1、www.tahdmm.com振动式插板机对塑料排水板回带现象的处理www.sdjert.com振动式插板机对塑料排水板回带现象的处理 根据相关规范规定，严格检查塑料排水板的回带长度，当其超过50cm时，必须在相邻板位处补打一根，且回带的根数不宜超过打设总根数的5%。为有效减少塑料排水板回带，本文就对塑料排水板施工的“回带”现象进行探讨，谈些体会，供同行参考，不妥之处，敬祈斧正。Accordingtotherelevantregulations,strictinspectionofplasticdrainageplatebackbeltle

4、插板操作。插板机就可移位到下一个排水孔继续施打。在插设过程中,www.tahdmm.com振动式插板机对塑料排水板回带现象的处理www.sdjert.com可能会因为套管中进入淤泥,增大了塑料板与套管壁的摩擦力以致造成塑料板带出，这就是回带。排水板与管靴连接示意图见下图。塑料排水板穿过插板机的套管，从套管下端穿出，与专用管靴连接。Theconstructionsequenceofplasticdrainageboards:thelocationandtheplasticdrainageplatethroughthecatheterfromt
