Welded anchor bolt road and bridge guardrail embedded parts with legs welded stool steel plate

  Process according to the drawing → Measurement and positioning → Support → Place bolts, embedded parts and temporary fixing → The technician shall be familiar with the drawings and carry out the technical disclosure of measurement after re measurement and fixing the measurement positioning
However, a full-time surveyor shall lead out the control line and elevation control line of embedded parts and bolts from the measurement control network according to the technical measurement requirements
Then determine the specific location according to the center and elevation of the designed embedded anchor bolts and embedded parts
The fixed support shall be cast with a relative elevation point on the fixed support pile, and the bottom shall be reliably welded, completely separated from the formwork fixed frame, reinforcement fixed frame, etc
, and ensure that the fixed frame shall have sufficient stiffness and stability
After the bolt fixing frame is erected, the bolt installation should first fix the center according to the positioning line, then adjust the elevation, and carry out temporary reinforcement according to the scheme requirements
After re measurement, after the fixing bolts and embedded parts are placed, the surveyor shall adjust and check the bolts and embedded parts again
After the inspection meets the specification requirements, the lower part of the bolts and the fixed frame shall be firmly welded and fixed
At the same time, the bolt fixing frame shall be welded in both vertical and horizontal directions to strengthen the diagonal bracing
