The construction of buildings is also the laying of cable lines and other communications. Moreover, cable laying, as experts say /KVVG-4X1.5,
A special stage of construction, since it requires accounting for seasonal changes, including changes in air temperature, as well as changes associated with soil and soil. In fact, these conditions are decisive in construction technologies, as well as in the system of organization of work.
For example, in the summer, the KVVG cable 4×1.5 is laid by a tassurous way. This is a fairly quick way, equipment is used such as field cable layers. In the winter, when the soil freezes, the cable is laid in the trench prepared for this. When there are rock conditions, for example, builders of the Sochi Olympics often face rocky soil, the cable fits in an open trench.
At the same time, in the southern, western zones, as well as in central Russia, you can lay the cable year -round, with small changes in the technological process. And in the desert zone/semi -deserts – in winter or spring.
A taiga zone with a marshy element, the tundra and forest -tundra territory are zones when the cable laying is necessary in winter.
If the soil freezes more than 20 cm, then its laying is carried out using a knife cable layer.
As for the temperature regime, in most cases, the ambient temperature should be positive.
