Bailey beam anti-torsion foundation pit underwater excavation platform
The invention relates to a Bailey beam anti-torsion foundation pit underwater excavation platform. The platform is used for constructing by a rotary drilling rig, provided with excavation openings, and characterized by comprising two Bailey beams arranged on the two sides of each excavation opening, transverse trusses, a platform upper truss and a platform lower truss, wherein each Bailey beam iscomposed of a plurality of Bailey pieces, and the length of each row of Bailey pieces corresponds to the length of the platform upper truss. The Bailey beam anti-torsion foundation pit underwater excavation platform has the beneficial effects that due to the adoption of a truss consisting of the Bailey beams and section steel, the excavation platform has a good bearing function; limiting blocks are arranged on the portions, between every two adjacent Bailey pieces, of the platform upper truss and the platform lower truss, and wedge blocks are arranged among the Bailey pieces, so that the horizontal displacement amplitude of the Bailey beams is reduced; opening anti-torsion components are arranged at the excavation openings, so that the horizontal load resisting capacity of the excavation platform is remarkably improved; and the structure of the excavation platform can be assembled on the ground and integrally hoisted, the excavation platform is convenient to disassemble and can be recycled, engineering cost can be remarkably saved, cost can be reduced, and waste can be avoided.
本发明涉及一种贝雷梁抗扭基坑水下开挖平台，用于旋挖钻机施工，设有开挖洞口，其特征在于，包括两件设置在所述开挖洞口两侧的贝雷梁、横向桁架、平台上部桁架和平台下部桁架，每件所述贝雷梁由多片贝雷片构成，每行贝雷片的长度对应于所述平台上部桁架的长度。本发明的有益效果是：采用贝雷梁与型钢组成的桁架，使开挖平台具有良好的承重功能，平台上部桁架、平台下部桁架在相邻两所述贝雷片之间设有限位块，在贝雷片之间设置楔块，降低贝雷梁水平位移的振幅；在开挖洞口处设置洞口抗扭构件，可显著提高开挖平台抵抗水平载荷的能力；开挖平台的结构可地面拼装、整体吊装，方便拆卸，可重复利用，能显著节约工程造价，降低成本，避免浪费。
