Description
Technical field
The utility model relates to a kind of urban highway traffic rail system, particularly relates to a kind of split type continuous support without fastener ballast bed system, belongs to technical field of rail traffic.
Background technology
In traditional track traffic, rail is fixed together by fastener and track or sleeper, and be then positioned on the tiny fragments of stone, coal, etc. or ballastless track bed, in whole work progress, operation is more, and construction period is longer, and comparatively large to surrounding environment influence, efficiency of construction is low; Fastener in use easily loosens, and in order to guarantee driving safety, need frequent contacting piece carry out inspection and again tighten, maintenance workload is large, and cost is high; In addition, conventional rails rail is directly exposed in air, and what the noise produced in driving conditions and vibration can be a large amount of is radiated surrounding environment, huge on nearby residents life impact; Meanwhile, drive mechanism and material are considered less in environmental protection.
In order to solve the above-mentioned technical problem of conventional rails, someone proposes the problem adopting embedded tracks to solve noise, if application number is 200720097924.3, notification number is CN201103082Y, name is called the Chinese utility model patent of " embedded load-bearing rail ", it discloses a kind of embedded load-bearing rail, specifically disclose one and have priming paint topping on Rail Surface and the flange of rail, steel concrete railway roadbed is fixed with rail support groove by bearing, be provided with the first insulating pad and second insulating pad of adjustment track level measuring and the flange of rail gradient every 1-2 rice in rail support groove, be respectively arranged with the first block adjusting track lateral attitude and the second block in the position that rail both sides are corresponding to two insulating pads, in-orbit bottom face, be provided with the resin fillers of the locking rail bonding with rail and rail support groove between steel rail web and rail support groove.Although shock loading and oscillating load that train puts on rail effectively can be cushioned at the bottom of this embedded bearing rail, play the effect of vibration damping and minimizing noise; But also there is following shortcoming in the Load-bearing rail of this structure:
1, this embedded load-bearing rail mainly to adopt and supports, and its support effect is not good, and backing plate is played a supporting role below rail, and backing plate is interrupted and lays, cannot continuous laying;
2, fastener or other anchoring pieces is needed to be fixed;
3, this embedded load-bearing rail carries out in steel plate groove, is not directly to carry out in prefabricated road bed board;
4, this embedded load-bearing rail by weight area little, be merely able to for standard gauge use, in grooved rail, use inconvenience, and and unresolved conventional rails is constructed slow problem.
Utility model content
The purpose of this utility model is: provide a kind of split type continuous support without fastener ballast bed system, solving existing embedded tracks, to there is effect of vibration and noise reduction not good, the impact of construction climate is large, complex process, later maintenance job requirement is many, the technical problem that cost is high, thus can effectively solve above-mentioned problems of the prior art.
The purpose of this utility model is realized by following technical proposals: a kind of split type continuous support is without fastener ballast bed system, comprise concrete railway board and concrete rail support groove, concrete rail support groove is located at the top of concrete railway board, and there is gap between the two, establish cast-in-situ concrete articulamentum in gap between; Concrete rail support groove is prefabricated component, and in a row arranges continuously; Be provided with rail, backing plate and polymeric filler in described concrete rail support groove, the bottom of rail is located at by described backing plate, and backing plate is continuous laying below rail, and is adhered to one with concrete rail support groove, and polymeric filler is located at the outside of rail.
As preferred embodiment, at the left and right sides horizontally set conduit respectively of concrete rail support groove bottom.
As preferred embodiment, be provided with steel plate in the outside of polymeric filler.
As further preferably, described rail be " work " font, and polymeric filler is " work " font of correspondence with it, the left and right sides on steel plate is located at " work " font top.
As preferred embodiment, the bottom connection of described backing plate and rail touches.
As preferred embodiment, be provided with filling soil in the outside of concrete rail support groove and cast-in-situ concrete articulamentum.
In the utility model, the effect of part is as follows:
1, rail: can be grooved rail or common rail, rail needs to carry out the floating rust process in surface before use, and carries out corresponding primary coat process to ensure the bonding of later stage and associated materials.
2, backing plate: adopt polyurethane foam backing plate to make, this backing plate adjustable length, preferred length is 1 meter or 1.5 meters; Backing plate is continuous laying below rail, and this point is different from conventional rails, and the backing plate of conventional rails plays the effect of supporting, and is be interrupted to lay, and polyurethane foam backing plate is also bonding with at the bottom of concrete pit by bonding agent, thus fixing.
3, concrete rail support groove: this groove size and dimension can change according to designing requirement, is provided with boss in groove, can effectively lock rail and prevent rail expansion.
4, cast-in-situ concrete articulamentum: concrete rail support groove is laid in place, height and the suitable cast afterwards of gauge adjustment, for fixing concrete rail support groove, make it to be integrally connected with concrete railway board.
5. concrete rail support groove and concrete railway board: concrete rail support groove is prefabricated component, concrete railway board also pre-sets, and when mounted, only needs concrete rail support groove to be put on concrete railway board, then cast-in-place concrete between, as articulamentum.
Compared with prior art, the beneficial effects of the utility model: the split type continuous support of the utility model is without fastener ballast bed system, and can meet the needs of existing urban traffic, the feature of environmental protection is high, specifically, possesses following advantage compared with existing embedded tracks:
1. the line construction cycle is shorter: concrete rail support groove separates with concrete railway board by this split type ballast bed system, makes separately, reduces complexity and the weight of prefabricated component, is convenient to produce, transport and construction;
2. construction quality more easily ensures: the rail support groove part in this split type ballast bed system can fulfil making ahead of schedule in factory, avoids weather environment and lays a railway track on job site and the impact of the rail that locks, and the track that can effectively lock, prevent rail expansion;
3. be convenient to safeguard, change, the extension wire life-span: when certain part needs to safeguard in this split type ballast bed system circuit, because its concrete track groove is prefabricated component, and adopt continuous print mode to arrange, therefore, only need damaged part to pull down to change, greatly reduce maintenance cost and maintenance time;
4. track structure height is more easy to control, and can effectively shake and noise by control circuit: adopt continuous laying, laying efficiency is high.
