Construction of seepproof screen in right mountain of TGP''''s shiplock and quality control

The seepproof screen in the mountain body to the right of the Three Gorges shiplocks is a permanent structure, and must meet high technical requirements, so that there were material difficulties in the construction. Since before the construction full preparatory work had been done and field productive tests had been conducted to have provided correct and reliable technical parameters and bases for its construction, and in the construction, effective quality control measures were adopted. The strict inspection and test after the completion of the seepproof screen showed that its technical and quality indexes all satisfy the requirement of design and specification. This paper presents the technical requirements, construction method, concrete mix proportion for the seepproof screen and the quality control and quality test in the construction process of the seepproof screen.
