Mud-water amphibious plate-inserting device for soft foundation

The invention discloses a mud-water amphibious plate-inserting device for a soft foundation, which comprises a plate-inserting machine, wherein the plate-inserting machine is arranged on a track, and the track is arranged on a floating body; and the plate-inserting machine comprises a bracket, a plastic drain board conveying device, an inserting tube and a bidirectional driving device thereof. By using the mud-water amphibious plate-inserting device to carry out soft foundation treatment, the invention cancels the phase of paving geotextiles and wattles or the phase of temporarily consolidating the superficial layer of a manually-inserted drain board in the traditional process, and omits a fine sand bedding layer and a coarse sand filtering layer, thereby saving the temporary consolidation treatment phase in the treatment procedure and saving a great quantity of nonrenewable resources and a lot of money; after mud is subjected to hydraulic reclamation, the plate inserting operation can be performed under the condition that water is adhered to the mud, thereby greatly shortening the construction period; and meanwhile, because the plate-inserting depth can reach more than 20 meters, plates can be inserted in place in one-step operation. Thus, a lot of money can be saved by only omitting the fine sand bedding layer and the coarse sand filtering layer; and compared with the traditional process, the construction time is greatly shortened.

Physicochemical-biological combined treating method for high-concentration organic pyrosulfite wastewater

The invention discloses a physicochemical-biological combined treating method for high-concentration organic pyrosulfite wastewater. The method comprises the following six steps: 1) Fenton oxidation; 2) neutralization with quicklime; 3) inclined-plate precipitation; 4) chemical flocculation; 5) filtering with quartz sand; and 6) biologically reinforced treatment with pyrosulfite-tolerant engineering bacteria. According to the invention, weak acidity of the organic pyrosulfite wastewater is made full use of, the strong oxidation effect of a Fenton reagent under the condition of weak acidity is given to play so as to oxidize pyrosulfite with toxicity into nontoxic sulfate, and macro-molecular organic matters in the wastewater can be degraded small molecules, so biodegradability of the wastewater is improved; and the domesticated engineering bacteria with salinity tolerance of 50 g / L are used as bacteria in a biologically reinforced treatment phase for three-stage biologically reinforced treatment so as to microfloras adaptive to environment, so degradation of the wastewater is efficiently realized under cooperation of the microfloras and effluent totally meets primary standards prescribed in Comprehensive Wastewater Discharge Standard in China.

Reconfigurable dental model system for fabrication of dental appliances

InactiveUS20080206701A1Impression capsOthrodonticsEntire dentitionIntermediate stage
The present invention provides a manipulable or reconfigurable dental model system and methods for its use to model a series of tooth configurations corresponding to sequential tooth movements during an orthodontic treatment. When a patient undergoes orthodontic treatment, teeth and bite configurations are realigned in a series of stages. Each stage represents a new pattern or dental configuration that will eventually lead to a proper final positioning of the entire dentition. Progress from the initial configuration, through the intermediate stages and finally to the final configuration may be accomplished using any one or a combination of different dental appliances. Of particular interest to the present invention, many of these appliances may be made using a dental mold representing the patient's dental configuration. In particular, thermoformable plastic positioning appliances which fit over the patient's teeth may be formed over a three-dimensional mold of the patient's dentition. When successive appliances are used throughout treatment to reposition the teeth from initial to final configuration, a new mold has typically been produced to fabricate the appliance for each stage. The present invention provides an apparatus and methods which employ a manipulable or reconfigurable mold to model patient dentition and gingiva at each stage of treatment.
