Pavement paver capable of spanning central median for construction and construction method thereof

Abstract

The invention relates to a pavement paver capable of spanning a central median for construction and a construction method thereof. The pavement paver comprises a stander, a crawler wheel and a paving device, wherein the stander comprises two main beam frames and two side beams which are connected at the left and the right ends of the main beam frames; two strips of lifting side moulds are symmetrically distributed at the left and the right sides of the main beam frames; a first lengthening arm and a second lengthening arm are fixedly connected between the side beam and the outer side of the lifting side mould as well as the two main beam frames; a third lengthening arm is also fixedly connected between the rear of the second lengthening arm as well as the side beams and the lifting side moulds; a reinforcing connecting rod is respectively connected between the first lengthening arm and the second lengthening arm as well as between the second lengthening arm and the third lengthening arm; and triangular brackets are fixedly connected among the first lengthening arm, the second lengthening arm and the third lengthening arm upwards. The invention realizes continuous paving of a bridge surface, ensures the uniformity of a pavement, a lap joint board and the bridge surface, guarantees the continuity of construction, and improves the evenness of the pavement.

Description

technical field The invention relates to a large sliding form paver and a construction method thereof, in particular to a concrete pavement paver and a construction method thereof. Background technique With the continuous development of expressways in our country, cement concrete pavement has been widely used in Tongshan Expressway. At the same time, the requirements for slipform paving cement concrete pavement construction technology and road construction machinery are getting higher and higher. Referring to Fig. 1, in the existing expressway construction, the maximum paving width of the traditional concrete pavement paver is 12m, and it faces two problems in actual construction: 1. When the paver is paving the bridge deck, its The left or right track walking position is just at the central anti-collision barrier of the bridge. To realize continuous mechanical paving, the construction of the central anti-collision barrier needs to be delayed. However, in order to ensure the...

AI Technical Summary

Problems solved by technology

The purpose of the present invention is to provide a pavement paver and its construction method that can be constructed across the central divider, to solve the technical problem that the traditional concrete pavement paver cannot continuously pave the bridge deck; When the paver is paving the road, it is prone to slipping and cannot maintain normal synchronous walking.
