Tubular pile with good sealing effect and core filling method

Abstract

The invention provides a tubular pile with a good sealing effect and a core filling method. The tubular pile comprises a tubular pile body, wherein a core filling part area is arranged at the top of an inner cavity of the tubular pile body, a sand filling and grouting part area is arranged at the bottom of the inner cavity of the tubular pile body, the top end of the tubular pile body is in bolt connection with a pile top end blocking plate, the bottom end of the tubular pile body is in bolt connection with a pile bottom end blocking plate, and threaded grooves are formed in the peripheries ofthe pile top end blocking plate, the pile bottom end blocking plate and the inner cavity of the tubular pile body. According to the tubular pile with the good sealing effect and the core filling method, through the cooperation of a sealing gasket, sealing treatment can be carried out between the tubular pile body and the pile top end blocking plate and between the tubular pile body and the pile bottom end blocking plate; through the cooperation of a limiting groove, a fastening disc, a water-swelling pad and a fastening bolt, overall fixed sealing can be carried out between the tubular pile body, the sealing gasket, the pile top end blocking plate and the pile bottom end blocking plate; and through the cooperation of a stainless steel hoop, auxiliary reinforced sealing treatment can be carried out on the outer side of the joint position of the sealing gasket, the pile top end blocking plate and the pile bottom end blocking plate, so that the overall sealing performance of the joint position of the tubular pile is directly enhanced.

Description

technical field [0001] The invention relates to the field of pipe pile core filling construction, in particular to a pipe pile with good sealing effect and a core filling method. Background technique [0002] Pipe piles are divided into post-tensioned prestressed pipe piles and pretensioned prestressed pipe piles, prestressed concrete pipe piles (PC pipe piles), prestressed concrete thin-walled pipe piles (PTC pipe piles) and high-strength prestressed concrete pipe piles. Pile (PHC pipe pile). [0003] When the construction unit is carrying out construction work, it is necessary to dig a foundation pit to pre-embed pipe piles. As the depth of pipe piles continues to deepen, it is necessary to connect multi-section pipe piles to pre-embed core filling operations. However, the existing pipe piles are filling During the core pre-embedding process, the sealing effect of the joints of the pipe piles is poor, and during the pre-embedded drilling of the pipe piles, they are squeez...
