Methd for building retaining wall and retaining block therefor

Abstract

The method for building retaining wall includes the following steps: in the position having need of building wall body laying the foundation, then piling up retaining blocks, at the same time backfilling soil into inner side of retaining wall to form backfilling soil body, setting a layer of water-filtering aggregate between the backfilling soil body and retaining wall, and setting binding net sheet in the different height positions of backfilling soil body and retaining wall respectively. The described retaining block is characterized by that its one side has a projection, and another side has a recessed groove.

Description

technical field [0001] The invention relates to a method for building a retaining wall and a retaining block used in the method, belonging to the construction field. Background technique [0002] At present, bricks, block stones, plain concrete, reinforced concrete and other materials are required to build walls. This method leads to a large amount of construction materials, labor and maintenance costs for walls, and the retaining soil constructed by these materials The wall is not suitable for the subsidence of the foundation, impermeable, the wall is easy to break, and the backfill soil or the retained soil is easy to form a seepage channel, so it is necessary to set up drainage holes in the lower part of the wall, and since the drainage holes are located near the foundation of the wall, it will It affects the stability of the foundation of the retaining wall, causes water and soil erosion, and also affects the ecological environment, the atmosphere and the water environme...

[0002] At present, bricks, block stones, plain concrete, reinforced concrete and other materials are needed to build walls. This method leads to a large amount of construction materials, labor and maintenance costs for walls, and the retaining soil constructed by these materials The wall is not suitable for the subsidence of the foundation, impermeable, the wall is easy to break, and the seepage channel is easy to be formed in the backfill soil or the retained soil, so it is necessary to set up drainage holes in the lower part of the wall, and since the drainage holes are located near the foundation of the wall, it will It affects the stability of the foundation of the retaining wall, causes water and soil erosion, and also affects the ecological environment, the atmosphere and the water environment, pollutes the environment, and its construction and maintenance costs are also high
