Their life is not easy, ask everyone is different, their positions differ, do not have the desire to understand and agree with everything. Hard little sad thing something big, say those who may not be true, the listener need not suspicious, if someone really think that hurts you, it is really finished. Live their own happiness, live your own understanding. Cement concrete sleeper pillow is also called, also known as concrete pillow. Made of concrete, steel, combination, looks hard and long life to you first explain the classification of cement sleeper bar; cement sleeper sleeper installation can be divided according to U-ring and pressure plate bolts concrete sleepers U-ring Easy installation, just put the rails between the two U-rings, rubber mat beneath the pad, and then spending a U-shaped ring with a sledgehammer to suppress the rail. Cement sleepers plate bolts are reserved by T-bolts from below the hole piercing the top sleeper hold the plate to suppress the rail, a sleeper need four sets of bolts, four clips, two rubber pads, this sleeper convenient conservation can be reused. Advantages cement cement sleeper sleepers require steam stripping a shape, the appearance of smooth, hard inside, and contains a plurality of rebar. Cement timber source extensive pillow, the same size, elasticity uniformity, good insulation, high stability, unaffected by weather conditions to outside temperature, does not rot and long service life. Prestressed concrete sleepers can save a lot of high-quality steel in addition, there are long life, good stability track to meet the high-speed, large capacity requirements and so on. Sleeper track structure is an important component to withstand a variety of forces from the rail, and the flexibility to spread the force on the track bed, while effectively maintaining gauge, direction and location of the track. The main advantage of concrete sleepers are: vertical, large transverse resistance, provide sufficient stability to meet the requirements of the railway; sleeper carrying capacity can be designed according to different operating conditions to meet durability requirements for long term use. Concrete sleepers are mainly raw materials of cement, aggregates, steel, water and the amount of additives, such as admixture. Sleeper standard sebang strength in mining of raw materials made requests. (1) cement, aggregates, steel intensity level to meet the design requirements. (2) cement and aggregates are proposed to meet the base, the active ingredient content requirements. (3) for coarse aggregate gradation, fineness modulus and cleanliness fines set forth requirements. State of the World Mining concrete sleepers extremely strict quality requirements, into the form of inspection and testing sleeper factory inspection. In addition to the appearance of quality in the form of test items sleeper existing line, the various dimensions and the strength indicators, reporting an increase of raw materials, the alkali content of the assessment of coagulation, elastic modulus of concrete, chloride ion permeability of concrete, pre-processing or iron casing seat pullout, lichen and rail fastening assembly insulation resistance. Factory inspection and an increase of elastic modulus of concrete projects. Product quality and performance meet the requirements shall not be shipped.

After a long practice shows concrete sleepers and rail accessories to meet the needs of the railway, and has a long service life, maintenance workload is small. Buy concrete sleepers to the State of the World, the World State sleepers a good process. 1, automatic batching and mixing process control required to achieve accurate fit than feed mixing, sebang mining features with automatic weighing, batching, mixing control device functions well can automatically record timely, query and modify each step of the process parameters. 2, reinforced Zhang Yi leveled prestressing steel, stirrups and spiral ribs must separately meet the requirements of technical conditions. Prestressed steel tensioning process procedures prepared in advance, the total tensile force in strict compliance with the design drawing. 3, the pouring of concrete and vibrated concrete sleeper technology cementitious material amount does not exceed 500kg / m3, which is to not generate excessive heat of hydration. The density of concrete sleepers have a significant impact on the life, so we have different fabrics, perfusion, vibration equipment and process planning for different production processes. Ensure the density of concrete sleepers to achieve the best value. 4, steam curing technology for health sleeper when using steam at a temperature of not more than 3 0 C environment quiet stop for no less than 3 h; concrete heating rate of not more than 1 5 ℃ / h; there is a certain time to stop the steam cooling, cooling speed of not more than clever ℃ / h; at the end of the health sleeper surface and pit work and outdoor temperature of not more than 15 ℃. After stripping sleeper, wet health than 7 days; when the ambient temperature is below the winter SC, sprayed concrete and cover to keep warm moisturizing regimen agent layer. As one of the important components sleeper track structure, its own structure must be optimized. Such as fasteners and sleeper coupling must be reliable, its orbit under the cushion must have sufficient flexibility to play a role in reducing vibration and noise, and the elastic cushion elasticity and elastic strips must also have a good match. Some problems in the quality of the concrete sleeper factory Management are: quality management awareness is weak, extended use of common steel, resulting in wire position allowed; management system is not strict, in order to cope with the static load rupture strength test, take over Zhang pull even increase non-normal reinforcement measures directly affect the life of the sleeper; tooling equipment management in place, poor equipment condition is difficult to guarantee the quality sleeper; the raw material inspection there are still large gaps, including cement, aggregates, additives, water lack of raw materials and other strict inspection; automation, low intelligence, the production process is subject to factors such as greater impact. Sleeper in strict accordance with the conditions of transport and line-level use; maintenance and repair to be performed in accordance with sleeper tamping force characteristics to avoid discontinuity reasonable damage sleeper, sleeper construction must guard against rough handling and construction equipment to be complete.
