Abstract
The utility model relates to a self-reaction force balance load box testing platform. A square hollow cavity is arranged in the middle of a vertical plate. Two to six vertical plates with the same shape and size in equal-distance arrangement are fastened, positioned and connected through horizontal connecting columns which are arranged between the vertical plates. The lower ends of all the vertical plates are fastened, positioned and connected with a base. A top plate, a bearing plate and a bottom plate of which the horizontal planes are the same penetrate through the square hollow cavities of the vertical plates. The top of the top plate is fastened, positioned and connected with the upper part of the vertical plate, and the bottom of the bottom plate is fastened, positioned and connected with the lower part of the vertical plate. Pressure sensors and oil return cylinders are symmetrically and uniformly distributed on the upper plane of the bottom plate. The bearing plate is arranged on the pressure sensor. The pressure sensor is connected with a computer and a display by conducting wires. The utility model can detect the loading capability of the pile hydraulic load box, the stability of continuous force loading, the internal and external leakage of the hydraulic system, and the like, and ensures the reliability of the pile hydraulic load box when carrying out hydraulic loading on the pile.
Description
Technical field
The utility model relates to a kind of testing equipment, particularly a kind of test table of self-counter force balance loading box.
Background technology
The construction of construction-engineering project, particularly highrise building, large-scale structure needs to use a large amount of pile foundations.According to the requirement of country about ground and pile foundation engineering inspection of quality standard, reply foundation pile test pile and engineering piles are carried out the bearing capacity static load and are detected, to determine and to check its bearing capacity of single pile, as the mandatory term of pile quality acceptance requirement.Traditional detection method is to use the sand pocket counterweight on the ballast platform, stack sand pocket very heavy, feel unwell complete, consume a large amount of sand pockets, speed is slow, efficiency of construction is low; The current pile foundation hydraulic pressure load case that adopts carries out hydraulic loaded to pile foundation more, detects bearing capacity of pile foundation.Need a kind of pile foundation hydraulic pressure load case testboard, in order to detect the actual loaded ability of pile foundation hydraulic pressure load case for this reason.
Summary of the invention
The purpose of this utility model has provided a kind of test table of self-counter force balance loading box that detects pile foundation hydraulic pressure load case load capability.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of test table of self-counter force balance loading box, vertically the middle part of riser is provided with the square cavity, block-shaped and measure-alike, mutual top and the bottom that equidistantly is arranged in parallel and has the vertical riser of same cavity axis of 2-6, by fastening being located by connecting of horizontal joint pin between them, whole vertically lower ends of risers and pedestal is fastening is located by connecting; The horizontal plane size of the top board that all is horizontal, bearing plate and base plate equates that the width of top board, bearing plate and base plate is less than the square cavity width of vertical riser, and top board, bearing plate and base plate penetrate the square cavity of vertical riser; Be located by connecting with vertically riser top is fastening by last angle support arm above the top board, base plate is located by connecting with vertically the riser bottom is fastening below by the inferior horn support arm; Uniform setting pressure sensor of plane symmetry and symmetrical uniform installation oil return oil cylinder are laid bearing plate on described pressure sensor on base plate, and pressure sensor is connected with described computer and display lead; The oil return oil cylinder shrinks when putting in place, and the top of oil return oil cylinder does not contact with the bearing plate lower plane.Distance on the described bearing plate between plane and the top board lower plane is greater than tested pile foundation hydraulic pressure load case height, and vertically the square cavity width of riser is greater than tested pile foundation hydraulic pressure load case width.
The beneficial effects of the utility model are: it can detect pile foundation hydraulic pressure load case load capability, the stability that continues loading force and the performances such as internal and outernal leakage of hydraulic system, quality inspection when being used for pile foundation hydraulic pressure load case and dispatching from the factory, drop into before the engineering construction or the Performance Detection after the maintenance, guarantee pile foundation hydraulic pressure load case when pile foundation is carried out hydraulic loaded reliability and the quality of engineering construction.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Embodiment is shown in Fig. 1-2: a kind of test table of self-counter force balance loading box, the middle part of its vertical riser 1 is provided with the square cavity, four block-shaped and measure-alike, mutual top and the bottoms that equidistantly are arranged in parallel and have the vertical riser 1 of same cavity axis, by 2 fastening being located by connecting of the horizontal joint pin between them, the lower end and pedestal 10 fastening being located by connecting of all vertical riser 1.The horizontal plane size of the top board 4 that all is horizontal, bearing plate 5 and base plate 8 equates that the width of top board 4, bearing plate 5 and base plate 8 is less than the square cavity width of vertical riser 1, and top board 4, bearing plate 5 and base plate 8 penetrate the square cavity of vertical riser 1; By last angle support arm 3 and fastening being located by connecting in vertical riser 1 top, base plate 8 is below by inferior horn support arm 9 and fastening being located by connecting in vertical riser 1 bottom above the top board 4.Plane on base plate 8, be symmetrical in the vertical line at base plate center, six pressure sensors 6 of uniform installation and four oil return oil cylinders 7 of uniform installation are laid bearing plate 5 on described pressure sensor 6, pressure sensor 6 is connected with described computer and display 11 leads; Oil return oil cylinder 7 shrinks when putting in place, and the top of oil return oil cylinder 7 does not contact with bearing plate 5 lower planes.Distance on the described bearing plate 5 between plane and top board 4 lower planes is greater than tested pile foundation hydraulic pressure load case 12 height, and vertically the square cavity width of riser 1 is greater than tested pile foundation hydraulic pressure load case 12 width.
During test, tested pile foundation hydraulic pressure load case 12 is placed on the central authorities of bearing plate 5, starts the load cylinder of pile foundation hydraulic pressure load case 12; Withstand top board 4 above the pile foundation hydraulic pressure load case 12, push down bearing plate 5 below, and will pass to pressure sensor 6 up to the pressure of 50000KN.Pressure sensor 6 outputs signal to computer and display 11, storage, demonstration or printing test data.After test finishes, because the load cylinder of single pass pile foundation hydraulic pressure load case does not have external force can not shrink discharge hydraulic oil voluntarily; Must start oil return oil cylinder 7,, help the load cylinder of pile foundation hydraulic pressure load case to shrink oil return bearing plate 5 and the pile foundation hydraulic pressure load case roof pressure that makes progress.Subsequently, oil return oil cylinder 7 shrinks decline again, just extensible tested pile foundation hydraulic pressure load case 12.
