Structure reinforced cable duct module

Abstract

The invention discloses a structure reinforced cable duct module. The front end and the rear end of the structure reinforced cable duct module in the longitudinal direction are respectively provided with a socket and a bell mouth for longitudinal butt joint positioning; the upper surface and the lower surface of the structure reinforced cable duct module are respectively provided with matched concave-convex groove structures for vertical butt joint positioning; the profile steel is arranged on the two longitudinal sides of the structure reinforced cable duct module respectively, matched tenonsor grooves are formed at the upper portion and the lower portion of the profile steel, matched tenons or grooves are also formed at the left portion and the right portion of the profile steel, and corresponding bolt holes are formed in the tenons and the grooves. The structure reinforced cable duct module can achieve modular production and modular assembly, thereby greatly simplifying the designprocess; in addition, the modularized cable duct can be constructed mechanically, is convenient to transport and stack, has a fast engineering progress, does not need to support a formwork and cast concrete, does not need to maintain the concrete, and greatly saves the construction time; and moreover, the profile steel framework spliced together on two sides of the cable duct structure ensures therigidity of the joint and greatly improves the bearing capacity performance and the overall rigidity of the cable duct structure.

Description

technical field [0001] The invention relates to the field of electric power construction, in particular to a structurally reinforced cable pipe arrangement module. Background technique [0002] With the development needs of urbanization construction, power cables have gradually changed from aerial erection to underground laying. Traditional cable laying generally adopts the form of cable pipe laying, that is, excavating foundation trenches on site, laying cable pipes, and then pouring concrete for curing. This traditional method has disadvantages such as large construction area, long construction period, and serious site pollution. Especially in the process of laying municipal cable pipes, it will cause urban roads to be blocked, and concrete pouring on site will pollute the environment and seriously affect people's daily life. , does not meet the needs of modern urban development. [0003] In addition, with the increase of the mileage of cable pipes in operation, an impor...

Problems solved by technology

This traditional method has disadvantages such as large construction area, long construction period, and serious site pollution. Especially in the process of laying municipal cable pipes, it will cause urban roads to be blocked, and concrete pouring on site will pollute the environment and seriously affect people's daily life. , does not meet the needs of modern urban development

[0003] In addition, with the increase in the mileage of cable pipes in operation, an important problem has been found in the practice of operation and maintenance, that is, the structure of cable pipes in operation has been damaged and destroyed

This is because the rigidity of the pipe arrangement itself is small and the resistance is insufficient, coupled with the influence of external operations on the cable pipe arrangement, it is easy to cause uneven settlement and structural damage to the cable pipe arrangement

[0004] Application No. 201810959567.X "A Cable Conduit and Its Construction Method" and 201811001829.8 "A Prefabricated Cable Conduit and Its Construction Method" respectively disclose two prefabricated cable conduits. Various problems of traditional cast-in-place pipes have been solved, and its connection methods have also been introduced, but the connection methods are generally too complicated, and a matching interface splicing structure is required to complete the splicing, and there are problems such as insufficient rigidity at the joints; The advantages of unified modularization of the interface cannot simplify the design process of the cable duct; it cannot solve the problem that the cable duct structure is prone to damage and destruction encountered in the current operation and maintenance
