Problems solved by technology
However, in the construction of mountain tunnels in severe cold areas, ordinary stainless steel water tanks cannot transport engineering water to the construction site in a low-temperature environment in a timely manner at a suitable construction temperature, and can only store engineering water outside the construction site in areas with suitable temperatures. It is very inconvenient to use in some projects with tight construction schedules and long mountain tunnels
[0005] Because the construction water is used intermittently, water pipes cannot be used for water supply in the tunnel through the mountain, because the water in the pipes will freeze

The invention relates to a movable-type heat preservation device for mountain tunnel winter construction of a severe cold region. The movable-type heat preservation device comprises a tank body, an opening is formed in the top of the tank body, wheels are arranged at the bottom of the tank body which is provided with a first head cover and a second head cover, the first head cover is fixedly connected with the tank body, the second head cover is movably connected with the tank body, and a water inflow and outflow opening is formed in the first head cover. By means of the movable-type heat preservation device for the mountain tunnel winter construction of the severe cold region, a water tank can provide construction water for a mountain tunnel construction operation region of the severe cold region, and it can be guaranteed that the construction water is kept at an appropriate construction temperature simultaneously.
Description
technical field [0001] The invention relates to the field of tunnel engineering equipment, in particular to a mobile thermal insulation device for winter construction of tunnels in severe cold regions. Background technique [0002] In winter in severe cold regions, the construction of mountain-crossing tunnels is relatively difficult, and cold weather has a great impact on the construction of mountain-crossing tunnels, especially the influence of cold weather on the temperature of construction water in concrete construction. The temperature of construction water determines the degree of cement hydration, and the speed of concrete strength development is proportional to the temperature of construction water, or the higher the temperature of construction water, the faster the hydration rate of cement and the higher the development of concrete strength . [0003] However, the low temperature of the construction water will cause the strength of the concrete to not increase afte...
