Embodiment 1

[0045] Embodiment 1, this embodiment aims to provide a shaft construction device, which is mainly used for the well wall pouring operation of the shaft. When supporting the existing formwork structure, the formwork needs to be re-centred every time it is used, which is difficult to ensure. Each template is on the same benchmark, resulting in the problem of deviation between the construction of the shaft wall and the standard requirements. This embodiment provides a shaft construction device.

[0046] like Figure 1-3 In this example, a shaft construction device is shown, including a center sleeve 1, a positioning mechanism, a telescopic mechanism and a combined template. In this embodiment, the center sleeve 1 is used as a fixed foundation, and its basic structure is a cylindrical structure, and a positioning structure is arranged on its upper part. , the lower part is arranged with a telescopic structure.

[0047] In the specific structure, the positioning mechanism includes...

Embodiment 2

[0068] Embodiment 2, this embodiment is basically the same as Embodiment 1, the difference is that this embodiment provides a positioning rod structure of another structure.

[0069] like Figure 10 The positioning rod 2 includes a sliding sleeve 26, a support rod 28 and a swing rod 27, the inner end of the swing rod 27 is hinged on the center sleeve 1, the sliding sleeve 26 is slidably sleeved on the center sleeve 1, and a lock is provided on its side. The two ends of the support rod 28 are respectively hinged to the side of the sliding sleeve and the middle of the swing rod, and the end of the swing rod is provided with a positioning block.

[0070] In this embodiment, the sliding sleeve is used to lift the pendulum rod synchronously, that is, the pendulum rod can be expanded synchronously, thereby realizing the purpose of rapid centering. Compared with the structure in Embodiment 1, the operation is simpler and the retracted state is smaller, which is convenient for Transf...

Embodiment 3

[0071] Embodiment 3, this embodiment is basically the same as Embodiment 1, the difference is that this embodiment provides another structure of the power telescopic rod structure.

[0072] In this embodiment, the power telescopic rod 5 includes an inner thread cylinder 16 , an outer thread cylinder 15 , an adjusting wire 17 and a stabilizing sleeve 18 . The opposite reverse thread, the two ends of the adjusting wire 17 are reverse threads, and are respectively screwed into the inner thread barrel and the outer thread barrel, the stabilizing sleeve 18 is slidably sleeved on the outside of the inner thread barrel, and is fixed on the center sleeve by a reinforcing rod On the rotating sleeve 20 on the upper part, the rotating sleeve 20 is rotatably sleeved on the center sleeve.

[0073] like Figure 5-6 It is shown in the figure that the stabilizing sleeve 18 and the inner threaded barrel 16 are sliding and non-rotatable sleeve structures, so as to avoid the rotation of the inn...

Abstract

The invention relates to a vertical shaft construction device and method.The device comprises a center sleeve, a positioning mechanism, a telescopic mechanism and a combined formwork, the positioning mechanism comprises a positioning rod, a positioning plate and an anchoring rod, and the anchoring rod is arranged in the center sleeve in a sleeved mode; the telescopic mechanism comprises a rotating seat and a power telescopic rod, the rotating seat is concentrically and rotatably sleeved on the central sleeve, one end of the power telescopic rod is fixed on the rotating seat, and the other end of the power telescopic rod is connected with the combined template; the combined formwork comprises a center plate, a front turning plate and a rear turning plate, the outer side face of the center plate is provided with a hinge seat and a grouting opening, the front turning plate and the rear turning plate are located on the front side and the rear side of the center plate respectively, the opposite sides of the two turning plates are hinged to the hinge seat, the inner side faces of the two turning plates can be locked when swinging inwards to the limiting position, and baffles are arranged at the ends of the two turning plates. The structure is novel, the multifunctional combined formwork is adopted as an outer formwork structure for pouring the inner wall of the shaft, the whole process is simple in construction, and the mold does not need to be replaced many times.

Description

technical field [0001] The invention relates to the technical field of shaft construction, in particular to a shaft construction device and method. Background technique [0002] At present, shafts are widely used in water conservancy projects, tunnel projects and other projects. During the excavation process of shafts, the [0003] It is usually excavated from the ground gradually downward. Based on this construction method, the construction should be carried out in layers and gradually downward, that is, excavation first, and then formwork pouring. [0004] In the process of shaft construction, formwork needs to be used to construct the shaft wall. Most of the existing formwork structures are multiple composite structures, and each formwork is an independent structure. During construction, each formwork needs to be constructed in a corresponding position, and the formwork It needs to be converted and used multiple times. For example, after the construction of the first tem...
