Description

Concrete Road Block and System using it

The present invention relates to a concrete road block and a road block system using the same, and in more detail, it includes an upper plate, a lower plate and an elastic plate so that it can be installed and operated directly at road construction construction sites such as intersections and bus lanes. A concrete road block that is composed of a module and can be manufactured in advance (Pre-Cast Type), and a road block that can flexibly respond to the condition of roads and ground layers having various widths, lengths, and widths using the same. It is an invention of the system.

Roads (lanes) pavement work such as intersections and bus lanes include restoration work after excavation due to the construction of new roads, repairs, and burial of water and sewerage.The paving material for such paving works is asphalt concrete (ascon). Asphalt pavement construction and readymix concrete (concrete pavement using ready-mixed concrete) construction are representative.

With this construction method, road construction, repair, and excavation restoration and pavement work are carried out, but in the case of asphalt concrete pavement work, the construction cost budget increases due to the input of many heavy equipment such as asphalt finisher and various rollers. In order to restore the excavated pavement after the excavation work, in order to perform the asphalt concrete pavement work, the surface asphalt concrete must be installed after the base asphalt concrete is installed. There are many. In this case, it has been pointed out that if ascon for the base layer and ascon for the surface layer are urgently installed, there may be a case of reconstruction due to inadequate compaction work and economic damage.

In order to prevent this, the current construction method is to complete the construction by passing the vehicle after laying the base asphalt concrete and installing the surface asphalt concrete after securing the amount of construction for a certain section.

However, not only increases construction cost due to frequent base ascon laying, which is less than daily pavement productivity, and when the pavement construction is replaced with non-woven fabrics and safety fence facilities on the road pavement excavation recovery surface, the damage increases due to scattering dust and vehicle congestion at the construction site. It has also been pointed out.

In order to solve this problem, ideas in the form of an assembly type block made of concrete have recently been proposed as in the patent documents cited below. However, in order to solve the vibration reduction caused by the movement or stopping of large vehicles such as buses, There has been still a need for solutions to problems such as improvement of workability and stability of concrete road blocks for a certain period after construction.
