Abstract
The utility model discloses an underground cable channel structure. The underground cable channel structure comprises the ground (3), a stone cushion layer (8), a cement cushion layer (7) and the wall (6); the stone cushion layer (8) is arranged under the ground (3); the cement cushion layer (7) is arranged above the stone cushion layer (8); a channel (10) is arranged above the cement cushion layer (7). The underground cable channel structure is characterized in that the channel (10) is in a rectangular structure integrally; the periphery of the channel (10) is provided with the wall (5); a flexible cover plate (2) is arranged at the top of the channel (10); the interior of the all (6) is provided with reinforcement bars; cable conduits (9), optical cable conduits (11) and backflow cable conduits (4) are arranged inside the channel (10). The underground cable channel structure has the advantages of being simple in structure and reasonable in design and having broad market prospects.
Description
Technical field
The utility model relates to a kind of channel design, and especially a kind of underground cable channel design, belongs to technical field of civil engineering.
Background technology
At present, the cable of conveying high-pressure electricity is in order to save limited land area, reduce construction cost, all to adopt underground passage transmission of electricity, yet current underground transmission passage has following shortcoming: 1, can not prevent fires, once cable external insulation is damaged, can cause electric leakage, also can produce spark, make breaking out of fire in passage; 2, passage both sides are non-watertight, and long-time passage internal water accumulation is serious, and cable is immersed in water, causes erosion damage; 3, channel function is single, the cable of only switching on, and obstructed All other routes, cause the wasting of resources.
Summary of the invention
The purpose of this utility model is to provide a kind of underground cable channel design.
Problem to be solved in the utility model be existing underground cable passage can not fire prevention, the defect of waterproof and function singleness.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of underground cable channel design, comprise stone bed course, cement bed course and body of wall, described stone bed course is located at below ground, cement bed course is located at stone bed course top, cement bed course top is provided with passage, it is characterized in that: described passage is whole is rectangle structure, and surrounding is provided with body of wall, top is placed with removable cover, and body of wall inside is provided with reinforcing bar; In described passage, be provided with cable conduit, cable tube and backflow cable pipe.
Described cable conduit, is provided with sand between cable tube and backflow cable pipe.
Described removable cover is concordant with ground.
Described body of wall both sides external is also provided with waterproofing course.
The utility model has the advantages that: by be provided with sand between cable conduit, in passage both sides, be provided with waterproofing course again, sand is by between each cable conduit, intercept between cable conduit and air, waterproofing course every outside at cable passage, has solved that existing cable passage can not be prevented fires, the problem of waterproof by water resistance effectively.Again at the inner All other routes passage that increases of cable passage, avoided the waste in space simultaneously, provided cost savings.The utlity model has advantage simple in structure, reasonable in design, there are wide market prospects.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model underground cable channel design.
In figure: 1, sand, 2, removable cover, 3, ground, 4, backflow cable pipe, 5, body of wall, 6, reinforcing bar, 7, cement bed course, 8, stone bed course, 9, cable conduit, 10, passage, 11, cable tube, 12, waterproofing course.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, the utility model underground cable channel design, comprise stone bed course 8, cement bed course 7 and body of wall 6, described stone bed course 8 is located at 3 belows, ground, and cement bed course 7 is located at stone bed course 8 tops, cement bed course 7 tops are provided with path 10, described path 10 integral body is rectangle structure, and surrounding is provided with body of wall 5, and top is placed with removable cover 2, body of wall 5 inside are provided with reinforcing bar 6 and are used for strengthening body of wall 6 structural strengths, prevent landslide; In described path 10, be provided with cable conduit 9, cable tube 11 and backflow cable pipe 4.
Cable conduit 9, between cable tube 11 and backflow cable pipe 4, be provided with sand 1, removable cover 2 is concordant with ground 3 feels Uneven road when so can not allow vehicle and pedestrian pass through, and body of wall 5 both sides external are also provided with waterproofing course 12 water of cable passage both sides is blocked, and prevent from infiltrating path 10 inside.
After treating that body of wall 6 is built up, by cable conduit 9, cable tube 11 and backflow cable pipe 4 are placed on respectively path 10 inside, through different pipelines, sand 1 is poured to the cable of different circuits into path 10 inside, make cable conduit 9, between cable tube 11 and backflow cable pipe 4, by sand 1, separated, reach sealing effectiveness with air next door, therefore can not produce fire, finally cover removable cover 2 simultaneously.
Claims (4)
