Abstract
The utility model discloses a pile foundation settlement detection ruler which comprises a ruler body, a high-precision dip angle sensor arranged on the ruler body, a rotary shaft located on one side of the ruler body, a simply-supported point located on the other side of the ruler body and a reference peg located on the lower portion of the rotary shaft. The pile foundation settlement detection ruler further comprises a gradienter installed on the ruler body, the simply-supported point can move left and right, and scales are arranged on the ruler body.
Description
Technical field
The utility model relates to a kind of pile foundation sedimentation detection gauge, relates in particular to a kind of pile foundation sedimentation detection gauge easy to use simple in structure.
Background technology
At present, the bearing capacity of pile foundation (containing ground) is to build one of most important parameter in Foundation Design design, construction, how to obtain by on-the-spot load test.In the on-the-spot load test of bearing capacity, need to measure the sedimentation of measured point under vertical load effect.For a long time, the measurement of sedimentation adopts traditional dial gage (mechanical type or numeral show) contact type measurement pattern always, must centered by measuring point, be symmetrical arranged two reference pegss, on two reference pegss, set up a datum line beam, dial gage is arranged on measuring point, realizes settlement measurement by the measuring staff contact datum line beam span centre of dial gage.
Wherein, reference pegs is witness mark, and datum line beam plays the effect of extending witness mark.Support, reference pegs and the datum line beam of dial gage, installation dial gage have formed settlement measurement system jointly.
This dial gage contact type measurement pattern is in order to meet the index of professional technique, requires the effective span of datum line beam to be at least greater than measuring point center and reference pegs centre distance 2 times.Conventionally, the span of datum line beam generally, between 5-12 rice, must keep enough rigidity, the firm or firm trussed construction of many employings type, and self is heavier.
In the time working long hours under the building site open-air atmosphere of the datum line beam of this long span, the Nonlinear perturbations such as deformation induced by gravity, temperature deformation of beam itself is serious, the survey data of obtaining in girder span, comprised the Nonlinear perturbations that the settling amount of pile foundation under trial load effect also comprised beam self, it is the mixed information after both superpose, destroyed the necessary stability of systematic survey, datum line beam is longer, self is heavier.Steady operation to measuring system is more unfavorable.This obvious deficiency that dial gage contact type measurement pattern exists, greatly reduces the measurement accuracy of system.
Therefore, be necessary to provide a kind of new technical scheme to overcome above-mentioned defect.
Summary of the invention
The purpose of this utility model is to provide a kind of measurement of dip angle pattern and working stability of adopting to use the pile foundation sedimentation detection gauge that simple accuracy is high.
For achieving the above object, the utility model adopts following technical scheme: a kind of pile foundation sedimentation detection gauge, it comprises blade, be installed on high-precision tilt angle sensor on blade, be positioned at described blade one side rotating shaft, be positioned at the freely-supported point of described blade opposite side and be positioned at the reference pegs of described rotating shaft below, described pile foundation sedimentation detection gauge also comprises the level gauge being installed on described blade, described freely-supported point can move left and right, and is provided with scale on described blade.
It is conical that described freely-supported point is.
Described high-precision tilt angle sensor can detect the inclination angle between described blade and horizontal plane.
It is parallel with described horizontal plane that described level gauge can demonstrate described blade upper surface.
Scale on described blade is taking described rotating shaft as starting point.
Compared with prior art, the utlity model has following beneficial effect: a kind of pile foundation sedimentation detection gauge of the utility model is simple in structure and convenient in use, described freely-supported point can regulate its position as required, expand the scope of application of pile foundation sedimentation detection gauge, improved the service efficiency of pile foundation sedimentation detection gauge.
Brief description of the drawings
fig. 1 is the structure chart of a kind of pile foundation sedimentation detection gauge of the utility model.
Detailed description of the invention
As shown in Figure 1, the utility model pile foundation settlement test chi comprise blade 1, be installed on high-precision tilt angle sensor 3 on described blade 1, be installed on level gauge 4 on described blade 1, be positioned at described blade 1 one sides freely-supported point 6, be positioned at the rotating shaft 2 of described blade 1 opposite side and be positioned at the reference pegs 8 below described rotating shaft.Described rotating shaft 2 contacts with described reference pegs 8 upper surfaces.Described blade 1 can rotate up and down around described rotating shaft 2.Described blade 1 is provided with scale, and taking described rotating shaft 2 as starting point.Described freely-supported point 6 can move left and right on described blade 1, and can read according to the scale on described blade 1 distance of described freely-supported point 6 and described rotating shaft 2.Described high-precision tilt angle sensor 3 can directly show the inclination angle a of its measured described blade 1 and horizontal plane.Whether the upper surface that described level gauge 4 can detect described blade 1 coincides with horizontal plane.Described freely-supported point 6 is turbination, and its drift angle contacts with the stake top subsidence survey point 5 of described stake 7.
When use, reference pegs 8 is arranged to the suitable position of pile foundation 7 one sides, now, freely-supported point 6 relies on the stake top subsidence survey point 5 of described pile foundation 7.The height that regulates reference pegs 8, makes level gauge 4 show that described blade 1 upper surface parallels with horizontal plane.Regulate the position of freely-supported point 6, read the described freely-supported point 6 of demonstration on described blade 1 and the distance l of described rotating shaft 2.In the time that stake top subsidence survey point 5 moves down, described high-precision tilt angle sensor 3 detects the micro-angle of described blade 1 and changes a.Then a measuring according to high-precision tilt angle sensor 3 and utilize trigonometric function just can calculate the Vertical Settlement amount of measuring point apart from l.
