Rubber Fender Installation and Construction Technology

1,Measurement Positioning

The personnel release the relevant dimension line of the D300 positioning plate.When drilling the D300 fender,the machined positioning plate should be fixed with expansion bolts according to the relevant dimensions.

2,Drilling

Electric core drills,air compressors,glue injectors,special round brushes,greasy knives,and necessary protective equipment,such as gloves,masks,etc.,are all necessary for drilling and planting ribs.According to the requirements of the project,choose the drill rod of the corresponding specification.The length of the drill rod should be able to meet the drilling design depth requirements.When do you want to avoid the position of the steel bar in the base material,mark the drilling position,the drilling position should be correct,the hole spacing should be in accordance with the regulations and design requirements,the channel should be dry,otherwise manual drying should be carried out to ensure that the fender bolts and concrete stick It should be absolutely dry before curing.

3,Cleaning Hole

After the hole is formed,the hole must be cleaned with an air compressor and a special round brush to remove the dust in the hole to avoid the isolation of the dust and affect the bonding surface.First use an air compressor to blow up,and then use a brush to clean the channels until there is no dust.

4,Cleaning Hole

Use a brush moistened with acetone to clean the peripheral wall of the concrete tunnel to ensure good adhesion between the substrate hole wall and the structural adhesive.After the acetone volatilizes,put a paper stopper on the tunnel opening in time to avoid contamination and set it aside.

5,Adjust Glue

The best construction temperature of structural adhesive is 15℃~25℃.According to the change of construction temperature,the amount of curing agent can be appropriately increased or decreased through experiments.Precise measuring instruments should be used for the glue preparation,such as balances and platform scales less than 5kg.The glue is first called the glue and then the curing agent.After the two-component resin glue is weighed and mixed,it should be stirred vigorously,and the dosage should not be too much at one time,so as to avoid the long time and the deterioration of the viscose,which will affect the bonding quality of the construction.Generally,the structural glue prepared at a time should be within 30min-40min All used up

6,Hole Injection Glue

According to the application form of the anchoring glue(tube type,mechanical injection type,on-site preparation type as above)and direction(up,down,horizontal),adopt the corresponding injection method.Glue injection can be used to fill the pores with a viscose infusion device or other methods.Be sure to fill the pores and remove air so that the gel occupies more than 80%of the pore volume.

7,Planting Screw

After filling the structural glue,immediately implant the screw,and rotate the screw appropriately to expel the air between the glue and the screw,and evenly combine the colloid.Clean up the excess structural glue in the orifice,and set up a temporary support for the longer screw before the anchor is solidified to prevent displacement;the completed screw should be statically cured for Id~3d,and disturbance is prohibited during curing.
