Abstract
A kind of easy coarse granule porosity measurement technique is to squeeze into cylindrical steel drum in coarse granule ground to be measured so that it is determined that the volume of coarse-grained soil to be measured, then by the coarse-grained soil of excavation be contained in in cylindrical steel drum diameter identical open containers, using measuring cup, into open containers, injected clear water determines water filling volume to there is water logging to go out coarse-grained soil surface, and porosity is determined according to the ratio between water filling volume and the volume of coarse-grained soil.Beneficial effect is：Avoid tradition and determine that porosity causes the big technological deficiency of error by way of supposition；By using with graduated steel drum, the volume for injecting coarse-grained soil reclaimed water to be measured can accurately be measured by measuring cup with the volume of Accurate Determining coarse-grained soil to be measured, so as to realize that the high accuracy of coarse-grained soil porosity determines；The cylindrical steel drum and open containers of the present invention utilized Reusability and can be moved easily, and can effectively reduce measurement cost.
Description
Technical field
The present invention relates to building exploratory techniques field, more particularly to a kind of easy coarse granule ferroxyl test technique.
Background technology
In building construction process, through carrying out consolidation by grouting processing to ground frequently with slurry injection technique, to ensure matter of constructing
Amount, is generally accurately calculated grouting amount in advance, and the accurate calculating of grouting amount is it should be understood that the porosity of ground to be onstructed,
Porosity is all temporarily to calculate at this stage, no straightway testing method, so as to cause the grouting amount of ground certain deviation to be present, is influenceed
Structure safety.
Therefore, it is necessary to it is a kind of can Accurate Determining coarse granule porosity method so that ground can be by accurate consolidation by grouting.
The content of the invention
The present invention in view of the shortcomings of the prior art, proposes a kind of easy coarse granule porosity measurement technique, this method
Using coarse granule porosity can accurately be measured, and the determination for base grouting amount provides effective guarantee.
A kind of easy coarse granule porosity measurement technique：
Step 1：Smooth processing coarse granule ground to be measured；
Step 2：To be squeezed into graduated cylindrical steel drum in coarse granule ground to be measured, it is determined that cylindrical steel drum squeeze into it is to be measured
The volume of coarse-grained soil to be measured in coarse granule ground depth and cylindrical steel drum；
Step 3：The coarse-grained soil in cylindrical steel drum is excavated, and the coarse-grained soil of excavation is contained in straight with cylindrical steel drum
In the identical open containers of footpath, and described coarse-grained soil in the height of coarse-grained soil and cylindrical steel drum is contained in open containers
Height it is identical；
Step 4：Using measuring cup into open containers injected clear water to there is water logging to go out coarse-grained soil surface；
Step 5：The volume of the injection total clear water of open containers and the porosity that coarse-grained soil volume ratio is coarse-grained soil.
Further, the inwall of the cylindrical steel drum and outer wall are provided with graduated scale.
Further, it is provided with graduated scale on the inwall of the open containers.
Further, the cylindrical steel drum can also be square steel drum or cuboid steel drum.
The beneficial effect of technical scheme of the present invention is：On the one hand avoid tradition and hole is determined by way of supposition
Gap rate causes the big technological deficiency of error；On the other hand, using technical scheme of the present invention, by with graduated steel drum,
The volume for injecting coarse-grained soil reclaimed water to be measured can accurately be measured by measuring cup with the volume of Accurate Determining coarse-grained soil to be measured, from
And realize the high accuracy determination of coarse-grained soil porosity；Technical scheme of the present invention has operation easily, convenient and practical, cost
The characteristics of relatively low, in addition, the cylindrical steel drum and open containers of the present invention utilized Reusability and can be moved easily, energy
Effectively reduce measurement cost.
Embodiment
In order that those skilled in the art more fully understand technical scheme, with reference to specific embodiment to this
Invention is described in further detail.
Using technical scheme of the present invention before, it is necessary to smooth processing be carried out to coarse granule ground to be measured, then by
The graduated circular hollow steel drum of outer wall is squeezed into coarse granule ground to be measured, manually by the coarse-grained soil in circular hollow steel drum
Excavate totally, excavate the depth that coarse granule ground to be measured is deeply squeezed into for the hollow steel drum of circular hole of coarse-grained soil.
The coarse granule to be measured excavated is contained in in cylindrical steel drum diameter identical open containers, and described being contained in
The height of coarse-grained soil is identical with the height of coarse-grained soil in cylindrical steel drum in open containers；It is thick so as to reduce same depth
The volume of granular soil and overall porosity situation.
Using measuring cup, into open containers, for injected clear water to there is water logging to go out coarse-grained soil surface, record is injected into opening this moment
Clear water total amount in container.
The volume of the injection total clear water of open containers and the porosity that coarse-grained soil volume ratio is coarse-grained soil.
To hold the volume of coarse-grained soil in accurate determination open containers, scale is provided with the inwall of the open containers
Chi.
During using technical scheme of the present invention, the cylindrical steel drum can also be square steel drum or cuboid steel
Bucket.
Using technical scheme of the present invention, on the one hand avoid tradition and determine that porosity causes to miss by way of supposition
The big technological deficiency of difference；On the other hand, using technical scheme of the present invention, by with graduated steel drum, can accurately survey
The volume of fixed coarse-grained soil to be measured, the volume for injecting coarse-grained soil reclaimed water to be measured is accurately measured by measuring cup, so as to realize thick
The high accuracy determination of grain soil pores rate；Technical scheme of the present invention has operation easily, convenient and practical, lower-cost spy
Point, in addition, the cylindrical steel drum and open containers of the present invention utilized Reusability and can be moved easily, can effectively it drop
Low measurement cost.
A kind of easy coarse granule porosity measurement technique provided by the present invention is described in detail above, herein
In apply embodiment the principle and embodiment of the application be set forth, the explanation of above example is only intended to help
Understand the present processes and its core concept；Meanwhile for those of ordinary skill in the art, according to the thought of the application,
There will be changes in specific embodiments and applications, in summary, this specification content should not be construed as to this
The limitation of application.
