Abstract

PURPOSE:To eliminate vibration by cutting the established pavement layer at both sides of a groove for laying sprinkling block bodies in accordance with both the inclined side surfaces of the block bodies, filling sand, pebbles, or the like in the cut clearance, and then paving the cut part. CONSTITUTION:A water pipe 3 is buried inside a block body (a) which has an almost flat top surface 1 and inclining surfaces 2 being wider gradually toward the lower side, and plural sprinkling nozzles 4 are erected to the water pipe 3. Then, while the block body (a) is laid in a laying groove 9 at the level same as the upper surface of an established pavement layer 11, the layer 11 at both sides of the laying groove 9 is cut off the width almost same as the width of the clearance 12, and after the sand 13, the pebbles, or the like is filled in the clearance 12, a new pavement layer 14 is formed at the upper side of the block body (a) and at the cut part of the layer 11. And, the vibration when an automobile passes is eliminated by the block body (a) made up in the section of a trapezoid and the sand 13. The vibration can be eliminated, consequently.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a lightning extinguishing block for a road that is laid in the center of a road in a snowy area to make it a snow-clearing road, and a construction method thereof.

[Problems to be solved by conventional technology and invention]

The applicant developed a construction method for completing a snow removal road by providing a lightning extinguishing nozzle as a concrete block, joining these concrete blocks and attaching them to the road surface, and obtained Utility Model Registration No. 1556714 (1973- No. 13459)
is registered.

As a result of actual construction and testing of various performances and durability, it was confirmed that if the cross section of the block body is square as in the above-mentioned Utility Model Publication No. 55-13459, there are the following drawbacks. .

■The top width of the block body tends to be wide.

■The grooves carved into the road tend to be wide.

■Cracks tend to occur at the A part and the mouth part in Figure 5.

■The pavement layer in the second groove is likely to peel off.

In order to solve these problems, the inventor completed the present invention by repeatedly conducting various prototype tests.

[Means to solve the problem]

The details are as follows with reference to the attached drawings.

A water pipe 3 is buried inside an elongated block body a having a substantially flat top surface 1 and an inclined side surface 2 that becomes wider toward the bottom. 4° is exposed on the outer surface of the block body a and installed in a communicating state, and an O-ring receiving groove 5 is provided at one end of the water pipe 3 (3
A joint inner cylinder 6 is arranged in a row so as to protrude from the side surface of the block body a, and a joint outer cylinder 7 fitted into the protrusion 6° of the joint inner cylinder 6 is blocked on the opposite side of the water pipe 3. The plurality of block bodies a are connected in series by being arranged in a state substantially flush with the side surface of the body a, and by press-fitting the joint inner cylinder 6 into the joint outer cylinder 7 via the O-ring 8. This invention relates to a lightning extinguishing block for a lightning extinguishing road, which is characterized by forming a water sprinkler block body A of a desired length.

A water pipe 3 is buried inside an elongated block body a having a substantially flat top surface 1 and an inclined side surface 2 that becomes wider toward the bottom. 4" are exposed on the outer surface of the block body a and installed in a communicating state, and a joint inner cylinder 6 provided with an O-ring receiving groove 5 at one end of the water pipe 3 is installed in a continuous manner so as to protrude from the side surface of the block body a. ,
A joint outer cylinder 7 fitted into the protrusion 6' of the joint inner cylinder 6 is installed on the opposite side of the water pipe 3 so as to be substantially flush with the side surface of the block body a, and the joint inner cylinder 6 is A plurality of block bodies a are connected in series by press-fitting into the joint outer cylinder 7 via an O-ring 8 to form a water sprinkling block body A of a desired length, and this water sprinkling block body A is attached to the road surface 10. The block body a is laid in the carved laying groove 9 so that the upper surface of the block body a is substantially flush with the upper surface 11' of the existing pavement layer 11, and the existing pavement layer 11 on both sides of the laying groove 9 is laid on the inclined side surface 2 of the block body a. The width of the gap on both sides of the groove is cut out, and the gap in the laying groove 9 is filled with sand 13, gravel, etc., and a new pavement layer 14 is placed on the 1 side of the block body a'' and the cut out part of the existing pavement layer 11. The present invention relates to a method of constructing lightning extinguishing blocks for roads, which is characterized by providing lightning extinguishing blocks for roads.

[Effect]

When the joint inner cylinder 6 and the joint outer cylinder 7 are press-fitted, the water pipes 3 of the block bodies a are joined in an airtight state due to the presence of the O-ring 8.

When groundwater is sent to the water pipe 3 (for example, by operating a pump and sending water through the drain pipe 16), the groundwater is sprinkled onto the road through the nozzle hole 4'' of the watering nozzle 4, melting snow on the road. It will be Kazuko.

Even if the block body a vibrates due to vibrations when a car passes by, the cross section is trapezoidal and the gap 12 in the laying groove 9? Since the sand 13 is filled, vibration in the vertical direction is prevented compared to a case where the cross section is rectangular. For this reason, no cracks occur in the fourth part A in Figure 2.

Further, since the paving layer 14 is newly paved not only on the upper surface of the block body a but also over the cut portion of the existing paving layer 11, it becomes difficult to peel off.

The sand 13 in the laying groove 9 firmly presses down on the block body a by pouring water.

〔Example〕

It is desirable that the inclined side surface 2 of the block body a be made into a rough surface with unevenness to improve the adhesion with the pavement layer 14.

U7 The top surface of the vine body a may be colored to form a road marking strip on the top surface of the watering block body.

〔Effect of the invention〕

The present invention provides an excellent lightning extinguishing block for roads and its construction method, which has the following features.

(1) Since the cross-sectional shape of the block body a is made into a trapezoid type, the top surface becomes narrower by 11 mm, so it looks good when attached to the center of the road, and the top surface of the block body a forms the central strip as it is. Moreover, the fact that the exposed area of the block body a is 11 times smaller means that it is less likely to be stepped on by an automobile and vibrated, making it much more practical than the conventional block body a having a rectangular cross section.

(2) Since the cross-sectional shape of the block body a is a trapezoidal type, when it is laid in the laying trench, the gaps on both sides will be about 11゜wide, so if you fill this gap with sand or gravel, etc. Vibrations caused by the frequent passing of automobiles are reliably suppressed, and there is no slight movement, especially in the vertical direction, which prevents cracks from forming at the mouth part (a) in Figure 2, and prevents the paving of the trench from peeling off. blocked.

(3) Replace the new pavement layer with IJ on both sides of the groove (11), making it easier to apply compaction rollers.1-7-
This will ensure that delamination is prevented.
