Vertical shaft wall structure with water-swelling glue

Abstract

The invention discloses a vertical shaft wall structure with water-swelling glue, and relates to the technical field of vertical shaft wall structures. The vertical shaft wall structure aims at solving the problems that after an existing shaft wall is subjected to thermal expansion and cold contraction, water leakage occurs at the joint, and the sealing performance of the shaft wall is affected to a certain extent due to the fact that the water pressure borne by the shaft wall is large. According to the scheme, the vertical shaft wall structure comprises soil rock, wherein a first prefabricated shaft barrel is arranged in the soil rock, a second prefabricated shaft barrel is arranged at the bottom end of the first prefabricated shaft barrel, partition plates are arranged on the circumferential outer walls of the first prefabricated shaft barrel and the second prefabricated shaft barrel, a cement spraying layer is arranged on the inner wall of the soil rock, and a drainage layer is arranged between the cement spraying layer and the partition plates. The vertical shaft wall structure is novel in structure, the problem of water seepage after thermal expansion and cold contraction can be effectively solved, the water pressure borne by the shaft wall can be effectively reduced, meanwhile, the soil rock can be effectively prevented from losing stability and collapsing, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of shaft wall structures, in particular to a shaft wall structure with water-swellable glue. Background technique [0002] As a water-stopping material with excellent construction performance, expansion rubber is a water-swellable single-component sealant. Once hardened, it becomes a rubber elastic body with good recovery properties. After soaking in water, its own volume expands, thereby forming a water-stopping effect that fills the gap. The scope of use widely. [0003] Due to the large temperature difference between morning and evening, the wall structure of the vertical shaft will experience thermal expansion and contraction. After thermal expansion and cold contraction, water leakage will occur at the junction of the shaft wall, and when there is water, the shaft wall structure will bear The high water pressure will have a certain impact on the tightness of the shaft wall structure. Therefore, in orde...
