Embodiment Construction
[0046] Examples see figure 1 As shown, a well-shaped prefabricated concrete tower foundation includes a foundation body arranged on the foundation and bearing the bottom of the tower column. The foundation body is connected by prefabricated concrete components, including a core block column 1 and a well-shaped beam 2 and base plate 3.
[0047] The cross-section of the core block column 1 described in this embodiment is a regular quadrilateral, and the corner edge positions of the side end faces around the core block column are connected with a well-shaped beam 2 perpendicular to the side end face, and each side end face is provided with two A well-shaped beam 2, the axis of the well-shaped beam 2 connected to the side end face of the opposite side is aligned and coaxial. The side length of the regular quadrilateral is not less than twice the sum of the width of the well-shaped beam 2 and the diameter at the bottom of the tower column, so as to ensure the bearing capacity of t...

The invention discloses a prefabricated concrete tower column foundation in the shape like the Chinese character 'jing' and a construction method thereof. The tower column foundation comprises a main foundation body; the main foundation body comprises a core block column, beams in the shape like the Chinese character 'jing' and foundation bottom slabs; each beam in the shape like the Chinese character 'jing' perpendicular to the corresponding side end surface is connected to the positions of the corner edges of the side end surface on the periphery of the core block column, each side end surface is provided with two beams in the shape like the Chinese character 'jing', and the axes of the beams which are in the shape like the Chinese character 'jing' and connected to the side end surfaces on the opposite sides are aligned and coaxial; the two beams in the shape like the Chinese character 'jing' with the aligned and coaxial axes and the core block column clamped between the two beams are integrally connected through a prestressing tendon penetrating through the beams and the core block column; the position between the side end surfaces of the adjacent beams in the shape like the Chinese character 'jing' is fully connected with the horizontal foundation bottom slab, and all the foundation bottom slabs are located on the same elevation. The prefabricated concrete tower column foundation is a high tower column structure foundation capable of being produced in a prefabricated and industrial mode, the construction period of various tower column foundations can be substantially shortened, the weight of prefabricated members of the prefabricated concrete tower column foundation is decreased, and the prefabrication cost, transport cost and lifting cost of the whole engineer are reduced.
Description
technical field [0001] The invention belongs to the field of prefabricated structures, in particular to a well-shaped prefabricated concrete tower foundation and a construction method thereof. Background technique [0002] The foundation of towering towers has the characteristics of bearing less axial pressure and greater bending moment. At present, most of the foundations of wind turbine towers, communication signal towers and transmission line towers are in the form of cast-in-place foundations. [0003] Under such a special load, the tower foundation will encounter the following problems during the construction process: [0004] 1. When using the form of cast-in-place foundation, the construction process of cast-in-place foundation requires a series of processes such as foundation pit excavation, binding steel bars, pouring concrete, and concrete curing, and these three processes in the construction process occupy the entire foundation construction cycle More than 80% of...
