Description
Technical Field
The invention relates to a road paving vibration rolling device, in particular to a vibration rolling device of a bedding material spreading machine.
Background
The underlayer (bed) refers to a structural layer provided below the base layer. The water-proof and anti-freezing soil foundation mainly has the functions of water isolation, water drainage and freezing prevention so as to improve the working conditions of the foundation layer and the soil foundation, and has better water stability requirement. The cushion layer is a structural layer between the base layer and the soil foundation, and is used for improving the water stability of the soil foundation and improving the water stability and frost heaving resistance of the pavement structure when the water stability of the soil foundation is poor, and can diffuse load so as to reduce the deformation of the soil foundation. Therefore, the method is usually installed when the soil base is in a poor wet or warm condition. The strength requirements of the bedding material are not necessarily high, but its water stability must be good. The underlayer application conditions and general specifications are as follows: 1. road sections where the foundations are often wet and over-wet, and where freezing hazards occur in seasonally frozen areas, should be cushioned. 2. The cushion material includes two types of granular material and inorganic binder stabilized soil. The aggregate includes natural gravel, coarse sand, slag, etc. When coarse sand and natural gravel are adopted, the content of particles smaller than 0.074mm is less than 5 percent; when slag is used, the content of particles smaller than 2mm is preferably smaller than 20%. The cushion layer is divided into two types of rigidity and flexibility (also called boiling rigidity). The rigid underlayment is typically a C7.5-C10 concrete ramming which is suitable for thin large integral and block facings; the flexible cushion is generally formed by compacting various bulk materials, such as sand, slag, crushed stone, lime soil, etc., and is suitable for thick block-shaped surface layers. 3. The thickness of the cushion layer is determined according to local experience, and when the total thickness of the pavement in the seasonal freezing area is less than the minimum thickness for freezing prevention, the cushion layer material is used for supplementing. The shim is to be noted to distinguish from the base. It is easy to confuse these two engineering concepts. The cushion layer and the base material are not divided by materials at the same time, and the design will be elucidated. When the materials are the same concrete, the calculation is larger than 20CM to calculate the foundation, and is smaller than or equal to 20CM to calculate the cushion layer. The design of the cushion layer needs to consider the bearing of the foundation and the foundation. The cushion layer is a middle layer of a reinforced concrete foundation and foundation soil, has the functions of leveling the surface of the cushion layer, facilitating the binding of reinforcing steel bars on the cushion layer, also has the function of protecting the foundation, is all plain concrete, and does not need to add reinforcing steel bars. If the reinforcing steel bars exist, the reinforcing steel bars cannot be called a cushion layer and are regarded as a foundation slab.
The bedding material is a bottom material in a structural level, and in some civil construction requiring multilayer laying, the bedding material is required to be used for supporting or isolating a bottom layer, and particularly, in the process of filling and laying a dam, the laid main material can be isolated from the soil ground through the bedding material, so that the influence of soil on the main material is effectively avoided.
