Description

ECO-FRIENDLY BLOCK STRUCTURE FOR EXPANDING ROAD AND THE CONSTRUCTION METHOD THEREOF}

The present invention relates to a road and sidewalk expandable block structure, and more particularly, in the road and sidewalk expansion block structure for extending the road and sidewalk by installing a plurality of block structures along the road and sidewalk in succession to each other. The bottom plate and the connecting part are integrated with each other to form a 'Z' shaped block structure, which minimizes the assembly process in the field and simplifies the process so that the construction period can be shortened. Furthermore, the durability and the quality of the product are improved. The present invention relates to an environmentally friendly road and sidewalk expandable block structure and its construction method, which are made to be kept constant and that the structure is stable even after installation in the field so as to cope with floating settling or shearing force.

As living standards improve in recent years, more and more people are interested in outdoor activities such as walking, cycling and inline skating, and driving a car. These outdoor activities are mainly performed in rivers, streams, or mountainous areas. Conventional roads installed in these areas are built long time ago in accordance with the natural environment of the area and are very narrow. People are always at risk of serious and fatal safety accidents.

Therefore, the necessity of solving the problems of the existing narrow roads installed in these areas is increasing. It is not only economically overwhelming to reconstruct existing civil structures for wider roads for the safety of passengers. In case of expanding the sidewalk or bicycle road in Josie, the area occupied by civil engineering structures becomes too large. Therefore, in case of bridges, the construction cost is too high. In the case of mountainous regions, the basic construction must be carried out separately to secure sufficient road width. There is a problem.

In order to solve these problems, according to the prior art, various road extension block structures and construction methods have been proposed, but the construction period can be shortened by minimizing the assembly process in the field and simplifying the process, and the quality of the product is improved. The road extension block structure and its construction method to maintain a constant, excellent durability, and to stabilize the structure even after installation on the ground to cope with floating load or external load have not been developed yet.

Republic of Korea Utility Model Registration No. 20-0348534 (registered on Dec. 12, 2006) discloses a winged sidewalk block. As shown in FIG. 1, the conventional wing-type walkway block relates to a wing-type walkway block protruding out of a road at a place such as a bridge or a waterway, and includes a base portion having a flat plate shape embedded with soil and gravel at the bottom ( 5) and a block support 2 having an L-shaped cross section formed of concrete to have a side wall 6 formed upright with a plurality of through holes 8 upright on one side of the base portion 5; ; An inverted L-shaped top plate support having a horizontal bar extending outwardly and an upright portion provided with a plurality of anchor bolts 7 fixed to the side wall by nuts 9 through the through holes 8. 3) and; It is characterized in that it comprises a flat-shaped walkway top plate 4 which is fixed to the horizontal bar 3a of the top plate support 3 and is molded of prestressed concrete so that a handrail is installed outside.

However, the conventional technology as described above has a problem in that the construction period is increased because the complex assembly process in the field is necessarily accompanied by the assembly type, durability and quality may vary depending on the conditions of the site and the skill of the technician. Furthermore, there are still problems such as defects or subsequent maintenance due to assembly on site.

The present invention was made to solve the problems of the conventional road expansion block structure and its construction method as described above, to continuously install a plurality of block structures along the road and sidewalk to extend the road and sidewalk In the block structure for road and sidewalk extension, the block structure has an upper surface exposed to the ground surface, and a plurality of first through-holes are formed on left and right sides for joining the formwork for curved road parts. An upper plate portion formed at an end thereof with a drainage ditches and a through drainage hole for drainage of rainwater and having a predetermined gradient toward the through drainage hole; A bottom portion having a plurality of fixing through holes through which bolts for fixing the block structure to the foundation concrete are formed so that the block structure is settled in the ground; and from the bottom portion at the other free end side of the bottom portion, A bottom plate portion including a protrusion 220 having a structure projecting in a direction; An eco-friendly road and sidewalk expandable block structure comprising an upper part and a lower part integrally connected in an oblique direction and comprising a connection part formed with a plurality of second through-holes for coupling a formwork for curved road parts. By providing a block structure formed integrally, there is no need for a separate assembly process, so that the process is simple and the construction period can be shortened, and defects or subsequent maintenance that can occur during the assembly process can be eliminated. The purpose.

In addition, the present invention is a method for constructing a road and sidewalk extended block structure along the curved portion of the road, the curved portion construction method is provided with a plurality of block structures continuously along the curved portion of the road, the first through hole formed in the upper plate And a plurality of block structures by using a first die having through holes formed at a position corresponding to the second through hole formed at the connecting portion and a second die having through holes formed at a position corresponding to the second through hole formed at the connecting portion. Providing a road and sidewalk extended block structure construction method characterized by placing concrete in the empty space between the block structures formed by being installed in the curved portion of the road, the construction period by simplifying assembling at the curved portion of the road Can be shortened, durable and product quality is consistent And to ensure that if for that purpose.

In order to achieve the above object and to solve the above-mentioned problems of the prior art, the road and sidewalk extension block structure according to the preferred embodiment of the present invention, the upper surface is exposed to the ground surface and a plurality of first through holes ( hole) and an upper plate portion in which a drainage trench and a through drain are formed; A bottom plate portion including a bottom portion having a plurality of fixing through holes formed therein, and a protrusion having a structure projecting upwardly from the bottom portion; The top plate and the bottom plate is integrally connected in an oblique direction, and a plurality of second through holes are formed, and the top plate, the bottom plate, and the connecting portion are integrally formed with each other to form a 'Z' shaped block structure. And a plurality of block structures along the road and sidewalk is characterized in that are installed in succession with each other.
