Problems solved by technology

[0004] The construction of the flue roof in the traditional construction technology is to build the vault mold of the flue roof as a whole after the concrete construction of the straight wall section, and then pour the overall concrete of the flue roof. First, the measures required for construction are more expensive. Second, the site needs to be carried out according to the construction sequence, so the process flow is long and the construction period is long

Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings, but it should be pointed out that the implementation of the present invention is not limited to the following embodiments.

[0024] Such as Figure 1-Figure 4 As shown, a rapid construction method for the flue roof, the flue roof is prefabricated in sections, and in the construction period, the section prefabrication of the flue roof and the concrete construction of the straight wall section, the lining of the straight wall section, and the arch The construction of tire and vault lining is carried out at the same time, which effectively shortens the construction period; the specific steps are as follows:

[0025] 1) Carry out support, precipitation and earthwork excavation according to the normal sequence of construction, and then apply concrete for the flue foundation;

[0026] 2) Carry out segmental prefabrication of the vault concrete structure, and at the same tim...

Abstract

The invention provides a flue top plate rapid construction method. A flue top plate is preliminarily fabricated in a sectional mode, and in a construction period, flue top-plate sectional pre-fabrication processing, straight-wall-section concrete construction, straight-wall-section lining masonry construction, and arch-moulding-bed and vault lining masonry construction are conducted at the same time, so that the construction period is effectively shortened. Compared with the prior art, the flue top plate rapid construction method has the advantages that the construction of a flue top-plate segment and the construction of a lower straight wall segment are conducted simultaneously, so that the construction period is shortened; a vault concrete structure is preliminarily fabricated in an off-site mode, so that the fabrication accuracy is high, and the quality is easily ensured; a vault mould can be fabricated by being divided into small segments and can be recycled, so that measure expenses are saved.

Description

technical field [0001] The invention relates to the technical field of flue roof construction, in particular to a rapid construction method for a flue roof. Background technique [0002] The flue is generally divided into a straight wall section and an upper semicircular vault section (flue roof). According to different process and design requirements, concrete structures, refractory insulation materials, masonry linings, etc. are arranged from the outside to the inside. . It is in a pressurized working state so that it needs to meet the requirements of airtightness, and also needs to meet the installation requirements of various components required by the process; on the site layout plan, the flue is long, and most of the designs are underground. Or semi-underground structure, resulting in a large impact on the temporary land use of the site during the flue construction stage, and a relatively large adverse impact on the temporary roads on site and surrounding construction...
