In modern civil engineering, shotcrete slope protection is a common slope protection measure, which strengthens and protects the slope by shotcrete to prevent soil erosion and slope collapse. The following is a detailed analysis of the cost of shotcrete slope protection according to the market situation in 2024, and listed one by one according to the various expenses, and finally a brief summary.
1. Labor costs:
1. Shotcrete slope protection: 30 yuan/㎡
This fee covers all workers' wages and related labor protection costs for operating the spraying equipment for concrete spraying.
2. Hanging steel mesh: 2.61 yuan/㎡
The hanging of the steel mesh requires a certain amount of labor, and the weight of the steel bar required per square meter is about 2.9 kg, and the labor cost is 2.61 yuan/㎡ according to the price of 0.9 yuan/kg.
2. Material costs:
1. C20混凝土：27.54元/㎡
C20 concrete is a commonly used shotcrete material, the volume of concrete required per square meter of slope protection is about 0.09 cubic meters, considering the loss rate of 2%, the actual amount is 0.09 cubic meters multiplied by 1.02, and then multiplied by the unit price of 300 yuan/cubic meter, the material cost is 27.54 yuan/㎡.
2. Reinforcement mesh (round steel): 8.91 yuan/㎡
The reinforcement mesh is used to increase the tensile strength of concrete, and the weight of the reinforcement mesh required per square meter of slope protection is about 2.3 kg, which is calculated according to the price of 3.8 yuan/kg, and the loss rate of 2% is also considered, and the material cost is 8.91 yuan/㎡.
3. Fixed steel bar (rebar): 1.84 yuan/㎡
The fixed steel bar is used to fix the steel mesh on the slope, and the weight of the rebar required for slope protection per square meter is about 0.5 kg, which is calculated according to the price of 3.6 yuan/kg, plus the loss rate of 2%, and the material cost is 1.84 yuan/㎡.
3. Management fee (5%): 3.55 yuan/㎡
The management fee is an estimate of the overall project management cost, calculated at 5% of the total cost.
4. Profit (10%): 7.09 yuan/㎡
Profit is the amount of revenue that the contractor expects from the project and is calculated at 10% of the total cost.
5. Quotation (9% including tax): 88.87 yuan/㎡
The quote is the final price after taking into account all costs and expected profits, plus 9% tax.
To sum up, the total cost of shotcrete slope protection in 2024 is quoted as:
- Labor cost: 32.61 yuan/㎡ (shotcrete slope protection + hanging reinforcement mesh)
- 材料费：38.29元/㎡（C20混凝土 + 钢筋网片 + 固定钢筋）
- Management fee: 3.55 RMB/㎡
- Profit: 7.09 yuan/㎡
- Quotation (tax included): 88.87 yuan/㎡
Brief summary:
The cost of shotcrete slope protection in 2024 is mainly composed of labor costs and material costs, of which labor costs account for a relatively large proportion. Management fees and profits are integral to the operation of a project, while taxes are a statutory financial burden. When formulating quotations, it is necessary to comprehensively consider the market fluctuations of various costs to ensure the economic benefits and market competitiveness of the project.
