Description

Technical Field

[0001] The present invention relates to the technical field of TRD construction machines, and in particular to a scraper mechanism for a TRD construction machine. Background Art

[0002] The TRD method is a complete set of equipment and construction method that can continuously form walls in various soil layers and gravel layers. Its basic principle is to use a chain saw-type tool box to vertically insert into the stratum and then make horizontal lateral movements. At the same time, the chain drives the tool to make up and down rotational movements, stirring and mixing the original soil and pouring in cement slurry to form a wall of a certain thickness. Its main characteristics are continuous wall formation, smooth surface, uniform thickness, and good wall uniformity. It is mainly used in various construction projects, underground projects, bank protection projects, foundation reinforcement, anti-seepage treatment and other aspects of dams and embankments. The current TRD method machine needs to extend the bottom end of the scraper mechanism into the ground for operation during construction, and only relies on the scraper mechanism set on the outside of the chain for crushing and stirring. The stirring effect and stirring efficiency are poor and need to be improved.

[0003] After searching, the Chinese patent application number CN202210630955.X discloses a cutting box assembly capable of spraying up and down, including a driving wheel assembly, a multi-section unit cutting box, a spraying cutting box, a bottom section cutting box, a driven wheel assembly, and a saw chain. The driving wheel assembly is fixed with a multi-section unit cutting box, a spraying cutting box, a bottom section cutting box, and a driven wheel assembly in sequence, which respectively constitute a set of oil filling pipes, two sets of inclinometer pipes, two sets of air injection pipes, two sets of lower spraying pipes, and two sets of upper spraying pipes. Air is injected through the bottom bevel of the bottom cutting box, and slurry is sprayed through the spray ports on the sides of the bottom cutting box and the spraying cutting box. The cutting box assembly in the above patent has the following shortcomings: it relies solely on cutting components such as saw chains for crushing and stirring, and the stirring effect and stirring efficiency are poor, which needs to be improved.
