Beautify communication tower installation scheme
Single external pole vertical hoisting construction of single pipe beautification communication tower is a construction method developed by professional construction personnel and technicians on the basis of years of practice of each construction and installation unit engaged in the installation of soil method and the construction of high-altitude chimney, maintenance and anti-corrosion. This method requires high quality of construction equipment, and must be operated strictly according to hoisting operation rules.
1. Construction technical measures
The installation of single beautification communication tower adopts the vertical type of single external pole. According to different topography and landform, follow the following steps:
First observe the terrain and determine the correct position of 5-6 wind cables. Then check the beautification of communication tower foundation and foundation bolt embedded is correct, check the beautification of communication tower body material quality whether there are defects. Determine the center point of the tower body and the embedded direction of the main wind cable. Generally, seamless steel tube material with the specification of 108mm 6mm 7500mm shall be used as the auxiliary grillage, and seamless steel tube material with the specification of no less than 159mm 8mm and the total length of 16 ~ 17m shall be used as the main grillage. 5 ~ 6 steel wire ropes with length of 1.2cm and 100m at the bottom of the mast shall be used as wind cables, and spiral ground anchor piles (above 5t) made by the homemade or the manufacturer shall be used to bear the pulling force of wind cables. Use 2t hand hoist crane to control the lifting of the wind rope. Tighten the wind rope after the derrick is in place. The anchor and hoist are fastened with steel wire rope with a diameter of more than 12mm, and the reasonable position of the hoist is correctly selected.
When hoisting the tower body of the first section, first fix the upper and lower ends of the first tower body with a 10mm 200mm steel plate hoop, generally 2.8 ~ 3m away from the top of the tower section. After hoisting, reset the installation, tighten it with bolts, and confirm and correct the slope. When hoisting the second tower body, hoist the derrick bar with a hoist at least 0.5-1t first. The hoisting point is set in the screw hole of the inner flange of the upper part of the first tower body. The steel wire rope and S hook are used for double safety connection. When the derrick is lifted to the upper part of the tower body in the first section, when it is fixed with the hoop, the hoisting hoist point of the crane must be separated from the derrick point, and a double line is adopted. It is forbidden to use one hoisting point.
The lifting tower is separated from the heavy lifting bar and is carried out by two lines. If it is operated by a hoist, the steel wire rope on the hoist must be rewound after each lifting of the derrick and the lifting tower body to work separately. It is forbidden to use single movable pulley, but must use two or three sliding pulley sets to lift and lift the tower body, no matter it is the lifting bar or the lifting tower body.
In the lifting of the second section of the main mast, also must be in the upper mouth of the barrel, with wire rope to do safety insurance for the mast. Wire rope is used to hold the tail at the bottom of the derrick, and a certain pulley is set at the bottom of the tower body, so as to ensure the safety lifting of the derrick in place along the directional track. Cycle operation in the same way to beautify the communication tower to complete the overall installation.
When installing the platform, install the upper and lower platforms and railings by yourself according to the experience of different construction units. There is no emphasis on uniform procedures, but the principles of safety and convenience must be followed.
After the whole tower body is installed, the construction team shall carry out the post-installation standard inspection from top to bottom, including tower body cleaning, repainting, bolt fastening inspection, inner grounding of the cylinder, laying of lighting cables, etc., and check the perpendicularity of the cylinder body.
