TH3154A - Methods and tools for making columns in live and compact soil - Google Patents

Abstract

This invention is especially relevant for civil engineering, it involves suitable tools for making poles. Up in the living and compacted soil Which consists of at least 2 parallel shafts and rotate in opposite directions. Screw extruders are parallel with opposite thread ends. Where the opposite end of each screw extruder is connected to a shaft With a drill head that makes loam And the distance between the shaft of the screw extruder must be less than the diameter of the screw, shaft and shaft of the screw extruder. A hole inside the shaft is connected to the feed source and at least one release hole on the shaft of each threaded extruder, which cuts through such internal holes in order to release the auxiliary material and release it. To be mixed with loam. This invention was especially useful for creating compactness around the tracks.

Claims (6)

1. A method for making preliminary columns in there with stabilized and compacted soil. It consists of an initial stage consisting of drilling into the ground with a rotary drilling machine. This will make the soil loam and mix it with the additive material. And during that time, at least partially upward movement of the loam through the auger. And the second phase consists of the removal of the auger from the ground. Which are unique to the drilling machines used are A device consisting of at least two parallel shafts Each shaft drives the drill. Each drill has a drill head. That makes the soil loam at the opposite end of the drive shaft and pitch Between the axis of the drill will be less than the diameter of the drill. The shaft and shaft of the drill consists of A hole connected to the source of the material to be added. And at least one of the release holes that are connected to it, located on the shaft of each drill to release the material to be added. Drills are opposite thread distances and are driven in opposite directions. And which also contains parts for reversing the direction of the drill rotation. The first step is to drive the device into the soil while releasing the additive material through the release hole. In order to mix well with the loamy soil and carry out the second phase. After reversing the rotation direction of the drill By exerting controlled pressure on the device Said while withdrawing it back up. So that the loam mixed with the auxiliary material moves downward through the device This will help the soil compacted. 2. The method as in claim 1, which is unique in that the initial driving and mixing action Will be repeated at least once 3. The device is suitable for the action according to the method of fabrication. It consists of at least two parallel shafts, each of which drives the drill. Each auger has a looser head at the opposite end of the drive shaft. And the distance between the axis of the drill is less than the diameter of the drill shaft and the shaft of the drill consists of a hole connected to the material source to be added. And at least one release hole Which is connected to the hole It is located on the shaft of each drill to release the material to be added. And let it be mixed with loam The drill has opposite thread distances and is driven in rotation. In opposite directions And which also contains parts for reversing the direction of the drill rotation. 4. The equipment as in claim 3, which is unique in that the drill head has a spiral shape. 5. The device, as in claim 3, is unique in that the shaft and drill are kept parallel by means of a pair of supports. 6. The device, as in claim 3, is unique in that the hole of a drill is connected to the input material supply. Different from the source insert material connected to the hole of another drill.
