Culvert assembly method using grouting tube {CULVERT ASSEMBLING METHOD USING GROUTING TUBE}

The present invention relates to a culvert assembly method, and more particularly, when assembling a culvert structure using a grouting tube, grouting for filling the grouting groove in the grouting groove formed in the culvert segment tightly to connect the culvert segment in the longitudinal direction. It relates to a culvert assembly method using a tube.

In recent years, culvert structures such as sewage culverts, electric power outlets, cavity holes, and aisle boxes are constructed by precast concrete (PC) in the factory, instead of being constructed by site-casting concrete. Prefabricated concrete culverts to assemble are widely used.

1 is a view showing a transverse coupling structure of the prefabricated culvert according to the prior art.

As shown in FIG. 1, the prefabricated culvert 10 according to the prior art is provided with protrusions 11 and recesses 12, which are fitted to correspond to each other at both end portions in the transverse direction, respectively, and the hollow sphere 13. The transverse reinforcement part 14 is formed in the edge of the inner wall surface which forms the, and the reinforcement part 14 is provided with the steel wire hole 16 into which the PS steel wire 15 is inserted.

Prefabricated culverts according to the prior art are assembled as follows and combined with each other. First, the builder fits the protrusions 11 of the front prefabricated culvert 10 into the recesses 12 of the rear prefabricated culvert 10 so that one end portion of the transverse direction in which the cavity sphere 13 is formed is interviewed with each other.

Thereafter, the PS steel wire connecting the two prefabricated culverts 10 to each other while the PS steel wire 15 is inserted through the steel wire hole 16 formed in the transverse reinforcement 14 of each prefabricated culvert 10. After fastening the cable fastener to one end of (15), and then tensioning the other end of the PS steel wire 15 using a separate cable tensioner, and then fastening the cable fastener to the other end, two prefabricated culverts ( 10) are combined with each other.

However, the transverse coupling structure of the prefabricated culvert 100 according to the prior art, which is adapted to couple two prefabricated culverts 10 interviewed with each other using the PS steel wire 15, has a disadvantage in that the PS steel wire 15 is easily corroded. In this case, when any one strand of the plurality of strands constituting the PS steel wire 15 is cut, the tensile force of the PS steel wire 15 connecting the prefabricated culvert 10 to each other in the transverse direction is lowered, resulting in ground subsidence. Or when an excessive load is applied to the prefabricated culvert 10 there is a problem that the prefabricated culvert 10 coupled to each other easily separated and separated.

In addition, the transverse coupling structure of the conventional prefabricated culvert 10 which fits the protrusion 11 of one prefabricated culvert 10 to the recess 12 of the other prefabricated culvert 10 is the prefabricated culvert 10 itself. When replacing the prefabricated culvert 10 due to the defect, since the joint surface of the two prefabricated culvert 10 is irregular, there is a problem that the replacement operation is difficult, in particular, the level of the uneven joint surface is poor Therefore, there was a problem in which a leak phenomenon easily occurs.

On the other hand, in the construction of connecting and joining a plurality of culvert segments composed of a prefabricated structure, a steel wire is provided to a sheath tube provided in the right angle part of each culvert segment in a state in which a plurality of culvert segments are normally connected to each other in a pipe direction. After passing through, the plurality of culvert segments are bonded to each other at the same time, and at the same time, a grouting material is formed at the joint between the culvert segments. For example, by filling and hardening a filler such as grouting mortar, the culvert segments adjacent to each other are integrally connected to each other.

However, the structure of connecting the culvert box through the tensioning of the wire and injecting the grouting material has a problem that leakage occurs easily when the wire is not functioning due to the loss of tension due to the aging of the wire during the use of the culvert segment. .

On the other hand, Figure 2 is a view showing a transverse coupling structure of the prefabricated culvert using a PC steel rod according to the prior art.
