Waterproof quality control method for electric power tunnel undercrossing riverway
The invention discloses a waterproof quality control method for an electric power tunnel undercrossing river channel, which comprises the following steps: S1, cofferdam preparation: obtaining the current water depth according to field actual measurement, adopting a soil cofferdam and soil woven bags for the cofferdam, setting the filling slope ratio of the soil cofferdam to be 1: 1, manually loading loose cohesive soil into the woven bags, stacking in a layered manner, setting the filling amount to be 1/2-2/3 of the bag capacity, sewing bag openings with fine flax threads or iron wires, and setting the filling slope ratio of the soil cofferdam to be 1: 1; during construction, the soil bag is flatly placed. According to the method, the power tunnel is an underground pipe network project penetrating through a river channel, and is suitable for waterproof quality control in a tunnel and culvert form and in a fresh water environment, and due to the unique environment, the method mainly takes the waterproof quality of the power tunnel as the core; the method mainly controls the concrete quality, the pouring mode, the pouring process, the maintenance means and the like of power tunnel main body construction, strictly requires the selection, the paving mode, the lap joint length, the protection measures and the like of the waterproof material, ensures the waterproof quality when the power tunnel passes through the river channel, and prevents the concrete from being in contact with the water environment for a long time.
本发明公开一种电力隧道下穿河道防水质量控制方法，包括：S1、围堰：根据现场实测实量得知目前水深，围堰采用土围堰加装土编织袋，土围堰填筑坡比为1：1，人工编织袋装松散粘性土分层叠加堆码，装填量为袋容量的1/2～2/3，袋口用细麻线或铁丝缝合，施工时将土袋平放。本方法电力隧道是下穿河道的地下管网工程，适用于隧道、涵洞形式且下穿淡水环境时的防水质量控制，因其独特的环境，所以该方法主要以电力隧道的防水质量为核心，对电力隧道主体施工的混凝土质量、浇筑方式、浇筑过程、养护手段等重点把控，对防水材料的选择、铺贴方式、搭接长度、保护措施等严格要求，确保电力隧道下穿河道时的防水质量，避免混凝土长期与水环境接触。
