Larsen steel plate and prestressed steel beam composite pile structure and construction method thereof
The invention discloses a Larsen steel plate and prestressed steel beam composite pile structure and a construction method thereof. The structure comprises Larsen steel plate sections and prestressedsteel beams, each Larsen steel plate section comprises multiple sedimentary Larsen steel plates and reinforcing mechanisms arranged on the excavated sides of the Larsen steel plates, and the reinforcing mechanisms comprise I-shaped steel parts, steel cushion plates and brackets. The method comprises the following steps that 1, construction preparing and Larsen steel plate stockpiling are conducted; 2, Larsen steel plate pile sinking is conducted; 3, prestressed hole drilling is conducted; 4, prestressed steel beam penetrating is conducted; 5, reinforcing mechanism construction is conducted; 6,prestressed steel strand tensioning, grouting and anchor sealing are conducted; and 7, the steps from 3 to 6 are repeatedly conducted multiple times, earth excavation is conducted multiple times, andinstallation of the multiple prestressed steel beams is completed. According to the Larsen steel plate and prestressed steel beam composite pile structure and the construction method thereof, the Larsen steel plates do not need inner steel supports, soil bodies are reinforced through the prestressed steel beams, soil body anti-sliding is eliminated, soil body deformation and displacement are controlled, and the strength, the rigidity and the stability of steel plate piles are improved.
本发明公开了一种拉森钢板和预应力钢束复合桩结构及其施工方法，该结构包括拉森钢板段和预应力钢束，每个拉森钢板段包括多个沉降的拉森钢板和设置在拉森钢板开挖侧的加固机构，所述加固机构包括工字钢部件、钢垫板和托架；该方法包括以下步骤：一、施工准备及拉森钢板的堆存；二、拉森钢板的沉桩；三、预应力孔的钻设；四、预应力钢束的穿设；五、加固机构施工；六、预应力钢绞线的张拉、注浆及封锚；七、多次重复步骤三至步骤六，进行多次土方开挖，完成多道预应力钢束的安装。本发明拉森钢板不需要内钢撑，利用预应力钢束加固土体、消除土体抗滑移、控制土体变形和位移，提高了钢板桩强度、刚度和稳定性。
