Abstract

The invention relates to a construction method for integrally pouring a prestressed pipe pile with a conjoined pile cap. The construction method comprises the following construction steps of (1) preparing for construction; (2) driving a pipe pile; (3) annularly cutting off the pile top; (4) arranging a pile cap reinforcement cage; (5) erecting a pile cap formwork; and (6) pouringpile cap concrete. The construction method has the beneficial effects that the driving direction of the pipe pile is controlled through a guide sleeve, and the stability of the guide sleeve can be increased by virtue of a pipe side ballasting body and a support plate anchor bar; and an inner supporting and pressing plate and an inner vertical rod are inserted into a pipe cavity of the pipe pile, vertical support is provided for the inner vertical rod through an inner support rod and the inner supporting and pressing plate, the pile cutting height can be controlled through a vertical position rod, slurry in the cutting process is synchronously recycled through a slurry recycling tank, the pile cutting and positioning difficulty is lowered, and the site construction environment is protected.

Description

technical field [0001] The invention relates to a construction method for integrally pouring prestressed pipe piles with integrated pile caps, which can effectively reduce the difficulty of pile cutting and pile cap construction, improve on-site construction efficiency, and protect the on-site construction environment, and is suitable for foundation treatment of prestressed pipe piles project. Background technique [0002] With the rapid development of the economy, there are more and more basic engineering construction contents. In the process of infrastructure construction, the construction technology of prestressed pipe piles is widely used and continues to develop and mature. However, during the construction process of the pile body and pile cap, the pouring construction is often divided into two times, which has problems such as long construction time and difficult positioning of pile cutting. [0003] In the prior art, there is a prefabricated hollow pile cap for compo...
