Tieback Ground earth anchor system:

In order to determine the suitability of tieback earth anchor in the intended location and to determine design paremeters, a feld testing program was undertaken. A total of fve tiebacks earth anchor were installed at the project site in the initial open cut excavation. The first prototype failed miserably, and this once again led to questioning of the entire system. Upon closer examination, it was determined that the drilling procedure was to blarme; water was used for the drilling and this caused a thin layer of mud to form along the hole. Subsequent prototypes gave the desired results after the drilling procedure was modified. Two of the tests, using the  final configuration of the tieback, yielded a load of 189 kips (840 kN) before failure. This correlated to a bond stress of approximately 33 psi (228 kPa). After the load testing, two of the tiebacks earth anchors were locked off at the design load and monitored for creep for a period of four months. When projected out, this showed a loss of less than 10% in the initial load over a period of 25 years.

Tieback Earth Anchor system:

In the middle of the grape plantation, will put a lot of concrete column, even there are a lot of barbed wire, wire between concrete column is used to grow vines, the vines grow up will be very thick, the weight is very big, concrete column are under a lot of force, which is often not balanced forces, it is easy to make column tilt then collapsed, so with anchor around the post. The role of the Tieback Earth Anchor is to strengthen the column, so that the column increased stability, can withstand greater external forces, so design a vineyard anchor.

The utility model relates to a planting error, more specifically to a Ground anchors for planting vineyards, including concrete substrates. Horizontal reinforcement and vertical Reinforcement can make the column withstand a lot of external forces, at the same time, during installation. When the ground is wrong, the part of the anchor can be leaked out of the ground to reduce the cause.

For the alkaline land and corrosion, at the same time convenient burial. Vertical steel bar the two ends of the bending ring 1 and II: transverse steel and concrete matrix phase connected, and the transverse steel bar is iocated inside the concrete matrix, and the vertical steel bar is connected with the concrete matrix, and the vertical reinforcement bar is located in the concrete matrix Inside, the vertical steel bar is connected with the horizontal steel bar, and the horizontal steel bar passes through Ring II on vertical rebar.
