The present invention relates to a method for installing a pile using soil and a grouting material. More specifically, the method for installing a pile using soil and grouting embeds a pile in the ground, and comprises: (a) a step of surveying a location where a pile is to be inserted by a design; (b) a step of making grouting liquid in a gel form mixed with soil dug when excavating and then injecting the grouting liquid into equipment capable of excavating and spraying the grouting liquid; (c) a step of excavating a point surveyed in step (a) and spraying the grouting liquid to mix the grouting liquid and soil dug when excavating to make a gel form; (d) a step of embedding and seating a pile selected by structural calculation in the mixture of the gel form; and (e) a step of curing the mixture after step (d). The present invention almost completely eliminates slime produced when excavating to eliminate a need for a slime removal process and mixes the grouting liquid and soil to reduce a grouting material when excavating to shorten construction time and reduce construction costs. Also, a steel pipe or a PHC pile is inserted into a material in a gel form in which the soil and the grouting liquid are mixed to form a foundation to be used as a foundation of a skyscraper or an important structure. Also, the present invention excavates the ground and sprays the grouting liquid at the same time to form a gel form on a location where the pile is to be installed to easily insert the pile by the weight of the pile to drastically reduce a pile installation step to shorten construction time and reduce construction costs.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a pile using soil and grouting,

The present invention relates to a method of constructing a file that forms the basis of a structure.

In general, when a high-rise building or a reinforced concrete structure is to be built, a basic construction is carried out by putting a PHC file or an H-type beam on the ground in order to strengthen the foundations, and the construction of the above- It is a very important construction for building structures.

As a method of constructing the above-mentioned file, a piling method and an excavation method have been introduced. The method of installing the electron is as follows: a method in which the hammer of the weight is elevated by using a hoisting rope installed on the upper part of a leader installed vertically in the crawler traveling device, So that the pile is poured into the ground while the hammer is raised and lowered. In the latter excavation method, a screw file mounted on a file connection part is rotated to excavate the ground to form a pile hole, and then the screw file is reversed to be pulled out from the excavated pile and inserted into the pile .

However, in the existing method using the screw file, there is an inconvenience that the slime occurring in the ground drilling is excessively generated, and the slime rising from the drilling hole must be removed by the excavator every time the drilling is performed. In addition, since the drilling apparatus and the injection apparatus for injecting are separately developed, there is a problem that the process for installing the pile is very troublesome, and the grouting material is excessively entered by removing all the soil from the perforation hole and performing the grouting, resulting in an economical problem.

In order to solve this problem, Patent No. 10-1441929 has been proposed. However, since the patent is merely punched and mixed with green slime and grouting material to form a file, stable design supportability can not be sufficiently exhibited. There is a problem that can not be used as a basis. In addition, in order to secure the design supporting force by using the above-mentioned patent, the number of files is excessively increased, which also causes economical problems.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a method of constructing a file using soil and grouting according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart of a file construction method of the present invention.

The present invention relates to a file installation method using soil and grouting material, and more particularly, to a construction method for installing a file on a ground, comprising the steps of: (a) (C) injecting the grouting solution into an apparatus capable of injecting excavation and grouting solution after preparing a grouting solution which is mixed with the soil generated during excavation to form a gel state; and (c) A step of injecting a grouting solution while excavating the mixture to form a gel state by mixing the soil and the grouting liquid generated during excavation, and (d) And (e) curing after the step (d).

The present invention comprises steps (a) to (e), wherein a slime removal process is not necessary at the time of construction of a file, and a place where the excavation is performed is in a gel state so that it can be inserted by the weight of the file, The present invention relates to a file construction method using soil and grouting material that can save a construction period and a construction cost of a file.

However, in the existing method using the screw file, there is an inconvenience that the slime occurring in the ground drilling is excessively generated, and the slime rising from the drilling hole must be removed by the excavator every time the drilling is performed. In addition, since the drilling apparatus and the injection apparatus for injecting are separately developed, there is a problem that the process for installing the pile is very troublesome, and the grouting material is excessively entered by removing the soil from the perforation holes and performing the grouting.

That is, the present invention does not require a slime removing process because there is almost no slime generated at the time of excavation, and the grouting solution is mixed with the gravel to reduce the material for grouting at the time of excavation so that the construction period and the construction cost of the pile can be saved . In addition, the present invention can be used as a foundation of a high-rise building or an important structure by forming a foundation by inserting a steel pipe or a PHC file into a gel-like material mixed with a soil and a grouting solution. In addition, the present invention is an invention in which the grouting solution is simultaneously injected while excavating the ground, the position where the file is to be constructed is in a gel state, and can be easily inserted by the weight of the file, thereby dramatically reducing the construction step of the file. It is an invention that can save construction cost.

Step (a) is a step of measuring a position where a file is to be constructed by design. That is, step (a) is a step of accurately measuring the location where the file is to be installed, so that the file can be accurately installed on the ground to be grounded to construct the file.

(b) is a step of injecting the grouting solution to be drilled into the hole to be drilled into the equipment capable of spraying the grouting solution. That is, step (b) is a step of mixing the grouting solution mixed with the slurry generated in the excavation to form a gel state, and injecting the grouting solution into the apparatus capable of spraying the perforation and grouting solution. The grouting solution is a material prepared by mixing the grouting material to be charged with water at a predetermined ratio. The equipment that can inject excavation and grouting liquid is the equipment commonly used in the construction site.

(c) is a step of spraying the grouting solution while excavating the ground to construct the pile according to the design. That is, in the step (c), the grouting solution is injected while excavating the point measured in the step (a), so that the soil and the grouting solution generated at the excavation are mixed to make a gel state. In addition, step (c) is a step of spraying the grouting solution by repeatedly excavating and rotating the excavation equipment to make the measured gel state in design. In the step (c), the gel state in which the soil and the grouting liquid are mixed is a state where the pile is easily inserted and seated when the pile is inserted.

(d) is a step in which a file selected by the structural calculation according to the site is inserted and settled. That is, step (d) is a step in which a file selected by the structural calculation is inserted into the gel-like mixed material constructed in step (c). For example, a gel state is a state in which a file can be easily inserted by the weight of the file when it is inserted. (d) is a step in which a file is inserted into a gel-like mixed material so as to be utilized as a basis of a high-rise structure or an important structure, in order to secure a stable endurance. That is, the pile is mixed with the mixed material in the gel state so that the pile is incorporated into the mixed material in the gel state to effectively support the load from the top. The file is a file selected by structural calculation according to the purpose of the foundation and the site, and a steel pipe, a PHC, or the like can be used.

In addition, the step (d) may further include the step of placing a file in the gel mixed material by applying a load to one end of the file. That is, in order to accelerate the penetration of the pile according to the air in which the foundation is constructed, a load may be applied to one end of the pile to allow the pile to be introduced into the gel-state mixed material sooner. Here, a method of applying a load to one end of a file may be performed by rotating the file while rotating the file, by vibrating the file using a vibration device, or by striking one end of the file, It is possible to apply a load by applying a load.

(e) is a step of curing after the step (d). That is, after the pile is inserted into the mixed material in the gel state, the pile is cured for a certain time so that the pile and the mixed material are integrated.
