Description

Retaining Wall Type Soundproof Wall or Soundproof Wall Foundation {Method for constructing soundproof wall or retaining wall}

The present invention relates to a retaining wall type soundproof wall or soundproof wall foundation installation method consisting of reinforcing steel and concrete.

In general, sound barriers are installed around various facilities such as highways, railways, subways, ports, and schools. The soundproof walls are installed at edges along the road to serve as a shielding plate to prevent noise generated from the vehicle from spreading to the area around the road.

In addition, the retaining wall refers to a wall structure that resists soil pressure and prevents the soil from collapsing. The retaining wall is necessary for stacking soil, cutting down mountains, filling shores, and the like.

Conventionally, when constructing such a retaining wall type soundproof wall, it is necessary to go through complicated processes such as casting concrete on the ground, installing rebar on discarded concrete, installing scaffolding (steel pipe) on both sides of the reinforcing bar, installing formwork, concrete placing, scaffolding and dismantling of formwork. .

All of these soundproof wall installations are made by mobilizing human resources, which is a concern for safety accidents, and the construction and dismantling of the formwork takes a lot of time, resulting in a long construction period and a labor cost increase.

In addition, the soundproof wall using formwork has a problem in that the surface of the soundproof wall is rough when additional formwork is formed by successively installing formwork, and additional work such as additional surface grinding is not necessary, and the linearity is not beautiful.

On the other hand, Korean Patent No. 10-1159490 discloses a method for installing the soundproof wall foundation by a mechanized method without installing the formwork using equipment such as a mobile formwork and a slip form paver (slip form paver).

However, this method is limited only to the installation of the L-shaped sound barrier base, there is a problem that still to use the formwork in order to install a sound barrier over a certain height.

Republic of Korea Patent No. 10-1159490

Accordingly, the present invention has been made in view of the above circumstances, and an object thereof is to provide a method for installing a retaining wall type soundproof wall quickly and inexpensively by a mechanized method without using a conventional formwork.

According to an aspect of the present invention for achieving the above object, the installation method of the retaining wall type soundproof wall is the step of pouring concrete on the ground; Installing a first reinforcing bar on the discarded concrete; Fixing the first reinforcing bar by pouring the foundation concrete under the first reinforcing bar; Constructing a first soundproof wall on the foundation concrete to expose an upper end of the first reinforcing bar by using a first movable formwork and concrete placing device; Connecting a lower end of a second rebar to an upper end of the first rebar; Constructing a second stage soundproof wall on the first stage soundproof wall by using a second movable formwork and the concrete pouring device; .

According to another aspect of the present invention for achieving the above object, the installation method of the retaining wall type soundproof wall is a step of pouring concrete on the ground; Installing a first reinforcing bar on the discarded concrete; Fixing the first reinforcing bar by pouring the foundation concrete under the first reinforcing bar; Constructing a first stage soundproof wall to expose an upper end of the first reinforcing bar by using a first movable formwork and concrete placing device; Connecting a lower end of a second rebar to an upper end of the first rebar; Constructing a second soundproof wall on an upper portion of the first soundproof wall to expose an upper end of the second rebar by using a second movable formwork and the concrete pouring device; Connecting a lower end of a third rebar to an upper end of the second rebar; Constructing a third soundproof wall on an upper portion of the second soundproof wall by using a third movable formwork and the concrete pouring device; .

Further, in the step of constructing the first end soundproof wall so that the upper end of the first reinforcing bar is exposed, the first end soundproofing wall is constructed in a state where the upper end of the first reinforcing bar is horizontally bent, and the upper end of the first reinforcing bar In the step of connecting the lower end of the reinforcing bar 2, the upper end of the first reinforcing bar which is bent horizontally is vertically connected to be connected to the lower end of the second reinforcing bar.

In addition, in the step of connecting the lower end of the second reinforcing bar to the upper end of the first reinforcing bar is connected by welding the upper end of the first reinforcing bar and the lower end of the second reinforcing bar.

In addition, in the step of connecting the lower end of the second reinforcing bar to the upper end of the first rebar, a coupler is inserted into the upper end of the first reinforcing bar and the lower end of the second reinforcing bar.

In addition, the first end sound barrier has an "L" shape.

According to the present invention, since the construction of the soundproof wall by stacking the first floor and the second floor using the movable formwork and concrete pouring device, it does not go through the work steps that require a lot of time and manpower such as formwork installation and dismantling. In comparison, the time and cost of constructing a sound barrier can be cut in half.

In addition, in the related art, after disassembling the formwork, the work of repairing the poorly placed surface must be additionally carried out.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, like reference numerals refer to like elements throughout. The same reference numerals in the drawings denote like elements throughout the drawings.

1 is a view showing a sound barrier according to an embodiment of the present invention. 2A to 2F are diagrams sequentially illustrating a method of constructing a retaining wall soundproof wall according to an embodiment of the present invention.

Soundproof walls are generally installed at edges along roads and serve as shielding plates to prevent noise from vehicles from spreading around the road. Retaining wall refers to a wall structure that resists soil pressure and prevents soil from collapsing.
The soundproof wall and the retaining wall have different purposes, but generally have a similar shape, and the soundproof wall in the present invention refers to the retaining wall-shaped soundproof wall, and the soundproof wall foundation is also the same shape, and thus it will not be described separately.

