Concrete blocks for reinforced earth retaining walls and methods of joining them

Abstract

The invention provides a concrete block for a reinforced soil retaining wall and a connection method thereof. The concrete block comprises: a block body having an inner side facing the wall and an outer side facing away from the wall; a top of the block body There is a water collection tank set through the surface, and the inside of the block body is provided with a drainage hole connected with the water collection tank, and the drainage hole extends outward to the outer surface of the block body; along the height direction of the wall, two adjacent blocks The block body is adapted to butt up and down to form an accommodation space suitable for insertion of the longitudinal ribs of the drainage geogrid, and the accommodation space communicates with the water collection tank. The longitudinal rib of the drainage geogrid in the present invention is placed in the accommodation space, and the gravity of the concrete block will not be applied to the longitudinal rib of the drainage geogrid, so the outlet of the drainage geogrid longitudinal rib will not be deformed or blocked Phenomenon: the water body in the longitudinal rib of the drainage geogrid can smoothly overflow into the sump, and then be discharged through the drainage hole.

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...
