What is the quota for mechanical backfilling?
In construction projects, mechanical backfilling is a common earthwork operation, and the determination of its quota is directly related to the accuracy of the project cost. This article will combine the hot topics and hot content on the Internet in the past 10 days, analyze the quota application rules of mechanical backfill in detail, and provide structured data tables to help readers quickly grasp the relevant points.
1. Quota classification of mechanical backfilling
Ratings for mechanical backfill are usually classified based on construction method, type of earthwork, and type of machinery. The following is a common quota classification table:
| Quota number | Project name | unit | Labor cost (yuan) | Material fee (yuan) | Machinery fee (yuan) |
|---|---|---|---|---|---|
| 1-1-10 | Mechanical backfill (loose fill) | m³ | 5.20 | 0.00 | 12.50 |
| 1-1-11 | Mechanical backfilling (rammed filling) | m³ | 6.80 | 0.00 | 15.30 |
| 1-1-12 | Mechanical backfilling of sand and gravel | m³ | 7.50 | 30.00 | 18.00 |
2. Application rules for mechanical backfill quotas
1.Construction method: Mechanical backfilling is divided into two methods: loose filling and tamped filling. Loose filling is suitable for general backfilling projects, while tamped filling is used for occasions requiring higher density.
2.Earthwork type: The quotas for different earthwork types (such as ordinary soil, gravel soil, etc.) are quite different, and the selection needs to be based on the actual project conditions.
3.Mechanical type: Commonly used backfill machinery includes bulldozers, excavators, road rollers, etc. The shift costs of different machinery are different and need to be specified in the quota.
3. Precautions for mechanical backfill quota
1.Engineering quantity calculation: The engineering volume of mechanical backfill is usually calculated based on the actual backfill volume, and the volume occupied by foundation, pipes, etc. needs to be deducted.
2.Regional differences: Quota standards may differ in different regions. Please refer to the latest quota issued by the local project cost management department.
3.construction conditions: In case of special construction conditions (such as high groundwater level, large backfill depth, etc.), the quota needs to be adjusted according to the actual situation.
4. The relationship between recent hot topics and mechanical backfill quotas
In the past 10 days, hot topics on the entire network regarding mechanical backfill quotas have mainly focused on the following aspects:
| hot topics | focus of discussion | Relevant quota number |
|---|---|---|
| green construction | How to reduce energy consumption of mechanical backfill | 1-1-10, 1-1-11 |
| Intelligent machinery | Quota application for driverless road rollers | 1-1-12 |
| BIM technology | Application of BIM in mechanical backfill engineering quantity calculation | 1-1-10, 1-1-11 |
5. Suggestions for optimizing mechanical backfill quotas
1.Reasonable selection of machinery: Based on the project scale and backfill requirements, select the most cost-effective mechanical combination.
2.Strengthen construction management: By optimizing the construction process, reduce machinery idle time and reduce shift costs.
3.Pay attention to policy trends: Keep abreast of the latest quota adjustment information to avoid cost deviations caused by quota changes.
Through the above analysis, I believe readers will have a clearer understanding of what quotas should be set for mechanical backfill. In actual projects, quotas need to be applied based on specific circumstances to ensure the accuracy and rationality of the project cost.
