Description

A kind of ground settlement instrument

Technical field

The utility model relates to settlement measurement technical field, in particular to a kind of ground settlement instrument.

Background technique

Ground settlement measurement is the major criterion for determining soil base load-bearing capacity and later maintenance difficulty.It is building It needs to carry out land survey before construction, and is also required to carry out regularly ground settlement measurement after construction, to protect The stability and safety that card building uses.

The ground settlement measurement method of the prior art jacks up clump weight 9 as shown in figure 8, first passing through jack 1.Then Support column 11 is placed in the two sides of clump weight 9, and sets up horizontal ruler 10 on support column 11, horizontal ruler 10 is located at jack 1 Lower section.Then it is fixed for measuring the dial gauge 6 of displacement in the two sides of jack 1.Height by adjusting support column 11 will After horizontal ruler 10 levels, the thimble of mobile dial gauge 6 is located at the upper surface of horizontal ruler 10.It is read according to different time of measuring points It takes the dial gauge 6 of different time nodes to read, to measure the degree of the sedimentation of clump weight 9, obtains ground settlement using conversion The case where.

It is that need to install jack installs horizontal ruler later again, then pacifies dial gauge in place of the deficiencies in the prior art Loaded on jack, complicated in operating process, instrument component is various, leads to the time for extending installation process.

Utility model content

The purpose of the utility model is to provide a kind of ground settlement instrument, and measuring scale is arranged on jack, then pass through hundred The distance for dividing table measurement measuring scale sedimentation, directly obtains the sedimentation situation of jack when clump weight acts on jack, reaches Facilitate the effect of construction.

The above-mentioned technical purpose of the utility model has the technical scheme that

A kind of ground settlement instrument, including jack, the jack are equipped with measuring scale, and the measuring scale is along the vertical direction It is rotationally connected on jack；The fixation group of measuring scale position after being used to lock rotation is equipped between the measuring scale and jack Part；The side of the jack is equipped with measurement column, and the measurement column corresponds to one end on measuring scale far from the jack and is arranged； Dial gauge is fixed on the measurement column, the thimble of the dial gauge is pushed against in the measuring scale upper surface.

By adopting the above technical scheme, in use, first being jacked up clump weight with jack, then rotation measuring ruler, to be measured Pass through the relative position between fixation kit fixation measuring ruler and jack when ruler relative level.Then measurement column is placed in survey Near position of the gage far from one end of jack, so that the thimble of dial gauge is pushed against in the upper surface of measuring scale.Work as jack When settling under the action of clump weight, the synchronous sedimentation of measuring scale, so that thimble moves down, the numerical value of dial gauge variation is heavy Drop amount, measurement with it is easy for installation, improve construction efficiency.

Further preferably are as follows: the fixation kit includes the fixed plate being fixed on the jack, and the fixed plate is in It is vertically arranged；The mounting groove of perforation setting, circumferential direction setting of the mounting groove along the fixed plate are offered in the fixed plate； The measuring scale is equipped with the adjusting bolt being threadedly engaged with it；The adjusting bolt is arranged across the mounting groove, and along institute The direction that opens up for stating mounting groove is slidably matched；When the relative position of the measuring scale and jack is fixed, the adjusting bolt One end push against in the fixed plate.

By adopting the above technical scheme, when the relatively large soil of measurement settling amount, such as soft soil foundation passes through mobile read Bar makes it be close to the upper surface of measuring scale or lower surface record initial value, then in the mobile survey of timing node for needing to record Gage reads the later period numerical value after sedimentation, and the difference of the two is settling amount, facilitates the reading of data, reduces measurement error.

Further preferably are as follows: the reading slot of perforation setting is offered on the reading wand, the reading slot is parallel to scale Line setting.

By adopting the above technical scheme, gauger reads data by reading slot, further facilitates reading, improves the standard of reading True property.

Further preferably are as follows: one end of the reading wand is equipped with fixing bolt, when reading wand is solid on the measurement column Periodically, one end of the fixing bolt is pushed against on the measurement column.

By adopting the above technical scheme, fixing bolt is inverted, so that the latch-release between reading wand and measurement column, is then moved Dynamic reading wand rotates forward fixing bolt, makes when measuring scale lower surface or upper surface are close in reading wand upper surface or lower surface The relative position for obtaining reading wand is fixed, and is then read the data of reading wand, is then unscrewed fixing bolt.

Further preferably are as follows: the dial gauge is fixed on the measurement column by adjusting component；The adjusting component packet Include the fixed frame being sheathed on outside the measurement column；The first bolt, first bolt and fixation are equipped on the fixed frame Frame is threadedly engaged；When dial gauge is fixed on measurement column, one end of the first bolt is pushed against on measurement column.

By adopting the above technical scheme, the distance between dial gauge and measuring scale are adjusted by moving up and down fixed frame.When It needs directly by the graduation mark on measurement column come when measuring settling amount, upward sliding fixed frame disengages it from measurement column, it is convenient The progress of measurement.

Further preferably are as follows: the measuring scale includes the first blade and the second blade, first blade and the second blade On be provided with level(l)ing bubble；First blade and the second blade are rotatably assorted, and first blade and the second blade it Between be equipped with for lock rotate after the first blade and the second blade relative position locking mechanism.

By adopting the above technical scheme, when the length of measuring scale is longer, the positional distance jack that measurement column is put is remoter, Soil layer i.e. below measurement column is influenced smaller by jack.Measuring scale is arranged to the shape that the first blade and the second blade merge Formula, one can lengthen the length of measuring scale, secondly facilitating the transport of jack and measuring scale.

Further preferably are as follows: the locking mechanism includes the fixed block being fixed on the first blade and is rotationally connected with described Connecting plate on second blade；The fixed block is threadedly engaged by threaded rod and first blade；On the connecting plate certainly Edge inwardly offers cooperation notch, and the cooperation notch and the threaded rod are mating；When first blade and second When blade is relatively fixed, the fixed block is pushed against on the connecting plate.

By adopting the above technical scheme, when needing to fix the position of the first blade and the second blade, the second blade of rotation makes It is coaxial with the first blade, is then rotatablely connected plate, so that cooperation notch and threaded rod matching, then rotate fixed block and make it It pushes against on connecting plate.

Further preferably are as follows: be provided with level(l)ing bubble on the measuring scale.

By adopting the above technical scheme, reduce dial gauge thimble it is mobile when the opposite sliding between measuring scale, further Improve the precision of measurement.

In conclusion the utility model has the following beneficial effects:

1, by the way that measuring scale to be fixed on jack, the case where jack settles directly is measured, has reached raising measurement The effect of efficiency；

2, by why dial gauge being arranged on measurement column, and graduation mark and reading wand are set on measurement column, so that soil is heavy The adjustment that drop instrument can require to measure according to different construction sites.
