Description
Technical field
A kind of automatic inverted arch trestle is the utility model is related to, belongs to tunnel or underground engineering technical field of concrete construction.
Background technology
With the progress of China's tunnel construction technology, to the requirement more and more higher of the mechanization of inverted arch construction, although at present
There is part producer to provide mechanical inverted arch trestle, but trestle work structure complexity be present, input is big, heavy, malfunction,
The shortcomings of security performance is not high, it is impossible to carry out the popularization of large area.In constructing tunnel, the section-bottom arc of excavation is referred to as
Inverted arch；And in the work progress at tunnel inverted arch position, inverted arch trestle need be set up in inverted arch excavation face, before connecting tunnel
The excavation face at end and tunnel rear end fill surface passage, fill surface are term when inverted arch carries out concrete construction, inverted arch trestle
In the presence of tunnel excavation outwards to slag tap to transport not applied by inverted arch into hole with material to be influenceed, inverted arch concrete construction ensure that
Continuously carried out simultaneously with tunnel excavation.It is but insufficient below the trestle generally existing used in construction at present：
1. traditional trestle uses I-steel Site Welding, weight weight, and I-steel does not have self-power system, moves
It is dynamic to be required for usage mining machine to carry in place, although this method cost is cheap, span very little, it can not just use and dig when span is too big
Pick machine is carried, and is applied man-hour requirement and is frequently moved using power-equipment, very inconvenient.
2. dynamical system is installed additional on traditional trestle work structure in part producing producer, make trestle can be with automatic moving, traditional skill
Although the trestle span of art can reach 12 meters or so, in order to meet it is basic walk, the function such as traversing, its is complicated, deposits
It is not convenient what is used.
3. the trestle of part producing producer mitigates main bridge weight using both sides truss+center-aisle structure, further increase
Main spanning degree；The construction length of trestle is set to reach 16 meters or so.But because truss structure structure bulky, use are ineffective
Living, the speed of travel is slower.
4. to meet the needs of design function, in many structures of Front-end Design of trestle, the shadow in the use of reality
The excavation of front end is rung, while the safe cloth of tunnel excavation possibly can not be met away from requiring.
5. the trestle of large span used by constructing at present, a certain specific construction method is often only can be suitably used for, especially
It is the excavation tap cinder construction of inverted arch bottom to be taken into account, it is necessary to increase trestle pedal, trestle total length is at least increased by more than ten
Rice, when clearing up bottom ash, pedal and trestle need all to return back in the inverted arch fill surface for accomplishing fluently concrete, on the one hand retract non-
Often trouble, the construction of another aspect follow-up link are too far apart, feed and slag tap to produce and interfere, do not solve well still
Certainly method so that the application of trestle is by strong influence.
6. at present meet construction length requirement simultaneously, tunnel excavation there has also been the requirement of full face tunneling, for stack
Putting for bridge front end has higher requirement with preceding access bridge angle position, with the trestle of current existing species, can not realize flowing water
Operation is constructed.
