Fill out the sea ground train wheel and shake and shoulder the mashed of keeping to fall into the principle
Describe: Steel offer Da Cheng help CSC study track geological drilling analysis report made narrate content feel and plan the experiment contrast at the problem of draining off water in consulting?
1. Steel fill out sea sand ground set up the track, its low stratum contains (from lower to upper) in consulting The stone and gravel of the stove are each. And mix layer and one to cut layer.
2. The ground? Dark result can receive way of factory cut thickness about 70 centimeters, getting yellowish-brown powder quality clay to 3.6 it is on powder quality to get into deep less than degree grey powder quality from clay to powder quality fine sand clay.
3. The material that the track wells up the mud should belong to the pale brown powder quality clay, it is distributed in order to invite 1m place under the earth's surface, the thickness invites 2.5m, but perhaps because the train wheel shakes the repeated influence back and forth, in order to pollute to the earth's surface 0.8m office upwards, is it gush out the situation in ground to have.
Conclusion:
1. It is about 70 centimeters to study and judge and cut the thickness in accordance with the way of the factory, getting yellowish-brown powder quality clay to 3.6 it, on powder quality to get into deep less than degree grey powder quality from clay to powder quality fine sand clay
1m。 Total and invite 1m.
2. What is meant by is it keep mud fall into structure layers of density receive, track load cause, train wheel load is it is it turn to cut to go to shoulder, wheel is it is it shake wave to produce, produce powder quality fine sand vortex form infiltrate, is it is it dissolve cement soil into to wash to well up to pigeonhole, is it is it is it suck loose to have stove stone gravel each and dish of density cut layer occupied welling up mud material getting pale brown powder quality clay to press to shoulder to produce.
3.It makes underground temperature rise that weather is hot, underground temperature is it is it is it rotate to cut to go by wheel load train to improve, wheel is it shake wave is it is it is it make groundwater swarm soil swarm with these groundwater too to keep to shoulder to produce to pigeonhole.

The complex rubber strains water graticule mesh
(Geosyntics) Worker's synthetic, generally (Geosyntics) Development to last half century,but the new
,The space that can develop is also suitable and big. Ground worker put more energy into graticule mesh is to use in use, earth of project put more energy into his material of graticule mesh while being so-called on fabrics among them synthetic, worker of ground; High density polyethylene (HDPE) The board, via casting and pressing mould shaping or polyester in advance (PET) The fibre is after weaving alternately; Wrap and cover the polyvinyl chloride (PVC) Or polypropylene (PP) The membrane is made. Putting more energy into the graticule mesh can divide into two big classes; One getting hard graticule mesh PP plastics, another kind of soft graticule mesh polyester (PET) The fibre covers the membrane, make strength in friction strength and anchor exposed to the soil, can construct and resist the strong shock result, it cooperate weave cotton cloth not straining water function,the own to it is put more energy into shelf the strong in soil, by putting more energy into put more energy into slope, soil layer not weak, mix road grade there aren't lower floor to widely used. Research institute first with transfer to tubes of type is it wrap up person who wind is it make PP/ PET make core yarn to spin to twist, utilize and then graticule mesh of putting more energy into worker fabric person who process is it it makes to be and then flat to organize graticule mesh and gauze organization graticule mesh, Engineer of place, worker of ground, to knit, study the contact brute force of two kinds of different tissues ground engineering graticule mesh fabric.,PVC、Include and soak other materials (for example, PVC, pitch, emulsion,etc.) And succeed.
1. (American Society of Testing and Materials)2.ISO (International Standards Organizatitute)3.GRl (Geosynthetics Research Institute) Second, hit now adopt Britain not to be imported this in railway project for steel the the steels Companies,last compounding type last material norm worker (last graticule mesh type not hard) First, the present situation adopts and imports PP material graticule mesh abroad, it compound it stick to hotly weave cotton cloth there aren't material PP. test ASTM for U.S.A. and material association (American Society of Testing and Materials) 2.ISO is ISO(International Standards Organization) (International Standards Organizatitute) 3.GRl formates the material research institute for the ground worker (Geosynthetics Research Institute) 2, construct and lack the compounding type engineering formate materials (hard type put more energy into the graticule mesh) ; 1. Is it purchase and is it delay railway project repair progress often to construct to import abroad. 2. It is a PP material that the hard type puts more energy into the graticule mesh, construction is difficult, transport and accumulate the large, whole ground smoothly, spread hard type put more energy into graticule mesh wave unsmooth arc, close garrulous stone, make ground to be unable to be steady and sure. 3. Compound hot to stick to PP weave cotton cloth material strain ink, very easy damage, because pave the hard type and put more energy into the unsmooth arc of wave of the graticule mesh, because cover the sharp edge of garrulous stone again, whole ground weave cotton cloth material broken hole when being smooth, leak mud is it make railway to be load sunken to flow out.
