Abstract

A cast-in-situ pedestal pile for building, bridge and foundation is composed of concrete pile column, reinforcing bar cage in the said pile column, grouting pipe bound to the said reinforcing bar cage, and several variable supporting disks. Its forming method includes such steps as drilling hole of pile, squeezing and expanding to form variable supporting disks, putting reinforcing bar in the hole of pile, pouring concrete into pile hole and supporting disks, and cement grounting the pile bottom and supporting disk under sides. Its advantages include high load-bearing capacity and low drained slurry.

Description

1. Technical field:

[0001] The invention relates to a variable bottom-expanding support plate grouting pile and a forming method thereof, which belong to a hole-forming concrete pouring pile and a forming method thereof. 2. Background technology:

[0002] It is well known that ordinary concrete cast-in-situ piles have low bearing capacity, and the strength of the pile body is difficult to exert, and the sediment and virtual soil at the pile tip are not easy to clean, so it has low bearing capacity, high cost, easy to cause large building settlement and large amount of mud discharge, etc. shortcoming. 3. Contents of the invention:

[0003] The purpose of the present invention is to solve the technical difficulties of cast-in-situ piles with low bearing capacity, high cost, large building settlement and large amount of mud discharge, and provide a high bearing capacity, low cost, no sediment virtual soil at the bottom of the pile, and small building settlement. And a variab...
