Abstract: In the invention, a sludge treatment technology adopting flocculation-horizontal drain board vacuum preloading combining multi-layer sealed geotextile bag is disclosed, which comprises sealed geotextile bags and a geomembrane for sludge grouting and filling. The sealed geotextile bag and the geomembrane have two splicing modes, one is to place a layer of geomembrane inside and close to the inner side of the sealed geomembrane; the other is to wrap and seal the outside of the geotextile with geomembrane. A horizontal drainage system for vacuum drainage is set inside the sealed geotextile bag, with one end of the horizontal drain board being connected to a vacuum drainage pipe, and the drainage pipe passes through the sealed geotextile bag via a flange and is connected to the vacuum pump used for pumping the water in the sealed geotextile bag. Sludge includes engineering waste mud, river sludge and industrial sludge.

Abstract: The disclosure provides an optical imaging lens assembly, which sequentially includes from an object side to an image side along an optical axis: a first lens with a positive refractive power, an object-side surface thereof is a convex surface, and an image-side surface thereof is a concave surface; a second lens with a negative refractive power; a third lens with a refractive power; a fourth lens with a refractive power; a fifth lens with a positive refractive power; a sixth lens with a refractive power; a seventh lens with a positive refractive power; and an eighth lens with a negative refractive power. ImgH is a half of a diagonal length of an effective pixel region on an imaging surface of the optical imaging lens assembly, ImgH, an entrance pupil diameter (EPD) and a total effective focal length f of the optical imaging lens assembly satisfy: 4.3 mm<ImgH×EPD/f<5.3 mm.

Abstract: A method for foundation consolidation combining vacuum preloading and geomembrane bag assembly loading, which comprises: digging a slurry pit, filling mud into the slurry pit and conducting vacuum preloading pumpdrainage for multiple times, laying the geomembrane bag assemblies above the soft slurry seam processed through vacuum preloading pumpdrainage inside the slurry pit to form a plurality of loading layers, and laying the geomembrane bag assemblies by piling geomembrane bags. In view of the engineering complexity and uneven settlement resulting from conventional vacuum preloading using slag loading, geomembrane bag for loading to overcome the adverse effects of slag loading. In the present invention, the drainage system and the geomembrane bag assemblies are laid out to fully leverage their perspective properties, so as to improve the transmission of vacuity in the whole soil mass, speed up the drainage rate, and increase the degree of consolidation.

Abstract: A nanowire field effect junction diode constructed on an insulating transparent substrate that allows form(s) of radiation such as visual light, ultraviolet radiation; or infrared radiation to pass. A nanowire is disposed on the insulating transparent substrate. An anode is connected to a first end of the nanowire and a cathode is connected to the second end of the nanowire. An oxide layer covers the nanowire. A first conducting gate is disposed on top of the oxide layer adjacent with a non-zero separation to the anode. A second conducting gate is disposed on top of the oxide layer adjacent with a non-zero separation to the cathode and adjacent with a non-zero separation the first conducting gate. A controllable PN junction may be dynamically formed along the nanowire channel by applying opposite gate voltages. Radiation striking the nanowire through the substrate creates a current the anode and cathode.
