The service time is 21 days, and the mechanical equipment lease fees are calculated according to the minimum lease time of 1 month: 3000 × 2+2100 × 2 is 10200 yuan.
2) Material cost:
the required amount of the polyurethane foaming agent is 3.14 × 0.007.007 0.007 × 0.007.007 0.007 × 0.26.26 0.26 × 13500-0.54 m3And the volume of the single bottle of foaming agent after expansion is about 1150ml, the demand is 0.54 × 1000 × 1000/1150-470, and the single price is 13 yuan/one, and the cost of the polyurethane foaming agent is 470 × 13-6110 yuan
The dosage of the repair mortar is 3.14 × 0.007 × 0.007 × 0.04 × 13500-0.083 m3. The dosage is less, and the cost is neglected.
3) Labor cost:
the labor cost of the hanging basket operators is 5200 yuan/month, the labor cost of repair workers is 280 yuan/day, the labor cost of general workers is 150 yuan/day, and the total labor cost is: 5200 × 2+280 × 4 × 21+150 × 2 × 21 ═ 40220 yuan.
Direct economic cost summation: 10200+6110+40220 is 56530 yuan.
If the template reinforcing device without the counter-pulling screw is adopted, the direct economic cost can be saved by about 56530 yuan.
