An assembled height-adjustable outdoor gis rear embedded part and its construction method

Abstract

The invention discloses an assembly type height-adjustable outdoor GIS postposition embedded part and a construction method of the assembly type height-adjustable outdoor GIS postposition embedded part. The postposition embedded part comprises an anchor bolt sleeve arranged inside a foundation pre-drilled hole and self-locking anchor bolts penetrating through an embedded part steel board, a supporting nut connected with the self-locking anchor bolts is arranged between the embedded part steel board and a foundation facility, the upper face of the embedded part steel board is provided with a conical head nut connected with the self-locking anchor bolts, the upper face of the conical head nut is provided with a fastener used in cooperation with a nut installation device, and the fastener is used for adjusting the height of the embedded part steel board and fixing the embedded part steel board at the position between the supporting nut and the conical head nut. Firstly, the number of the anchor bolts, the center distance of the anchor bolts and the anchoring length of the anchor bolts are calculated, and the anchor bolts are selected; a GIS concrete foundation and the embedded part steel board are drilled according to the positions of the anchor bolts, the plastic anchor bolt sleeve is arranged inside the pre-drilled hole of the foundation facility in advance, and the anchor bolts and the embedded part steel board are spliced, anchored and leveled. The assembly type height-adjustable outdoor GIS postposition embedded part and the construction method of the assembly type height-adjustable outdoor GIS postposition embedded part have the advantage of solving the problem that the requirements for flatness, rigidity and precision of embedment of the embedded part are high.

Description

technical field [0001] The invention relates to the field of power generation and transformation, in particular to an assembled height-adjustable outdoor GIS rear embedded part and a construction method thereof. Background technique [0002] During the construction of the traditional outdoor GIS (gas insulated fully enclosed combined electrical appliances) equipment foundation, the equipment embedded parts are poured into the foundation together with the GIS foundation construction. Therefore, the design and construction of the equipment embedded parts must wait until the equipment manufacturer submits the embedded parts information If the manufacturer modifies the equipment data in the later stage, it will affect the design and construction progress. In addition, the equipment is usually installed in stages according to the demand, but the long-term embedded parts are usually buried in the first phase of the project, which may lead to the unsatisfactory embedded parts in the...

AI Technical Summary

Problems solved by technology

[0004] 1. Since the embedded parts have been designed or constructed, the manufacturer’s equipment data has changed, and the embedded parts and outdoor GIS foundation embedded parts must be re-arranged, resulting in rework of the design or construction, which is time-consuming and laborious, and affects the construction period

[0005] 2. Embedded parts are buried incorrectly or missed during design or construction

[0006] 3. The flatness, rigidity and precision requirements of embedded parts are high, and the traditional construction methods cannot meet the requirements

[0007] 4. The construction period is tight, and the curing time of cast-in-place concrete is insufficient

However, the following problems may occur in the vision project: due to technological progress, the original equipment has been eliminated, or due to different manufacturers, the embedded parts in the early stage do not meet the requirements of the new equipment, and the embedded parts must be re-arranged
