The invention discloses an underground engineering pit enclosure wall. The wall comprises at least two rows of multi-row support structure; the multi-row support structure comprises at least two special sectional steels; the special sectional steel comprises an abdominal plate and wing edges located on both sides of the abdominal plate; one or two wing edges of the special sectional steel are fixed with grooved joint slots; the special sectional steel is connected with adjacent special sectional steels in a inserting mode through the grooved joint slots; and each row of the multi-row support structure forms the underground engineering pit enclosure wall together with in-between original soil body or reinforced soil body that has been treated. According to the invention, because a pluralityof rows of special sectional steels in the pit enclosure wall are deformed and subjected to force together, the mechanical properties and anti-deformation ability of the pit enclosure wall is improved, and the cantilever depth of the cantilever-type support system is significantly increased or the number of support paths of the pile support system is effectively reduced.
本发明公开了一种地下工程基坑围护墙体，包含：至少两列多排支挡结构；所述的多排支挡结构包含有至少两个特殊断面型钢，所述的特殊断面型钢包含腹板和位于腹板两侧的翼缘，其一侧翼缘或者其两侧翼缘固定设置有槽榫连接件，所述的特殊断面型钢通过槽榫连接件与相邻的特殊断面型钢抽插式连接；所述的每列多排支档结构与位于其间的原状土体或经处理后的加固土体共同形成地下工程基坑围护墙体。本发明中基坑围护墙体内的多排特殊断面型钢共同变形和受力，从而提高基坑围护墙体的力学性能以及抗变形能力，显著加大悬臂式支护体系的悬臂深度或有效减少桩撑式支护体系基坑围护墙体的支撑道数。
