Abstract
The utility model discloses a kind of railway internal connecting type box-shaped and contain nodule structure, contain joint including a single linear meter(lin.m.) box-shaped being arranged on culvert joint place new, old, this culvert saves one end and is connected with existing culvert, and aperture and clear height keep consistent with existing joint of containing；The other end is connected with newly-built culvert, and aperture and clear height keep consistent with newly-built joint of containing；This list linear meter(lin.m.) contains the uiform section saving the outer contour formation closing of each cross section, and its inner outline forms the variable cross-section closed；Its aperture and clear height to newly-built culvert size gradation by existing culvert size, are formed internal connecting type and contain nodule structure.
Description
Technical field
This utility model relates to a kind of railway internal connecting type box-shaped and contains nodule structure.
Background technology
During existing line operated reorganization and expansion, at the parallel paragraph that distance between centers of tracks is less, existing culvert need to be carried out spreading transformation.According to " railway bridges and culverts design fundamental norms " TB10002.1-2005 relevant regulations, combine working condition and the practical experience of workman of maintenance, various culvert is according to its clear height or internal diameter, it is stipulated that its no more than limited length.
But when extension culvert, often the total length after spreading has exceeded limited length, spreading part is often used the culvert joint of larger aperture, or the culvert joint of higher clear height by design, meets the requirement of limited length, improve the working condition of maintenance.If existing culvert and spreading part are all that box-shaped is contained, the box section docking that aperture is different from clear height, to contain internode and produce bigger faulting of slab ends gap, subgrade soil will pour into inside culvert along gap.
When existing culvert is contained for circle, it is easily generated alluvial, for improving flow condition, and combines the principle progressively transformed, how spreading part is used box-shaped to contain by design.Newly, old culvert pattern different, circular cross-section is docked with box section, contains internode and produces bigger faulting of slab ends gap, and subgrade soil will pour into inside culvert along gap.
Processing mode during practice of construction, first it is that existing adjacent lines is properly protected, then excavate roadbed, remove existing culvert eight word aileron, afterwards in parallel circuit direction, existing culvert both sides, cast concrete retaining wall or headwall, contain top and set up concrete block, to block culvert joint faulting of slab ends gap, it is to avoid subgrade soil pours into.This way needs at the most wired lower cast concrete structure, the maintenance corresponding time, after works intensity reaches design requirement, can carry out next step construction, and the safeguard procedures of adjacent lines need to set up always during this period.
Summary of the invention
The purpose of this utility model is to provide a kind of railway internal connecting type box-shaped to contain nodule structure, it is possible to meets culvert two internode faulting of slab ends detailing requiments new, old, reduces the most wired lower working procedure, shortens the guard time near existing line road.
The purpose of this utility model is achieved in that a kind of railway internal connecting type box-shaped contains nodule structure, contains joint including a single linear meter(lin.m.) box-shaped being arranged on culvert joint place new, old, and this culvert saves one end and is connected with existing culvert, and aperture and clear height keep consistent with existing joint of containing；The other end is connected with newly-built culvert, and aperture and clear height keep consistent with newly-built joint of containing；This list linear meter(lin.m.) contains the uiform section saving the outer contour formation closing of each cross section, and its inner outline forms the variable cross-section closed；Its aperture and clear height to newly-built culvert size gradation by existing culvert size, are formed internal connecting type and contain nodule structure.
This culvert joint two ends joining place, because aperture and clear height all use identical size, therefore does not produce culvert internode faulting of slab ends and gap.After prefabricated completing, then row excavation roadbed, can remove eight word ailerons, directly spreading position treated by lifting to existing culvert, can carry out next step construction.This utility model structure, without carrying out the cast of the most wired lower concrete structure, decreases the time of supporting, formwork erection, cast, form removal, health preserving, decreases the required line protection time simultaneously.It is that existing culvert contains joint with the transition between newly-built culvert that internal connecting type contains nodule structure, can be the most prefabricated.Containing joint two ends uses different wall thickness dimension prefabricated, aperture can be realized, box-shaped that clear height is different contain between transition；And contain joint two ends and use different section forms prefabricated, then can realize circle and contain the transition contained to box-shaped.
This utility model, while meeting culvert two internode faulting of slab ends detailing requiments new, old, is poured into a mould the operation of concrete structure and corresponding time, is decreased the required line protection time simultaneously after decreasing circuit excavation.Thus, accelerate construction speed, improve the safety of circuit operation.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.

In figure: the most existing roadbed body；2. help the basic body of broad way；The most existing culvert；4 newly-built culverts；5. internal connecting type contains joint；
6. internal connecting type contains joint outer contour；7. internal connecting type contains inner outline inside joint；8. internal connecting type contains inner outline outside joint；9. contain the joint concrete transitional surface with label；12. circuit ballast aggregates；13 gateway eight word ailerons.
Detailed description of the invention
A kind of railway internal connecting type box-shaped contains nodule structure, as shown in Figure 1, Figure 2, Figure 3 shows, contains joint including a single linear meter(lin.m.) box-shaped being arranged on culvert joint place new, old, and this culvert saves one end and is connected with existing culvert 3, and aperture and clear height keep consistent with existing joint of containing；The other end is connected with newly-built culvert 4, and aperture and clear height keep consistent with newly-built joint of containing；This list linear meter(lin.m.) is contained the internal connecting type in each cross section of joint and is contained the uiform section that joint outer contour 6 formation is closed, its inner outline forms the variable cross-section closed, i.e. internal connecting type is contained inner outline 7 and internal connecting type inside joint and is contained the variable cross-section forming closing outside joint between inner outline 8, and internal connecting type is contained inner outline 7 inside joint and contained with internal connecting type outside joint and to be connected with the concrete transitional surface 9 of label by containing joint between inner outline 8；The aperture of internal connecting type culvert joint 5 and clear height to newly-built culvert size gradation by existing culvert size, are formed internal connecting type and contain nodule structure.
This internal connecting type contains joint 5 two ends joining places, because aperture and clear height all use identical size, therefore does not produce culvert internode faulting of slab ends and gap.Can be after prefabricated completing, then row excavates existing roadbed body 1, removes gateway eight word aileron 13, and directly spreading position treated by lifting to existing culvert, the structure side basic body of broad way 2 and widen circuit ballast aggregate 12.This utility model structure, without carrying out the cast of the most wired lower concrete structure, decreases the time of supporting, formwork erection, cast, form removal, health preserving, decreases the required line protection time simultaneously.
