Description
Technical field
The present invention relates to technical field of tunnel construction, more particularly, to a kind of formwork jumbo, relate more specifically to one kind and pour
The integral mold plate chassis using during Railway Tunnel ditch cable trench.
Background technology
At present, in the construction of Railway Tunnel ditch cable trench, need each position chi to concrete works with template
Very little it is controlled.Traditional concrete mould method of plate installation is: carries out assembly using fritter punching block according to scantling, and makes
Supported with rod member, so that the locus of template is fixed.Although the method has the characteristics that modular shuttering element is light and convenient transportation, work
Effect is low, and construction cost is high, and appearance quality trait is difficult.
Disclose two kinds of integral mold plates used in the construction of Railway Tunnel ditch cable trench in prior art to move
Dynamic chassis, but also there is the defect of following four aspect in both technical schemes:
Firstth, two kinds technical schemes all employ the shaped steel frame of falling l as support girder, and its shortcoming is: works as one-off construction
When length is more than 8 meters, the amount of deflection of support girder can gross distortion design and code requirement it is impossible to meet；When length of once constructing
During less than 8 meters, the amount of deflection of support girder will not gross distortion, but construction cycle-index increases, lead to construction effect to reduce and
The problem that construction cost increases.
Secondth, one of which technical scheme is to carry out form removal by angle plus bayonet lock, due to the side pressure after concreting
Power makes frictional force increase, and form removal is very difficult in this way；Another kind of technical scheme is using setting demoulding expansion joint
To facilitate form removal with demoulding fixture block, to need after concreting first to clear up the concrete at demoulding expansion joint, then carry out form removal, by
In lateral sulcus ditch depth and its section is narrow, concrete is removed very difficult, often can only pound steel form using striking in this way
Or the method that lifted carrys out form removal by force, thus leading to template deformation, repairing template and will consume the plenty of time.
3rd, two kind of technical scheme is all to complete secondary lining using being fixed on cross-brace one end of integral mold plate
Method on concrete surface, to solve the problems, such as Overall Steel Formwork positioning and to fix, but, complete the secondary lining constructed
Due to the reason such as reserved of constructing, possible line style is not on the same line, laterally inclined after the completion of leading to ditch cable trench to be constructed in face
Difference is not it may appear that meet design and the problem of code requirement.
4th, running gear when mobile with regard to integral mold plate, two kinds of technical schemes are respectively adopted: a single front-wheel
Method with arranging double movable pulley under the counterweight beam of side, both approaches, when mobile, be required to heavy mechanical equipment and join
Close, mobile inconvenience, and completed concrete corner is easily broken by moving process.
Therefore, for above deficiency, it is desirable to provide a kind of use during Railway Tunnel ditch cable trench removable of pouring
Dynamic integral mold plate chassis.
Content of the invention
