Description

{Method of base reinforcement}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ground reinforcement method, and more particularly, to a ground reinforcement method in which a grid-like hole and an upper reinforcing bar and a lower reinforcing bar are connected using a funnel-type assembly.

Due to the recent increase in demand for industrial and residential land due to the recent economic growth, it is necessary to use the land effectively by utilizing the soft ground formed between coast and inland.

In the ground reinforcement method reinforcing the soft ground, a truss type structure is embedded in the ground or a top type pile is placed on the ground so that it can act as a resistance body, so that the load caused by the building or soil can be supported on the ground.

Prior arts for changing such soft ground to stiff ground include Application No. 10-2007-0059006, No. 10-2003-0085185, No. 10-2007-0115228, No. 10-2007-0059006 .

Particularly, in the case of reinforcing the ground using a top-shaped pile, there is a problem that the reinforcing effect is poor and the reinforcing method is required to be carried out in a double manner, and the reinforcing method itself is difficult, .

An object of the present invention is to provide a ground reinforcement method which has an improved ground reinforcement effect than the conventional method, and which is not easily deformed even when the soil load is changed, and is easy to reinforce the ground reinforcement method.

The method of reinforcing a ground according to the present invention comprises the steps of perforating holes in a lattice form, assembling a lower reinforcing bar in a lattice form so as to overlap at the upper side of the hole, An upper reinforcing bar assembling step of assembling an upper reinforcing bar in a lattice shape in an upper depression formed in the assembly, a U-shaped connecting reinforcing bar connecting the upper reinforcing bar and the lower reinforcing bar, And a concrete pouring step for pouring concrete into the inside of the assembly.

The method may further include inserting a cylindrical pipe into the hole formed in the perforating step.

Further, the cylindrical pipe is formed with a depression at an upper portion to which a lower reinforcing bar is coupled.

The ground reinforcement method according to the present invention provides an improved ground reinforcement effect using an upper reinforcing bar, a lower reinforcing bar and a connecting reinforcing bar by using a funnel-type assembly, and provides a ground reinforcement method that is not easily deformed by fluctuation of a soil load do.

In addition, there is an advantage that a cylindrical pipe is combined with a hole according to the kind of the ground, and the upper reinforcing bar and the lower reinforcing bar are coupled to the depression of the assembly.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a flowchart showing a method of reinforcing a ground according to a preferred embodiment of the present invention. FIG.
2 is a perspective view showing an assembly used in a ground reinforcement method according to a preferred embodiment of the present invention;
3 is a flowchart showing a ground reinforcement method according to another preferred embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The ground reinforcement method according to the present invention includes a perforation step, a lower reinforcing steel reinforcing assembly step, an upper reinforcing steel reinforcing assembly step, a connecting reinforcing steel reinforcing steel reinforcing steel reinforcing steel reinforcing steel reinforcing steel reinforcing steel reinforcing steel reinforcing steel pipe reinforcing steel reinforcing steel reinforcing steel reinforcing steel reinforcing steel reinforcing steel reinforcing steel

1 is a flowchart showing a ground reinforcement method according to a preferred embodiment of the present invention.

The perforation step S100 is a step of drilling a hole 10 in a lattice shape on the soft ground 1 and the position of the hole 10 is a part where an upper reinforcing bar and a lower reinforcing bar are combined, The number and spacing should be adjusted considering the softness of the ground. Further, the depth of the hole 10 can be appropriately adjusted in accordance with the degree of softness of the ground to be reinforced.

The next step is the lower reinforcing steel assembling step S200, and the lower reinforcing steel 20 is assembled in a lattice shape so as to overlap at the upper side of the hole 10. [

After the lower reinforcing bar assembling step S200, the lower reinforcing bar 20 is joined to the lower reinforcing bar 20 formed in the funnel-shaped assembly 100, and the assembling step S300 is performed.

2 is a perspective view showing an assembly used in a ground reinforcement method according to a preferred embodiment of the present invention.

As shown in FIG. 2, the assembly 100 has a funnel shape with four upper depressions 110 and four lower depressions 120 formed thereon.

An upper reinforcing bar is coupled to the upper depressed portion 100 in a cross shape, and a lower reinforcing bar is coupled to the lower depressed portion 120 in a cross shape. The inside is made hollow, and the connection reinforcing bar described later is inserted, and the concrete flows into the inside.

Next, the upper reinforcing bar assembly step (S400) is a step of coupling the upper reinforcing bars 30 to the assembly 100 as shown in FIG. 1, and when the upper reinforcing bars are coupled, a basic skeleton is completed.

And then a joining reinforcing bar joining step (S500) for joining the U-shaped connecting reinforcing bars 40 so as to be firmly coupled. The U-shaped connecting reinforcing bar 40 connects the upper reinforcing bar and the lower reinforcing bar so that a more stable structure can be achieved.

When the above process is completed, the reinforcing aggregate 50 is filled between the upper reinforcing bar and the lower reinforcing bar through the concrete pouring step (S600) in which the concrete is poured into the inside of the assembly.

According to another embodiment of the present invention,

3 is a flowchart showing a ground reinforcement method according to another preferred embodiment of the present invention.

The embodiment shown in FIG. 3 further comprises the step of inserting a cylindrical pipe into the hole 10 formed in the perforating step SlOO.

As shown in FIG. 3, the cylindrical pipe 90 is formed with a depression 92 to which a lower reinforcing bar is coupled, and the lower portion 130 of the assembly 100 shown in FIG. And is inserted to be inserted into the cylindrical pipe 90.

The cylindrical pipe 90 plays a role of maintaining a stronger ground when the depth of the soft ground is deep, and the size and depth of the cylindrical pipe should be determined according to the degree of softness of the type of ground to be reinforced.

As described above, the present invention provides a reinforcement method for reinforcing a soft ground, and it is a major technical concept to provide a reinforcement method for reinforcing a soft ground, and since the embodiments described above are only one embodiment with reference to the drawings, .
