Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, and more specifically to a pipe pile end plugging device. Background Art
[0002] Pipe piles refer to continuous or separate pipes or steel pipe piles buried underground. They bear the weight and load of structures such as buildings or bridges through the support and friction of the soil. It is a common foundation reinforcement technology. The Fengtai Bridge Factory of the Ministry of Railways began to produce pre-tensioned prestressed concrete pipe piles (PC pipe piles for short), which were mainly used for the foundation construction of railway bridge projects at that time; in the 1970s, post-tensioned prestressed concrete pipe piles were developed and produced. Since the 1970s, especially in the construction of Shanghai Baoshan Iron and Steel Plant, a large number of steel pipe piles introduced from Japan have been used, which are not only expensive but also have poor durability.
[0003] For example, a pipe pile end plugging device disclosed in publication number CN118007644A comprises: an elastic member 1, an elastic member 2, a bag, an adjusting tube group, and a connecting ear. The present invention blocks the inner hole of the pipe pile by the bag, and then fixes the bag to the pipe pile by the elastic member 1, that is, fixes the bag to prevent the bag from moving downward to the inner hole under force, thereby preventing soil from falling into the inner hole of the pipe pile. In addition, the present invention adjusts the diameter of the bag by moving the outer tube up and down along the inner tube, so that it can be adjusted according to various specifications of pipe piles to achieve the plugging of the inner holes of different pipe piles, and has strong applicability.
[0004] It can be seen from the above-mentioned public scheme that, at present, when the end of a pipe pile is sealed, the sealing device is directly connected to the end of the pipe pile, and the pipe pile and the sealing device are easy to fall off, thereby affecting the sealing effect. Sand and stones are easy to move to the inside of the pipe pile, affecting the construction work. At the same time, when taking and placing the sealing device, the sealing device is mostly clamped and dragged up by hands. When the hand clamps and drags up the sealing device, the hand and the sealing device are easy to fall off, which easily causes the sealing device to fall and be damaged. Utility Model Content
