Construction method of pool body structure under soft soil texture in coastal area
The invention relates to a construction method for a pool body structure under soft soil texture in a coastal area. The construction method comprises the following steps that Larsen steel sheet piles are driven on the planned edge of a preset pool body structure in the circumferential direction till the Larsen steel sheet piles penetrate through a soft soil layer to be anchored and enter a soil layer below the soft soil layer; a foundation pit is excavated in a soft soil layer, and more than two layers of inner supports are arranged in the Larsen steel sheet piles to form a space inner supporting system; bottom layer replacement and cushion layer pouring are conducted on the bottom of the foundation pit, and support replacement belt concrete between a pool bottom plate and the Larsen steel sheet piles is poured; and underground pool body structure construction is conducted in the foundation pit. According to the construction method of the pool body structure under the soft soil texture in the coastal area, the Larsen steel sheet piles are fully anchored to enter the lower bearing layer of the soft soil layer, foundation pit supporting is conducted, the excavated foundation pit forms a stable space three-dimensional supporting structure, lateral bending stress deformation of the middles of the Larsen steel sheet piles is resisted, and the construction quality of the pool body structure under the soft soil texture in the coastal area is improved. And the safety and rationality of construction of the deep foundation pit of the underground pool body are ensured.
本申请涉及一种沿海地区软土地质地下池体结构施工方法，包括以下步骤：在预设池体结构的规划边沿周向打设拉森钢板桩至穿透软土层锚固进入软土层以下土层；在软土层开挖基坑，并在拉森钢板桩内设置二层以上内支撑，形成空间内支撑体系；将基坑的底部进行底层换填和垫层浇筑，并浇筑池底板和拉森钢板桩之间的换撑带混凝土；在基坑内进行地下池体结构施工。本申请提供的沿海地区软土地质地下池体结构施工方法，通过拉森钢板桩充分锚固进入软土层下层持力层中并进行基坑支护，使得开挖的基坑形成稳定的空间立体支撑结构，抵抗拉森钢板桩中部侧向的弯曲受力变形，确保地下池体深基坑施工的安全性、合理性。
