Supporting and protecting pile protection structure for deep foundation pit construction in coastal silt zone
The invention discloses a supporting and protecting pile protection structure for deep foundation pit construction in a coastal silt zone in the field of deep foundation pit construction. The supporting and protecting pile protection structure comprises a deep foundation pit, a supporting and protecting pile positioned in the deep foundation pit and a bearing platform positioned at the bottom of the deep foundation pit, a steel molding bed for supporting a surrounding silt soil layer is arranged in the bearing platform, the steel molding bed is made of a steel material, a concrete cushion layer is laid at the bottom of the steel molding bed, bottom plate concrete is laid at the bottom of a foundation pit, the bottom plate concrete is located in the bearing platform and on the upper part of the surrounding sludge soil layer, and waterproof coiled materials are arranged between surface of the steel molding bed and the bottom plate concrete and between the surface of the concrete cushion layer and the bottom plate concrete respectively. According to the supporting and protecting pile protection structure for the deep foundation pit construction in the coastal silt zone, a basic excavation area of the bearing platform is directly formed after the steel molding bed is pressed into the silt, so that flowing of the silt does not affect forming of the bearing platform, and therefore the more convenience in construction is guaranteed; meanwhile, due to the design of the position and the size of the steel molding bed, the interior of the foundation pit cannot form a large excavation pattern, the supporting and protecting pile in the foundation pit are supported is guaranteed, and the stability of the supporting in the foundation pit is guaranteed.
本发明公开了深基坑施工领域中的一种用于沿海淤泥地带深基坑施工的支护桩保护结构，包括深基坑、位于深基坑内部的支护桩、位于深基坑底部的承台，承台内设有支撑周围淤泥土层的钢胎模，钢胎模由钢材质制成，钢胎模的底部铺设有混凝土垫层，基坑的底部铺设有底板混凝土，底板混凝土位于承台内部及周围淤泥土层的上部，钢胎模表面与底板混凝土之间、混凝土垫层的表面与底板混凝土之间均铺设有防水卷材。本发明的钢胎模压入淤泥后直接形成承台的基本开挖区域，使得淤泥流动也不会影响承台的成型，进而保证施工更加方便；同时由于钢胎模位置及大小的设计，使得基坑内部不会形成大开挖的形式，保证基坑内部支护桩得到支撑，保证了基坑支护的稳定性。
