Block for constructing reinforced earth wall

Abstract

A block for the construction of a reinforced soil segmental retaining wall. The block includes a front surface, a rear surface, left and right lateral surfaces, an upper surface having a pair of left and right reinforcement insertion grooves, and a lower surface opposite to the upper surface. A pair of anchor pin insertion bores are vertically perforated at left and right sides of the upper and lower surfaces so that anchor pins are inserted therethrough to connect vertically neighboring blocks. Also, a pair of through-passages are vertically perforated from the upper surface to the lower surface to be laterally spaced apart from each other by interposing a partition.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] Applicant claims priority under 35 U.S.C. §119 from Korean Application No. 10-2005-0059542 filed on Jul. 4, 2005 and Korean Application No. 10-2005-0084510 filed on Sep. 12, 2005. BACKGROUND OF THE INVENTION [0002] The present invention relates to a block for use in the construction of a reinforced-soil segmental retaining wall, which has a plurality of advantages. First, the block enables convenient construction of the segmental retaining wall by the use of equipment instead of a conventional ineffective labor-intensive manner. Second, the block has no shear cracks even when it confronts uneven subsidence of ground. Third, the block allows a leading end of a reinforcement to be directly connected thereto without using a separate anchor. Fourth, a mono-layer, dual-layer, or multiple-layer blocks can be evenly stacked one upon the other and side-by-side in a staggered-stacking manner or in a vertically-aligned stacking manner to achieve ...

AI Technical Summary

Benefits of technology

[0007] Therefore, the present invention has been made in view of the above problems, and it is a first object of the present invention to provide a block for use in the construction of a reinforced-soil segmental retaining wall, which enables convenient and rapid construction of the segmental retaining wall by the use of equipment without causing various problems made by manual operations.

[0008] It is a second object of the present invention to provide a block for use in the construction of a reinforced-soil segmental retaining wall, which can prevent the sliding of blocks upon uneven subsidence of ground, thereby preventing the generation of shear cracks and damage to L-shaped angled portions.

[0009] It is a third object of the present invention to provide a block for use in the construction of a reinforced-soil segmental retaining wall, which can allow a leading end of a reinforcement to be directly connected to the block without using a separate anchor, thereby enabling the simplified connection between the reinforcement and the retaining wall and preventing the leading end of the reinforcement from relaxing and being exposed to the outside.

Problems solved by technology

First, the block enables convenient construction of the segmental retaining wall by the use of equipment instead of a conventional ineffective labor-intensive manner.

However, the known conventional technologies have the following several problems.

This is a labor intensive undertaking that also results in ineffective slow construction of the retaining wall.

Moreover, when it is desired to construct the retaining wall within a short time, it requires an extensive mobilization of manpower, resulting in an excessive increase in labor costs and other various problems.

Problems of a conventional panel-type reinforced-soil segmental retaining wall are that the retaining wall does not allow the growth of plants thereat and is less aesthetic as compared to the block-type retaining wall, although the panel-type retaining wall can be constructed much more quickly by the use of equipment with low labor requirements.

Thus, the panel-type retaining wall lacks harmony with the natural environment.
