Description

Pavement paving device for municipal highway bridge construction Technical Field The invention belongs to the field of road and bridge construction, and particularly relates to a pavement paving device for municipal road and bridge construction. Background The municipal highway bridge construction road mainly uses cement concrete road surface, along with the continuous development of traffic highway level, the requirement of road surface roughness is higher and higher to highway construction's requirement, and road surface roughness is the most important index of highway performance, in concrete road's laying, mostly through road surface paving device to guarantee concrete road's level. The existing pavement paving device is as disclosed in China patent publication No. CN111576145B, cement concrete piled in the middle of a pavement is pushed to two sides of the pavement by arranging guide blocks, the pavement is raked by arranging rotating L-shaped square pipes, and the pavement is trowelled by paving plates, so that the pavement paving effect is good. The following problems still exist in the above technical scheme: 1. the cement concrete can have the situation of position deviation when being piled up in the middle of the pavement, so that the cement concrete is difficult to ensure to be positioned at the middle position of the pavement, the existing paving device can not carry out split-flow adjustment according to the piled up position of the cement concrete, and the heights of two sides of the pavement are different, so that the flatness is influenced; 2.
