Description

TECHNICAL FIELD [0001] The present invention relates to a vertical straightening member for vertical and horizontal alignment,

The present invention relates to a straightening member capable of ensuring horizontal and vertical structural integrity and a construction method thereof. More specifically, the present invention relates to a water jetting apparatus and a method of constructing the water jetting apparatus, which are capable of securing a horizontal and vertical structural integrity for effectively constructing a vertical hollow from the ground to the ground in the construction of an underground tunnel or the like.

If you look at the conventional construction method, first, the ground is excavated to a certain depth. In addition, the retaining walls are installed inside the excavated soil to prevent the soil from loosening or collapsing, and support it by using struts. Repeat this process until the planned depth is drilled step by step, then install the mold from the floor and pour the concrete to construct the straight wall.

However, such on-site pouring method has disadvantages that work procedure is complicated and labor intensity is high, resulting in avoidance of work and increase of labor cost. In addition, not only long-term tunnel construction period is required because concrete is cured in the field, It is difficult to expect a uniform construction quality.

1A, a step of installing a pile 20 at regular intervals so as to form a circle on the ground, a step of excavating the imaginary circular inner ground formed by the piles to a depth equal to the height of a concrete block made to a predetermined size , Attaching the concrete block (10) to the pile (20) along the inner circumferential surface of the excavated ground, integrating the concrete blocks to integrate the concrete block, and inserting the concrete block And performing a backfill injection (40) between the precast concrete segment block and the backfill concrete block. At this time, it can be seen that the bottom plate 30 is formed on the bottom of the water hole.

Figure 1B is a perspective view of the pre-fabricated precast concrete segment block (10, concrete block).

The concrete block 10 is made of reinforcing bars and concrete, and has a predetermined area and thickness, and is formed as a plate having a curved shape with a predetermined curvature as a whole. An injection hole 11 for injecting the backfill 40 is formed at the center of the injection hole 40 in the middle of the construction of the vertical hole, and fastening portions 12 for connecting the other concrete blocks are provided at the upper and lower ends and the left and right ends.

The fastening part 12 has a concave part 13 formed at an edge of the concrete block 10 and a fastening plate 14 having a bolt hole 15 formed in its end face is integrated with the concrete block 10 So that bolts or the like are fastened to the fastening plates of other concrete blocks through the recessed portions 13 and then fixed. The concrete blocks 10 are cylindrically-shaped when a plurality of concrete blocks 10 are continuously connected to each other.

Therefore, it is possible to shorten the construction period by simple construction by assembling the concrete block manufactured in the factory and constructing a straight hole, and it is possible to have an advantage that it is easy to standardize and maintain a uniform construction quality.

However, as the diameter and depth of the vertical sphere increase, the number of connection parts connecting the plurality of concrete blocks 10 with the bolts and the like in the up and down and left and right sides must be increased and the connection performance may be deteriorated. There is no other way.

Therefore, there is a method of reducing the connection area by enlarging the size of the concrete block. However, since the weight of the concrete block is increased, the workability may be lowered. There is a problem that it is not enough to secure the integrity.

Accordingly, the present invention can provide a concrete structure capable of securing the concrete part of a concrete block by securing a connection part performance by constructing a water hole by allowing a concrete block to be manufactured in a size capable of carrying and lifting the concrete block. And to provide a method for constructing a vertical straightbody that is capable of ensuring horizontal and vertical structural integrity capable of ensuring horizontal and vertical structural integrity.

According to an aspect of the present invention,

In order to connect the concrete blocks to each other, it is not necessary to use a fastener such as a conventional bolt, but to connect the concrete blocks to each other, The horizontal connection bars are connected to each other to constrain the concrete blocks to each other.

When the concrete blocks are stacked so that the connection ends that are blocked out are vertically communicated with each other, the vertical connection reinforcing bars are disposed at the connection ends that are connected to each other.

The block out portion is closed with a filler such as concrete so that the vertical connection reinforcing bars and the horizontal connecting reinforcing bars are embedded.

Accordingly, in the present invention, the concrete block is restrained to each other by using the horizontal connection reinforcing bars, and the vertical connection reinforcing bars are arranged in the block-out portions vertically communicating with each other. Thus, the horizontal connecting reinforcing bars and the vertical connecting reinforcing bars are closed with concrete, To ensure sufficient structural integrity.

