Concrete spreading and paving device for road building

Abstract

The invention discloses a concrete spreading and paving device for road building. The concrete spreading and paving device for road building comprises a spreading and paving trolley body, a concrete storing tank, a spreading and paving mechanism and a spreading and paving evening mechanism; a bearing bottom plate is arranged at one end of the spreading and paving trolley body, and the bearing bottom plate and the spreading and paving trolley body are each provided with moving wheels; the concrete storing tank is installed on the top of the bearing bottom plate; the end, away from the spreadingand paving trolley body, of the bearing bottom plate is provided with the spreading and paving mechanism; the top of the concrete storing tank is provided with a feeding hopper which communicates with the concrete storing tank; and a mixing rotating shaft is rotationally installed in the concrete storing tank through a bearing pedestal. The concrete spreading and paving device for road building is reasonable and simple in structure, and convenient to use, effectively improves the road building construction efficiency, and lowers the labor intensity of personnel for road building; due to double-layer paving, air in concrete is discharged through a concrete vibrating rod, the structural strength of road concrete spreading and paving is effectively improved, the road building quality is guaranteed, road concrete paving is smoother due to balance of spreading and paving feeding, and practicability is higher.

Description

Technical field: [0001] The invention relates to the technical field of road construction, in particular to a concrete paving device for road construction. Background technique: [0002] Cement concrete pavement refers to the pavement with cement concrete as the main material, referred to as concrete pavement, also known as rigid pavement, commonly known as white pavement, it is a high-grade pavement, cement concrete pavement has plain concrete, reinforced concrete, continuous reinforcement Concrete, prestressed concrete and other road surfaces, but the efficiency of the existing concrete paving equipment for road construction is low. After one feeding, there are air bubbles in the concrete at the bottom, which affects the structural strength of the concrete road and requires manual post-repair. , increase the labor intensity of personnel, and the uniformity of paving is poor, and the practicability is not strong. Invention content: [0003] The purpose of the present inv...
