Description

Technical Field

[0001] This utility model relates to the field of water-stabilized layer texturing technology, and in particular to an automatic texturing and combing device for water-stabilized layers. Background Technology

[0002] In the construction of infrastructure such as roads and squares, cement-stabilized crushed stone layer (referred to as water-stabilized layer) is a key base structure. Its construction quality plays a decisive role in the performance and service life of the entire project. Roughening treatment is an important process in the construction of water-stabilized layer. After paving and compaction, the surface of water-stabilized layer is usually relatively smooth and flat. However, this smooth surface will reduce the bonding force between it and the upper asphalt concrete surface layer, affecting the integrity and durability of the road structure. Through roughening treatment, textures of a certain depth and spacing can be formed on the surface of water-stabilized layer, increasing the surface roughness, thereby improving the bonding performance with the upper structure, effectively preventing the occurrence of defects such as interlayer slippage and peeling, and ensuring the safe use of the road.

[0003] The types and proportions of raw materials for existing water-stabilized layers vary depending on project requirements and material supply. Water-stabilized layers with different material properties also have different requirements for surface hardness and texture after compaction. Water-stabilized layers with higher cement dosage and more fine aggregate content have relatively hard surfaces, requiring a roughening rake at a larger angle and with stronger force to roughen them and form a suitable texture. On the other hand, water-stabilized layers with lower cement dosage and more coarse aggregate content have relatively lower surface hardness. If the same fixed angle is used for roughening, it may lead to excessive roughening, which may damage the structure of the water-stabilized layer and affect its strength and stability. Traditional fixed-angle roughening rake combing devices cannot adjust the angle of the roughening rake in time according to the changes in the material properties of the water-stabilized layer, making it difficult to ensure the consistency and stability of roughening quality. Therefore, we propose an automatic roughening rake combing device for water-stabilized layers. Utility Model Content
