Embodiment Construction

[0023] The present invention will be further described below in conjunction with the examples, but not as a basis for limiting the present invention.

[0024] Embodiments of the invention

[0025] A double-wall corrugated pipe socket reinforcement method is to sequentially cover a flexible inner layer and a reinforced shell outside the socket of a solid-walled double-wall corrugated pipe, and provide a deformation space during socketing through the flexible function of the flexible inner layer. The shell increases structural strength.

[0026] A double-wall corrugated pipe socket profiling cladding structure for realizing the above method, as attached Figure 1-6 As shown, it includes a contoured flexible inner layer 7 coated on the outer wall of the double-wall bellows socket 5 , and the contoured flexible inner layer 7 is covered with a contoured reinforced shell 3 .

[0027] The profiling flexible inner layer 7 and the profiling reinforced shell 3 are independently proces...

Abstract

The invention discloses a double-wall corrugated pipeline bell and spigot strengthening method and a profiling wrapping structure. The exterior of a double-wall corrugated pipe bell and spigot of a solid wall is sequentially wrapped by a flexible inner layer and a strengthening outer shell, deformation space during bearing and inserting is provided due to the flexible function of the flexible inner layer, and the structure strength is improved through the strengthening outer shell. The profiling wrapping structure comprises a profiling flexible inner layer wrapping the outer wall of the double-wall corrugated pipe bell and spigot, and the outer wall of the profiling flexible inner layer is wrapped by a profiling strengthening outer shell. According to the method and the structure, the problem about strength of a bearing inserting head can be solved, the problem about the deformation space can be solved as well, and in addition, the characteristics that preparing and installing are simple, and the structure is firm are achieved.

Description

technical field [0001] The invention relates to a method and a structure for strengthening a socket of a double-wall corrugated pipe, in particular to a method for strengthening a socket of a double-wall corrugated pipe and a profiling covering structure. Background technique [0002] Since its appearance, plastic double-wall corrugated pipes have been widely used in various drainage and irrigation pipe network systems due to their excellent performance. Existing plastic double-wall corrugated pipes are continuously produced through extrusion molding, and socket connections are mainly used for the connection between pipes; Realize quick connection between pipes. [0003] The socket and the socket are extruded together with the main body of the pipe. However, due to the limitation of the molding process, the socket is generally a solid wall structure with a thin wall thickness. Compared with the double-wall corrugated main body of the pipe, the strength of the socket is the ...
