Frozen area assembly type subway ventilation pavilion and construction method thereof
The invention discloses a frozen area assembly type subway ventilation pavilion and a construction method thereof, the frozen area assembly type subway ventilation pavilion is formed by vertically stacking a plurality of single-layer ventilation pavilion well bodies, each single-layer ventilation pavilion well body is formed by splicing left and right same C-shaped prefabricated parts, and ethylene propylene diene monomer waterproof layers are arranged on the inner and outer walls of the C-shaped prefabricated parts; the C-shaped prefabricated parts are connected in a mortise and tenon mode; the C-shaped prefabricated part is produced in a factory, so that the production efficiency is greatly improved, and the quality is convenient to guarantee and supervise; different from a cast-in-place construction mode, assembly is easy, the labor intensity of workers is reduced, and the labor safety is guaranteed; few supports are arranged, the formwork support demand is low, the concrete curing time is short, and the construction period is effectively shortened. The ventilation pavilion belongs to a semi-open-air structure and is easily influenced by temperature, and the ventilation pavilion construction method provided for seasonal freezing areas can avoid deterioration caused by interaction between concrete and frozen soil due to repeated freezing and thawing cycles, can also effectively weaken the frost heaving phenomenon, and prolongs the service life of the ventilation pavilion.
本发明公开了一种冻区装配式地铁风亭以及施工方法，冻区装配式地铁风亭，是由若干单层风亭井体上下叠置而成，单层风亭井体是由左右相同C型预制构件拼装而成，C型预制构件的内外壁设置三元乙丙防水层；C型预制构件之间为榫卯式连接；C型预制构件在工厂内生产，生产效率大幅度提高，便于质量的保证和监管；不同于现浇施工模式，组装简易，工人劳动强度降低，保证劳动安全性；支撑设置少、模板支护需求量低以及混凝土养护时间短，有效缩短工期。风亭属于半露天结构，易受温度影响，针对季冻区提出的风亭施工方法，可避免因反复冻融循环导致的混凝土与冻土之间相互作用发生劣化，亦可有效减弱冻胀现象，延长风亭使用寿命。
