混凝土置換技術市場前景如何?
置換混凝土加固法是一項非常危險的施工過程,因此加固施工前應對施工安全進行評估。若施工對結構或構件的受力或安全有影響,應對其結構或構件在施工全過程中的承載狀態進行驗算,以便制訂合理的施工方案。對影響結構安全的構件應有專門的監控方案和應急處理措施。
Replacement concrete reinforcement method is a very dangerous construction process, so construction juyixiban.07858.net guangyou.07858.netshuzhi.07858.netchejiareqi.07858.netruhuaji.07858.netwenbanji.07858.netsafety should be evaluated before reinforcement construction. If the construction has an impact on the stress or safety of the structure or component, the bearing state of the structure or component in the whole construction process should be checked so as to formulate a reasonable construction plan. Specialized monitoring and emergency measures should be taken for the components affecting structural safety.
混凝土置換技術加固一定要注意的事
Matters needing attention in reinforcement of concrete replacement technology
1、用置換混凝土加固法加固混凝土構件時,非置換部分的原構件混凝土強度等級按現場檢測結構不應低于該混凝土結構建造時規定的強度等級。
1. When the replacement concrete reinforcement method is used to reinforce concrete members, the strength grade of the original component of the non-replacement part shall not be lower than the strength grade specified in the construction of the concrete structure according to the site inspection structure.
2、用這種方法加固梁式構件時,要對原結構、構件在施工全過程中的承載狀態進行驗算、觀測和控制,置換界面處的混凝土不應出現拉應力。如果控制有困難,要采取支頂等措施進行卸荷。
2. When reinforcing beam-type members with this method, checking calculation, observation and control should be carried out on the bearing state of the original structure and members during the whole construction process, and tensile stress should not occur at the replacement interface of concrete. If the control is difficult, measures such as supporting roof should be taken to unload.
混凝土置換技術要保證新老混凝土間的結合能力,原結構結合面必須進行鑿毛處理,剔除一切風化酥松層、碳化銹蝕層及嚴重油污層,直至完全露出堅實的基層為止,并在此基層上鑿毛,使表面凹凸差約為5mm,然后用水沖洗干凈,并在澆筑混凝土前涂刷混凝土界面結合劑一道。
In order to ensure the bonding ability between new and old concrete, the original structural joint surface must be chiseled, all weathered and loose layers, carbonated and rusted layers and serious oil stain layers must be removed until the solid base is completely exposed, and the groove is chiseled on the base so as to make the surface concave and convex difference about 5mm, and then rinsed with water and brushed the concrete interface before pouring concrete. Binder together.
對于較薄的混凝土加固層,首i選噴射混凝土澆筑工藝。該法施工工藝簡單、適應性強,并具有成熟的設計和施工經驗;適用于梁、板、柱、墻和一般構造物的混凝土的加固;但現場施工的濕作業時間長,對生產和生活有一定的影響,且加固后的建筑物凈空有一定的減小。
For the thinner reinforced concrete layer, shotcrete casting technology is the first choice. The construction technology of this method is simple, adaptable and has mature design and construction experience. It is suitable for concrete reinforcement of beams, slabs, columns, walls and general structures. But the wet operation time of field construction is long, which has a certain impact on production and life, and the clearance of reinforced buildings is reduced to a certain extent.
