Description

Technical Field

[0001] The utility model relates to the technical field of concrete pipe piles, in particular to an improved concrete pipe pile. Background Art

[0002] Railway soft foundation is the treatment of the railway roadbed to improve the bearing capacity and stability of the roadbed. To improve the bearing capacity of the roadbed, concrete pipe piles need to be installed inside the roadbed. When concrete pipe piles are installed inside the roadbed, hammering or static pressure is generally used. When the first pipe pile does not reach the set length, the second pipe pile needs to be installed on the first pipe pile, and the second pipe pile is then installed inside the roadbed.

[0003] There is an existing concrete pipe pile (application number: 202322703753.6) which improves the stability of the pile-column connection through a pile-column connecting mechanism, and realizes knocking the protection block to prevent the pile-column surface from being damaged through a pile-column protection mechanism. The above-mentioned problem still exists. When the concrete pipe pile is used, due to the different depths of the pile holes, multiple concrete pipe piles need to be combined. When two concrete pipe piles are connected, the above-mentioned device connects by inserting the connecting plug into the groove. Since multiple connecting plugs are provided, it is necessary to align the connecting plug with the corresponding groove for installation. The weight of the concrete pipe pile is large, and it is difficult to make fine adjustments. It is not convenient for the staff to quickly connect the two concrete pipe piles and it is not convenient for the staff to operate. When connecting the two concrete pipe piles, it is necessary to seal the two concrete pipe piles, which is not convenient for the staff to perform multiple sealing work on the concrete pipe pile connection position, and the sealing effect is poor.
