1、沿裂缝600mm宽开凿施工基面，除去结构板以上层次，查找裂缝，沿缝对楼板进行双面开凿30×30mm“V”型凹槽，并清理凹槽内砂土灰尘。
600mm wide cut along the crack construction base surface, removing structural panels above level, find cracks on the floor on both sides along the seam cut 30 × 30mm "V" shaped groove, the groove and clean sand dust.
2、清洗凹槽，采用速凝堵漏宝进行封闭凹槽，且按300～350mm预埋一道灌浆咀，灌注聚氨酯化学灌浆料作裂缝堵漏、粘合处理。
Cleaning grooves, using quick-setting plugging treasure will be closed groove, and press 300 ~ 350mm embedded a filling spout, filling polyurethane chemical grouting material for crack sealing,bonding treatment.
3、如结构出现承载力不足或收缩开裂过大，应进行粘贴钢板或碳纤维进行结构补强加固，批抹10mm厚水泥砂浆作找平层，并适宜掺入聚丙烯纤维作抗裂剂（也可铺设钢网）。
Bearing capacity of the structure appears as insufficient or excessive shrinkage cracking, should be pasted structural steel or carbon fiber reinforcement, awarded for wiping 10mm thick cement mortar leveling layer, and the incorporation of polypropylene fibers suitable for cracking agent (also laying steel network).
4、修复防水层次，其材料应采用与原有防水层次相协.
Repair water level, the material should be used with the original water level relative to the Association.
