4, front-back pull-push type or in pairs step type hydraulic pressure automatic shifting stand alternately, each circulation is supported once repeatedly to top board, destructible top board; be unfavorable for the supporting to top board; when roof condition is bad, supporting must be shut down, tunneling machine cutting and permanent support parallel operations can not be realized.
5, the monorail crane timbering machine of Germany's development.Can realize the mechanized operation of permanent support, avoid personnel to enter the operation of non-support district, but this device structure is too complicated, appearance and size is large, can only be applicable to large section roadway construction, and supporting and driving cut are at the same area, dry scratching, affects parallel operations efficiency mutually.
6, TBM rock ripper has worn-out open type, two shield, single shield etc., and tunnel construction temporary lining form is and the integrated support pattern of full section cut development machine.This support pattern boring head is to the integrated support of country rock, contraction, reach, support by shield total length to the support of top side again, repeatedly support destructible country rock, large, the large section of the radius of curvature that is only applicable to turn round, the good tunnel construction of wall rock condition, chance tomography, zone of fracture are easily stuck.
