[0021] In order to make the utility model's purpose, technical scheme and advantage more clearly clear, the following combines the drawing and embodiment, and further detailedly explains the utility model.

[0022] For example, Figure 1As shown, the simple reinforcement device for testing the pull-out bearing capacity of pipe piles uses connector 1 and clamp 2 to connect and reinforce the end plate 3 and pipe pile 4. The overall pull-out setting consists of a through-core top, screw rod, flange 5, crossbeams, counterweights, oil pump, and JCQ instrument. Two counterweights are set on both sides of the pipe pile 4, and two crossbeams are set on top of the counterweights. The through-core top is supported on the surface of the two crossbeams. The screw rod is connected to the locking head of the through-core top and extends downward to the top of the pipe pile 4. The flange 5 is fixed at the bottom of the screw rod. The end plate 3 is connected via... The end plate 3 is fixed to the top of the pipe pile 4 by welding or other fixing methods. The reinforcement device is used to reinforce the connection between the end plate 3 and the pipe pile 4. Several screw holes 31 are evenly distributed on the surface of the end plate 3. The flange 5 is vertically connected to the screw holes 31 by screws, and the flange 5 is fixed to the end plate 3 as a whole. The through-core top is connected to the oil pump, and the tensile strength of the through-core top is monitored by the JCQ instrument. The oil pump pressurizes the through-core top, so that the locking head transmits the force given by the through-core top to the screw rod. The screw rod drives the lower flange 5 to pull upward, which is used to carry out the tensile test on the pipe pile 4.

[0023] Example 1: As Figure 2 , Figure 4 As shown, several L-shaped connectors 1 are evenly distributed around the end plate 3. The top horizontal part of the connector 1 is flat against the surface of the end plate 3 and is staggered with the screw hole 31. The vertical part of the connector 1 is fixed to the side of the pipe pile 4 by screws. The connector 1 is tied to the outside of the pipe pile 4 by clamp 2. When the flange 5 is connected to the end plate 3 by screws, the horizontal part of the connector 1 is sandwiched between the flange 5 and the end plate 3.

[0024] During the tensile test, the tensile force is transmitted by the connection between the end plate 3 and the pipe pile 4. At the same time, the upward tensile force of the end plate 3 also acts on the horizontal part of the connector 1, so that the vertical part of the connector 1 applies auxiliary tensile force to the pipe pile 4 by means of screws, thereby improving the tensile strength between the end plate 3 and the pipe pile 4.

[0025] like Figure 2 As shown, multiple clamps 2 are provided. The clamps 2 serve to clamp the connector 1 and the pipe pile 4, further increasing the effect of the vertical part of the connector 1 on the tensile force transmission to the pipe pile 4. In addition, the screw connecting the vertical part of the connector 1 to the pipe pile 4 is located below at least one of the clamps 2, so that the clamp 2 and the end of the screw can abut against each other, increasing the binding strength of the clamp 2 on the connector 1.

[0026] like Figure 4 As shown, the contact side between the vertical part of the connector 1 and the pipe pile 4 is a non-smooth surface. For example, a toothed surface is provided on the inner side of the vertical part of the connector 1 to increase the contact friction between the vertical part of the connector 1 and the pipe pile 4, and further improve the effect of the vertical part of the connector 1 on the transmission of tensile force to the pipe pile 4.

[0027] like Figure 2As shown, the top of the screw hole 31 on the surface of the end plate 3 has a diameter expansion groove extending to one side with gradually expanding diameter, when connecting the flange 5 with the end plate 3 by screws, each screw is inserted into the side with larger size of the diameter expansion groove first, then the flange 5 is rotated to move all the screws to the side with smaller size of the diameter expansion groove synchronously, ensuring that all the screws are accurately aligned with the screw hole 31.

[0028] Embodiment two: as Figure 3 As shown, the top horizontal part of the connecting piece 1 is provided with a through hole 11, the through hole 11 is aligned with the screw hole 31 on the surface of the end plate 3, when connecting the flange 5 with the end plate 3, the screw is connected with the screw hole 31 after penetrating through the through hole 11, increasing the connecting strength between the horizontal part of the connecting piece 1 and the end plate 3.

[0029] Although the embodiments of the present application have been shown and described, it should be understood by those ordinary skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the present application, the scope of the present application is defined by the appended claims and their equivalents.
