Abstract
The invention discloses a measuring device for differential settlement of pile-soil, which comprises a first settlement mark and a second settlement mark, wherein the first settlement mark is arranged on an engineering pile cushion cap; the second settlement mark is arranged on soil between piles; the first settlement mark comprises a baseplate; a vertical upright is fixedly arranged on the baseplate; horizontal suspension arms are arranged at the upper end of the vertical upright; the structure of the second settlement mark is the same as that of the first settlement mark; and the first settlement mark is arranged relative to the second settlement mark. Through the structural design, the measuring device has the advantages of capability of measuring the distance between the two suspension arms directly by means of a vernier caliper and conveniently measuring the differential settlement of the pile-soil quickly, strong operability, good repeatability, and higher precision.
Description
Technical field
The present invention relates to the foundation settlement field of measuring technique, relate in particular to a kind of device that in position the native relative settlement of stake is carried out high-acruracy survey.
Background technology
The analysis and the control of the native relative settlement of stake are the important contents of pile foundation engineering always.In the prior art, the common equipment of the native relative settlement of monitoring stake is settlement plate or sedimentation mark post, settlement plate or sedimentation mark post is measured to obtain the data of the native sedimentation of stake by level gauge at the different time node.Wherein, horizontal survey especially will be carried out repeatedly measurement of the level, not only waste time and energy, inefficiency, and poor operability, and also the survey data that obtains is also accurate inadequately.
Therefore, those skilled in the art is devoted to develop the measurement mechanism of the native relative settlement of a kind of efficient, high-precision stake.
Summary of the invention
Because the above-mentioned defective of prior art, technical problem to be solved by this invention provides the measurement mechanism of the native relative settlement of a kind of efficient, high-precision stake.
For realizing above-mentioned purpose, the invention provides the measurement mechanism of a kind of native relative settlement, comprise first sedimentation mark that is arranged on the engineering piles cushion cap and be arranged on second sedimentation mark on the inter-pile soil; Said first sedimentation mark comprises and is set with vertical rod on the said substrate by substrate that the upper end of said vertical rod is provided with the cantilever of horizontal arrangement; Said second sedimentation mark is identical with said first sedimentation mark structure, is provided with in opposite directions.
Preferably, said substrate is square iron plate.
Preferably, said vertical rod is connected and composed through bolt by plurality of sections of steel pipes.
Preferably, said cantilever is a reinforcing bar.
Preferably, said cantilever is weldingly fixed on the said column.
The invention has the beneficial effects as follows:
The measurement mechanism of the native relative settlement of stake of the present invention is measured the relative settlement of stake soil quickly and easily because the said structure design can directly be measured two spacings between the cantilever by slide measure, and is workable, good reproducibility, and precision is higher.
Below will combine accompanying drawing that the technique effect of design of the present invention, concrete structure and generation is described further, to understand the object of the invention, characteristic and effect fully.
Description of drawings
Fig. 1 is the structural representation of the measurement mechanism of the native relative settlement of stake of the present invention.
The specific embodiment
As shown in Figure 1, measurement mechanism one specific embodiment of the native relative settlement of stake of the present invention comprises first sedimentation mark that is arranged on the engineering piles cushion cap 1 and is arranged on second sedimentation mark on the inter-pile soil 2.
Particularly, first sedimentation mark comprises that the upper end that is set with first vertical rod, 42, the first vertical rods 42 on first substrate, 41, the first substrates 41 is provided with first cantilever 43 of horizontal arrangement.First substrate 41 is a square plate, is processed by the iron plate of length of side 400mm.
First vertical rod 42 is connected and composed through bolt by plurality of sections of steel pipes, optionally the free adjustment height.
Second sedimentation mark is identical with first sedimentation mark structure, comprises that the upper end that is set with second vertical rod, 32, the second vertical rods 32 on second substrate, 31, the second substrates 31 is provided with second cantilever 33 of horizontal arrangement.
Second sedimentation mark is provided with first sedimentation mark in opposite directions, and especially, second cantilever 33 and first cantilever, 43 keeping parallelisms are good.
The method of operating of the measurement mechanism of the native relative settlement of stake of the present invention is following:
At first, first sedimentation mark, second sedimentation mark are set respectively on engineering piles cushion cap 1, inter-pile soil 2.
, wait banket completion after, on schedule at interval, utilize slide measure directly survey read spacing first cantilever 33 and second cantilever 43 between, can obtain relative settlement numerical value at following soil of load action thereafter.
The present invention can directly obtain the relative settlement numerical value of stake soil directly by the spacing between two cantilevers of vernier caliper measurement, and is convenient, fast, workable, good reproducibility, and precision is higher.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can design according to the present invention make many modifications and variation.Therefore, all technician in the art all should be in the determined protection domain by claims under this invention's idea on the basis of existing technology through the available technical scheme of logical analysis, reasoning, or a limited experiment.
