Problems solved by technology

[0002] For areas with severe water and soil erosion, the geological moisture is insufficient, and it has strong shear and overturning resistance, but it consumes a lot of materials, and the workload in the excavation process of the foundation pit is relatively large, and it is easy to cause damage to the water and soil environment. Larger damage, at the same time, because the soil quality of the excavated foundation pit is not suitable for backfilling requirements, it is necessary to transport plain soil

Embodiment Construction

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

[0024] Meanwhile, since what is described below are only some embodiments, the embodiments in the present application and the features in the embodiments can be combined with each other under the condition of no conflict.

[0025] A foundation construction method for a high-voltage pole tower, the steps of which include construction preparation, foundation pit excavation, binding steel bars and formwork support, pouring concrete, demoulding, maintenance, and cleaning site quality inspection. The foundation of the high-voltage pole tower adopts a rectangular iron tower foundation, The foundation type adopts the foundation type of anchor bolts, and the main steps of excavating the foundation pit include:

[0026] 1) The rectangular foundation is divided into pits, and the positions of the four foundation pits are determined by dividing the pits;

[0027] 2) Excavate a sample hole...

Abstract

The invention provides a foundation construction method of a high-voltage tower and relates to the field of transmission line tower foundation construction. The foundation of the high-voltage tower adopts a rectangular iron tower foundation, and the foundation type adopts a foundation bolt foundation type. Foundation pit excavation mainly comprises the following steps that a rectangular foundationis divided into pits, and the positions of the four foundation pits are determined according to the divided pits; sample holes are dug according to the excavation sizes of the foundation pits; the sizes are measured again after the sample holes are excavated, and excavation continues after the design requirement are met; the sizes of the pit walls are controlled in the excavation process of the foundation pits, and the pit walls are guaranteed to be vertical; base plates are built; stand columns are built on the base plates; foundation bolts of thet rectangular foundation are aligned; the sizes of all parts are checked; and self-compacting concrete is adopted in the concrete pouring process. According to the foundation construction method, the self-compacting concrete is adopted, the mutual relation between the characteristics of the self-compacting concrete can be balanced, the compactness is improved, cracks can be effectively prevented from being generated, the structure durabilityis improved, and damage to soil caused by repeated construction is avoided.

Description

technical field [0001] The invention provides a foundation construction method for a high-voltage pole tower, and relates to the field of transmission line pole tower foundation construction. Background technique [0002] For areas with serious water and soil erosion, the geological moisture is insufficient, and it has strong shear and overturning resistance, but it consumes a lot of materials, and the workload in the excavation process of the foundation pit is relatively large, and it is easy to cause damage to the water and soil environment. Larger damage, at the same time, because the soil quality of the excavation of the foundation pit is not suitable for the requirements of backfilling, the plain soil needs to be transported. On this basis, the operation of compact transmission lines makes the force of the tower foundation more and more large, and the requirements for the tower foundation are getting higher and higher. Contents of the invention [0003] In order to s...
