Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model is furtherd elucidate, it should be understood that these embodiments are only used for
Illustrate the utility model rather than limitation the scope of the utility model, after the utility model has been read, art technology
Modification of the personnel to the various equivalent form of values of the present utility model falls within the application appended claims limited range.
Embodiment 1
As shown in Figures 1 to 3, a kind of externally pre-stressed concrete blower fan pylon hyollow foundation, it includes armored concrete tower
Frame 1, prestress wire 2 and reinforced concrete hollow basis 6；
Described armored concrete pylon 1 is cylindrical；
Basic 6 bottoms of described reinforced concrete hollow are provided with concrete cushion 7, the inner side of reinforced concrete hollow basis 6
Wall top is provided with protrusion ring beam 5, forms inverted T shaped hollow section；
The protrusion ring beam 5 is provided with steel strand wires through hole 3；Steel strand wires through hole 3 is straight hole road or is the hole with curvature
Road.
Prestress wire 2 is located at cylindric reinforced concrete after passing through the steel strand wires through hole 3 on protrusion ring beam 5 from the bottom up
The inner side of native pylon 1, prestress wire 2 applies prestressing force by external post stretching mixes armored concrete pylon 1 with reinforcing bar
The solidifying native connection of hyollow foundation 6 forms entirety, and the bottom of steel strand wires 2 is provided with anchor head 4.
Above-described externally pre-stressed concrete blower fan pylon hyollow foundation, the bottom elevation of protrusion ring beam 5 are located at steel
