Manufacturing method and structure of post-poured strip of underground building

Abstract

The invention discloses a manufacturing method and a structure of a post-poured strip of an underground building. After the construction of a basement pit baseplate cushion layer (1) finishes, a layer of waterproof coiled material (2) is laid on the basement pit baseplate cushion layer (1), then an externally-adhered waterstop (5) is pre-embedded on the waterproof coiled material (2) and the joint of main structure (3) to be made and the post-poured strip (4), and the main structure (3) is poured by adopting a conventional process; after the concrete of the main structure (3) has the age of six weeks, the concrete at the joint of the main structure (3) and the post-poured strip (4) is roughened, and then shrinkage-compensating concrete is used to pour to obtain the post-poured strip. The post-poured strip has the advantages of good water and seepage prevention performance, simple structure and convenience for construction. The post-poured strip is particularly suitable for the basement baseplates and side walls of the semi-underground power transforming and rectifying room in an electrolysis workshop when the geological condition of a foundation is good and the underground water level is high.

Description

technical field [0001] The invention relates to a manufacturing method and structure of an underground building post-cast belt, belonging to the technical field of building post-cast belt production. Background technique [0002] Aluminum electrolysis belongs to the metal smelting process. The main raw material is alumina powder to produce aluminum solution. The main power source is direct current, which comes from the 110kV alternating current of the high-voltage power grid. The electrolytic aluminum plants with an annual output of more than 100,000 tons mostly use 4 or more rectifier units for outlet intervals, and the total length of the buildings is more than 60 meters, and they are often semi-basement buildings. Because the equipment in the rectification room is live equipment, and the special important position of the rectification room in the whole electrolytic aluminum plant, and when the rectification room is located in the basement and the unfavorable factors of th...

AI Technical Summary

Problems solved by technology

However, the waterproof treatment of the existing substation rectifier pit post-casting belt is one to two waterproofing, its waterproof ability is weak, and there is a hidden danger of water leakage

Therefore, the manufacturing mode of the existing underground building post-casting belt still cannot meet the needs of use
