Abstract
The utility model provides a cast-in-situ power tunnel. The cast-in-situ power tunnel comprises a tunnel body; a rectangular tunnel hole is formed in the tunnel body; and a convex pavement is arranged on the bottom surface of the tunnel hole. According to the cast-in-situ power tunnel provided by the utility model, as the tunnel hole is of a rectangular shape, the arrangement, inspection and maintenance of cables are convenient; and moreover, as the convex pavement is arranged on the bottom surface of the tunnel hole, the maintenance personnel can conveniently walk in the tunnel.
Description
Technical field
The utility model relates to the field, tunnel, in particular to a kind of cast-in-place electric power tunnel.
Background technology
Common cast-in-place electric power tunnel forms the tunnel for circular pipe is set in the raceway groove that excavates, this tunnel is in practice of construction and use procedure, be unfavorable for the cable of arranging, and the space availability ratio of the cast-in-place electric power tunnel of this circle is not high, is unfavorable for that personnel patrol in the tunnel and overhaul power cable.
The utility model content
The utility model aims to provide a kind of cast-in-place electric power tunnel of the cable of conveniently arranging.
The utility model provides a kind of cast-in-place electric power tunnel, comprises the tunnel main body, and the tunnel main body has the Tunnel-hole of rectangle, is provided with the pavement of protrusion on the bottom surface of Tunnel-hole.
Further, be provided with the cable support of laying cable in the Tunnel-hole.
Further, be embedded with hold-down screw on the sidewall of Tunnel-hole, cable support is fixedly installed on the pre-buried hold-down screw.
Further, cable support is arranged on the two side of Tunnel-hole symmetrically.
Further, the corner of the end face of Tunnel-hole and sidewall has chamfering.
Further, the tunnel main body adopts reinforced concrete structure.
Further, also comprise the concrete cushion that is arranged on the tunnel lower body part.
According to cast-in-place electric power tunnel of the present utility model, be set to rectangle by Tunnel-hole, conveniently arrange cable and inspection and maintenance cable, and be provided with the pavement of protrusion in the bottom surface of Tunnel-hole, make things convenient for the maintainer to walk at tunnel internal.
Description of drawings
The accompanying drawing that consists of the application's a part is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the cross-sectional configuration schematic diagram according to cast-in-place electric power tunnel of the present utility model.
The specific embodiment
Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As shown in Figure 1, according to cast-in-place electric power tunnel of the present utility model, comprise tunnel main body 10, tunnel main body 10 has the Tunnel-hole of rectangle, is provided with the pavement 12 of protrusion on the bottom surface of Tunnel-hole.The utility model is set to rectangle by Tunnel-hole, conveniently arrange cable and inspection and maintenance cable, and be provided with the pavement of protrusion in the bottom surface of Tunnel-hole, make things convenient for the maintainer to walk at tunnel internal.The bottom surface that pavement 12 protrudes Tunnel-hole can prevent that also a small amount of ponding is to the inconvenience of overhauling and the laying personnel causes.
Preferably, in Tunnel-hole inside cable support 11 is set, thereby is convenient to lay cable, and cable support can the multilayer setting, thereby improve the utilization rate of tunnel space.In order to make cable support fixing more reliable, can be on the sidewall of Tunnel-hole pre-buried hold-down screw, and cable support 11 is fixed on the pre-buried hold-down screw, thereby improves the reliability of cable support 11.Cable support 11 is arranged on the two side of Tunnel-hole symmetrically, makes the efficient that cable laying is more neat, can improve inspection and overhaul.
Tunnel main body 10 adopts reinforced concrete structure, and the end face of Tunnel-hole and the corner of sidewall have chamfering 13, are conducive to improve the structural strength of tunnel integral body.And be provided with concrete cushion 20 in tunnel main body 10 bottoms, prevent setting of ground and cause 10 structural deteriorations of tunnel main body, the safety that has improved to a certain extent the tunnel.
As can be seen from the above description, the utility model the above embodiments have realized following technique effect:
According to cast-in-place electric power tunnel of the present utility model, be set to rectangle by Tunnel-hole, conveniently arrange cable and inspection and maintenance cable, and be provided with the pavement of protrusion in the bottom surface of Tunnel-hole, make things convenient for the maintainer to walk at tunnel internal.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
