In assembling and constructing the manhole fixing box, it is very important to ensure watertightness because a gap occurs in the connection part of each structure as it directly causes leakage.

However, since the general manhole fixing box is manufactured by assembling after each component is separately manufactured as described above, there is always a risk of leakage through the connection portion of each component. In addition, since the same components are separately manufactured and assembled by a predetermined process, there is a problem in that the detailed orders of the consumer cannot be reflected.

For example, in the case of the manhole fixing box used in the wind power plant, the location and size of the waterproof tube are changed according to the design requirements, and according to the general manufacturing method, it is not possible to reflect these various requirements. Later, a separate water pipe was drilled. Such a manufacturing method has a problem in that efficiency is low, and there is a risk of leakage, and customer satisfaction is deteriorated because it cannot reflect the detailed requirements of the consumer.

According to a preferred embodiment of the present invention, the method for manufacturing a custom-made integrated manhole fixing box according to a preferred embodiment of the present invention may include a vertical sphere and a bottom sphere forming step (first step) and a side reinforcement step (second step). Step), internal formwork assembly step (third step), internal formwork seating step (fourth step), upper opening forming ring installation step (fiveth step), upper reinforcement step (sixth step), external formwork installation step (Seventh step), concrete pouring step (eighth step), and internal formwork disassembly and stripping step (ninth step).

In addition, the method for manufacturing a custom-made customized one-piece manhole fixing box according to a preferred embodiment of the present invention may further comprise a process, such as installing a waterproof cap, installation of a drag and a drag support, installation of a prefabricated top plate.

The first step is to form the vertical sphere 20 with reinforcing bars, and combine the vertical sphere 20 with the bottom sphere 10 while forming the bottom sphere 10 from concrete.

The bottom sphere 10 provides a space in which the inner formwork 40 can be seated, and supports the lower end of the vertical sphere 20. In addition, the bottom sphere 10 serves as a floor to close the bottom of the manhole fixing box when the manhole fixing box is completed.

The vertical sphere 20 serves as a skeleton of the entire reinforcement, including the side reinforcement 30 and the upper reinforcement 110, and is inserted into the concrete after the concrete is poured.

The second step is to further reinforce the reinforcing bar 30 to the vertical sphere (20).

At this time, the reinforcing bar further added to the vertical sphere 20 corresponds to the side reinforcement. The side reinforcement is further reinforced to the vertical sphere 20, thereby strengthening the bearing capacity of the vertical sphere 20 and can be opposed to the vertical load and the lateral pressure.

When reinforcing the side of the reinforcing bar 30, the prefabricated waterproof cap 70 is preferably installed so that the reinforcing bar is not positioned to secure the installation space of the prefabricated waterproof cap 70.

In addition, after the reinforcement of the side reinforcement (30) is completed, or during the reinforcement of the side reinforcement (30) is provided with a drag puller 80 and the drag support (90) at a predetermined position of the vertical sphere 20 and the internal formwork (40) .

When the mandrel 80 is completed, the manhole fixing box is exposed to the outside in the form of a ring, as shown in Figure 7, so that the manhole fixing box can be easily dragged.

The drag supporter 90 supports the drag 80 to be firmly coupled to the vertical sphere 20.

The third step is to assemble the inner formwork 40.

Referring to FIG. 3, the inner formwork 40 is assembled by combining a plurality of unit units 40a, 40b, and 40c. The plurality of unit units are formed in various shapes and standards, such as the unit unit 40a positioned at the corner of the inner formwork and the unit units 40b and 40c positioned in the planar portion of the inner formwork.

The reason for forming the internal formwork prefabricated by the combination of unit units is to facilitate the removal of the internal formwork through the top opening after concrete placement. If the internal formwork is formed integrally, a situation arises in which the internal formwork cannot be taken out through the upper opening of the manhole fixing box. However, when the internal formwork is formed by combining the unit units as in the present invention, the inner formwork is easily dismantled after disassembling only the coupling between the unit units, and the inner formwork may be taken out through the upper opening.

The fourth step is to insert the inner formwork 40 into the vertical sphere 20 to be seated on the upper surface of the bottom sphere (10).

When the inner formwork 40 is seated on the top surface of the bottom sphere 10 installs the prefabricated waterproof cap 70. The prefabricated waterproof cap 70 is installed at least one at a predetermined position of the vertical sphere 20 and the inner formwork 40, it can be freely combined in a variety of arrangements and a variety of waterproof caps as shown in Figs. The waterproof cap 70 is provided with a connecting protrusion and a connecting groove in the upper, lower, left and right, and adjacent waterproof caps may be combined in a free form.

In the case of the manhole fixing box, the location and size of the waterproof tube will vary depending on the design requirements. According to the general manufacturing method, it is not possible to reflect these various requirements. I'm doing it. This manufacturing method is inefficient, there is a risk of leakage, and customer satisfaction cannot help reflecting the detailed requirements of the consumer.

However, according to the method for manufacturing a custom-made customized one-piece manhole fixing box according to a preferred embodiment of the present invention, since it is manufactured in one piece, there is an advantage in that the number and position of the waterproof cap can be adjusted to meet the use of the orderer.

The fifth step is to install the upper opening forming ring 60 for forming the manhole on the upper end of the inner formwork 40.

The upper opening forming ring 60 forms a top opening to serve as a manhole when the manhole fixing box is completed.

At this time, a separate prefabricated top plate 50 is coupled between the upper end of the inner formwork 40 and the upper opening forming ring 60.

The prefabricated upper plate 50 has a shape in which the horizontal cross-sectional area becomes narrower toward the upper direction, and the corners are preferably chamfered to secure space.

By forming the prefabricated upper plate 50 in such a shape, the ability to withstand a large load of concrete is improved, and disassembly and removal are facilitated through a space secured between the concrete. The prefabricated top plate 50 is also preferably assembled from a combination of unit units in terms of disassembly and removal.

The sixth step is to install the prefabricated top plate 50 and the upper opening forming ring 60, and then reinforce the reinforcing bar on the upper formwork 40.

Referring to FIG. 5, the upper reinforcement 110 is disposed throughout the upper portion except for the region where the upper opening forming ring 60 is located. At this time, the upper reinforcement 110 in addition to the basic lattice structure in order to improve the load distribution and bearing capacity is preferably made of additional reinforcement to form a substantially rhombus shape around the ring 60 for forming the upper opening.

The seventh step is to install the external formwork 100 on the outside of the vertical sphere (20).

The eighth step is to cast concrete between the inner formwork 40 and the outer formwork 100.

The ninth step is a step of disassembling and removing the inner formwork 40 through the upper opening 120 (see FIG. 8) formed by the upper opening forming ring 60.

By disassembling the coupling between the unit units 40a, 40b, 40c as described above, the disassembly of the inner formwork 40 is performed, and the inner formwork dismantled into the separated unit unit falls out through the upper opening 120. Come out.
