How do we correct the verticality of the street lamp pole?

How do we correct the verticality of the street lamp pole? We can take a look at the following.

1. First look at the bottom, that is, the part with flange, to see if it is straight. Is there a simple way to measure verticality?

The operation method is to tie the heavy object with a thin nylon rope, and hold the top of the nylon rope with your hand about 10 meters away from the street lamp pole, so that the gravity will naturally drop, and then use an eye to vertically pass through the line between the nylon rope and the bottom of the street lamp pole, which is 20 cm away from the eye.

If this method can be used in the east, west, north and south directions, the perpendicularity of the bottom is OK.

If the bottom of the street lamp pole is not parallel to the nylon rope, it needs to be adjusted in time. Otherwise, the part inserted above is not vertical, and even the higher the higher the slope. It can be said that the lower beam is not straight and the upper beam is crooked.

2. Check whether the insert is in place. Generally, whether it is street lamp pole, communication tower or beautification tower, all steel poles that need to be inserted will have a theoretical insertion depth during design.

If the actual insertion depth differs greatly from the theoretical insertion depth by more than 20cm, the installation may be incorrect. The vertical movement can be ensured only when the depth is confirmed to be sufficient.

3. If it is confirmed that the bottom segment is vertical, other segments are inserted in place. If it is still not straight, there is only one possibility, that is, the insertion direction is wrong.

Road signs, monitoring poles and their main components shall be durable structures made of materials capable of withstanding certain mechanical, electrical and thermal stresses. Materials and electrical components shall be moisture-proof, self explosive, fire-resistant or flame retardant products. The installation requirements of street lamp poles are as follows:

① The reinforcement cage of the foundation shall be temporarily fixed, and the foundation roof plane of the reinforcement pet shall be horizontal, that is, the level meter shall be used to measure the two vertical directions of the foundation roof, and the bubbles shall be centered; The foundation concrete of the embedded parts of the traffic monitoring rod (road monitoring rod) must be dense, and the concrete must not be free.

②During construction, the embedded pipe orifice shall be sealed with plastic paper or other materials in advance to prevent concrete from leaking into the embedded pipe during concrete pouring and blocking the embedded pipe; After the foundation is built. The foundation surface must be 5mm~10mm higher than the ground plane; The concrete must be cured for a period of time to ensure that the concrete can reach a certain installation strength.

③Each metal pole (traffic monitoring pole, road monitoring pole) must be grounded, and its grounding resistance is less than 4 ohms; The specific data of each pole (traffic monitoring pole, road monitoring pole) shall be subject to the needs of on-site construction.

Before design, try to arrange the layout and fill the limited space as much as possible. In the early stage of design, in order to check the standard rationality of the traffic light pole design, the detailed layout of the traffic light pole can be made on the computer (the normal construction drawings basically provide specific patterns and text sizes, which can be omitted). However, it is a good design method to conduct preliminary test design demonstration for the design of temporary road post bridge deck, which not only ensures the standardization and rationality of road post design, but also saves manpower and material resources and eliminates rework caused by unreasonable design.

Due to the large size of the traffic sign board, the high-strength reflective film is fragile relative to the project reflective film, which is difficult to form the film, and bubbles will appear. For these reasons, effective measures must be taken, such as strictly controlling the environmental sanitation of the processing workshop to prevent excessive humidity in the air; The humidity of the front aluminum foil must not be too low. Good humidity control is an important condition for the durability of highway street lamp poles. For the bubbles that have been caused, the treatment methods such as suction, blowing and scalding, and repair are adopted for separation, and the effect is ideal.
