In order to inspect and maintain the inside of pipes, machinery, facilities, etc. of such facilities, the thickness, direction, A manhole is a manhole that can be exposed to the ground at a place where the pipe is changed or a straight portion of a long pipe is set within a predetermined range according to the pipe diameter. Such a manhole is made of a concrete manhole and a PE manhole , And it is classified into a circular shape or a square manhole in terms of shape, and for the purpose of use, there are an upper and a sewer manhole, a communication manhole, a sewerage manhole (septic tank manhole), and a groundwater manhole.

In the lower part of the manhole, an inlet pipe and an outlet pipe are connected to allow the inflow and outflow of sewage. In the inner bottom, in order to suit the connection and connection situation of the pipe, usually 't', '', 'ten' And an inverter (invert) formed with a plurality of flow grooves (channels), which is made equal to the tube diameter and tilt of the tube, and the height thereof is slightly different, In order to prevent the accumulation and corruption of sludge contained in the sewage as well as to prevent the propagation of various insects such as odor by discharging the sewage quickly so that the sewage does not settle, the inflow pipe and the outflow pipe And a flow groove having a size corresponding to the semicircle of the semicircle.

The inlet port in the existing manhole is usually located on the upper side and flows along with the sewage accompanied by a bad odor caused by the dirt contained in the sewage flowing into the inlet port or a bad odor caused by the decay of the sewage which has been long- On the fall

The smell and sludge are scattered and diffused by the off-shore estuaries that hit the bottom, and the mildew environment in the manhole and the environment where the continuous inflow and outflow of sewage lead to the original smell of mold and scattered (scattered) There is a problem that the odor is mixed with the odor and causes more odor.

As shown in FIG. 1, an auxiliary pipe 3 is provided to prevent damage to the lower end of the manhole when the inflow water flowing into the inlet 2 of the manhole 1 falls downward, as shown in FIG. 1 is a cross-sectional view showing a structure of a right-and-left manhole provided with an auxiliary pipe according to a related art.

FIG. 3 is a cross- FIG. 4 is a plan view showing a drowning shock buffer member of a right and left manhole according to a first embodiment of the present invention. FIG.

2 to 4, the right and left manhole bodies 10 (10) and 10 (10) having an inlet (11) and an outlet (12) are formed on the upper and lower sides, respectively, (13) provided at the bottom of the right and left manhole body (10); And a drop-shock buffering member (100) which is seated on the mounting jaw (13) with an edge and disperses the dripping water introduced through the inlet (11).

The seating jaws 13 are formed at a predetermined height on the bottom surface of the right and left manhole bodies 10 and are formed with protrusions formed at regular intervals or in a circumferential direction.

The damping shock buffer member 100 is formed in the shape of a claw passing through the center portion, and an induction groove 110 for inducing the flow of the dripping water is formed. Here, the width of the guide groove 110 increases from the upper portion to the lower portion and is formed into a spiral shape.

Thus, the drowning impact buffering member 100 prevents falling directly to the bottom of the right and left manhole bodies. By forming the guide groove 110, the drowning water is guided to the guide groove and falls, The flow of water flowing through the impact buffer member is converted into a vortex shape (that is, the water is rotated) so that sediments inside the right and left manhole bodies can be swept down and cleaned.

Next, a drowning shock buffer member of a right and left manhole according to a second embodiment of the present invention will be described with reference to Figs. 5 and 6.

In the fluid inflow prevention unit thus configured, the falling water is prevented from being introduced by the upper fluid inflow prevention unit, and when the height of the water surface is gradually increased, the water impression fluid buffer member floats as the water surface increases due to its buoyancy, When the water surface of the fluid continues to rise and flows into the communication pipe, the opening and closing member 331 is pushed up by the water pressure and the other end touches the stopper 333, and the inflow of water is suppressed.

The connection pipe 342 of the upper fluid inflow prevention unit is connected to the connection pipe 342 of the upper fluid inflow prevention unit in a state in which the lower fluid inflow prevention unit suppresses the inflow of water to the maximum when the height of the water surface is raised even after the impression member 100 floated to the upper end, The upper gap between the connection pipe 342 and the communication pipe 310 is sealed by the sealing member 343 so that the inflow of the fluid is suppressed as much as possible.
