Study the simple and easy laboratory report in China's steel geology

This experiment regards hitting the steel stratum as the datum, do the simple and easy experiment of imitating, such as Fig. 1

Imitate the proportion of soil layer as follows:
One layer of proportions of moisture sand: Water invites about 2500 gs of fine sand of 2000CC
The proportion of soil layer: ? About 1500 gs of soil
Imitate the stove stone in the railway and go through the proportions: The stone and gravel of the stove are a grain of about 500 gs
Imitate one layer of proportions of broken stone in the railway: Broken stone is about 1500 gs
Put the ground graticule mesh above the soil layer in accordance with the level, such as Fig. two

Fig. left weave cotton cloth the place graticule mesh for made in Britain plastics, the Fig. makes rubber ground graticule mesh for serious hundred million in right, put the stone and gravel of the stove after one above, such as Fig. three

Block with plank in case broken stone squirt on lying in putting, after the two person who shake
Person who shake after opening one one minute, made in Great Britain ground soil layer of graticule mesh already have mud that has emerged and looked like
The shaking device rotates / divides for 1300

The already complete mud of the graticule mesh is welled up for British system after the shaking device opens 10 minutes , in weight hundred million make ground graticule mesh, a bit little
Mud it lasts elephant to be the getting getting more more apparent.

This experiment time is ten minutes,
After digging and starting the broken stone in both sides and stove stone gravel one after finishing, find both sides have phenomenon that broken stone sag, but in weight hundred million make broken stone, ground of graticule mesh sag comparatively on average

Is it develop now to dig downwards, British system doses of on net stove stone gravel grains of a wet watching nearly slightly one is it have moisture .

Serious hundred million make ground doses of on net stove stone gravel grain, find out that there is moisture but relatively find out the moisture, .

After taking out the ground graticule mesh on both sides, is it is it find to turn on to dig soil layer of both sides,
The graticule mesh obviously has stoves a phenomenon of falling into downwards of stone and gravel for British system, deepen the soil layer and well up on sand layer slightly .

And in weight hundred million make ground a dose of soil layer surface off the net some little stove stone gravel one put into downwards only, the sand is welled up on layer not apparent,

Compare two border district graticule mesh find, British system to weave cotton cloth stove stone gravel one that pay graticule mesh, among the fibre that deepening does not weave cotton cloth, weave cotton cloth relatively easy to break too ,

And in weight hundred million make ground graticule mesh because rubbery, rubber flexible and flexible strength, so the stove stone gravel one is unable to deepen, the water is lost once washing

Summarize: The graticule mesh of ground made in Great Britain, does not weave cotton cloth and work out and relatively have no pulling force by the fibre, it is easy to be deepen by the stove stone gravel one,
It is relatively apt to be scratched by the broken stone too, cause mud well up sand layer well up and stove stone gravel grain sink, let whole ground put into and send to the inequality phenomenon of road surface downwards.
And in weight hundred million make ground graticule mesh, abolish rubber make, the rubber flexible and pulling force, difficult to be deepened by the stove stone gravel one, difficult to be passed through many hands or places broken by the broken stone, the silt emerges like being comparatively difficult on layer, so will not cause the ground to sink either, and the inequality phenomenon of road surface.
Supplement: British system graticule mesh is it it pigeonholes to be 102 to shoulder, in weight hundred million make ground graticule mesh is it it pigeonholes to be 468 to shoulder

Experiment two
In the same way, put the graticule mesh of two places above the soil layer, one for have ground graticule mesh of pore, graticule mesh put the following picture after finishing for have pore,

Fig. left for have place graticule mesh of pore, Fig. for have place graticule mesh of pore right, up, put on stove stone gravel grain and broken stone grain put the following picture after finishing in two ground dose,

It is blocked in order to prevent breaking to pieces with the plank on the broken stone that again ten is squirted, put two shaking devices separately on the plank,
After opening about 2 minutes, it have by sand already both sides not emerging the on the layers like,picture

Dig both sides soil layer to develop it now five minutes later, there are no place graticule meshes of the pore, the soil layer has not levelled the form, but there are place graticule meshes of the pore, the soil layer comparatively levels the following picture

And then cut the soil layer on both sides after being poured, find that there are not place graticule meshes of the pore, the soil layer has obvious level changes,
And there are place graticule meshes of the pore, the soil layer is comparatively levelled, the following picture
Summarize: Have place graticule mesh of pore, because surplus moisture unable to is it cause sand layer well up and pursue layers of not smooth high or low prices to appear, causing the road surface to be not smooth to some extent, there are place graticule meshes of the pore, because there are pores the surplus moisture can be appeared from the pore,
So sand layer and soil layer can protect fair and whole, have more difficult to have sink and level unequal phenomenon road surfaces.

Supplement: Experiment this graticule mesh is it it pigeonholes to be 468 to shoulder with it have pore, have place graticule mesh of pore is it it pigeonholes to be 702 to shoulder.

