Description
Technical Field
The utility model relates to a cable pit drainage technology field, concrete field is a fill husky cable pit drainage system.
Background
The 220kV and 500kV cable is widely applied to thermal power plants, especially gas turbine generator power plants. The 220kV and 500kV cable laying mode mainly comprises a cable tunnel and a sand-filled cable trench, the cable tunnel is mainly used in an urban comprehensive pipe gallery and is high in investment and operation cost, the sand-filled cable trench is mainly adopted in a power plant, the conventional sand-filled cable trench is usually buried in an underground unsealed trench, the periphery of a cable is filled with yellow sand, rainwater permeates into the sand-filled cable trench through gaps of the ground surface and a trench cover plate, a plurality of drain holes are arranged at the bottom or in the lateral direction of the sand-filled cable trench, and the drain holes are formedThe outer part is provided with 0.3m multiplied by 0.3m broken stones, and accumulated water in the sand-filled cable trench is drained in a permeating way. Since this drainage is point-type permeate drainage, each permeate drainage point can provide a permeate area of only 0.45m2The seepage drainage speed and the drainage quantity are very limited, if a seepage drainage port is arranged at the bottom of the trench, the soil compaction degree at the bottom of the trench is 0.94, the seepage drainage is more difficult, and the phenomenon of water accumulation exists in part of engineering sand-filled cable trenches, so that the safe operation of the cable is influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a fill husky cable pit drainage system to fill easy ponding in the husky cable pit among the solution prior art, the drainage is not smooth, influences the problem of cable safe operation.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a fill husky cable pit drainage system, every hole fills husky cable pit's interior is arranged a diameter 100 mm's vertical soft pipe of permeating water, fills husky cable pit bottom every 30m and has arranged a diameter 100 mm's horizontal soft pipe of permeating water, and horizontal soft pipe of permeating water and vertical soft pipe of permeating water pass through three way connection intercommunication, the tip introduction sewer of horizontal soft pipe of permeating water.
Preferably, fill husky cable pit bottom and be equipped with the rubble bed course of permeating water, rubble permeate water the hole of leaving diameter 150mm, interval 500mm between rubble permeate water the bed course and fill husky cable pit in advance.
Preferably, the thickness of the gravel permeable cushion layer is 100 mm.
Compared with the prior art, the beneficial effects of the utility model are that: the soft water permeable pipe is arranged in the sand-filled cable trench, so that the good permeability, filtering performance and quick drainage of the soft water permeable pipe can be fully exerted, and accumulated water in the sand-filled cable trench is quickly drained into a rainwater sewer; a gravel permeable cushion layer is arranged below the sand-filled cable trench, so that point type water seepage at the bottom of the trench is changed into surface type water seepage, the water seepage area at the bottom of the trench is enlarged, and meanwhile, water in the trench permeates to the two sides of the trench, and drainage of the sand-filled cable trench is further guaranteed.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a structural sectional view of the present invention.
In the figure: 1 longitudinal soft water permeable pipe, 2 transverse soft water permeable pipe, 3 broken stone water permeable cushion layer and 4 broken stone water permeable holes.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a fill husky cable pit drainage system, every hole fills husky cable pit's interior has arranged a vertical soft formula pipe 1 that permeates water of diameter 100mm, fill husky cable pit inner bottom has arranged a horizontal soft formula pipe 2 that permeates water of diameter 100mm every 30m, horizontal soft formula pipe 2 that permeates water communicates through three way connection with vertical soft formula pipe 1 that permeates water, the tip of horizontal soft formula pipe 2 that permeates water is introduced into the sewer, soft formula pipe that permeates water is a tubular product that has infiltration, filtration, drainage effect, its pipe wall from inside to outside material is respectively for covering PVC high carbon steel wire spiral skeleton, non-woven fabrics filter layer and synthetic polyester fibre outward, the rainwater is through surface soil, the gap of ditch apron, the infiltration of yellow sand in the ditch, vertical soft formula pipe 1 that permeates water and filters and horizontal soft formula pipe 2 that permeates water drains to the sewer, can effectively get rid of the interior water conservation of ditch, prevent the interior yellow sand loss of ditch.
Preferably, fill husky cable pit bottom and be equipped with the rubble bed course 3 that permeates water that the thickness is 100mm, rubble permeate water between rubble permeate water bed course 3 and the fill husky cable pit and reserve the rubble hole 4 that permeates water of diameter 150mm, interval 500mm, rainwater is through surface soil, ditch apron gap, infiltration of yellow sand in the ditch, circular shape rubble hole 4 that permeates water, rubble permeate water bed course 3, ditch bottom and side soil infiltration, in addition, rubble permeate water bed course 3 in this embodiment is the channel bed course, need not to increase engineering cost.
The application provides a fill husky cable pit drainage system's drainage flow:
rainwater → surface soil → gap of cover plate of ditch → infiltration of yellow sand in ditch → infiltration and filtration of longitudinal soft water permeable pipe, drainage of transverse soft water permeable pipe → sewer to rainwater;
rainwater → surface soil → gap of cover plate of ditch → infiltration of yellow sand in ditch → permeable hole for broken stone → permeable cushion layer for broken stone → infiltration of soil at bottom and side of ditch.
According to the drainage system of the sand-filled cable trench, the soft water permeable pipe is arranged in the sand-filled cable trench, so that the good permeability, filtering performance and quick drainage performance of the soft water permeable pipe can be fully exerted, and accumulated water in the sand-filled cable trench is quickly drained into a rainwater sewer; a gravel permeable cushion layer is arranged below the sand-filled cable trench, so that point type water seepage at the bottom of the trench is changed into surface type water seepage, the water seepage area at the bottom of the trench is enlarged, and meanwhile, water in the trench permeates to the two sides of the trench, and drainage of the sand-filled cable trench is further guaranteed.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
