Concrete curing method by embedding pipe in structure

Abstract

The invention discloses a concrete curing method by embedding a pipe in a structure. A grouting pipe is embedded in a concrete structure; a water receiving opening is formed in the concrete structure;and maintenance water enters the grouting pipe through the water receiving opening, so that the concrete structure is cured. According to the invention, the novel use of the grouting pipe for curingis provided, so that the current situation that the structure, which is difficult for conventional curing operation, is difficult for curing in the early stage of curing caused by limited space is solved.

Description

technical field [0001] The invention relates to a concrete maintenance method, in particular to a concrete maintenance method for a structure embedded pipe, and belongs to the technical field of concrete maintenance. Background technique [0002] In the construction of concrete structures, maintenance is an important process to ensure the strength and durability of concrete during construction and reduce the quality defects such as cracks. However, it is limited by the work space and work progress, and it is most needed in the first 7 days after the final setting of the concrete structure. During the maintenance, the maintenance may not be in place due to reasons such as the narrow working space and the inability to dismantle the supporting structure. [0003] For structures such as underground passages and comprehensive pipe corridors under urban roads, this situation is particularly obvious, especially when the maintenance of wall panels is difficult to achieve, resulting ...

Problems solved by technology

[0002] In the construction of concrete structures, maintenance is an important process to ensure the strength and durability of concrete during construction, and to reduce the quality defects such as cracks. However, subject to the work space and work progress, it is most needed in the first 7 days after the final setting of the concrete structure. During the maintenance, the maintenance may not be in place due to reasons such as the narrow working space and the inability to remove the support structure

[0003] For structures such as underground passages and comprehensive pipe galleries under urban roads, this situation is particularly obvious, especially when the maintenance of wall panels is difficult to achieve, resulting in cracks in the wall panels, concrete failing to reach the corresponding strength, and durability decline and other quality defects
