The maintenance work of the core vibration concrete pipe process is also very important, especially for the early maintenance work after tube forming.The dry-hard concrete used has less water and poor fluidity. When the control is not good, it is easy to cause water loss and dryness, and the compactness is poor. The concrete is prone to honeycombs, holes and ring cracks, which will seriously affect the overall concrete strength.
At present, most of the application methods are covered by steaming oxygen cover, and different solar terms can be appropriately changed.For example, summer can be natural or steam curing, and in winter, steam curing can be used.It is worth paying special attention to the maintenance time with the positioning ring. Nowadays, in order to speed up the rotation of the positioning ring, many manufacturers will take off quickly, so that the positioning effect will not be achieved, and the deformation of the tube is large.
For dry hard concrete, it can also be said that it is a mold release bare product, maintenance work is particularly important, and the corresponding control technology should be adopted according to the season and weather conditions.In the summer, watering and moisturizing can be timely, and heat storage in winter can be used to ensure the temperature and humidity of the product.
