Operation method for water communication thermal insulation in high and cold area

Abstract

The invention relates to an operation method for water communication thermal insulation in a high and cold area. The method at least comprises the steps of 1, arranging water inlet pipelines at the bottom of a concrete structure of a gate rail, wherein water returning pipelines are arranged at the upsides of the water inlet pipelines, the water inlet pipelines are connected with a boiler water inlet tower and are communicated with the water returning pipelines, the water inlet pipelines and the water returning pipelines are horizontally arranged in the concrete structure of the gate rail, and the water inlet pipelines are connected with the boiler water inlet tower and are communicated with the water returning pipelines; 2, heating the boiler water inlet tower, and improving the surface temperature of the concrete structure by hot water circulation of the water inlet pipelines and the water returning pipelines. The operation method has the excellent effects that the water inlet pipelines and the water returning pipelines are embedded in the concrete structure in the high and cold area, the concrete surface temperature is improved, the surface, where the gate rail is positioned, of the concrete structure is enabled not to ice, and the free opening and closing of the gate are ensured; the structure is simple, the operation is simple, the manufacturing cost is low and safe and reliable effects are realized.

Description

technical field [0001] The invention relates to the technical field of concrete water passage and heat preservation in alpine regions, in particular to an operation method for water passage and heat preservation of concrete in alpine regions. Background technique [0002] With the development of China's hydropower industry to Xinjiang, Qinghai and the alpine regions of western Tibet, the opening and closing of the gates in winter low temperature seasons is due to freezing problems, and the concrete and tracks of the gates are frozen, making it difficult to open and close the gates. [0003] Usually, the conventional method for opening and closing the gate is to use hot water to pour the frozen ice on the concrete of the gate track and the gate slot with hot water before opening and closing the gate, and make it melt before opening and closing the gate. If you can’t reach the proper position of the gate for treatment, the best effect is not ideal, resulting in damage to the w...

[0003] Usually, the conventional method for opening and closing the gate is to use hot water to pour the frozen ice on the concrete of the gate track and the gate slot with hot water before opening and closing the gate, and make it melt before opening and closing the gate. If you can’t reach the proper position of the gate for treatment, the best effect is not ideal, resulting in damage to the water seal of the gate when opening and closing, serious water leakage behind the gate, and what’s more, incomplete deicing, resulting in an embarrassing situation where the gate cannot be opened and closed normally , the consequences are very serious

[0004] The mechanical deicing or hot water melting ice used in the prior art has potential safety hazards, and the deicing is not complete and has poor practicability
