Embodiment

[0044] Such as Figure 1-2 As shown, this embodiment provides a shaft lining device, which includes a lifting device 1, two suspension anchor devices 2, and a suspension plate formwork device 3. The lifting device 1 includes a gantry crane, and the gantry crane is located above the shaft. Two The suspension anchoring device 2 is symmetrically fixed around the shaft mouth, and the suspension anchoring device 2 is provided with a suspension wire rope and a rope clamp;

[0045] Such as Figure 1-3 As shown, the hanging plate formwork device 3 includes an upper hanging plate 9, a column 4 and an operation platform 10, and the two ends of the column 4 are fixedly connected with the upper hanging plate 9 and the operating platform 10 respectively, specifically, the two ends of the column 4 are connected with the upper hanging plate 9 respectively. Connect with the operating platform 10 bolts;

[0046] Such as Figure 3-4 As shown, the upper hanging plate 9 is provided with liftin...

Abstract

The invention discloses a vertical shaft lining construction method. The vertical shaft lining construction method is characterized in that a laying step, a binding step, a lifting and suspending step, a mold erecting step, a blanking and mold entering step, a demolding step and a separation step in the vertical shaft lining construction method are completed through a hanging scaffold formwork device, a lifting device and a suspension anchoring device. During the construction process, by means of the vertical shaft lining construction method, vertical shaft lining construction work can be completed simply, rapidly and safely, time, manpower and material resources are saved, and the working efficiency and the construction progress are improved.

Description

technical field [0001] The patent of the present invention relates to the field of tunnel and underground engineering construction, in particular to a shaft lining construction method. Background technique [0002] In the prior art, lining is exactly to prevent surrounding rock from deforming or collapsing, and is a permanent support structure built with reinforced concrete and other materials along the periphery of the tunnel body. In the construction process of deep shaft lining concrete structures such as mountain and water conservancy projects, the bracket method is generally used for construction. [0003] The support method in the prior art is to set up scaffolding at certain intervals in the shaft as the inner support of the mold, and use small pieces of steel formwork splicing to form an inner mold for shaft lining construction. The support method lining has extremely high requirements on the site and is suitable for For shafts with small depth, although the investm...
