Description

Technical Field

[0001] This utility model relates to the field of cantilever beam maintenance and construction technology, specifically to a water spraying maintenance device for continuous beam cantilever construction. Background Technology

[0002] The purpose of concrete curing is to keep newly poured concrete in a constant temperature and humidity environment to promote the hydration reaction of cement-based materials, so that the strength, hardness and other properties of the concrete block can be fully developed to reach the best state. Preventing the loss of moisture from the concrete surface is one of the important objectives of concrete curing. Therefore, during the curing process, it is necessary to continuously replenish the surface of the concrete and control the ambient temperature to keep the concrete in a suitable humid environment.

[0003] In the existing continuous beam cantilever construction process, concrete curing is mostly carried out by covering the top slab and the inside of the box girder with geotextile and manually sprinkling water. Traditional water sprinkling curing uses a water pump to pump curing water to the bridge deck through pipelines, supplemented by manual watering. During the curing period, watering needs to be carried out multiple times at irregular intervals depending on the temperature and sunshine conditions.

[0004] However, if manual curing is used, it is difficult to control the quality of curing of the bottom plate, web plate and flange plate when the formwork moves to the next section. It is difficult to ensure that the bottom plate and web plate are properly cured, which may lead to excessive water loss during curing. This may cause excessive temperature difference between the inside and outside of the concrete, resulting in temperature stress and affecting the quality of the concrete. Utility Model Content

[0005] This application provides a water spraying and curing device for cantilever construction of continuous beams, which can solve the problem that in the prior art, if manual curing is used, it is difficult to control the quality of curing of the bottom plate, web plate and flange plate when the hanging basket moves to the next segment, making it difficult to fully ensure that the bottom plate and web plate are properly cured. This may lead to excessive water loss during curing, which may easily cause excessive temperature difference between the inside and outside of the concrete, thereby generating temperature stress and affecting the quality of the concrete.

[0006] In a first aspect, embodiments of this application provide a water spraying and curing device for cantilever construction of continuous beams, comprising: The maintenance water tank is equipped with a water pump. At least one spray pipe is provided for installation on the beam and for connection to the outer guide beam and the rear lower cross beam of the hanging basket. The inlet section of the spray pipe is connected to the water pump, and the outlet section of the spray pipe extends from the top surface of the beam to the bottom plate and the web. A timing control mechanism, electrically connected to the water pump, is used to turn on the water pump at a set period.

[0007] In one embodiment, the water outlet section includes: The first water outlet branch is connected at its end to the water inlet section. The first water outlet branch is used to be fixed on the outer guide beam of the hanging basket. The first water outlet branch is used to extend through the drain hole of the beam to the web. The second water outlet branch is connected at its end to the water inlet section. The second water outlet branch is used to fix the lower rear crossbeam. The second water outlet branch passes through the top surface of the beam and extends beyond the beam to the bottom plate.

[0008] In one embodiment, the first outlet branch includes: The first conveying section has one end connected to the water inlet section; The first curing section, which is connected to the other end of the first conveying section, is installed at the web plate and is used to cure the web plate.

[0009] In one embodiment, the first curing section is provided with a plurality of spaced-apart swing nozzles.

[0010] In one embodiment, the second outlet branch includes: The second curing section is connected at one end to the water inlet section and is set along the top surface of the beam body for curing the top surface of the beam body; The second conveying section has one end connected to the other end of the second curing section; The third curing section is connected to the other end of the second conveying section and is installed at the bottom plate to cure the bottom plate.

[0011] In one embodiment, both the second curing section and the third curing section are equipped with rotating nozzles.

[0012] In one embodiment, a T-shaped pipe is provided at the end of the water inlet section away from the maintenance water tank, and the other two ports of the T-shaped pipe are respectively connected to the ends of the first water outlet branch and the second water outlet branch.

[0013] In one embodiment, both the maintenance water tank and the timing control mechanism are mounted on the beam.

[0014] In one embodiment, the timing control mechanism is connected to the water pump via a connecting cable.

[0015] In one embodiment, the spray pipe includes multiple pipe units, each pipe unit having a front connector and a rear connector, the front connector being used to connect to the rear connector of any pipe unit.

[0016] The beneficial effects of the technical solutions provided in this application include: When using the water spraying curing device for continuous beam cantilever construction, at least one spray pipe is installed on the beam and connected to the outer guide beam and rear lower crossbeam of the formwork. The inlet section of the spray pipe is connected to a water pump, and the outlet section extends from the top surface of the beam to the bottom slab and web. A timing control mechanism is electrically connected to the water pump to activate the pump at a set interval. Because the outlet section of the spray pipe extends from the top surface of the beam to the bottom slab and web, it can simultaneously cure the top surface, bottom slab, and web of the beam. The timing control mechanism allows the water pump to be activated at a set interval, reducing manual labor while improving curing quality. This solves the problem in existing technologies where, with manual curing, the curing quality of the bottom slab, web, and flanges is difficult to control when the formwork moves to the next segment, making it difficult to ensure adequate curing of the bottom slab and web. This can lead to excessive water loss during curing, potentially causing excessive temperature differences between the inside and outside of the concrete, resulting in temperature stress and affecting concrete quality.

