What are the requirements for the construction of music fountain?

In the design and construction of music fountain, attention should be paid to the installation of lights, whether all fountains and background music electrical equipment meet the national standards, waterproof cables must be used for the lighted wires, and the joints should be waterproof according to the specified technology. In addition, the design drawings must be fully understood and mastered, and the budget of the whole project should be planned before the construction of the music fountain. What are the specific matters needing attention in the design and construction of music fountain, and what are the requirements for the construction of music fountain? Come and read the article with me! 1. What are the precautions in the design and construction of the music fountain?

1. Before pipeline installation, the lumen should be cleaned, the main pipe should be horizontal, the riser should be vertical and the main pipe should be fixed. Before the pipeline is coated with antirust paint, rust and welding slag should be removed, and the water pump should be installed firmly and stably.

2. Installation of lamps: positioning of lamps, manufacture and installation of lamp clips, and fixing of lamps.

3. Cable laying and waterproof connection: Cables for pumps and lamps should be routed according to regulations, and the principle is to reduce underwater joints. The cable should be connected (the heat shrinkable tube is waterproof), the cable should be inserted into the cable tube in the center, and the cable should be sealed with glue near the bell mouth. Pumps and lamp lines shall be numbered according to the drawings. Cables can be laid along the cable trench to the control room and enter the power distribution cabinet through the cable tray.

(1) Before installation, the performance of water pump, valve and lighting lamp must be tested to ensure the insulation of water pump is intact. The resistance should be measured by shaking table, and its resistance should be greater than 50 megohms.

(2) The wires of lighting lamps and lanterns must be waterproof cables, and the joints should be waterproof according to the specified process, and the connection must be firm.

(3) Test the insulation resistance of each circuit with a megger, and the insulation resistance should be above 5 megohms.

(4) Check whether the water pump and the grounding wire of lamps and lanterns are connected.

4. Installation of power distribution control equipment: Control and power distribution equipment are placed in the control room according to the drawings, and load equipment is connected to the corresponding terminals of power distribution equipment according to the cable number.

5. All fountain _ background music electrical equipment (including: water pump, lamps, electric control cabinet, computer, controller, frequency converter, transformer _ water curtain generator _ laser projector and other metal casings) shall be equipotential grounded, and the equipotential grounding shall meet the national standard (Jian [1998] No.65438 +0 equipotential connection installation).

(1) General equipotential connection: A general equipotential connection terminal board shall be installed in the incoming electric control cabinet to connect the following conductive parts with each other. —— PE(PEN) bus of incoming electric control cabinet —— control room grounding electrode.

(2) A local equipotential connection plate is set in the fountain pool to connect the following conductive parts with each other. -Metal casings of water pumps and lighting lamps-Metal pipes for water supply, drainage and overflow-Main steel bars and metal structures of the building, including metal supports for the pool grille.

(3) All fountain _ background music electrical equipment (including: electric control cabinet, computer, controller, frequency converter, transformer _ water curtain generator _ laser projector and other metal casings) shall have auxiliary equipotential connection.

(4) The general equipotential connection board (grounding bar) and the local equipotential terminal board are made of copper plates. The total equipotential bonding line is not less than 0.5X incoming line, and the PE section of incoming line. The section of the auxiliary equipotential bonding wire is not less than 4.0mm2 copper conductor or round steel with a diameter of 8mm or flat steel with a diameter of 20*4mm.

(5) The connection between the connecting conductors in the equipotential bonding line can be welded or bolted. The lap length of flat steel is not less than 2 times its width, and it is welded on three sides, and the lap length of round steel is not less than 6 times its width, and it is welded on both sides.

Second, what are the main points of the construction of music fountain?

Music fountain can provide people with high ornamental value. In order to achieve the expected effect in the later period, the construction requirements of music fountain should not be sloppy, which is introduced from the following three points.

1, the design drawings must be fully understood and mastered, and the analysis must be clear. According to the design drawings, make a site survey to find out whether the geographical location allows the construction of a music fountain.

2. Before the construction of the music fountain, the budget planning of the whole project, including the construction company and contract, should be done well.

3, music fountain construction, it is very necessary to make arrangements, but also to choose the type of materials used in music fountain construction, to ensure the quality and safety of engineering materials, at the same time, there should be reasonable procedures, keep records of related materials, arrange construction time reasonably, and divide labor reasonably.

The preparation work before the construction of the musical fountain is very important. Only by making reasonable planning in advance and ensuring the orderly and reasonable construction process can the whole project be completed perfectly.
