How do we correct the verticality of the streetlight pole? What are the installation specifications?
1. First, let's take a look at the bottom, which is the flanged part, to see if it is straight. Is there a simple way to measure if it is vertical? The method is to tie a weight to a thin nylon rope, and hold the top of the nylon rope about 10 meters away from the streetlight pole. The weight will naturally fall due to gravity, and then use one eye to vertically align a line 20 centimeters from your eye to the distance between the nylon rope and the bottom of the streetlight pole. If this method works in all four directions: east, west, north, and south, then the verticality at the bottom is acceptable. If you find that the bottom of the streetlight pole is not parallel to the nylon rope, adjustments need to be made promptly. Otherwise, the upper part will not be vertical and may even tilt more as it goes higher. It can be said that the lower beam is not straight and the upper beam is crooked. 2. Check if the embedded parts are in place. Generally, whether it is a streetlight pole, communication tower, or beautification tower, all steel rods that need to be inserted will have a theoretical insertion depth during design. If the actual insertion depth differs significantly from the theoretical insertion depth by more than 20 centimeters, it may indicate incorrect installation. Only by confirming that the depth is sufficient can we ensure vertical movement. 3. If it is confirmed that the bottom section is vertical and other sections are in place but still not straight, there is only one possibility: the insertion direction is incorrect. Road signs, monitoring poles, and their main components should be durable structures made of materials that can withstand certain mechanical stress, electrical stress, and thermal stress. The materials and electrical components should be moisture-proof, explosion-proof, fire-resistant or flame-retardant products. The installation requirements for streetlight poles are as follows: 1. The foundation's rebar cage should be temporarily fixed, and the surface of the rebar pet's foundation top plate should be level; that is, use a level to measure in two perpendicular directions on the foundation top plate with the bubble centered; the concrete for traffic monitoring poles (road monitoring poles) must be dense, and concrete must not be allowed to segregate. 2. During construction, the embedded pipe openings should be sealed in advance with plastic or other materials to prevent concrete from leaking into embedded pipes during pouring; after laying a good foundation, the surface must be 5mm to 10mm above ground level; concrete must be cured for a period of time to ensure it reaches a certain installation strength. 3. Each metal pole (traffic monitoring pole, road monitoring pole) must be grounded with a grounding resistance of less than 4 ohms; specific data for each upright pole (traffic monitoring pole, road monitoring pole) should be based on site construction needs. Try to layout before design as much as possible to fill limited space effectively. In the early stages of design, in order to verify the rationality of traffic streetlight pole design standards, detailed layout drawings can be made on a computer (normal construction drawings generally provide specific patterns and text sizes; this step can be omitted). However, conducting preliminary experimental design verification for temporary road sign poles on bridge surfaces is a good design method that ensures compliance and rationality in road sign pole design while saving manpower and resources and eliminating rework caused by unreasonable designs. Due to the large size of traffic sign boards and the brittleness of high-strength reflective film compared to engineering reflective film, it is difficult to form films without bubbles appearing. To address these issues, effective measures must be taken such as strictly controlling environmental hygiene in processing workshops to prevent excessive humidity in the air; humidity on front aluminum foil must not be too low; good humidity control is an important condition for ensuring durability of highway streetlight poles. For bubbles that have already formed, methods such as suctioning, blowing hot air, and repairing can be used for separation with ideal results.
