In the weak intelligent residential outdoor wiring design of the people (hand) hole is selected, the first problem is to choose the traditional design way (hand) hole, its mass, is not convenient to use in the intelligent residential district, this is because the developers in order to improve land utilization, to build more the house on the limited land, which can provide various professional laying underground pipeline intelligent residential district location within a relatively narrow, and the pipeline of the professional species and large number of Sugai Me, the comprehensive construction difficult heavy pipe.

Battle, fight depth It is often seen., an obvious problem is designed according to the national standard drawing 94, X 102 "underground communication cable" the big hole volume, even with the small manhole length x width is 3M by 2m, of which two people (hand) wall hole the thickness accounted for 0.98M, of course, we can in the engineering practice with reinforced concrete wall instead of brick walls can greatly reduce the length of nearly LM, thereby reducing the volume of a part, can usually be reduced to each wall thickness O.12-0.16m, the cast-in-place reinforced concrete wall is brick wall 1/3. (this is nonstandard design, not recommended).

In addition, we further analyze why Chinese people (hand) hole volume so large, we use the original general atlas was originally designed for outdoor telephone cable laying and design, it can be suitable for the large number of copper telephone cables, for the thousands of people wearing capacity even thousands of cable continue, can also provide a large number of cables in the manhole (which requires in (hand) hole has a lot of space).

But weak in intelligent residential district outdoor wiring design, we are facing many of the intelligent system of cable, not just a telephone cable, but also some large log phone cables, but more, is a diameter of not more than 20mm of all kinds of cables, for larger diameter telephone cable.

Because we use the way of wiring wiring transfer (direct wiring of the handover from the property center room to the transfer of direct telephone cable laying wiring area for more than 400 to 500, and 600 pair of cables, and its diameter is not too big, and we can try to do without telephone cable connection in the hole (or branch in the use of SK series hand hole, because of the special structure, the hand hole cable can be followed by a subsequent lead hand hole hole in the ground and then put back after jointing), there is no need to (hand) holes require a larger space. As for the small wire diameter cable and fiber cable, in relatively narrow space more adapt.

Therefore, we concluded that the intelligent community of the outdoor weak people in the design of wiring (hand) hole selection, it is feasible to reduce the use of specification, can be used by people who (hand) than the traditional approach of Kong Bian (hand) hole in the volume decreased, decreased investment.

Concrete practice:

You will X 102 GB atlas 94 "underground communication cable laying in the manhole hand hole through the trumpet;

The original small turning manhole, manhole, small differences trumpet trumpet through the fan type manhole manhole replacement;

The for the important parts, such as the "bureau" (Property Center Room) trunk turning previous hole, large amount of cables or three links, four links should still use the traditional way of manhole, shall not reduce the specifications;

The trumpet for the use of straight through manhole parts, even the corresponding hand hole using small turning manhole, manhole, small differences trumpet fan type manhole places still available YD5062 national communications industry standard "communication cable wiring pipeline atlas" in place, such as one or two and three holes (SKl, SK2, the SK3)

The little hole advocated using YD5062-98 graph provided by (SSK), the small hand hole volume minimum clearance area, 0.5X0.4m2, depth is 0.3-0.7m, which can be widely used in the hand hole of multi-storey residential building construction. The introduction of cable can be directly arranged close to the cell door a few meters. The position, so you can easily introduce cable the building, while reducing the amount of steel into the building. (as for the communication pipeline manhole and tube block group YDl 101 Atlas) provided by the manhole is the main for large manhole municipal roads, not often used in the area, but not necessarily, such as property center room of the former Bureau of wells well, the trunk line may also listed on the atlas medium using this manhole manhole, in addition to the benefits of the large body of wire outside, there is the cover plate is prefabricated, on the market to buy.

In 94, X102 and YD5062, the application of -98 to the two sets of right and proper, it is necessary to carefully analyze and study a series of two people (hand) structure characteristics and application range of holes. In general, 94, for the X102 Atlas of the trunk road cabling on the cable quantity in these parts large pipes can be in a relatively large range of adjustment of the depth, the depth can be adjusted to the surface to the depth of well cover is realized through adjusting, also can be adjusted by the length of the wall extended. YD5062, -98 atlas for shallow buried pipe District branch or branch pipe, cable less where the hand hole series of shallow buried pipe, the pipe depth adjustment ability is small, when the need to lengthen the wall depth of some length, increase the bottom plate depth.YD5062, the square - 98 series covers special Special structure, in some provinces and cities are still difficult to buy.

Some of the residential landscape of the park requires high, YD5062, -98 plots of square covers, large green space, the impact of the park green
