The elongated series winding bolt 6 consistent with the road junction width adopted at each road junction, and middle fixation clip 3 can adopt multistage to install as required.
One, the performance of the outer slab of slab and rail in the rail:
1, mechanical property
Because the large-scale heavy duty vehicle will be passed through in the road junction, so higher to the mechanical property requirements of paved crosing.For mechanical properties such as the resistance to compression of strengthening the paving, anti-folding, shock resistances, just need to carry out reinforcement to material.According to the characteristics of material, adopting fibrous reinforcement is to select preferably.For making the paving reach best mechanical property, also adopted cage of reinforcement reinforcement way, mainly be that the GB indented bars carries out the reinforcement of double-layer cross intersection, the mechanical property of paved crosing is further strengthened, obtained very good effect.
Mechanical property test result:
Rupture strength: the 500KN(50 ton)
By heavily block drive form 8 * 4(namely 4 axles 12 take turns), 150 tons of calculating of load-carrying: each is taken turns and is capable of carrying a load of 12.5 tons.
Resin paved crosing width is 500mm, and tyre width is 315mm, and 1 tire can only pass through in every paving.
More than reach a conclusion: 50 tons 12.5 tons, paved crosing force request head and shoulders above.
2, electrical insulation capability
Paved crosing need to be laid on the part in the middle of two strands of rail, and will all fill, and has formed connection like this between two strands of rail, and laying in automatic and Semi-automatic Block District just needs the paved crosing insulating properties good.Surface electrical insulating properties and the volume electrical insulation capability of the utility model paved crosing reach+∞.
3, wear-resisting, fire-retardant, corrosion-resistant, anti-aging, non-skid property
(1) increase the unsaturated bond in the polyester molecule chain and increase crosslinking points in the resin, make its thermosetting after rigidity increase, abrasion resistance improves.
(2) anti-flammability mainly relies in the resin in the content of halogen compound, or adopt add antimony oxide, phosphate improves fire resistance greatly.
(3) by increasing crosslink density, improve crystallinity, improve the resin chemical resistance, make it structurally more closely knit.Adopt bisphenol-A and oxirane or expoxy propane compound and propane diols or ethylene glycol to unite use, better improve its corrosion-resistant, ageing resistace.
(4) on structure design, the anti-skidding special design that carried out of effects on surface, surface distributed 5cm(is long) * 5cm(is wide) * 5mm(is high) protruding non-slipping block, every block gap 20mm.
4, low-shrinkage
Product size is accurate, outward appearance is good in order to make, and prevents underbead crack and hole, makes the whole mechanics of product reach optimum state, needs the shrinkage factor of strict control product.Add chemicals the shrinkage factor of mylar is controlled in 3%, just can be controlled at 0.1%-0.2% to the physical dimension of product, and the product zero defect.
5, the simplification of the globality after the product mix and assembling and disassembling
Paved crosing long perfomance life and convenience easy to maintenance, very important concerning permanent way maintenance department.If the paved crosing globality is bad, play, activity just cause paved crosing to damage easily, reduce application life, and monomer volume and weight that this just needs to strengthen paved crosing strengthen globality.But strengthen monomer volume and the weight of paved crosing, make again maintenance work become very difficult, be difficult for installing and removing.In order to solve the contradiction of this respect, the utility model is considered from size, weight, the structure design of paved crosing, is reached the purpose that 2 people can finish maintenance activity.Then, consider from the paving spare and accessory parts again, carrying out integral body with the series winding bolt laterally connects, utilize jig and rail, sleeper integral reinforcing, so both accomplished that the globality after the product mix was strong, prolong the application life of paved crosing, accomplished again the simple and convenient of assembling and disassembling, greatly alleviated maintenance load.This resin road junction pavement structure is reasonable, installs simply, and is easy to maintenance, can save maintenance man-hours more than 60%.
6, the key technical indexes
(1). rupture strength: 500kN
(2). compressive strength: 195MPa
(3). electrical impedance :+∞
(4). abrasion resistance: 3.10mg/cm
2
(5). application life: 6-8
7, comparison in equipment of the same trade
This paved crosing has that intensity height, resistance to compression and fracture resistance are good, indeformable, anti-aging, corrosion-resistant, service life long, the attractive in appearance eye-catching advantage such as colour-fast.And cost is low, it is very convenient to install, dismantle, and saves a large amount of manpower and materials, reaches leading domestic level.
Two, the calculating of Social benefit and economic benefit and analysis
1, social benefit analysis
The characteristics that the resin paved crosing has is safe and reliable, volume is little, weight is moderate, various aspects of performance is excellent, cost is low, alleviated operating personnel's labour intensity and saved the activity duration.Replace other paved crosing can prolong the application life of paved crosing with it, save great amount of cost, be fit to be layed in all kinds road junction, especially be fit to be laid on the road junction of current heavy-duty vehicle.
In the last few years, fast development along with China's economy, heavy duty, the large-tonnage automobile is very universal, fast development for adapt to economic development, works department is also had higher requirement to the paved crosing structure, especially to the material of paved crosing, that structure is improved requirement is more urgent, the research and development of this kind paved crosing material, to improve the paved crosing structure, improve the road junction quality, prolong paving application life, alleviate maintenance load, the aspect effect such as increase economic efficiency is very outstanding.Promote and use the current development of the situation of resin paved crosing adaptation.
2, Economic and Efficiency Analysis and calculating
1), improved efficiency
Paved crosing according to 5 meters of paving width calculates, and lays single line one place's resin paved crosing, and 10 people needed just can finish in 1 hour.Paved crosing 10 people that lay other type needed just can finish in 2-3 hour, increased work efficiency nearly 3 times.
2), reduced maintenance cost
1. lay the paved crosing of 5 meters other types of width, 10 people finished 1 place in 3 hours, laid 1 hour 10 people of resin paved crosing and finished 1 place.Be calculated as follows: by 3000 yuan of operating personnel's monthly salary, 22 working days per month, activity duration every workday is to calculate in 8 hours:
Per hour personnel's cost of labor is 3000 ÷, 22 ÷ 8=17.05 units.
17.05 * 10 * 3-17.05 * 10 * 1=341 unit.
At least 34.1 ten thousand yuan of expensess of labour are just saved at the annual maintenance of the overall situation about 1000 Yu Chu road junctions, road junction.
2. extension device application life, save cost and drop into
6500 yuan/meter of rubber road junction costs, 6000 yuan/meter of resin paved crosing costs are saved 500 yuan for every meter.And aging distortion will occur in the rubber paved crosing about 2 years at busy, heavily loaded road junction, cause physical dimension not meet the regulation of " repairing rule ", must change, and the resin paved crosing can reach 6-8 application life, be the 3-4 in its application life doubly, calculate according to dropping into 1000 meters paved crosings, save about 1,350 ten thousand yuan of cost:
Lay the resin paving:
Ten thousand yuan of 6000 * 1000=600.
Lay the rubber paving:
6500 * 1000 * 3(is 3 times of rubber application life)=19,500,000 yuan
Save ten thousand yuan of cost: 1950-600=1350.
3), improved quality
Because the resin paved crosing has the characteristics such as intensity height, resistance to compression and fracture resistance are good, indeformable, anti-aging, corrosion-resistant, globality is strong, stopped the problem that paved crosing is broken, lose, be out of shape, wear out, the road junction equipment quality is greatly improved.
