The present invention relates to a waterproof block for a manhole, and more particularly, to configure a waterproof block and a height adjusting block to enable a watertight structure inside a manhole, to prevent corrosion of gas pipes and gas valves. will be.

1 is a cross-sectional view showing a general manhole structure, Figure 2 is described together as an exploded perspective view showing the upper part of the body in the general manhole structure.

In general, when embedding a gas pipe for transporting gas, such as city gas in the ground, the manhole 10 is constructed for maintenance of the gas pipe so that the gas pipe 30 penetrates the manhole 10. .

However, the gas valve 30 and the gas valve 40 mounted on the gas pipe 30 may cause a huge explosion when the gas leaks due to corrosion, so that each engine is watertight inside the manhole 10. Is strictly regulated by law.

Therefore, the structure of the general manhole 10 is configured to be watertight, looking at the structure as follows.

Pedestal 50 fixed to the upper body 20 of the manhole 10 made of concrete and the inner lid 60 and the inner lid 60 to cover the upper portion of the body 20 in the pedestal 50 The outer lid 80 is formed to cover the upper portion of the pedestal 50 by forming a space between the lock 70 and the inner lid 60 to apply water pressure to).

Looking at the structure in more detail, the pedestal 50 is generally cylindrical in shape, spaced apart from the inner wall of the pedestal 50 to receive the water pressure from the inner lid 60 on the inner bottom of the annular hydraulic portion 52 protruding upwards ) Is formed, the pressure receiving portion 52 is configured to cover with a packing 53 for watertight, the inner wall is formed with support projections 51 facing each other for mounting of the lock (70).

The inner lid 60 has a plate shape in which a central portion is recessed, and a flange 63 contacting the packing 53 of the hydraulic portion 52 at the outermost portion is provided, and the hydraulic pressure is provided by a bolt or the like to receive the hydraulic pressure at the center of the upper surface. A plurality of handles 62 are provided around the support 61 and the hydraulic support 61.

Therefore, the flange 63 of the inner lid 60 is positioned in the packing 53 of the hydraulic part 52 of the pedestal 50, and then a rod-shaped locking rod hinged to the lever 71 in the center ( Both ends of the 70 are positioned below the support protrusion 51 of the pedestal 50.

In addition, the flange 63 of the inner lid 60 is pressurized by rotating the lever 71 so that the hinge engaging portion 72 of the lever 71 compresses the hydraulic support 61 of the inner lid 60. The packing 53 of 52 is pressed and watertight is possible.

Therefore, in order for the worker to open the inner lid 60 and enter the manhole 10, there is a hassle of having to pump out water using a gourd or the like. However, since the work of pumping water is often troublesome, the inner lid 60 is often opened as it is, so that water flows into the manhole 10 and the gas pipe 30 and the gas valve 40 are corroded.

In addition, since water is always accumulated in the space between the inner lid 60 and the outer lid 80, it becomes a habitat for pests such as mosquitoes, and becomes a breeding ground for diseases, and the water is not only polluted, causing rotting.

And when the maintenance work because of the contaminated water, there is a lot of inconvenience in the operation because the handle 62, the locking table 70 of the inner lid 60 is not visible, if the water freezes in winter, The hassle of crushing the ice usually delays maintenance work, causing large explosions.

Accordingly, in the present invention, by introducing a manhole waterproof block into the space between the inner lid and the outer lid, the inflow of water, such as rainwater, is blocked at the source to prevent corrosion of the gas pipe and the gas valve in advance. It does not need pumping work, so the maintenance work of the worker is easy, so the purpose of preventing a large explosion accident.
