Abstract
The utility model relates to a mechanical drilling filling pile and belongs to the technical field of burying of a loading box of the mechanical drilling filling pile. The mechanical drilling filling pile comprises the loading box, wherein an upper reinforcement cage and a lower reinforcement cage are respectively connected with the upper end and the lower end of the loading box, a guide rib is welded between the upper reinforcement cage and the loading box, a reinforcement cage outer stirrup is arranged on the outer edges of the upper reinforcement cage and the lower reinforcement cage, and an annular plate is arranged at the lower end of the lower reinforcement cage. The annular plate is additionally welded at the bottom end of the lower reinforcement cage, so that the reinforcement cage and the loading box are kept in the center of a pile hole to the greatest extent when buried, and the overlarge data deviation of two lower displacement rods is not caused in the follow-up detection process.
Description
Technical field
The utility model relates to a kind of machine drilling castinplace pile, belongs 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, all can there be the tapering being caused by engineering machinery drill bit bottom.Yet, 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 purpose of this utility model is to provide a kind of machine drilling castinplace pile.
To achieve these goals, the utility model adopts following technical scheme:
A 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, in the lower end of described hypomere reinforcing cage, is provided with annular slab.
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.
The beneficial effects of the utility model:
1, data accuracy improves:
Hypomere reinforcing cage bottom is welded with annular slab, can make reinforcing cage and load box when 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:
Without carrying out special training, get final product left-hand seat, only the main muscle in hypomere reinforcing cage bottom need be welded on annular slab, diameter must equal outer stirrup diameter, with load box, connect and be positioned in stake 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 guarantee because bury reinforcing cage and load box underground, tilts excessively, and load box, in applying 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the installation site schematic diagram of the auxiliary muscle in the right angle in the utility model (6).
The specific embodiment
Below in conjunction with 1,2 pairs of the utility model of accompanying drawing, be described in detail:
A 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;
In described epimere reinforcing cage 2 and the outer rim of hypomere reinforcing cage 3, be provided with stirrup 5 outside reinforcing cage, in the lower end of described hypomere reinforcing cage 3, be provided with annular slab 7.
Epimere reinforcing cage 2 is provided with the auxiliary muscle 6 in right angle with the junction of load box 1.Preventing that reinforcing cage and load box are thrown off in burying process underground drops.
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 during 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 be used 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 guarantee concordant.
While placing self-rebound force balance loading case in pile foundation, 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 rules > > (DB36/J002-2006).
?load box must be examined and determine through having the provincial calibrating unit of calibrating qualification, and obtains 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.
