Bedrock skirting protection device for bottom-seal-free rock-socketed steel sheet pile cofferdam
The invention discloses a bottom-sealing-free rock-socketed steel sheet pile cofferdam bed rock skirting protection device which comprises a foundation pile arranged on foundation pit hard rock, the periphery of the foundation pile is slotted in the foundation pit hard rock to form a notch, a cofferdam is formed by inserting Larsen steel sheet piles into the notch, multiple layers of surrounding purlins are evenly distributed on the inner side of the cofferdam from top to bottom, and the surrounding purlins are arranged on the periphery of the foundation pile. The structure further comprises a plurality of I-shaped steel, the I-shaped steel is arranged in the grooves of the Larsen steel sheet piles and faces the inner side of the cofferdam, and the I-shaped steel is located below the top of the notch foundation pit hard rock. The method has the advantages of clear mechanism, simple construction, low cost and the like.
本发明公开了一种无封底嵌岩钢板桩围堰基岩踢脚防护装置，包括设置在基坑硬岩上的基桩，所述基桩的外围在基坑硬岩进行开槽后形成槽口，所述槽口内通过插打拉森钢板桩形成围堰，所述围堰的内侧从上到下均布有多层围檩，还包括多个工字钢，多个所述工字钢设于所述拉森钢板桩的凹槽内，并朝向围堰的内侧，且所述工字钢位于所述槽口基坑硬岩的顶部以下；本发明具有机理明确，施工简单，成本低等优点。
