Abstract

The invention relates to the technical field of mine construction, and particularly discloses a sleeve wall construction method based on a structural formwork. After a shaft design drawing is completed, the prefabricated structural formwork is designed and machined according to the shaft design drawing, and a prefabricated formwork is obtained; and after steel bars are bound, the prefabricated formwork is erected, and then concrete pouring is conducted; and after concrete pouring is completed, an upper-layer formwork is directly mounted, and pouring is conducted in sequence. Through the construction method, the formwork does not need to be dismounted, the construction progress can be accelerated, and the construction speed is increased.

Description

technical field [0001] The invention relates to the technical field of mine construction, in particular to a wall construction method based on a structural template. Background technique [0002] Shaft casing wall construction is widely used in shaft construction because of its good waterproof performance and stress conditions. The existing vertical shaft casing wall construction technology mainly includes two construction methods: slip form and reverse form. [0003] Slip form construction is to use a large formwork with its own jacking device to pour concrete after the steel bars are bound, and the formwork is raised through the jacking device to achieve continuous construction. The advantage of this construction process is that continuous pouring does not produce stubble joints, but the disadvantage is that the strength of the concrete is low, and it is difficult to control the construction quality during rapid construction. Inverted formwork construction mainly uses mu...
