Construction method capable of replacing steel support substitution by full space supports

Abstract

The invention discloses a construction method capable of replacing steel support substitution by full space supports. The construction method particularly comprises the following steps: (1) after the bottom plate construction of a subway station main body structure is finished, constructing side walls at the bottom, utilizing side pressure generated during concrete pouring and auxiliary providing a fastener to guarantee that the horizontal direction of the full space supports to be closely attached and propped tightly, and pouring the side walls and middle plates simultaneously; (3) after the bottom plate and the side walls under the steel support substitution are poured and reach the strength, continuously erecting the full space supports; (3) after erecting the full space supports in the step (2), disassembling third steel supports on part of the full space supports, continuously erecting the full space supports and constructing the middle plates and the side walls of the main body structure; and (4) after the construction of the main body structure is finished and the strength reaches the design requirement, disassembling the full space supports. According to the construction method, the procedures can be simplified, the work efficiency can be improved, the construction period can be shortened, construction safety and convenience are improved, the construction cost is saved and the construction efficiency is improved.

Description

technical field [0001] The invention relates to an optimal design for replacing steel bracing with full-wall brackets in the construction process of a main structure during the construction of a subway station, in particular to a construction method for replacing steel braces with full-wall brackets. Background technique [0002] In the construction process of the main structure of the open-cut Shunzuo subway station, it is necessary to use steel support and full-wall support, such as figure 1 structure is shown. The existing construction method is: after the construction of the station floor 1 is completed, when the side wall 2 is constructed, the first part of the full hall support 3 needs to be erected. The enclosure structure system composed of the enclosure structure 6, the second steel support 7, and the first concrete support 8 is stable. The third steel support 9 is removed, and the second part of the full hall support 3 is continued to be erected, and the side wall...

AI Technical Summary

Problems solved by technology

[0004] (1) The construction process of steel support 4 is complicated, the precision requirement is high, and the operation is difficult;

[0005] (2) The steel support 4 weighs several tons. When it is dismantled, the main structure has been completed, the working space is narrow, and it is difficult for large machinery to enter. Manual dismantling may easily cause injuries;

[0006] (3) During the erection process of the full house support 3, there is overlap with the steel support 4 in space, and the steel support 4 is likely to be disturbed during the construction of the full support 3, and the installation causes the steel support 4 to fall off, resulting in safety accidents
