Embodiment Construction
[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0017] 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 adopt 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 selected to be greater than or equal to 1.2mm. Its tensile...

Abstract
The invention discloses a manufacturing method and a structure for a cast strip. According to the method, after construction of a pit baseplate cushion layer (1) of a basement is completed, the pit baseplate cushion layer (1) is fully paved with a layer of waterproof roll (2); then an externally attached type water stop band (5) is pre-embedded in the waterproof roll (2) and in a joint seam between a to-be-prepared main structure (3) and a post-cast strip (4); then the main structure (3) is poured out according to a conventional process; after age of concrete of the main structure (3) reachessix weeks, after chiseling is performed on the concrete and the concrete at the joint seam combining the post-cast strip (4), and then pouring is performed by utilizing shrinkage-compensating concreteto prepare the post-cast strip (4). The manufacturing method for the cast strip not only has the advantages of good waterproof and anti-seepage performance, but also has the advantages of simple structure and convenient construction. The manufacturing method for the cast strip is particularly suitable for usage of a base plate and side wall of the basement of a semi-underground substation rectifier chamber in an electrolytic plant when a foundation geology condition is better and an underground water level is higher.
Description
technical field [0001] The invention relates to a manufacturing method and structure of a pouring tape, which belongs to the technical field of post-casting tape manufacture for buildings. 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 the high grou...
