6.2, afterwards, the chain (17) of leading in pulling bottle gouard moved by hands (18) overturns about 15 ° with wall mould base, and the rubber wheel (19) of auxiliary slipping mechanism is contacted with the vertical wall in tunnel, the formation sliding support,
After step 7, auxiliary slipping mechanism form sliding support, wall mould base is resolved into two split mould bases, respectively with the length remaining place propelling 1200cm of two split mould bases to basic mould bases; Remove the used basic mould bases in front (6) and base support (12), go to next circulation construction place in the place ahead and reinstall basic mould bases (6) and base support (12),
Step 8, two split mould bases after will moving connect into wall mould base again, afterwards 2～step 7 mid-board concrete the pouring construction that carries out next circulation repeatedly set by step.
