The invention relates to the technical field of packaging, in particular to a material supplying mechanism. The material supplying mechanism comprises a second transferring unit, wherein the second transferring unit comprises a temporary material storing platform used for temporarily storing materials, and placement boards are arranged on at least one side of the temporary material storing platform; a scraping board capable of pushing the materials out of an upper platform surface and making the materials fall onto the placement boards is arranged on the upper platform surface of the temporarymaterial storing platform; the placement boards can do transverse opening and closing actions to form blanking openings for facilitating blanking, material buffering bins with a receiving function and upward bin openings are arranged under the blanking openings, and bin cavities of the material buffering bins and lower board surfaces of the placement boards match each other to together form accommodating cavities for accommodating the materials; and both ends of each material buffering bin are provided with openings, a first pushing unit which acts on the heads of the materials to jack the materials out of the material buffering bins is arranged in one opening of each material buffering bin, and a corresponding discharging opening of each material buffering bin is formed by the other opening of of each material buffering bin. By means of the structure, a structural support can be provided for orderly entrances of the materials to the next working procedure.

The invention discloses a prefabricated assembly well wall structure and a construction method thereof. The prefabricated assembly well wall structure is formed by splicing and assembling a plurality of prefabricated pipe pieces in the longitudinal direction and the annular direction; a plurality of prestress through holes penetrating through the upper end and the lower end, a plurality of grouting holes and a plurality of slurry discharging holes are formed in each prefabricated pipe piece at intervals; a prestress connecting element is arranged in each prestress through hole, and extends out from the upper end and the lower end of the corresponding prestress through hole; inclined inner holes are formed in two ends of the annular direction of the inner side of each prefabricated pipe piece; an inclined connecting sleeve is embedded in each inclined inner hole; and a force transmission bushing and a water stop structure are arranged between two prefabricated pipe pieces which are adjacent in the longitudinal direction and the annular direction. The prefabricated assembly well wall structure is formed by splicing the prefabricated pipe pieces; the vertical shaft foundation pit excavation enclosure exposure time is reduced; the complicated process of a wet construction work procedure is simplified; the work intensity of workers is reduced; the construction speed is high; the cost and the manufacturing price are low; the environment pollution is low; and good social effects and economic effects are achieved.

The invention discloses an uplift suction bucket foundation and an installation method thereof. The suction bucket foundation comprises a suction bucket; and a dead weight sinking system, a water flush sinking system, a reinforcing system and a plurality of layers of annular inclined grooves are further arranged on the periphery of the suction bucket. The method comprises the following steps that1, the dead weight of the suction bucket is increased; 2, the suction bucket sinks due to the dead weight; 3, the suction bucket sinks due to a water flush; 4, the suction bucket is reinforced; and 5,the dead weight of the suction bucket is increased again. According to the uplift suction bucket foundation and the installation method thereof, the annular inclined grooves are additionally formed,water conveying pipes penetrating through the annular inclined grooves are additionally arranged, gravel is placed in the annular inclined grooves so that the dead weight can be increased, the dead weight sinking depth can be increased, the water conveying pipes penetrating through the annular inclined grooves output high-pressure water flow so that the suction penetration resistance can be greatly reduced, rapid sinking can be realized, self-drilling anchor rods are arranged on the annular inclined groove at the uppermost layer so that the effect of the suction bucket can be further stabilized, and the uplift bearing capacity of the suction bucket foundation can be greatly improved.

The invention relates to a device and a method for treatment of domestic sewage with a DPR-MABR coupling reactor, and belongs to the field of wastewater treatment. The device comprises a raw water pool, a reaction pool I, a first intermediate water pool, a reaction pool II, a second intermediate water pool and a PLC (Programmable Logical Controller) control box, wherein two different series-connection systems are switched by virtue of the PLC control box, one of the series-connection system is an I-to-II series-connection system, the raw water pool is connected with the bottom of the reaction pool I by virtue of a water inlet pipe, the reaction pool I is connected with the first intermediate water pool by virtue of an I-to-II water outlet pipe, the first intermediate water pool is connected with the top of the reaction pool II by virtue of an I-to-II second water inlet pipe, and treated water is discharged from an I-to-II final water outlet pipe; the other system is an II-to-I series-connection system, the raw water pool is connected with the top of the reaction pool II by virtue of a water inlet pipe, the reaction pool II is connected with the second intermediate water pool by virtue of an II-to-I water outlet pipe, the second intermediate water pool is connected with the top of the reaction pool I, and treated water is discharged from the water outlet pipe. The device and the method have the advantages of high efficiency, energy conservation, stable nitrogen removal and dephosphorization effect and stable sludge reduction.
