Description

Drainage Pipe Formwork

The present invention relates to a drainage pipe formwork mainly used in civil engineering or road construction.

In general, concrete hume pipes, synthetic resin spiral pipes, corrugated steel pipes, etc. are used for drainage pipes. The problem with on-site use is concrete fume pipes, which have good external pressure strength as rigid pipes, but are difficult to construct. Difficulty solving leaks In addition, the spiral tube made of synthetic resin has a light weight and good workability, but has low external pressure strength, and it is difficult to solve the problem of leakage at the connection site. Although steel pipes have good workability and external pressure strength, there is a problem that the corrugated iron core is rusted and broken when used for a long time.

Therefore, the external pressure strength and the cross section of the product is insufficient to provide a product that can completely solve the problem of leakage of the T-shaped connection portion.

As to the product to solve the above point, there is a technical problem to efficiently provide the drainage pipe with the structure of the complete leakage prevention structure of the external pressure and the connection part of the product that can be used in the construction site.

As a formwork for drainage pipes provided to solve the above-described problems in the present invention, it provides durability, impact resistance, and construction properties, which are advantages of synthetic resin spiral pipes, and provides external pressure and rigidity, which are advantages of concrete fume pipes. When described according to the drawings designed to provide a formwork for drainage pipes to prevent leakage.

In order to explain the object described in the present invention to fill a certain space, that is, cement mortar (6) on the inner surface (3) and the outer surface (4) consisting of a spiral winding as shown in Figures 1 to 4 In the pipe of the two-layer structure in which the input space 5 is formed, the outer surface 4 is intermittently bent to the inner surface 3 side in the spiral winding direction and integrated into the groove coupling table 2, but the groove coupling table ( 2) It is a product about drainage pipe formwork formed to form spiral wound cement mortar (6) input space (5) between.

Here, in order to reinforce the external pressure reinforcement and robustness of the drainage pipe of the present invention, the outer reinforcing rod 8 is inserted into the outer side 4 to the outer side as shown in FIG. It provides external pressure reinforcement in the structure according to the formation of the quasi-grooved coupling 2.

In addition, as an embodiment of the outer surface 4 in the present invention as shown in Figure 6 and Figure 7 the cement mortar inlet 7 in the input space 5 of the present invention described above in one direction, that is, the upper side It is designed to provide a drainage pipe (1), which is formed on the site, and is constructed according to the drainage pipe at the construction site, and then filled with cement mortar (6) in the input space (5) through the inlet (7) for curing for a certain period of time. to be.

At this time, the groove engaging table 2 located in the inlet 7 is left on the inner surface 3 as the engaging table 2 'in the cut state.

And, in order to provide a T-type drainage pipe formwork connecting the auxiliary formwork (1 ') to one side in accordance with the conditions of the construction site in the drainage pipe formwork (1) of the present invention as shown in Figure 8 and 9 In the formwork 12 for the auxiliary formwork 1 'on one side of the inner side 3 and the outer side 4 of the tubular die 1 and the inner side 3 and the outer side of the auxiliary formwork 1'. After joining (4), respectively, it is devised to provide a formwork for drainage pipes in which cement mortar 6 is injected into the inlets 7 and 7 'and filled in the internal space 5 to cure.

In addition, the inlet formed in the outer surface (4) of the drainage pipe formwork (1) of the present invention as shown in Figures 10 and 11 as a devised for providing a drainage pipe suitable for road passage or ground drainage pipe passing through soft ground. (7) is formed intermittently in the entire area of the outer surface mortar coupler (7 ') to provide a drainage pipe for the bridge 10 through the road (9) to provide the cement mortar (6) of the road (9) It is provided with a drainage pipe configured to be put in a predetermined section, such as the bridge (10).

The present invention is a formwork for drainage pipes, which is designed to be lightweight, constructive, which is an advantage of synthetic resin spiral pipe, and to strengthen the strength and external pressure reinforcement, which is an advantage of concrete fume pipes. .
