（3）The construction of basement raft board post poured band uses the pattern of advanced water-stopping；
（4）Post-cast strip Side shuttering is fixed on soldered ladder muscle using steel wire, and with making reliable in baseplate reinforcing bar
Connection, ladder muscle and post-cast strip side are installed using fast easy-to-closing in net stencil, and wherein steel wire is 10 mesh steel wires, or using double
Layer steel wire, ladder muscle uses the reinforcing bars of Φ 14, and bottom plate is beam, wall, plate.
3rd, the construction of outer wall of basement construction of guide wall seam, comprises the following steps：
（1）Because step 2-3 is poured, to smash the difference time longer, many debris and dust fine sand is retained on surface, if cleaning is not clean
As separation layer, as penetrating passage, therefore it must be rinsed well before pouring with water；
（2）40 thick 1：Concrete is poured in 1 cement mortar.
4th, without waterproof requirement after-pouring band beam-slab, comprise the following steps：
（1）Fast-easy closing-up net is used for template without waterproof requirement post-cast strip beam；
（2）Post-cast strip is supported post-cast strip top plate position in top plate position shuttering supporting using double bowl buckle frame.
Beneficial effects of the present invention：Using post-cast strip advance water stop construction method, economic benefit harvest is obvious, and to whole
The influence that duration is brought compares, and can save the duration 25 days or so, and construction costs can reduce by 950,000, and with to personnel's work holdup
Influence compares, and the enthusiasm of workman's work can be improved, beneficial to the stabilization of personnel.
