Block for constructing retaining wall, prefabricated reinforced retaining wall constructed using the block and construction method of the prefabricated reinforced retaining wall

Abstract

Provided are blocks for constructing a retaining wall, a prefabricated reinforced earth retaining wall constructed using the blocks, a method for constructing the prefabricated reinforced earth retaining wall. The block for constructing a retaining wall comprises a front surface 10 forming a surface of the retaining wall, and a rear surface 20; left and rights sides 30 and 30' having corresponding intermeshing portions 32 and 32' formed thereon; a top surface 40 having reinforcement member insertion grooves 44 formed in a front-to-rear direction, and fixture grooves 46 formed on either side of the front of the reinforcement member insertion grooves 44 for fixing the reinforcement member or anchor; and a bottom surface 50 corresponding to the top surface 40, wherein a connecting pin insertion hole h1 for pinning upper and lower blocks with a connecting pin and a lifting pin insertion hole h2 for simultaneously lifting the upper and blocks, penetrate through the top and bottom surfaces 40 and 50.

Description

technical field [0001] The present invention relates to blocks for constructing retaining walls, prefabricated reinforced earth retaining walls constructed using blocks, methods of constructing prefabricated reinforced earth retaining walls, and methods of repairing retaining walls. The present invention intends to reduce transportation and material costs by making the front wall of the retaining wall light in weight, while having excellent workability during construction by using equipment that minimizes field labor. Another advantage of the invention includes high durability against possible permanent subsidence after construction of the geotechnical structure, and easier repair in case of partial failure of the retaining wall. Background technique [0002] The prefabricated reinforced soil retaining wall which is the field of the present invention has the following advantages over the conventional concrete retaining wall: the retaining wall can be constructed vertically a...

Problems solved by technology

First, the single shape and appearance of traditional paneled reinforced earth retaining walls are not attractive

From the viewpoint of environmental friendliness, the traditional retaining wall is not in harmony with the surrounding environment, and it appears bare because it does not allow plants to grow

In addition, even when the lower retaining wall is slightly damaged, usually, in order to replace the damaged panel board with a new one, a large amount of dismantling work must be done to the overlying panel and adjacent panels.

As such, repairing a conventional retaining wall is expensive, labor intensive and even more difficult than building a new retaining wall and requires extensive equipment

[0005] The problem with the traditional prefabricated block reinforced soil retaining wall is that the blocks are alternately staggered. After the construction is completed, if the load from the upper part of the retaining wall acts as a shear force, the overlapping part of the block below is easily sheared off.

Compared with the case of panel type reinforced earth retaining wall, repair work is difficult

Because in order to prevent overturning and locate the locking part, the length of the block of the traditional reinforced earth retaining wall is much larger from the front to the rear than the width from the left to the right, and a single block has a heavy load, thus consuming a lot of construction materials

This heavy load also makes it difficult to construct retaining walls, causing inconvenience in work

In addition, due to the difficulty in using equipment to construct, the construction period was extended
