    Construction process and method

    1、 Construction method

    1. The project adopts the method of hanging without scaffold for construction.

    2. The outside of chimney is constructed by hanging basket, and the size of hanging basket is made according to the inner diameter of chimney outlet.

    3. Triangle support is installed at the top of chimney, which is made of Φ 8 steel pipe. The support is supported at the top of chimney, and the fulcrum is connected with the channel steel transverse to the top opening.

    4. The middle hanging pulley of the channel steel is used to lift the material, and the suspension point of the lifting material is separated from the suspension point of the lifting basket.

    5. There are two channel steels at the top, one of which is used as the suspension point of lifting materials, and the other is used as the suspension point of lifting basket.

    2、 Construction process

    1. The dust and attachments on the outer wall of chimney must be cleaned with high-pressure water gun,

    2. External wall painting of chimney

    The selected raw materials, design requirements and consistency of construction mortar shall be trial mixed in advance. Slow speed mortar mixer can be used on site, and the proportion and dosage of each component must be strictly controlled.

    Sand should be coarse sand. When the thickness of repair layer is less than 1cm, the sand should be screened by 5mm; when the thickness of repair layer is greater than 1cm, medium coarse river sand should be used, with fineness modulus of 2.5 ~ 3.1. First, add powder and sand to the weighed cement and mix it evenly, slowly and fully. Generally, the mixing time is 3min. The prepared mortar should be used within 45 ~ 60min. If the mortar is not used in time and the mortar is dry and hard, it can not be mixed with water again, and it should be discarded.

    The average thickness of plastering mortar on the outer wall of chimney is about 15mm.

    3. Surface repair treatment

    In order to improve the adhesion of mortar, if there is any attachment on the outer surface of chimney, the electric grinding wheel must be used to polish the surface, and the cement mortar should be used to fill the surface, and the cracks should be filled up.  

    5. Beautification of chimney outer wall

    After the external wall of the chimney is painted and dried naturally, we paint and beautify the outer wall of the chimney.

    (1) The outside of chimney is painted with "red and white" pattern color mark paint.
