Different residual thickness of the surface regolith, the use of low concentration (less than 5%), multiple penetration, penetration in the windward side of the number three times in the leeward side for 4 to 5 times. Permeability layers in the 20 ~ 30 min after inspection, PS asked to ensure the construction quality. I would like to concentrate on the issue whether these ornaments of the bronze weapons have any meaning. A wall after wall before it is processed in LMH dig eclipse parts of the reinforcement processing: basic dig eclipse recessed wall formation vacant surface, thereby causing the wall collapsed, the traditional method is the use of adobe masonry support top reinforcement. This approach adobe ruins of soil similar to Preparation of silt, salt content ≤ 0.50%, the moisture content of ≤ 3.0%, dry density ≥ 1.70 g/cm3; masonry mud clay, the modulus of 3.8, a concentration of 5% PS solution mixing, water-cement ratio of 0.4.
Masonry adobe First remove loose regolith surface of the touch surface, the spray concentration of 3 to 5 percent PS solution, processed in a timely manner masonry adobe; adobe masonry walls are closely integrated; and PS-C (PS and clay) slurry grouting, ensure that the masonry and the wall to form a unified whole, plus the wood in the masonry bolt, to prevent the the slurry contraction of the masonry wall from the adobe masonry is completed, spray the right amount of water to make mud-brick surface to soften, a little bit and work the old in order to achieve a similar effect of appearance with the original soil; adobe masonry is completely dry , and then spray concentration of 3 to 5% PS solution to infiltrate the reinforcement. Whether figurine bronze are related to mythological and religious tradition is not sure yet.
Adobe masonry construction on the face during take protective measures and the increase of solid slowly dried to avoid the formation of cracks. By its stern and angular appearance, the design seen on ancient bronze musical instruments of China strikes the viewer. The above method to solve the shortcomings of the traditional craft of masonry and wall re-separation caused by the reinforcement of failure for the old treatment, changed the traditional process to affect a greater disadvantage to the bronze art appearance. cliff reinforcement treatment: fractured PS. F grouting at the same time secondary to anchor reinforcement. In geotechnical engineering design of the anchor is more mature, but mainly a steel bolt and steel noose, the reinforcement of the steel material in the soil sites, it's defective, less durable materials, grout material commonly used in cement.
It is not suitable for the reinforcement of the soil sites, the strength of the grout soil sites requires slightly larger than the strength of the soil, can not exceed too much, otherwise easily lead to the destruction in the reinforcement of the soil sites requires deformation of the bolt to be smaller, therefore, be Select the new anchor materials. As Bagley pointed out, “ancient Chinese nude statues have an exotic and mysterious character, at least in the eyes of modern observers.” Choice of anchor, according to the actual survey, soil sites in the northwest, save a large number of wooden structures, the service life of over two thousand years, can still play a good role, therefore, consider using bamboo bolt reinforcement .
Anchor of the Φ35mm the bamboo wood, the moisture content of ≤ 3.0%, single anchor rod tensile strength should be greater than 10.0KN; anchor hole threaded drill artificial drilling, pore size of about 42 rain, the hole depth should be higher than, clear the hole in the virtual earth bolt design length of 100 mm; hole drilled into the mold of 3.8, the concentration of 5% PS solution reinforcement hole wall; hole wall after curing, the injection of Ps-c serous, serous modulus of 3.8, the concentration of 10% PS and clay, preparation of water-cement ratio of 1:1.3 ~ 1.5; injected into the slurry should then insert the bolt, to ensure that the anchoring force of the rod with the hole wall. The most stunning element is the pair of animal eyes projecting from the surface of the bronze sculpture wildlife and staring at the viewer with a bewitching force.
