Shall be.

1 is a perspective view showing a sliding foam system according to an embodiment of the present invention, Figure 2 is a side view showing a sliding foam system according to an embodiment of the present invention, Figure 3 is a sliding foam system according to an embodiment of the present invention It is sectional drawing shown. 1 to 3, the drainage path 1, the concrete 3, the sliding foam 10, the panel 12, the hopper 14, the steam passage 16, the steam inlet 18, and the steam outlet ( 20, drive motor 22, hot wire 24, electrical connector 26, vibrator 28 are shown.

This embodiment supplements the disadvantages of the existing prefabricated drainage method and formwork site casting method, by adding steam curing function to the sliding form moving forward in the longitudinal direction of the drainage, both sides of the drainage wall at the same time as the concrete input 80 degrees Celsius It is characterized in that the heating wire 24 is installed on the sliding foam panel so as to cure with steam (steam) of about 90 degrees, and to maintain a constant level without lowering the temperature in the concrete curing process.

In this way, by constructing and curing concrete while moving in the direction in which the drainage is to be installed, the construction of the drainage can be achieved, resulting in a reduction in construction period of more than 50% compared to the existing construction method, and a significant reduction in construction cost as the work efficiency is improved. There is an advantage.

On the other hand, in the past, a method for manufacturing a central separator while moving the formwork for the rapid construction of road facilities has been performed, but the central separator constructed using the mobile formwork as described above, the minimum time for curing concrete Since the condition was not satisfied, it was inevitable to construct with a mortar-type material with a very low slump value. This resulted in a lack of construction and sufficient structural rigidity of the constructed median. .

This embodiment is very good workability because the construction of the drainage by pouring a conventional ready-mixed concrete, and the poured concrete is cured by applying steam and hot wires 24, so that the slump value of concrete is immediately lowered immediately after pouring the sliding foam It is characterized in that the shape of the drainage path is maintained even if moved.

That is, the sliding foam system according to the present embodiment is a foam system used for the construction of the drainage extending in the longitudinal direction, the sliding foam 10 and the sliding foam 10 to form a space in which the concrete 3 is to be poured A hopper 14 serving as a passage so that the concrete 3 is poured into the space formed by the passage, a steam passage 16 for steam curing formed in the panel 12 constituting the sliding foam 10, and sliding It consists of a forward drive motor 22 for moving the foam 10 in the longitudinal direction.

Sliding foam 10 is a kind of formwork to form a space corresponding to the shape of the drainage, it can be produced by assembling the panel 12 of a predetermined thickness. In order to construct a drainage groove having a concave groove shape as illustrated in FIG. 1, the panel 12 may be assembled along the outline of the concave groove to manufacture another sliding foam 10 in this embodiment.

The hopper 14 is coupled to the upper portion of the sliding foam 10, and the concrete 3 is introduced into the space through an open top surface of the sliding foam 10 by injecting concrete 3 such as ready-mixed concrete through the hopper 14. Is poured. As a result, the drainage channel 1 structure is formed. However, in the case of conventional ready-mixed concrete, the slump value is often compounded to be easy to be injected through the hopper 14, that is, to improve workability. Thus, the concrete 3 having low slump value is contained in the space. In the case of pouring, as the sliding foam 10 moves, the poured concrete 3 may collapse and thus may not be able to maintain the drainage structure 1.

In order to prevent this, the sliding foam system according to the present embodiment is provided with a steam curing function. That is, a steam passage 16 through which steam can pass is formed in the panel 12 constituting the sliding foam 10, and a steam inlet 18 and a steam passage connected to the front end of the steam passage 16 are formed. Each of the steam outlets 20 connected to the distal end of 16 may be drilled into the panel 12 to allow steam to pass through the panel 12, thereby allowing the concrete 3 to be poured into the space to be steam cured.

For example, the sliding foam 10 according to the present embodiment, the thermal conductivity may be made of stainless steel excellent in thermal conductivity of 40% or more than the general steel plate, the structure of the sliding foam 10 can be steam (vapor) can pass through. It can be manufactured in a 'double structure' provided with a passage (16). In this case, by connecting the pipe connection of the steam boiler installed in a separate vehicle to the steam inlet 18 of the sliding foam 10 by applying steam of 80 to 90 degrees Celsius to the sliding foam 10 while continuously supplying steam, The injected concrete can be cured to maintain the shape of the concrete without sagging.

Furthermore, the heating wire 24 may be further installed in the sliding foam 10 according to the present embodiment, by supplying electric power to the heating wire 24 by using a generator installed in a separate vehicle. It is possible to compensate for the drop in steam temperature during the foaming process and to maintain the temperature of the sliding foam above a certain level.

In this way, while pouring concrete while curing the drainage path 1 while curing with steam and hot wire 24, while moving the sliding foam 10 at a predetermined speed by using the reduction motor 22 for the forward drive. Even if concrete is poured, the concrete can be completed while maintaining the shape of the drainage path 1 without falling down.

The steam passage 16 may be formed in various shapes such as a lattice shape, a letter shape, a ladder shape, as well as the shape shown in FIG. 2 so that the steam injected into the panel 12 may be evenly spread.

As such, by curing the concrete 3 with steam, the slump of the concrete 3 can be lowered within a sufficiently fast time, and the concrete 3 can maintain the shape of the drainage structure 1 even when the sliding foam 10 is moved. can do.

