Abstract: A method for reinforcing soft ground by post-grouting combined with pressurized vacuum preloading is proposed, by pre-burying prefabricated vertical drains and air-boosted pipes in granular material piles, and the air-boosted pipes are used as grouting pipes to reduce the number of times of piling, which not only improves the construction efficiency, but also reduces the structural disturbance of the soil and the influence of smear effect, thus reducing the impact on the radial permeability and the radial consolidation coefficients. The method does not use geotextile bags for granular materials, which can avoid the problem of forming a localized clogging area around the geotextile bags, and the method not only improves the efficiency of vacuum transfer in a pre-consolidation stage, but also improves the grouting effect in the later stage, effectively enhances the strength of soft soil and makes granular material piles and the surrounding soil form composite ground.

Abstract: The invention provides a method for preparing a key intermediate for the synthesis of (S)-2-(3S,8S)-3-(4-(3,4-dichlorobenzyloxy)phenyl-7-((S)-1-phenylpropyl)-2,3,6,7,8,9-hexahydro-[1,4]-dioxino[2,3-g]isoquinolin-8-ylformylamino)-3-(4-(2,3-dimethylpyridin-4-yl)phenyl)propionic acid dihydrochloride: methyl (S)-2-amino-3-(4-(2,3-dimethylpyridin-4-yl)phenylpropionate and the salt thereof. The method adopts continuous feeding mode, does not require column chromatographic purification, simplifies the procedures, reduces loss and increases yield. Furthermore, the product, i.e., salt of methyl (S)-2-amino-3-(4-(2,3-dimethylpyridin-4-yl)phenylpropionate, obtained by the purification mode of salt formation, has high purity and good storage stability. The preparation method of the invention can achieve a total yield of above 85%, a purity of the target product of above 98%, and a content of the isomer of below 0.5%.
