Automatic paver system with adjustable feet and method of operation

Abstract

The invention discloses an automatic paver system with adjustable supporting legs and a working method of the automatic paver system. The automatic paver system with the adjustable supporting legs includes a paving device. The paving device includes a supporting frame, the adjustable supporting legs, a conveying structure and a distributing structure, wherein the adjustable supporting legs includea driving part, a connecting part and supporting leg bodies, the connecting part and the supporting leg bodies are connected with the driving part, the connecting part is connected with the supporting frame, and the supporting leg bodies are supported on a water bottom surface, and driven by the driving part, the connecting part moves up and down relative to the supporting leg bodies to adjust the height of the supporting frame to the water bottom surface; the conveying structure is connected with the supporting frame in a sliding mode; amd the distributing structure is connected with the conveying structure and is provided with a feeding hole and a discharging hole which are used for allowing materials to pass through, the discharging hole extends to the water bottom surface, and the conveying structure drives the distributing structure and the supporting frame to move and drives the discharging hole to conduct material falling. According to the technical scheme of the automatic paver system, the position of material falling is precise; and in the distributing process, the influence of water current and wave is small; working conditions are less limited by a working area; and thecost performance is high.

Description

technical field [0001] The invention relates to the technical field of underwater paving, in particular to an automatic paver system with adjustable feet and a working method thereof. Background technique [0002] In the construction method of the immersed tube tunnel, it is necessary to excavate the foundation trench at the bottom of the water first, and then submerge the pipe sections of the tunnel into the pre-dug underwater foundation trench one by one. Afterwards, its bottom surface is uneven, and it needs to be backfilled with stones for leveling, so as to improve the bearing capacity of the foundation and control its related settlement, so that the force of each section of the laid tunnel can be evenly stressed and the use effect is good. [0003] In order to improve the flatness of the bottom surface of the foundation trench, the workboats in the prior art generally adopt floating screeds or platform screeds with positioning piles. The leveling accuracy is directly ...

Problems solved by technology

[0003] In order to improve the flatness of the bottom surface of the foundation trench, the workboats in the prior art generally adopt floating screeds or platform screeds with positioning piles. The leveling accuracy is directly affected by the water flow and waves, and the working conditions are limited; the platform type leveling ship uses pile legs to support the platform above the water surface, and the paving accuracy under this structure is less affected by the water flow, but its work conditions are still restricted
