Inverted anchor recess anchor sealing device based on communicating vessel principle and construction process

Abstract

The invention discloses an inverted anchor recess anchor sealing device based on a communicating vessel principle and a construction process. The inverted anchor recess anchor sealing device comprisesa bottom mold plate, a mold expansion preventing structure, a grout inlet pipe and an air outlet pipe, wherein the bottom mold plate is arranged at an anchor recess opening of an inverted anchor recess in the bottom of a prestressed concrete structure in a supported mode; the mold expansion preventing structure is installed on the outward surface of the bottom mold plate, and the bottom mold plate is fixed to the anchor recess opening through the mold expansion preventing structure, so that a closed space is formed in the anchor recess while the anchor recess opening is sealed by the bottom mold plate; the grout inlet pipe penetrates through the bottom mold plate from the outside of the anchor recess and extends into the anchor recess; and the air outlet pipe penetrates through the bottommold plate from the outside of the anchor recess and extends to the top in the anchor recess. According to the inverted anchor recess anchor sealing device based on the communicating vessel principleand the construction process, the problem that a traditional anchor sealing construction process cannot be well applied to the inverted anchor recess can be effectively solved.

Description

technical field [0001] The invention relates to an inverted anchor hole sealing device based on the principle of a connector, and an inverted anchor hole sealing construction technology, which belongs to the technical field of prestressed concrete structure anchor sealing construction. Background technique [0002] With the development of science and technology, people put forward higher requirements for the full utilization and durability of materials. Although the reinforced concrete structure has improved the shortcomings of the low tensile strength of concrete, there are still unsolvable problems such as concrete cracking. The prestressed concrete structure is an efficient structure designed and built using high-performance materials, modern design theory and advanced construction technology. Compared with non-prestressed concrete structures, prestressed concrete structures not only have the advantages of large spanning capacity, good mechanical performance, superior pe...
