Construction method of foundation precast concrete cushion
The invention relates to the technical field of building construction, and discloses a construction method of a foundation precast concrete cushion layer, which comprises the steps of paying off and positioning a foundation bearing platform, prefabricating the concrete cushion layer, excavating earth, rechecking the size and elevation of the bearing platform foundation, hoisting the precast concrete cushion layer, adjusting the hoisting precision, checking and accepting and the like. Through the construction method of using the prefabricated concrete cushion in the water-rich foundation, the stability of the concrete cushion is ensured, and the problems of cushion arching, deformation, cracking and the like caused by disturbance of concrete of the water-rich foundation in a traditional construction method are remarkably solved. According to the method, uncertainty caused by waiting for concrete solidification in a traditional construction method is avoided, the concrete is allowed to be prefabricated in advance, and hoisting positioning is conducted immediately after excavation is completed. The construction efficiency is improved, and the overall construction progress is accelerated.
本发明涉及建筑施工技术领域，公开了一种地基预制混凝土垫层的施工方法，包括基础承台放线定位、混凝土垫层预制、土方开挖、承台基础尺寸及标高复核、预制混凝土垫层吊装、吊装精度调整、验收等步骤。通过在含水量丰富地基中使用预制混凝土垫层的施工方法，确保了混凝土垫层的稳定性，显著改善了传统施工方法中因含水量丰富地基混凝土扰动导致的垫层起拱、变形和裂缝等问题。这种方法避免了传统施工方法中因等待混凝土凝固而产生的不确定性，允许混凝土提前预制，并在开挖完成后立即进行吊装定位。这不仅提高了施工效率，还加快了整体的施工进度。
