(54) METHOD FOR INSTALLING WATER TOWER

one

; The invention relates to the construction, and in particular to methods for constructing water towers with metal tanks on supports made of bearing elements or solid material.

A known method of erecting water towers, concludes with the lifting of the tower tank on an already mounted support. Thus, water towers are mounted with the walls of a tank of flexible elastic material and a rigid roof and bottom of the joint venture.

The disadvantage of this method is the necessity of extending the barrel of the tower to the full height of the tank. And unreliable operation of the tower, because over time, the walls of the tank of elastic material are subject to fatigue damage under alternating loads from water and wind.

The closest in technical essence to the invention is the construction of a water tower.

The reason is that for assembling the support and the tank, a water supply pipe with a tap 2 installed at its upper end is used.

This method has a number of significant drawbacks, since it provides for the assembly of the tank at the highest elevation of the tower, eliminates almost year-round construction of the towers due to the lack of a protective tent and does not exclude people from hanging under the load during the assembly of the tower and tank elements

The purpose of the invention is to simplify the floor and ensure safety by using the tank as a protective coating when mounting the tower,

Claims (2)

The goal is achieved by the fact that in the method of installation of a water tower, including the installation of an inlet water pipe, the installation of the GRU.T. After lifting the pipe, the tank is assembled on the base of the tower, and the bottom of the tank is attached under its roof for installation time. simultaneously with the erection of the support, and after the erection of the support they lower the bottom of the tank onto the support and weld it to the walls. FIG. 1 shows schematically the first stage of the construction of the tower - the rise of the supply pipe; in fig. 2 — assembling a tank with a bottom and a load-lifting device attached in its upper part; In the final stage of installation, with raising the tank to the design mark and simultaneously lowering the bottom on the support, the erection of the tower is carried out as follows. Initially, an inlet pipe 2 with an inventory extension 3 equipped with ropes k on the mobile yoke 5, ropes 6 and behind the root braces 7 on the fixed yoke 8 is installed on the foundation 1 at the fixed traverse 8 stops 9, fixing the movable yoke in the process of lifting. On the foundation of the tower around the pipe 2, the wall 10 of the tank with the roof 1 is temporarily fixed under the bottom 12, a load-lifting rotary device 13 is installed under the bottom, for example, a boom, and an assembly platform 1, with a rope 4 they lift the tank and the height of the shaft of the support, fixing it with surface stops 9 , thus providing the same safety requirements. As the tank moves upwards to ensure the stability of the water supply pipe 2, the horizontal connections 15 are installed in the batons. The elements of the support elements 16, connections 15 and the flight of stairs th 17 on the built suit of support made from the assembly platform It. After the erection of the support using hoists 18, passed through the temporary openings T9 in the roof 11, during the last stage of lifting the tank, the bottom of the tank is lowered onto the support, and then the load-lifting devices, extension extension and drive are removed t weld the bottom of the tank with its walls. In addition to the high degree of safety of installation work, the method can be used year-round, since all installation work is carried out in the internal volume of the tank, the roof and walls of which serve as a protective coating. In general, cost reduction for the construction of the tower by the proposed method reaches 15-20 of the cost of the tower. The invention of the method of installation of a water tower, including the installation of supplying a pipe with a water drainage pipe, installation of lifting mechanisms, erecting a support around the pipe on the foundation by building and raising the tank with walls, bottom and roof to the design mark, characterized in that in order to simplify installation and increase safety by using the tank as a protective coating when mounting the tower, after installing the pipe, the tank is assembled on the foundation of the support, and the bottom of the tank is attached under its roof during installation while raising the tank is carried out simultaneously with the erection of the support, and after the erection of the support they lower the bottom of the tank onto the support and weld it with the walls.
