As a preferable aspect of the present invention, the first notch and the second notch are both generally arranged along the side surface.
As the utility model discloses a preferred scheme, every still be equipped with the vegetation board on the prefabricated section, can afforest, the vegetation board also can directly carry out prefabricated production in the mill.
As the preferred scheme of the utility model, every the prefabricated section is solid construction.
As the utility model discloses a preferred scheme, every the prefabricated section is hollow structure, and hollow portion packs has the filler. The hollow structure can reduce the dead weight of the structure, save the consumption of concrete and facilitate transportation and assembly.
As the preferred scheme of the utility model, the filler comprises plain soil, broken stones and pebbles, and the waste slag on the available site is backfilled.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
retaining wall assemble through a plurality of prefabricated section and form, all the prefabricated section all can be in the prefabricated production of mill, can realize the full prefabrication of component, need not the maintenance, reduced the on-the-spot operation time, and improved construction precision and efficiency of construction. After the prefabricated section transports the scene, only need carry out transverse connection through the forked tail tenon of dovetail and adaptation, carry out vertical connection through grout sleeve can, the process is simple, the assembly of being convenient for. The utility model discloses in every the prefabricated section is the independent structure, connects through independent connecting piece between two adjacent prefabricated sections, in whole retaining wall structure, in case one of them connecting piece is impaired, only can influence rather than two adjacent prefabricated sections, can not influence the structural connection performance of other prefabricated sections, has avoided the production of chain effect.
And adopt grout sleeve to carry out wet joint connection, utilize reinforcing bar and grouting material ductility can effectively solve the stress concentration problem, reduce brittle failure, and further, adopt grout sleeve to connect, still can improve the anti-seismic performance of structure.
And self-locking is carried out by matching the dovetail groove with the dovetail tenon structure, the structure is simple, the applicability is good, and the stress requirement of transverse connection of the retaining wall can be met.
