A new construction method of working well

Abstract

A construction method for a new type of working well, comprising a working well template, a working well formwork frame, and a suspension device, characterized in that the working well template is spliced ​​by several first standard blocks and second standard block bolts; One standard block and the second standard block are fixedly connected with a tamping port; the second standard block is provided with a pouring port for fixed connection; Adjacent blocks are fixedly connected; the working well formwork is assembled from formwork modules; the formwork module includes a column and a ring steel frame; the top of the column is provided with lifting lugs for welding and fixing; the suspension device is provided with a winch for fixing connection; the hoist is provided with traction steel rope and hanging lug stretching connection; the device uses standard blocks to build and construct the working well template to ensure that the dimensional accuracy of the upper and lower templates is the same; and the working well template is hoisted. Build, reduce the time required for disassembly and assembly, and improve work efficiency.

Description

technical field [0001] The invention relates to the field of working well construction, in particular to a novel working well construction method. 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 accuracy error of building temp...

[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
