A method for manufacturing an assembled railway crossing slab sleeper

Abstract

The invention discloses an assembled pillow for an integral cross plate of a rail and a manufacturing method thereof. The assembled pillow comprises high-strength steel slag concrete and high-strength synthetic resin concrete. Each cubic meter of the high-strength steel slag concrete comprises the following raw materials by weight: 8 to 70 of steel slag, 6 to 15 of cement, 2 to 3 of zeolite powder, 1 to 5 of mineral powder, 3 to 10 of a high-molecular polymerizer, 1 to 2 of organic acid, 2 to 3 of surfactant and 4 to 6 of a liquid additive. Each cubic meter of the high-strength synthetic resin concrete comprises the following raw materials by weight: 8 to 25 of synthetic resin, 5 to 20 of glass fiber, 10 to 50 of sandstone, 6 to 10 of silica fume, 2 to 9 of a hardener and 1 to 5 of an accelerator. The invention also discloses the manufacturing method. According to the assembled pillow for the integral cross plate of the rail and the manufacturing method thereof, the assembled pillow is employed, and high-strength steel slag concrete blocks and high-strength synthetic resin concrete blocks are manufactured and cooperatively installed; after laying of the concrete blocks, adjustment can be carried out through slip-casting, and an individual block can be dismounted and replaced; the assembled pillow is applicable to straight and curve sections and poses small influence to rail and road transport.

Description

technical field [0001] The invention relates to a method for manufacturing a crossing slab sleeper, in particular to a manufacturing method for an assembled railway integral crossing slab sleeper, which belongs to the technical field of infrastructure processing. Background technique [0002] Railway crossings and railway level passages are the passages for vehicles to pass the railway. They exist in large numbers in railway branch lines and railway freight yards. They have always been a weak link in the safety management of railway equipment. At present, the sleepers and pavements of railway crossings and railway level passages are mostly separated Laying form, the sleepers are ordinary reinforced concrete sleepers or wooden sleepers, and the crossing pavement mainly includes wooden sleeper row, steel rail row, concrete pavement panel and rubber pavement panel, etc.; with the rapid development of economic construction, the phenomenon of large vehicle traffic and large overlo...

Problems solved by technology

[0002] Railway crossings and railway level passages are the passages for vehicles to pass the railway. They exist in large numbers in railway branch lines and railway freight yards. They have always been a weak link in the safety management of railway equipment. At present, the sleepers and pavements of railway crossings and railway level passages are mostly separated Laying form, the sleepers are ordinary reinforced concrete sleepers or wooden sleepers, and the crossing pavement mainly includes wooden sleeper row, steel rail row, concrete pavement panel and rubber pavement panel, etc.; with the rapid development of economic construction, the phenomenon of large vehicle traffic and large overload is becoming more and more Intensified, resulting in various hazards at railway crossings, such as broken sleepers and difficult to find, rapid broken concrete pavement, rubber paved slabs tilted, rail rails connected to electricity or broken and tilted, seriously threatening the safety of the railway and the people passing the crossing The safety of people's life and property; at the same time, the drainage of the track bed and foundation bed under most crossings is not smooth, causing muddying disease, which greatly affects the operation of railways and highways

[0003] The overall crossing paving panel, after trial paving at some crossings, found that there are many serious defects. (1) During laying, the blockade of railways and highways was too long and the interference was large, so many crossings could not be laid. It is used at the crossings of individual special lines where the traffic volume of trains and cars is very small; (2) Once laid, it cannot be repaired. After laying, if the pavement is uneven, it cannot be adjusted, resulting in uneven rail surface. If a single pavement is damaged, It cannot be replaced separately. If a single rail fastener is tightened, the entire crossing filling rubber strip must be replaced; (3) The construction process is complicated, and the laying accuracy is high, which makes it difficult to do it under on-site construction conditions, resulting in poor crossing quality. high
