Some standards for the construction of fire hydrant guardrail: precise lofting: to draw out the guardrail, draw its inner edge, fine tune according to the linearity, and ensure the guardrail is linear and smooth.
When setting out, for the straight line section, every 10 meters measuring a guardrail inside edge point, curve section should be determined according to actual calculation, ensure that its error shall not be greater than 4mm.
Reinforcement installation: the skeleton of the reinforcement is designed according to the requirements of the design, and it is connected with the pre embedded tendon on the top of the beam. When installing, the reinforcing steel bar shall be adjusted according to the drawing line of the setting out point to ensure the protective layer.
Template installation: the formwork shall be of integral steel mould, and the staggered table shall be strictly controlled when installing the formwork.
The formwork and the pavement joint are filled with sponge material to ensure the tight joint and no leakage. At the same time, the special release agent is adopted to ensure the uniform color and smooth surface of the concrete.
