Problems solved by technology

In order to optimize the design of the steel pipe tower foundation, a method of quantitatively testing the overturning moment is necessary, but the official test standards from ASTM, KS, etc. only have test standards related to the main loads of the overall independent foundation such as vertical load and horizontal load
That is, no standardized test method has been established for testing overturning moments

Abstract

The invention discloses a base moment test device of a transmission tower of a steel pipe support. The device can exert load to a top of a protruded structure on the ground in a horizontal or inclining direction; supporting performances of the base and the ground are analyzed according to the load and the depth so as to gain a value relative to the moment of the protruded structure on the ground and ensure exact design and safe use.

Description

technical field [0001] The invention relates to a foundation moment testing device for a steel pipe prop transmission tower. More specifically, the present invention relates to a foundation moment testing device, which can analyze the support performance of the foundation and the ground according to the load and depth by applying a load to the top of a protruding structure on the ground in a horizontal or inclined direction to obtain a relationship with the ground The value related to the moment of the protruding structure on the surface, so as to ensure the accuracy of the design and the safety of use. Background technique [0002] Construction of high-voltage transmission lines has been steadily increasing as electricity demand rises. However, the lattice tower foundation, which occupies most of the foundation and structural design of the transmission tower, has problems such as high construction cost, excessive deforestation, and high repair cost due to its large constru...
