Abstract

The utility model relates to a self-pressure tower tube base, wherein the upper portion of the tower tube base is connected with a tower tube, and the tower tube base is provided with a multi-chamber armored concrete box base formed by a top board, a bottom board, a lateral partition wall, a vertical partition wall, an inner tube wall and an outer tube wall, wherein the lower surface of the top board is provided with a bottom module, pressure materials are filled in each chamber, and the inner tube wall and the outer tube wall are in circular shapes or polygonal shapes. The self-pressure tower tube base leads the gravity center of the whole structure to shift down, which has excellent stability, better load-carrying capability and higher rigidity compared with an original independent base, increases horizontal lateral pressure, is beneficial for preventing the base from horizontally moving laterally, reduces the usage of armored concrete, and saves cost. Pressure materials can be used as the bottom module of the top board after flattening and compacting, which not only save materials, but also are convenient for construction, and are more environmental-friendly, and big-volume concrete construction can be changed into small-volume concrete construction, and the self-pressure tower tube base can prevent cracks generated by construction temperature and stress, and is suitable for a wind-driven generator group or tower tube bases of other buildings.

The beneficial effects of the utility model are as follows:

1, the utility model stress performance is better, and rigidity has been improved in more former single footing, has increased horizontal side pressure, helps preventing the horizontal sidesway on basis.

2, the utility model has reduced the steel concrete consumption, has saved cost.

3, adopt the utility model in construction, variable mass concrete construction is the small size concrete construction, and can prevent the crack that construction temperature stress produces.

4, but the bed die of double as top board after the smooth compacting of ballast material in the utility model had both been saved material, was convenient to construction again.

5, the utility model makes the down-shift of working center of total, good stability.

6, the utility model environmental protection more.

The utility model is applicable to the tower barrel base of wind power generating set or other building.
