The invention discloses geopolymer concrete based on household garbage incineration slag and red mud and a preparation method of the geopolymer concrete, and the preparation method comprises the following steps: respectively carrying out first pretreatment on the household garbage incineration slag and the red mud to obtain first pretreated slag and first pretreated red mud, then carrying out second pretreatment to obtain second pretreated slag and second pretreated red mud, uniformly mixing the first pretreated furnace slag, the first pretreated red mud and the municipal dewatered sludge, granulating to obtain a green body, drying the green body, then carrying out first heating, then cooling to obtain porous lightweight aggregate ceramsite, carrying out second heating on the second pretreated red mud, then cooling so that modified red mud is obtained, uniformly mixing the second pretreated furnace slag, the modified red mud and an alkali activator to obtain geopolymer powder, adding water into the geopolymer powder, uniformly mixing, adding the porous lightweight aggregate ceramsite, and uniformly mixing to obtain the geopolymer concrete. The utilization rate of red mud, waste incineration slag and municipal sludge can be increased, and environmental pollution is reduced.

The invention relates to the technical filed of ultra-abyssal-sea multicellular organism fidelity sampling, and in particular to a bidirectional piston type abyss multicellular organism trapping and fidelity sampling device. The bidirectional piston type abyss multicellular organism trapping and fidelity sampling device comprises a bottom plate, wherein a sampling device, an underwater decelerator, a deep water motor, a control cabinet and an energy accumulator are uniformly distributed on the bottom plate; the sampling device comprises a pressure maintaining cylinder and a guiding cylinder which are connected through a flange; two ends of the pressure maintaining cylinder are opened; a sampling piston is arranged in the pressure maintaining cylinder, a cavity is formed in the sampling piston, a penetrated square opening is formed in the middle part of the sampling piston, and a sampling pipe is arranged in the cavity; two ends of the guiding cylinder are opened; the front end of the guiding cylinder is connected with the pressure maintaining cylinder through the flange, and the rear end of the guiding cylinder is connected with the connecting cylinder; the input end of the underwater decelerator is connected with the deep water motor; the energy accumulator is connected with the pressure maintaining cylinder through a capillary; and the control cabinet is connected with the underwater decelerator and the deep water motor through a watertight cable. Through the adoption of the bidirectional piston type abyss multicellular organism trapping and fidelity sampling device disclosed by the invention, pressure maintaining sampling can be completed, so that the obtained biological samples are guaranteed to be fundamentally kept in the in-situ pressure, and the survival rate oforganisms is greatly increased.

The invention relates to a light filled core bamboo tube structure. The light filled core bamboo tube structure comprises a light filled core (1), a bamboo tube (2) and reinforced bamboo belts (3), wherein a cavity of the bamboo tube (2) is provided with the light filled core (1), the bamboo tube (2) is formed by mutually compounding a longitudinal bamboo band (21) and a bamboo coiled material (22); and the reinforced bamboo belts (3) are adhered to the outer wall of the outer wall of the bamboo coiled material (22) in a spiral or loop type internal winding manner so as to form included anglesof (-45)-(45) degrees or 0 degree with the direction of the cross section with the bamboo tube (2). According to the light filled core bamboo tube structure, a lateral support force is provided for the tube wall of the bamboo tube from side to outside by the light filled core, so that the inward local buckling of the bamboo tube is prevented or delayed, and the bearing force of the bamboo tube isgreatly increased; and the annular constraint force is provided for the light filled core by the bamboo tube, so that the stressed bearing capacity of the light filled core is improved, and the transverse deformation of the light filled core is reduced. The light filled core bamboo tube structure is suitable for components such as piles, columns, piers and beams in newly built structures.

The invention belongs to the field of integral buildings, and in particular relates to a steel structure toilet. Including detachable wall panels, steel-structured water-side crystal porcelain plate composite honeycomb core waterproof chassis; steel-structured ceiling, structural support, inorganic decorative integrated panels, as well as sinks, sanitary ware, hardware and electrical appliances, etc., it is characterized in that: all The support structure of a steel structure toilet adopts an integrated all-steel structure, which ensures the firmness and durability of the toilet. The main keel and auxiliary keel of the support structure are coupled and locked by the rotary latch and the knob lock. The steel structure toilet The wall board and the floor are made of inorganic decorative integrated board, which has the characteristics of high wall strength, high water resistance, fire resistance, wear resistance and light weight. The board is equipped with a buckle system, which can make the board directly hang on the supporting structure, subversive It replaces the traditional board installation method, thereby ensuring the safety of the toilet and the simplicity of construction, and also saving a lot of manpower and material resources for subsequent maintenance.

The invention relates to a super-silent drawer. The super-silent drawer includes a bottom plate and side plates; the bottom plate is perpendicular to the side plates, and the side plates surround the four sides of the bottom plate; a handle is arranged on one of the side plates, the upper surface of the bottom plate is provided with a flexible buffering cavity, the buffering cavity is filled with buffering particles, supporting plates are fixedly distributed on the upper surface of the buffering cavity in an equidistant array mode, and every two supporting plates do not contact with each other; a cleaning rolling shaft is arranged on the buffering cavity and the bottom plate and parallel to the long side of each supporting plate, a driving roller meshed with cleaning rolling shaft is arranged on the bottom plate, and under the driving of the driving roller, the cleaning rolling shaft can roll along the short side of each supporting plate in a reciprocating mode. The drawe is novel and unique in structure, and can effectively reduce the noise generated by the drawer when items are rummaged and effectively prevent noise from disturbing others.

The invention discloses a decorative shell for a notebook computer, which comprises a host shell, and the host shell is provided with a mounting groove for mounting a circuit board, a CPU, a display card and a memory bank. Extension parts of a prism structure are symmetrically arranged at the end, close to the screen shell, of the host shell, and a rotating shaft used for being connected with thescreen shell is rotationally arranged between the extension parts. Each extension part comprises a hollowed-out decoration part and a rotating shaft connecting part which are integrally formed, and the hollowed-out decoration part is located on the side, away from the rotating shaft, of the rotating shaft connecting part. A decorative groove used for installing a light-emitting element is formed in the hollowed-out decorative part, and the decorative groove is communicated with the mounting groove through a through groove located in the host shell. And a wiring terminal used for connecting thelight-emitting element and the circuit board is arranged in the through groove. According to the decorative shell, the exterior decoration performance of the notebook computer is enhanced while the lightness and thinness of the notebook computer are guaranteed.
