Technical solution adopted in the utility model is: a kind of device detecting the barrel-shaped foundation anti-pulling bearing capacity of suction, and it is made up of frame construction, assembly pulley, casing, ground, suction bucket and balance weight body; Described frame construction is formed by bolt link by two vertical slots shaped steel and a horizontal square bar; Described assembly pulley is made up of a movable pulley and two fixed pulleys, is linked together by steel strand; Described casing is the hollow cuboid that top is opened wide, and is formed by Plate Welding; Described ground is divided into two-layer, and upper strata is seawater, and lower floor is sand, is filled in casing; Described suction bucket is bottom-open, and the hollow steel rounding pillar buoy of air-vent is left at top; Described balance weight body forms by loading bucket, loading bucket retaining wall and counterweight.
Construction usage method of the present utility model is: first welded steel strand fixed point by the design attitude on the square bar of designing requirement in frame construction, install two fixed pulleys, again the vertical slots shaped steel of two in frame construction and a horizontal square bar are built by bolt link, and carried out supporting in base position by a pole pair frame construction; Then immediately below steel strand fixed point, casing is laid, first the sand in ground is filled in casing, then adds seawater, until reach design height, adopt hydraulic jack suction bucket pressure to be passed through in the sand entered in ground, the top of suction bucket and the absolute altitude of sand are flushed; Then steel strand are fixed on the steel strand fixed point in frame construction on square bar, successively movable pulley is connected with two fixed pulleys, the end of steel strand is fixed to and loads on bucket, is connected by the threading post at suction bucket top with movable pulley by steel strand, and loading bucket retaining wall is installed; Finally, experimentally requirement, places counterweight, at the uniform velocity loads in loading bucket, when the top of suction bucket has just exceeded seawater absolute altitude, stop loading, and record has loaded the counterbalance mass loaded altogether in bucket, calculates the anti-pulling capacity of suction barrel base.
Operating principle of the present utility model is: a kind of device detecting the barrel-shaped foundation anti-pulling bearing capacity of suction, makes the power of loading be reduced to the half of loading force needed for direct method by the use of movable pulley, make loading more laborsaving.Meanwhile, the use of two fixed pulleys changes the direction of direct method loading force, makes operation more simple, is easy to grasp.After once experiment terminates, all plant and instrument are all reusable, and easy installation and removal is simple to operate, thus reach the effect of high efficiente callback utilization.
The beneficial effects of the utility model are: a kind of device detecting the barrel-shaped foundation anti-pulling bearing capacity of suction, not only can change the loading direction of power, and make loading more laborsaving, after the function services phase terminates, the all plant and instrument of this device is all reusable, reaches the object recycling, economize on resources.This device not only efficiently solves a detection difficult problem for the barrel-shaped foundation anti-pulling bearing capacity of ocean engineering suction, and structure simple, mount and dismount easy, Technological Economy is feasible.
