地下工程变形缝渗漏水的综合治理

Comprehensive Leakage Treatment of Deformation Joint of Underground Works

根据变形缝的结构构造特点,探讨了其渗漏水治理原则,介绍了多种注浆堵水方法,并为达到充分而长期的止水目的,提出了应增补的若干内防水措施,分析了这些措施在工程实践中的利弊、功效。指出:变形缝渗漏单靠注浆堵水,或者仅靠加设止水带之类措施,难以充分而长效,只有综合治理方可保证变形缝的止水功能。

According to the structrual features of the deformation joint, the principle of leakage treatment and a variety of grouting and blocking water methods are introduced, The paper also provid supplemental waterproofing measures with the intention of sufficient and long-term water stopping and analyses the advantages and disadvantages of the measures as well as their effects. It points out it is difficult to ensure the wateproofing when dealing with the leakage of the deformation joint only by grouting and blocking water or waterstop and the like. It is only comprehensive treatment solutions that can assure the water stopping of the deformation joint.