As shown in FIG. 1, the retaining wall type soundproof wall (hereinafter referred to as a soundproof wall) is constructed in the form of an elongated shield plate, and the lower portion thereof extends horizontally to have a stable "L" shape for stable support. The shape of the soundproof wall 10 may be in any form other than the letter “L”, and the present invention is not limited. The soundproof wall 10 is disposed in the form in which reinforcing bars are disposed to reinforce the structure therein, and concrete is poured to surround the reinforcing bars. Here, the soundproof wall is used to include the shape of the retaining wall having a similar shape.

Conventionally, the soundproof wall was constructed by installing formwork to fit the shape of the soundproof wall, pouring concrete into the formwork, and then disassembling the formwork again. However, this conventional method takes a lot of time to install and dismantle the formwork, the overall construction period is long, and there is a problem that the labor cost increases.

The present invention provides a soundproof wall installation method that is quick and low construction cost by a mechanized method using a mobile formwork and concrete pouring device. Concrete placing equipment is a device used in conjunction with a mobile formwork that forms a soundproof wall structure, for example, a device called a slip-form paver. In operation, the movable formwork is moved together with the concrete placing device, where the concrete placing device moves while pouring concrete into the movable formwork.

The height that can be installed at one time by mobile formwork and concrete placing device is limited. Thus, for example, if the height of the soundproof wall is 3m, it is not possible to construct the entire 3m at once by using the movable formwork and concrete pouring device, but the work is performed twice or three times by stacking up the layers. .

When the work is performed twice, for example, the work may be performed in the form of first constructing the first stage soundproof wall at a height of 2m and constructing the second stage soundproof wall at a height of 1m on the first stage soundproof wall. In the case where work is performed three times, for example, the first stage soundproof wall is first constructed at a height of 1.3 m, the second stage soundproof wall is constructed at a height of 0.9 m above the first stage soundproof wall, and the second stage soundproof wall is Work can be done in the form of constructing a third soundproof wall at a height of 0.8m above.

Hereinafter, with reference to Figures 2a to 2f, it will be described in the soundproof wall installation method according to an embodiment of the present invention. In this embodiment, the method of constructing the soundproof wall of 3m height three times is used.

Referring to FIG. 2A, first, the discarded concrete 31 is poured on the ground 1. The discarded concrete 31 becomes a part that provides a basis for raising the structure on the ground 1.

Next, the first reinforcing bar 32 is installed on the discarded concrete 31. The first reinforcing bar 32 is a part included in the interior of the concrete for structural reinforcement is installed to match the shape of the soundproof wall.

Next, referring to FIG. 2B, the foundation concrete 33 is poured into the lower portion of the first reinforcing bar 32 to fix the first reinforcing bar 32. If the first reinforcing bar 32 is not fixed, when the movable formwork moves, the position of the first reinforcing bar 32 is moved to prevent construction of a soundproof wall of a desired shape. For example, the height of the foundation concrete 33 may be 15 cm.

2C is a perspective view illustrating a state in which the foundation concrete 33 is poured on the lower portion of the first reinforcing bar 32. At this time, the upper end portion 32a of the first reinforcing bar 32 is bent horizontally. The reason why the upper end portion 32a of the first reinforcing bar 32 is horizontally bent may be used for connection with a second reinforcing bar located on the upper part of the first reinforcing bar 32 after constructing the first end soundproof wall. will be.

Next, referring to FIG. 2D, the first stage soundproof wall 34 is constructed by using a movable formwork and a concrete pouring device. The height of the first stage sound insulation wall 34 may be about 1.3 m including the portion of the foundation concrete 33.

The shape of the first-stage soundproof wall 34 may have other shapes such as "ㅗ" and "l" in addition to the "L" character, and the shape of the first-stage soundproof wall 34 does not limit the present invention. At this time, the first reinforcing bar 32 slightly protrudes above the first end soundproof wall 34 in a state where the upper end is bent. This is because when the concrete hardens in the state where the upper end of the first reinforcing bar 32 completely enters the interior of the first soundproofing wall 34, it is difficult to connect with the second reinforcing bar located above the first reinforcing bar 32.

Next, referring to FIG. 2E, the upper end of the bent first reinforcing bar 32 is vertically extended to connect with the second reinforcing bar 35 positioned above the first reinforcing bar 32.

When the concrete is hardened while the upper end of the second reinforcing bar 35 completely enters the interior of the second soundproofing wall 36, it is difficult to connect with the third reinforcing bar 37 positioned on the upper part of the second reinforcing bar 35. Because.

If the 3m high soundproof wall is used twice, the first stage soundproof wall 34 is 2m high and the second stage soundproof wall 36 is 1m high. have. In this case, the second reinforcing bar 35 is completely included in the second end sound insulation wall 36, and thus the shape of the second movable formwork is slightly changed.

After constructing the second stage sound insulation wall 36, the upper end of the bent second rebar 35 is vertically connected to the third rebar 37 positioned above the second rebar 35. The second reinforcing bar 35 and the third reinforcing bar 37 are connected in a stacking manner.

Next, the third stage sound insulation wall 38 is constructed by using a third movable formwork (not shown) and a concrete pouring device. The third movable formwork is manufactured to conform to the shape of the third stage sound insulation wall 38. The height of the third stage sound insulation wall 38 may be about 0.8 m.

By installing up to the third stage sound insulation wall 38, the height of the entire sound insulation wall including the first stage, the second stage, and the third stage sound insulation walls 34, 36, 38 can be 3 m. Since the third stage sound insulation wall 38 is the last, the third reinforcing bars 37 are completely contained in the third stage sound insulation wall 38.
