The invention discloses a desert-sand light aggregate concrete fabricated shear wall structure which comprises a foundation, coupling wall columns arranged on the foundation, and coupling beams connected between the coupling wall columns. The coupling wall columns are mainly composed of steel wire nets, thin-wall shape steel, steel wire cages and the like correspondingly. Desert-sand light aggregate concrete is poured on the steel wire nets and the steel wire cages, and the coupling wall columns are connected through asbestos boards, the steel wire nets, the desert-sand light aggregate concrete and the like in a poured mode correspondingly. The desert-sand light aggregate concrete fabricated shear wall structure is light in weight, materials are easy to obtain, the anti-seismic bearing capacity and deformability of components can be reliably ensured, and the good heat-insulating property is also achieved under the situation that the bearing requirement is met. The assembly attributes of simple structure and convenient and rapid transporting and mounting are achieved, and the desert-sand light aggregate concrete fabricated shear wall structure is particularly suitable for remote villages and towns which are insufficient in material supply, low in worker quality and short in technical force in Xinjiang region, and can be self-built by tile teams or farmers of the villages and thetowns.

The invention proposes a construction method for a large-diameter steel-concrete composite cylindrical structure, comprising the following steps: making a steel cylinder and dowel bars: making a steel cylinder and a plurality of dowel bars, A gap is opened at the lower end of the steel cylinder; the installation of the dowel rod and the steel cylinder: the dowel rod is vertically inserted into the upper end of the steel cylinder through the gap to fix it; the installation of the support structure: the support structure includes A plurality of support rods arranged horizontally, one end of each support rod is respectively connected with a dowel rod, and the other end of the support rod intersects and is fixed on the central axis of the steel cylinder; the production and installation of the ring substitute: The ring-shaped substitute is fixedly connected with the upper end of the dowel bar; vibration and sinking construction: install the vibration-sinking tool for vibration-settling, and remove the ring-shaped substitute and supporting structure after the vibration-settling construction is completed; prefabrication of the concrete cylinder and installation of the concrete cylinder. The construction method can effectively reduce the construction cost, is easy to engineer and manufacture, and the obtained cylindrical structure has strong durability.

The invention discloses a bionic bridge pier and a construction method thereof. The bionic bridge pier comprises a bridge pier body arranged on a foundation of the bridge pier, wherein the bridge pier body comprises a solid pier bottom section, a hollow pier body section and a branch-shaped pier top section which are sequentially connected from bottom to top, the branch-shaped pier top section comprises a plurality of pier branches which are arranged on the upper end surface of the hollow pier body section in a symmetric or non-symmetric manner and extend obliquely and upwards, the hollow pier body section comprises prestressed steel strands and a plurality of hollow pier body blocks, adjacent hollow pier body blocks are in positioned mortise-and-tenon joint, the prestressed steel strands are arranged in the side walls of the hollow pier body blocks and penetrate through the hollow pier body section, the lower ends of the prestressed steel strands are anchored in the solid pier bottom section, each pier branch comprises multiple groups of assembling components and a plurality of prestressed ribs, the assembling components are in positioned mortise-and-tenon joint, the cross section of each pier branch is a solid or hollow section, two adjacent assembling components are anchored through the prestressed ribs arranged in the assembling components, and the assembling component at the bottommost end of each pier branch is anchored on the upper end surface of the hollow pier body section through the prestressed ribs arranged in the assembling components.

The invention provides a method for assembling a whole offshore wind turbine at a wharf. In the process of assembling a wind turbine, a main crane is placed on the ground at a extension line of the center line of a transport ship,when impellersare hoisted in accordance with specific conditions (that is,a high slack tide or a low slack tide period) and a certain rotation angle of an engine room, interference between a lifting arm of the main crane and the impellers during hoisting can be effectively avoided, and the bad influence of offshore waves generated during impeller hoisting can be effectively avoided,after the impellersare installed, the impellersare rotated to an inverted Y-shaped state, the interference between the impellers and the lifting arm of the main crane can be further avoided, and the center of gravity of the whole wind turbine can be made to relatively lower at the same time, the fact thatthe interference between a lifting hook and blades of the impellersis not generatedwhen the whole machine is hoisted in an installation position of the offshore wind turbine is met, and collision between the main crane and the blades when the main crane holds upa mast during assembling the impellers on an adjacent station can be further avoided.
