We should rarely carry out construction in the District Park, the construction experience in the park is deficient, I myself summed up my own experience, and share some experience with you today. Inadequacies, please reply to supplement.
In the construction of the park, it is the best way to obtain the construction drawings from the property unit, but some drawings are different from the actual construction conditions.
First of all, when entering the construction site, it is necessary to survey the surrounding construction sites and find some reference materials that can really move the pipeline. The most effective way is to look at the cover of the well. Attention should be paid to construction in a particular place.
1. The gate of the district. This example is very typical.
As you can see from the photos, the cell doors are equipped with cameras and door railing. There are also some underground pipes that enter the park from the gate, so we must pay attention to the construction of the gates. In particular, the concentration of camera line and electric door railing wire is very shallow, generally between 300MM - 500MM.
2. green belt
From the photo, most of the green belts are street lamps, floor lamps and various well covers. From the direction of street lamps and floor lamps, we can see the trend of cables. The depth of the general burial is also very shallow. The manhole cover just needs to be called to see the direction and depth of the pipeline.
3. Entrance of the building unit
Any pipeline is entered at the entrance of the building unit. So all the pipelines in the park are gathered in this place, so construction must be careful. From the photo, there are gas pipelines, including water, electricity, communications, cable TV, heating and so on.
4. communication cable box and substation
It is best to know the direction of the unit concerned. If it is not known, it should be noted all around. Generally speaking, the direction of the communication cable box and the opening of the substation is the direction of the wire going in.
I hope you don't have trouble when you work.
