.
Described guiding rib 4 is greater than or equal to 60 ° with load box 1 angle.Object is that guiding grout pipe carries out secondary pile hole cleaning and cast by load box centre bore, plays booster action simultaneously.
Hypomere reinforcing cage is forbidden the welding that is connected with jack outside or epimere reinforcing cage.
Necessary smooth, the firm welding of annular slab that is welded on hypomere reinforcing cage bottom, can not cause distortion when welding.
When loudspeaker muscle (guiding rib) and reinforcing cage, load box are welded to each other, must firm welding, forbid the defects such as rosin joint, weldering are broken.
Loudspeaker muscle (guiding rib) must use the round steel of Φ 16 above diameters, and soldering angle must be greater than 60 °.
The main muscle end face in hypomere reinforcing cage bottom should ensure concordant.
Place self-rebound force balance loading case in pile foundation time, displacement detector need be with on fixation with steel wire reinforcing cage and every 1 meter of colligation once.
Burying underground of self-rebound force balance loading case also needs to meet " pile body self-rebound force balance Static Test Technique code " (DB36/J002-2006).
?load box must be through having the provincial calibrating unit calibrating of calibrating qualification, and obtain qualified calibration certificate and can use.
Load box should adopt certain safeguard measure in loading, unloading and transportation, forbids rash-and-rough way of loading and unloading, does not allow extruding, sharp impacts, in order to avoid make casing, oil pipe and displacement bar joint impaired, impact is used.
?load box is being reached the spot, and as do not installed at that time, should be placed on from job site compared with distant positions or on-the-spot material keeping place, in order to avoid accessories such as other construction damage load boxes and oil pipes.
Oil pipe need guarantee to bear the required rated pressure of detection.
