Problems solved by technology

[0003] (1) Affected by seasons and climate, it is difficult to guarantee normal construction progress and construction quality
[0004] (2) In order to speed up the progress of engineering construction, winter construction is often required. Due to the lack of water in concrete maintenance or frost heaving of the foundation, cracks are prone to appear in the cable trench, which affects durability and strength
[0005] (3) During the excavation and filling process of the foundation trench, the environmental impact of flying sand and dust will be cause

Abstract

The invention discloses an assembly-type section steel cable groove box. The groove box comprises a groove box body. The groove box body comprises two groove walls, a base wall and a cover plate. The groove walls are arranged on two sides of groove box body in the width direction. The base wall is arranged at the bottom of the groove box body and is connected between the groove walls. The cover plate is arranged on the top of the groove box body and erected on the two groove walls. The groove walls, the base wall and the cover plate are enclosed to form an accommodation cavity for accommodating cables. The base wall comprises a steel filament net. A concrete pillow is arranged at the bottom of the groove box body. An overhead support used for raising the groove box body above the ground is arranged between the groove box body and the concrete pillow. A wind duct for blowing through of wind is arranged between the groove box body and the concrete pillow. When wind blows through the wind duct, negative pressure is formed under the groove box body, so sand in the accommodation cavity can be blown away. By use of the groove box, sand is effectively prevented from piling up, reduction of working periods is facilitated and the groove box is economical and practical.

Description

technical field [0001] The invention relates to the technical field of cable equipment, and more particularly, to an assembled type steel cable trough box. Background technique [0002] In recent years, with the rapid development of national electric power construction, the power grid planning in various places has been continuously strengthened and improved. As far as eastern Mongolia is concerned, there are abundant coal power, wind power, and photovoltaic resources. The power of major power plants needs to be sent out in a centralized manner. Therefore, the number of substations and converter stations in this region will gradually increase. At the same time, due to climatic reasons, it is drought and water shortage all the year round, the temperature difference between seasons and day and night is large, the winter is long, the freezing depth is large, and the sandstorm is more serious in spring and autumn. In this case, if the traditional concrete brick cable trench (in...
