Nowadays, the labor cost is increasing, and the state attaches great importance to environmental protection. It has become an inevitable trend to replace manual spreading with powder spreader. What is the better use of spreader than manual operation? How much can the construction cost be reduced? Let's talk about it.
What are the advantages of powder spreader than manual spreader?
Taking 20 cm thick concrete in situ cold recycling as an example, the concrete consumption is 5%, about 5000 square meters is recycled, and the daily concrete consumption is 115 tons. The cost comparison is as follows:
Manual paving: 3000, 25 people, 120 salary, 200 diesel engine fee, 400 tractor, 36800 concrete cost, etc., and the final total cost is 40400. Powder spreader: Labor 200, concrete 34500, diesel engine cost 240, final total cost 34940.
This calculation assumes that the concrete consumption is the same and the efficiency is the same. In fact, in the actual application process, the powder spreader will have the following two advantages:
1. In general, the concrete consumption can be reduced by 0.5% compared with manual spraying, that is to say, when using manual spraying, the actual control consumption of concrete should be increased by 1% compared with the theoretical mixing amount, while the control amount with machine equipment can be increased by 0.5%;
2. The spraying efficiency of machinery and equipment is higher than that of labor. The total area of spraying per hour is 4000 square meters, which can supply 5 sets of cold regeneration at the same time. Due to the improvement of efficiency, the cost of mechanical equipment and labor in the unit area will be greatly reduced to save costs for customers.
The above is the analysis of the advantages of powder spreader compared with manual spreader. I believe everyone can see the advantages of spreader.
