1、沿裂縫600mm寬開鑿施工基面,除去結構板以上層次,查找裂縫,沿縫對樓板進行雙面開鑿30×30mm“V”型凹槽,并清理凹槽內砂土灰塵。
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,采用速凝堵漏寶進行封閉凹槽,且按300~350mm預埋一道灌漿咀,灌注聚氨酯化學灌漿料作裂縫堵漏、粘合處理。
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、如結構出現承載力不足或收縮開裂過大,應進行粘貼鋼板或碳纖維進行結構補強加固,批抹10mm厚水泥砂漿作找平層,并適宜摻入聚丙烯纖維作抗裂劑(也可鋪設鋼網)。
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、修復防水層次,其材料應采用與原有防水層次相協.
Repair water level, the material should be used with the original water level relative to the Association.
