specific Embodiment 1
[0037] Specific embodiment one, such as Figure 1 to Figure 5 as shown,
[0038] The slipform construction operation platform for double-wall concrete silos includes: inner wall lifting system, outer wall lifting system, and public auxiliary facilities; among them,
[0039] The inner cylinder wall lifting system includes: inner cylinder wall opening frame 1, inner cylinder wall inner purlin 3, inner cylinder wall peripheral purlin 4, inner cylinder wall inner formwork 8, inner cylinder wall outer formwork 9, inner cylinder wall inner middle platform 12. Middle platform 13 outside the inner cylinder wall, upper platform 14 outside the inner cylinder wall, upper platform 15 inside the inner cylinder wall, lower platform 20 outside the inner cylinder wall, lower platform 31 inside the inner cylinder wall, hydraulic jack 22 for the inner cylinder wall, cylinder wall support rod 23.
[0040] The outer cylinder wall lifting system includes: outer cylinder wall opening frame 2, out...
specific Embodiment 2
[0057] Specific embodiment two, such as Figure 1 to Figure 5 as shown,
[0058] The construction method of the sliding formwork operation platform of the double-walled concrete silo, first, the inner cone of the silo is constructed to the bottom of the inner wall, and then the pre-installed outer wall sliding formwork is lifted to +22.0m, and the inner The bottom of the cylinder wall is flush, remove the original central steel ring and tie reinforcement, and then start to assemble the inner cylinder wall lifting system according to the following steps:
[0059] The first step is to install the lifting frame of the inner cylinder wall. The jacks of all the lifting frames are at the same level and fixed with vertical and horizontal rods. The spacing between the opening frames is 1200mm-1300mm. Appropriate adjustments;
[0060] The second step is to install the inner and outer purlins of the inner cylinder wall. The installation of the inner and outer purlins needs to consider...

Abstract
The invention discloses a double-cylinder-wall concrete silo slip form construction operation platform and a construction method. The double-cylinder-wall concrete silo slip form construction operation platform comprises an outer cylinder wall lifting system and an inner cylinder wall lifting system which are synchronously lifted, wherein the outer cylinder wall lifting system and the inner cylinder wall lifting system each comprise an inner side platform and an outer side platform, each of the inner side platforms and the outer side platforms comprises an upper layer, a middle layer and a lower layer, and the three layers of platform bodies on the outer side of the inner cylinder wall and the three layers of platform bodies of the inner side of the outer cylinder wall are correspondinglyconnected into a whole; and the upper-layer platform bodies are used for temporarily stacking slip form construction materials, the middle-layer platform bodies are used for steel bar binding, concrete transportation and pouring and tamping space, and the lower-layer platform bodies are used as a platform for receiving light, maintaining and checking after concrete is out of the forms. The three layers of platform bodies are reasonable in work division, and the requirement for slip form simultaneous lifting of a double-cylinder-wall silo is effectively met. By means of the double-cylinder-wallconcrete silo slip form construction operation platform and the construction method, the inner cylinder wall and the outer cylinder wall are connected into the whole on the basis of an original single-cylinder-wall slip form, so that the overall stability of a slip form system is improved, the slip form is lifted through the double cylinder walls at the same time, and the construction period is greatly shortened.
Description
technical field [0001] The invention belongs to the field of slip-form construction platforms, and in particular relates to a slip-form construction operation platform and a construction method for a double-wall concrete silo. Background technique [0002] In the process of cement plant production line, silos are indispensable. For the needs of the process or for the same silo to be able to hold cement of different specifications, in order to achieve the purpose of building as few silos as possible and reducing investment, so the construction Double-wall silos, so-called double-wall silos, are silos that have two inner and outer walls in one silo. [0003] Tall silos are generally constructed by sliding formwork, while double-walled silos are currently rare at home and abroad. The existing double-walled silos are constructed using separate sliding formwork for the inner and outer walls. This method of separate operation makes the construction The quality is difficult to gua...
