Concrete block for reinforced earth retaining wall and connecting method thereof

Abstract

The invention provides a concrete block for a reinforced earth retaining wall and a connecting method thereof, and the concrete block comprises a block body which is provided with an inner side surface facing a wall body and an outer side surface deviating from the wall body; a water collecting groove is formed in the top surface of the building block body in a penetrating manner, and a drainage hole communicated with the water collecting groove is formed in the building block body and extends outwards to the outer side surface of the building block body; in the height direction of the wall body, every two adjacent building block bodies are suitable for being in butt joint up and down so as to form a containing space suitable for being inserted by a drainage geogrid longitudinal rib, and the containing space is communicated with the water collecting groove. The drainage geogrid longitudinal ribs are arranged in the containing space, the gravity of the concrete blocks cannot be applied to the drainage geogrid longitudinal ribs, and therefore the drainage openings of the drainage geogrid longitudinal ribs cannot deform or be blocked; water in the longitudinal ribs of the drainage geogrid can smoothly overflow into the water collecting tank and then is drained through the drainage holes.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a concrete block used for a reinforced soil retaining wall and a connection method thereof. Background technique [0002] For the construction of reinforced earth retaining walls, gravel soil with good water permeability and high strength is mostly used as filler; but in many practical projects, it is difficult to find suitable gravel soil due to the limitation of construction conditions, or because the transportation cost is too high , making the cost uneconomical. Therefore, the use of clay as filler has entered the scope of consideration of engineers. Many scholars at home and abroad have also conducted a lot of research on the deformation characteristics and stability of reinforced clay retaining walls. Using drainage geogrids as reinforcement materials has successfully A reinforced clay retaining wall was constructed and has been monitored over a long perio...
