And have various protection measures. 3.5 The equipment can be installed after the steel reinforcement foundation has been accepted and the pressure test report has been submitted. 3. The main parts should be installed during the construction period. Technical guidance: 4 Technical requirements for installation
4.1 Before lifting the steel support, the foundation should be inspected and the small flat dimensions of the vertical, horizontal and diagonal forces and the elevation of the base should be measured. The standard is +3m. If the coordinates of the middle support are out of tolerance, steel plates can be used to pad them. All parts must be installed before installation. According to the drawings, if deformation and dimensional changes are found during transportation, loading and unloading, and maintenance, plastic and correction should be made.
.2 The small deviation of the water level of the bearing point in the fruit position is +3m, and the tolerance of the water level in the direction of the bearing point is m. It should be reversed, and then the support parts should be installed.
4.3 Support bearing and bottom joint
4.3.1 The difference between the installation and elevation of the bearing is =3mml, 4.3.2 After the bottom frame is installed, its diagonal load dimensional deviation should meet the requirements of Example 1. Approved by the Ministry of Machinery Industry on January 15, 1997, implemented in 198011, JR/T 8536- 1997, and are one electric field and two electric fields respectively. 4.3.3 The empty diagonal tolerance of the ash hopper is ±8m. 4.4 Tiger parts, two electric fields, and five electric field bottom cases are installed after the negative line size is stored. National 1, 4.4.1 The beams and related parts in the competition body must be inspected and the corresponding ten Ning center lines must be marked. 4.4.2 The tolerance value of the shell after basking shall be checked according to the drawing requirements. The whole shell is welded in parallel. The quality of wet joints shall meet the requirements of Table 1. All positioning and penetration of the shell shall be welded in reverse order after tightening, and the sealing performance of the joint shall be tested by the tearing method. 4.4.3 The center value of the joint between the main beam and the center of the bottom beam is 25mm. 4.4.4 The joint gap between the bottom of the main beam and the upper surface of the vertical beam should not be more than -2mm. 4.4.5
When falling, install the positioning device. The center line size of the two positioning measures is adjusted to ±1am. After the attached plates are installed, they are hoisted around the table 1
