Immersed tube joint SPMT vehicle floating-state barge-up construction method
The invention relates to an immersed tube section SPMT vehicle floating-state barge-up construction method, which comprises the following steps: after a reinforced concrete immersed tube section is prefabricated, arranging an SPMT vehicle below the immersed tube section, arranging distribution beams on the SPMT vehicle, enabling the distribution beams to be distributed at intervals along the longitudinal direction of the immersed tube section, enabling the distribution beams to be transversely arranged along the immersed tube section, and then arranging first cushion blocks on the distribution beams, according to the invention, the distribution beam is provided with the corresponding first cushion blocks below the middle wall and the side wall of the immersed tube joint, the supporting force of the SPMT vehicle is distributed to the first cushion blocks through the distribution beam, and the supporting force is transmitted to the side wall and the middle wall of the immersed tube joint through the first cushion blocks, so that more SPMT vehicles can be arranged below the immersed tube joint, and the service life of the immersed tube joint is prolonged. The overall bearing capacity of the SPMT vehicle is larger than or equal to the overall load of the immersed tube joint, the distribution beam and the first cushion block, the transportation requirement is met, the situation that transportation cracking of the immersed tube joint is caused due to the fact that the SPMT vehicle is not located below the side wall and the middle wall of the immersed tube joint is avoided, and the SPMT vehicle can be used for carrying out barge transportation on the immersed tube joint.
本发明涉及一种沉管管节SPMT车浮态上驳施工方法，通过在钢筋混凝土沉管管节预制后，在沉管管节下方布设SPMT车，在SPMT车上设置分配梁，使得分配梁沿沉管管节的纵向间隔分布，且使得分配梁沿沉管管节横向设置，再在分配梁上设置第一垫块，使得分配梁在沉管管节的中墙和侧墙下方均设置有对应的第一垫块，通过分配梁将SPMT车的支撑力分配到第一垫块上，并由第一垫块传递至沉管管节的侧墙和中墙处，进而使得能够在沉管管节下方布置的SPMT车数量更多，使得SPMT车整体承载力大于或等于沉管管节、分配梁和第一垫块的整体荷载，满足运输需求，且不会因为SPMT车不在沉管管节侧墙和中墙下方而造成沉管管节的运输开裂，使得能够使用SPMT车对沉管管节进行上驳运输。
