Abstract
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a spiral file for a geotechnical construction, and more particularly, to a spiral file for ground construction, and more particularly to a foundation construction of a building or a reinforcement work of soft ground, The present invention relates to a spiral file for ground construction for efficiently performing geotechnical drilling.
According to an aspect of the present invention, A spiral pile for foundation work of a foundation, comprising: a steel pipe (100) into which a grout is injected through a passage provided inside; A screw 200 installed on the outer periphery of the steel pipe 100 and spirally rotating in accordance with the rotation of the steel pipe 100 to penetrate the steel pipe 100 into the ground; And a spade 300 installed in a plate form at the lower end of the steel pipe 100 and being inserted upright at a right angle on the ground to excavate the ground while rotating in the course of penetration of the steel pipe 100.
Description
BACKGROUND OF THE
Generally, the spiral file is used for the purpose of strengthening the ground such as foundation work of the building, reinforcement work of the soft ground, etc. These files are formed by grouting the hole where the file is removed after drilling the ground, And then grouting is performed.
These files raise the weight chain hammer and lower the steel pipe to lower the pile by drilling the ground by installing the pile, or by rotating the steel pipe with the spiral around the piercing screw to drill the ground and install the pile. to be.
Various files are being developed with this background, and their structure can be understood in the prior art documents presented below.
However, in view of the conventional problems,
In the case of a file of a conventional hitting method, since it has a structure to install a file by hitting it by using a hammer or the like, the hitting noise and vibration cause complaints from residents near the construction site,
Particularly, in the case of a conventional screw type file, since the screw pierced with the ground is made of a hollow steel pipe for injecting grout, its tip is not easily punched into a normal pipe shape, There is a problem that the time and workability required to perforate the ground are significantly reduced due to the shape of the spiral, and the grouting is not easy in the state where the soil is blocked by the tip of the steel pipe and the pile is buried.
The present invention has been made to solve the above problems, and it is an object of the present invention to provide a spade for performing ground foundation work using a spiral file provided with a screw on the outer circumference of a steel pipe, The purpose of the present invention is to provide a geared spiral file which can reduce the time required to perforate the ground through the installation, thereby improving the working efficiency.
Further, according to the present invention, a plate for covering soil is installed in a spade provided at a lower part of a steel pipe, thereby preventing the ingress of soil into the steel pipe to prevent the passage of the grout from being blocked.
According to an aspect of the present invention,
A spiral file for foundation work of a foundation, comprising: a steel pipe into which a grout is injected through a flow path provided therein; A screw installed on the outer periphery of the steel pipe and spirally rotating in accordance with rotation of the steel pipe to penetrate the steel pipe into the ground; And
And a spade that is installed at a lower end of the steel pipe in a plate form and is erected at right angles to the ground to excavate the ground while rotating in the process of penetrating the steel pipe,
The steel pipe may further include a first blocking plate which is fixedly coupled to the lower end of the steel pipe to prevent the soil from flowing into the steel pipe and discharges the grout to the outside by using a discharge port penetrating the inside center,
Wherein the spade further comprises a configuration in which a sharp-edged chamfered portion is formed on both sides of a plate of a certain thickness, and the ground is excavated by the chamfered portion,
Wherein the chamfer portion is formed by being bent at an arbitrary angle in the rotating direction of the spade,
Wherein the spade further includes a groove formed with a fastening groove in which a steel pipe is inserted and fixed to an upper portion of the upper portion and a gap is formed in a lower portion of the fastening groove so as to provide a gap space below the steel pipe,
The gap groove is further comprised of a second blocking plate which is fixedly coupled to an inner lower end of the groove to secure the discharge passage of the grout while preventing the soil from flowing into the inside of the steel pipe,
The spade further includes a reinforcing bar that is fixedly coupled to the outer periphery of the steel pipe while supporting a side surface of the spade and supports the excavation load,
Wherein the reinforcing bar is formed in a plate shape and further includes two side surfaces adjacent to each other being in surface contact with the side surface of the spade and the outer circumference of the steel pipe and the contact portion is fixed and fastened,
Wherein the reinforcing bar further comprises a chamfer provided on the spade on an opposite surface at an angle,
Wherein the spade further comprises a secondary spade that is fixedly coupled to the lower end of the spade in an intersecting direction to excavate the ground with the spade,
Wherein the auxiliary spade further comprises a coupling groove and a gap groove having the same outer shape as the spade and formed with an insertion groove into which the lower end of the spade is inserted at a center of the auxiliary spade. File.
According to the present invention, since the space for excavating the ground is installed at the lower part of the steel pipe penetrated into the ground by the screw, the time required for piercing the ground is reduced, and the efficiency of the work is increased.
In addition, since the spade plate is installed on the spade, it is possible to prevent clogging of the discharge passage of the grout by blocking the inflow of soil into the inside of the steel pipe.
