How to carry out impact rolling construction of impact roller?Impact roller model selection
Impact roller is an efficient and practical construction machinery and equipment, which is widely used in the construction of highways, railways, water conservancy and other projects. With its unique impact rolling construction method, it can deeply compact the soil, improve the bearing capacity of the foundation, reduce settlement deformation, and ensure the quality and safety of the project. This article will introduce in detail the construction method of impact rollers and how to choose the right impact roller model.
First, the impact rolling construction method of impact roller.
1.How impact rollers work.
The impact roller is pulled by a tractor, driving an impact wheel, and using the weight and travel kinetic energy of the impact wheel itself to impact and roll the soil. In the impact process, the wheel gallery curve of the impact wheel is a cylinder as a whole, and the contact surface between the wheel and the ground is a wave shape. In the process of repeated cycles of each axle of the axle, the horizontal curve is pushed forward along the soil and rock, and each impact completes a cycle and produces subsidence and deformation, so as to obtain the effect of deep compaction.
2.Impact rolling construction steps.
1) Foundation treatment: Before construction, the foundation should be cleaned up, debris, vegetation, etc., and the smoothness and stability of the foundation should be ensured.
2) Measurement lofting: According to the design requirements, the area that needs to be impacted and rolled is measured and lofting, and the construction scope and depth are determined.
3) Impact rolling: select the appropriate impact roller model according to the actual situation, and operate the impact roller according to the requirements to carry out impact rolling construction. In the process of impact rolling, attention should be paid to controlling the driving speed of the impact roller and the overlapping width of the wheel track.
4) Quality inspection: After the impact rolling construction is completed, the quality inspection of the foundation should be carried out, including the detection of compaction and bearing capacity, so as to ensure that the foundation meets the design requirements.
Second, the impact roller model selection.
When choosing an impact roller model, the following factors need to be taken into account:
1.Project type and scale: Different project types and scales require different models of impact rollers. For example, large-scale infrastructure projects such as highways and railways need to choose large-scale impact rollers, while small-scale projects such as urban roads and gardens need to choose small-scale impact rollers.
2.Soil type and properties: The type and nature of the soil is an important factor in the selection of an impact roller model. For example, for loose materials such as sand and gravel, it is necessary to choose a model with a high impact;For tough materials such as clay and silt, it is necessary to choose a model with less impact.
3.Construction requirements and conditions: Different construction requirements and conditions require the selection of different types of impact rollers. For example, for the short construction period, narrow site and other constraints, it is necessary to choose a model with high efficiency;For the construction site is complex, the slope is large and other conditions, it is necessary to choose a model with better adaptability.
4.Equipment performance and technical parameters: Different brands and models of impact rollers have different performance and technical parameters. When selecting a model, it is necessary to understand the performance and technical parameters of each model, and compare and analyze according to the engineering needs.
5.*Maintenance costs: Different brands and models of impact rollers** and maintenance costs vary. When choosing a model, you need to consider the ** and maintenance costs of the equipment, and weigh and choose according to the actual situation.
To sum up, there are a number of factors to consider when choosing the right impact roller model. In the actual selection process, it is necessary to comprehensively consider and analyze various factors to select the most suitable model. At the same time, it is also necessary to pay attention to the requirements of the operation and maintenance of the equipment to ensure the normal operation and service life of the equipment.
