Frost-and-expansion resistant protection body for water transmission tower of water reservoir, and arranging method thereof

Abstract

The invention discloses a frost-and-expansion resistant protection body for a water transmission tower of a water reservoir and an arranging method thereof. The frost-and-expansion resistant protection body for the water transmission tower of the water reservoir comprises a geomembrane, a polyethylene heat insulation plate, a composite geomembrane, angle steel and a steel plate, wherein the geomembrane is arranged on the outer surface of the water transmission tower; the polyethylene heat insulation plate is arranged on the outer surface of the geomembrane; the composite geomembrane is arranged on the outer surface of the polyethylene heat insulation plate; a plurality of pieces of angle steel are arranged at the edges and the corners of the water transmission tower outside the composite geomembrane; the steel plate is detachably connected with the angle steel; the arranging method comprises the following steps: tightly adhering the geomembrane to the outer surface of the water transmission tower; covering the polyethylene heat insulation plate on the geomembrane; adhering the four edges of the polyethylene heat insulation plate; adhering the composite geomembrane onto the outer surface of the polyethylene heat insulation plate; arranging the angle steel at the edges and the corners of the water transmission tower; connecting the steel plate with the angle steel by bolts; fixing the protection body. According to the frost-and-expansion resistant protection body for the water transmission tower of the water reservoir, the water transmission tower of the water reservoir can be protected very well, and the damage to the water transmission tower of the water reservoir under a low temperature is prevented.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and in particular relates to an anti-frost heaving protection body for a water transfer tower of a reservoir and a setting method thereof. Background technique [0002] In the northern cold region, the water surface of the reservoir water transfer tower freezes under the action of negative temperature in winter, and the reservoir water transfer tower will be damaged by frost heave under the action of ice thrust. At present, the reservoir in the northern cold region needs to take manual deicing measures every few days. The water transfer tower is deiced to reduce the frost heave damage to the reservoir water transfer tower, but manual deicing increases the engineering cost and the difficulty of deicing. Therefore, a measure to prevent the reservoir water transfer tower from frost heave damage is developed. It has important practical significance for anti-frost heaving of rese...

The water transfer tower is deiced to reduce the frost heave damage to the reservoir water transfer tower, but manual deicing increases the engineering cost and the difficulty of deicing. Therefore, a measure to prevent the reservoir water transfer tower from frost heave damage is developed. It has important practical significance for anti-frost heaving of reservoir water towers in cold northern regions
