Description
Technical field
The utility model belongs to constructing tunnel apparatus field, and in particular to a kind of piecemeal pin-connected panel variable cross-section lining trolley.
Background technique
In constructing tunnel design, due to the difference of geological type, tunnel turning radius is also variant, and different tunnels is cut
Face size is different, and each section of sectional dimension can also change in same tunnel.During Tunnel Second Lining Construction, single line iron
Road tunnel cross-section space is small, section widen variation it is more, there is also sections of casting anchor for long distance tunnel, meet tunnel with 1 trolley
The two lining constructions in multibreak face, trolley design difficulty are bigger.Need trolley portal-framed structure type selecting, column and lead screw connection and
More reasonable design method is selected in the add wide way of template, comprehensively considers the design object to realize trolley.
In narrow space, to guarantee vehicle pass-through space, portal-framed structure will compress.Door frame sectional dimension reduces,
Resist torque ability just becomes smaller, and when pouring side wall concrete construction, door frame lower part is easy to produce interior crowded deformation, to prevent door frame
Deforming at present has following three kinds of design methods.
Method one: for template lower anchor on short abutment wall embedded bar, this method template power transmission is most directly also most simple
Single design method, but need that embedded bar is installed in the construction of short abutment wall, process is increased, construction teams and groups are reluctant using this
Kind method.
Method two: side form lower part is connected on the outside of walking beam by lead screw, increases horizontal screw lead between door frame walking beam
Support, when construction, are convenient for disassembly and assembly easy to operate, are most common design methods.This method makes trolley serve as a contrast concrete two
Passing through for vehicle is hindered when pouring construction, is in fact single line channel in tunnel, is guaranteed in the solidifying native pouring construction of two linings
The supply of concrete, only a current tank car no longer passes through other vehicles.
Method three: trolley increases channel base plate, is withstood on bottom plate in side form bottom by diagonal brace, and vehicle leads on bottom plate
Row.Trolley in this way does not influence the passage of vehicle, but increases the gross weight of trolley, and bottom plate has 20-30cm's
Thickness, to guarantee that vehicle passes through space it is necessary to improve the big depth of beam of door frame, often space limitation cannot be met the requirements.Therefore
This method is not used generally.
Since space limits, door frame column sectional dimension is smaller, and the space between side form is relatively narrow, between door frame and side form
Lead screw connects design comparison difficulty, and usually there are two types of design methods.
Method one: welding variable cross-section composite box column, lead screw connection pedestal are hidden in cabinet.Advantage is column rigidity
Good, lead screw is connected to column center, and stress is direct；The disadvantage is that require technique high when column is processed, when construction the peace of lead screw tear open and
It adjusts inconvenient.
Method two: selecting suitable H profile steel, welds gusset, reinforces column, and lead screw connects tube chamber welds with base column side.It is excellent
Point is processing and fabricating simplicity, easy to control the quality；Lead screw peace is torn open and is adjusted and is easy to operate when construction；Disadvantage column poor rigidity, lead screw top
In column side, stress is bad, and lead screw connection pedestal is easily deformed.
What general trolley widened use is all that side form is constant, the method for widening of replacement addition block among backform, but to sky
Between narrow section, especially section variation be more and the biggish section of changing value, trolley section and tunnel can be made in this way
Road design section deviation is larger, is unable to satisfy construction requirement.
