The foundation (comprising annular and radial wall parts) of the upright column 201 is integrally horizontally prefabricated and is lifted and turned over by a high-low gantry crane, stored in a storage yard and installed on a general assembly platform. The upright 201 is a main stress member and bears various horizontal forces and bending moments, vertical steel bars must be continuous or joint force transmission is continuous and reliable, the upright 201 adopts the whole horizontal binding of a steel reinforcement cage, a horizontal prefabrication process, a workshop internal steam maintenance process, a workshop external turning process and a site storage process. The bottom of the upright column 201 is provided with vertical steel bars and horizontal steel bars connected with the top plate 102. Reservation in the middle of the column 201 wall the pull rod 203 is connected with the hole.
Prefabricating the circular arc sheets, wherein the vertical circumferential dimensions of the circular arc sheets are equal, a part of the circular arc sheets are provided with water permeable holes 221, pouring and curing the circular arc sheets on a special die table, turning over after the circular arc sheets reach preset strength, and piling up the circular arc sheets outside a workshop. Workshop pipelining, 24 hours of operation, intelligent degree is high, and industry workman's recruitment is few, and the time limit for a project has the guarantee, and product quality is high and stable, green, energy-conserving.
The pull rod 203 is prefabricated, and is integrally prefabricated in a workshop, and a cast-in-situ reinforcing steel bar head is reserved at the joint of the pull rod 203 and the upright 201.
When the embankment body structure 20 is assembled, the appearance assembly is completed according to the sequence of the upright posts 201 and the arch rings 202, the overall verticality and ellipticity are checked to meet the requirements, the pull rod 203 is installed, the check is qualified again, the cast-in-place concrete of each joint is completed on the general assembly platform, and finally the upright posts 201 are prestressed to seal the connecting holes of the pull rod 203, so that the general assembly of the embankment body structure 20 is completed.
In this embodiment, the dike body structure 20 has a relatively simple composition, and includes the upright posts 201, the arch rings 202 and the pull rods 203, and each part has a single dimension specification, so that the prefabrication process and the mold table variety are greatly simplified.
Outfitting, namely pre-outfitting prefabricated components, wherein the pre-outfitting comprises the steps of arranging an open pore sealing plate and transporting and installing auxiliary facilities.
And (3) carrying out shipment, namely selecting a good seawater window, rolling on a semi-submersible barge or a semi-submersible ship by using an SPMT heavy module vehicle, carrying out cabin sealing operation, fixedly finishing, exiting the module vehicle, and towing and shipping to the site. And (5) submerging at the designated position, and moving the structural object 1 out of the semi-submerged barge to complete the transportation task.
And (3) installing the steel plates one by one from strong waves to the beginning according to the site construction sequence. The installation process controls the position, the verticality and the elevation.
The construction method of the breakwater structure with the wave eliminating function solves the problem of shortage of construction land supply of a super-large structure prefabrication factory, saves a large amount of land by prefabrication in a factory method, is prefabricated by a small-piece factory, is of a total composition type, solves the problem of shortage of large-scale hoisting equipment in a workshop, realizes workshop standardized production of concrete components, improves efficiency and quality, solves the problem of shortage in construction period, solves the problems of large-scale component reinforcement difficulty, difficult quality control and inspection, is simple in small-piece prefabrication, is large in turnover number, is green, saves energy and is environment-friendly, and improves the intelligent level through visual central intelligent control.
The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the application.
