Abstract
The utility model provides an open cast-in-place power tunnel which comprises a tunnel body provided with a rectangular tunnel hole. The tunnel hole is internally provided with a cable bracket where a cable is paved. According to the open cast-in-place power tunnel provided by the utility model, the tunnel hole is rectangular, so that the cable is convenient to arrange, inspect and maintain, therefore, the utilization ratio of the tunnel space is effectively improved.
Description
Technical field
The utility model relates to the field, tunnel, in particular to a kind of bright cast-in-place electric power tunnel of opening.
Background technology
Common brightly open cast-in-place electric power tunnel form 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 bright space availability ratio of opening 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 cable of conveniently arranging brightly opens cast-in-place electric power tunnel.
The utility model provides a kind of bright cast-in-place electric power tunnel of opening, and comprises the tunnel main body, and the tunnel main body has the Tunnel-hole of rectangle, is 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, be provided with the pavement of protrusion on the bottom surface of Tunnel-hole.
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 the bright cast-in-place electric power tunnel of opening of the present utility model, be set to rectangle by Tunnel-hole, conveniently arrange cable and inspection and maintenance cable, thus effectively improve the utilization rate of tunnel space.
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 according to the bright cross-sectional configuration schematic diagram of opening 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 the bright cast-in-place electric power tunnel of opening of the present utility model, comprise tunnel main body 10, tunnel main body 10 has the Tunnel-hole of rectangle, is provided with the cable support 11 of laying cable in the Tunnel-hole.The utility model is set to rectangle by Tunnel-hole, conveniently arrange cable and inspection and maintenance cable, thus effectively improve the utilization rate of tunnel space.
Preferably, be embedded with hold-down screw at the sidewall of Tunnel-hole, cable support 11 is fixedly installed on the pre-buried hold-down screw.Adopt the mode fixed cable support 11 of pre-buried hold-down screw, can effectively improve the reliability of cable support 11.Cable support 11 is arranged symmetrically with in the two side, thus make cable laying neat, can improve the efficient of inspection and maintenance.
Preferably, be provided with the pavement 12 of protrusion in the bottom surface of Tunnel-hole, the personnel that cause patrol and overhaul inconvenience when preventing from the Tunnel-hole a small amount of ponding being arranged.
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 the bright cast-in-place electric power tunnel of opening of the present utility model, be set to rectangle by Tunnel-hole, conveniently arrange cable and inspection and maintenance cable, thus effectively improve the utilization rate of tunnel space.
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.