To this end,

First, a connection flange is formed which is extended to both end outer sides so as to be formed into a blocked out connection end S; A horizontal connecting reinforcing bar extending from the inside to the connecting end portion S; And a connection block connecting the horizontal connection reinforcing bars to each other so that the concrete blocks are vertically stacked so that the connection ends are communicated with each other,

And a vertical connection reinforcing bar which is vertically connected to the block-connected connection end S and is joined to the horizontal connection reinforcing bar so as to be vertically connected to the block- Provide a straight-through ball that can secure structural integrity.

In addition, (a) the block-out connected ends S of the pre-fabricated concrete blocks are set in contact with the end faces of the connection flanges of the concrete blocks according to the cross-sectional shape of the vertical holes to be constructed, Connecting the horizontal connecting reinforcing bars drawn out from the horizontal connecting reinforcing bars to each other by using connectors, horizontally restraining the set concrete blocks; (b) disposing a vertically connected reinforced concrete block stacked vertically on the inner side of the block-out connected end portion (S) communicated vertically by the upper and lower lamination of the horizontally confined concrete block; And (c) finishing a filling end material by filling the connection end portion (S) blocked out so that the vertical connecting reinforcing bars and the horizontal connecting reinforcing bars are embedded, thereby completing the upper and lower stacked concrete blocks The present invention provides a method for constructing a vertical straight line which can secure horizontal and vertical structural integrity.

According to the present invention, even if the size of the concrete block for the straight pipe construction is maximized, it is very advantageous for the construction of the large straight pipe according to the securing of the structural integrity because the connection part performance by the connecting reinforcing bar and the filler is sufficient.

In addition, since the connecting portion is closed by concrete such as non-shrinkage concrete instead of being fastened by simple bolt fastening or the like, the concrete structural integrity of the concrete block can be ensured.

[The present invention is a sole formed so as to ensure the horizontal and vertical structural integrity]

FIG. 2A is a perspective view of a concrete block of a vertical sphere capable of ensuring horizontal and vertical structural integrity of the present invention, and FIGS. 2B and 2C are vertical sectional views of a vertical sphere capable of ensuring horizontal and vertical structural integrity by the concrete block 100 used in the present invention Fig.

As shown in FIG. 2A, the concrete block 100 is determined according to the cross-sectional shape of the vertical hole 300, but since the vertical hole is generally constructed as a vertical tunnel having a circular cross-section, .

In other words, in order to construct a vertical hole, the ground is excavated in advance, and a concrete block (100) may be laminated in the form of a circular ring inside a hypothetical building (a file such as H steel frame) installed on the excavation surface. The concrete block 100 made of semicircular material is used.

It can be seen that both end portions of the concrete block 100 are formed with the block-out connection end portion S to form the connection flange 110.

That is, in the concrete block 100, the extended flange 110 extending from the outer side is formed so as to protrude so that the blocked out connection end S in which the horizontal connecting reinforcing bars and the vertical connecting reinforcing bars are received is formed at both ends.

Further, it can be seen that a horizontal connection reinforcing bar 120 is formed at the connection end S to be drawn out from the convex inside of the concrete.

When the horizontal connection reinforcing bars 120 are connected to each other by a coupling 130 such as a coupler, the horizontally adjacent concrete blocks 100 are horizontally constrained to each other to facilitate self-standing installation.

Next, as shown in FIG. 2B and FIG. 2C, when the horizontally confined concrete block 100 is stacked vertically, it can be seen that the blocked out connection ends S can be communicated up and down.

The vertically connecting reinforcing bar 140 is vertically and continuously disposed at the connection end S connected to the upper and lower sides. The vertical connecting reinforcing bar 140 binds to the horizontal connecting reinforcing bar 120 at this time.

In other words, the vertical connection reinforcing bar 140 is disposed over the entirety of the block-out connection end S, which is vertically communicated with the bottom concrete block and the top concrete block, so that the horizontal and vertical structural integrity of the concrete block can be secured .

A mold 150 (using a steel formwork in the form of a sheet material conforming to the shape of the block-out connection end) capable of covering the connected end S of the block-out connected upper and lower ends is provided, When the filler 160 such as non-shrinkage concrete is filled and cured in the mold 150 so that the reinforcing bars 120 are embedded, the upper and lower stacked concrete blocks 100 can be integrated horizontally and vertically.

