Embodiment Construction

[0030] A construction method for a high-voltage tower foundation, characterized in that it comprises the following steps:

[0031] a sub-pit:

[0032] According to the construction drawings, find out the size of the sub-pit for sub-pit operation, and set up auxiliary piles to facilitate the verification of the central pile;

[0033] b. Earthwork excavation:

[0034] Excavate stepped foundation pits for solid soil and powdery loess, control the width of the bottom plate of the foundation pit, and carry out construction in strict accordance with the construction drawings for the depth of the foundation pit; for over-excavation, the over-excavation part should be paved with stone grouting; for high groundwater levels The foundation pit shall be equipped with pumping equipment to pump out the accumulated water in the pit during construction, and the slope of the pit wall shall be increased;

[0035] During the excavation of the foundation pit, the position and shape of the found...

Abstract

The invention discloses a high-voltage pole tower foundation construction method which is characterized by comprising the following steps: dividing pits, performing earth rock excavation, binding with reinforcing steel bars, constructing foundation formworks, mounting vertical column mold plates, mounting foundation bolts, measuring overall foundation torsion, and casting foundation concrete. As the foundation construction is performed through the steps, vertical columns are effectively prevented from sinking down, and the alignment of the foundation bolts is ensured.

Description

technical field [0001] The design relates to a construction method for a high-voltage tower foundation, which belongs to the field of electric power technology. Background technique [0002] In the foundation construction of the high-voltage pole tower, because the foundation pit of the high-pressure pole tower is a single pit, and the weight of the anchor bolts is large, when the foundation construction is carried out by the traditional method, the column sinks seriously, and the anchor bolts are difficult to align. Therefore, it is necessary to compile new construction methods to guide construction. Contents of the invention [0003] According to the above requirements, the purpose of this design is to provide a construction method for high-pressure tower foundations to ensure the alignment of anchor bolts. . [0004] In order to achieve the above purpose, this design is realized through the following technical means: [0005] A construction method for a high-voltage ...
