Power distribution network steel pipe pole digging foundation and construction method thereof
The invention provides a power distribution network steel pipe pole digging foundation and a construction method thereof, and belongs to the technical field of power distribution network overhead line power equipment foundations of 20 kilovolts and below. Comprising the steps that the foundation position and excavation foundation parameters of the steel pipe pole are determined; positioning the steel pipe pole and re-measuring and separating pits; carrying out foundation earth excavation and diameter expansion on the excavated part according to the excavated foundation parameters; pouring a foundation cushion layer after leveling the foundation pit bottom; main reinforcements and stirrups are arranged in the excavated foundation and bound into a reinforcement cage, and connection of the main reinforcements and foundation bolts is completed in advance; pouring steel pipe pole foundation concrete; foundation bolts and flange plates are pre-buried; plastering and calendaring the top of the foundation; and after the steel pipe pole is assembled, pouring a foundation protective cap and manufacturing and mounting a pole tower in a grounding manner. According to the method, the transportation cost of earthwork excavation and residual soil outward transportation is reduced, formwork erecting, formwork dismounting and backfilling parts in foundation pouring can be omitted, and the concrete amount is relatively moderate; construction safety risks are easy to control, environmental pollution is low, the construction period is short, and manufacturing cost is low.
本发明提供配电网钢管杆掏挖基础及其施工方法，属于20千伏及以下配电网架空线路电力设备基础技术领域；包括：确定钢管杆的基础位置及掏挖基础参数；钢管杆定位及复测分坑；根据掏挖基础参数进行基础土方开挖及掏挖部分扩径；进行基础坑底操平后基础垫层浇筑；在基础掏挖内部设置主钢筋、箍筋并绑扎成钢筋笼，预先完成主筋与地脚螺栓的连接；进行钢管杆基础混凝土浇筑；地脚螺栓及法兰盘预埋；基础顶抹面及压光；待钢管杆组立完成后，进行基础保护帽浇筑及杆塔接地制作及安装。本发明减少土石方开挖、余土外运的运输费用，基础浇筑中支模、拆模、回填部分可省略，混凝土量相对适中；施工安全风险好控制，环境污染低，工期短，造价低。
