Abstract
Description
Technical Field
[0001] This utility model relates to the field of spray curing technology, and in particular to an automatic spray curing system for the construction of cantilevered sections of bridges using hanging baskets. Background Technology
[0002] Currently, long-span continuous beams are becoming increasingly common, and they are generally constructed using cantilever construction with formwork. The concrete used in these continuous beams is typically high-grade concrete, generating high temperatures during hydration. If the concrete is not properly cured in a timely manner, cracks will appear in the concrete segments of the continuous beam, which can have a serious impact on the bridge. Currently, curing methods for continuous beams using formwork typically only cover the surface of the top slab, the inner box girder web, and the top surface of the bottom slab, failing to provide comprehensive curing. Furthermore, curing methods generally involve covering the top and bottom slabs with geotextile and sprinkling water, while the inner box girder web is manually watered. These methods are also susceptible to interference from worker factors, making it impossible to guarantee continuous curing of the continuous beam segments at all times. Therefore, this invention proposes an automatic spray curing system for cantilever construction of bridge sections using formwork. Utility Model Content
[0003] The purpose of this utility model is to address the problems in the background technology where the maintenance of continuous beam hanging basket construction generally only involves maintaining the surface of the top slab, the inner box web, and the top surface of the bottom slab, which cannot achieve all-round maintenance of the continuous beam. Moreover, the maintenance generally adopts the method of covering the top surface of the top slab and the top surface of the bottom slab with geotextile and sprinkling water, while the inner box web is manually sprinkling water. At the same time, the maintenance process is subject to many interferences from workers, and it is impossible to guarantee that the continuous beam segments can be maintained at any time. Therefore, this utility model proposes an automatic spraying maintenance system for the construction of hanging baskets for cantilevered bridge sections.
[0004] The technical solution of this utility model is as follows: an automatic sprinkler curing system for cantilevered bridge sections using hanging baskets, comprising: a water tank located on the upper surface of the bridge top slab for storing water; top slab position water pipes disposed on both sides of the water tank, the top slab position water pipes being located on the upper surface of the bridge top slab, one end of the top slab position water pipes being connected to a flange plate curing water pipe located on one side of the bridge flange plate; an inner box curing water pipe disposed within the inner box of the bridge, the upper end of the inner box curing water pipe being connected to a curing switch, the upper end of the curing switch penetrating the bridge top slab and extending to communicate with the water tank; and a limiting component fixedly disposed on the upper surface of the bridge top slab for adjusting the length of the top slab position water pipes.
[0005] Optionally, the limiting component includes a set of support rods fixedly installed on the upper surface of the bridge top plate. A guide rod is fixedly installed at the upper end of the support rod. A set of collars is movably sleeved on the outer wall of the guide rod. A limiting bolt is threaded through the collar. A retaining ring for stably clamping the water pipe at the top plate position is fixedly installed on the outer wall of the guide rod.
[0006] Optionally, a pre-drilled hole for the top plate position is provided on the upper surface of the bridge top plate.
[0007] Optionally, a maintenance nozzle is connected to the flange plate maintenance water pipe and the inner box maintenance water pipe.
[0008] Optionally, a hanging basket is installed on the upper surface of the bridge top plate.
[0009] Optionally, a T-junction is provided at the connection between the water tank and the water pipe at the top plate position and the maintenance water pipe in the inner tank.
[0010] Optionally, a flexible hose is provided to connect the water pipes at the top plate location.
[0011] In summary, this application includes at least one of the following beneficial technical effects:
[0012] This utility model uses a water pump to transport water stored in the water tank to the water pipes at the top plate, the flange plate, and the inner tank, and sprays the water onto the cantilevered section of the bridge through a maintenance nozzle. It also uses a maintenance switch to achieve remote control. It has the advantages of simple structure, convenient installation, easy operation, strong practicality, low cost, and high construction efficiency.
[0013] Furthermore, by rotating the limiting bolt to adjust the position of the collar, the collar drives the retaining ring to move, and the retaining ring drives the water pipe at the top plate position to move, which can adjust the length of the water pipe at the top plate position, thus making it suitable for bridge cantilever sections of different lengths and improving the convenience of spray curing.

