Slope Protection Concrete Pouring Technique !
Показать описание
Construction technology of slope protection concrete pouring is as Follows :
I. Construction Preparation
1. Material Preparation :
- Cement
Select cement varieties that meet the design requirements !
- Sand And Gravel
Well-graded sand and stones !
- Admixtures
Add an appropriate amount of admixtures such as water reducing agent and early strength agent as needed !
2. Equipment Preparation :
- Concrete mixer and transportation vehicles !
- Vibration equipment such as insertion vibrator and plate vibrator !
- Formwork and support system !
3. Preparation Of Working Conditions :
- The slope protection foundation has been accepted as qualified, and the base is cleaned up !
- Survey and setting out to determine the position and elevation of the slope Protection !
- The formwork is installed firmly with tight joints !
II. Concrete Mixing
1. Prepare materials according to the design mix ratio and strictly control the water-cement ratio !
2. The mixing time should comply with the regulations to ensure that the concrete is evenly mixed !
III. Concrete Transportation
1. Use concrete transportation vehicles to transport the concrete to the construction site in time !
2. During transportation, prevent concrete segregation and slurry leakage !
IV. Concrete Pouring
1. Before pouring, inspect the formwork, steel bars and embedded parts to ensure their accurate positions and firmness !
2. The concrete should be poured in layers, and the thickness of each layer should not exceed 300mm !
3. Use insertion vibrators for vibration.When vibrating, insert quickly and pull out slowly, with evenly distributed insertion points and move point by point without omission !
4. Vibrate until the concrete surface is bleeding and there are no bubbles !
5. During the pouring process, pay attention to maintaining the continuity of the concrete to avoid cold joints !
V. Concrete Curing
1. After the concrete is poured, curing should be carried out in time !
2. Curing methods can include covering with plastic film, watering, etc. to keep the concrete surface moist !
3. The curing time should be not less than 7 days !
VI. Formwork Removal
1. When the concrete strength reaches the design requirements, the formwork can be removed !
2. When removing the formwork, operate carefully to avoid damaging the concrete surface !
The above is the main content of the construction technology of slope protection concrete pouring. In actual construction, operations should be carried out in strict accordance with design requirements and relevant specifications to ensure construction quality !
