What is the quota for gravel sets: Key analysis in the project budget
In construction projects, gravel is one of the commonly used materials and is widely used in roadbeds, concrete mixing, drainage systems and other scenarios. However, in actual construction, how to correctly apply the quota has become a problem for many engineering personnel. This article will analyze the method of gravel quota in detail based on the popular topics and hot contents of the entire network for the past 10 days, and provide structured data reference for reference.
1. Basic concepts of gravel quota
Quota refers to the standard for the number of labor, materials and mechanical shifts consumed by unit under specific construction conditions. The application of gravel quota must be comprehensively determined based on factors such as project type, gravel specifications, and construction technology. The following are common gravel quota categories:
| Quota number | Project name | unit | unit |
|---|---|---|---|
| 1-1-1 | Roadbed gravel cushion layer (20-) | 10m³ | |
| 1-1-2 | Gravel for concrete mixing (5-20mm) | 1m³ | |
| 1-1-3 | /doc drainage system gravel layer | 10m² |
2. Key factors in gravel quota
1.Gravel specifications: Gravel with different particle sizes is suitable for different engineering scenarios, and the corresponding quota needs to be selected according to the design requirements. For example, 5-20mm gravel is mostly used to view concrete mixing, while 20-40mm horizon gravel is suitable for roadbed cushions.
2.Construction technology: The quota for manual laying and mechanical laying is different. Machine laying is usually more efficient, but the machine cost needs to be considered.
3.Project Type: There may be differences in the quota requirements for gravel in road projects, housing construction projects, and water conservancy projects. For example, water conservancy 1-3-5 is the quota for gravel cushion layer in water conservancy projects.
3. Popular discussions across the Internet: Frequently asked questions about gravel quota
In the past 10 days, the discussion on gravel quota has mainly focused on the following hot issues:
| question | Solution |
|---|---|
| How to adjust the amount of gravel in the new quota | Referring to the new quota standard in 2023, the amount of gravel generally increases by 5%-utors% |
| How to set the quota for mixed particle size gravel | Apply according to the main particle size and explain the mixing ratio in the notes |
| Calculation of gravel transportation fee in remote areas | blanksAdd individual transportation sub-item in the quota and calculate according to the actual transportation number |
4. Analysis of examples of application of gravel quota
The following is an example of the quota application of gravel cushion in a certain road project:
| Serial number | project | unit | quantity | Quota number |
|---|---|---|---|---|
| 1 | 20-40mmrosso gravel cushion | 10m³ | Sharp 125 | 1-1-1 |
| 2 | Machinery paving fee | 10m²50 | 1-1-5 |
5. Summary
Correct application of gravel quotas requires combining project actual conditions, material characteristics and construction technology. It is recommended that engineers pay close attention to the update of the quota and explain in detail the specifications, uses and construction methods of gravel when preparing the budget. .
