Construction method of wall block in immersed tunnel steel shell
The invention relates to the technical field of tunnels, in particular to a construction method of a wall block in an immersed tunnel steel shell. The construction method comprises the following steps: spliced plates are welded to form a middle wall inner panel, and a first longitudinal rib and a partition plate are welded to one side of the middle wall inner panel to form a frame; back firing annealing is conducted on the frame; spliced plates are welded to form a middle wall outer panel, and a second longitudinal rib is welded to one side of the middle wall outer panel to form a plate unit;back firing annealing is conducted on the plate unit; the plate unit is fixedly arranged on a jig frame; the frame is hoisted and fixedly arranged on the plate unit, and the side face, welded to the first longitudinal rib, of the frame faces the side face, welded to the second longitudinal rib, of the plate unit; the frame and the plate unit are welded to form a middle wall block; the middle wallblock arranged on the jig frame is annealed; and the annealed middle wall block is detached from the jig frame, and construction of the middle wall block is completed. According to the construction method, the stress generated by welding can be eliminated in the process of welding and manufacturing the middle wall block.
本发明涉及隧道技术领域，尤其涉及一种沉管隧道钢壳中墙块体的建造方法，其包括如下步骤：拼板焊接形成中墙内面板，在中墙内面板的一侧焊接第一纵骨和隔板形成框架；对框架进行背烧退火；拼板焊接形成中墙外面板，在中墙外面板的一侧焊接第二纵骨形成板单元；对板单元进行背烧退火；将板单元固定设置在胎架上；吊运框架，将框架固定设置在板单元上，且焊接有第一纵骨的侧面朝向板单元焊接有第二纵骨的一侧；对框架和板单元进行焊接组成中墙块体；对设置在胎架上的中墙块体进行退火；将退火后的中墙块体从胎架上拆卸下来，完成中墙块体的建造。本发明能够消除在焊接制造中墙块体的过程中，消除焊接产生的应力。
