Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the concrete profile of circular pipe.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Prefabricated culvert pipe cable trough is mainly used in the cable trough design of power industry transformer station and current conversion station, mainly to be applicable to the larger region in place, Gobi desert or cold district and dust storm use, for site local climate feature, a kind of prefabricated culvert pipe cable trough is proposed innovatively, be totally enclosed type round cable tunnel, this structure specific embodiments is as follows:
Please refer to shown in Fig. 1: utilize prefabricated reinforced concrete culvert pipe (No. 1 member) to make cable trough, adopt the circular pipe (can utilize prefabricated reinforced concrete drainage pipe) of 1.4m～2.0m internal diameter, 4m～6m segmentation, reinforced concrete segment adopts batch production processing, on-the-spot splicing, adopts tongue and groove pipe rubber ring interface; Cross road section and adopt heavy-duty steel reinforced concrete pipeline section, meet the current requirement of heavy vehicle in station.
In the middle of prefabricated culvert pipe cable trough, high spatial is as personnel's operation and the transit passage of cable laying, laying aisle, bottom, and convenient current, aisle is used for cable trough draining with the space at the pipe end, and the compactness in practical function space, harmony, be shown in Fig. 1.
Prefabricated culvert pipe cable trough both sides adopt the cable bearer (No. 2 members) of unequal length, for cabling; Top, cable tunnel arranges emergency lighting (No. 3 members), facilitates operating maintenance and regular maintenance, sees Fig. 1.
Prefabricated culvert pipe cable trough is direct burial, every 40～60m, armored concrete cable trough inspection shaft and Multilateral Wells is set, and is convenient to installation, operating maintenance and regular maintenance and safeguards.
Prefabricated culvert pipe cable trough basis can adopt subsoil, basis adopts sandstone basis, for example bore designs according to 1400mm, thickness of pipe wall 150mm, C1=300mm, C2=600mm, the pipeline bearing capacity that should be laid in reaches the ground of Pipeline Ground bearing strength requirement, sandstone basis adopts prototype gradation sandstone according to field condition, and its maximum particle diameter should not be greater than 25mm.
Prefabricated culvert pipe cable trough utilizes prefabricated reinforced concrete drainage pipe, on-the-spot installation adopts bell and spigot and tongue and groove pipe rubber ring interface, bell and spigot and flexible tongue and groove are because of its interface employing seal with elastometic washer sealing, to flexibly connect, anti-seismic performance is good, can effectively resist uneven settlement of foundation, and installation rate is favored by user soon and deeply.Pipe more than DN1400 bore, interface should adopt flexible tongue and groove.
