Description

New earth anchor

Technical field

The present invention relates to the realm of building construction, particularly to a kind of new earth anchor.

Background technology

In construction site, need anchor that the equipment that some set up temporarily is anchored more, steady to ensure it Fixed work it is ensured that operational security, such as, in order to transport material up and down, need to set up derrick, when derrick sets up too high at the scene Need to arrange cable rope its steady operation of drawknot guarantee, and cable rope and ground connecting portion are accomplished by by ground anchorage Realize.In prior art, common are cluster earth anchor, fine rod-type earth anchor and spiral earth anchor, these ground anchor structures are usual Typically have no problem under state, be capable of the purpose of protection equipment steady operation, but when run into wind load excessive or other During load action, ground anchorage can produce in the presence of external loads and rock and so that anchoring dynamics dies down, when serious even Ground anchorage is integrally pulled out, the anchoring complete failure to equipment, even can cause security incident when dangerous

Accordingly, it would be desirable to existing new earth anchor is improved so as to have preferable performance can resist wind load or The vibration that other loads produce is it is ensured that anchoring consolidates power.

Content of the invention

In view of this, the present invention provides a kind of new earth anchor, and it has preferable performance and can resist wind load or other The vibration that load produces is it is ensured that anchoring consolidates power.
