Description
Technical field
The present invention relates to technical field of tunnel construction, in particular to a kind of tunnel fast lifting baffles.
Background technology
Maximum security risk is exactly arch cracking, chip off-falling and inverted arch protuberance in railway tunnel operation.Generate cracking chip off-falling
The main reason for there is at construction joint trolley rigidly squeeze, the cutting of waterstop cantilever end, the cold seam of concrete construction, coagulation at construction joint
Empty sound, voids and pits, sand, dusting etc. caused by native not full, concrete spillage, while difficulty of vibrating at construction joint, arch
Can not vibrate at construction joint, thus caused by operation tunnel disease it is very strange, but from influence concrete performance from the perspective of,
Most universal, most basic problem is still spillage.
Spillage can not be mainly completely superposed because back pressure type sealing is with seam when live inverted arch and lining cutting circumferential direction are constructed, and thus served as a contrast
Platform building cart easily causes spillage to will form the faulting of slab ends that can not close up after mould between back pressure type waterstop in casting process,
And irregular faulting of slab ends is formed, traditional handicraft is blocked using along lining trolley lower edge using wooden model, however wooden model exists
It is had the following problems during use：1, construction speed is slow, and during practice of construction, preliminary bracing profiled may not be too round
Suitable, end head formwork width differs when end being caused to be constructed, more so as to cause end wooden model block number, and blanking punch heavy workload is applied
Work is more slow；2, labor intensity is big, and every piece of wooden model securely must just can guarantee and not run the quick-fried mould of mould in reinforcing process, reinforces
Get up particularly cumbersome；3, closed matereial cycle rate is low, and wooden model is cut when blocking according to section configuration, construction next time after form removal
Utilization rate is quite low, causes wood consumption very big, increases construction cost.
Invention content
Based on problem above, the present invention provides a kind of tunnel fast lifting baffles.It is secondary that present invention can be implemented in tunnels
Faulting of slab ends during lining construction quickly between back pressure type waterstop blocks, to avoid the purpose of spillage, by keeping off
Fast lifting device is installed in plate, and top plate is installed in the output end of fast lifting device, top plate can be in fast lifting device
Top pressure inverted arch or back pressure type waterstop under effect of increasing, solving can make in existing tunnel construction because of the faulting of slab ends between waterstop
At in casting process, there is a situation where spillages, and expend that the time is long, of high cost, efficiency is low asks for the processing of the situation
Topic.
In order to solve the above technical problems, the technical solution adopted by the present invention is as follows：
