How to install the monitoring pole?

The steel cage of the foundation should be temporarily fixed, and at the same time ensure that the plane of the foundation roof of the steel cage is horizontal, that is, use a horizontal NEW ruler to measure in two vertical directions of the foundation roof, and observe that the bubbles must be centered; the monitoring poles are pre-embedded The concrete for the foundation must be poured densely, and no empty drums are allowed in the concrete; the length of the arm required for installing the pole shall be subject to the actual site conditions. Foundation construction vertical pole foundation to fix the camera pole; Purpose: Basic structure, size: Basic model: Determined by the camera pole model to be fixed; Production location: Make the foundation at the location of the camera pole marked on the "Equipment Layout Plan"; Production requirements : It should comply with the relevant provisions of the current national standard "Cable Line Construction and Acceptance Specifications for Electrical Installation Engineering"; there should be a threading pipe between the foundation and the manhole, and iron wire should be placed; the steel bars on the foundation steel plate are tapped according to the M20 standard and equipped with galvanized screws Two, one each flat washer and spring washer. Materials: 8mm steel plate, 20mm steel bar, C25 concrete, gravel, 2.5-inch PVC elbow pipe; steel pipes are used for concealed pipe laying. PVC pipes are used for open pipe laying. Regular use of grounding body installation: to prevent external voltage from endangering personal safety and damage to equipment, suppressing electrical interference, and ensuring the normal operation of equipment; grounding body structure and size: as shown in the "Grounding Body Structure Schematic"; installation location: connected to "Equipment The floor plan shall indicate the location of the grounding body for installation. Installation requirements: It should comply with the relevant provisions of the current national standard "Cable Line Construction and Acceptance Specifications for Electrical Installation Engineering"; the grounding body should be welded by lap welding, and the length of the lap welding should be 6 times the diameter of the round steel; the bottom of the grounding body installation point should be No pipes or cables pass through; the installation depth of the grounding body is as shown in the "Grounding Body Installation Schematic"; after the grounding body is installed, a grounding megger should be used to measure the grounding resistance, and the grounding resistance is required to be less than 4Q. Note that resistance should not be measured immediately after rain. Material: 2.5 inch steel pipe and 30*5 flat steel.
