Connection structure of prestressed concrete pipe piles

Abstract

The invention discloses a connection structure of prestressed concrete pipe piles. The connection structure of the prestressed concrete pipe piles comprises two concrete pipe pile bodies. Steel platesare fixedly installed at the ends, close to each other, of the two concrete pipe pile bodies correspondingly, first through holes are correspondingly formed in the tops of the steel plates, and the sides, close to each other, of the two steel plates are in contact with each other. A plurality of first clamping grooves are formed in the tops of the steel plates located on the lower portion, and the first clamping grooves are in a ring shape. First clamping columns which are fixedly installed on the bottoms of the steel plates located on the upper portion are movably installed in the first clamping grooves in a clamping mode, second clamping grooves are formed in the sides, away from the corresponding first through holes, of the first clamping columns, third clamping grooves are formed in the inner walls of the bottoms of the second clamping grooves, and first rectangular holes are formed in the inner walls of the sides, away from the corresponding first through holes, of the first clamping grooves. According to the connection structure of the prestressed concrete pipe piles, the structure is simple, the concrete pipe pile bodies can be connected and fixed quickly, the installationtime is saved, and the work efficiency is improved; and restriction to second clamping columns is fast removed advantageously, and use of later pile distribution again is facilitated.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a connection structure of prestressed concrete pipe piles. Background technique [0002] With the development of national economic construction, more and more high-rise buildings, airports, docks, and municipal projects are being constructed, among which prestressed concrete pipe piles are widely used as vertical pressure piles, and because of the The elevation of the original landform is different, and it is difficult to have pipe piles with specifications that just meet the elevation of the landform, so pipe piles are often used with piles. [0003] Most of the existing technologies use welding technology to connect every two pipe piles, but welding piles have many shortcomings. The process of welding piles is demanding, time-consuming and labor-intensive, making it inconvenient to quickly connect pipe piles Fixed, resulting in low work efficiency, so we propo...

[0003] Most of the existing technologies use welding technology to connect every two pipe piles, but welding piles have many shortcomings. The process of welding piles is demanding, time-consuming and labor-intensive, making it inconvenient to quickly connect pipe piles fixed, resulting in low work efficiency, for which we propose a connection structure for prestressed concrete pipe piles
