Method for lifting inverted cone shell water tank of reinforced concrete water tower

Abstract

The invention relates to a method for lifting an inverted cone shell water tank of a reinforced concrete water tower. The method comprises the following steps of: positioning a suspension rod, setting hydraulic equipment in place, primarily lifting the water tank, assembling a suspension wire rod on a support of an upper ring beam of the water tank, and placing lifting steel wedges hanged by steel wires outside a branch cylinder wall, wherein the lifting steel wedges are evenly distributed along the branch cylinder wall at 2,000 millimeter intervals, and tips support the bottom part of the water tank and are arranged in the gap between a lower ring beam and the branch cylinder wall; and when the water tank is lifted, making the steel wedges lifted along with the water tank; hanging suspension feet-hands, fixing the water tank at a high altitude, disassembling the lifting equipment, and casting ring plate concrete. The method fundamentally solves the problem that the water tank swings and bumps the cylinder wall when lifted; when the lifting reinforced bars are broken and the water tank falls off, the lifting steel wedges can fix the water tank on the branch cylinder, so that the huge loss caused by the broken reinforced bar and the falling off of the water tank is avoided; and by the method, the water tank can be stably, safely and quickly lifted up to the designed elevation of the cylinder top. By adopting the method, two hot rolling and two cold rolling 100t safety water towers of the Wuhan Iron and Steel, two continuous casting 200t and 800t water towers of the Wuhan Iron and Steel and the like can be successfully assembled.

Description

technical field [0001] The invention relates to a method for lifting an inverted conical shell water tank of a reinforced concrete water tower. Background technique [0002] The reinforced concrete inverted cone water tower is an essential engineering component of the hot rolling and cold rolling production line of the steel plant. It uses the water inlet pipe to the water tower water tank to store water, and uses the water outlet pipe to deliver water to ensure that the steel plant accident or safety needs water. . [0003] The conventional methods for lifting the water tower and water tank are: positioning the boom, putting the hydraulic equipment in place, initially raising the water tank, lifting the water tank normally, hanging scaffolding, fixing the water tank in place at high altitude, removing the lifting equipment, and pouring the ring-slab concrete. Disadvantages of this method: the water tank is prone to swing when it is lifted, colliding with the cylinder wall,...

Problems solved by technology

[0006] The invention fundamentally solves the problem that the water tank swings and collides with the cylinder wall when it is lifted; and when the lifting steel bar is broken and the water tank slides down, the steel wedge can be used to fix the water tank on the support tube, so as to avoid the huge loss caused by the broken lifting steel bar and the water tank slipping down. Problem; can lift the water tank to the design elevation of the top of the cylinder smoothly, safely and quickly
