Further, the domatic gradient of described draining is 1.5% to 2%.
Further, the domatic gradient of described draining is 2%.
Further, described water inlet pipe tilts to collecting well direction, and its gradient is 2.6%.
Further, also comprise the casting iron well lid for sealing collecting well, the top of described collecting well is provided with concrete bears down on one, and described casting iron well lid is arranged on concrete bears down on one.
Further, on described concrete bears down on one, be also provided with cast iron support, described casting iron well lid is arranged on cast iron support.
Further, the bottom of described collecting well is provided with the outlet pipe being communicated with municipal Storm Sewer Network.
Further, on described outlet pipe, be provided with flap valve.
The beneficial effects of the utility model are: the one gradient formula transformer station raceway groove drainage system that catchments that the utility model adopts, by collecting well, water inlet pipe being set and arranging in the bottom of cable trench well that to have the draining of certain slope domatic, ponding in cable trench well can be domatic by draining, water inlet pipe is arranged in collecting well, can solve well the problem of transformer station's internal drainage, and the transformer station of can not flowing backwards back, has ensured the safe operation of station cable, electric fixtures.The utility model just can quickly and reliably not discharged ponding by the restriction of the conditions such as ponding, human factor, weather, and its safety, actual effect, flexibility, economy are higher.
Brief description of the drawings
Below in conjunction with accompanying drawing and example, the utility model is described in further detail.
Fig. 1 is front view cross-sectional view of the present utility model.
Detailed description of the invention
Shown in Fig. 1, the one of the present utility model gradient formula transformer station raceway groove drainage system that catchments, comprise cable trench well 1, described cable trench well 1 comprises the body of wall 11 of both sides, the trench cover 12 at top and the concrete floor 13 of bottom, on the body of wall 11 of described cable trench well 1 both sides, be provided with multiple cable steel brackets 14 for carrying cable, on the top of described both sides body of wall 11, be provided with ditch well concrete and bear down on one 15, ditch well concrete bears down on one on 15 and is formed with tongue and groove 16, described trench cover 12 is positioned on tongue and groove 16, also comprise a collecting well 2, the bottom of described collecting well 2 is lower than concrete floor 13, also comprise a water inlet pipe 3, one end of described water inlet pipe 3 is through the borehole wall of collecting well 2, the other end is arranged at the bottom of cable trench well 1 through concrete floor 13, the bottom of described cable trench well 1 is provided with the draining domatic 17 of tilting to water inlet pipe 3 directions.
The utility model arranges the draining domatic 17 with certain slope by collecting well 2, water inlet pipe 3 and the bottom at cable trench well 1 are set, ponding in cable trench well 1 can be domatic 17 by draining, water inlet pipe 3 is arranged in collecting well 2, can solve well the problem of transformer station's internal drainage, and the transformer station of can not flowing backwards back, has ensured the safe operation of station cable, electric fixtures.The utility model just can quickly and reliably not discharged ponding by the restriction of the conditions such as ponding, human factor, weather, and its safety, actual effect, flexibility, economy are higher
Further, the general gradient of described draining domatic 17 is 1.5% to 2%.The preferred slope of draining domatic 17 is 2%.The draining rapidly of the gradient of this design, standing can not affect again constructor and construct time.
Further, described water inlet pipe 3 tilts to collecting well 2 directions, and its gradient is 2.6%.This design can prevent water inlet pipe 3 internal water accumulations, and water inlet pipe 3 can be discharged to the ponding in cable trench well 1 in collecting well 2 rapidly.
