Technical preparation 1, the construction site manager: project managers, technicians, quality inspector, safety officer, custodian, surveyors have been stationed in the field wear wholesale cast stone, "Stone one level" is ready 2 study engineering characteristics of the preparation construction design, construction methods to determine the practical. 3, for all construction staff technical clarification rolling microcrystalline cast stone, allowed to understand the basic situation of the project. 4, related to this project were collected Atlas, specifications, work instructions. 5, calculate the amount of the sub-projects to provide basic data for budgeting and guiding production. Operation ①, concrete inner wall of the funnel to clean hand hammer will be higher than the concrete surface then pull rods, PVC casing all clean microcrystalline cast stone linings, use a wire brush to clean the surface when pouring the concrete floor of the pulp, clean up after use Brush the surface dust cleared ensure concrete surface is smooth and no topsoil. ②, buried around the mouth end of the funnel member clean out the 30 × 3 welded to the bottom of the mouth angle, angle steel and embedded parts of the welding connection must be fully welded.
