Embodiment

[0026] to combine figure 1 , figure 2 , the present invention provides a construction method for earthquake-resistant and pull-out pipe piles, which is used for the construction of prefabricated pipe strings 4 . This method mainly comprises the following steps:

[0027] Step 1: At the set pile position, dig a square installation hole according to the diameter of the pipe pile. In order to ensure the strength of the construction, the side length of the installation pit is preferably 2.8-4.5 times the outer diameter of the pipe string 4 .

[0028] Step 2, installing the folded anti-lift piece 3, which is in a folded shape with an inner fold angle of 120-150°. One end of the folded anti-lift piece 3 is a picket 6, and the other end is a mounting column 5. Keep the installation column 5 vertically, and insert the picket 6 into the pit wall of the installation pit. The number of folded anti-pull pieces 3 can be 3-12. In order to facilitate construction, the tail of the picke...

Abstract

The invention discloses a construction method for an anti-seismic and pulling-resisting pipe pile. The construction method includes the following steps that firstly, an installation pit is formed in a set pile position; secondly, a folded pulling-resisting part is installed; thirdly, an anchoring seat and the pipe pile are installed in the installation pit; and fourthly, concrete is poured in the installation pit, and filing and curing are conducted. The construction method is short in construction period, the anti-seismic and pulling-resisting strength of the pipe pile is good, and the bearing force is high.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method for earthquake-resistant and pull-out resistant pipe piles. Background technique [0002] As a new type of pile, pipe pile has been widely used due to its advantages of convenient construction, high bearing capacity, reliable quality and relatively economical. As a foundation treatment and pile foundation form, pipe piles have been greatly developed since the beginning of last century. They are widely used in various building foundations and play a huge role. However, as the pipe column is a prefabricated pile, the construction process has the problems of long construction period and weak earthquake resistance and pullout resistance. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a construction method for earthquake-resistant and pullout-resistant pipe piles. Aiming at the de...
