Abstract
The utility model relates to an arc support of a tunnel large-section cable. The arc support of the tunnel large-section cable comprises an angle iron connecting block, an arc stand column and a cross arm, a pre-buried steel belt is arranged in the inner side walls of the tunnel, the arc stand column is fixed on the pre-buried steel belt through the angle iron connecting block, the cross arm is horizontally arranged, and one end of the cross arm is connected with the arc stand column. Compared with the prior art, the arc support of the tunnel large-section cable has the advantages of being firm in structure, space-saving and the like.
Description
Technical field
The utility model relates to a kind of cable bearer, especially relates to the curved support of a kind of tunnel electric cable with large cross-section.
Background technique
Because the requirement of high voltage, heavy in section cable transmission capacity, heat radiation around the cable is had relatively high expectations, system of layings such as original Shanghai comb commonly used, direct-burried, cable channel have been not suitable for the needs of this type of cable, and therefore building the electric power dedicated tunnel becomes the main mode that high voltage, electric cable with large cross-section are laid.The design of tunnel support and application facet in the past, structural type and selection are all more single, can not adapt to different cables lays form in different environment needs; In with the circular electric power tunnel of living, great majority still adopt is that the form (as shown in Figure 1) of lineal shape support has been wasted certain tunnel space.
The model utility content
The purpose of this utility model is exactly the curved support that provides a kind of sound construction for the defective that overcomes above-mentioned prior art existence, saves the tunnel electric cable with large cross-section in space.
The purpose of this utility model can be achieved through the following technical solutions:
The curved support of a kind of tunnel electric cable with large cross-section, comprise angle steel contiguous block, arc column and cross-arm, the madial wall in described tunnel is provided with pre-buried steel band, described arc column is fixed on the pre-buried steel band by the angle steel contiguous block, described cross-arm is horizontally disposed with, and the one end is connected in the arc column.
The radian of described arc column is less than pi/2 rad.
Described arc column is fixed on the pre-buried steel band by at least 4 angle steel contiguous blocks.
Described cross-arm is provided with at least two, vertically arranges, an end of cross-arm connects the arc column, and the other end flushes.
Compared with prior art, arc column of the present utility model is fixed on the pre-buried steel band of tunnel madial wall, is close to the tunnel madial wall, fixes by at least 4 angle steel contiguous blocks, not only can improve structural strength, and can save the space.
Description of drawings
Fig. 1 is the structural representation of traditional line shape support;
Fig. 2 is structural representation of the present utility model;
Among the figure, 1a is the arc column, and 1b is the lineal shape column, and 2 is the angle steel contiguous block, and 3 is cross-arm, and 4 is the madial wall in tunnel.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 2, the curved support of a kind of tunnel electric cable with large cross-section comprises angle steel contiguous block 2, arc column 1a and cross-arm 3.In order to fix this curved support, the pre-buried steel band of one circle need be set at the madial wall 4 in tunnel, arc column 1a is fixed on the pre-buried steel band by angle steel contiguous block 2, column structure by arc, can utilize in the traditional line shape support some unserviceable spaces between support and the tunnel madial wall.
In order to guarantee its join strength, at least 4 angle steel contiguous blocks 2 generally are set at certain intervals connect.Cross-arm 3 is horizontally disposed with, and the one end is connected on the arc column 1a, and the other end keeps flushing.For can the better utilization space, the engine request setting that quantity that can cross-arm 3 can be concrete under the premise that security is guaranteed, vertically arranges many rows.
Claims (4)
1. the curved support of a tunnel electric cable with large cross-section, it is characterized in that, comprise angle steel contiguous block, arc column and cross-arm, the madial wall in described tunnel is provided with pre-buried steel band, described arc column is fixed on the pre-buried steel band by the angle steel contiguous block, described cross-arm is horizontally disposed with, and the one end is connected in the arc column.
2. the curved support of a kind of tunnel according to claim 1 electric cable with large cross-section is characterized in that the radian of described arc column is less than pi/2 rad.
