Description

A dam surface spraying maintenance device

Technical Field

The utility model relates to the technical field of water conservancy projects, in particular to a dam surface spraying and maintenance device.

Background Art

The purpose of dam surface maintenance is to ensure that the concrete structure can achieve the strength and durability required by the design after construction. Through maintenance, the temperature of concrete can be effectively controlled, temperature cracks can be prevented during the curing process, and the overall performance of concrete can be improved. In addition, dam surface maintenance can also help slow down the evaporation rate of concrete water, maintain appropriate humidity, and be conducive to the early strength development of concrete. Through reasonable dam surface maintenance, the risk of concrete surface cracking can be reduced, construction defects can be reduced, and the safety and long-term stable operation of the dam structure can be ensured.

There are some problems in the current dam surface maintenance, mainly reflected in the use of artificial sprinkling of water at irregular intervals for concrete maintenance. This method has the following shortcomings:

1. It is difficult to maintain a stable low temperature state of concrete by artificial intermittent watering, which causes the temperature to rise quickly and affects the curing effect;

2. Artificial watering requires workers to walk on the dam surface, which is easy to leave footprints on the concrete surface, causing some quality defects and affecting the overall quality of the dam surface concrete;

3. The use of artificial sprinkling water at irregular intervals makes it impossible to maintain uniform and continuous maintenance, resulting in poor temperature control maintenance effect, requiring later defect processing, which increases cost investment.

Utility Model Content

In order to solve these problems, the utility model provides a dam surface spraying maintenance device, which aims to improve the effect of concrete maintenance, reduce quality defects, and reduce the cost of later maintenance. The following technical solutions are adopted:

A dam surface spray maintenance device includes a device body, a spray clamp, and a water inlet pipe. The device body is a frame structure composed of multiple spray pipes. One end of the device body is connected to the water inlet pipe through a valve. The bottom of the spray pipe is evenly distributed with multiple spray holes along the axial direction. A spray clamp is provided at the position of each spray hole on the spray pipe. The spray clamp consists of two arc-shaped clips, wherein the first clip is a grid-like structure and the second clip is a dense piece. When in use, the spray clamp is clamped at the position of the spray hole on the spray pipe, and the first clip and the spray hole are on the same side.

By adopting the above technical solution, the spray pipe is used to form the frame structure of the main body of the device and its size is matched with the dam surface, so that it can better adapt to the specific size and shape of the dam. At the same time, a spray hole is opened at the bottom of the pipe, that is, on the side facing the dam surface, which can ensure that the spray maintenance device effectively covers the entire dam surface and improve the maintenance effect. The first clip on the same side of the spray hole is in a grid shape and covers the spray hole. The grid-shaped clip disperses the water flow and breaks it into small water droplets when the water flows out, thereby achieving uniform spraying.

Furthermore, the curvature of the first clamp and the second clamp is concentric with the circular contour of the cross section of the spray pipe.

By adopting the above technical solution, the spray clamp can be rotated directly around the pipe more conveniently, and the opening and closing state of the spray hole can be controlled by rotating the clamp. The dense sheet structure of the second clamp on the other side of the spray clamp blocks some water outlets, which can increase the path of water flow, thereby increasing the water pressure through the spray clamp. In this way, the water flow can be distributed more evenly between different areas of the dam surface, ensuring that the effect of spray maintenance is more consistent and effective. In this case, the spray clamp plays a role in water flow control and regulation, which helps to optimize the water flow distribution according to specific maintenance needs and improve the spray effect of the device.

Furthermore, a sealing ring is provided at the edge of the spray hole.

By adopting the above technical solution, a sealing ring is arranged around the spray hole. When the dense sheet rotates to the spray hole, the sealing ring can provide better sealing performance to prevent water from leaking from the gap between the clip and the pipe, thereby ensuring that the water flow is accurately and orderly sprayed onto the concrete surface that needs to be cured during spray curing.

Furthermore, the size of the device body matches the size of the maintenance dam surface, and the pipe distance between the device body and the water inlet pipe is 50 cm.

Furthermore, the wall thickness of the spray pipe is 3 cm, and the diameter of the spray hole is 1.6 cm.

Furthermore, the spacing between the spray holes on the spray pipe is 2m.

In summary, this application includes the following beneficial technical effects:

The utility model matches the frame structure size of the device theme with the dam surface, and the spray holes are evenly opened at the bottom of the pipe to ensure uniform and comprehensive spray coverage, thereby improving the construction quality. The spray clamp is flexibly designed, and the water flow is accurately controlled by the rotation of the clamp, thereby achieving fine maintenance of the dam surface. At the same time, the water retaining design of the dense sheet improves the pressure and uniformity of the water flow, effectively reduces the surface temperature of the concrete, and reduces the occurrence of quality defects. The sealing ring design at the edge of the spray hole further ensures the accurate spraying of the water flow and enhances the stability and durability of the device. In summary, the dam surface spray maintenance device proposed by the utility model realizes comprehensive and efficient concrete maintenance, making the dam surface maintenance more convenient and efficient, while reducing maintenance costs and improving the overall project quality.

6 , preferably, in this embodiment, the curvature of the first clamping piece 4 and the second clamping piece 5 is concentric with the circular contour of the cross section of the spray pipe 1 .

6 , preferably, in this embodiment, a sealing ring 10 is provided at the edge of the spray hole 2 .

Preferably, in this embodiment, the size of the device body matches the size of the maintenance dam surface, and the pipe distance between the device body and the water inlet pipe 9 is 50 cm.

Preferably, in the present embodiment, the wall thickness of the spray pipe 1 is 3 cm, and the diameter of the spray hole 2 is 1.6 cm.

Preferably, in this embodiment, the distance between the spray holes 2 on the spray pipe 1 is 2 m.

The working principle of this embodiment is to erect the frame structure of the device body consisting of the spray pipe 1 on the dam surface, reserve a 50cm pipe at one end for connecting the water inlet pipe 9 and set a valve 8 on the pipe, control the water inlet through the valve 8, introduce the water flow into the spray pipe 1, and spray it onto the dam surface through the spray hole 2. The first clip 4 of the spray clamp 3 on the same side of the spray hole 2 is in a grid shape and covers the spray hole 2. The grid-shaped clip plays a role in dispersing the water flow and breaking it into small water droplets when the water flows out, thereby achieving uniform spraying.

When the water pressure inside the water inlet pipe 9 or the main body of the device is insufficient, the opening and closing state of the spray hole 2 can be controlled by adjusting the clamping method of the spray clamp 3. By blocking some spray holes 2 through the dense sheet structure of the second clamp 5 on the other side of the spray clamp 3, the path through which the water flows can be increased, thereby increasing the water pressure. In this way, the water flow can be more evenly distributed between different areas of the dam surface, ensuring that the effect of spraying maintenance is more consistent and effective. At the same time, a circle of sealing rings 10 is set around the spray hole 2. When the second clamp 5 is adjusted to the position of the spray hole 2, the sealing ring 10 can provide better sealing performance to prevent water from leaking from the gap between the second clamp 5 and the spray pipe 1, ensuring that the water flow is accurately and orderly sprayed onto the concrete surface that needs to be maintained during spraying maintenance.
