6. The edge (flat) stones, tree pools and other projects of road engineering are calculated in linear meters, including the arc length of each corner.

Third, the road surface?

1. The quantities of asphalt concrete, cement concrete and other pavements in road engineering shall be calculated by multiplying the design length by the actual paving area of widened parts such as design width and circular arc, and the area occupied by various wells within 1.5m2 shall not be deducted. ?

2. The expansion joint is calculated according to the design expansion joint length × expansion joint depth by area, and the joint is sawed with a saw.

Calculate the length in meters. ?

3. The pavement surface layer shall be calculated in square meters according to the area shown in the design drawings (the surface layer with flat stones shall be deducted from the flat stone area). ?

Sidewalks and other things?

The pavement area of sidewalk blocks is calculated according to the actual pavement area.

Fourth, traffic management facilities?

1. Production of signs, posts, portal frames and sporadic components

(1) sign production is calculated in square meters according to different shapes;

(2) Benchmarks are calculated in tons according to different rod types;

(3) The portal frame is manufactured in tons;

(4) calculating patterns and characters according to the maximum peripheral area;

(5) Double-column poles are calculated in tons.

2. Installation of signs, columns and doorframes?

(1) Installation of traffic sign poles, in which single column poles and single cantilever poles (L poles) are calculated according to different pole heights, and others are measured according to different pole types, including fasteners for signs;

(2) The installation of portal frame is calculated according to different spans; ?

(3) The installation of circular, triangular and rectangular sign boards shall be calculated by the number of blocks according to the area of different boards; ?

(4) The inducer is only installed and calculated;

(5) The installation of reflective protective columns shall be calculated by quantity.

3. Pavement marking?

(1) The marking loss has been included in the subtitle, and the quantities are measured in square meters according to the drawn area.

Calculation; ?

(2) The patterns and characters in special-shaped sign lines are calculated in square meters according to the maximum peripheral rectangular area of a single sign, and the colored areas of diamonds, triangles and arrows are calculated in square meters according to the paint.

4. Isolation facilities?

(1) The production of isolation guardrail is calculated in tons; ?

(2) The installation length of road isolation guardrail is calculated according to the design length, and the height of guardrail is within 1.2m, and the interval within 20㎝ is not deducted; ?

(3) The corrugated steel guardrail includes two parts: corrugated steel beam and column, and the bolts are included in the subtitle, so the weight of the main material does not include the connecting bolts, but includes fittings such as anti-blocking blocks (weight belongs to corrugated steel plate) and I-shaped steel beams (weight belongs to column); ?

(4) When calculating the weight of the steel column of the isolation grid, diagonal braces and other components should be included; ?

(5) When adding a steel frame on the metal mesh surface, the material consumption of the steel frame shall be calculated separately, but the labor and other materials shall not be adjusted. 5. Demolition of traffic facilities?

The demolition of traffic facilities shall be calculated according to the unit of measurement of the corresponding project.

5. Workshop railway?

1. Division of the junction between workshop railway and factory railway:?

(1) When the paving methods are different, the boundary should be the junction of different paving methods.

(2) When the laying method is the same, it is bounded by the outer edge of the ramp at the door of the workshop.

2. The workshop railway is calculated according to the actual laying length.

3. The wheel guard rail shall be calculated according to the length of single-sided paving. ?

4. Sinking renovation refers to the process that must be carried out after the trial operation of heavy rail, no matter how much it sinks, it must be calculated. The quantity of settlement renovation can be track-laying quantity, and the settlement renovation should also be calculated if the light rail needs to test the track when running a small train. The quantity is multiplied by the coefficient of 0.6 according to the corresponding project quota of heavy rail. ?

5. grade crossing should be paved in linear meters. ?

6. The ground between the workshop and the railway is calculated according to the corresponding project of floor division.

7. Laying turnouts shall be calculated according to each group. ?

8. Ballast shall be calculated in cubic meters according to the design, and the volume occupied by sleepers shall be deducted.
