Problems solved by technology
If the cover is not opened in time for ventilation, the relative humidity in the cable trench will be high, which will seriously affect the heat dissipation function of the cable
The heat generated by the cable cannot be dissipated in the humid air in the cable trench, which reduces the insulation of the cable
It will reduce the service life of the cable. If the cable is immersed in water, it will also cause equipment failure, which will cause major consequences in water conservancy and hydropower projects.
At this time, the leakage power increases sharply, which is likely to cause a fire
Therefore, after the rainy weather, the staff need to go to the site to manually check and complete the manual drainage, which consumes manpower and material resources, high cost and low efficiency

Embodiment Construction
[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0013] A kind of quick drainage cable channel structure of the present invention, as figure 1 As shown, the cable ditch 1, the bottom surface of the cable ditch 1 is a slope 7 with high sides and low middle, the lowest part of the slope 7 is provided with a drainage ditch 8, the bottom of the drainage ditch 8 is provided with a drain pipe 9, and the entrance of the drain pipe 9 is Floor drain 10 is provided. A pre-embedded angle steel 4 is provided at the connection groove 3 between the cable trench 1 and the cover plate 2 . The bottom surface of the pre-embedded angle steel 4 is welded with tie bars 5, and the tie bars 5 extend into the concrete 6 on both side walls of the cable trench 1. The tie bar 5 is L-shaped, and the tie bar 5 is connected with the reinforcing bars in the concrete 6 on both side walls of the cable trench 1 .

The invention discloses a rapid-draining cable trench structure. The structure comprises a cable trench (1), wherein the bottom surface of the cable trench (1) is a slope surface (7) with high two sides and low middle part, a drainage trench (8) is arranged on the lowest position of the slope surface (7), a drainage pipe (9) is arranged at the bottom of the drainage trench (8), and a floor drain (10) is arranged at an inlet of the drainage pipe (9). The structure is simple and convenient to construct. Tie bars are arranged on the lower edge of a cover plate, and the defect that the edge of thestructure is prone to tension fracture under stress is overcome; by means of the bottom slope of the cable trench and the drainage trench, seeping water can be rapidly concentrated and collected, andthe defects of time and energy waste, high investment and low efficiency caused by need of manual ponding check and artificial drainage after raining are overcome.
Description
technical field [0001] The invention relates to a fast drainage cable ditch structure, which belongs to the technical field of building construction. Background technique [0002] Existing cable trench structures mostly use rectangular cross-sections in water conservancy and hydropower projects and are used in outdoor environments such as dam crests. Considering the aesthetic requirements in the outdoor access area, the cover plate is mostly kept at the same level as the ground. In addition to rainy and snowy weather, ground water accumulation in water conservancy and hydropower projects is more serious. When the cover plate is not tightly sealed, water accumulation is easily generated in the cable trench. If the cover is not opened in time to ventilate, the relative humidity in the cable trench will be high, which will seriously affect the heat dissipation function of the cable. The heat generated by the cable cannot be dissipated in the humid air in the cable trench, whi...
