Novel working well formwork device and construction method thereof

Abstract

The invention discloses a novel working well formwork device and a construction method thereof. The novel working well formwork device comprises a working well formwork, a working well formwork frameand a suspension device, and the novel working well formwork device is characterized in that the working well formwork is formed by splicing a plurality of first standard blocks and second standard blocks through bolts; the first standard blocks and the second standard blocks are provided with tamping openings for fixed connection; the second standard blocks are provided with pouring openings forfixed connection; the working well formwork is provided with an oblique opening block, and the two sides of the oblique opening block are provided with adjacent blocks for fixed connection; the working well formwork frame is formed by assembling formwork frame modules; each formwork frame module comprises a stand column and an annular steel frame; the tops of the stand columns are provided with lifting lugs for welding and fixing; the suspension device is provided with a winch for fixed connection; and the winch is provided with a traction steel rope for being connected with the lifting lugs in a stretching and rolling manner. According to the device, the standard blocks are adopted for building and constructing the working well formwork, and the size precision of an upper-layer formwork and the size precision of a lower-layer formwork are ensured to be the same; and the working well formwork is built in a hoisting manner, the time needed for assembly and disassembly is shortened, andthe work efficiency is improved.

Description

technical field [0001] The invention relates to the field of working well construction, in particular to a novel working well formwork device and a construction method thereof. Background technique [0002] When most excavated shafts are constructed in sections, the thickness of the continuous wall changes, and it is necessary to excavate from top to bottom and keep the upper part fixed, and the lower part continuously establishes support; in ordinary construction, continuous errors are prone to occur when supports are established multiple times As a result, the size of the established formwork is inconsistent, and the roundness and verticality cannot be guaranteed; and in many cases, in order to ensure the dimensional accuracy, the formwork is often disassembled and assembled many times, and the formwork is not too long each time, so the current construction is either for Ensuring dimensional accuracy leads to low efficiency, or the pursuit of high efficiency leads to the a...

[0002] When most excavated shafts are constructed in sections, the thickness of the continuous wall changes, and it is necessary to excavate from top to bottom and keep the upper part fixed, and the lower part is continuously established for support; in normal construction, continuous errors are prone to occur when supports are established multiple times As a result, the size of the established formwork is inconsistent, and the roundness and verticality cannot be guaranteed; and in many cases, in order to ensure the dimensional accuracy, the formwork is often disassembled and assembled many times, and the formwork is not too long each time, so the current construction is either for Ensuring dimensional accuracy leads to low efficiency, or the pursuit of high efficiency leads to accuracy errors in building templates and roundness and verticality cannot be guaranteed
