In the existing concrete pavement paving process in the tunnel, the traditional concrete pavement paving consumes a lot of manpower for manual paving, invests a lot of energy, takes too long, and is inefficient. The concrete is spread and leveled manually, scraped manually by a scraper, and the pavement is compacted and formed by manually controlled vibration equipment. The construction progress is slow. Once a step or depression appears in the middle of the pavement, bubbles and cold seams are prone to occur after the manually spread concrete solidifies. Due to the large span of the concrete pavement, the scraper cannot reach it for repair, and the construction quality of the concrete pavement is difficult to guarantee, resulting in uneven concrete pavement after construction. Generally, after construction, the repair method is used to complete the construction after waiting for the concrete to solidify. The phenomenon of errors in the overall horizontal surface of the construction is relatively common, which affects the later construction. In view of the above reasons, a combined trolley of a paver and a tunnel invert trestle is proposed. Utility Model Content
