Abstract

The invention relates to a method for leakage repairing of an aqueduct. An inner layer of an aqueduct body is provided with a template; a reinforcing layer is formed by pouring the template at the inner side of the aqueduct, wherein the template comprises a side template body, a bottom template body and an axillary angle template body, the side template body is arranged at the inner side of the vertical wall of the aqueduct body, the bottom template body is arranged on the bottom layer of the aqueduct body, the bottom template body is connected with the side template body through the axillaryangle template body, and the axillary angle template body is provided with multiple ribs. The template is a thin-wall detachable-free template, the thin-wall detachable-free template is utilized to form a lining layer on the inner wall of the aqueduct, then concrete is casted into a gap of the lining layer, the concrete and the thin-wall detachable-free template jointly form the reinforcing layerto effectively reinforce the osmotic damage of the aqueduct, the template does not need to be disassembled after construction, and the construction process is simple.

Description

technical field [0001] The invention relates to a method for repairing leakage of an aqueduct, which belongs to the field of water conservancy engineering, in particular to the field of repairing aqueducts in water conservancy projects. Background technique [0002] An aqueduct is an overhead water conveyance structure that conveys water across rivers, roads, hills, valleys, etc. It is one of the most widely used three-dimensional crossing structures in hydraulic structures. In addition to being used to transport canal water, it can also be used for flood discharge, sand discharge, navigation and diversion. With the South-to-North Water Diversion Project and the construction of domestic water conservancy infrastructure, aqueducts have been widely used, and large-scale aqueducts often use prestressing new technologies, and related research results have emerged one after another. In the long-distance water transfer project, the aqueduct is an important hydraulic structure. On...
