Construction method of structural combined ice column with bamboo framework

Abstract

The invention discloses a construction method of a structural combined ice column with a bamboo framework. The construction method comprises the following steps: designing and processing each plate sheet of a timber formwork; forming filling holes in the same side of each bamboo joint section of the hollow bamboo wood; transporting the hollow bamboo wood to a required position of the polar region; pouring liquid water into the bamboo joints from each filling hole; after the water is solidified to form an ice body, symmetrically arranging the hollow bamboo wood to form a circle; bending a long bamboo chip, and hooping the long bamboo chip onto the outer side of the symmetrically arranged bamboo wood; binding with binding wires to form the bamboo framework; transversely inserting one end of a prefabricated steel nail body into the ice body in the hollow bamboo wood from the outer wall of the hollow bamboo wood; transversely inserting one end of the prefabricated steel nail body into the ice body in the hollow bamboo wood from the outer surface of the long bamboo chip along the long edge direction of the long bamboo chip; and assembling the timber formwork on site, placing the bamboo framework in the assembled timber formwork, adding the liquid water into the timber formwork, and after the ice column main body is formed, removing the timber formwork. Local materials can be used and can be recycled, and therefore, environmental pollution to the polar region environment is avoided.

Description

technical field [0001] The invention relates to a construction method of a composite structure, in particular to a construction method of a structural composite icicle with a bamboo skeleton. Background technique [0002] In the Antarctic or Arctic scientific research stations, in order not to cause environmental pollution and to facilitate construction, concrete is generally not poured in extreme environments, and steel structures are used instead. However, steel will appear cold and brittle in a cold environment, and the brittleness of the material will increase significantly. In addition, the thermal conductivity of steel is excellent, and cold bridges will be formed in the building, which is not conducive to heat preservation; the hot air in the room will be dissipated to the cold outdoor environment through the steel, resulting in a waste of indoor energy; and the long-term use of steel in the coastal environment The effect of sea breeze and sea water will pose great c...

Problems solved by technology

However, it is difficult to ensure that the components will not be plastically deformed during transportation and hoisting, and the polar environment is significantly different from the factory pre-assembled environment

Even if the factory can pre-assemble, it cannot fully guarantee that it can be assembled smoothly in the polar environment

At the same time, when the section steel structure is damaged, needs to be remodeled, needs to be relocated, or does not need to be used, it cannot be completely recycled and reused. If it is discarded at will, it will cause pollution to the polar environment. When transported back to the inland, the overall structure is difficult to transport and the transportation cost is high.