Third, isolate the function (including filtering with detention) The so-called segregation is with the ground worker's fabric ( Do not weave cotton cloth or weave cotton cloth) Detention ( Retention) With filtering ( Filtration) The gravel material that the function hinders the basic unit of dead end falls into the gradually weak ground floor because the repeated loading of the rut excites excess hole water pressure, prevent particulate material of ground floor from rise the pollution basic unit but reduce their bearing capacity with excess hole water pressure too. But worker fabric is it pigeonhole too low and unable to exhaust slowly to shoulder with fill out sea ground torpedo car rail. Drain off water some outside drain rainwater wash down, because graticule mesh and broken stone hard to use worker fabric broken hole naturally getting long just like sharp knife.
Company railway project, steel of China, this adopt Britain import now, engineering formates materials in the compounding type that called, the norm (hard type puts more energy into the graticule mesh) Compound hot to stick to PP weave cotton cloth material strain water easy damaged mud issue.

Whether fourth, by in weight hundred million industrial Limited Company for hit steel special project design, make production technology, to adopt. Compound rubber strain water graticule mesh, and on abolish rubber for tire to be hot to is it reduce regeneration make to take, put more energy into graticule mesh is it do on strain water sift, overlap integrative technology fill a prescription worker law to prop up, the mechanical wheel presses shaping. Is it abolish rounds of rubber is it able to bear thing and isolate load load to reduce, is it able to bear strong wear-resisting to is it enclose graticule mesh play person who contract to be good to decrease to take precautions against earthquakes to adopt, the simple and easy project of construction, compound the rubber strain water graticule mesh;
1. Purchase at home, construct railway project repair progress to be easy to control.
2. Play and compound rubbers hard and softly and strain water graticule mesh, the rubber material, construction simple and easy, is it accumulate light, whole smooth ground to transport, spread soft to compound rubber strain ink graticule mesh urgent ground, cover the garrulous stone steady and sure and smoothly.
3. Play and compound rubbers hard and softly and strain water graticule mesh, material prop up graticule mesh of doing and strain water cloth and abolish rounds of rubber reduce, whole wheel is it compound rubber strain ink graticule mesh jointly to pigeonhole, because do not cover the sharp edge of garrulous stone, the broken stone hook is broken, the graticule mesh rubber strains water to sift.
Fifth, conclusion: Steel become heavy to help CSC study track geological drilling analysis report made narrate at the problem of draining off water in consulting? Many number of times simulation experiment verify wheel is it shake wave and is it is it keep theory well up the mud thing to shoulder to produce to pigeonhole. In weight hundred million company study experiment personnel is it dispel track load and wheel that cause pigeonhole shock wave fasten to think together, can improve and well up the mud and material, because what there is no shock wave to fasten preaches to isolate, the structure of density of powder quality clay is not full of cracks and forming the clay, powder quality fine sand have swirl form wave fasten easy to infiltrate, is it is it shake wave is it can keep natural physical phenomenon know mud fall into to fasten to dispel to try one's best. Such eight items as filtering, draining off water, isolating, putting more energy into, detention, protection, elasticity, flexibility,etc. all reach. It enable exhausting to press high to shoulder, the ones that drained off water and changed fast but slowly exhaust, drained off water. Graticule mesh play hard having elasticity can cutting broken stone easily soft, needn't afraid small fine sand block worker grit damage well up mud, mud person who fall into factor inside the fabric in ground either. Compound rubber strain water graticule mesh is it use fabric, Engineer of place, to need, itself have and environmental protection rubber strain, reduce number of times of maintaining and lengthen the road surface or track service life.
In weight a hundred million Company study experiment personnel The first kind of complex rubber strains water graticule mesh (shoulder and press for 468) , second import PP material graticule mesh hot to is it weave cotton cloth to stick to abroad (is it press for 102 to shoulder) Shake the wave experiment to two major kinds of contrasts; Mud fall into, well up mud, drain off water, is it press, grit, is it shake, filter, not getting flexible and multiple to compare with experiment feel and plan the result newspaper to separate to shoulder; Please consult the experiment to compare with the report
