Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] A beam-slab combined foundation suitable for transmission line engineering of the present invention, such as figure 1 with figure 2 As shown, it includes a bottom support layer, a beam frame, and a column 1. The bottom support layer includes a plurality of parallel slats 2. The slats 2 are elongated rectangular plates with a rectangular cross-section and are made of prefabricated concrete. Boards play a role in supporting the entire foundation. The number of slats 2 can be 5, 6 and 7, etc., determined according to calculations, and the present invention does not limit the number of slats 2 . The distance between two adjacent slats 2 is determined according to the calculation and construction requirements, the distance between two adjacent slats 2 can be equal, that is, the slats 2 are evenly arranged, so that the stress of each slat 2 is more u...

Abstract

The invention discloses a beam-plate combined type foundation suitable for power transmission line engineering. The beam-plate combined type foundation comprises a bottom supporting layer, a cross beam frame and a stand column; the bottom supporting layer comprises a plurality of plate strips which are parallel to one another; the cross beam frame comprises a plurality of cross beam layers; each cross beam layer comprises a plurality of cross beams which are parallel to one another; the cross beams of every two adjacent cross beam layers are perpendicular to one another and are detachably connected; the cross beams of the bottommost cross beam layer are perpendicular to the corresponding plate strips and are detachably connected to the corresponding plate strips; and the stand column is detachably connected to the uppermost cross beam layer. The beam-plate combined type foundation has the advantages of being easy to process and produce and easy to install on site, and the universalityof structural members is high. The invention further discloses a construction method. The construction method comprises the steps of excavating a foundation pit, leveling the foundation pit, hoistingthe foundation, and carrying out foundation pit backfilling. The construction method has the advantages that the construction efficiency is high, and the construction quality is good.

Description

technical field [0001] The invention relates to the field of electric power engineering equipment, in particular to a beam-slab combined foundation suitable for power transmission line engineering and a construction method thereof. Background technique [0002] In order to further enhance the construction capacity of smart grid projects, focus on promoting the transformation of line construction methods, strengthen line design, equipment, and construction innovation, carry out the research and application of mechanized construction in the whole process of transmission lines, and realize the transformation from labor-intensive to equipment-intensive and technology-intensive .
