Description
Technical field
The present invention relates to subgrade engineering, in particular to a kind of cutting engineering of heavy grade cogwheel railway.
Background technique
Cogwheel railway is a kind of very strong railway of grade climbing performance, therefore the longitudinal slope of route can be larger, cogwheel railway usually handle
Focal point concentrates in the relationship of train and track, but the effect of track and ballast, ballast and road bed in fact is also very heavy
It wants, such as ballast and when rolling frictional resistance deficiency between smooth road bed, ballast cannot provide enough effective resistances for track
Power, if road bed is made into coarse structure, ponding is not easy to exclude, and can soften road structure；In track masterpiece when the gradient is larger
It can also be reduced with the ballast stability of lower road bed track two sides.Therefore it proposes a kind of cutting heavy grade cogwheel railway structure and constructs
Method is of great significance, and conducive to the economy, ring for guaranteeing that operation safety, the cogwheel railway of heavy grade cogwheel railway are built
Protect property and be conducive to promote and apply.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of cutting heavy grade cogwheel railway structures, to greatly enhance
The overall stability and anti-slide performance of quarrel, it is ensured that the safety of heavy grade cogwheel railway, and there is good economy.
It is as follows that the present invention solves the technical solution that above-mentioned technical problem is taken:
A kind of cutting heavy grade cogwheel railway structure of the invention, including being set to the gutter of roadbed both lateral sides, filling out
The roadbed surface layer between the abutment wall of two sides gutter inside is built, and fills the ballast on roadbed surface layer, track structure buries
It is located at the top of ballast, it is characterized in that: being laid with the friction pad fixed by U-shaped nail, U between roadbed surface layer top surface and ballast bottom surface
The setting of sprig interval, its underpart pass through friction pad and are fixed in roadbed surface layer；The gutter is the different high side wall of armored concrete
Structure, inside abutment wall extend to form high side wall vertically upward, roadbed surface layer, ballast fill in two sides gutter high side wall it
Between.
Another technical problem to be solved by this invention is to provide a kind of side of constructing of cutting heavy grade cogwheel railway structure
Method, this method comprises the following steps:
1. stage excavation cutting simultaneously carries out side slope protection in time, until roadbed surface layer cope level；
2. excavating gutter foundation pit, and construction drainage ditch in time, and drain hole is reserved on the high side wall in gutter；
3. being excavated between the high side wall of two sides gutter after the concrete strength in gutter reaches the 75% of design strength
Ground foundation pit；
4. placement in layers roadbed surface layer, roadbed surface layer is in the filler close to gutter high side wall side 0.2-0.5m width range
The cement of 3% weight of middle incorporation；
5. being laid with friction pad on the top surface of roadbed surface layer, and tense exceptionally straight；
6. U-shaped nail is inserted at interval on friction pad, U-shaped nail lower part passes through friction pad and is fixed in surface layer of subgrade bed；
7. making ballast and vibratory compaction are to track structure Bottom Altitude at the top of friction pad；
8. being put into track structure at the top of ballast, making residue ballast and vibratory compaction between track structure.
The invention has the advantages that it is laid with and fixes the friction pad of one layer high friction in smooth roadbed surface layer top surface,
So that ballast will not generate sliding on roadbed surface layer, so as to provide enough frictional resistances for track structure, and by road
Abutment wall is increased to form high side wall on the inside of the gutter of base two sides, can play the role of blocking to ballast, greatly enhance the whole of ballast
Body stability and anti-slide performance, it is ensured that the safety of heavy grade cogwheel railway；High side wall had both avoided ballast from laterally occurring in roadbed
It is unstable, and width of the subgrade surface is reduced, to save the area and reduce cutting amount of excavation, there is good economy；Close to
Gutter high side wall side 0.2-0.5m range mixes the cement of constant weight in the filler of roadbed surface layer, both conducive to roadbed surface layer
Consolidation effect is filled, and reduces infiltrating for water, Infiltration water can be discharged by being set to the drain hole of high side wall；Construction method behaviour
Make simply, system easy to control the quality is conducive to cost saving, can be in large-scale application.
