Abstract
The invention discloses a container cofferdam structure and a container cofferdam method, belongs to the field of water conservancy projects, and aims to realize completion of a bridge repair cofferdam in an efficient, modularized and low-cost mode. The container cofferdam structure comprises a substrate layer, a cofferdam wall body and a backfill layer, the cofferdam wall body is supported on the substrate layer and forms a backfill area with the substrate layer in a surrounding manner, a backfill area is filled with the backfill layer, the cofferdam wall body comprises containers, gabions and gabions which are sequentially arranged around the backfill area, the gabions are arranged on the outer sides of the containers, the gabions are arranged on the tops of the containers, the adjacent containers are fixedly connected through a connecting device, and the gabions are fixedly connected with the containers. According to the container cofferdam structure and the container cofferdam method, through cooperation of the containers and the gabions, the service life of the containers is prolonged while the wave dissipation and anti-scouring performance of the cofferdam is guaranteed, so that the service life of the cofferdam is prolonged, the integrity of the cofferdam is improved, and the construction quality is guaranteed; the containers and the gabions form integral modules correspondingly, so that the construction efficiency is higher; and local resources such as waste containers can be fully utilized according to local conditions, and therefore the resources are utilized to the maximum extent.
Description
technical field [0001] The invention belongs to the field of water conservancy engineering, in particular to a container cofferdam structure and a container cofferdam method. Background technique [0002] Cofferdam refers to the temporary enclosure structure built for the construction of permanent water conservancy facilities in the construction of water conservancy projects, which can be dismantled after use, or can be used as a part of formal buildings. [0003] In areas with tropical rain forest environment, its unique geographical resource environment makes it rich in river resources. Due to the excessive precipitation in the flood season every year, bridges along the river are often damaged during the flood season, and the foundations of most bridge abutments are damaged, threatening local traffic. Safe, urgent repairs required. Most of the existing emergency repair methods are to re-cofferdam and build the abutment foundation. The cofferdam structure usually includes ...
