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

Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] Embodiments of the present invention: when carrying out basement base plate and side wall construction of underground building, adopt the present invention to make its post-pouring tape, post-pouring tape structure of the present invention is as follows figure 1 As shown, during production, the pit floor cushion 1 of the basement is produced according to the existing method, and after the construction of the pit floor cushion 1 of the basement is completed, a layer of waterproof coiled material is fully spread on the pit floor cushion 1 2. The waterproof membrane 2 can directly use the finished synthetic polymer (polyvinyl chloride) waterproof membrane sold in the existing market, and the thickness of the finished synthetic polymer (polyvinyl chloride) waterproof membrane 2 is ≥1.2mm, Its tensile strength is 2.0-4.5MPa, its elongation a...

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...