Since a large number of concrete blocks 100 are installed in the block end S, the filling finishing material 160 can be used for rapid construction. Therefore, the workability is greatly improved, And the vertical connection reinforcing bars 120 and 140 are finished with the filling finishing material 160 at the connection end portion S where they are blocked out so that the concrete block 100 can be structurally integrated in the vertical and horizontal directions.

Therefore, compared to the case where a conventional concrete block is fastened with a bolt or the like, there is a difference in the number of the connection part formation, and when a load is applied to the connection part, resistance to bending moment becomes large, .

Further, the concrete blocks 100 stacked in the vertical direction are stacked by using the front grooves formed on the upper surface and the shear keys to restrain sliding of the joint surfaces, and can be located in separate vertical holes formed in the concrete block 100 The prestress is introduced into the vertical steel bar vertically connected by the coupler, so that it can be prevented from penetrating in the vertical direction and penetrating groundwater or the like from the surrounding ground. The vertical steel bars, shear grooves, and shear keys are referred to as vertical joints 400 in the present invention.

[Method for constructing a self-centering tool made to be able to secure the horizontal and vertical structural integrity of the present invention]

FIGS. 3A, 3B and 3C illustrate a flow diagram of a method for constructing a golf ball in which the horizontal and vertical structural integrity can be ensured according to the present invention.

First, as shown in FIG. 3A, a hypothetical example 200 is constructed on the ground for the construction of a vertical hole.

In order to prevent the ground collapse due to the vertical excavation of the ground, the soil wall may be constructed by using the conventional thumb pile 210 and the earth plate. When the excavation depth is large or in the case of soft ground, the SCR method The construction of the underground continuous wall 220 by the construction method may be performed.

3A, the case where the thumb pile 210 is installed and the underground continuous wall 220 is installed on the back surface of the thumb pile 210 and the inner ground is downwardly installed while the wale 230 is installed on the thumb pile, .

Therefore, when the installation 200 is completed, a work space is formed by excavation of an inner ground, and a concrete structure such as a straightener 300 is installed in the work space.

Such a concrete structure is constructed using the concrete block 100 of the present invention. First, a semicircular concrete block 100 is manufactured in advance at a factory and brought into the site (using a crane (not shown), etc.). The height and thickness of the concrete block 100 are determined depending on the diameter of the vertical sphere 3a, it can be seen that a semicircular concrete block 100 is provided.

The concrete block 100 may be a precast concrete block manufactured in advance.

Next, as shown in FIG. 3B, in a state where the end faces of the connection flange 110 are in contact with each other at the block end S of the concrete block 100 on the upper surface of the bottom plate of the bottom of the excavated soil, The reinforcing bars 120 are connected to each other by using a coupling 130 such as a coupler.

It can be seen that the two lowest concrete blocks 100 can be restrained horizontally with respect to each other.

When the new concrete block 100 is stacked on the upper surfaces of the two concrete blocks 100 horizontally constrained to each other, the horizontal connection reinforcing bars 120 are connected to each other at the connection end S, It can be seen that they are formed in an assembled state.

As shown in FIG. 3C, a vertical connection reinforcing bar 140 is disposed on the block-out connection end S which is communicated with the upper end of the connecting end portion S, and a filling finishing material 160, such as non-shrinkage concrete, S in the form of a mold.

At this time, the vertical connection reinforcing bars 140 are disposed over the entirety of the block-out connecting ends S, which are vertically communicated with the concrete block at the lowermost stage and the concrete block at the uppermost stage.

When the filling finishing material 160 is laid in the mold 150 to cure the concrete blocks 100, the integrated concrete blocks 100 can be secured to the left and right and up and down.

Of course, the predetermined height may be determined in consideration of the possibility of the vertical connection reinforcing bars being laid, etc., and the concrete reinforcing bars 140 are laid after all the concrete blocks 100 are laid, and then the filling finishing material 160 is laid.

As a result, it can be seen that the final circular structure 300, which is a final circular structure, is formed inside the hypothetical structure. If only the straight holes 300 are to be formed, a vertical hole may be formed to contact the hypothetical structure.

Further, by using the vertical joint 400 as described above, the concrete block 100 is made to have a prestressed upper and lower portions.
