[0003] For intercooling towers with a diameter less than 80m, the existing construction methods, such as the Chinese invention patent application number 201711082436. The construction method using the tower crane is not applicable to the construction of the intercooling tower with a diameter exceeding 80m. There is no construction precedent in China for the intercooling tower with such a large diameter steel structure. Therefore, a construction method with high reliability and good safety performance is urgently needed

Embodiment Construction
[0033]Combinefigure 1 withfigure 2As shown, the present invention has a cooled tower in the form of a steel structure in a steel structure having a high diameter of 102 meters from a bottom diameter of 102 meters, wherein the censored tower steel structure cone section 101 is 55 meters high. The censored tower steel structure direct section 102 is located at 55-175 meters, and the censored tower steel structure reinforcement ring 103 has a total of 5 floors, and the 5-layer reinforcing ring is distributed in the straight section, the spacing 30m is arranged, and the 0-55 m steel structure improvement segment There is 5 layers of strengthening ring steel structure and its strengthening ring connector, loop track, excluding the weight of the affiliated platform and 2 mobile tower 104, with a total weight of 0-55 meters to increase the total weight of 1683.33 tons, 55 meters. In average cloth, the plug is not less than the increase of 80 tons of lifting force. The total amount of total...

The hydraulic lifting construction method of the large-scale all-steel inter-cooling tower of the present invention includes the lifting construction of the steel structure cone section, the steel structure cylinder section lifting construction and the strengthening ring lifting construction. First, the cone section tripod is installed on the ground, and the assembly and welding are completed. Layer reinforcement ring, then fix the hydraulic lifting mechanism, use the hydraulic lifting mechanism to lift the multi-layer reinforcement ring to the top of the cone section as a whole, and use the mobile tower crane to connect the first layer of the straight tube section with the cone section. One layer of reinforcement ring is installed, and then the remaining reinforcement ring is lifted to the top of the first layer of the straight section, and the second layer of the straight section is connected with the first layer of the straight section and the second layer of the reinforcement ring by using a mobile tower crane. The method is installed all the way to the top floor. The invention divides the lifting construction of the super high building into multi-step and multi-process construction, which can realize the hydraulic lifting construction of the large-scale all-steel inter-cooling tower, and the lifting process method is advanced, feasible, safe and reliable.
Description
Technical field[0001]The present invention relates to the construction techniques of a large overall steel structure interchangeable tower, and in particular, a large steel structure is a hydraulic improvement construction method.Background technique[0002]A project requires two-piece steel structural form, which consists of a lower cone section, an upper cylindrical section, and a reinforced ring. The lower cone section, the upper cylindrical section and the reinforcing ring are used with a triangular structure, wherein the lower cone segments and the upper cylindrical section also include a metal strobe. The cooled tower is 175m, the bottom diameter is 150m, the upper diameter is 102m, and the total cooling tower in the form of a single steel structure is 8,500 tons.[0003]For more than 80m, the existing construction method, such as the application number of 201711082436.x, using tower crane construction, construction, construction, the temporary platform is air installation, high d...
