江西峡江水利枢纽进水口检修闸门门槽二期混凝土渗漏治理

Leakage Treatment of the Second Phase Concrete Work of Water Inlet Bulkhead Gate Slot of Xiajiang Hydro-junction in Jiangxi

采用在门槽混凝土下游侧钻孔引流,将其表面封闭后进行聚氨酯灌浆材料封堵施工的方案,对江西峡江水利枢纽进水口检修闸门门槽二期混凝土进行渗漏治理,结果表明该施工方案防水效果良好,值得同类混凝土渗漏治理借鉴。

For the leakage treatment of the second phase concrete of the water inlet bulkhead gate slot of Xiajiang Hydro- junction project, first the downstream sides of the gate slot concrete was drilled for drainage; then polyurethane grout plugging was carried out after its surface was sealed. It turned out the waterproofing effect was good, and it was worth considering for similar concrete leakages treatments.
