Problems solved by technology

[0002] In the past, as foundation piles, there were concrete pouring piles. The piles were mainly used to bear the upper load, that is, to bear the pressure. They were not suitable for bearing the tension. To provide an anti-pullout device, the assembly and construction of this kind of device with anti-pullout force is very troublesome

Embodiment Construction

[0019] The construction method of cast-in-situ concrete anchor pile of the present invention is carried out like this, at first, as Figure 1a As shown, drive the outer casing 1 into the foundation until the specified depth, and then Figure 1b As shown, with the outer casing 1 as a guide, the heavy hammer 2 repeatedly rams the foundation soil at the bottom of the outer casing 1 up and down until the above-mentioned heavy hammer 2 extends downward for a specified distance from the bottom of the outer casing 1 and forms a pile end holes, then as in Figure 1c As shown, the above-mentioned weight 2 is lifted upwards from the top of the above-mentioned outer casing 1, and then a reinforcement cage 3 is inserted into the above-mentioned casing 1. The bottom of the reinforcement cage 3 is formed with an expandable diameter portion 6, and the diameter-expandable portion 6 It is mainly formed by longitudinal steel bars, and the part (upper part) in the steel cage 3 other than the ab...

Abstract

A construction method for in-situ pouring concrete anchor pile includes tamping external sleeve pipe into foundation, tamping the fundation by weight hammer reciprocating along the sleeve pipe to form a hole under pipe bottom, taking the weight hammer out, inserting the reinforcing bar cage with an expandable part into sleeve pipe, inserting internal sleeve pipe into the reinforcing bar cage, repeatedly filling and tamping in internal sleeve pipe until the expandable part is expanded to form a horn shape,and lifting up the internal and external sleeve pipes while filling concrete in it to form a rigid concrete pile.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to the field of ground foundations. Background technique [0002] In the past, as foundation piles, there were concrete pouring piles. The piles were mainly used to bear the upper load, that is, to bear the pressure. They were not suitable for bearing the tension. An anti-pullout device is provided, and the assembly and construction of such a device with anti-pullout force are very troublesome. Contents of the invention [0003] The present invention is proposed in order to solve the above-mentioned problems, and the purpose is to provide a construction method of cast-in-place concrete anchor piles, by which the above-mentioned anchor piles can be formed quickly and easily, and it has high compressive bearing capacity and Pullout resistance. [0004] Above-mentioned purpose of the present invention is realized by the construction method of following cast-in-place concrete anchor...
