The invention discloses a high-strength tent for polar exploration, which belongs to the field of polar tents. It is a high-strength tent for polar exploration. In this scheme, when too much snow is accumulated on the upper end of the outer reinforcement curtain, the snow board is used to store the snow under the weight of the snow. Under the action, it moves downward and drives the limit slider to move, triggers the trigger switch, starts the electric heating plate, heats the external reinforced curtain, melts the snow on the upper end of the external reinforced curtain, and makes a liquid layer between the external reinforced curtain and the snow. To reduce the friction between the snow and the outer reinforced curtain, so that the snow can slide down from the outer reinforced curtain under the action of its own weight, which can realize the timely cleaning of the snow with less energy without affecting On the premise of the normal operation of the life safety device in the tent, the snow in the tent should be cleaned up in time, so that it is not easy to threaten the whole tent due to the heavy snow on the tent, and it is not easy to cause a safety accident of the tent collapse.

The invention discloses a forming device for a circular-truncated-cone-shaped elevation concrete block for a floor slab. The forming device comprises two parallel clamping plates. A plurality of half circular truncated cone ring plates are arranged on the opposite sides of the clamping plates. The ring plates are paired between the two clamping plates to form a circular-truncated-cone-shaped die. A bed board on the side opposite to the corresponding ring plate is vertically arranged at the bottom of each clamping plate, and the two clamping plates are connected through at least two sets of paired bolts and nuts.
