Novel plant cable interlayer structure and implementation method thereof

Abstract

The invention discloses a novel plant cable interlayer structure and an implementation method thereof. The novel plant cable interlayer structure comprises a cable interlayer outer overall stress frame formed by first I-shaped steel and second I-shaped steel, and an inner stress net frame system formed by a first steel channel and a second steel channel is arranged in the outer overall stress frame. An overall space net frame structure is formed by the outer overall stress frame and the inner stress net frame system, and a first cable and a second cable are vertically and horizontally placed in the overall space net frame structure according to the trend of the cables. According to the steel structure interlayer, it is only needed to reserve certain floor height during plant frame structure construction, construction can be carried out after all electrical equipment is purchased in place, the plane view size type and space floor height of the steel structure frame can be adjusted according to the number and trend of actually laid cables, the use efficiency of the reserved space is effectively improved, and the cables are arranged more compactly.

Description

technical field [0001] The invention relates to a novel powerhouse cable interlayer structure, which belongs to the technical field of water conservancy and hydropower engineering monitoring. Background technique [0002] The cable interlayer refers to the structural layer for laying cables entering the control room and (or) electronic equipment room for instruments, control devices, panels, tables, and cabinets. At present, in the design process of power plants of domestic hydropower stations, cable interlayers are often arranged under floors with more electrical secondary equipment in auxiliary power plants. [0003] Such as Figure 4 The implementation process of the conventional cable interlayer of the powerhouse of the hydropower station shown is mainly divided into three steps: (1) In the feasibility study stage of the hydropower station project, the design parameters such as the floor height and design load of the corresponding cable interlayer frame structure are ini...

AI Technical Summary

Problems solved by technology

Because in the design process of hydropower station and industrial control building in the feasibility study stage, it is difficult to finalize the electrical equipment due to factors such as bidding and procurement, and it is difficult to accurately calculate the cable consumption and occupied space in the design accuracy of each specialty. In the actual operation process, it is generally referred to the same type or The design of the cable interlayer for projects of the same scale results in insufficient or wasted space in the implementation stage

[0005] (2) There are many limiting factors for cable placement

When the cable interlayer of reinforced concrete frame structure is traditionally used, due to the overall force of the plant structure, the limitation of floor openings and the influence of space planning, the cable layout space is limited, and the cable routing cannot be optimized, resulting in some cables being wasted

[0006] (3) The cost is high

The construction period of the reinforced concrete frame structure is long, especially when the number of cables is small and the cable interlayer needs to be installed. Under the limitation of the function and cost of each floor of the factory building, the construction of an additional layer of concrete slab beams not only increases the construction time, but also increases the construction cost.

[0007] (4) Difficult to transform

The cable direction of the traditional frame structure is controlled by the opening of the floor during the design stage. If the electrical equipment in the factory needs to be upgraded later, the opening of the floor needs to be adjusted, and the overall force of the floor and part of the structure need to be reinforced. The cost is relatively high High, difficult and difficult to implement

[0008] In addition, the traditional steel-concrete cable sandwich structure still has problems such as complex structure and difficulty in rapid construction, which limits the flexible layout and upgrading of cables inside the plant
