Description

[0001] The present invention relates to a repair socket for a drain pipe,

The present invention relates to an inspection port for maintenance of a stainless steel drain pipe connected to a bridge, an elevated driveway, and the like. The inspection pipe is provided with a drain pipe for easily connecting the cut stainless steel drain pipe, And a maintenance check port.

Generally, drainage pipes are installed and operated for discharging the road surface water of bridges and elevated roads in case of rain. Bridges and drainage pipes of high-altitude roads are piped using stainless steel pipes for durability and corrosion resistance.

However, in some cases, the drainage pipes for discharging road surface water from bridges and elevated roads are clogged by the accumulation of foreign matter such as gravels. In such a case, the road surface is flooded on the road surface, which hinders the safety of the facility and inconveniences the driver and pedestrian .

The drainage pipe is clogged, and the water penetrates into the pavement through the cracks at the time of the watering of the bridges and the elevated roads at the time of the accident. The concrete stays on the waterproof layer and causes deterioration of the concrete facilities, deterioration of the steel material, corrosion of the steel, Causing breakage.

In addition, there is a problem in that the driving ability of the vehicle is deteriorated due to the number of road surface water, and the freezing of winter occurs, resulting in a traffic accident.

Due to these problems, foreign matter accumulated in the inlet pipe of the drain pipe and the expansion joint is removed by periodic cleaning so as not to obstruct the drain pipe of the bridge or highway. However, when various foreign substances such as packing broken aggregate, soil, etc. are fixed in the drain pipe Cleaning is difficult to implement.

As described above, a pipe of a stainless steel material is used for durability and corrosion resistance of bridges and high-cost drainage pipes. The method of piping is to weld each pipe when connecting a straight pipe or a bent portion, do.

Therefore, if the inside of the drain pipe is clogged by the foreign matter, the clogged point is cut by a predetermined length to remove the foreign substances inside, and the cut pipe is welded again to finish.

Such repair work is not only inconvenient and time-consuming, but also poses a greater risk to workers because most work is performed at a high position

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an inspection port for maintenance of a drain pipe according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a perspective view showing a state where an inspection port for maintenance of a drain pipe according to the present invention is assembled, and FIG. 3 is a perspective view of a drain pipe maintenance according to the present invention. FIG. 4 is a partially enlarged perspective view showing a coupling surface of the first connection pipe and the second connection pipe; FIG. 4 is a partially enlarged perspective view showing a connection surface between the first connection pipe and the second connection pipe; FIG.

Generally, bridges and high drainage pipes are piped using stainless steel pipes for durability and corrosion resistance.

Stainless steel pipes are piped by welding each pipe when connecting a straight pipe or a bent part. When the inside of the pipe is clogged by a foreign substance, the blocked part is cut by a predetermined length to remove foreign substances The cut pipe was welded again and finished.

Such repair work is not only inconvenient and time-consuming, but also poses a greater risk to workers because most work is performed at a high position

In order to solve such a problem, as shown in FIG. 1, a check port for maintenance of a drain pipe according to the present invention comprises a cylindrical first connection pipe 101 and a second connection pipe 102, And the cap 110 is fastened to the threads 103 formed at both ends of the first connection pipe 101 and the second connection pipe 102.

The piping maintenance inlet 100 is formed with a first connection pipe 101 and a second connection pipe 102 each having a semicylindrical shape and covering a cut point of the drain pipe.

On the outer surfaces of both ends of the first connection pipe 101 and the second connection pipe 102, a thread 103 for screwing the cap 110 is formed.

The first connection pipe 101 and the second connection pipe 102 are wrapped around the cutting portion of the drain pipe to connect the first connection pipe 101 and the second connection pipe 102 in a cylindrical shape, And the cap 110 are screwed to both ends of the second connection pipe 102.

As shown in FIG. 3, the drain pipe 10 is cut to a length of about 50 to 100 mm for repairing the drain pipe 10, and the foreign substance in the drain pipe 10 is cleaned by the cut, And the second connection pipe 102, and the cap 110 is fastened at both ends thereof.

At this time, in the state where the rubber ring is inserted into the rubber ring seat 106 formed in a jaw shape at both ends of the first connection pipe 101 and the second connection pipe 102, 3, the compression ring 111 protruding axially inside the cap 110 is inserted into the rubber ring 105, as shown in FIG. 3, when the first and second connection pipes 101 and 102 are screw- And the rubber ring 111 is pressed between the rubber ring seat 106 of the first connecting pipe 101 and the second connecting pipe 102 and the pressing hole 111 of the cap 110, The outer surface of the water pipe 10 is compressed while being deformed to fix the water pipe 10 and maintain water tightness.

The watertightness of both ends of the first connection pipe 101 and the second connection pipe 102 is maintained by the rubber ring 105 as described above while the watertightness of both ends of the first connection pipe 101 and the second connection pipe 102 is maintained Sewage can leak through the surface.

In order to prevent this, as shown in FIG. 4, a watertight means is provided on a coupling surface of the first connection pipe 101 and the second connection pipe 102.

As shown in FIG. 4, the coupling surface watertight means of the first connection pipe 101 and the second connection pipe 102 are formed in the coupling surface where the first coupling pipe 101 and the second coupling pipe 102 are in contact with each other, And a water-retaining material 108 made of a rubber material having elasticity is inserted into the groove 107.

The water retaining material 108 may be made of a general rubber material, but preferably a water retaining material 108 molded with a water expansion index agent is used.

Since the water expansile index agent has a characteristic that the magnetic volume expands upon contact with water, watertightness due to the elasticity of the water retaining member 108 due to the engagement of the first connection pipe 101 and the second connection pipe 102 is maintained In addition, since the water expands upon contact with the sewage, it is possible to maintain the water tightness by the second water tightness.

The inspection hole 100 for maintenance of the drain pipe according to the present invention is made of high rigidity PVC to satisfy durability and cold resistance.

The piping maintenance port for maintenance of the present invention having the above-described structure can remarkably improve the workability and shorten the air because it can easily connect the cut piping when repairing the piping made of the stainless steel pipe.

Hereinabove, the access port for maintenance of the drain pipe according to the present invention has been described.

It will be understood by those skilled in the art that the technical features of the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

Therefore, it should be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than the foregoing description, Ranges and equivalents thereof are to be construed as being included within the scope of the present invention.
