Description
技术领域technical field
本实用新型涉及一种电力工程输配电基础，具体地说涉及一种电杆预制基础。The utility model relates to a power transmission and distribution foundation for electric power engineering, in particular to a prefabricated foundation for electric poles.
背景技术Background technique
电力工程输配电杆基础目前广泛使用的是大开挖混凝土浇筑基础，施工周期长，一般大于30天，占地面积大，开挖量多，从南方冰灾倒杆重建的过程来看，大开挖基础严重影响抢修进度，所以大都利用原基础，但是拆除旧杆的工作量较大。The foundation of power transmission and distribution poles in electric power engineering is currently widely used as a large excavation concrete pouring foundation. The construction period is long, generally more than 30 days, the area is large, and the amount of excavation is large. From the perspective of the reconstruction process of the southern ice disaster, The large-scale excavation of the foundation seriously affects the progress of emergency repairs, so most of the original foundations are used, but the workload of removing the old poles is relatively large.
发明内容Contents of the invention
本实用新型的目的就在于克服上述不足提供一种电杆预制基础，解决了电杆基础施工周期长的技术问题。The purpose of the utility model is to overcome the above disadvantages and provide a prefabricated pole foundation, which solves the technical problem of long construction period of the pole foundation.
本实用新型的技术方案如下：The technical scheme of the utility model is as follows:
一种电杆预制基础，包括基础立柱，基础立柱顶端设置预埋钢圈，预埋钢圈上焊接地脚螺栓，基础立柱上至少设置一个承力盘。The utility model relates to a prefabricated electric pole foundation, which includes a foundation column, a pre-embedded steel ring is arranged on the top of the foundation column, anchor bolts are welded on the pre-embedded steel ring, and at least one bearing plate is arranged on the foundation column.
上述电杆预制基础，所述承力盘是伞状。For the prefabricated foundation of the above-mentioned electric pole, the bearing plate is in the shape of an umbrella.
上述电杆预制基础，所述承力盘是三个。For the prefabricated foundation of the above electric pole, there are three bearing plates.
上述电杆预制基础，所述基础立柱是空心基础立柱。For the prefabricated foundation of the electric pole, the foundation column is a hollow foundation column.
本实用新型采用上述结构，本实用新型有以下优点：现场施工方法简单、无需进行繁琐的施工准备、材料准备。与原现场施工工艺相比免去了现场浇筑、养护、材料试品试验等技术过程，由于成品是预制的，因此与在施工现场现浇混凝土、钢筋尺寸现场固定焊接、模板现场安装相比可以不受自然、季节、气候的影响和干扰，尤其是在冬季和夏季；改善了因温度浇筑混凝土带来的各种材料膨胀系数的变化。原现场浇筑的混凝土时间需要养护夏季20天以上，冬季28天以上。加上模板支架安装拆卸和运输等需要增加成本和发生各种费用。本实用新型直接运到施工现场，开挖土后将本实用新型埋入坑中，回填土方，工期大约2天。根据不同的施工需要本实用新型可以做成不同的规格。本实用新型使用于各种土壤、应用范围广，造价低，工期短，大大节约了工程成本。同时也有利于输电线路的事故抢修和恢复重建。The utility model adopts the above structure, and the utility model has the following advantages: the on-site construction method is simple, and there is no need for complicated construction preparations and material preparations. Compared with the original on-site construction process, technical processes such as on-site pouring, maintenance, and material sample testing are eliminated. Since the finished product is prefabricated, it can be compared with cast-in-place concrete at the construction site, on-site fixed welding of steel bar size, and on-site formwork installation. It is not affected and disturbed by nature, seasons, and climate, especially in winter and summer; it improves the changes in the expansion coefficient of various materials caused by pouring concrete due to temperature. The original concrete poured on site needs to be cured for more than 20 days in summer and more than 28 days in winter. In addition, the installation, disassembly and transportation of formwork brackets need to increase costs and various expenses occur. The utility model is directly transported to the construction site, and the utility model is buried in the pit after the soil is excavated, and the earthwork is backfilled, and the construction period is about 2 days. The utility model can be made into different specifications according to different construction needs. The utility model is applicable to various soils, has wide application range, low cost and short construction period, and greatly saves engineering cost. At the same time, it is also conducive to the emergency repair and restoration of transmission lines.
