The present invention relates to a method for repairing the inside of a water collector in order to prevent water from entering through the palate joint of a manhole and gas leaking from the palate joint.

施されている。
In existing gas piping, in the case of conventional gas supply, a water collector is installed in the middle of the gas piping in order to prevent water contained in the gas from separating and accumulating in the gas pipe. However, unlike traditional gas, recent city gas does not contain water, so the water collectors mentioned above are not necessary, but existing gas piping systems already have water collectors that are no longer needed. Therefore, measures have been taken to prevent gas leakage from this unnecessary water collector.

ている。 Conventionally, as one of the countermeasures, for example, as shown in FIG. 6, the inside of the water intake standpipe 12 installed in the center of the water intake manhole 11 is filled with epoxy resin to seal the inside of the pipe. A disposal method has been proposed, and a known prior art of this type is the one described in Japanese Patent Publication No. 54-32964.

In the case of the above-mentioned disposal method, even if gas leakage through the water intake standpipe 12 can be completely prevented, the problem here is that the palate joint that fixes the palate 13 of the water intake manhole 11 Due to deterioration of the seal in the
From this part, groundwater in the soil flows through the water collector manhole 1.
There were problems such as gas entering the tube or leaking from the above-mentioned palate junction.

When a ring-shaped seal member is simply brought into close contact with the conventional method, there is a problem in that the seal cannot be reliably repaired.

In order to achieve this object, the present invention provides the following features: (A) A water catcher installed in the middle of an existing pipe, where the joint of the palate is fixed to the upper opening of the manhole of the water catcher. (B) A sealing gasket that is tightly attached to the inside of the joint edge of the manhole cover is formed into an annular body with a diamond-shaped cross section using a flexible material impregnated with an adhesive; C) With this annular seal gasket facing and supported inside the joining edge of the palate, the gasket is expanded radially from the annular inner circumferential side using an expandable pressing ring having a trapezoidal outer surface. By pressing it upward, the annular seal gasket will come into close contact with the corner of the palatal joint edge from the outer peripheral corner of the upper surface side, and the upper surface will gradually close while expelling the air stagnant at the corner. This repair method is characterized by repairing the inner surface of the palate by deforming its cross section so that the outer circumference side is in close contact with the inner surface of the manhole mouth and sealing the palate joint edge. When gluing a seal gasket from inside the water collector manhole so as to seal the inside surface of the joint of the roof of the mouth, the seal gasket is first attached to the outer circumferential corner of the top side, and then to the corner of the joint of the roof of the mouth. The cross section is deformed so that the upper side is in close contact with the inner surface of the palate and the outer circumferential side is in close contact with the inner surface of the manhole opening, so as to expel the air stagnant at the corner of the manhole. This prevents air from being trapped in the corners of the joint, allowing reliable seal repair.
以下、本発明の一実施例を図面に基いて具体的

シールガスケツト６が載せられている。 In the figure, reference numeral 1 denotes an annular support stand, on which a C-shaped pressing ring 3 is placed in a state of being reduced in the inner diameter direction by a turnbuckle 2. The pressing ring 3 has an outer surface formed into a trapezoidal shape, and the inner surface thereof is provided with lugs 4, 4 for hooking the ends of the turnbuckle 2. A pressing rubber ring 5 having a V-shaped cross section is placed on the support base 1 on the outer surface side of the pressing ring 3. The rubber ring 5 forms a diamond-shaped cross section and is bonded with epoxy resin or the like. An annular sealing gasket 6 made of a porous flexible material impregnated with an agent is placed thereon.

ように上昇させる（第２図、第３図参照）。 When repairing the inner surface of a water catcher, first place the pressing ring 3, pressing rubber ring 5, and annular seal gasket 6 on the above-mentioned support base 1 from the inside of the water collecting manhole 7 and supporting them. The seal gasket 6 is attached to the upper opening edge 7a of the water collector manhole 7.
It is raised so as to face the inside of the joining edge of the palate 8 which is joined and fixed to the palate (see FIGS. 2 and 3).

４図参照）。 Next, from this state, the turnbuckle 2 is operated to expand the pressing ring 3 in the radial direction. As a result, the pressing rubber ring 5 is expanded in the radial direction on the outer surface (trapezoidal shape) of the pressing ring 3, and the rubber ring 5 is expanded in the radial direction.
is elastically deformed to follow a trapezoidal shape, and the annular seal gasket 6 on the outer circumferential side is also deformed in cross-section and brought into close contact with the corner of the palate joint (see FIG. 4).

口蓋接合部の内面に密着させることができる。 In this case, the seal gasket 6 is made of a flexible material and is formed into an annular body having a rhombic cross section, and is pressed from the inner circumferential side and is expandable and has a trapezoidal outer surface. Since the annular seal gasket 6 is expanded in the radial direction with the ring 3 and pressed upward, the annular seal gasket 6 first has its outer peripheral corner on the upper surface side first, and then touches the corner of the palate junction. The upper side of the palate 8
The cross section is deformed so that the outer circumferential surface side is closely attached to the inner surface of the opening of the manhole 7, and the seal gasket 6 is bonded to seal the palate joint. The sealing gasket 6 can be reliably brought into close contact with the inner surface of the palate junction without causing the phenomenon that gaskets are trapped.

When it is completely solidified, the turnbuckle 2 is operated again to reduce the diameter of the pressing ring 3, and the support base 1, pressing ring 3, and rubber ring 5 are removed in this order as shown in FIG.

According to the present invention, since the sealing gasket is adhered to seal the palate joint of the water collector manhole by the repair method described above, it is possible to prevent damage inside the water collector manhole due to seal deterioration at the palate joint. Problems such as groundwater infiltration and gas leakage from the palate junction can be solved.
