Foundation reinforcement treatment method and reinforcement structure for equipment foundation in factory building
The invention provides a foundation reinforcement treatment method and a reinforcement structure for an equipment foundation in a factory building. The foundation reinforcement treatment method and the reinforcement structure are used for construction of a factory building equipment dense area, are fast in construction and reliable in quality. The reinforcement treatment method comprises the following steps that 1, working pits are dug, specifically, three working pits are dug on site; 2, pile pressing is conducted, specifically, pile repairing is conducted through the three pits, and pile pressing is conducted above the bottoms of the pits in three excavation holes; 3, the equipment foundation is jacked, specifically, after pile pressing construction is completed, the equipment foundation is jacked, a jack is placed between the equipment foundation and a reinforced concrete pile section, and the equipment foundation is jacked; 4, underpinning is conducted, specifically, after the equipment foundation is jacked and reset, underpinning is conducted immediately through an underpinning steel pipe, and firm welding is conducted; 5, a pile head is sealed through concrete, specifically, concrete is poured on the underpinning steel pipe portion, and the reinforced concrete pile section and the equipment foundation are connected into a whole; and 6, backfilling is conducted, specifically, the void part at the bottom of the equipment foundation is subjected to backfilling treatment through 2: 8 lime soil or cement soil, and after filling is completed, the opening of the working pit is repaired through concrete.
本发明提供一种厂房内设备基础地基加固处理方法及加固结构，用于厂房设备密集区施工，施工快，质量可靠，所述加固处理方法包括：步骤1、挖工作坑，现场开挖三个作业坑；步骤2、压桩，通过三个坑进行补桩，在三个开挖孔内坑底上方压桩；步骤3、设备基础顶升，待压桩施工完成后，再进行设备基础顶升，将千斤顶置入设备基础和钢筋混凝土桩段之间，对设备基础进行顶升；步骤4、托换，待设备基础顶升复位后，立即用托换钢管进行托换并焊接牢固；步骤5、混凝土封桩头，在托换钢管部位用砼进行浇筑，使钢筋混凝土桩段与设备基础连成一体；步骤6、回填，设备基础底部脱空部分用2：8灰土或水泥土回填填充处理，填充完成后，将作业坑坑口用砼修复。
