Abstract

The utility model discloses an independent medium-sized pile foundation. The independent medium-sized pile foundation consists of concrete and reinforcements. Piles (2), which are formed by casting concrete, are arranged below a power transmission line iron tower (1); a reinforcement cage is arranged in each pile (2) and consists of pile main reinforcements, out-pile stirrups, in-pile stirrups, foundation bolts, ground bolt stirrups and a protective plate; the protective plate is welded on the pile main reinforcements; each pile is connected with the iron tower through the corresponding foundation bolts; a protective cap is arranged on each foundation bolt. According to the foundation, the consumption of foundation concrete is reduced, the cubic meter of dug earth and stone of a foundation pit is reduced, the floor space is reduced, the ecological environment is protected, the construction process is simple, and the cost is low.

Description

Independent medium-sized pile foundation

Technical field

The utility model relates to a kind of power transmission line iron tower foundation.

Background technology

At present, the pole and tower foundation of transmission line of electricity is mainly adopted as shallow foundation, and the concrete consumption on conventional basis and the earthwork of excavation of foundation pit are larger, larger to the damage area of farmland or vegetation during construction, a large amount of spoirs have also affected column foot ecological environment around, with the contradiction of environmental requirement.

Utility model content

The purpose of this utility model is to overcome the problems referred to above, and a kind of medium-sized pile foundation of independence of novel environment friendly is provided.

For achieving the above object, the technical solution adopted in the utility model is:

The medium-sized pile foundation of a kind of independence; by concrete, reinforcing bar, formed; it is characterized in that: under steel tower (1), have the stake (2) of pouring concrete; in stake (2), is furnished with reinforcing cage (3); reinforcing cage (3) by the main muscle of stake (6), stake outer stirrup (7), the interior stirrup (8) of stake, stone bolt (5), bolt stirrup (9), backplate (10) form; backplate (10) is welded on the main muscle of stake (6); stake (2) is connected with steel tower (1) by stone bolt (5), has protective cap (4) on stone bolt (5).

The utility model compared with prior art has the following advantages:

1. reduce base concrete consumption.

2. reduce the earthwork of excavation of foundation pit.

3. reduce floor space, preserve the ecological environment.

4. construction technology is simple, and cost is low.
