Embodiment 1

[0025] The invention discloses a cable trench cover plate, the specific results are as follows Figure 1-2 As shown, frame 1 is included, wherein frame 1 is a square frame welded by four L-shaped steel plates, the L-shaped steel plate in the present invention is a galvanized angle iron, and the inner wall of frame 1 short side is symmetrically welded steel pipe 2, and steel pipe 2 is Hollow structure, with a through hole 3 inside, and a round hole 4 connected to the steel pipe 2 on the short side of the frame 1, and a steel bar 5 at the bottom of the frame 1, where the steel bar 5 is arranged at the bottom of the frame 1, and the long side of the frame 1 is uniform Four steel bars 2 are welded. The front end of the steel pipe 2 is provided with a slot 6. The steel bars 5 welded on both sides of the long side of the frame 1 pass through the slot 6. The top of the steel tube 2 corresponds to the welded steel bar 5. The distribution of the steel bars is as follows: figure 1 shown...

Embodiment 2

[0029] In order to reduce the weight of the cable trench cover plate of the present invention and ensure the strength simultaneously, the present invention improves the formula of the concrete filled in the cover plate, specifically:

[0030] The concrete is lightweight concrete, which is mixed with the following raw materials in parts by weight: 10 parts of Portland cement, 3 parts of silica fume, 8 parts of fly ash, 4 parts of acrylic fiber, 3 parts of calcium sulfate whiskers, styrene-butadiene rubber 2 parts of powder, 2 parts of styrene-acrylic emulsion, 9 parts of water, 0.1 part of foaming agent, 2 parts of sodium silicate, and 0.5 part of thickener.

[0031] Wherein the acrylic fiber has a diameter of 15-20 μm and a length of 1-3 mm, and a calcium sulfate whisker has a diameter of 1-8 μm and a length of 100-200 μm.

[0032] The thickener is a mixture of hydroxypropyl methylcellulose and polyethylene glycol in a weight ratio of 1:1.

[0033] The foaming agent is formed...

Embodiment 3

[0036] The difference between this embodiment and embodiment 2 is:

[0037] The concrete is lightweight concrete, which is mixed with the following raw materials in parts by weight: Portland cement 10.5 parts, silicon fume 3.5 parts, fly ash 7 parts, acrylic fiber 4 parts, calcium sulfate whiskers 2.5 parts, styrene-butadiene rubber 2.5 parts of powder, 2 parts of styrene-acrylic emulsion, 9 parts of water, 0.15 parts of foaming agent, 2.2 parts of sodium silicate, and 0.4 parts of thickener.

[0038] Wherein the acrylic fiber has a diameter of 15-20 μm and a length of 1-3 mm, and a calcium sulfate whisker has a diameter of 1-8 μm and a length of 100-200 μm.

[0039] The thickener is a mixture of hydroxypropyl methylcellulose and polyethylene glycol in a weight ratio of 1:1.

[0040] The foaming agent is formed by mixing animal protein foaming agent and sodium dodecylsulfonate in a weight ratio of 1:1.

Abstract

The invention discloses a cable trench cover plate, comprising a frame. The frame is a square frame fixed by four L-shaped steel plates. Steep pipes are symmetrically arranged on the inner walls of the short sides of the frame. Through holes are arranged in the steel pipes, and round holes communicated with the steel pipes are arranged in the short sides of the frame. Steel bars are arranged at the bottom of the frame. The frame is filled with concrete. The cable trench cover plate is convenient to handle, labor-saving and practical.

Description

technical field [0001] The invention relates to the technical field of substation maintenance, in particular to a cable trench cover plate. Background technique [0002] Affected by factors such as the design capacity of the substation, the number of installed equipment, and the installation method, different cable trenches have different depths and widths, so the materials, sizes, and dimensions of the cable trench covers used are also different. The cables in the prior art Most of the trench cover slabs are reinforced concrete slabs, which can be ordered from manufacturers or designed, constructed and installed by ourselves. The installation of the cable trench cover is generally manual hoisting, handling and loading and unloading, but because most of the cable trench covers do not have a suitable stress point, it is extremely inconvenient to manually lift, transport, and install, and the excessive force on the fingers may easily cause bruises and crush injuries. And in ...
