四川省水利水电建筑工程预算定额的总说明（General description of budget quota for water conservancy and hydropower construction projects in Sichuan） General description of Sichuan Province Water Conservancy and hydropower construction engineering budget quota, General description One, Sichuan Province Water Conservancy and hydropower construction project budget quota (hereinafter referred to as the norm), divided into earthworks, rock engineering, masonry engineering, concrete engineering, template engineering, material engineering, gravel grouting and anchorage engineering, drilling engineering and other eight chapters. Two. This quota applies to the construction and expansion of medium-sized and small-sized water conservancy and hydropower projects in our province, which can be used as a reference for compiling the budget estimate, bidding tender price and bidding price of these projects. Three. This quota applies to projects at elevations less than or equal to 2000m. The elevation of the area above 2000m is calculated according to the elevation elevation of the site of the water control project and the prescribed adjustment coefficient. The elevation to the elevation of dam or sluice dam or sluice dam as the standard, not the bottom elevation as a water inlet. For the diversion type water conservancy and hydropower projects, such as the elevation difference between the head and the tail is greater than 500m, two different adjustment factors should be selected respectively. Table 1 adjustment coefficient of artificial and mechanical quota in plateau area Elevation 2000~2500 (m), manual adjustment 1.10, mechanical adjustment 1.25 Elevation 2500~3000 (m), manual adjustment 1.15, mechanical adjustment 1.35 Elevation 3000~3500 (m), manual adjustment 1.2, mechanical adjustment 1.45 Elevation 3500~4000 (m), manual adjustment 1.25, mechanical adjustment 1.55 Elevation 4000~4500 (m), manual adjustment 1.3, mechanical adjustment 1.65 Elevation 4500~5000 (m), manual adjustment 1.35, mechanical a
