The invention discloses a self-sinking fish reef comprising a self-sinking support. The self-sinking support comprises a platform, a trapezoidal support frame is arranged below the platform, and the support frame is connected by side support rods on the side faces and a bottom support rod at the bottom. Limiting columns are arranged on the portion, on the inner sides of the side support rods, below the platform. A positioning boss protruding upwards is arranged on the portion of the upper side of the platform. Multifunctional tubes are arranged at the positions close to the edge of the positioning boss. A combined reef body is arranged above the platform, and comprises annular reefs matched with the edge of the positioning boss. Through positioning holes capable of accommodating pins are formed at the side positions, close to the tops or bottoms, of the annular reefs. The self-sinking fish reef has the advantages of high sinking speed, layout stability, high proliferation efficiency, high success rate and capability of replacing proliferation varieties as required.

The invention discloses a steel-concrete composite cylinder-type foundation structure and a construction method thereof. A concrete cylinder-type transition section with a cambered wall surface is arranged on a concrete top cover; a cylinder structure which is formed by a concrete cylinder wall and a steel cylinder wall is arranged on the lower side of the concrete top cover; air blow / water pipes are uniformly arranged in the concrete cylinder wall along the radial direction; and a steel subdivision plate is arranged in the internal space of the steel cylinder wall. The construction method comprises the following steps of: prefabricating the steel-concrete composite cylinder-type foundation structure on the land; transporting the whole foundation structure to a construction site in a floating mode, and performing self-weight sinking construction and negative pressure sinking construction; after the negative pressure sinking construction is stopped, performing groundbreaking sinking construction through the air blow / water pipes; and leveling by applying different in-cabin positive pressure onto all sub-cabins through a pump system when the foundation structure is inclined in the sinking process. The foundation structure can be extremely easily sunk into a soil body to reach a designed sinking depth by overcoming the resistance of the soil body, and the sinking speed and the sinking arrival rate of a cylinder-type foundation can be substantially improved, so that the construction period of a foundation structure system is shortened, and engineering cost is greatly reduced.

The invention discloses a method for preparing sodium fluoride from defluorination residue generated in production of phosphoric acid by a wet process. The method comprises the following steps of respectively recycling mother liquid, sodium carbonate and defluorination residue slurry, reacting and crystallizing the defluorination residue slurry and a sodium carbonate solution and simultaneously returning fine sodium fluoride particles to the system for secondary growth. By larger sinking speed difference between sodium fluoride and silicon dioxide, the separation of sodium fluoride from silicon dioxide is achieved, and the technical problem of difficulty in separation of sodium fluoride from SiO2 is effectively solved. The sodium fluoride product obtained by the method is coarse, more than 85% of the sodium fluoride product has particle diameter greater than 0.35mm and the yield of fluorine in the sodium fluoride product is above 85%. By the method, the circulation of the mother liquid is achieved, the water consumption as well as the production cost are decreased, and the method has good social and economic values and is suitable for being popularized and applied.

The invention discloses a movable prefabricated multi-barrel type gravity mixed foundation, comprising a plurality of barrel-type foundations which are axially arranged in parallel and share common surface on a barrel cover, wherein an upper barrel-type structure with an upward opening is coaxially and fixedly connected with the barrel-type foundation by the barrel cover thereon; a connecting bottom plate and rib plates which are connected into a whole with the barrel covers of the plurality of barrel-type foundations are used for connecting the upper barrel-type structures; the bottom surface of the connecting bottom plate has common surface with the bottom surface of the barrel cover of the barrel-type foundation; a foundation bearing platform positioned at the mixed foundation center is arranged on the connecting bottom plate; the barrel body of each upper barrel-type structure is filled with heavy objects; and the barrel cover of the barrel-type foundation is provided with reserved through hole capable of being opened and closed. The movable prefabricated barrel-type gravity mixed foundation does not need large transport ships when in transportation, and site installation doesnot need large hoisting ships; and the positioning and sinking equipment is simple, the construction is simple and convenient, the sinking speed is fast, the skewness is easily controlled, the vacuumpre-pressing and heavy objects filling have significant pre-pressing effect to foundation consolidation and the comprehensive engineering cost is low.

The present invention is the marine air floatation hauling and locating and depositing installation process of case and barrel shaped foundation structure for soft soil. The construction process includes inflating the case and barrel shaped foundation structure in water for it to float and hauling to the installation site; locating in the floating state; deflating for deposition via controlling the deflation speed and amount to control the deposition speed and inclination; pumping out air from the structure and applying pressure for further deposition; pumping out water from the structure for further deposition until pumping out all water inside the structure and completing the installation. The said process needs no large hoisting and transportation apparatus, and is simple, controllable and low in cost.

The invention discloses a movable prefabricated cylindrical gravity hybrid foundation, which comprises a cylindrical foundation, a foundation cap is fixedly connected to the center of the upper surface of the cylindrical foundation, and the upper surface of the cylindrical foundation is coaxial An upper cylindrical structure with an upward opening is fixedly connected, and the interior of the upper cylindrical structure is divided into multiple chambers by reinforcing ribs arranged between its cylinder wall and the foundation cap; the interior of the cylindrical foundation It is divided into multiple chambers through the reinforcing ribs provided under the cylinder cover. Each chamber of the cylinder foundation is provided with a switchable reserved through hole on the cylinder cover of the cylinder foundation. The upper cylinder Each chamber of the structure is filled with a weight. The invention does not require a large transport ship for transportation, and does not require a large hoisting ship for on-site installation; the positioning sinking equipment is simple, the construction is simple, the sinking speed is fast, the deflection is easy to control, and the vacuum preloading and heavy object filling preload the foundation reinforcement. The effect is outstanding, and the comprehensive engineering cost is low.

The invention relates to the technical field of hydrometallurgy, in particular to a method for back extraction of germanium from a germanium-contained fluosilicic acid solution. The germanium-contained fluosilicic acid solution is extracted with an N235-kerosene system serving as an organic phase, a sodium hydroxide solution containing ammonium ions is adopted for treating the organic phase, sulfuric acid is added to a back extraction solution to adjust the PH value, then, germanium hydrolysis treatment is performed, obtained precipitate is calcined, germanium is obtained, and the quality of germanium concentrate is further improved, so that in the germanium concentrate, the content of germanium is larger than or equal to 7%, the content of F is smaller than 0.5%, and the content of Si is smaller than 4%; the extraction rate of germanium in germanium-contained fluosilicic acid is increased, and the extraction cost of germanium in the germanium-contained fluosilicic acid solution is reduced.
