Description
Technical field
The utility model relates to railroad maintenance and consolidates technical field, especially a kind of track strengthening structure.
Background technology
Along with the repeatedly speed raising of china railway, all fronts isolation that most of circuit carries out is closed.Therefore need to build on existing railway line a lot of on across or under the passage worn so that railway both sides pedestrian and vehicle is current.Underground frame bridge adopts pipe jacking method, instrument has occupation of land and removes few, interference on the road is little, the advantages such as speed is fast, quality is good, relative to bridge crossing, for adapting to existing railway speed-raising needs, link up railway both sides road traffic, cancel the level crossing of Frequent Accidents, under railway line, building overpass bridge with jacking be widely adopted, for ensureing being perfectly safe and normally running of railway and train, must reinforce rail track when frame structure construction jacking, therefore, for the problems referred to above, we propose a kind of route of pipe line ruggedized construction.
Utility model content
Prior art can not meet the needs of people, and for making up prior art deficiency, it is simple that the utility model aims to provide a kind of structure, science is reliable, tight stable, safety is high, and interference on the road is little, speed is fast, do not disturb railway signal, can ensure both wired traffic safety and box-body jacking time be obstructed minimum, guarantee line direction, height meet the requirements, there are good economic benefit and social benefit, practical route of pipe line ruggedized construction.
For achieving the above object, the utility model by the following technical solutions: a kind of track strengthening structure, at least comprises sleeper, longeron, sleeper buttress, steel plate, crossbeam, casing and concrete pad; Described longeron is arranged on directly over sleeper, and is connected by bolt between longeron with sleeper; Described sleeper is symmetricly set on sleeper buttress inner side and is close-coupled on end support; Described crossbeam be arranged on sleeper lower end and with sleeper soffit compact siro spinning technology; Described sleeper buttress is symmetricly set on immediately below longeron two ends; Described concrete pad is arranged on immediately below sleeper buttress, and steel plate is closely rabbeted in the middle of sleeper buttress with concrete; Described casing is symmetricly set on immediately below crossbeam.
As optimisation technique scheme of the present utility model: described longeron adopts i iron binding structure, and longeron i iron is connected with sleeper U bolt and buckle; Described crossbeam adopts i-beam structure, and between crossbeam and casing, space is provided with pad.
Compared with prior art, the beneficial effects of the utility model are: adopt hanger rail beam reinforcing mode in length and breadth, crossbeam adopts i iron, longeron should adopt i iron bundle, the connection of i iron adopts overlap joint or welding, crossbeam i iron is connected with hanger rail application U bolt and buckle, ensure structural integrity and stability, insulation rubber cushion is added between driving rail and i iron, prevent from disturbing railway signal, bridge top top rail fulcrum adopts Drag reduction devices, hanger rail adds beam in length and breadth should on the basis of hanger rail crossbeam, one group of I-shaped steel longitudinal beam consistent with railway direction is respectively added on crossbeam two ends, and adopt U bolt and buckle to be connected with crossbeam, for ensure both wired traffic safety and box-body jacking time be obstructed minimum, take the adjustment of the pad of track strengthening system and jack to rebuild circuit, Framed underpass bridge front track strengthening stage and the jacking rear trimming to circuit in place are mainly taked to tamp and rebuild ballast aggregate to realize, beat pine wedge during jacking, under making i iron, iron block plays a role, space sleeper buttress, timber wedge, iron block pad between crossbeam and casing, and row's pad is established in every jacking one to two meter, ensures overall firm, practical, is applicable to promoting the use of.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 2, in the utility model embodiment, a kind of track strengthening structure, at least comprises sleeper 1, longeron 2, sleeper buttress 3, steel plate 4, crossbeam 5, casing 6 and concrete pad 7; Described longeron 2 is arranged on directly over sleeper 1, and is connected by bolt between longeron 2 with sleeper 1; Described sleeper 1 be symmetricly set on sleeper buttress 3 inside and be close-coupled on end support; Described crossbeam 5 be arranged on sleeper 1 lower end and with sleeper 1 soffit compact siro spinning technology; Described sleeper buttress 3 is symmetricly set on immediately below longeron 2 two ends; Described concrete pad 7 is arranged on immediately below sleeper buttress 3, and steel plate 4 is closely rabbeted in the middle of sleeper buttress 3 with concrete; Described casing 6 is symmetricly set on immediately below crossbeam 5.
As optimisation technique scheme of the present utility model: described longeron 2 adopts i iron binding structure, and longeron 2 i iron is connected with sleeper 1 U bolt and buckle; Described crossbeam 5 adopts i-beam structure, and between crossbeam 5 and casing 6, space is provided with pad.
As Construction Attention thing top of the present utility model: hanger rail with sleeper U bolt and should be connected with buckle, rail Shu Benshen should fix every 15 meter of angle steel and U bolt; Hanger rail length should stretch out 15 meter, the every side of pontic and more than; Should three to five be overlayed outside pontic abutment wall, the connection of i iron can adopt overlap joint or welding, crossbeam i iron is connected with hanger rail application U bolt and buckle, bridge top top rail fulcrum should adopt Drag reduction devices, hanger rail adds beam in length and breadth should on the basis of hanger rail crossbeam, one group of I-shaped steel longitudinal beam consistent with railway direction is respectively added on crossbeam two ends, and adopt U bolt and buckle to be connected with crossbeam, jacking post, top iron, jack are installed in jacking from rear back beam, on the same line, jack installing space is 50 centimetres to three's axis; Center line and elevation should be measured after terminating in examination top, find that deviation can adjust on slide plate, if all are normal, can pressurize and carry out normal jacking; Shoveling is accomplished with digging Sui Ding, the earthwork need to look into after digging out qualified after can jacking, will ensure during shoveling that left and right synchronously puts in place, can take unequal top, both sides power method when adjustment direction controls, high process control can adopt the method supporting and enter to eat native machine to increase nose-up pitching moment.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
