Description
Technical Field

background
In arid and semiarid regions in northwest of China, a large number of earthen sites are left as one of important types of cultural heritages of China, and the earthen sites have extremely high historical, scientific, artistic and social values. However, due to the limitation of the construction process at that time and the influence of natural and artificial damage for a long time, a series of diseases which endanger the mechanical stability, such as sheet stripping, cracks, collapse, undercutting and the like, are generated on the earthen site body, and the safety occurrence of the earthen site is seriously influenced.
at present, aiming at the problem of sheet stripping of earthen sites, a reinforcement process of spray penetration and drilling dripping penetration is mainly adopted for repair treatment. Because the flake peeling has the characteristic of a binary structure, in the conventional spraying and penetrating process, the penetration depth of the reinforcing solution is limited, and the reinforcing solution cannot effectively penetrate through the shell layer and the powder layer to enter the rammed earth layer in the non-weathered area, so that after the conventional spraying and penetrating treatment is adopted, an incompatible phenomenon of 'two skins' exists between the flake peeling layer and the interface between the powder layer and the non-weathered area, and the peeling speed can be further increased. When the conventional drilling and dripping process is adopted, although the reinforcing liquid can be led to a deeper area and reach an un-weathered area by means of drilling, the permeation range of the reinforcing liquid is only in the peripheral area taking the drilling as the center, so that a large number of drilling holes need to be formed in the surface of the earthen site in order to increase the permeation coverage range of the reinforcing liquid, and the stability of the earthen site is influenced due to large disturbance generated on the earthen site. In addition, no matter spraying infiltration or drilling dripping infiltration, the infiltration is completed by depending on the complete free diffusion of the reinforcing liquid in the earthen site, so that the infiltration rate is low, the reinforcing efficiency is low, the range of an infiltration area is uncontrollable, and the infiltration reinforcing effect is unstable.
