按照API686要求，地脚螺栓一般有土建单位在浇筑基础时使用定位模板进

According to API686 requirements, anchor bolts are generally pre-embedded by civil engineering units using positioning templates when pouring foundations. Qi'an is responsible for retesting of foundation bolts and anchor bolts. <br>Some of the equipment in this project needs to be pre-embedded with on-site anchor bolts. During embedding, the equipment installation bottom plate must be placed on the equipment foundation with temporary shim. After confirming the axis and installation elevation, insert the anchor screws through the equipment bolt holes. Install the double nuts, the exposed part is subject to the 2~3 teeth of the anchor bolt thread, any part of the anchor bolt is at least 15mm away from the reserved hole wall. <br>Floor leveling <br>The elevations of all base plates must conform to the data in the construction drawings. <br>The floor level is checked with a bar or frame level with an accuracy of 0.02mm. <br>For the bottom plate manufactured according to the API standard, the horizontality of the bottom plate must be within 0.2mm/m in the vertical and horizontal directions, and the bottom plate of the pump manufactured according to other standards is 0.4mm. <br>Base plate elevation, axis, horizontality deviation: <br>allowable deviation <br>plane position <br>horizontal degree vertical and <br>horizontal when there is no mechanical contact with other equipment ± 5 mm (API standard) when there is mechanical contact with other equipment The bottom plate grouting There are two types of grouting in this project . One is epoxy grout and the other is ordinary grout. Epoxy grouting template preparation All templates must be made of materials with sufficient strength. The inner surface of all formwork should be coated with three layers of wax to prevent adhesion by grouting. The formwork has 25 mm (1 inch), 45° chamfered slats at all vertical corners and the horizontal surface of the grout. The template should be properly sealed to prevent the leakage of grout.
