The specific embodiment
For making the object of the invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, to further explain of the present invention.
The anchor pole method of attachment of rising of the water of the embodiment of the invention is that the pull-out test interface is set on water rises by anchor pole, and said pull-out test interface is the big envelope with connector; Through having the supporting connector that links tool that cooperates with said connector, the said water anchor pole that rises is connected with puller system.
Connector on the big envelope can adopt the connector of any on-fixed type of attachment, gives some instances below:
Embodiment one
As shown in Figure 2, the water of the embodiment of the invention one anchor pole that rises comprises:
Wherein to water filling interface 5, anchor bar body 7 does not improve with underseal 8 the present invention, can adopt existing techniques in realizing, repeats no more here.
Wherein, big envelope 6 is outer to be provided with screw thread 9, and this screw thread 9 is connector, through this screw thread 9, makes the water anchor pole that rises to be connected with puller system through threaded engagement easily.
The thread type of screw thread 9 is any, for example can be corrugated thread, trapezoidal thread or angular thread.
In order to be connected with puller system; The present invention also provides and the water of the embodiment one supporting connector that anchor pole cooperates that rises; As shown in Figure 4; It is that the tool that is connected that screw thread 9 cooperates is internal thread 11 (owing to cooperate, screw thread 9 overlaps with internal thread 11 among the figure) that this supporting connector 10 is provided with the connector that rises on the big envelope 6 of anchor pole with water; This supporting connector 10 is end sealing; The cylinder that one end is open, its inwall is provided with internal thread 11, is connected with the screw thread 9 of big envelope 6; Also be provided with through hole 12 on the blind end of this supporting chain joint 10, this through hole 12 can be used to connect the axis of the piston 13 or the similar syndeton of puller system; Wherein, puller system the axis of the piston 13 inserts in this through hole 12, is connected through the supporting chain joint 10 of cutting ferrule 14 and this.
In addition, as shown in Figure 5 as another embodiment, can also be provided with internal thread 25 in the through hole 12 on this supporting chain joint 10, be connected through external screw thread with puller system the axis of the piston 13 or similar syndeton.
