Abstract
The utility model discloses a same tower dual loop linear tower for slope-shaped sections, which can be used in places with greater height differences. The same tower dual loop linear tower for slope-shaped sections comprises the tower body of a lead loop close to the slope side and a lead loop against the slope side. An upper cross-arm, a middle cross-arm and a lower cross-arm are arranged from top to bottom on the tower body. Both the close-slope side and the back-slope side are equipped with independent lattice type steel columns so as to form the tower body. When an iron tower is assembled, shorter steel columns for the independent lattice type steel columns at the close-slope side and longer steel columns for the independent lattice type steel columns at the back-slope side can be chosen. Therefore, the height difference between the tower feet of the independent lattice type steel columns at the close-slope side and the tower feet of the independent lattice type steel columns at the back-slope side can be arbitrarily set according to the requirements of different gradients, so that iron towers can be erected on a gradient with a greater height difference. The above structure has the advantages of clear and reasonable bearing, greater height difference, small occupation area and simple foundation type.

1. this place's iron tower adopts comprehensive unequal leg to arrange the requirement that is difficult to satisfy the gradient, even satisfy reluctantly, also will cause back slope side column foot to expose height H 1 excessive, the earthwork that need increase engineering greatly could expose this height H 1 elimination.
2. by the designing requirement of the lead distance to the ground H2 on the sloping side cross-arm, with making iron tower adopt very high exhaling to claim that high H3 just can meet the demands, very uneconomical.
(the lead distance to the ground: because of electric aspect reason, lead is to the minimum range on ground, must greater than the rules specified minimum value)
The utility model content
