Detailed Description
The invention is further described with reference to the following figures and detailed description.
As shown in fig. 1 to 4, the cable and drainage system for the riverbed type workshop dam crest of the hydropower station comprises a cable and drainage gallery 1, an illuminating cable trench 2, a tail water hoist cable trench 3, a gallery access passage 4 and a drainage system 5, wherein the cable and drainage gallery 1 is a gallery structure arranged in concrete at the workshop dam crest, and the cable and drainage gallery 1 is communicated with the outside through a cable inlet 13 and a cable outlet 14 for wiring; the lighting cable trench 2 and the tail water hoist cable trench 3 are respectively communicated with the cable and the drainage gallery 1 for wiring; a pedestrian and drainage channel 11 and a cable channel 12 are arranged in the cable and drainage gallery 1, the cable channel 12 is a groove structure arranged on the side wall of the pedestrian and drainage channel 11, and the bottom plate of a groove corresponding to the cable channel 12 is higher than the bottom plate of the pedestrian and drainage channel 11; the gallery access passage 4 is communicated with the cable and drainage gallery 1; and ditch water discharge systems 5 are respectively arranged in the cable and drainage gallery 1, the lighting cable ditch 2 and the tail water hoist cable ditch 3.
The cable and drainage gallery 1 is set to be a gallery structure in concrete of the dam crest of the factory building to replace a traditional open trench type with a concrete cover plate, and the pedestrian and drainage channel 11 and the cable channel 12 are arranged in the gallery according to functions in a partitioned manner, so that the large-span open trench type is prevented from occupying the traffic space of the dam crest, the later operation and maintenance are facilitated, and the attractive effect of the dam crest is improved. Of course, the specific cables and drainage galleries 1 may be distributed according to actual conditions, as shown in fig. 1, and the cables and drainage galleries 1 are arranged in a "door" shape as a whole, that is, the cross section of each cable and drainage gallery 1 is substantially in the shape of a "door" frame. Meanwhile, due to the requirement of cable arrangement, two cable inlets 13 and two cable outlets 14 can be specifically arranged, and specific positions can be specifically arranged according to the needs of passing in and out the wiring, such as the positions shown in the attached drawing 1, so that the wiring can be communicated with the adjacent dam sections on the two sides of the plant. Of course, without loss of generality, as for the specific number of the cable inlets 13 and the cable outlets 14, more number can be provided as required, and the number can be arranged according to the requirement of the in-out wiring. As shown in fig. 1, the cable of the present invention runs as follows: the cable and the drainage gallery 1 are led out from the cable inlet 13, led out to dam sections at two sides of the factory building through the cable and the drainage gallery 1 vertical to the water flow direction and the cable outlet 14, and communicated with the upstream and downstream lighting cable trench 2 and the tail water hoist cable trench 3 through the cable and the drainage gallery 1 along the water flow direction.
In addition, the interior of the cable and drainage gallery 1 is divided into two parts, namely a pedestrian and drainage channel 11 with a lower floor elevation and a cable channel 12 with a slightly higher floor elevation, according to functional partitions; therefore, the pedestrian can conveniently pass and drain, the arrangement effect of the cable and the drainage gallery 1 is improved, and the cable is convenient to walk and overhaul. Referring to fig. 2, the cable channel 12 is formed as a step structure provided on the side wall of the pedestrian and drainage channel 11. Of course, the specific dimensions of the pedestrian and drainage channel 11 and the cable channel 12 should be reasonably set according to the actual pedestrian traffic requirements and the installation requirements of the wiring without loss of generality.
In the invention, the cable and drainage gallery 1 is a main channel for cable routing, and the lighting cable trench 2 and the tail water hoist cable trench 3 are local routing structures corresponding to actual functional partitions in the plant. The lighting cable trench 2 and the tail water hoist cable trench 3 are wired in a traditional open trench mode, and the lighting cable trench 2 and the tail water hoist cable trench 3 belong to local structures and are very small in wiring amount, so that a relatively small open trench mode is adopted; of course, without losing generality, the cable and drainage gallery 1 needs to be communicated with the cable and drainage gallery through the lighting cable trench 2 and the tail water hoist cable trench 3 so as to realize connection and routing from the cable and drainage gallery 1.

The gallery service passage 4 is arranged to facilitate entry into the cable and drain gallery 1 through the gallery service passage 4 for corresponding service. Of course, the arrangement of the gallery service passages 4 at intervals can facilitate direct entry into the cables and the drainage galleries 1 at different positions, so as to facilitate quick development of cable service, drainage and dredging.
The drainage system 5 is used for draining accumulated water generated in the cable and drainage gallery 1, the lighting cable trench 2 and the tail water hoist cable trench 3 to the outside of a factory. Specifically, the drainage system 5 can be arranged at regular intervals along the respective trends of the cable and drainage gallery 1, the lighting cable trench 2 and the tail water hoist cable trench 3. The drainage system 5 may specifically include a drainage pipe 51, one end of the drainage pipe 51 is connected to the bottom of the cable and drain gallery 1, the lighting cable channel 2 and the tail water hoist cable channel 3, and one end of the drainage pipe 51 extends to the outside of the factory building.
