Technical Field

The invention relates to a construction and installation method of an enclosing wall.

Background

In the construction of transformer substation engineering, the enclosure project is indispensable, and work load is big, and its construction quality, progress will directly influence the whole image of transformer substation engineering. In the construction of a power grid, a transformer substation enclosure is mostly built on site by using a wall body and a dry wall, the construction period is long, the requirement on the construction process is high, the dry wall has the problems of alkali resistance, cracks and the like, particularly in northern areas, the construction period is greatly influenced by climate, and regular maintenance is needed after the construction period is built.

Disclosure of Invention

Aiming at the problems in the prior art, the invention provides a construction and installation method of an enclosing wall, which solves the problem of long construction period in the prior art.

A construction and installation method of an enclosing wall comprises the following steps:

step 1, installing wind-resistant columns of the enclosing wall: the wind-resistant column is hoisted column by a small crane; the wind-resistant column is connected with the foundation in a cup mouth manner, and then the positioning size and the verticality are checked;

step 2, installing the wall boards: the wall boards are lifted by adopting a special clamp and a small crane, and then 4 wall boards of each block are installed in the clamping grooves of the wind-resistant columns of the enclosing wall from bottom to top one by one; after the groove is in place, adjusting and checking the levelness and the verticality of the groove, and then filling the reserved groove with cement mortar in a ratio of 1:3 to be compact; step 3, enclosing wall coping installation: the enclosure wall pressing tops are installed in the sequence of firstly installing the wind-resistant column pressing tops and then installing the wallboard pressing tops; the bottom of the column coping is provided with a groove, and the groove is sleeved at the top end of the column during installation and is fixed by mortar; the bottom of the wallboard is provided with a groove, and the groove is sleeved at the top end of the wallboard during installation and is fixed by mortar;

step 4, wall pointing: 1:3 cement mortar is adopted to joint gaps on the side surfaces of the wind-resistant column grooves of the enclosing wall, and black silicone paste is adopted to seal the gaps; the joints of the wall boards are subjected to jointing by using black silicone structural adhesive, and the surface of the concrete is smooth and clean and reaches the quality standard of fair-faced concrete.

In the step 1, the checking standard is that the top surface elevation is +/-3 mm, and the installation verticality is +/-3 mm.

In the step 2, the checking standard is that the wall surface seam is +/-2 mm, and the wall surface verticality error is less than 3 mm.

In the step 3, the top of the prefabricated coping is drained in a bidirectional way, the gradient is 5 per mill, and a 10mm multiplied by 10mm water dripping line is arranged at the bottom of the coping.

In the step 3, the size of the bottom groove of the pillar coping is 260 multiplied by 10 mm; the size of the groove at the bottom of the wallboard capping is 70X 10 mm.
