① Use concrete ground hardener to improve the wear resistance of ramp surface;

(2) a rubber ring positioning template with an anti-slip groove is adopted to place the rubber ring,

Therefore, the construction efficiency and the accuracy of the anti-skid groove position are greatly improved.

Second, the underground garage ramp wear-resistant floor process operation points are as follows:

( 1)

Clean up the grassroots.

(2)

Firstly, setting a concrete kerb elevation control line,

Then paving the kerb with C30 concrete,

The clearance between road teeth is controlled at about 65438+/-0.5mm,

Use 1

2 filled with cement mortar. After the concrete for paving kerbs and setting cement slurry reaches a certain strength,

Then the concrete elevation control line and anti-slip ring position line of the ramp surface layer will pop up on the kerb.

(3)

Internal structure of concrete for binding inclined plane of steel bar

Double-layer bidirectional steel bar,

The lower reinforcement should be padded with mortar and bound firmly.

Set between two layers of steel bars.

Horse stool tendon,

Spacing 600 ~

900 mm

,

Arrange in a plum blossom shape.

(4)

Construction joints shall be reserved for the surface concrete of the ramp, and it shall be poured in sections.

Every 20 meters

Leave 1 construction joint.

(5)

The concrete strength grade of the concrete pouring surface is C30,

Stone size 5 ~

20 mm

,

Slump control in 10 ~

14cm. When pouring concrete, tamp it with vibrator.

Leveling with a long ruler,

Rub it flat with a wooden trowel and lift the pulp. (6)

After the hardener is spread on the concrete for 1 time, it will be spread after leveling, slurry lifting and before initial setting.

The dose is the total amount.

Two thirds of the people,

Diffusion should be uniform,

Sweep the uneven place evenly with a broom.

(7)

Firstly, fix that positioning template of the rub ring of the anti-skid groove according to the position of the elastic line on the kerb,

Then the rubber rings of the anti-skid grooves are pressed into the concrete in turn through the reserved holes on the template,

Aft that rubber re fills the reserved holes of the template,

Take out the template,

Move to the next paragraph for use.

(8)

The amount of hardener used for the second coating is 2/3 of the total amount.

,

After the hardener absorbs water completely, rub it flat and compact it with a wooden trowel.

Then calendering and pulping with an iron trowel for three times,

Finally, brush the concrete surface with a plastic broom.

(9)

Rubber ring should be taken out before the final set of concrete, so that the concrete will not collapse or fall off.

( 10)

Concrete curing 12h

After that,

Brush curing agent on its surface,

The curing time is not less than 7d. During the maintenance period, railings should be set to close,

And assign a special person to be on duty. It is forbidden to get here or take a bus.
