Problems solved by technology
Moreover, the natural conditions of the construction are harsh, which often cause problems that the fixed slipform trusses are large in size and heavy in weight, and they are deep in the quagmire before they are transported to the Shiwei site. They are scrapped and cannot be used, which seriously affects the construction speed and construction quality.

Embodiment Construction
[0042] Such as Figure 1 to Figure 11 As shown, the present invention includes an electric welding machine 34, an operating table 36 and a distribution box 37, wherein:
[0043] Assembled frame, the assembled frame includes four angle steel rectangular frames and four angle steel columns 17, the four corners of the four angle steel rectangular frames 18 distributed at intervals are evenly distributed and fixed on the upper and lower ends and the upper and lower ends of the four angle steel columns between. Reinforcing angle steel 19 is provided between the opposite corners of the angle steel rectangular frame. Parallel cable-stayed angle steels 21 are arranged between the opposite corners of the same plane angle steel columns between the upper and lower angle steel rectangular frames. One end of several assembled frames is provided with a space frame 41 for inserting and sliding an assembled frame of another size from the side or the front. The space frame can be located in...

The invention belongs to an assembling type variable cross-section expanding and withdrawing slip form system and a construction method thereof. The assembling type variable cross-section expanding and withdrawing slip form system comprises inner and outer trusses and a portal formed by assembled frames, auxiliary discs, inner and outer mold plates, climbing penetration type hydraulic jacks and the like which form a system of a variable cross-section size. The construction method comprises the following steps: respectively manufacturing components such as the assembled frames according to sizes of designed thin-walled hollow piers, respectively assembling the inner and outer trusses applicable to design sizes of the thin-walled hollow piers by using bolts and screw nuts on a construction site, performing overall synchronous lifting on the inner and outer trusses, and the like. A plurality of truss units are formed in a modulation assembling mode, the plurality of the truss units are further assembled into the slip form truss system, and thus the slip form system has the advantages of being convenient and flexible to assemble, good in repeated use, possible in separated conveying, small in material quantity, applicable to pier stud cross sections of different sizes, rapid in construction speed, saving in time and labor, low in construction cost, good in construction quality, good in security and good in use effect.
Description
technical field [0001] The invention belongs to an assembled sliding form system with variable cross-section and a construction method thereof. Background technique [0002] In the construction of railway or highway bridge piers, factors such as unfixed and variable pier column dimensions in various road sections, large differences in pier bottom and top dimensions, and poor construction natural conditions are often encountered, so that the applicable range of fixed slipform trusses for casting reinforced concrete is narrow or limited. Out of service. And it is often necessary to prepare a large number of fixed slipform trusses suitable for different pier column sizes, which not only increases the cost of materials, but also causes time-consuming, laborious, slow speed, high cost and low efficiency in transportation, installation and construction. [0003] For example: 26 bridges are designed for the fifth branch of the Weldia-Mekelle Railway Project in Ethiopia, with a tot...
