Anti-sinking building concrete pipe pile and installing method

Abstract

The invention discloses an anti-sinking building concrete pipe pile and an installing method. The anti-sinking building concrete pipe pile comprises a concrete pipe pile body, and the bottom of the concrete pipe pile body is fixedly connected to a pile tip. According to the anti-sinking building concrete pipe pile and the installing method, a damping shock absorber is placed on a pile nail, then a adjusting frame is placed on the surface of an inner wall steel pipe, installation is completed in cooperation with a screw rod, then a pile cap is placed on the top of the concrete pipe pile body, hammering operation can be carried out, the phenomenon that the pipe pile sinks after an existing concrete pipe pile is constructed is avoided, the problems that the pipe pile sinks due to dead weight and is organized to sink without a resistance structure on the surface, construction precision and construction safety are affected, meanwhile, limiting structures during construction are mostly prefabricated, relative adjustment cannot be conducted during site construction, construction efficiency and construction precision are reduced, and the construction progress is affected due to the fact that the prefabricated structure cannot be adjusted due to the complex and changeable construction environment are solved.

Description

technical field [0001] The invention relates to the technical field of concrete pipe piles, in particular to an anti-sinking construction concrete pipe pile and an installation method thereof. Background technique [0002] With the development of reform and opening up and economic construction, prestressed concrete pipe piles began to be widely used in railway systems, and gradually expanded to industrial and civil buildings, municipal, metallurgy, ports, highways and other fields. Due to geological conditions, the Yangtze River Delta and The Pearl River Delta region is more suitable for the application of pipe piles. At present, pipe piles account for about 50% of the output value of the national cement products industry. Pipe piles are divided into post-tensioned prestressed pipe piles, pre-tensioned prestressed pipe piles, and prestressed concrete pipe piles. (PC pipe piles) and prestressed concrete thin-walled pipe piles (PTC pipe piles) and high-strength prestressed con...

Problems solved by technology

[0004] In order to solve the problems raised in the above-mentioned background technology, the purpose of the present invention is to provide an anti-sinking construction concrete pipe pile and its installation method, which has the advantages of an anti-sinking stable limit structure, adjustable structure and stable structure, and solves the problem of existing concrete piles. After the construction of soil pipe piles, there is a phenomenon that the pipe piles sink. The pipe piles sink by their own weight and there is no resistance structure on the surface to organize the sinking, which affects the construction accuracy and construction safety. At the same time, most of the limit structures during construction are The prefabricated ones cannot be adjusted relative to the on-site construction, which reduces the efficiency and accuracy of the construction, and due to the complex and changeable construction environment, the prefabricated completed structures cannot be adjusted, which will affect the construction progress.
