Description
Technical field
The present invention relates to the solidification of a kind of railway close railway roadbed and solidify the method closed, belong to Railway Transport Industry.
Background technology
The railway lines such as current rail yard, goods yard, power plant are mostly on roadbed lays stone ballast aggregate, repaves sleeper and steel-rail structure.Owing to having space between ballast aggregate, especially unload seam, when granule materials unloads on car, have many materials to fall within ballast aggregate, cannot clear up, not only form waste greatly, also cause ballast aggregate to pollute, affect circuit and stablize.For this reason, the coal yard special purpose railroad had at present directly railway roadbed is made concrete, but it is not owing to having ballast, and railway roadbed loses elasticity, have impact on the steady of vehicle pass-through, and very easily causes the damage of rail and wheel.
Along with the progress of high ferro technology, solid concrete roabed technology is applied unloading in seam, and the solid concrete roabed technology that namely seam have employed high ferro is unloaded by the Cao Fei pasture coal wharf as newly-built.But the solid concrete roabed adopting high ferro technical transform and come, construction technical requirement is high, invests huge, belongs to waste for goods yard, field of standing, the power plant industrial siding such as to unload coal relative to its travelling speed.For the rail yard built up, goods yard, power plant's industrial siding, transformation need circuit all to remove clean out after could construct, construction period is very long, invests huge, and this will have a strong impact on normal production and transport order.
Summary of the invention
Railway roadbed solidification is closed under being to provide a kind of condition stable at guarantee circuit by technical problem to be solved by this invention, makes railway roadbed smooth surface, and the railway solidification that railroad ballast is closed is closed railway roadbed and solidifies the method closed.
The present invention adopts following technical scheme:
The present invention adopts following technical scheme:
The method that railway ballast solidification of the present invention is closed adopts following steps:
One, ballast cleaning: first impurity in railway roadbed is removed clean, supplement or removing the ballast;
Two, gear quarrel wall is built: along toe ground, railway ballast both sides place excavation foundation ditch, tamp at the bottom of foundation ditch, beat 20-30cm 37 lime earth bed course, formwork supporting plate on 37 lime earth bed course, the gear quarrel wall of pouring reinforcement concrete is moved towards on downline road, on described gear quarrel wall, end face is L apart from the distance of rail bottom surface, and described L is 10-12cm; Gear quarrel wall arranges shrinkage joint and drain hole;
Three, railway roadbed is made firm by ramming: repeatedly made firm by ramming by the ballast aggregate in railway roadbed, mend quarrel, compacting, and in railway roadbed, immerse ballast aggregate glue or bituminous concrete or CA mortar, is tamped by ballast aggregate hole in railway roadbed;
Four, railway roadbed is closed and is built solidification: arrange elaxtic seal at railway roadbed top and between railway roadbed top and each side of sleeper, then build anti-crack concrete layer at elaxtic seal top, described anti-crack concrete layer top is smooth surface;
Described railway solidification is closed railway roadbed and is comprised the gear quarrel wall being separately positioned on railway ballast both sides, be located at the packing material in railway roadbed and be arranged on the anti-crack concrete layer at elaxtic seal top, at described railway roadbed top and between railway roadbed top and each side of sleeper, elaxtic seal is set, described packing material is ballast aggregate glue, bituminous concrete or CA mortar, described anti-crack concrete layer thickness is 8-15cm, described anti-crack concrete layer upper surface is P apart from the distance of rail bottom surface, described P is 8-10cm, the upper end face of described anti-crack concrete layer is higher than end face on gear quarrel wall,
Described anti-crack concrete layer reduces from railroad track center to railway roadbed both sides, and the gradient of reduction is 2%-5%;
Described anti-crack concrete layer is that steel fibre and ordinary concrete mix;
Described elaxtic seal is SBS modified asphalt waterproof coiled material.
Gear quarrel wall of the present invention is 30-60cm in the underground degree of depth, and height is on the ground 50-80cm, and end face width is 15-30cm; Described gear quarrel wall cross section is trapezoidal, and its side adjacent with railway roadbed is vertical plane, and its opposite side is inclined-plane, and the angle β of described inclined-plane and surface water plane is 50-70 ゜.
The spacing at the described shrinkage joint that the present invention is adjacent is 20-30m; The width at shrinkage joint is 5-10mm; Pitch spunyarn is set in shrinkage joint.
