Problems solved by technology

[0002] Usually, the traditional construction methods used in the construction of the reinforced concrete wall of the chimney include the derrickless hydraulic sliding form method and the vertical derrick displacement formwork method. Although the derrickless hydraulic sliding form method is convenient for construction and safe in operation, it is time-consuming for each process. High precision is required, otherwise, the concrete will be easily cracked; although the vertical derrick displacement formwork method can easily ensure the quality of the concrete, but the labor input is relatively large and the safety is poor

Embodiment Construction

[0008] The specific implementation of the present invention will be described in detail below in conjunction with the examples.

[0009] Taking the reinforced concrete wall of a chimney as an example with a height of 235m, the technological process is: foundation → cylinder seat → backfilling soil, setting up a laser room → applying a 3m high concrete cylinder on the foundation → assembly of the lifting operation platform system →Binding steel bars, supporting formwork, carrying out form-turning construction, pouring concrete, and lifting the operating platform system, such a cycle of repeated construction → halfway (90-100 meters) lifting the operating platform system modification → continue to turn the formwork to 235m → brush Navigation mark paint→removal of lifting operation platform.

[0010] The specific implementation method is as follows:

[0011] 1. Construction of the chimney body foundation: make the base, place the backfill, set up a laser room at the center of th...

Abstract

The invention relates to a hydraulic lifting rollover construction method of a chimney reinforced concrete shaft wall, which is mainly characterized in that hydraulic lifting is adopted to lift an operating platform system, but a chimney shaft wall construction template system adopts a rollover construction process; a supporting rod is penetrated through the center of a hydraulic jack; under the action of the periodical hydraulic power, the hydraulic jack climbs along the supporting rod to drive the operating platform and rise along with a raising derrick, whereas inner and outer suspension brackets which are fixedly connected together with the radial beam of the operating platform system are adopted to install the template system; and three layers of suspension brackets are arranged below the radial beam at intervals of every 1.8m, and scaffold boards and fine mesh nets are overspreaded on the three layers of suspension brackets. Compared with the traditional prior art, the construction method not only has the advantages of the prior art, but also has high construction speed and convenient operation, is economical and practical, can effectively ensure the construction engineering quality and construction safety and can save construction expenditures and lower construction cost.

Description

technical field [0001] The invention relates to a construction method for a reinforced concrete wall of a chimney, in particular to a construction method for hydraulically lifting and turning the reinforced concrete wall of a chimney, which is suitable for the construction of the reinforced concrete wall of a chimney. Background technique [0002] Usually, the traditional construction methods used in the construction of the reinforced concrete wall of the chimney include the derrickless hydraulic sliding form method and the vertical derrick displacement formwork method. Although the derrickless hydraulic sliding form method is convenient for construction and safe in operation, it is time-consuming for each process. High precision is required, otherwise, the concrete will be easily cracked; although the vertical derrick displacement formwork method can easily ensure the quality of the concrete, but the labor input is relatively large and the safety is poor.
