Pre-embedding of hydropower projects refers to slotting in the wall and ground to make water pipes and wires into concealed projects. Including PVC threading pipe, 86-type switch socket cassette, inspection port, PVC pipe of wall-mounted TV set, etc., all need to be embedded. The specific process is as follows:
1. Reserve and embed
All professionals conduct internal joint review of drawings to familiarize themselves with the technical requirements of each profession. Water and electricity embedment shall be carried out at the same time as the main body construction, and the person in charge shall cooperate with the civil construction to ensure that the position, model and quantity of the embedded casing are prepared correctly, and the installation is firm and reliable. It is strictly forbidden to dig holes in the wall afterwards.
threading casing equipment closely cooperates with civil construction. The pipelines in beams, columns and floors shall be bound with steel bars synchronously, and the pipelines in walls shall be buried during masonry, and all concealed works shall be recorded in time. Strengthen cooperation and cooperation with other professional types of work and other safety construction, and make technical disclosure to each other to prevent disruption.
2. Installation
Installation works are interspersed with civil interior decoration, and equipment installation shall be carried out before civil plastering as far as possible, so as not to affect the quality of decoration works. During the construction at this stage, fully prepare the labor and materials, closely cooperate with the civil construction, and strengthen the protection of civil finished products, so that the whole construction process can be carried out in an orderly manner.
