Description

A kind of anti-wind and sand cable ditch

Technical field:

The utility model belongs to the technical field of electric power protection, in particular to a wind and sand prevention cable ditch.

Background technique:

Our country has a vast territory, and many areas in the northwest are connected with deserts. The annual climate is cold in winter and hot in summer, with a large difference in daily temperature between day and night, and dusty weather is common. When designing substations, it is necessary to optimize the wind and sand protection of buildings and structures. At present, most power transmission and transformation projects implement unattended substations. Cable trenches are one of the important infrastructures in substations. It is particularly important to optimize their design schemes to meet their sand prevention requirements in the windy and sandy areas of Northwest China. The cable trench is a kind of underground channel that can be opened for laying cables. It includes a bottom plate with a side wall on the bottom plate and a cover plate on the side wall; ditch. For this reason, aiming at the area with strong wind and sand in the northwest, it can effectively prevent wind and sand from entering the cable trench, and a special cable trench for wind and sand prevention has been developed.

Invention content:

The purpose of the utility model is to provide a cable trench for wind and sand, which can effectively prevent wind and sand from entering the cable trench, and adopts a prefabricated cable trench cover, which can speed up construction, reduce on-site wet work, save equipment investment, and has a large economic benefits.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

A wind and sand-proof cable trench, which includes a bottom plate and a side wall made of concrete, is characterized in that: an outward groove is provided on the outer side of the upper end of the side wall, and an upper cover type cable trench cover plate is installed on the groove.

The upper cover type cable trench cover plate is composed of a tongue-and-groove cover plate group and a flat-mouth type cover plate. The tongue-and-groove cover plate It is connected with the tongue-and-groove cover group by a flat cover, which can be disassembled directly for easy maintenance.

The tongue-and-groove cover is a modular cover with a groove on one side and a tenon on the other side, and the tongue-and-groove cover is connected with the tongue-and-groove cover.

The beneficial effects of the utility model:

(1) The utility model adopts the upper cover type cable trench cover plate, and the connection between the cover plate and the cover plate is inserted by a tongue and groove, which greatly improves the sand prevention ability of the cable trench;

(2) The wind and sand-proof cable trench adopts prefabricated cable trench cover plate, which can be disassembled quickly, can speed up the construction speed, reduce on-site wet work, save equipment investment, and have great economic benefits.

Detailed ways:

The technical solution of the utility model will be described in detail below in conjunction with the accompanying drawings.

As shown in Figures 1 to 3, a wind and sand-proof cable trench includes a bottom plate 1 and a side wall 2 made of concrete. The slot 3 is equipped with an upper cover type cable trench cover plate 4; the upper cover type cable trench cover plate 4 is formed by combining and plugging the tongue and groove cover plate group and the flat mouth type cover plate 5, and the tongue and groove type cover plate group consists of several The tongue-and-groove cover plates 6 are plugged together, and the tongue-and-groove cover plate group and the tongue-and-groove cover plate group are connected by a flat-mouth cover plate 5; wherein, the tongue-and-groove cover plate 6 is provided with a groove on one side 7. The other side is provided with a modular cover plate with a tenon 8, and the tongue-and-groove cover plate 6 is connected with the tongue-and-groove cover plate 6 in a tongue-and-groove insertion mode.

At the construction site, the use method of the wind and sand protection cable trench is as follows:

(1) Design the size of the wind and sand cable trench according to the actual project, the length of the wind and sand cable trench is 1m as the modulus, and the bottom plate and side wall of the concrete cast-in-place cable trench are used;

(2) Prepare the prefabricated cover-type cable trench cover, which is a modular cover with a groove and a unified plate length of 1m;

(3) After the cast-in-place cable trench is finally set, configure and install the upper-cover cable trench cover.
