Abstract
The invention discloses a kind of renovation technique of old concrete post, including A, fresh concrete, a certain amount of streptomyces microflavus bacterium powder and calcium lactate or calcium acetate are added into fresh concrete；Formwork for placing is installed on concrete column, fresh concrete is injected into template B,；C, once, then to junction CO2 gases are injected 1 hour in every 68 hours sprinkling pure water of fresh concrete and old concrete post junction；D, concrete setting is treated in maintenance.The invention also discloses the structure of transvers plate used in the renovation technique of above-mentioned old concrete post.The CO2 in the adsorbable conversion air of streptomyces microflavus in the present invention, the CO2 that the microorganism can be adsorbed in conversion air turn into CO3 2‑, and Ca2+ and CO in calcium lactate or calcium acetate3 2‑Fresh concrete preferably can be connected by reaction generation CaCO3 with old concrete post junction, improve both bond strengths.
Description
Technical field
The present invention relates to a kind of renovation technique of old concrete post.The invention further relates to the reparation work of above-mentioned old concrete post
The structure of transvers plate used in skill.
Background technology
During traditional cylinder is repaired, concrete is typically directly filled into the cylinder breakage of template encirclement, but newly
Mixed concrete and cylinder this body concrete are difficult strong bonded, cause the breakage of repairing to be readily formed crack, long-term use of
Easily peeled off afterwards from cylinder.
The content of the invention
The technical problems to be solved by the invention, which are to provide one kind, can make fresh concrete and cylinder bond strength higher
Old concrete post renovation technique.The technical problems to be solved by the invention also include providing a kind of above-mentioned old concrete post
The structure of transvers plate used in renovation technique.
Therefore, the renovation technique of old concrete post provided by the invention, it is characterized in that：Including A, fresh concrete, Xiang Xin
A certain amount of streptomyces microflavus bacterium powder and calcium lactate or calcium acetate are added in mixed concrete；B, installation pours mould on concrete column
Plate, fresh concrete is injected into template；C, pure water is sprayed per 6-8 hours in fresh concrete and old concrete post junction
Once, then to junction CO2 gases are injected 1 hour, pressure 0.1MPa；D, concrete setting is treated in maintenance.
The structure of transvers plate used in the renovation technique of above-mentioned old concrete post provided by the invention includes four pieces of templates, at least
Plug hole is carried in one piece of template, blocking is configured with plug hole, banding has cross bar in template, and the both ends of cross bar carry through hole,
The through hole of Screw arbor with nut at both-ends through previous cross bar and rear side cross bar connected to drawing, and the template of each pair Relative distribution is along height side
Coordinate Screw arbor with nut at both-ends to be fixedly clamped to two pairs of cross bars are at least configured with, adopted between template at the cooperation of template and damaged surface
Strengthen sealing with seal with elastometic washer and using fluid sealant.
The technique effect of the present invention：The streptomyces microflavus used in the present invention can adsorb the CO2 in conversion air, and this is micro-
The CO2 that biology can be adsorbed in conversion air turns into CO3 2-, and Ca2+ and CO in calcium lactate or calcium acetate3 2-Reaction generation
CaCO3, it is high that fresh concrete and old concrete post junction are realized that chemical reaction forms intensity so as to preferably
CaCO3, improve both bond strengths.
Brief description of the drawings