[0027] Example
[0028] like Figures 1 to 3As shown, this utility model proposes an automatic sprinkler curing system for the construction of a cantilevered bridge section using a formwork system. It includes a water tank 1 located on the upper surface of the bridge top slab for storing water, and the water tank 1 is equipped with a water pump to facilitate the delivery of the stored water. Water pipes 2 are located on both sides of the water tank 1 at the top slab position, and each water pipe 2 has two sections. One end of each water pipe 2 is connected to a flange plate curing water pipe 3, which is designed according to the external shape of the cantilevered bridge section. The water protection pipe 3 is located on one side of the bridge flange plate and is used for spraying and curing the bridge flange plate. The inner box curing water pipe 4 is installed in the inner box of the bridge and is connected to the water pipe 2 at the top plate position. The upper end of the inner box curing water pipe 4 is connected to the curing switch 5. The upper end of the curing switch 5 passes through the bridge top plate and extends to the water tank 1, and is used to control the spraying switch. The limiting component 9 is fixedly installed on the upper surface of the bridge top plate for adjusting the length of the water pipe 2 at the top plate position. It can adjust the length of the water pipe 2 at the top plate position according to the bridge, increasing its applicability.
[0029] like Figure 2 and Figure 4 As shown, the limiting component 9 includes a set of support rods 91 fixedly installed on the upper surface of the bridge top plate. A guide rod 92 is fixedly installed at the upper end of the support rod 91 to stably support the guide rod 92. A set of collars 93 are movably sleeved on the outer wall of the guide rod 92 to facilitate stable guidance of the collars 93. A limiting bolt 94 is threaded through the collar 93 to facilitate limiting the collar 93 and adjusting the position of the collar 93. A retaining ring 95 is fixedly installed on the outer wall of the guide rod 92 to stably engage the water pipe 2 at the top plate position, which facilitates support of the water pipe 2 at the top plate position and also facilitates adjustment of the length of the water pipe 2 at the top plate position.
[0030] like Figure 3 As shown, a pre-reserved hole 6 for the top plate position is provided on the upper surface of the bridge top plate to facilitate the connection between the water tank 1 and the water pipe 2 at the top plate position and the maintenance water pipe 4 in the inner tank.
[0031] like Figures 1 to 3 As shown, the flange plate curing water pipe 3 and the inner box curing water pipe 4 are connected to the curing nozzle 7, which facilitates uniform spraying and curing of the cantilever section of the bridge.
[0032] Furthermore, a hanging basket 8 is installed on the upper surface of the bridge top plate to provide support for the water pipe 2 at the top plate position, making the installation of the water pipe 2 at the top plate position more stable.
[0033] Secondly, a T-junction is installed at the connection between the water tank 1 and the water pipe 2 at the top plate position and the maintenance water pipe 4 in the inner tank, so as to facilitate the transmission of the stored water in the water tank 1 to the inside of the water pipe 2 at the top plate position and the maintenance water pipe 4 in the inner tank for spraying onto the cantilevered section of the bridge.
[0034] In addition, a flexible hose 10 is installed between the water pipes 2 at the top plate position to facilitate the adjustment of the length of the water pipes 2 at the top plate position during movement.
[0035] The working principle of this embodiment is as follows: During installation, a pre-drilled hole 6 is reserved on the top plate of the bridge cantilever section, and the water tank 1 is installed directly above the pre-drilled hole 6 on the top plate. The upper end of the inner tank maintenance water pipe 4 is connected to the maintenance switch 5. Then, the upper end of the maintenance switch 5 is connected to the water tank 1 through the pre-drilled hole 6 on the top plate.
[0036] According to the length of the cantilever section of the bridge, the limiting bolt 94 is manually loosened, and the collar 93 is pushed to move horizontally on the guide rod 92. The collar 93 drives one end of the top plate water pipe 2 to move through the retaining ring 95, so that the top plate water pipe 2 drives the flange plate maintenance water pipe 3 to move to the flange plate and bottom plate of the cantilever section of the bridge. The top plate water pipe 2 is then fixed to the hanging basket 8 with tie wire to ensure the stability of the top plate water pipe 2.
[0037] During spray curing, the curing switch 5 is activated via mobile phone or control device. Upon receiving the structural start signal, the water pump is activated, transferring the stored water from water tank 1 to water pipe 2 at the top slab location and water pipe 4 in the inner tank. The stored water in water pipe 2 at the top slab location is transferred through hose 10 to water pipe 3 in the flange plate location, and then sprayed onto the flange plate and bottom slab of the cantilevered bridge section through the curing nozzles 7 on water pipe 3. Simultaneously, the stored water in water pipe 4 in the inner tank is sprayed onto the inner tank web of the cantilevered bridge section through the curing nozzles 7.
[0038] It effectively solves the problem of cracking caused by inadequate curing of high-grade concrete, and features flexible and convenient construction operation, water conservation, and the ability to adjust spraying time according to changes in site weather and temperature, as well as curing effect. It also achieves all-weather, fully moist curing requirements, significantly improving curing quality and effect, solving the problem of inability to cure the web and bottom slab of continuous beams, and improving the quality of concrete products.
[0039] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
