H-shaped steel structure for lap joint of underground diaphragm walls with different thicknesses
The invention relates to an H-shaped steel structure for lap joint of underground diaphragm walls with different thicknesses. An H-shaped steel connector structure (9) is arranged between a first-stage groove section (2) and a second-stage groove section (3), the H-shaped steel connector structure (9) is composed of flange plates (4), webs (5), transverse steel plates (6) and angle steel (7), one ends of the flange plates (4) on the upper side and the lower side of the H-shaped steel (9) are in lap joint with the first-stage groove section (2), and the other ends of the flange plates (4) on the upper side and the lower side of the H-shaped steel (9) are in lap joint with the second-stage groove section (3). The defects that in the prior art, a joint of an underground continuous wall is shorter in a thickness sudden change position and a surrounding seepage path compared with an equal-thickness underground continuous wall, and hidden dangers of water leakage and sand leakage exist are overcome, and the H-shaped steel structure has the advantages that holes are formed in the webs of the H-shaped steel, and the concrete pouring quality is improved, so that the joint water stopping effect is improved, and the excavation construction safety of a foundation pit is ensured.
本发明涉及到不同厚度地下连续墙搭接时的H型钢结构，所述的一期槽段(2)和二期槽段(3)之间设置有H型钢接口结构(9)，所述的H型钢接口结构(9)由翼缘板(4)、腹板(5)、横向钢板(6)和角钢(7)组成，所述的H型钢(9)上下两侧的翼缘板(4)一端搭接在一期槽段(2)，另一端搭接在二期槽段(3)上，它克服了现有技术中地下连续墙的接头在厚度突变处，绕渗途径相比等厚度的地下连续墙短，存在漏水漏砂的隐患的缺点，具有在H型钢的腹板上开孔，提高混凝土浇筑质量，从而达到提高接缝止水效果，确保基坑开挖施工安全的优点。
