Waterproof Engineering Chapter VIII Construction Cases and Technical Measures, Construction Survey 2. Earthwork reinforcement shall be processed and produced at the site according to the design requirements of drawings. Before the tower crane is hoisted to the construction section, be familiar with the drawings. Regardless of whether the grade, diameter, shape, size and quantity of semi-finished steel bars conform to the material card, the installation positioning line of steel bars should be corrected and supplemented, and the specification, shape, size and quantity of steel bars should be indicated at the binding position. Scrub the concrete surface with a wire brush at the construction joint position 1. The steel bar connection ensures the construction quality. In this project, electroslag pressure welding is proposed for the vertical steel bar connection in the column with a diameter of 20 mm, and binding and lap welding are proposed for the vertical steel bar connection in the column. The diameter of the reinforced bar in the beam is equal to or greater than 18 mm, and the rest of the reinforced bar with the diameter of 18mm is planned to be connected by flash welding or one-sided lap welding. The formwork project is a teaching building with a height of 4.2 meters on the first floor and a height of 3.6 meters on the second floor. Due to the high first floor, the construction difficulty of dense steel bars must be paid enough attention. The case of formwork support is only the difficulty of formwork engineering.
