摘要： A construction method for a cantilever beam on a central pier. A scaled model of the cantilever beam on the central pier is established and tested to obtain the stress distribution regularities of the cantilever beam according to test data and analysis results of the scaled model, so as to find out week parts of the cantilever beam, and thus the optimization design can be performed to make the cantilever beam reasonably carry the load and improve the materials with a higher utilization ratio. The wheeled stand support used in the present application has a high turnover rate and it is easy and convenient to dismantle and assemble the wheeled stand support. A height of the cantilever beam mold can be adjusted by a hydraulic cylinder.

摘要： The present application discloses a final joint of an immersed tunnel, a prefabrication method and an installation method, wherein the final joint includes two end surfaces connected with installed adjacent tube sections; the two end surfaces are both tilted surfaces, so that the longitudinal profile of the final joint along an installation direction is of an inverted trapezoid structure; and the final joint further may be of a structure with a tube section I and a tube section II which are connected with each other. The final joint of the immersed tunnel is simple in structure, convenient to control and relatively high in precision, thereby reducing lots of open sea diving work and lowering a risk of installation quality defects; as prefabrication procedures are simple, the final joint may be prefabricated in a land factory and then transported to the site, thereby reducing influence of weather conditions on construction; a body structure of the final joint is prefabricated in the factory, and then the overall final joint is transported to the site for installation; water stop systems realize quick water stop, thus forming a dry construction environment; and therefore, the influence of weather and tidal current conditions on a project may be reduced, and a quality risk may be lowered.

摘要： The present application relates to the field of immersed tube jointing, and more particularly relates to a post-grouting method for an immersed tube joint base. The post-grouting method includes the following steps: before locked backfilling of immersed tubes to be implanted, disposing a grouting tube capable of outputting solidifiable slurry in a furrow below immersed tubes; and after the locked backfilling, grouting the immersed tubes by using the grouting tube. For the purposes of adjusting postures and heights of the immersed tubes in case of abnormal settlement during installation, solving the problems on the stabilities and the service lives of immersed tube joints due to settlement of gravel mattresses or a geologic structure thereunder after installation, and enabling the immersed tubes to achieve a better bearing effect on a load during use, the present application provides the post-grouting method for the immersed tube joint base.

摘要： The present application discloses a bearing structural member, a support, a joint assembly and a tube section assembly, wherein the maximum counter force provided by the bearing structural member under an external load is an own designed threshold value, namely when the external load is greater than the designed threshold value of the bearing structural member, the bearing structural member deforms, and provides a counter force equal to the designed threshold value; the support includes at least one bearing structural member; and the joint assembly and the tube section assembly are both equipped with the support. When the external load is not high and is less than the designed threshold value, the bearing structural member may effectively suppress the deformation just like a rigid structural member; when the external load exceeds the designed threshold value, the bearing structural member may deform, and provide a stable counter supporting force less than the external load. The bearing structural member may be applied to the support, the joint assembly and the tube section assembly, plays a role in protecting the structures or key structural components, and may be widely applied to the fields of design of bridges, design of building structures, design of tunnels and the like.

摘要： The present application discloses a prestressed tube section structure and a construction method thereof. The prestressed tube section structure includes multiple successively connected segments. A shear-resistant structure and a water stop system are arranged between two segments; multiple prestressing tendons are arranged in the tube section along the circumferential direction of the tube section; and each prestressing tendon is communicated along the longitudinal direction of the tube section, and is partitioned into multiple sections at a position close to a segment joint. By the arrangement of the multiple successively connected segments of the present application, the shear-resistant structure and the water stop system are arranged between the two segments, so that a portion between two segments may bear a shear force and have watertightness; the arrangement of the multiple prestressing tendons in the tube section enables the multiple segments to be connected in series and spliced into a whole; in addition, each prestressing tendon is partitioned into multiple sections at the position close to each segment joint, so that the tube section has higher flexibility on the premise of not losing the overall rigidity, and the loading capacity and deformability of each segment are effectively improved; and a proper pressure is applied between two segments, so that the tube section has higher deformability to adapt to a subsea foundation bed.

摘要： The present application discloses an integrated immersed tube section and an installation method thereof, and an installation and closure method of immersed tube sections, wherein the integrated immersed tube section includes a standard immersed tube section; and closed annular telescopic water stop joints are arranged at two ends of the standard immersed tube section. By the adoption of the integrated immersed tube section of the present application, a finally closed immersed tube section is still the standard immersed tube section, and a foundation which is the same as that for common tube sections is used, namely the foundation for the finally closed immersed tube section and the foundation for other immersed tube sections do not have a rigidity difference, so that the risk of the non-uniform settlement of the tube sections during operation of the subsea tunnel is effectively reduced; and in addition, the finally closed immersed tube section and other immersed tube sections are installed with the same installation equipment, and no extra equipment such as a floating crane is needed. Compared with an existing method, the methods have the advantages of eliminating installation of one special final joint, simplifying the construction process and reducing the engineering risk. As offshore special construction equipment and ships are very expensive in rent, use of the integrated immersed tube section substantially reduces the cost and saves various resources.
