Construction method for extra-high voltage direct current transmission tower in alpine region and transmission tower
The invention relates to a construction method for an ultra-high-voltage direct-current transmission tower in an alpine region and the transmission tower. The construction method comprises the following steps that a foundation pit is machined in a to-be-constructed site; building a warm shed for enclosing the foundation pit; determining the raw material ratio of the concrete according to the current environment information and preparing the concrete; the concrete is heated to a preset temperature, and the concrete at the preset temperature is adopted for pouring in the foundation pit; the foundation pit is sealed, steam is injected into the foundation pit, and the preset duration is maintained; the concrete is solidified within the preset duration and forms a stand column foundation of the power transmission tower; a power transmission tower body is built on the stand column foundation. Compared with the prior art, the power transmission tower construction mode is adopted for construction, the concrete setting time can be shortened, the concrete cracking phenomenon can be prevented, the construction difficulty of the direct-current power transmission line in the alpine region is reduced, the construction period is shortened, and meanwhile the construction quality can be guaranteed.
本申请涉及一种用于高寒地区特高压直流输电杆塔的施工方法及输电杆塔，包括如下步骤：在待施工地点加工出基坑；搭设围蔽基坑的暖棚；根据当前环境信息确定混凝土的原材料配比并制备混凝土；将混凝土加热至预设温度，在基坑内采用预设温度的混凝土进行浇筑；将基坑密闭，向基坑内注入蒸汽并维持预设时长；在预设时长内使混凝土凝固并形成输电杆塔的立柱基础；在立柱基础上建设输电杆塔主体。与传统技术相比，采用上述输电杆塔施工方式进行施工，能够加快混凝土的凝固时间，防止混凝土开裂现象的发生，在降低直流输电线路在高寒地区的施工难度、缩短工期的同时，还能够保证施工质量。
