Matter is preferable.Analyzed with reference to type and the purposes of anchor, the AC-14 type anchors in high holding power anchor, have stabilising fin it is thick and solid and roomy, to each
Kind of substrate it is adaptable, nibble it is native it is rapid, grab that bottom stability is good and holding power to weight ratio height (value 12~14), also, AC-14 types are big
The grip of grip anchor is at least the common patent anchor of equivalent weight more than twice.To sum up, grip mechanism 30 described in the present embodiment is preferred
For the AC-14 types anchor (as shown in Figure 3) in high holding power anchor.
The present embodiment super-large diameter single-pile foundation horizontally loading test method, includes the following steps：
Step 1：Tensile machine 20 on the pile body 10 is set, hoist engine is preferably mounted on to the top of the pile body 10
Portion；
Step 2：Grip mechanism 30, the AC-14 type anchors being preferably provided in high holding power anchor are set outside the pile body 10；
Step 3：Install pulley assembly, one end of the first section anchor cable is fixedly connected with the hoist engine, the other end and
The pulley assembly is fixedly connected；The interlude anchor cable is set around the pulley assembly；By the one of the latter end anchor cable
End is fixedly connected with the pulley assembly, and the other end is fixedly connected with the high holding power anchor.
In above-mentioned steps three, to set there are four the embodiments of movable pulley 40 to be specifically described：
In the present embodiment, four movable pulleys are named as the first movable pulley, second movable pulley, third and move successively
Pulley and the 4th movable pulley, the interlude anchor cable being corresponding in turn to the movable pulley entitled first interlude anchor successively
Rope, the second interlude anchor cable and third interlude anchor cable, are named as successively with the column that the movable pulley is corresponding in turn to
First column, the second column, third column and the 4th column.
One end of the first section anchor cable is fixedly mounted on the hoist engine, intermediate portion wind the fixed pulley and
First movable pulley is set, and the other end is fixedly mounted on the first column；One end of the first interlude anchor cable is fixed on
It on two columns, is set successively around the fixed pulley and the second movable pulley, the other end is fixedly mounted in the first movable pulley
In mandrel；One end of the second interlude anchor cable is fixed on third column, bypasses the fixed pulley and third successively
Movable pulley is set, and the other end is fixedly mounted on the central shaft of the second movable pulley；One end of the third interlude anchor cable is consolidated