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0023] This application provides a water-sprinkling curing device for cantilever construction of continuous beams. It can solve the problem that in the prior art, if manual curing is used, it is difficult to control the curing quality of the bottom plate, web plate and flange plate when the formwork moves to the next segment. It is difficult to ensure that the bottom plate and web plate are properly cured, which may lead to excessive water loss during curing. This may cause excessive temperature difference between the inside and outside of the concrete, resulting in temperature stress and affecting the quality of the concrete.

[0024] like Figure 1 and Figure 2 As shown, this application provides a water spraying and curing device for cantilever construction of continuous beams, which includes: Maintenance water tank 1, which is equipped with water pump 2 inside; At least one spray pipe 3 is installed on the beam 4 and is used to connect with the outer guide beam and the rear lower cross beam of the hanging basket. The water inlet section of the spray pipe 3 is connected to the water pump 2, and the water outlet section of the spray pipe 3 extends from the top surface of the beam 4 to the bottom plate and the web plate. The timing control mechanism 5 is electrically connected to the water pump 2 and is used to turn on the water pump 2 at a set cycle.

[0025] When using the water spraying and curing device for continuous beam cantilever construction, at least one spray pipe 3 is installed on the beam 4 and connected to the outer guide beam and the rear lower cross beam of the hanging basket. The inlet section of the spray pipe 3 is connected to the water pump 2, and the outlet section of the spray pipe 3 extends from the top surface of the beam 4 to the bottom plate and web plate. The timing control mechanism 5 is electrically connected to the water pump 2 and is used to turn on the water pump 2 at a set cycle. Since the outlet section of the spray pipe 3 extends from the top surface of the beam 4 to the bottom plate and web plate, it can simultaneously satisfy the curing of the top surface, bottom plate and web plate of the beam 4. The timing control mechanism 5 can turn on the water pump 2 at a set cycle, which reduces manual labor and improves the curing quality. This solves the problem in the prior art that if manual curing is used, it is difficult to control the curing quality of the bottom plate, web plate and flange plate when the hanging basket moves to the next section. It is difficult to ensure that the bottom plate and web plate are fully cured, which may lead to excessive water loss during curing. This may easily cause excessive temperature difference between the inside and outside of the concrete, thereby generating temperature stress and affecting the quality of the concrete.

[0026] In this example, the outer guide beam and the lower rear crossbeam of the hanging basket are both steel structural components used in continuous beam cantilever construction. Fixing the sprinkler pipe 3 to the outer guide beam and the lower rear crossbeam of the hanging basket is beneficial to the stable operation of the curing process.

[0027] In this example, there are two sprinkler pipes 3, which are respectively installed on both sides of the beam 4 along the transverse direction of the bridge. The sprinkler pipes 3 are installed in the pre-embedded steel bars of the protective wall on the beam surface.

[0028] In this example, pump 2 is a 65DL32-15x4 with a flow rate of 32 m³ / h, a head of 60 m, and a motor power of 11 kW.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, in some optional embodiments, the outlet section includes: The first water outlet branch 31 is connected to the water inlet section at its end. The first water outlet branch 31 is used to fix on the outer guide beam of the hanging basket. The first water outlet branch 31 is used to extend through the drain hole of the beam 4 to the web. The second water outlet branch 32 is connected to the water inlet section at its end. The second water outlet branch 32 is used to fix it on the rear lower crossbeam. The second water outlet branch 32 passes through the top surface of the beam 4 and extends out of the beam 4 to the bottom plate.

[0030] In this embodiment, the structure of the water outlet section is specifically described. The water outlet section includes a first water outlet branch 31 and a second water outlet branch 32. The end of the first water outlet branch 31 is connected to the water inlet section. The first water outlet branch 31 is used to fix on the outer guide beam of the hanging basket.

The second water outlet branch 32 is used to fix on the rear lower crossbeam. The second water outlet branch 32 passes through the top surface of the beam 4 and extends beyond the beam 4 to the bottom plate. This facilitates the simultaneous maintenance of the top surface, bottom plate and web of the beam 4. The structure is simple and easy to manufacture.

[0031] like Figure 1 and Figure 3 As shown, in some optional embodiments, the first water outlet branch 31 includes: The first conveying section 311 has one end connected to the water inlet section; The first curing section 312 is connected to the other end of the first conveying section 311 and is used to be installed at the web plate for curing the web plate.

[0032] In this embodiment, the specific structure of the first water outlet branch 31 is described. The first water outlet branch 31 includes a first conveying section 311 and a first curing section 312. One end of the first conveying section 311 is connected to the water inlet section, and the first curing section 312 is connected to the other end of the first conveying section 311. It is used to be installed at the web plate for curing the web plate. The structure is simple and easy to manufacture.

[0033] In this example, the first maintenance section 312 is divided into two parts. One part is arranged along the longitudinal direction of the bridge and is connected to the first conveying section 311. The second part extends into the inner side of the beam 4 along the transverse direction of the bridge and is used to maintain the web.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, in some optional embodiments, the first curing section 312 is provided with a plurality of spaced-apart swing nozzles 6.

