Is the second embedding of Guanglianda an explicit match or an implicit match?

In building engineering, the second pre-embedding is to embed the pipes, cables, interface boxes and other equipment into the concrete in advance before the concrete structure is poured, so as to facilitate the subsequent wiring installation and wiring operation. Secondary embedding is usually divided into two ways: public matching and hidden matching. Exposed distribution refers to the exposure of pipelines and other equipment on concrete surfaces, such as walls or ground, so as to facilitate the subsequent construction personnel to carry out wiring operations. Concealed installation means that pipelines and other equipment are buried inside the concrete, flush with the concrete surface and not exposed. In contrast, concealed installation is more beautiful, safe and stable, which can better protect pipelines and other equipment from external factors. Therefore, for the second embedding scheme of Guanglianda, it is suggested to adopt the hidden matching method.

Dark matching can better protect the stability and safety of pipelines and other equipment. Of course, in the specific implementation process, it is necessary to take into account the needs of specific projects and construction conditions, and carry out reasonable scheme design and safety measures.
