针对地下室无地下压力水浸渗之忧的特点,用主体灌浆砌筑技术提高主体的质量和密实度,增加主体结构的防水能力,减少渗漏概率,用纤维防水复合砂浆多层抹灰防水技术做抗渗防潮层,辅以外围护结构槽边和板底夯填3∶7灰土层作避水层,以此来防止地表滞留水对结构的侵扰。使三方共同工 In view of the characteristics of underground water pressure without underground pressure infiltration, the main grouting technology can improve the quality and density of the main body, increase the waterproofing ability of the main structure and reduce the leakage probability, and use the multi-layer waterproofing technology of fiber waterproof composite mortar Do impermeable moisture barrier, supplemented by the outer edge of the retaining structure and the bottom of the bottom ram filling 3: 7 ash layer as a water-repellent layer, in order to prevent surface water retention on the structure of the disturbance. To work together three parties
