Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] As shown in the figure, the main steps of the construction method of the present invention are:

[0025] (1) Concrete construction on the side wall and bottom: first construct the flue concrete cushion for the coke oven foundation flue, then construct the flue bottom plate 1 and the vertical wall reinforced concrete structure 2, and reserve reinforcement and fixation when constructing the vertical wall concrete Vertical angle steel or channel steel support for the flue elbow;

[0026] (2) Brick lining on the side wall and bottom: After removing the formwork and cleaning, build the refractory brick lining on the vertical wall of the coke oven foundation flue 3. Bottom lining, and lining on the vertical wall to the foot of the vertical wall (that is, the position below the vault, Here, the arched brick platform protrudes outwards and builds 3 layers of ...

Abstract

The invention discloses a coke oven basis flue fast construction method free of top die erecting. Top die erecting is avoided in coke oven basis flue construction. Firstly, concrete construction is performed on a side wall and a bottom, then, brick lining construction is performed on the side wall and the bottom, next, a flue bend is installed, an arch center is installed, and arch center brick lining construction and top concrete pouring are performed. According to the method, a lining is firstly constructed, a top plate concrete construction method is performed, and the problem that a flue space is narrow and small, and accordingly a die frame system is difficult to assemble and disassemble is effectively solved. Enough space exists for construction of a building furnace, and construction is convenient; cost is low, outwork is achieved, a safety coefficient is high, and construction quality is good.

Description

technical field [0001] The invention relates to a construction method for a coke oven foundation flue, in particular to a fast construction method for a coke oven foundation flue without supporting a top form. Background technique [0002] The foundation flue of the coke oven has always been a difficult point in the coke oven construction process because of its long length, narrow space, difficult material transportation during refractory masonry, and high schedule requirements. The traditional construction method is "construct the concrete structure first and then build the flue lining". The space is narrow, and it is difficult to remove the formwork (iron sheet), scaffolding, and wooden squares after the roof is poured, and the maintenance of the concrete also takes a long time. Lining masonry cannot quickly intervene in construction. There is not enough space during masonry, and it is difficult to feed materials. Feed through the flue bend will cause a large material lo...
