Abstract
Provided is a device for detecting the bearing capacity of a piercing annular foundation pile. More than two circular ring bodies form an annular oil cylinder body through bolt connection and seal rings, the annular oil cylinder body is connected with a hydraulic station through an oil pipe, the middle of the annular oil cylinder body is a cylindrical hollow cavity, an upper displacement rod is welded on the upper wall of the annular oil cylinder body and sleeved by an upper sheath pipe, and a lower displacement rod is welded on a welding plate of a lower plate and sleeved by a lower sheath pipe. The device for detecting the bearing capacity of the piercing annular foundation pile can meet the tonnage requirements of various foundation piles and quick and convenient to use and process, detection tonnages to be achieved of the foundation piles are ensured only according to different loading pressures, numerous complicated procedures are decreased, and the device can be manufactured to be a serialized standard detection device according to the appearance size requirement of the foundation pile. If the detection tonnages are required to be increased in the using process, the requirement can be achieved by manually controlling and changing pressure supplied by the hydraulic station, and therefore the detection flexibility of the foundation pile is greatly improved.
Description
Technical field
The utility model relates to the punching circular base pile capacity checkout gear of measuring foundation pile supporting capacity in a kind of building foundation pile driving construction.
Background technology
The construction of construction-engineering project, particularly highrise building, large-scale structure, need to be used a large amount of pile foundations.Requirement according to country about ground and pile foundation engineering inspection of quality standard, reply foundation pile test pile and engineering pile carry out the detection of bearing capacity static load, to determine and to check its bearing capacity of single pile, as the mandatory term of pile quality acceptance requirement.The counterforce device of the static loading test ballast platform that tradition is initial is by sand pocket and concrete precast block counterweight on ballast platform; Stacking sand pocket and concrete precast block be very heavy, feel unwell complete, consume a large amount of sand pockets, speed is slow, efficiency of construction is low, it is low to transport efficiency.
Summary of the invention
The purpose of this utility model is just to provide that a kind of operating efficiency is high, flexibility good, the punching circular base pile capacity checkout gear of applied range.
Punching circular base pile capacity checkout gear of the present utility model, by plural torus, be bolted and sealing ring looping cylinder body, annular cylinder body is connected with Hydraulic Station by oil pipe, the middle part of annular cylinder body is cylindricality cavity, top offset bar is welded on the upper wall of annular cylinder body and is nested with upper jacket pipe, bottom offset bar is welded in the welding plate of lower plate, is nested with lower jacket pipe on bottom offset bar.
Punching circular base pile capacity checkout gear of the present utility model, during use, at the bottom of annular cylinder body is placed in foundation pile stake or foundation pile stage casing, the upper wall of annular cylinder body and epimere foundation pile reinforcing cage are welded as a whole, the reinforcing cage of the lower plate of annular cylinder body and hypomere foundation pile is welded as a whole, and top offset bar, bottom offset bar are by the straight-through earth's surface of upper and lower protecting pipe.Hydraulic oil enters in annular cylinder body by oil pipe, and annular cylinder body opens, and the upper wall of annular cylinder body and lower plate produce upper and lower displacement amount, and reflect by top offset bar and bottom offset bar.
Punching circular base pile capacity checkout gear of the present utility model, can meet multiple foundation pile requirement tonnage, only need guarantee the detection tonnage that foundation pile will be realized according to on-load pressure difference, this structure is convenient, fast in using and processing, a lot of numerous and diverse formalities have been reduced, and can be according to the requirement of foundation pile appearance and size, make the standard detection device of seriation, it in use increases and detects tonnage as needed, Artificial Control changes Hydraulic Station supply pressure and can realize, and has so just greatly improved the flexibility that foundation pile detects.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
A kind of punching circular base pile capacity checkout gear, by plural torus, be bolted and sealing ring looping cylinder body 9, annular cylinder body 9 is connected with Hydraulic Station by oil pipe 10, the middle part of annular cylinder body 9 is cylindricality cavity 4, top offset bar 2 is welded on the upper wall 1 of annular cylinder body 9 and is nested with upper jacket pipe 3, bottom offset bar 5 is welded in the welding plate 7 of annular cylinder body lower plate 8, is nested with lower jacket pipe 6 on bottom offset bar 7.
During concrete perfusion, grout pipe is extended through to the cylindricality cavity 4 of annular cylinder body 9, be conducive to like this bottom sediment better to roll up, guarantee accuracy, safety that whole pile detects.
In testing process, hydraulic oil is injected to annular cylinder body 9, arrive after certain thrust, whether checkout gear starts to open and form the displacement of upper and lower foundation pile, finally according to the displacement of foundation pile, come judgement basis pile bearing capacity qualified.If this stake is test pile, can be according to the feature of punching circular base pile capacity checkout gear in testing process, increase again thrust and make it to destruction, so can measure the ultimate bearing capacity of test pile easily, thereby can be better for design provides test basis.
Complete after loading, allow checkout gear release, no longer head on foundation pile, make its foundation pile can free resilience to record and comprise foundation pile springback capacity in interior foundation pile precise displacement amount, thereby greatly improve the measuring accuracy to foundation pile displacement.
