Description

Technical Field

[0001] This application relates to the field of concrete construction and curing technology, and in particular to an automatic spraying device for concrete curing in slipform applications. Background Technology

[0002] If concrete is not cured promptly after pouring, dehydration will occur, preventing the cement particles that have formed cementitious granules from fully hydrating. This prevents them from transforming into stable crystals and results in insufficient bonding strength, leading to flaking and peeling of the concrete surface. Later, when the concrete reaches sufficient strength, the lack of moisture will cause significant shrinkage, resulting in drying shrinkage cracks. Therefore, proper curing of concrete after pouring is crucial. Curing should begin immediately after concrete sets, and dry-hardened concrete should be cured immediately after pouring.

[0003] Currently, the most common maintenance method is manual watering. However, due to the unique nature of slipform concrete construction in vertical shafts, manual watering is labor-intensive and struggles to guarantee uniform water coverage and flow, making conventional methods inadequate. While some automatic sprinkler systems use steel wire ropes to secure the pipes, this method is not only cumbersome to install, requiring significant time and manpower for winding, knotting, and adjusting, but also difficult to dismantle after construction. The wire ropes easily become entangled with the main pipes, increasing dismantling difficulty and time costs. Furthermore, the effectiveness of the wire ropes is greatly affected by human intervention, making it difficult to guarantee the stability of the pipeline in complex construction environments. This can lead to pipe leaks due to loosening or displacement, uneven sprinkler spraying, and other problems, severely impacting concrete curing quality and construction progress. Utility Model Content

[0004] To address or partially address the problems existing in the related technologies, this application provides an automatic spraying device for concrete curing in slipform construction. This device is based on a detachable support frame with a water supply pipe installed in a fixed position, and achieves curing of the poured surface by automatically spraying water through rotating nozzles.

[0005] The first aspect of this application provides an automatic spraying device for concrete curing in slipform construction, comprising: a main water supply pipe, a fixed bracket for positioning and connecting the main water supply pipe to the wall of a vertical shaft, a curing water pipe arranged around the railing of the slipform platform, a water supply branch pipe for connecting the curing water pipe and the main water supply pipe, and automatic rotating nozzles installed at intervals on the curing water pipe. A flow control valve is installed on the main water supply pipe, and the main water supply pipe is connected to a water storage tank based on a water pump.

[0006] The fixed support includes a positioning seat, a limiting clamp, and an adjusting bolt. The limiting clamp is clamped on the main water supply pipe and is fixed and adjusted based on the adjusting bolt. The limiting clamp is connected to the shaft wall through the positioning seat.

[0007] The positioning seat has an "L-shaped" structure, with an anti-slip pad on the side that contacts the shaft wall, and multiple mounting holes spaced apart on the positioning seat.

[0008] The limiting clamp includes two arc-shaped plates with their ends hinged together. The other end of the arc-shaped plates is provided with a through hole that is coaxial with the top and bottom. The two arc-shaped plates are fastened together by adjusting bolts provided in the through holes.

[0009] The fixed bracket also includes a locking nut, which is used to tighten the adjusting bolt in the reverse direction. The technical solution provided in this application may have the following beneficial effects:

[0010] This application provides an automatic spraying device for concrete curing in slipform applications. The device allows for rapid installation and disassembly of the main water supply pipe via a detachable fixing bracket, effectively reducing the installation workload for construction workers.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0021] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 The automatic spraying device for curing concrete using slipform construction shown includes: a main water supply pipe 3, a fixed support 5, a curing water pipe 7, a water supply branch pipe 6, and an automatic rotating nozzle 8. The main water supply pipe 3 is connected to a water storage tank 2 based on a water pump 1, and a flow control valve 4 is installed on the main water supply pipe 3.

[0023] The fixed bracket 5 is used to position and connect the main water supply pipe 3 to the shaft wall, such as... Figure 2 As shown, the fixed bracket 5 includes a positioning seat 51, a limiting clamp 52, and an adjusting bolt 53. The positioning seat 51 has an "L-shaped" structure, with an anti-slip pad 54 on the side in contact with the shaft wall. Multiple mounting holes are spaced apart on the positioning seat, and bolts are used to fix the positioning seat 51 to the shaft wall. Since the shaft wall may be uneven or have construction errors, multiple mounting holes allow for selection of appropriate hole positions to match with expansion bolts, ensuring the positioning seat can be accurately installed in the predetermined position. When it is necessary to fix water mains 3 with different outer diameters, the relative position of the limiting clamp and the positioning seat can be adjusted through the mounting holes to ensure the limiting clamp tightly wraps around the water main 3.

[0024] The limiting clamp 52 is clamped onto the main water supply pipe 3 and includes two arc-shaped plates. The ends of the arc-shaped plates are hinged to each other through a rotating connecting part 55, and the other end is provided with a through hole that is coaxial with the top and bottom. The two arc-shaped plates are fastened together by adjusting bolts 53 provided in the through holes and are fixed and adjusted based on the adjusting bolts 53. The adjusting bolts 53 pass through the copper buckle, the positioning seat 51 and are connected to the vertical shaft wall. The locking nut 56 is installed on the outside of the positioning seat 51 and is used to lock the adjusting bolts 53 in the reverse direction.

[0025] A ring of curing water pipes 7 is arranged on the railing near the concrete of the finishing platform. A water supply branch pipe 6 is set up to connect the curing water pipes 7 and the main water supply pipe 3. Multiple automatic rotating nozzles 8 are installed at intervals on the curing water pipes 7.

[0026] In use, a water storage tank 2 is set at the top platform of the shaft. A water pump 1 is used to pump the curing water into the main water supply pipe 3. The water supply pipe 3 is then transported along the shaft wall to the shaft platform. Construction personnel control the spraying pressure and volume of the curing water by adjusting the flow control valve 4. The main water supply pipe 3 is connected to the flow control valve 4. Rubber hoses of different diameters are selected according to site requirements. The flow control valve 4 is a wireless electric flow control valve. The curing water pipe 7 is arranged on the fence of the bottom finishing platform of the slipform near the concrete surface. According to the arrangement of the finishing platform, a water supply branch pipe 6 is branched from the main water supply pipe 3. The water supply branch pipe 6 is connected to the curing water pipe 7. An automatic rotating nozzle 8 is set on the curing water pipe 7 according to the shape of the poured body. After the curing water reaches the curing water pipe 7, the water pressure enables the end to automatically rotate and spray the curing water onto the concrete surface.

[0027] During slipform concrete construction, there is no need to move the pipeline. The concrete curing process can be controlled manually by controlling the flow control valve 4 according to the on-site pouring situation.
