Technical Field

The invention relates to the field of roadbed slope protection, in particular to a tenon-and-mortise prefabricated high-strength interlocking block arched slope protection.

Background

the arch skeleton bank protection is a common engineering protection scheme in the protection of roadbed side slopes, and the existing highway and local road network project embankment fill height is more than 4 meters side slopes, and is generally used. The framework material is commonly made of grouted rubbles, and cast-in-place concrete and precast concrete are also adopted in areas lacking stone materials.

With the increase of labor cost, the economic advantages of mortar rubble and cast-in-place concrete arch protection are not outstanding, the construction field engineering quality is not easy to control, the whole appearance of the masonry is slightly poor, and diseases such as less mortar, no mortar, cavities, whole collapse and the like are easy to occur. Therefore, the construction side is more inclined to prefabricate the concrete arch-shaped revetment so as to realize standardized design and industrialized production.

The conventional precast concrete arch-shaped revetment mainly has the following two problems:

1. And the connection measures are lacked among the precast blocks, so that the integral instability and collapse are easily caused.

2. the precast block generally adopts low strength concrete, and can only adopt the increase thickness to guarantee self intensity, and then causes the vicious circle that thickness is big, from great, installation inconvenience.