[0035] In this embodiment, a plurality of spaced-apart swing nozzles 6 are provided on the first curing section 312 for swinging water spraying, which can increase the curing area.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, in some optional embodiments, the second water outlet branch 32 includes: The second maintenance section 321 is connected to the water inlet section at one end and is set along the top surface of the beam 4 for maintaining the top surface of the beam 4. The second conveying section 322 is connected at one end to the other end of the second maintenance section 321; The third curing section 323 is connected to the other end of the second conveying section 322 and is used to be installed at the bottom plate for curing the bottom plate.

[0037] In this embodiment, the specific structure of the second water outlet branch 32 is described. The second water outlet branch 32 includes a second curing section 321, a second conveying section 322, and a third curing section 323. One end of the second curing section 321 is connected to the water inlet section and is set along the top surface of the beam 4 for curing the top surface of the beam 4. One end of the second conveying section 322 is connected to the other end of the second curing section 321. The third curing section 323 is connected to the other end of the second conveying section 322 and is set at the bottom plate for curing the bottom plate. The structure is simple and easy to manufacture.

[0038] In this example, the second maintenance section 321 is arranged along the bridge direction and extends out of the beam 4. One end of the second conveying section 322 is connected to the end of the second maintenance section 321 that extends out of the beam 4. The third maintenance section 323 is arranged along the bridge direction.

[0039] like Figure 1 , Figure 2 and Figure 3As shown, in some optional embodiments, both the second curing section 321 and the third curing section 323 are equipped with rotating nozzles 7.

[0040] In this embodiment, rotating nozzles 7 are provided on both the second curing section 321 and the third curing section 323 for rotating water spraying, which can increase the curing area.

[0041] In this example, the working principle of the oscillating nozzle 6 and the rotating nozzle 7 is that the water pressure generated drives the gears inside the oscillating nozzle 6 and the rotating nozzle 7 to rotate, and the gears drive the nozzles outside the oscillating nozzle 6 and the rotating nozzle 7 to rotate, thereby completing the automatic rotating water spraying.

[0042] like Figure 1 As shown, in some optional embodiments, a three-way pipe 33 is provided at the end of the water inlet section away from the maintenance water tank 1, and the other two ports of the three-way pipe 33 are respectively connected to the ends of the first water outlet branch 31 and the second water outlet branch 32.

[0043] In this embodiment, a three-way pipe 33 is provided at the end of the water inlet section away from the maintenance water tank 1. The other two ports of the three-way pipe 33 are connected to the ends of the first water outlet branch 31 and the second water outlet branch 32, respectively, for easy connection.

[0044] like Figure 1 As shown, in some optional embodiments, both the maintenance water tank 1 and the timing control mechanism 5 are mounted on the beam 4.

[0045] In this embodiment, both the curing water tank 1 and the timing control mechanism 5 are installed on the beam 4 to reduce the length of the water inlet section of the spray pipe 3 and facilitate its use.

[0046] like Figure 1 As shown, in some optional embodiments, the timing control mechanism 5 is connected to the water pump 2 via a connecting cable 51.

[0047] In this embodiment, the timing control mechanism 5 is connected to the water pump 2 via a connecting cable 51, which is simple and has good stability.

[0048] In some alternative embodiments, the spray pipe 3 includes multiple pipe units, each pipe unit having a front connector and a rear connector, the front connector being used to connect to the rear connector of any pipe unit.

[0049] In this embodiment, the spray pipe 3 includes multiple pipe units, each of which is provided with a front connector and a rear connector. The front connector is used to connect to the rear connector of any pipe unit, which facilitates disassembly and assembly. When the construction section extends forward, it is convenient to remove the water outlet section of the spray pipe 3 and extend the spray pipe 3.

[0050] In summary, when using the water spraying and curing device for continuous beam cantilever construction, at least one spray pipe 3 is installed on the beam body 4 and connected to the outer guide beam and the rear lower cross beam of the hanging basket. The water inlet section of the spray pipe 3 is connected to the water pump 2, and the water outlet section of the spray pipe 3 extends from the top surface of the beam body 4 to the bottom plate and web plate. The timing control mechanism 5 is electrically connected to the water pump 2 and is used to turn on the water pump 2 at a set cycle. Since the water outlet section of the spray pipe 3 extends from the top surface of the beam 4 to the bottom slab and web, it can simultaneously satisfy the curing of the top surface, bottom slab and web of the beam 4. The water pump 2 can be turned on at a set cycle through the timing control mechanism 5, which reduces manual labor and improves the curing quality. It solves the problem that if manual curing is used in the existing technology, it is difficult to control the curing quality of the bottom slab, web and flange plates when the hanging basket moves to the next section. It is difficult to ensure that the bottom slab and web are fully cured, which may lead to the excessive loss of curing water and the potential for excessive temperature difference between the inside and outside of the concrete, thereby generating temperature stress and affecting the quality of the concrete.
