Description

A connection structure connecting a manhole and a sewage pipe {An earthquake-resistant manhole structure}

The present invention relates to a connection structure connecting a manhole and a sewage pipe, and more particularly, by constructing a cast iron pipe elastically in a manhole and installing a cushion band at an end of the cast iron pipe to elastically connect one end of the sewer pipe. It relates to a connection structure connecting a manhole and a sewage pipe, which can prevent damage caused by an earthquake and elastically support the sewer pipe in the ground to maintain a stable posture.

In general, manholes require sewage pipe construction to treat rainwater, sewage, wastewater, etc. in various civil engineering and construction works. It is a means of providing a kind of space to perform roles such as joining and branching.

After such a manhole is constructed in a state buried in the ground, a drain pipe for drainage is connected to one or both sides of the lower circumference.

At this time, the manhole is a concrete structure, and the drain pipe is generally made of a concrete hume pipe or plastic, usually PVC or PE.

Then, the drain pipe is assembled as shown in the example of FIG. 1 . For example, as shown in FIG. 1, a drain hole 2 is formed at the bottom of the manhole wall 1, a drain pipe 3 is inserted into the drain hole 2, and the drain pipe 2 is inserted around the drain hole 2. It is filled with mortar (4) to prevent leakage.

On the other hand, earthquakes are divided into P-waves shaking in the longitudinal direction, S-waves shaking in the transverse direction, and L-waves in which P-waves and S-waves occur simultaneously to transmit energy. The manhole is also shaken, and in particular, since the drain pipe (3) inserted into the manhole wall (1) is not seismically designed, it is shaken alternately with the manhole wall (1), causing the drain pipe (3) and mortar (4) to be connected to the drain pipe. is easily damaged, resulting in a problem of separation and separation.

Accordingly, manholes equipped with various types of earthquake-resistant structures have been disclosed, but they are limited to the degree of improvement that is merely a transformation of a simple connection structure and are not known.
