Description

Concrete sewer pipe connection structure to prevent water pollution {CONCRETE DRAINPIPE CONNECTING STRUCTURE IN ORDER TO PREVENTING WATER CONTAMINATION POLLUTION}

The present invention relates to a concrete sewer pipe for preventing water pollution. More specifically, a concrete sewer pipe for preventing water pollution having a structure that can prevent leakage by using a rubber gasket in a concrete sewer pipe to prevent groundwater contamination. It relates to the connection structure.

In general, sewage pipes in the city center are buried in the ground using concrete culverts and concrete fume pipes. In this case, the concrete culverts are installed directly under the road and are often used as large main pipes. Hume pipes are used to connect sewage into roads, which are connected to large main pipes that are concrete culverts.

1 is a view showing a case in which a departure occurs in the conventional concrete sewer pipe structure, a plurality of concrete fume pipes 10, 20, 30, 40 is connected to the ground used as a sewage pipe, wherein the concrete fume pipe 20 and the concrete fume pipe 30, when the excessive load due to the earth pressure is transmitted from the upper portion is separated as shown in the drawing, whereby sewage leaking through the concrete fume pipe 20 and the concrete fume pipe (30) The case occurs.

The reason why the different reference numerals are given to the concrete fume pipe manufactured by the same structure is to clarify the description.

In the conventional sewage pipe connection structure, when the excessive earth pressure is applied from the upper part, the concrete fume pipe installed in the ground is frequently separated, so that the seam is separated, so that the sewage through the sewer pipe leaks to the outside of the sewage pipe and contaminates groundwater and soil. Had a problem letting.

The present invention is devised to solve the above problems, the present invention, by using the connection band, rubber gasket and fastening bolts at the joint of the concrete fume pipe can completely block the sewage leaking to the outside of the sewer pipe and thereby ground water Water pollution can be prevented as much as possible. In particular, the connection structure of the above-mentioned connection band rubber gasket and fastening bolt is easy, so it is easy to manufacture and construct at the joint of the concrete fume pipe, and concrete that can prevent soil and water pollution to the maximum. Its purpose is to provide a sewer pipe connection structure.

The present invention, in order to achieve the above object, the present invention is connected to a plurality of concrete fume pipe in the longitudinal direction is used as a sewage pipe in the connection structure of the sewage pipe made of concrete, while the above concrete fume pipe and other concrete fume pipe is coupled Installed in, the rubber gasket is inserted into the inside of the joint of the concrete fume pipe is in close contact with the water stopper; While coupled to the side of the joint portion of the concrete fume pipe, while one side is cut in close contact with the cut surface is formed with a small fixing bolt, a plurality of side connection portion is formed on the outer peripheral surface, the side connection portion A connection band having a through hole formed therein; And the concrete fume pipe provides a concrete sewer pipe connection structure for preventing water pollution, characterized in that consisting of a fastening bolt that is fastened tightly to the concrete fume pipe is fastened to the through hole of the close contact portion when the connection band is installed.

1 is a view showing a case in which separation occurs in the conventional concrete sewer pipe structure.

Figure 2 is a view showing a concrete sewer pipe connection structure of the present invention.

Figure 3 is an exploded state of the concrete sewer pipe connection structure of the present invention.

<Brief description of symbols for the main parts of the drawings>

50,52: concrete fume pipe 54: joint

55: rubber gasket 56, 58: connection band

60: side connection 62: through groove

64: close contact 70: fastening bolt

Hereinafter, with reference to the accompanying drawings will be described the configuration and operating state of the present invention.

2 is a view showing a concrete sewer pipe connection structure of the present invention, Figure 3 is an exploded state diagram of the concrete sewer pipe connection structure of the present invention.

As can be seen in Figure 2, the concrete fume pipe (50) (52) is connected to a plurality in the longitudinal direction is used as a sewage pipe, the concrete fume pipe 50 and the other concrete fume pipe (52) to explain the state of coupling For this purpose, only two concrete fume tubes are given reference numbers.

In the concrete fume pipe 50, a rubber gasket 55 is inserted into the inner side, while the concrete fume pipes 50 and 52 are connected to the connection bands 56 and 58 on the side of the outer joint, respectively. Fastening bolts 70 are fastened to the connection bands 56 and 58 to fasten each concrete fume pipe 50 and 52.

As can be seen in Figure 3, the structure that combines the above concrete fume pipe (50, 52), the rubber gasket (55) is in close contact with the inside of the concrete fume pipe (50) of one side and the other concrete fume pipe (52) It is located on the same line.

At this time, the connection bands 56 and 58 are respectively coupled to the joints to the concrete fume pipes 50 and 52, and the connection bands 56 and 58 are cut at one side thereof in a state of being cut. A close contact portion 64 is formed on the fastening bolts, and the connection bands 56 and 58 have a plurality of side connection portions 60 formed on the outer circumferential surface thereof, and through holes 62 in the side connection portions 60. ) Is formed.

The through-hole 62 is formed in the side connector 60 and the close contact portion 64, the fixing bolt (not shown in the figure) and the fastening bolt 70 is coupled, respectively, the fixing bolt and the fastening bolt Reference numeral 70 is used to give a different name because of the difference in length.

The connection bands 56 and 58 are used in a pair of two, and the shape and structure are the same.

When the connection bands 56 and 58 are installed in the concrete fume pipes 50 and 52, the fastening bolts 70 are fastened to the through-holes 62 of the close contact part 64, thereby providing the concrete fume pipes 50 and 52. While firmly in close contact with the rubber gasket 55 is coupled to the inside of the joint portion of the concrete fume pipe 50 formed on one side is connected to the other side of the concrete fume pipe 52 is connected to the connection band ( 56) 58 and the fastening bolt 70 has the advantage that the coupling force is exhibited to the maximum.

The effect of the configuration and operation of the present invention described above will be described.

The concrete sewer pipe connection structure for preventing water pollution of the present invention has the effect of providing a structure that prevents leakage as much as possible by using rubber gaskets, connecting bands and fastening bolts in the concrete sewer pipe to prevent groundwater and soil contamination. In particular, the above-mentioned concrete fume pipe can obtain the effect of preventing the leakage of sewage in its structure.
