Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0025] The X-shaped column construction method of the air cooling tower of the present invention comprises the following steps:

[0026] a. Calculate the construction load during the construction of the X-column of the air-cooling tower according to the construction drawings of the X-column of the air-cooling tower, and calculate the erection density of the scaffold 6 according to the construction load;

[0027] b. Use computer software to draw a three-dimensional diagram of the X-shaped column of the air-cooling tower in proportion, project the central control point 7 and the control point 8 at the corner of the air-cooling tower X-shaped column on the upper and lower ends of the air-cooling tower to the annular foundation 9, and use the software to mark output data;

Abstract

The invention discloses an air cooling tower X-shaped pillar construction method and belongs to the field of construction. An air cooling tower X-shaped pillar graphic model is drawn by computer software according to a proportion, the center control point and the corner control point of an air cooling tower X-shaped pillar are projected to an annular foundation from the upper portion of the air cooling tower X-shaped pillar to work out data. Practical measurement on control points in the field are carried out by utilizing a total station, oil paint is used for marking, the inclined angle of a joint bar is well adjusted according to the oil paint mark, and the joint bar is inserted into a buttress and is firmly fixed. Other subsequent control points are marked again on a rough terrace inside an air cooling tower. Steel bar frames of the air cooling tower X-shaped pillar are bound and connected and a formwork is fixed according to the marked control points, and meanwhile a scaffold is built. The actual positions of all control points are verified again, and concrete is poured. Due to the fact that the computer software is utilized for projecting the air cooling tower X-shaped pillar and determining the control points, compared with the method that the control points are mapped according to graph paper one by one, the method is faster and more accurate, steel bars and the formwork can be verified conveniently in the process of construction, and the period of construction is shortened.

Description

technical field [0001] The invention relates to a building construction method, in particular to a construction method for an X-shaped column of an air cooling tower with a short construction period. Background technique [0002] In recent years, thermal power construction in Xinjiang is in full swing. The geographical conditions of this area are special: coal resources are abundant, but water resources are scarce. The circulating cooling system of conventional thermal power wet cooling units is no longer suitable for local conditions due to excessive loss of circulating water. The air-cooled unit uses air to cool the steam turbine exhaust steam condensing device. Regardless of whether the circulating cooling water is an indirect air-cooling method with a closed cycle or a direct air-cooling method without circulating cooling water, there is almost no loss of circulating water, and only boiler replenishment water and other water are required. The water consumption of the a...
