Road fence installation method

Road fence installation method

 

Installation method and sequence of highway guardrail network: The three-dimensional crossover operation of the guardrail network installation engineering space is more complicated, and there are more cooperations in various types of work. Therefore, in the installation, perfect technical measures should be formulated to control the whole process of construction and establish complete quality assurance. The system and safety assurance system enable the project to be implemented smoothly in a safe and orderly manner.

The installation of engineering fence nets, steel beams, platform beams and purlins is carried out by means of sub-assembly hoisting method: one is to hoist the guardrail net in turn; the other is to hoist the inter-column support; the third is to the roof beam, horizontal support and contact beam Lifting; fourth is lifting the platform. The installation sequence is: guardrail net - inter-column support, roof beam, contact beam, horizontal support beam - two-story platform beam, purlin, pull strip, corner truss.

 

Road fence network installation technical solution foundation Before preparing to install the fence network, it is necessary to have the civil construction process handover (including written materials and physical objects), and then re-test each positioning size, shaft position, bolt center line, elevation, etc.

 

Retested content: Whether the measured data of the base top elevation meets the design requirements. Whether each span and column spacing meet the design requirements and acceptance specifications. Whether the information is complete and whether it is consistent with the actual measured data on site. Before installing the fence mesh, it is necessary to remove the concrete ash and set up the basic positioning line. The exact "+" axis should be clearly marked with red paint to ensure that it matches the axis of the fence.

 

The height of the net is adjusted, and the horn is used. The thickness of the horn is calculated according to the measured elevation. First, a corner is used, and the level is used for measurement. Then the other three corners are adjusted by the level, but note that each angle horn does not exceed three. Piece.
