Description
Technical field
The utility model relates to a kind of displacement measuring device for self-balanced test method, belongs to foundation pile technical field of measurement and test.
Background technology
Self balanced method technology, its Cleaning Principle is by a kind of special charger-load box, imbedded corresponding position in stake (particular location is determined according to the different object of test) together with steel reinforcement cage before concreting, the proving installations such as the forcing pipe of loading case and required displacement are guided to ground from pile body, then pours into pile.Loaded to load box pressurization on ground by force (forcing) pump, load box produces the power of upper and lower both direction, and is delivered to pile body.Because pile body and the ground side resistance of stake week have counter-force of one's own, will the data being equivalent to two static tests be obtained: load box with upper part, the respective reaction parameters in series of upper part pile body when we obtain Opposite side loading; Load box is with lower part, we obtain the respective reaction parameter of lower part pile body when forward loads. by the computation and analysis to relation between loading force and these parameters (displacement etc.), not only bearing capacity of pile foundation can be obtained, when after the pre-buried certain stress of pile body, strain testing element, a series of pile foundation engineering design data such as ultimate frictional resistance parameter, ultimate end resistance of pile of every layer of Rock And Soil can also be obtained.This principle test pile is called self-balanced test method by domestic industry, and this method may be used for, for pile body design provides data foundation, also can be used for the inspection of engineering pile bearing capacity.Application number is: " 200920086024.8 ", denomination of invention is: the Chinese patent literature of " a kind of displacement acquisition device for self-balanced test method " once disclosed a kind of displacement acquisition device for self-balanced test method, this device is connected with spring clip device wire rope one end, then to enter under spring clip device in pillar and along its inwall slide downward, when arriving load box position, on the top board that just can be stuck in load box or on base plate, there is weight in wire rope other end system simultaneously, ensure that wire rope is in exceptionally straight state, wire rope is around on the rope sheave of grating sensor, when wire rope moves up and down, just corresponding grating sensor key light grid can be driven to do clockwise or rotate counterclockwise, realize the conversion of straight-line displacement to angular displacement.But, the suspension fixed head of this device is fixed on crossbeam, grating sensor is arranged on and hangs on fixed head, wire rope is around on the rope sheave of grating sensor, in actual test process, because the diameter of tested test pile differs, and the position hanging fixed head can not regulate, wire rope often cannot vertically around the rope sheave of grating sensor after drawing in pillar, this not only also exists operating difficulties, uses very inconvenient problem, and the measuring accuracy of self-balanced test method pile displacement also can be affected when measuring, do not reach ideal effect.Therefore, the result of use of the displacement measuring device of existing self-balanced test method or not ideal enough, can not meet the needs of use.
Utility model content
The purpose of this utility model is, provides a kind of displacement measuring device for self-balanced test method, and this apparatus structure is simple, flexible operation is changeable, and the pile body that can adapt to different-diameter is measured, and measuring accuracy is accurate, to overcome prior art deficiency.
The technical solution of the utility model: a kind of displacement measuring device for self-balanced test method, comprise in self-balanced test method the displacement silk connecting load box top or bottom, the supporting leg of more than at least three is provided with in the surrounding of supporting seat, supporting leg is sliding combined with fixed pulley assembly, displacement filament winding is connected with mass after crossing the fixed pulley on fixed pulley assembly, is fixed on the amount of movement of the displacement transducer Real-Time Monitoring displacement silk on supporting leg.
Between adjacent supporting leg, hang with crossbeam by suspender, crossbeam is sliding combined with fixed pulley assembly.
The first sleeve that aforesaid fixed pulley assembly comprises fixed pulley and is slidably matched with supporting leg or crossbeam, is provided with lock-screw in the first sleeve both sides.
Aforesaid suspender comprises the second sleeve be slidably matched with supporting leg and the 3rd sleeve be slidably matched with crossbeam, and the 3rd described sleeve also can rotate around hanging to sell with the second sleeve connection by hanging pin, and the second sleeve both sides are provided with lock-screw.
Aforesaid displacement silk adopts carbon-dioxide arc welding silk to make, and carbon-dioxide arc welding silk plasticity_resistant deformation ability is comparatively strong, and its ductility can be ignored, and guarantees the measuring accuracy of displacement.
Owing to adopting technique scheme, the utility model is connected with mass after displacement filament winding being crossed the fixed pulley on fixed pulley assembly, ensure that displacement silk is in tensioned state all the time, the position of this fixed pulley assembly can free adjustment in the horizontal plane simultaneously, make displacement silk and horizontal plane, ensure that the measuring accuracy of self-balanced test method pile displacement is more accurate.Therefore, not only structure is simple for the utility model, flexible operation is changeable, can adapt to the measurement of the pile body displacement of different-diameter, and measuring accuracy is accurate, significant to the popularization of self-balanced test method.
