Abstract

The invention discloses a fiber concrete duct piece with good corrosion resistance, and relates to the technical field of concrete duct pieces, the fiber concrete duct piece comprises a fiber concrete duct piece main body, a connecting locking piece and a connecting locking groove, the connecting locking piece is fixedly mounted at one end of the fiber concrete duct piece main body, and the connecting locking groove is fixedly mounted at the other end of the fiber concrete duct piece main body; the connecting locking groove is formed in the other end of the fiber concrete pipe piece body. Through mutual cooperation of the connecting locking pieces, the connecting locking grooves, the positioning lock holes, the outer rigid sleeve shell and the inner soft sleeve shell, and through matching of the connecting locking pieces and the connecting locking grooves, when the fiber concrete pipe piece main body is used in a matched mode, the positioning lock holes and the positioning rods can complete rapid installation of the fiber concrete pipe piece main body, and the installation efficiency of the fiber concrete pipe piece main body is improved. And meanwhile, in cooperation with rebounding of the inner soft sleeve shell, the sealing fit effect at the joint is more perfect when the fiber concrete duct piece body is positioned and installed, and the use efficiency of the fiber concrete duct piece is further improved.

Description

technical field [0001] The invention relates to the technical field of concrete segments, in particular to a fiber concrete segment with good corrosion resistance. Background technique [0002] The fiber concrete segment is the main assembly component of the engineering construction, and is the innermost barrier during the engineering construction. It bears the role of resisting soil pressure, groundwater pressure and some special loads. The quality of the fiber concrete segment is directly related to the quality of the engineering construction. The overall quality and safety affect the waterproof performance and durability of engineering construction. The production of fiber concrete segments usually uses high-strength impermeable concrete to ensure reliable load-bearing and waterproof performance. The production mainly uses the finished segment mold after sealing and pouring concrete. Ready to shape. [0003] There are following problems at prior art: [0004] When the f...
