Abstract
The invention relates to a reinforced fiber composite sleeper for supporting railway tracks. The reinforced fiber composite sleeper is one made from reinforced fiber materials, fiber felts or weaving cloth through resin impregnation, formed by the pultrusion of a forming die for designing the shape of the section and solidified in the forming die. The invention overcomes the defects of the known techniques, has ideal strength and elasticity and good insulating property compared with the common concrete sleeper and the anticorrosive wooden sleeper, and ensures the safe running of the trains. In addition, with the good elasticity, the reinforced fiber composite sleeper greatly enhances the whole elasticity of the track structure and reduces the influence on roadbeds from the vibration of the trains and the environmental pollution from the noise of the trains during running; with the good insulating property, the reinforced fiber composite sleeper has no influence on the track circuits so as to ensure the safe running of the trains. The invention has the advantages of simple manufacturing, easy forming and short production period, and is capable of realizing the mechanical and continuous production. Besides, the length of the reinforced fiber composite sleeper can be cut and processed according to the determined length requirements, and the waste sleepers can be treated and recycled easily.
Description
Technical field
The present invention relates to a kind of sleeper that is used for the rail track supporting rail, particularly a kind of fortifying fibre composite sleeper.
Background technology
The sleeper of rail track use at present mainly is sleeper and prestressed reinforced concrete sleeper.
Known sleeper since it have good springiness, be easy to processing, advantage such as easy to use, on special locations such as bridge, track switch, be used widely.But owing to draw materials, the intensity of sleeper and durable even inadequately can strengthen dynamic action between wheel and rail, makes that the application life of sleeper is short.Its failure cause is a lot, mainly is rotten, mechanical wear and cracking.In addition, the high-quality timber resources is relatively deficienter, does not also more and more meet environmental protection and ecological protection requirement.
Known prestressed reinforced concrete sleeper is easy to guarantee manufactured size because its abundant raw materials, is convenient to prefabricatedly in enormous quantities, and quality is big, the life-span is long, and can improve the stability of track, therefore obtains extensive a large amount of use in China and world's railroad track.But prestressed reinforced concrete sleeper also exists drawbacks such as poor flexibility, rigidity are big, in the specific region or the position use and limited to.
The inventor is called " Crossties of glass fiber reinforced plastics and manufacture method thereof " (publication number: patent CN101289826A) disclosed of on November 22nd, 2008, the problems referred to above have been solved effectively, but in view of the restriction of material selection, structure design and preparation method thereof, the sleeper that only can be widely used in the little special location of use amount or have particular design to require.Can't satisfy in enormous quantities, serialization, mechanization production, be difficult to improve the fastener installation flexibility simultaneously.
What trunk railway lines adopted mostly at present is the track structure of rail and supporting prestressed reinforced concrete tie, the particularly all-round popularization of Line for Passenger Transportation in recent years, its rail, concrete sleeper, track plate quality are all very big, this heavy track structure increases orbit rigidity, can produce following adverse influence:
(1) bigger orbit rigidity can increase the mutual dynamic action between the wheel track, and serious meeting causes the especially hurt of axle box etc. of rolling stock traveling portion, influences the performance of running stability of rolling stock, particularly to the passenger vehicle of high-speed cruising, has reduced ride quality.
(2) vibration that produces during the train high-speed cruising and noise increase, and the living environment, the especially railway that have worsened the railway periphery are by locations such as city, rural area and historic site, ancient building areas.
(3) excessive orbit rigidity all can produce in various degree influence to special locations such as the bridges and culverts on the existing railway line, tunnel, changeover portion, ballast aggregate and city rail, subways.
In addition, the investment of production equipment of prestressed reinforced concrete sleeper is bigger, and the noise pollution that its production causes surrounding enviroment is bigger.The sleeper that simultaneously special location or position is had specific (special) requirements, production difficulty and technical requirements are difficult to guarantee.Simultaneously, in special location or the sleeper that adopts of position also be restricted because of timber resources is deficient.
The inventor is according to the experience and knowledge of being engaged in this area work for many years, for overcoming the above-mentioned defective of concrete sleeper, sleeper existence, address the above problem from material, structure and preparation method,, develop fortifying fibre composite sleeper of the present invention and manufacture method thereof through arduous research and development.
Summary of the invention
The technical problem to be solved in the present invention is: overcome that above-mentioned sleeper exists that intensity is low, durability not insufficient is even, the life-span is short and there are the defective that insulating properties are poor, rigidity is big in scarcity of resources and prestressed reinforced concrete tie, provide a kind of intensity height, elasticity height, good insulation preformance, ageing resistace is good, fastener is flexible for installation fortifying fibre composite sleeper, the vibration effect and the noise pollution that when its application will solve train operation preferably special sectors such as bridge, tunnel, track switch, subway, city rail will be produced.
For this reason, the fortifying fibre composite sleeper that the present invention proposes is through resin impregnation by reinforcing fiber materials, fibrofelt or woven cloth, by the moulding form pultrusion of design section shape, and the composite sleeper that makes it in mould, to solidify, described fortifying fibre composite sleeper is a hollow structure.
The manufacture method of above-mentioned fortifying fibre composite sleeper may further comprise the steps:
A, making sleeper model;
B, layout fortifying fibre, fibrofelt or woven cloth, and through resin impregnation;
C, the traction of employing large-tonnage pulling equipment;
D, device is cured moulding by being heating and curing;
E, length of sleeper as requested cut and process;
F, surfacing.
Characteristics of the present invention and advantage are:
Fortifying fibre composite sleeper of the present invention, overcome the defective of known sleeper and concrete sleeper, the advantage of having gathered existing sleeper and concrete sleeper, has the intensity and the elasticity that is much higher than sleeper higher than prestressed reinforced concrete sleeper, no any Insulation Problems has guaranteed the safe operation of train in the use.The good springiness of fiber composite sleeper before described the increasing has reduced in the train driving to the vibration effect of roadbed with to the noise pollution of environment, and is particularly particularly outstanding in this advantages of special location such as bridge, tunnel, track switch, subway, city rails.
Fortifying fibre composite sleeper of the present invention also has to be made simply, is easy to moulding, with short production cycle, can realize in enormous quantities, serialization, mechanization production, advantage applied widely.
