DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, with reference to the accompanying drawings, a method of installing a "J" -type downhole waterway pipe and a movable formwork according to the present invention will be described in detail with reference to embodiments.

Generally, the "J" type water pipe is a drain disposed along the longitudinal direction of the road for collecting and draining water on the road surface or its adjacent slope. The present invention relates to a water- While providing a soundproof wall installation method that requires a low construction cost. Concrete pouring equipment is equipment that is used in conjunction with movable molds that form a soundproof wall structure. For example, there is a device called a slip-form paver. In operation, the movable mold is moved with the concrete pouring device, where the concrete pouring device moves the concrete pouring into the movable mold.

1 to 3 sequentially illustrate the installation process of the "J " -type downhole channel according to the embodiment of the present invention. In the first step, as shown in FIG. 1, a movable mold and a concrete pouring device So that the water pipe main body 1b is laid primarily in conformity with the height of the first upper projecting portion 1c. Here, the above-mentioned main body 1b of the water pipe is laid directly on the lower side of the "J " -shaped type with a movable formwork and a concrete pouring apparatus without reinforcing bars.

The second step is to form the reinforcing bars 1a on the upper surface of the other side water passage main body 1b of the first upper projecting portion 1c of the water channel main body 1b in the curing process before the water channel main body 1b is completely hardened as shown in FIG. ) To cure it. In the third step, when the channel body 1b in which the reinforcing bar 1a of the second step is completely hardened, the second upper protruding portion 1d is formed by using a movable die and a concrete pouring apparatus so as to surround the reinforcing bar 1a Thereby completing the construction of the "J" type port side waterway pipe 1 as shown in Fig.

Figure 4 is a rear view of a mobile formwork in which a "J " type portlet conduit is laid using a movable formwork, the movable formwork 3 being a formwork < . The concrete pouring device 2 can inject concrete into the movable mold 3 through the concrete conveying device 2a. The movable mold 3 is connected to the concrete pouring device 2 and moves together when the concrete pouring device 2 moves. The concrete pouring device 2 moves while continuously injecting the concrete into the movable mold 3 through the concrete conveying device 2a and the injected concrete is conveyed through the movable mold 3 to the side of the "J" Shape.

5 and 6, the movable mold 3 includes first and second installation portions 31, 32, a front portion 37, and a rear portion 38, The poured portions 31 and 32 have an open space into which concrete is injected. When the first projecting portion 1c is installed using the concrete pouring device 2, the first and second pouring portions 31a and 31b are connected through the concrete conveying device 2a connected to the concrete pouring device 2 as shown in Fig. (32). ≪ / RTI >

The front portion 120 is integrally connected to the front of the first and second placement portions 31 and 32. When the movable mold 3 connected to the concrete pouring apparatus 2 moves, the front portion 37 becomes the first contact portion with the reinforcing bar 1a. The front portion 37 is provided with a front interior 37a protruding to fit the shape of the first projection 1c. The rear portion 38 is integrally connected to the rear of the first and second placement portions 31 and 32. When the movable mold 3 connected to the concrete pouring apparatus 2 moves, the concrete injected into the first and second putting portions 31 and 32 passes through the rear portion 38 while the shape of the first projecting portion 1c And the rear portion 38 is provided with a rear interior 38a which is protruded in conformity with the shape of the first projection 1c.

A completely open passage is formed from the front interior 37a to the rear interior 38a with a cross-sectional shape of the first projection 1c. Therefore, when the movable mold 3 connected to the concrete pouring apparatus 2 moves, the reinforcing bar 1a is guided by the front interior 37a while the front portion 37 progresses, . At this time, the concrete is injected into the first and second installation portions 31 and 32, and then, after passing through the inside of the rear wall 38a, the concrete is completely shaped in the shape of the "J" type side channel conduit 1.

The first and second installation portions 31 and 32 are divided into two portions by the first and second partitioning portions 33 and 33a and the first and second sections 31a and 32a. The first and second partitioning portions 33 and 33a extend in the longitudinal direction in the first and second placement portions 31 and 32 as shown in FIG. 6, but do not extend completely to the bottom. This is because the concrete is filled in the bottom of the first and second installation portions 31 and 32 so as to conform to the shape of the "J"

The concrete is injected into the first sections 31a and 32a of the first and second installation portions 31 and 32. [ Concrete injected into the first sections 31a and 32a does not pass directly to the second section 39 by the first and second partitioning sections 33 and 33a. The concrete injected into the first sections 31a and 32a is gathered by vibrations of vibrators (not shown) mounted on the first vibrator mounts 34 and 34a and the second vibrator mounts 34 and 34a, And then passes to the second section 39 through the space under the first and second partitioning sections 33 and 33a. The concrete passed to the second section 39 is further strengthened by the vibration of the vibrator (not shown) mounted on the third vibrator mounts 36 and 36a.

The first vibrator mounts 34 and 34a are attached to the first and second partition members 33 and 33a and extend toward the center of the first sections 31a and 32a. The second vibrator mounts 35a and 35b are attached to the wall surfaces of the first sections 31a and 32a and extend toward the center of the first sections 31a and 32a. The third vibrator mount 36 (36a) is attached to the wall surface of the second section 39. The first vibrator mounting portion, the second vibrator mounting portion, and the third vibrator mounting portion are mounted with vibrators, which function to improve the density of the concrete.

It is necessary to attach vibrators only to the wall surfaces of the first and second installed portions 31 and 32 without the first and second partition portions 33 and 33a, The vibration caused by the vibrator attached to the first and second installation portions 31 and 32 is hardly transmitted to the center of the first and second installation portions 31 and 32. As a result, the concrete is not sufficiently consolidated and the quality of the "J "

In the present embodiment, a vibrator can be mounted on the first vibrator mounting portions 34 and 34a attached to the first and second partition portions 33 and 33a, and the vibrations of the first and second mounting portions 34 and 34a 31) 32 can be sufficiently made as a whole. The concrete injected into the first sections 31a and 32a does not pass directly to the second section 39 by the first and second partitioning sections 33 and 33a but is sufficiently thickened by the vibration of the vibrating section The density of the concrete can be further improved because it passes through the space under the first and second partitioning parts 33 and 33a to the second section 39. [

The guide rods 39 and 39a may be installed transversely across the first sections 31a and 32a to guide both sides of the reinforcing bar 1a. The guide rods 39 and 39a prevent the reinforcing bars 1a from moving when the movable mold 3 moves. The guide rods 39 (39a) can also extend to the front portion 37 and the rear portion 38.

Thus, according to the present invention, the concrete injected into the first section by the first and second partition portions and the first vibrator mounting portion attached to the first and second partition portions can be sufficiently compacted, thereby enabling the use of the movable formwork and the concrete pouring machine It is possible to install the soundproof wall by the conventional method, and it is possible to cut the time and cost for the construction of the soundproof wall by half compared with the conventional method without requiring a work step requiring a lot of time and manpower, such as form installation and demolition. In addition, since the guide rod prevents the movement of the reinforcing bars, it is not necessary to use a complicated and time-consuming method as in the past in order to prevent the movement of the reinforcing bars.

Although the method of installing the "J" -type downhole waterway pipe and the movable formwork according to the present invention have been described in detail, the present invention is not limited thereto and only the most preferred embodiments of the present invention are described. The range is determined and limited by the claims. It will be apparent to those skilled in the art that various changes and modifications can be made by those skilled in the art without departing from the scope of the present invention.
