Q:How do the rails of high-speed railways dock?
Solve the thermal stress of thermal expansion and contraction by the following ways:1, perfect temperature monitoring equipment.2, the manufacturing process to reduce thermal expansion and cold contraction effect. When laying, should also choose the appropriate temperature, so that the minimum value of expansion.3, the tracks are locked on the sleepers so that their stresses are forced to lock. In regions with large temperature differences, regular discharge stresses should also be applied. It is said that the sudden release of the construction site stress, momentum is amazing!
Q:What is rail thermit welding?
Thermit welding is a kind of thermit welding, and it is the most common welding of rails. Aluminium heat welding between the parts to be welded to set aside a certain gap around the mold wall, then ignited in the crucible of flux through a redox reaction, exothermic formation of liquid metal, the liquid metal into the gap between welding pieces, metal welding.Thermit welding process are: rail end preparation - sand mold preparation, pre heating and welding package preparation - casting, sand mold and push the tumor to remove grinding.
Q:Why is there a gap between each rail on the railway?
The rail must provide a continuous, smooth, and least resistant rolling surface for the wheel. In electrified railway or automatic block section, rail can also be used as track circuit.
Q:Several questions about high speed rail and subgrade.
You said in front of the concrete board has already said is the track board, the following "cushion" should refer to the CA mortar filling layer, that is, cement, asphalt, mortar layer. The main function is to support the track plate, to buffer the load and shock absorption of the high speed train. The main materials are: cement, emulsified asphalt, fine aggregate, water and a variety of additives. The edge breakage has no direct effect on its performance, but in the long run there must be some adverse effects, especially the ageing resistance.
Q:Why is the railroad track free of expansion joints now?
Buy high iron, steel reinforced insulation insulation card _ tie rail (cross word type), hot melt gasket (can also be used for vegetables piperoof construction), SK--2 type rail protection cover, telescopic tube, screw cap protective cover.
Q:High speed rail runs so many trains a day, what about rail wear?
The track is regularly checked and repaired. These are upstairs, in addition, the EMU because the car is light, but also the whole car power, the rail wear is not large, there is no heavy haul trains. What's more, its curves and downhill slopes have been computed without any large downhill or small radius curves. Secondly, high-speed rail or rail lines or, in addition to rail bottom slope on rail surface will advance and regular grinding, in order to form a point of view, the train is running, but can improve the wheel through smoothly.
Q:What are the characteristics of a curved track compared with a straight one?
Rail function:Take the wheel load directly and transfer it to the sleeper, guide the wheel of the train; provide the least resistance surface for the wheel roll.In electrified railway or automatic block section, rail has the function of track circuit.Requirements for rails:Sufficient strength, stiffness and surface should have good smoothness and wear resistance. When the wheel passes, the rail will not deform too much, so as to reduce the dynamic impact between wheel and rail.Rail type: expressed by the mass kilogram per meter. The main types of rail in China are 75, 60, 50, 43, four types, and their quality per meter is 74.414, 60.64, 51.514, and 44.653kg, respectively. Rail 60 is widely adopted in the speed increasing main line and the high-speed railway. 75Rail is used on heavy haul lines.
Q:Is the rail of the railway made of steel? Or iron or iron?
Rail is a forging, steel and iron are essentially different from the amount of carbon content. The carbon content of steel is 0. 0218%-2. Between 11%, the carbon content of the cast iron is 2. 11%-6. 69%.Such as a rail model is: 60U71MN, the rail belongs to manganese steel 60, indicating that the weight is 60KG/mU71 means 0.71% carbon content
Q:Why are some city railways called light rail? What is heavy rail?
Heavy rail is larger than light rail cross section and can bear more force. The early line railway, as well as the use of 38 kg of rail, now is the use of 50 kg and 60 kg."Subway", "light rail" do not confuseRail transit to adopt medium passenger volume, can adapt to the long-term one-way maximum peak hour, passenger flow 1.5 - 30 thousand passengers become light rail. If the large passenger carrying two cars, can adapt to the long-term one-way peak hour, passenger volume of 3 - 60 thousand passengers collectively referred to as the subway.
Q:What is the connection mode of the return cable on the rail?
Current transformer installation should pay attention to several points: one is the two circuit transformer is not allowed to open, to prevent the generation of high voltage induction harm, two is the two circuit grounding point, three is the current level of transformer should be greater than or equal to the maximum current in the main circuit, otherwise will exceed the current table
