Automatic paver system with scraper-type drop hopper

Abstract

The invention discloses an automatic paver system with a scraper-type material falling hopper. The automatic paver system with the scraper-type material falling hopper comprises a paving device whichcomprises a supporting structure, a transporting structure and a material distributing structure; the supporting structure is supported on the water bottom surface, the transporting structure is slidably connected to the supporting structure, the material distributing structure is provided with a feeding port and a discharging port for passing of materials, the discharging port extends toward thewater bottom surface, and the transporting structure drives the material distributing structure to move on the supporting structure so as to drive the discharging port to conduct material distributing; and the material distributing structure is connected with scrapers for flat scraping the materials, and the scrapers are arranged on the outer side of the discharging port in a surrounding mode. According to the technical scheme, the material falling position of the scraper-type material falling hopper on the base groove bottom face is accurate, and influence by water flow and wave in the material distributing process is little; and the automatic paver system with the scraper-type material falling hopper is small in overall size and little in working condition limited by a working area and high in cost performance.

Description

technical field [0001] The invention relates to the technical field of underwater paving, in particular to an automatic paver system with a scraper-type hopper. Background technique [0002] In the construction method of the immersed tube tunnel, it is necessary to excavate the foundation groove at the bottom of the water first, and then sink the pipe sections of the tunnel into the pre-excavated underwater foundation groove one by one. After the bottom surface is uneven, it needs to be backfilled with stones for leveling, improving the bearing capacity of the foundation, and controlling its relative settlement, so that each pipe section of the laid-formed 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 work boats in the prior art generally use a floating leveling boat or a platform leveling boat with positioning piles. The floating leveling boat and platform leveling boat...

Problems solved by technology

[0003] In order to improve the flatness of the bottom surface of the foundation groove, 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
