Abstract

The invention discloses a method for horizontal dynamic controlled-freezing water stopping between pipe roofs. The method comprises the steps that temperature measuring pipes are arranged in top pipes; a controlled-freezing pipeline system is laid in the top pipes; the controlled freezing pipeline system is connected with a freezing device; controlled-freezing operation is conducted on soil between the top pipes, and a waters-stopping frozen curtain is formed between the top pipes; after the requirement for water stopping does not exist between the top pipes, soil is unfrozen, and thaw settlement track grouting is conducted. The method for horizontal dynamic controlled-freezing water stopping between the pipe roofs has the advantages that the water stopping effect is good, the influence to the water surface is small, safety and reliability are achieved, and operation is easy and convenient. In addition, the method can be adopted in the severe complicated and special geological conditions with soft soil, high-pressure water and the like, so that the environment adaptability is high, and the method is particularly suitable for water stopping construction between the pipe roofs in the section where a building is arranged or the surface requirement is strict under the complicated geographical conditions.

Description

technical field

[0001] The invention relates to the field of water sealing between pipe curtains, and more particularly relates to a horizontal dynamic controllable freezing water-stopping method between pipe curtains, which is suitable for water sealing construction between pipe curtains in the construction process of municipal pipe curtains. Background technique

[0002] Since 1971, when the pipe curtain method was first applied to the channel project of Kawase-Inae, Japan, it has been widely used in the construction of connecting channels such as crossing roads, railways, structures, and airports as a trenchless technology. In the construction of the pipe curtain method, the single pipes are connected on the side of the steel pipe by the lock to form a pipe row, and the water-stopping agent is injected into the gap of the lock to meet the water-stop requirement and form an advanced support.

[0003] The existing water-sealing construction technology between the pipe curta...
