Description

A kind of construction equipment used for planting interlayer treatment process

technical field

The invention belongs to the field of road construction equipment, and in particular relates to a construction equipment used for a stone-planting interlayer treatment process.

Background technique

At present, composite pavement has been widely used in highway construction in my country. Compared with flexible pavement, asphalt concrete-cement concrete composite pavement structure can reduce the amount of asphalt, and can make up for the poor driving comfort and difficult maintenance of rigid pavement. shortcoming. However, due to the large modulus gap between the asphalt pavement and the cement concrete base, as well as insufficient interlayer cohesion, slip damage often occurs.

At present, there are no clear regulations in the relevant specifications of asphalt and cement pavement regarding the treatment methods of the intermediate interface layer of composite pavements. The treatment methods for the interface layer of flexible composite pavement include: sandblasting, milling, roughening, and notching.

However, under the influence of heavy traffic and other factors, the traditional interlayer treatment methods are still difficult to provide sufficient interlayer shear resistance. The patent "A Stone-planting Interlayer Treatment Method and Composite Pavement Paved by It" discloses a stone-plant interlayer treatment method of embedding aggregates on the cement concrete layer, and there are currently research and application results in physical engineering It shows that the use of stone-planting interlayer treatment method can form a rough surface on the cement concrete layer. Compared with the traditional treatment methods such as engraving grooves, the shear strength of the interface layer has been significantly improved; the cement board surface treatment method When planting stones is used, the composite pavement has good resistance to the repeated action of water and vehicle loads. This is because the effect of the surface structure of the cement board formed by planting stones is similar to that after paving the synchronous crushed stone seal layer. Moreover, the crushed stone is integrated with the cement board and is more firm. Therefore, the residual shear strength ratio of the cement board for stone planting treatment is relatively large, the effect is remarkable, and it has good promotion value.

The stone planting method is that when the cement concrete pavement reaches the initial setting after the paving is completed, the stones with a particle size of 9.5-19mm are evenly spread on the concrete, and the stones are evenly pressed until their particle size sinks into about 2/3 of the concrete. Since the stone spreading is carried out when the cement concrete is initially set, the road surface cannot bear the load, so any kind of crushed stone spreader currently in use cannot be applied to the spreading work of this method, and the pressing work after the stone spreading is also ineffective. The construction of the supporting equipment can only be carried out manually, the work is cumbersome, and the construction quality is difficult to guarantee; in order to solve this problem and improve the construction efficiency and quality, there is an urgent need for a new design at this stage. Stone-planting, construction equipment that can be integrated and automatically operated.
