Description

The present invention relates to a method for repairing an existing snow-melting nozzle buried in a paved surface such as a paved road.

[Conventional technology]

Conventionally, the existing snow-melting nozzle device has been repaired by removing the old snow-melting nozzle by scraping pavement materials such as concrete for snow-melting nozzle burying, asphalt, and installing a new snow-melting nozzle in its place, and then surrounding it again with concrete, asphalt, etc. It was carried out by the whole replacement method of fixing with paving material.

[Problems to be Solved by the Invention]

In the case of the repair performed by the total replacement method described in the above-mentioned conventional technique, there were defects such as large noise and vibration when the concrete was scrubbed, and the water supply pipe side was mistakenly damaged.

Therefore, a new repairing method is used, that is, a part of the existing nozzle device is left and a new part is attached to this remaining part, and by this installation, the road surface pavement material such as concrete and asphalt is newly piled on the old road surface. It has been found that it is desirable to adopt a construction method for forming a new road surface (hereinafter referred to as "bulkage construction method").

A weight body (58) with a handle (57) prepared separately is placed on the base (32) for use.

Thus, various types of the lid (a), one type of valve body (b),
Take various types of water control valves (c) and construction machinery (d) to the site, place the construction machinery (d) on the road surface where the existing snow-melting nozzle (e) is buried, and 58) and then the handle (3
5) Replace the grounding leg screw rod (33) (33) '(34)
Turn the knob to adjust the horizontal direction of the base (32), loosen the detent screw (39), and move the saddle (40).
Loosen the rotation stop screw (41) to rotate the rotary base (42), re-tighten the rotation stop screw (41), re-tighten the movement stop screw (39), and use the handle (44) to turn the electric drill body ( Adjust the height of 48) and align the center of the shank holder (50) with the center of the existing snow removal nozzle (b), and attach the ceiling wall cutting end mill (52) to this shank holder (50). The bottom blade (51) ′ of the ceiling wall cutting end mill (52) is the existing snow-melting nozzle.
Confirm by hitting the electric drill main body (48) with the handle (44) whether it hits a predetermined part of (e), and at this time, the bottom blade (51) of the ceiling wall cutting end mill (52) is
If it does not hit the existing snow removal nozzle (e) accurately, correct the position of the saddle (40), the orientation of the rotating table (42), and the position of the platform (32), thus cutting the ceiling wall. Check the tightening of the detent screw (39) and detent screw (41) after the end mill (52) is correctly positioned.

Next, operate the handle (44) to cut the ceiling wall end mill.
The bottom blade (51) ′ of (52) is lightly applied to the upper surface of the top wall (61) of the existing snow-melting nozzle (e), and in this contacting state, the slide gauge (56) is moved up and down. The zero point is aligned with a reference point (not shown), and then the handle (44) is returned and the bottom blade (51) ′ of the end mill (52) is attached to the top wall (6) of the existing snow removal nozzle (e).
1) away from this, and in this separated state, the electric drill main body (48) is rotated and the handle (44) is operated to lower the end mill (52), and the ceiling of the existing snow removal nozzle (e) is lowered. Wall (6
Cut the center part of 1) into a circle with the old water spray holes (62) left. Whether or not this cutting has been sufficiently performed is determined by the scale of the slide gauge (56) with the zero adjustment described above.
Checking the descending amount of (45), it is confirmed by a means to know that the cutting depth has reached a predetermined dimension.

After that, stop the electric drill body (48) and return it to the upper position, and attach the ceiling wall cutting end mill (52) to the shank holder (50).
The pliers (not shown) by removing the parts enclosed by the circular cutting (64) and the built-in components (65) such as old valves.
To remove.

Further, attach a pilot hole drill (53) to the shank holder (50), rotate and lower the pilot hole drill (53) to lower the bottom of the case (66) of the existing snow removal nozzle (e). Pilot hole
Drill (67).

Then, using the tap (54) in the pilot hole (67), the connecting female screw (6
8) Engrave. In this engraving work, the tap (54) is rotated by using a built-in wrench (69) for reverse rotation stop mechanism (not shown) which is a one-handed rotation, and a short round bar pin (pre-installed on the wrench (69) ( 7
(0) is rotatably fitted to the shank holder (50) to prevent head movement.

After that, remove the tap (54) and wrench (69) from the shank holder (50) and attach the boring end mill (55) to the shank holder (50).
Using the (55), the old water spray hole (6
Cut off the top wall including 2).

In this way, the processing for the existing snow-melting nozzle (e) is completed.

Then, the valve body (b) and an appropriate water control valve (c) are previously combined into the space (71) formed by removing the built-in object (65) such as the old valve, and then the second valve is inserted. The male screw (12) is screwed into the connecting female screw (68). After that, the lower edge of the lid (a) is twisted into the space (71) and pushed in, and the outer peripheral surface of the first O-ring (4) is attached to the peripheral wall surface of the space (71) to the second side. The outer peripheral surface of the O-ring (22) is hermetically pressed against the inner surface of the inner peripheral wall portion (6) of the lid (a), and the first male screw (11) is screwed onto the first female screw (2). Together with the existing snow-melting nozzle (e), the entire peripheral edge of the opening of the space (71) in the existing snow-melting nozzle (e) and the outer peripheral surface of the outer peripheral wall portion (7) of the lid (a) are hermetically welded together. After forming a new part (f) on the top of the existing road surface (old road surface) (73), a new road surface (74) with new pavement materials such as concrete and asphalt
Is used to complete construction.

The present invention may be carried out without providing the first O-ring (4) or without welding the lid (a) to the existing snow removal nozzle (e).

〔The invention's effect〕

Since the snow-melting nozzle repairing method of the present invention has the above-described structure, it is possible to carry out the bulking-up method by performing the construction means described above. The noise and vibration of the
In addition, the water supply pipe side is prevented from being accidentally damaged and has an excellent effect that the intended purpose can be sufficiently achieved.
