Technical field
The utility model relates to technical field of tunnel construction, in particular to a kind of tunnel fast lifting baffles.
Background technique
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
Sky sound, voids and pits, sand, dusting caused by native not full, concrete spillage etc., 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, the most fundamental problem is still spillage.
Spillage can not be mainly completely coincident 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 in casting process to that will form the faulting of slab ends that can not close up after mould between back pressure type waterstop,
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
Have the following problems in use process: 1, construction speed is slow, and in the actual construction process, preliminary bracing profiled may not be too round
Suitable, end head formwork width is different 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, large labor intensity, and every piece of wooden model securely must just can guarantee and not run the quick-fried mould of mould in reinforcing process, reinforce
Get up especially cumbersome；3, closed matereial cycle rate is low, and wooden model is cut when blocking according to section configuration, construction next time after demoulding
Utilization rate is quite low, causes wood consumption very big, increases construction cost.
