Execution Method for Spillway Hydraulic Surfaces: Upper Gotvand Dam

A. Zabihollah Zadeh and M. Yamin Pour

Abstract—Upper Gotvand Dam the largest rock fill dam of Iran is involved with several massive affiliated projects. 72m wide Spillway structure is 570m long from ogee to flip bucket with 4 radial gates, installed on ogee structure. 800000 m3 concrete is demanded to fulfill project most of which is required for hydraulic surfaces. Numbers of methods to accomplish various hydraulic surfaces are including screed pipe and manual trowelling, moving bar, and slip-form application. Facing technical as well as executive obstacles have brought out of several worthwhile conclusions. For instance, face has to be controlled in near edge for adjacent concrete before screed or mold installation. Conformity to proper executive sequences such as preparation, tool box installation, locating installation place for CJ molds, and then reinforcement has to be considered. Fulfilled surfaces have to be protected of either impact or any pollutants. Errors have to identify through comparison of surveys for performed surfaces with that of templates before placement, and then should be corrected in conjunction with adjacent blocks or next lifts. And to impede bolt displacement or shear occurrence, first hydraulic lift has to be casted using molds with no consoles.

Index Terms—Ogee and chute slabs, screed pipe and bar, slip-form, trowel operation.
