Construction Technology of Cement Concrete Slipform Paver

Construction Technology of Cement Concrete Slipform Paver

1、 Construction preparation

Before carrying out the construction of the cement concrete slipform paver, sufficient construction preparation work is required. This includes understanding project requirements, determining construction plans, preparing relevant materials and equipment, etc. At the same time, it is necessary to clean and level the construction site to ensure smooth progress.

2、 Measurement and layout

Before construction, it is necessary to conduct measurement and layout work to determine the edge and centerline of the road surface, providing accurate positioning information for the paver. When measuring and laying out, it is necessary to use high-precision measuring instruments to ensure the accuracy of the measurement results.

3、 Concrete mixing and transportation

In the construction of cement concrete slipform paver, the mixing and transportation of concrete are very important links. It is necessary to choose appropriate mixing equipment, control the mix proportion of concrete, and ensure the quality of concrete. At the same time, it is necessary to choose a suitable transportation method to ensure that the concrete does not undergo segregation and collapse during transportation.

4、 Paving operation

The paving operation is the core link of the construction of cement concrete sliding formwork paver. Before paving, it is necessary to debug and inspect the paver to ensure that it is in normal condition. In the paving operation, it is necessary to control the speed and thickness of the paver to ensure the quality of paving. At the same time, it is necessary to pay attention to the operational stability of the paver to avoid problems such as waves and cracks.

5、 Curing and cutting joints

After the construction of the cement concrete slipform paver is completed, maintenance and joint cutting work need to be carried out. Curing is to ensure the quality and strength of concrete pavement, and it is necessary to control the curing time and temperature well. Cutting joints is to prevent cracks and collapse on the road surface, and it is necessary to carry out cutting treatment at the appropriate time. When cutting seams, it is necessary to control the depth and width of the seams to ensure the cutting effect.

6、 Quality inspection and acceptance

After the construction of the cement concrete slipform paver is completed, quality inspection and acceptance work need to be carried out. Quality inspection is to ensure that the construction quality meets the requirements, requiring visual inspection, strength testing, etc. During acceptance, it is necessary to follow relevant standards and specifications to ensure that the project is qualified. At the same time, it is necessary to summarize and evaluate the construction process, summarize experiences and lessons learned, and improve the construction level.
