Description
Technical field
The present invention relates to a kind of building operations and detect machinery, particularly relate to the testing equipment in construction work pile foundation construction, foundation pile being carried out to quiet loading test.
Background technology
Pile foundation is a kind of base form being widely used in construction work.Pile foundation is as the important component part of main structure body, its quality good or not is directly related to the overall security of building, and the multifactorial differences such as geological conditions, construction technology, execution control level and pile foundation raw material all can have influence on pile quality and single pile bearing capacity; In order to ensure pile foundation engineering quality, all need detection or the sampling Detection of pile foundation engineering being carried out to single pile bearing capacity in Practical Project, its test item mainly comprises single pile vertical resistance pressure dead-load detection and unit for single-pile vertical anti-pulling dead-load detection.
The detection experiment of current pile foundation supporting capacity mostly adopts ballasting platform counterforce device (accumulation load method).Its ballasting platform counterforce device is a bearing platform be made up of main girder steel and time girder steel, and the heavy thing of the heap that pile is some on this bearing platform, piles heavy thing and usually adopt precast concrete balancing weight, or sand bag, water tank, brick and cast steel block etc.When building-site detects, first be built into bearing platform with girder, secondary beam, again the counterweights such as precast concrete one piece of block is deposited on bearing platform, therefore in this detection experiment, also special must be equipped with a special purpose crane, be used for handling primary and secondary beam and precast concrete counterweight etc.; The ballasting platform counterforce device put up must be pulled down again when detecting another foundation pile, be transported to another foundation pile place and again build bearing platform, transport also lifts counterweight again, when tested foundation pile is apart from each other, also need the supporting transhipment of haulage vehicle, which again increases the handling operation on haulage vehicle.Therefore existing pressure platform counterforce device, need during operation haulage vehicle and crane etc. the tracking of Special Equipment coordinate, what need constantly to carry out platform builds the handling again with counterweight again, consumes a large amount of manpower and materials, it is large that material transport builds repeated workload, not only experimentation cost is high, and detection time is long, and operating efficiency is low, and labour intensity is large, in transhipment handling and pile process, there is more safe weak spot, easily cause security incident, safety factor is low.Existing pressure platform counterforce device is that loose mail scene is spliced simultaneously, and globality is not strong, and be also easy to lost in transhipment, add the working time and work difficulty of again building, the detection of existing foundation pile affects progress and the efficiency of engineering construction significantly.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of engineering foundation pile static load stride detection platform, and it can not only carry out overall transfer of freely walking, and builds without the need to what repeat and lifts, and rational in infrastructure, use safety, and operating efficiency is high.
In order to solve the problems of the technologies described above, engineering foundation pile static load stride detection platform of the present invention, comprises bearing platform, and described bearing platform is supported on two long ships and two short ships movably; These two short ships lay respectively at the two ends of bearing platform; Each short ship is provided with moveable short shipping agency mule carriage, short shipping agency mule carriage is fixedly connected with short ship revolving dial, and the vertical lifting hydraulic cylinder be installed on bearing platform is hinged mutually with short ship support platform; This short ship revolving dial is hinged by revolution bearing pin and short ship support platform; Described two long ships lay respectively at the both sides of bearing platform; Each long ship is provided with two moveable long shipping agency mule carriages, long shipping agency mule carriage is hinged in the lower end of long ship supporting leg corresponding with it, and this long ship supporting leg is installed on bearing platform by long ship supporting leg crossbeam; Be provided with long shipping agency between long shipping agency mule carriage and long ship and walk hydraulic cylinder; Bearing platform is provided with crane.
After adopting said structure, because bearing platform is supported on long ship and short ship movably, thus enable detection platform by the interleaved ground of long ship and short ship and liftoff, realize the front and back of bearing platform, move left and right, and gyration, testing inspection platform is had and freely walks and pivotal function, not only length travel can be realized, lateral displacement, and can gyration be realized, mobile flexible, completely avoid the complicated work repeating to set for this platform and repeat to lift counterweight of the prior art, operating efficiency improves greatly, usage safety performance is also ensured.Again due to long ship and or be provided with vertical lifting hydraulic cylinder between short ship and bearing platform, lifting or depression can be realized by vertical lifting hydraulic cylinder bearing platform, when carrying out single pile vertical resistance pressure dead-load detection, vertical lifting hydraulic cylinder lifts pile holding load carrying platform and executing and overweighting on foundation pile of counterweight, carries out the detection of Compressive Bearing Capacity; And when carrying out unit for single-pile vertical anti-pulling dead-load detection, vertical lifting hydraulic cylinder imposes a upper force pulling upwards by bearing platform to foundation pile again, to carry out the detection of anti-pulling capacity; There is the effect of one-machine-multi-function.Also owing to being equipped with crane on carrying platform, the lifting of counterweight can be carried out voluntarily, without the need to the cooperation of other crane during operation, operating cost is low, operating efficiency improves, not by the restriction of external condition.Be connected with short ship support platform by relative hinged short ship revolving dial with vertical lifting hydraulic cylinder in the mule carriage of structure of the present invention short-and-medium shipping agency, by this double-decker realize detection platform traversing and revolution; Be provided with long shipping agency between long shipping agency mule carriage and long ship and walk hydraulic cylinder, and long ship supporting leg does not use vertical lifting hydraulic cylinder, avoid the platform sinking that pressure release causes, measure inaccurate phenomenon, this is simple and reasonable, can conveniently realize and the vertically moving of detection platform.
The present invention is a preferred embodiment again, and described bearing platform adopts the cabinet board structure adding intrinsic deep floor on the downside of platform panel.Bearing platform adopts overall structure, convenient transfer, Stability Analysis of Structures, can carry more ballast, adopts long and short ship structure to have the advantages such as conveniently moving, operation high efficient and flexible, contact area specific pressure are little, is suitable for Various Complex working condition.This Stability Analysis of Structures, weight capacity are stronger, good integrity.
