Abstract
The present invention relates to a kind of resistance flue tiny fragments of stone, coal, etc. covering layer.Railway ballast in Ballast track railway line is exposed shape, and sand and dust, coal dust easily enter railway ballast hole, make plate knot of ballast bed, and track elasticity declines, and then the track component stresses such as rail, fastener, sleeper are worsened, aging, acceleration of losing efficacy.Resistance flue tiny fragments of stone, coal, etc. covering layer of the present invention is laid on railway roadbed surface, and the splicing of direction along ng a path block-by-block is arranged; The tectal central authorities of every block are core, arrange groove type and become drainage groove in the middle part of road core; Road core both lateral sides is tiny fragments of stone, coal, etc. scapulet, tilts respectively to road core; Tiny fragments of stone, coal, etc. scapulet lateral outer side is side slope plate, and side slope plate tilts to stretch to ground.The present invention can meet railway line, the laying demand of field to hair line, loading and unloading track of standing that wind-engaging sand shadow rings area, meet railway clearance requirement, there is certain intensity, good endurance, does not affect railway roadbed draining, does not affect track circuit, material environment friendly, the equipment that do not affect is installed and maintenance, and conveniently assemble and disassemble is safe and reliable.
Description
Technical field
the invention belongs to railway construction technical field, be specifically related to a kind of resistance flue tiny fragments of stone, coal, etc. covering layer.
Background technology
At present, in the railway line of laying Ballast track, railway ballast is exposed shape, the fine particle such as sand and dust, coal dust is easy to enter railway ballast hole, and progressively sink along with train vibration, make plate knot of ballast bed, track elasticity declines, and then the track component stresses such as rail, fastener, sleeper are worsened, aging, acceleration of losing efficacy.It is very necessary for carrying out in good time cleaning to railway roadbed, but time-consuming, and affects circuit normal pass efficiency.Laying non-fragment orbit is another kind of solution, but prerequisite is that under line, basis must be stablized, and need strengthen engineering treatment, and non-fragment orbit itself costly in addition, and therefore the method is very few because economy is costly adopts.
Summary of the invention
The object of this invention is to provide and a kind ofly can effectively prevent from dust from entering railway ballast hole causing plate knot of ballast bed and the lower resistance flue tiny fragments of stone, coal, etc. covering layer of construction cost.
The technical solution adopted in the present invention is:
Resistance flue tiny fragments of stone, coal, etc. covering layer, is characterized in that:
Described resistance flue tiny fragments of stone, coal, etc. covering layer is laid on railway roadbed surface, and the splicing of direction along ng a path block-by-block is arranged;
The tectal central authorities of every block are core, arrange groove type and become drainage groove in the middle part of road core; Road core both lateral sides is tiny fragments of stone, coal, etc. scapulet, tilts respectively to road core; Tiny fragments of stone, coal, etc. scapulet lateral outer side is side slope plate, and side slope plate tilts to stretch to ground.
Described Zha Jianbanchu arranges the fluting being used for fastener and installing.
The length of described covering layer direction along ng a path is 60-120cm, and thickness is 1.5-3cm.
Each block of described covering layer direction along ng a path is connected by pin.
Described covering layer adopts glass fiber reinkorced concrete, glass fiber reinforced plastics or inorganic glass fiber reinforced plastic material.
The present invention has the following advantages:
The railway ballast covering layer that prevention dust involved in the present invention enters, cost economic, can meet railway line, the laying demand of field to hair line, loading and unloading track of standing that wind-engaging sand shadow rings area, meet railway clearance requirement, there is certain intensity, good endurance, does not affect railway roadbed draining, does not affect track circuit, material environment friendly, the equipment that do not affect is installed and maintenance, and conveniently assemble and disassemble is safe and reliable.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention will be described in detail.
One resistance flue tiny fragments of stone, coal, etc. covering layer of the present invention, be laid on railway roadbed surface, prevent dust from entering and cause plate knot of ballast bed, meet a series of technical requirementss such as gauge, intensity, draining, environmental protection, track circuit, equipment installation, maintenance, other regarding safety simultaneously.
Resistance flue tiny fragments of stone, coal, etc. covering layer adopts prefabrication, on-site consolidation product, 3 pieces or more laterally can be divided into according to railway ballast transverse shape, the splicing of direction along ng a path block-by-block is arranged, each block of covering layer direction along ng a path is connected by pin, and the length of every block covering layer direction along ng a path is 60-120cm, and thickness is 1.5-3cm, every block weight 10 ~ 40kg, be close to railway roadbed surface to lay, covering layer not higher than 100mm below orbital plane, meets the requirement of track clearance after having laid.Adopt glass fiber reinkorced concrete (GRC), glass fiber reinforced plastics (FRP), FRIM or other macromolecule polymer material, these materials have the performances such as acid and alkali-resistance greasy dirt burn into is ageing-resistant, there is anti-flammability, pollution gas is not produced during fire, meet environmental requirement, there is good insulating properties, meet the requirement of track circuit.
The tectal central authorities of every block are core 1, and width is 130-150cm, arranges groove type and become drainage groove in the middle part of road core 1, and drainage section is long-pending is not less than 300cm
2; Road core 1 both lateral sides is tiny fragments of stone, coal, etc. scapulet 2, and width is 50-70cm, tilts respectively to road core 1; Tiny fragments of stone, coal, etc. scapulet 2 lateral outer side is side slope plate 3, and width is depending on the height of concrete railway roadbed, and side slope plate 3 tilts to stretch to ground.Wherein, tiny fragments of stone, coal, etc. scapulet 2 place arranges the fluting being used for fastener and installing.
Railway ballast covering layer requirement of strength is, under every square meter vacant state, load-bearing load is not less than 5kN, and after freeze thawing, anti-folding load is not less than 500N(-40 DEG C of Frozen-thawed cycled 25 times, is a base unit with 2 hours).Railway ballast covering layer meets fastener and safeguards space requirement, forms size and is not less than the breach of 350mm × 200mm often locating fastener place, and meet miscellaneous equipment installation requirement.In FIG, first align during connection the pin in sub-block and the breach on mother tuber, then by automatically snapping in after traversing horizontal alignment, easy disassembly, simultaneously longitudinally forming continuous structure, ensureing not started under wind-force effect, guaranteeing safety.In FIG, should according to the rainfall product data of locality during installation, the mouth of a river under a reserved place at a certain distance, in the middle part of Ji road heart covering layer, stream is empty, meets drainage requirement, ensures that track circuit is unaffected simultaneously.
Content of the present invention is not limited to cited by embodiment, and the conversion of those of ordinary skill in the art by reading manual of the present invention to any equivalence that technical solution of the present invention is taked, is claim of the present invention and contains.
