AI Technical Summary
During the construction of fan foundation pipe piles, the pile core of prestressed high-strength concrete pipe pile cores are buried due to soil layer collapse during the removal process, resulting in blockage or contamination of the pile holes, and secondary core extraction is required, resulting in inconvenience in construction, material and labor waste. .
Design a high-strength prestressed concrete pipe pile core protection device, adopting a conical plug and limiting plate. The outer wall of the plug is equipped with a rubber layer. The plug and limiting plate are processed from steel plates, and the outer diameter of the limiting plate is larger than that of the tube. The upper port of the plug is large and the lower port is small, ensuring that the plug is closely integrated with the pipe pile and avoiding soil layer collapse and burial.
It effectively avoids blockage and pollution of pile holes, reduces the need for secondary core extraction, reduces the burden on staff, improves construction efficiency, and supports multiple utilization.

Abstract
Description
Technical Field
[0001] The utility model relates to a pile core anti-blocking plate, in particular to a high-strength prestressed concrete pipe pile core protection device, belonging to the technical field of concrete pipe pile construction. Background Art
[0002] When constructing wind turbine foundation pipe piles, the top of the pile is located at -3m of the design elevation. During construction, the pile driver's station elevation is close to the design elevation, and the chassis of the pile driver is a certain distance from the ground. The pile cannot be directly driven into the designed position below the ground. The pile driver is required to cooperate with the pile driver to drive the pipe pile to the design elevation. This process is called pile delivery. When the pile driver is being removed, the surrounding soil collapses and buries the prestressed high-strength concrete pipe pile core, causing the pile hole to be blocked or contaminated. The staff needs to dig out the pipe core for the second time, which brings inconvenience to the subsequent construction and causes waste of materials and labor. Utility Model Content
[0003] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art and provide a high-strength prestressed concrete pipe pile core protection device, wherein a rubber plug is used at the pile core, which is tightly combined with the pipe pile and is not easy to fall off, thereby preventing soil layer collapse from burying the pile mouth and reducing the burden on the staff.
[0004] The technical solution adopted by the utility model to solve the technical problem is:
[0005] A high-strength prestressed concrete pipe pile core protection device comprises a plug, which is distributed in a cone shape, a limit plate is arranged on the top of the plug, and a rubber layer is arranged on the outer wall of the plug.
[0006] The plug and the limit plate are both made of steel plates.
[0007] The plug is tightly inserted into the pile core of the pipe pile.
[0008] The outer diameter of the limiting plate is greater than the outer diameter of the pipe pile.
[0009] The plug is in a conical structure with a large upper port and a small lower port.
[0010] The positive beneficial effects of the utility model are:
[0011] 1. The plug and the limit plate of the utility model are both made of steel plates, the material of which is consistent with the material of the end face of the high-strength concrete pipe pile, and can fully withstand the gravity of the hammering; by arranging a rubber layer on the outer wall of the plug, the plug and the pile core can be inserted tightly together, thereby preventing concrete from entering the pile core, and the staff do not need to perform secondary core digging construction, which reduces the burden on the staff.
[0012] 2. The utility model has a simple structure and is easy to operate. When in use, the device is placed between the pipe pile and the pile driver. The pile driver is hammered by the pile head of the pile driver to make the pipe pile reach the designed position. After the pile driver is taken out, the soil layer can be prevented from collapsing and burying the pile mouth. After the excavation is completed, the device can be taken out and can be recycled for multiple uses, thereby improving the efficiency of concrete pipe pile construction and facilitating the connection between the pile top and the core filling concrete pouring process of the cap.