Experiment three
Regard hitting the steel ground as the datum and do the further experiment, the following
This proportion of soil layer is as follows:
Whether absorb water the proportion of the sponge. Water invite 3500c.c and big sponge first
One layer of proportions of moisture sand: The moisture invites 3500c.c, about 4000 gs of fine sand
The proportion of soil layer: The universe soil is about 3000 gs
Imitate the proportions of stone and gravel of the railway stove: The stone and gravel of the stove are a grain of about 2000 gs
Imitate one layer of proportions of broken stone in the railway: Broken stone is about 3000 gs
Put one place graticule mesh to have pore above soil layer, stove stone gravel each put one place the following icon of graticule mesh to have pore

Soil layer not whole and it is the back without being finished since whether graticule mesh put, put two department shaking devices on the plank, the following picture
After vibration opens two minutes and 40 seconds, it emerge on being the getting less a bit sand layer and soil layer like,icon

Shake after opening one minute, sand layer and soil layer well up comparatively obvious, has not it invade broken stone layer upwards to have, the following icon

And then dig the plank and broken stone to open, find the place graticule mesh of one layer of ground remains the universe, the following icon

Is it turn on to dig stove stone gravel grain downwards, emerge as but fairly intact in soil layer, the following icon on moisture have

And then pour and cut the whole soil layer and find, sand layer and structure in the soil layer, still calculate and level and not relatively have sand that emerge alikely,
The following icon

Summarize: There are place graticule meshes of the pore in two stories, because there are pores can let the surplus moisture be discharged, can let mud layer and sand layer well up or let stove stone gravel grain not to sink, would not lead to the fact the ground to sink too, phenomenon of or the ground of unequal height.

Supplement: Experiment this is it it pigeonholes to be 468 to shoulder with it place graticule mesh

Experiment four:
This experiment regards hitting steel geology as the datum, carry on the simple and easy experiment of imitating.

The proportion of whole soil layer:
One layer of proportions of moisture sand: Water invites 3000C.C, about 3000 gs of fine sand
The proportion of soil layer: The universe soil is about 3000 gs
The universe sand one layer of proportions: Fine sand of the universe is about 200 gs
Imitate the proportions of stone and gravel of the railway stove: The stone and gravel of the stove are a grain of about 500 gs
Imitate one layer of proportions of broken stone in the railway: Broken stone is a grain of about 1500 gs
Put the ground graticule mesh above the universe sand floor in accordance with the level, the following picture

Go to Fig. left for in weight hundred million person who make rubber graticule mesh, go to Fig. Right deviation a graticule mesh of place made in Britain.
And then putting, stove stone gravel one and broken stone one, the plank and shaking device.
The following picture after finishing

After the shaking device opens 5 minutes, find emerge alikely on British system there is the soil layer of the graticule mesh,
And hundred million soil layer which make the ground graticule mesh is comparatively intact again.

And then dig and open the broken stone and stove stone gravel one, person who find British system dose on the net for little moisture, picture the following

And in weight hundred million make ground graticule mesh only some little moisture too, picture the following
And then take out the place graticule mesh, pour and cut the whole soil layer, find the soil layer of the graticule mesh of ground made in Great Britain, some little sand falls into
It is relatively unequal too that the soil layer divides the line, serious hundred million make ground graticule mesh have sand fall into relatively, soil layer divide into line to be comparatively intact even. The following picture

Conclusion:
There is one layer of sand more above the soil layer in this experiment, because there is a layer of sand on the soil layer, and it is difficult to appear to cause the moisture of lower floor,
Weave cotton cloth easy to is it cause underground surplus moisture once gush out to gall broken stone, and then cause the whole ground to sink, and the rubber itself draws setting up and elasticity, difficult to be galled by the broken stone, the underground surplus moisture will just be appeared slowly when reaching certain strength of atmospheric pressure of ground

Experiment five:
Water experiment that completely and appearing the thick consistency comparison of the moisture, the experiment method is made the dose on net of ground in British system graticule mesh and heavy hundred million, put the fine sand, height is about 0.5 centimeters, the following two pictures

Great Britain makes ground graticule mesh, because does not weave cotton cloth, so need to pat and exert pressure with hands while dripping, could let the mud and water droplet leave,
Mud water comparatively thick and thick, and in weight hundred million make rubber ground graticule mesh, because it have it is will slowly in water in mud in so hole in a utensil drip downwards,mud the getting more rare relatively in water, the following two pictures

Therefore can know, rubber graticule mesh is it filter function to have, plastics do not weave cotton cloth ground graticule mesh, need pressure ability ink completely, so has not filtered the function, and then cause the earth to flow out or gush out.

Experiment six:
Test the intensity of two kinds of ground graticule meshes, wear-resisting degree.
Put the broken stone in dose off the net of two kinds of ground in experiment method, then put the shaking device in the ground graticule mesh, the following two pictures
British system is already some little phenomena of breaking of graticule mesh after shaking for ten minutes, shake in weight hundred million after the ten minutes make ground graticule mesh have only original holes detailed still too, the following two pictures

Reason: Graticule mesh is it can break to weave cotton cloth made in Britainly, apt to cause mud well up or phenomenon that sand fall into, and then cause ground lower limit or inequality issue, and in weight hundred million make ground graticule mesh rubber system, unless it have it is broken for hole issue, not so does not can have caused mud not to be welled up or last issue sand,because make hundred million rubber not in weight hole detailed graticule mesh itself, can let the surplus moisture be appeared, will not let the silt run out of, so will not cause the lower limit of the ground or inequality question, in addition, rubber itself is it is it shake function to suck, can reduce vibrations issue, railway of load too to have, as to the thing that stratum last sinking and inequality problem,can effective improvement.