That is, the forward driving motor 22 for moving the sliding foam 10 in the longitudinal direction of the drainage channel may be coupled to the sliding foam 10 according to the present embodiment. As shown in FIG. 1, the driving motor 22 may be coupled to the base of the sliding foam 10, and the sliding foam 10 moves along the longitudinal direction of the drainage path by the driving force generated from the driving motor 22. do.

Therefore, even if a conventional ready-mixed concrete is placed in the space formed by the sliding foam 10, the concrete 3 can maintain the shape of the drainage path 1 structure by steam curing, and the sliding is driven by the operation of the driving motor 22. Even if the foam 10 is moved, the already constructed drainage passage 1 structure is cured while maintaining its shape, and the casting and curing work of the concrete 3 is performed again at the newly moved position, so that the drainage can be quickly flowed into a continuous process. (1) can be built.

On the other hand, even if the curing by supplying steam to the sliding foam 10, depending on the construction conditions, the temperature conditions for curing the concrete (3) may not be maintained, as a supplement to the panel 12 according to the present embodiment ), A heating wire 24 can be further installed.

That is, by embedding the heating wire 24 in the panel 12 constituting the sliding foam 10, by installing the electrical connector 26 to be connected to the heating wire 24, by connecting the power to the electrical connector 26, The heating wire 24 can be heated. In order to better transfer heat generated from the hot wire 24 to the concrete 3, the hot wire 24 may be embedded in the surface in contact with the concrete 3 of the panel 12 as shown in FIG. 3.

By applying heat to the concrete 3 additionally through the heating wire 24, it is possible to solve the problem of lowering the temperature in the curing process of the concrete (3), it is possible to maintain a constant temperature level required for curing the concrete (3) .

In addition, the vibrator 28 may be further coupled to the panel 12 according to the present embodiment. The vibrator 28 coupled to the sliding foam 10 may serve to make the poured concrete 3 more tight by vibrating the sliding foam 10 in the concrete 3 pouring process. The vibrator 28 may be installed at a suitable position to vibrate the panel 12, thereby further increasing the structural rigidity of the drainage passage 1 structure constructed by the sliding foam system according to the present embodiment.

If the existing gang foam (steel foam) is replaced by the double structure sliding foam according to the present embodiment under the same conditions, the curing period of concrete can be shortened not only in winter but also in normal weather, and thus the construction period can be shortened considerably. In addition, cost savings can be expected.

Figure 4 is a flow chart showing a drainage construction method according to an embodiment of the present invention, Figure 5 is a view showing a drainage construction process according to an embodiment of the present invention. Referring to FIG. 5, the drainage path 1, the concrete 3, the reinforcing bar 5, the concrete supply pipe 7, the sliding foam 10, the hopper 14, and the driving motor 22 are illustrated.

This embodiment is a 'steam curing drainage construction method' for quickly constructing a small drainage structure in a place where entry and movement of large equipment is difficult, such as a site under a road, and is not a mortar-type material as in the existing median construction. Even if the construction using the ready-mixed concrete (3) of the concrete (3) can be formed, it is characterized by the rapid construction is possible because the construction of the drainage while moving the sliding foam (10).

That is, in order to construct the drainage channel according to the present embodiment, first, the reinforcing bar 5 is placed and the bottom concrete is poured and cured (S6), and then the sliding foam 10 is installed at the starting position where the drainage channel is to be constructed ( S8). Since the structure and operation of the sliding foam 10 has been described above, a detailed description thereof will be omitted.

Next, the concrete 3 is supplied from the concrete pump car through the concrete supply pipe 7, and the supplied concrete 3 is poured into the space formed by the sliding foam 10 through the hopper 14 (S20). .

In the drainage construction method according to the present embodiment, while moving the sliding foam 10 in the longitudinal direction of the drainage (S10), the concrete (3) is poured and cured by molding the concrete (3) in the form of a drainage drainage (1) It is characterized by constructing a structure.

That is, the concrete 3 is continuously introduced into the space while the sliding foam 10 is driven forward by using the driving motor 22, and the vibration 3 and the concrete curing of the concrete 3 are performed in parallel to the concrete 3. ) And finish the construction of drainage (1).

Vibration compaction is a process of removing the voids of the concrete 3 poured in the space and keeping the concrete 3 closed by operating the surface vibrator 28 installed in the panel 12 to vibrate the sliding foam 10. (S26).

Steam curing, by pouring steam of about 80 to 90 degrees Celsius through the steam passage 16 formed in the panel 12 constituting the sliding foam (10) (S22), the concrete to be poured into the space (3) Is a process to cure. On the other hand, by installing a heating wire 24 further on the panel 12 to heat the concrete 3 (S24), the temperature of the concrete 3 during the steam curing process may be maintained to a certain level without lowering the above-mentioned Same as one.

The above-mentioned vibration compaction and steam (and hot wire) curing is a process that is performed during the movement of the sliding foam 10. Thus, by moving the sliding foam system, the concrete 3 is poured and cured to construct the drainage passage, thereby constructing the drainage. Speed can be significantly improved. Furthermore, by using steam curing while placing a conventional ready-mixed concrete without using a mortar-type material as in the existing median construction, it is possible to quickly construct a drainage with excellent durability.

In the case of the existing median type, the construction is done by placing mortar, so the density of the structure is low, so it is difficult to install it by using a pump car, so it is difficult to construct a long-distance structure, and the construction proceeds without curing. While cracking or sagging of concrete may occur, the sliding foam according to the present embodiment can be constructed by pouring ordinary concrete used in the field, so the durability of the structure is excellent, and remote construction using a pump car is also possible. As the curing progresses at the same time as casting, the concrete can be installed in winter without falling down during construction.
