The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, referring to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.
The water of the utility model embodiment anchor pole that rises is at the water anchor pole that rises the pull-out test interface to be set, and described pull-out test interface is the big envelope with connector; By having the supporting connector that links tool that cooperates with described connector, the described 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, and the below gives some instances:
Embodiment one
As shown in Figure 2, the water of the utility model embodiment one anchor pole that rises comprises:
Wherein to water filling interface 5, anchor bar body 7 and underseal 8 the utility model do not improve, and can adopt existing techniques in realizing, repeat no more here.
Wherein, be provided with screw thread 9 outside the big envelope 6, this screw thread 9 is connector, and by this screw thread 9, anchor pole can be connected with puller system by threaded engagement easily so that water rises.
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 utility model also provides and the water of the embodiment one supporting connector that anchor pole cooperates that rises, as shown in Figure 4, this supporting connector 10 be provided with water rise connector on the big envelope 6 of anchor pole be screw thread 9 cooperate be connected tool be internal thread 11(owing to cooperating, screw thread 9 overlaps with internal thread 11 among the figure); 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 for connecting 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 by the supporting chain joint 10 of cutting ferrule 14 and this.
In addition, as another embodiment, as shown in Figure 5, through hole on this supporting chain joint 10 12 is interior can also to be provided with internal thread 25, is connected by the external screw thread with puller system the axis of the piston 13 or similar syndeton.
