In water conservancy engineering, 3:7 ash backfilling is a commonly used foundation treatment method, which is favored for its good compaction and stability. In 2024, the unit price analysis of 3:7 ash backfill includes the following aspects:
1. **Material Costs**:
- The price of ash materials: The market price in 2024 will be about 30-60 yuan per cubic meter, depending on the quality of the material and the distance of transportation.
2. **Labor Costs**:
- Construction worker salary: In 2024, the daily wage of construction workers will be about 200-300 yuan, which may vary depending on the region and construction difficulty.
- Management fee: The daily salary of project management personnel is about 300-500 yuan.
3. **Construction Machinery and Equipment**:
- Machinery and equipment rental: including excavators, rollers, etc., the cost is about 10-20 yuan per cubic meter.
4. **Construction area or volume**:
- Volume calculation: Calculated according to the actual construction volume, the price is determined according to the volume size.
5. **Other Expenses**:
- Foundation treatment: including excavation, leveling, etc., the cost is about 20-30 yuan per cubic meter.
- Quality inspection: In order to ensure the quality of the project, it may be necessary to carry out quality inspection, and the cost is about 5-10 yuan per cubic meter.
Based on the above unit prices, a rough unit price analysis can be obtained. For example, if the construction volume is 1,000 cubic meters, the cost of ash materials is 50 yuan per cubic meter, the labor cost is 1,000 yuan per day, the construction period is 10 days, and the machinery and equipment rental cost is 15 yuan per cubic meter, then the total material cost is 50,000 yuan, the total labor cost is 10,000 yuan, the total machinery and equipment rental cost is 15,000 yuan, and the total cost is 75,000 yuan. This does not include other possible expenses.
Note that this is just a simplified estimate. Actual costs may vary depending on region, supplier, difficulty of construction, and other factors. It is advisable to consult with a professional hydraulic engineering 3:7 ash backfill supplier or construction team for a detailed quotation before making a final decision.
