Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: However, since the secondary structure is constructed on the basis of the primary structure, the interface connection force between the old and new concrete drops more seriously, which makes the connection between the secondary structure and the primary structure easy to appear. gaps, resulting in percolation, therefore, there is still room for improvement

Embodiment 1

[0064] refer to figure 1 , is a secondary structure anti-seepage and anti-leakage construction method disclosed by the present invention, comprising the following specific steps:

[0065] S1. According to the requirements of the design drawings, mark the place where the primary structure needs to be constructed for the secondary structure, draw a line with chalk on the surface where the primary structure is about to be connected with the secondary structure, and circle the area where the primary structure is about to be connected with the secondary structure, forming Connection face ID.

[0066] S2. Gouging the surface of the structure at the area circled by the connection surface mark with a pick to form a connection groove, the length of the connection groove is consistent with the length of the area circled by the connection surface mark, and the width of the connection groove is the area circled by the connection surface mark 105% of the width, the depth of the connecting...

Abstract

The invention relates to the technical field of secondary structure construction, in particular to a secondary structure impervious leakproof construction method. The method comprises the following steps that S1, the surface of a primary structure is marked so that the area, to be connected with a secondary structure, of the primary structure can be circled, thereby forming a connecting surface mark; S2, the surface of the primary structure is damaged so that a dented connecting groove can be formed, wherein the connecting groove at least completely covers the area indicated by the connectingsurface mark; S3, a casting template is built according to secondary structure design drawings; S4, concrete slurry is prepared; S5, the concrete slurry is cast; S6, curing with the template is performed; and S7, the casting template is detached after the concrete slurry is solidified, and the secondary structure is formed. The concrete slurry comprises the following components including, by mass,100 parts of Portland cement, 300-350 parts of fine aggregate, 150-200 parts of coarse aggregate, 30-40 parts of talcum powder, 6-8 parts of a concrete expanding agent and 90-110 parts of water. Thesecondary structure impervious leakproof construction method has the effect that leakage is not prone to occurring in the position where the primary structure is connected with the secondary structure.

Description

technical field [0001] The invention relates to the technical field of secondary structure construction, in particular to a secondary structure anti-seepage and anti-leakage construction method. Background technique [0002] At present, with the development of technology, concrete buildings are becoming more and more popular. Buildings made of reinforced concrete have higher stability and faster construction efficiency. The construction process of concrete buildings includes the primary structure (the load-bearing component part of the main structure) and the secondary Structures such as: filling walls, lintels, structural columns, parapets and other non-load-bearing structures. [0003] During the construction of the existing secondary structure, it is usually constructed on the frame of the primary structure by means of blocks or cast-in-place after the primary structure is solidified. The addition of the secondary structure can make the building more functional. , better...
