Problems solved by technology

[0003] However, in the actual construction process, the efficiency is often very low, and it is difficult to coordinate various parameters of the construction process. The preparation time in the early stage is too long, and the pile connection process takes too much time. During the construction process, problems such as floating piles and tilting will occur, resulting in re-measurement Positioning and replaying greatly reduces efficiency

Abstract

The invention relates to the field of construction of prestress concrete pipe pile construction, in particular to a prestress concrete pipe pile construction method. The method includes the steps of pile position measurement and laying off, pile hammer, pile tip and pile frame selection, pile frame in-place operation, bottom pile in-place operation, hammer piling operation, cycle pile splicing operation, hammer collection and detection. In the pile splicing process, a guide hoop is installed on a pile head on the lower section so as to guide a pile on the upper section to be in place, welding is applied to welding points symmetrically, and the number of welding layers is larger than or equal to 2. The prestress concrete pipe pile construction method aims at overcoming the defects in the prior art, pile splicing time is shortened, efficiency is improved, and the construction period is shortened.

Description

technical field [0001] The invention relates to the construction field of prestressed concrete pipe piles, in particular to a construction method of prestressed concrete pipe piles. Background technique [0002] At present, the development rate of my country's construction industry is very rapid. Among them, prestressed concrete pipe piles (PHC piles) are the most prefabricated pile types used in my country's construction projects in recent years. Compared with the past pile types, it is economical. There are many advantages and characteristics in the level of technology and technology, and the adaptability is very good; [0003] However, in the actual construction process, the efficiency is often very low, and it is difficult to coordinate various parameters of the construction process. The preparation time in the early stage is too long, and the pile connection process takes too much time. During the construction process, problems such as floating piles and tilting will occ...
