A wall formwork suitable for intelligent construction of shafts

Abstract

The invention discloses a wall building formwork applicable to intelligent construction of a vertical shaft. The outer surface of the formwork is coated with a Teflon coating; a main body comprises a core frame cylinder, curve sliding rails and segmental sliding forms, and formwork supporting and releasing actions of the segmental sliding forms are realized by the aid of radial contraction indirectly produced by vertical traveling of the segmental sliding forms in the longitudinal direction through the curve sliding rails. Leveling and centering of the formwork are subjected to servo adjustment by corresponding hydraulic oil cylinders after pose determination by sensors, and circularity regulation is not needed. The formwork has basic function of a concrete pouring envelop structure as well as capacity of monitoring and evaluating the quality and an evolution process of cast-in-place concrete by means of setting of pressure, temperature, moisture and ultrasonic measurement points on the outer surface of the formwork. The formwork has the characteristics of being reasonable in structure, reliable in work, quick in action and capable of performing automatic centering and leveling and evaluating the pouring quality of the concrete in real time, and realizes intelligence of the construction process of the vertical shaft.

AI Technical Summary

Problems solved by technology

However, as the construction depth of shaft shafts in my country extends to 800-1200 m, and the excavation diameter reaches 9.0-15.0 m, the current formwork structure and construction technology are difficult to meet the actual engineering needs.

It is mainly manifested in the insufficient height of the formwork section (usually <5 m); the difficulty of hanging and fixing and the complicated adjustment operation; the difficulty of leveling and centering the vertical formwork and the single function, etc.

In addition, the main disadvantages of the traditional integral metal formwork in the application of shaft wall concrete pouring engineering include heavy weight, high friction with concrete (high demoulding resistance) and easy corrosion.

Although the hydraulic cylinder has been actuated in the supporting and demoulding process, it still requires a large number of personnel to make auxiliary adjustments, and the formwork can only be used as an enclosure structure for concrete pouring, and its function is relatively single

Therefore, no matter in terms of materials, structural types or functional systems, the traditional integral metal formwork does not involve any information and control technology at all, and cannot meet the requirements of intelligent construction of shafts

Therefore, it is urgent to re-develop a new type of intelligent wall formwork from the aspects of formwork material, structure type, automatic adjustment and multifunctional functions to solve the problems of unevaluable quality of well wall pouring, high labor intensity of workers, harsh working environment, and high safety risks. question
