Automatic paving machine system with movable material falling structure and working method thereof

Abstract

The invention discloses an automatic paving machine system with a movable material falling structure and a working method thereof. The system comprises a paving device, at least one material falling structure and a conveying structure; the paving device comprises a supporting structure which is supported on the water bottom surface; the material falling structure is provided with a material feeding port and a material discharging port, wherein the material discharging port extends towards the water bottom surface; and the conveying structure comprises a first sliding rail structure and a second sliding rail structure, wherein the first sliding rail structure extends in the longitudinal direction, the second sliding rail structure extends in the transverse direction, the material falling structure is connected to the first sliding rail structure and longitudinally moves along the first sliding rail structure, the second sliding rail structure is arranged on the supporting structure, thetwo ends of the first sliding rail structure are connected to the second sliding rail structure and transversely moves along the second sliding rail structure to drive the material falling structureto move in the transverse direction. According to the technical scheme, when the automatic paving system is used for performing underwater gravel bedding, the laying precision can be improved, the influence of the water flow and waves can be reduced, and the system can be applied to requirements of different water depths.

Description

technical field [0001] The invention relates to the technical field of underwater paving technology, in particular to an automatic paver system with a movable blanking structure 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. In order to improve the flatness of the bottom surface of the foundation trench, the workboats in the prior art generally adopt floating screeds with spuds or platform screeds, and the floating screeds with sp...

AI Technical Summary

Problems solved by technology

In order to improve the flatness of the bottom surface of the foundation trench, the workboats in the prior art generally adopt floating screeds with spuds or platform screeds, and the floating screeds with spuds and platform screeds generally It includes a distribution pipe, which goes deep into the bottom of the water directly, and the overall length of the distribution pipe is long, and its underwater part is easily affected by water flow and waves, which reduces the leveling accuracy
