Prefabricated assembly type independent foundation
The invention discloses an assembling method for an independent foundation of a main control building of a modularized transformer substation. Components used in the method comprise a left shear groove module (101), a shear key module (102), a right shear groove module (103) and a prestress fastening steel bar (104). The left shear groove module (101) and the right shear groove module (103) are connected with the shear key module (102) in an inserted mode respectively and then transversely fastened through the prestress fastening steel bar (104) to form a whole, the concrete tensile stress caused by loads is reduced by applying prestress, and therefore the tensile stress of an independent foundation component is controlled within a small range and even in a pressed state, and the construction quality of the independent foundation component is improved. The appearance and development of concrete cracks are delayed, so that the anti-cracking performance and rigidity of the component are improved. Compared with the prior art, the modular substation main control building independent foundation assembly method is simple in structure and easy to prefabricate; the installation process is time-saving and labor-saving, has no special technical requirements, is very suitable for outdoor substation infrastructure construction, can adapt to different natural environments, and effectively shortens the construction period.
本发明公开了一种模块化变电站主控楼独立基础装配方法，所用构件有左剪力槽模块(101)、剪力键模块(102)、右剪力槽模块(103)、预应力紧固钢棒(104)。左剪力槽模块(101)、右剪力槽模块(103)分别与剪力键模块(102)插接，然后用预应力紧固钢棒(104)进行横向紧固，使之形成一个整体，通过施加预应力来减小荷载引起的混凝土拉应力，从而使独立基础构件的拉应力控制在较小范围，甚至处于受压状态，以推迟混凝土裂缝的出现和开展，从而提高构件的抗裂性能和刚度。与现有技术相比，本发明的一种模块化变电站主控楼独立基础装配方法，构造简单、容易预制；安装过程省时省力，无特殊技术要求，十分适用于户外变电站基础建设，能够适应不同自然环境，有效缩短施工工期。
