Abstract
The utility model provides a railway large -span overhead line protective structure, it includes D24m just roof beam, D16m just under roof beam, the line structure, stake columnar pier, enlarge basic abutment, characterized by: D24m just roof beam and D16m just the roof beam meet the below of department and be provided with a columnar pier, just be provided with and enlarge basic abutment in the outer end below of roof beam at D16m, set up structure under wired between two stake columnar piers. The utility model discloses because set up and the adoption of stake columnar pier simultaneously in three holes just roof beam, has prevented that the circuit from caving in, has increased circuit protection scope, effective structure width can reach 22m, highly reaches more than the 10m the minimum 0.375m that is of the flange of rail to structrual height. This protective structure has that the construction method is simple, the protection scope is big, under line structure free height, and the advantage of economy and durability and environmental protection.
Description
Technical field
This utility model relates to technical field of building construction, particularly a kind of Long Span Railway overhead transmission line safeguard structure.
Background technology
In construction of railway project field, often passing through viaduct or pipeline etc. below operating line, in order to not affect the operation of circuit, general employing is empty by existing coil holder, constructs below safeguarding structure.It is typically based on the protection method that new construction size uses and has rail beam, single hole just beam, steel beam structure and I-steel etc. in length and breadth, but work as structure width
>10m
, highly
>5m
Time, i-beam structure in length and breadth can only be used, this structure is big to the most wired interference, and costly, difficulty of construction is big.
Summary of the invention
This utility model purpose is to provide one and meets on the premise of the most wired operation, uses the safeguard structure of large span overhead transmission line to realize the Long Span Railway overhead transmission line safeguard structure of structure construction under line.
This utility model is achieved in that it includes
D24m
Just beam,
D16m
Just structure, pile-column bridge pier, Extended chemotherapy abutment under beam, line, is characterized in that:
D24m
Just beam with
D16m
Just beam connects
The lower section at place is provided with pile-column bridge pier,
D16m
Just beam
It is provided with Extended chemotherapy abutment below outer end, wired lower structure is set between two pile columnar piers.
This utility model sets up and the employing of pile-column bridge pier due to three holes just beam simultaneously, it is therefore prevented that circuit caves in, and adds line protection scope, and resulting structure width can reach
22m
, highly reach
10m
Above, the flange of rail is minimum to structure height
0.375m
.Have that construction method is simple, protective range big, structure free height under line, and economy and durability and the advantage of environmental protection.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is further described；
