An electrical pre-embedded pipe through concrete foundation positioning device

Abstract

The invention proposes a positioning device for electric pre-embedded pipes passing through concrete foundations. The positioning device includes a positioning plate and positioning bolts. The positioning bolts are located in the bolt through holes opened around the positioning plate, and there are pre-embedded pipe through holes on the positioning plate. And there is a rubber ferrule on the through hole of the pre-embedded pipe. This positioning device ensures the positioning accuracy of the pre-embedded pipe and completely avoids the common phenomenon of honeycomb pitting when the pre-embedded pipe pierces through the concrete foundation. At the same time, the pre-embedded pipe is nested The rubber ferrule avoids the displacement of pre-embedded pipe fittings and grout leakage caused by vibration during concrete construction.

Description

technical field

[0001] The invention relates to a positioning device, in particular to a positioning device for electric pre-embedded pipes penetrating concrete foundations. Background technique

[0002] In the construction process of the existing substation, according to the engineering design requirements, a large number of electrical pre-embedded pipes need to be buried on the concrete foundation of the substation, and most of the pre-embedded pipes are of multi-layer structure. In the existing substation concrete foundation construction, the pre-embedded pipes are usually positioned according to the design requirements of the drawings, by opening the pre-embedded pipe through-holes on the wooden formwork. Due to the problem of wooden materials, when opening the pre-embedded pipe through-holes, The accuracy of the through-hole of the embedded pipe cannot be guaranteed, resulting in the occurrence of problems such as insufficient concrete plugging in the later stage.
