Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sprinkler nozzle device for snow melting on a road, which is mainly used for a raising method for repairing a snow melting nozzle buried in a paved surface such as a paved road or a sidewalk.

[0002]

[Prior art]

(Prior art) Conventionally, the snow-melting nozzle was repaired by shaving the concrete for burying the snow-melting nozzle using a concrete crusher or a concrete cutter to remove the entire old snow-melting nozzle, replacing it with a new snow-melting nozzle, and surrounding it. It was done by the whole replacement method of fixing the concrete with concrete. However, in the case of the whole replacement method, noise and vibration during concrete hardening are large, a long curing time is required until the concrete hardens, traffic regulation is required during curing, and repairs performed in winter Since concrete is hard to solidify in cold temperatures, there is the inconvenience that the curing time and traffic regulation time will be longer, and the road width will be narrow for a long time during construction due to snow on the roadside, which is a danger level. Was extremely high.

Further, as a means for eliminating such a defect, Japanese Patent Laid-Open Publication No. 4-141252 discloses a bulking repair method. A construction completed by this construction method is shown in FIG. 8, which has the following new parts. That is, the first female screw 42 is engraved on the lower end of the inner peripheral surface of the short tubular member 41 longer than the bulk dimension, and the deep annular groove 45 is formed on the bottom surface of the short tubular member 41.
To form an inner peripheral wall portion 46, an outer peripheral wall portion 47, and a ceiling wall portion 48.
And the outer periphery of the upper and lower end portions of the short thin tube 50, which are formed by forming water spray holes 49 at both ends of the upper and lower portions of the top wall portion 48, which are open at both upper and lower sides of the top wall portion 48. The first male screw 51 and the second male screw 52 are similarly engraved with the second female screw 53 on the inner periphery of the upper end portion, and the water introducing fixed side hole 5 communicating with the inside and the outside at the intermediate height position of the thin tube 50.
4 and a valve body B configured by opening 4, and a shallow water guide hole 57 is formed in the center of the lower end surface of the rod-shaped member 56, and a movable water guiding hole 58 is opened in the peripheral wall of the hole 57 inward and outward. At the same time, a third male screw 59 screwable with the second female screw 53 is formed on the outer periphery of the intermediate height of the rod-shaped member 56, and a driver groove 60 is also formed on the upper end face of the rod-shaped member 56. The second packing groove 61 is formed by engraving the second packing groove 61 on the outer peripheral portion above the third male screw 59.
And a water control valve C configured by fitting a second O-ring 62 on the existing road surface (old road surface) 6
4, a new road surface pavement material such as concrete or asphalt is overlaid to form a new road surface 65, which is thus buried.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to the drawings. First, a magnetic metal plate base 71 with a hand handle 70 is vertically penetrated through both front and rear central portions. Screw holes (not shown) are provided, and both of the front screw holes and the rear screw holes have landing leg screw rods 72, 73, 74 with both upper and lower ends thereof protruding both above and below the base 71. The handle 75 is detachably attached to the upper ends of the landing leg screw rods 72, 73 and 74, and the floating floats 76 and 77 are attached to both sides of the rear edge of the base 71 to mount the base 78. And laid on the base 71
Equipped with a saddle 81 with a detent screw 80 so as to be movable in the front-rear direction via a rotary base 83 with a rotation stop screw 82 on the saddle 81, and a machine base 84 on the rotary base 83. A slide head 86 that slides up and down by a handle 85 and a rack mechanism (not shown) is mounted on the front surface of the base 84, and an electric drill main body 90 is attached to the slide head 86 downward via a mounting bracket 87 and mounting screws 88 and 89. A shank holder 92 is provided at a lower end of a main shaft 91 of the electric drill main body 90. The shank holder 92 has a ceiling wall cutting end mill 95 having blades 93 and 94 on an outer circumference and a bottom surface of a cylinder, and a drill 96 for drilling a prepared hole. , The tap 97 and the boring end mill 98 can be arbitrarily replaced so that the slide head 8 can be mounted on the machine base 84. The next to provide a vertical movement amount measurement slide gauge 99 of the slide head 86 as vertically movable, and weights body separately with the handle 100 from this 101
Of the weights 10 on the base 71.
A construction machine 102 for mounting and using 1 is constructed.

In this way, the construction machine 102 is placed on the road surface in which the existing snow-melting nozzle 103 is buried, and then the handle 75 is used to change the screw rod 72 for landing leg,
After turning 73 and 74 to adjust the horizontal (tilt) direction of the base 71, loosen the detent screw 80 and saddle 81
Operation to move the rotator, loosen the rotation stop screw 82, and turntable 83
The operation of turning the screw, the operation of re-tightening the rotation stop screw 82, the operation of re-tightening the movement stop screw 80, the operation of adjusting the height of the electric drill main body 90 by the handle 85, and the like, and the center of the shank holder 92 and the existing snow removal nozzle. Align the center of 103 and put the shank holder 92 into the end mill 9 for ceiling wall cutting.
5, the bottom blade 9 of the ceiling wall cutting end mill 95
It is confirmed by lowering the electric drill main body 90 with the handle 85 whether or not 4 hits a predetermined portion of the existing snow-melting nozzle 103. If it does not hit accurately, the position of the saddle 81, the direction of the turntable 83, and the inclination and position of the base 71 are corrected, and thus the ceiling wall cutting end mill 95 is accurately positioned and then stopped. After confirming the tightening of the screw 80 and the rotation stop screw 82, the weight 101 is placed on the base 71 after this confirmation. Then, by operating the handle 85, the bottom blade 94 of the ceiling wall cutting end mill 95 is lightly applied to the upper surface of the ceiling wall 104 of the existing snow-melting nozzle 103, and the slide gauge 99 is moved up and down in this state. In addition, the zero point is adjusted to a reference point (not shown), and then the handle 85 is returned to attach the bottom blade 94 of the end mill 95 to the existing snow removal nozzle 10.
3 and the electric drill main body 90 is rotated in this separated state and the handle 85 is operated to lower the end mill 95, and the center of the top wall 104 of the existing snow-melting nozzle 103 is lowered. The part is cut into a circle with the old water spray holes 105 left. Whether or not the cutting has been sufficiently performed is confirmed by means of knowing that the depth of the cutting has reached a predetermined dimension by looking at the descending amount of the slide head 86 on the scale of the slide gauge 99 which has been adjusted to zero. Then, after stopping the electric drill body 90, the handle 8
Operate 5 to return to the upper position, and end mill for ceiling wall cutting 9
5 is removed from the shank holder 92, and the portion 106 surrounded by the circular cutting and the built-in object 107 such as the old valve are removed by a special plier. Further, a drill 96 for drilling a hole is attached to the shank holder 92, and the drill 96 for drilling a hole is rotated and lowered to remove the existing snow-melting nozzle 10.
