Abstract
Description
Technical Field
[0001] The present application relates to the technical field of pipe pile connection, and specifically to a pipe pile connection structure. Background Art
[0002] Precast piles are made of various materials and in various forms (such as wooden piles, concrete square piles, prestressed concrete pipe piles, steel piles, etc.) in factories or construction sites. The piles are driven, pressed or vibrated into the soil using pile driving equipment. They mainly include two categories: precast concrete piles and steel piles. During the driving process of precast piles, the lower section of the pile needs to be connected to the upper section of the pile.
[0003] At present, the main form of precast pile connection is welding connection. The lower pile section is sunk to a position about 1m from the ground, and the upper pile section is hoisted onto the lower pile section. After adjustment, welding begins. The welding time of each joint is about 40 minutes. The entire pile body stays in the stratum for too long, which can easily cause difficulties in pile sinking and even fail to achieve the expected design goals. After the upper and lower pile sections are welded, the temperature of the joint is high. When sinking the pile, the joint part suddenly encounters groundwater, which quenches the pile head and makes the weld brittle, directly affecting the stress performance of the precast pile. The pile sinking site is generally open-air operation. When welding the joint, it is affected by rain and wind, and the quality of the weld is difficult to guarantee, which poses a hidden danger to the pile connection and directly affects the quality of the pile foundation. In addition, when the wind and rain are strong, construction cannot be carried out, which affects construction efficiency. During welding, a large amount of electricity is consumed and gases that affect air quality and human health are released, and electric sparks are released, which endangers the occupational health of operators and the atmospheric environment. Therefore, it is very necessary to improve the connection form of prefabricated piles to improve the connection efficiency between pipe piles. Therefore, a pipe pile connection structure is proposed to solve the above problems. Utility Model Content
