Problems solved by technology

[0003] In traditional construction, the overall casing + large-volume concrete bottom seal water-stop scheme is often used. In recent years, new water-stop methods such as water-stop trays + inflatable capsules have also appeared. Under these conditions, the cost of the water stop device is high and the construction efficiency is low, so it is very necessary to optimize the related water stop technology

Abstract

The invention discloses an underwater water stop structure for a prefabricated abutment and a construction method thereof. The underwater water stop structure is arranged between a steel pipe pile and the prefabricated abutment, the prefabricated abutment is arranged on the outer side of the steel pipe pile, and the underwater water stop structure is characterized in that the underwater water stop structure comprises a first water stop structure body which is cylindrical and sleeves the steel pipe pile; a second water stop structure which is in an annular plate shape, the outer side of the first water stop structure is sleeved with the second water stop structure, the second water stop structure is located at the bottom of the prefabricated bearing platform, and the annular-plate-shaped upper wall of the second water stop structure is attached to the bottom of the prefabricated bearing platform; and a plurality of third water stop structures, wherein the space between the first water stop structure and the steel sheet pile and the space between the second water stop structure and the bottom of the prefabricated bearing platform are filled with the third water stop structures. The underwater water stop structure provided by the invention has the technical effects of quickness, effectiveness in water stop, simple water stop system and convenience and quickness in construction method. The structure can be widely applied to the technical field of water stop structures of prefabricated piers.

Description

technical field [0001] The invention relates to the technical field of water-stop structures for prefabricated piers. More specifically, the present invention relates to an underwater water-stop structure for prefabricated abutments and a construction method thereof. Background technique [0002] There are more and more large-scale cross-river and sea-crossing bridges in my country, and the construction window period is very limited under harsh working conditions. In order to reduce the impact of environmental factors and improve construction efficiency, the foundation design puts forward the guidelines of "large-scale, factory-like, standardized, and assembled". The post-cast concrete is used for wet bonding between them. Under such conditions, how to ensure that the gap between the cap and the steel pipe wall can be successfully sealed has become a key control factor for the success of foundation construction. [0003] In traditional construction, the overall casing + l...
