Description

Technical Field

[0001] The present application relates to the technical field of water conservancy and hydropower engineering, and in particular to a box-type inclined well sliding form locking device. Background Art

[0002] Inclined shaft construction is a common practice in many water conservancy projects, particularly pumped-storage projects. This is known for its high difficulty and safety risks, making it a bottleneck and bottleneck in hydropower construction. Inclined shaft slipform locking is an essential component of shaft construction, and its design and construction are crucial for ensuring the quality and safety of inclined shaft construction. It ensures the stability and safety of the slipform during concrete pouring. Currently, inclined shaft slipform locking in China typically uses locking beams. However, with the vigorous development of my country's hydropower resources, the proliferation of underground hydropower station projects, and the accelerated construction schedule, traditional locking beams are no longer able to meet construction deadlines. Due to the large size and weight of inclined shaft locking beams, ensuring their safe construction requires the erection of a large steel structure as an operating platform. This requires significant labor and takes a long time to set up. Furthermore, the large size and weight of the locking beams make it impossible to mechanically lift them into position during construction. Manual labor is required to slowly move the beams into position and then reinforce them. The large size and weight of the locking beams, coupled with the high-altitude construction, pose significant safety risks. Therefore, how to replace the locking beam, speed up the construction progress and improve construction safety is particularly important and urgent. Utility Model Content

[0003] In order to solve or partially solve the problems existing in the related technology, the present application provides a box-type inclined shaft sliding form locking device, which can improve construction efficiency, speed up construction progress and reduce construction risks.

[0004] The present application discloses a box-type inclined shaft sliding form locking device, comprising a box body, the bottom of which is provided with a through hole;

[0005] and round steel, connecting stiffeners, locking anchor plates, anchor pads, and slipform climbing strands;

[0006] Among them, round steel is fixedly connected on both sides of the box body, an anchor plate is set at the bottom through hole of the box body, a locking anchor plate is connected on the anchor plate, a sliding form climbing steel strand is connected inside the locking anchor plate, and the sliding form climbing steel strand passes through the locking anchor plate, the anchor plate and the through hole.

[0007] Optionally, an anchor plate clip is provided between the locking anchor plate and the slipform climbing steel strand.

[0008] Optionally, the box body is formed by welding four steel plates in pairs. A transverse connecting plate is arranged in the middle thereof. Connecting stiffening plates are arranged on both suspended sides thereof to connect and fix the side walls with the transverse connecting plate, as well as the top plate and the bottom plate. The round steel is welded and fixed on the side plate.

[0009] Optionally, a cross-shaped steel frame is welded and arranged around the through hole. The cross-shaped steel frame is welded and fixed to the bottom plate of the box body.

[0026] and round steel 2, connecting stiffening plate 4, locking anchor plate 5, anchor backing plate 6, slip form climbing steel strand 8;

[0027] Wherein, round steel 2 is fixedly connected to both sides of the box body 3, and the round steel 2 extends out of the top of the box body 3 and is fixedly connected to the anchor rod 1 anchored in the upper bend bedrock at the upper end of the inclined shaft. An anchor backing plate 6 is arranged at the through hole at the bottom of the box body 3. A locking anchor plate 5 is connected to the anchor backing plate 6. A slip form climbing steel strand 8 is connected inside the locking anchor plate 5, and the slip form climbing steel strand 8 passes through the locking anchor plate 5, the anchor backing plate 6 and the through hole.

[0028] This device replaces the original locking beam by adopting a box body structure. At the same time, other parts except the necessary connection parts are removed. After using this device, the construction difficulty is greatly reduced. Since the volume and weight of this device are reduced, there is no need to set up an operation platform for the locking beam, and a crane can be used for construction, thus shortening the construction time and accelerating the construction progress. At the same time, due to the relatively fast construction speed and the reduced weight, personnel do not need to work at high altitude for a long time, greatly reducing the construction safety risk.

The inclined shaft slip form locking device is optimized, reducing the construction difficulty of the inclined shaft slip form locking device, improving the construction efficiency, accelerating the construction progress, reducing the construction risk, and having high popularization and application value.

[0029] In one embodiment, an anchor plate clip 7 is arranged between the locking anchor plate 5 and the slip form climbing steel strand 8 for locking and fixing the slip form climbing steel strand 8.

[0030] In one embodiment, the structure of a box body 3 is formed by welding two by two of four steel plates. A transverse connecting plate is arranged in the middle thereof.

The cross-shaped steel frame is welded and fixed to the bottom plate of the box body 3. One side of the cross-shaped steel frame is connected to the side plate, and the other side of the cross-shaped steel frame is connected to the connecting stiffening plate 4. In this way, the strength is improved through the cross-shaped steel frame.

[0032] In one embodiment, for the convenience of locking, the locking anchor plate 5 is arranged in a disc shape, and at least four slip form climbing steel strands 8 are arranged and fixed to the locking anchor plate 5 through the anchor plate clip 7.

[0033] In this application, the anchor rod 1 with its upper end of the inclined shaft anchored in the bedrock of the upper bend section is constructed and completed during the excavation stage. The box body 3 and the connecting stiffening plate 4 can be prefabricated and processed in advance. When the lining concrete construction of the inclined shaft is carried out after the excavation of the inclined shaft is completed, a crane is used for the installation work of the box body 3. The box body 3 is welded and reinforced with the round steel 2 and the anchor rod 1 with its upper end of the inclined shaft anchored in the bedrock of the upper bend section. After the box body 3 is fixed firmly, the locking anchor plate 5, the anchor backing plate 6, the anchor plate clip 7, and the slip form climbing steel strand 8 are installed.
