Abstract: The flow surface of the spillway in the hydrological electricity project will be subjected to high water flow rate and requires high resistance to the surface wearing of the concrete lining structures. This paper presents and construction technique of the pouring of the concrete lining structure of Houziyan Hydrological Electricity Project. The permeable form cloth was used inside the mobile steel forms and the concrete was cured with different additives. The work verified that the application of the permeable form cloth and the concrete additives in the poring of the wearing surfaces of the hydrological structures.

Key words: High Flow Rates, Hydrological Tunnels, Concrete； Permeable Form Cloths； Concrete Additives
