Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering, in particular to a concrete pier column maintenance system. Background Art

[0002] Concrete piers are important lower components of bridge structures, and cracks in these piers can directly impact and damage the safety, practicality, durability, and aesthetics of the piers themselves and even the bridge structure. During the concrete pier construction process, cement hydration releases heat. Due to concrete's poor thermal conductivity and its thermal expansion and contraction properties, the internal temperature of the pier rises, causing it to expand, while the external temperature of the pier remains relatively low, causing it to contract. This interaction between the internal and external temperatures can easily lead to significant thermal tensile stresses on the exterior of the pier concrete. When the concrete's tensile strength is insufficient to withstand these stresses, vertical cracking of the pier can occur. By curing the concrete piers with water, the thermal tensile stresses generated by the cement hydration heat can be reduced, preventing cracking of the concrete piers due to excessive external thermal tensile stresses.

[0003] Chinese patent application number CN201820553567.5 discloses an "automatic spraying maintenance device for a pier body". The solution provided by the patent is to set a bracket on the top of the pier column, and set a circle of spray pipes on the bracket. A number of nozzles are set on the spray pipes. By supplying water to each nozzle, each nozzle sprays water mist onto the top of the pier column to realize the watering action of the concrete pier column.

[0004] However, in the solution provided by this patent, each water outlet (sprinkler) has a limited coverage area, and the location of each water outlet must be rationally designed to ensure that the top of the pier is fully covered with water. Therefore, this application proposes a concrete pier maintenance system that can rotate watering to ensure that the top of the concrete pier is fully covered with water. Utility Model Content

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail in combination with the drawings and examples. It should be understood that the described examples are only a part of the examples of the utility model, rather than all the examples. The examples in the utility model and the features in the examples can be combined with each other without conflict. Based on the examples in the utility model, all other examples obtained by the ordinary skilled in the art without creative labor are within the protection scope of the utility model.

[0028] Example one

[0029] Figure 1 An embodiment of the concrete pier maintenance system of the utility model is shown, referring to Figure 1 In the embodiment, the concrete pier maintenance system comprises a water storage pool 1 and a watering mechanism 2.

[0030] Wherein, referring to Figure 1 The watering mechanism 2 comprises a support rod 21 standing on the water storage pool 1 and at least one water spraying unit 22 connected with the top end of the support rod 21. The output end of each water spraying unit 22 is located outside the mouth of the water storage pool 1 and simultaneously faces the clockwise or counterclockwise direction with the axis of the support rod 21 as the center. When the concrete pier needs watering and maintenance after pouring, the water storage pool 1 is arranged at the top of the concrete pier, water is supplied to each water spraying unit 22 respectively, and each water spraying unit 22 sprays water at the same time, the sprayed water pushes each water spraying unit 22 to rotate counterclockwise or clockwise around the axis of the support rod 21 at the same time, so as to rotate and water the top of the concrete pier, avoiding the technical problem that the coverage range is limited when the position of the water spraying unit 22 is fixed. At the same time, the water gravity flow is used to make the outer wall of the concrete pier adhere to water, the heat generated by the evaporation of water is used to absorb heat and dissipate most of the heat generated by the hydration of cement, and the cracking of the concrete pier due to excessive external temperature tensile stress is avoided.

[0031] Specifically, referring to Figure 2The water spraying unit 22 includes a telescopic rod 221 whose fixed end is vertically connected to the top of the support rod 21, a cylinder 222 provided at the movable end of the telescopic rod 221, and at least one nozzle 223 provided on the cylinder 222. By changing the length of each telescopic rod 221, the distance between the water outlet point of each water spraying unit 22 and the axis of the support rod 21 can be changed, thereby changing the coverage range of the rotary watering; at the same time, it can adapt to the watering and maintenance of concrete piers of different coarseness.

[0032] Furthermore, the included angles between the telescopic directions of every two adjacent telescopic rods 221 are consistent, so that the stresses borne by the support rod 21 from all directions in the horizontal plane are balanced.

[0033] Optionally, in this embodiment, providing two telescopic rods 221 is the best embodiment, and the angle between the telescopic directions of the two telescopic rods 221 is 180°.

[0034] Furthermore, the output end of each nozzle 223 is simultaneously directed in a clockwise or counterclockwise direction centered on the axis of the support rod 21, and the output direction of each nozzle 223 is not perpendicular to the telescopic direction of the telescopic rod 221 associated therewith, so that the output water is sprayed toward the top side wall of the concrete pier while rotating watering, avoiding the ejected water not contacting the top side wall of the concrete pier, resulting in less or no water adhesion to the side wall of the concrete pier.

[0035] Furthermore, in the horizontal plane, the output direction of each nozzle 223 of the same water spray unit 22 has an angle of 10° to 80° with the extension direction of the telescopic rod 221; in the vertical plane, the output direction of each nozzle 223 of the same water spray unit 22 has an angle of 10° to 80° with the extension direction of the telescopic rod 221; to ensure that the water extended by each water spray unit 22 is directed toward the top of the concrete pier.

[0036] Optionally, in this embodiment, each water spray unit 22 is provided with a nozzle 223, which is the best embodiment. The angle between the output direction of the nozzle 223 of the same water spray unit 22 in the horizontal plane and the telescopic direction of the telescopic rod 221 is 75°, and the angle between the output direction of the nozzle 223 of the same water spray unit 22 in the vertical plane and the telescopic direction of the telescopic rod 221 is 45°.

[0037] Further, see Figure 2 The movable end of the telescopic rod 221 is provided with a circular hole 224, and one end of the cylinder 222 is movably inserted into the circular hole 224. The movable end of the telescopic rod 221 is provided with a threaded hole 225 connected to the circular hole 224, and a threaded knob 226 is threadedly connected. The threaded knob 226 is screwed so that the threaded knob 226 penetrates into the threaded hole 225 and abuts against the cylinder 222, thereby limiting the cylinder 222 in the circular hole 224, realizing the movable end of the nozzle 223 and the telescopic rod 221.

[0038] Further, see Figure 2 At least one block 227 is provided on the side wall of the cylinder 222 adjacent to one end of the telescopic rod 221, and a matching slot 228 is provided on the inner wall of the circular hole 224 corresponding to each block 227, and each block 227 is respectively inserted into each slot 228 to prevent the cylinder 222 from rotating around its own axis.

[0039] Optionally, in this embodiment, a block 227 is provided on the sidewall of the cylinder 222 adjacent to one end of the telescopic rod 221, and a slot 228 is provided on the inner wall of the circular hole 224, corresponding to the block 227 and matching the block 227. This is the preferred embodiment. This restricts the position of each cylinder 222 relative to its associated telescopic rod 221, preventing changes in the angle between the output direction of the sprinkler head 223 and the length direction of its associated telescopic rod 221, either in the horizontal or vertical plane, during watering.

[0040] Further, see Figure 3 The watering mechanism 2 further includes a first pump body 23 mounted on a support rod 21 and a base 24 mounted within the water reservoir 1. The cylinders 222 are provided with a hollow cavity, which is in communication with each associated nozzle 223. The cavity of each cylinder 222 is connected to the output end of the first pump body 23 via a pipeline, and the input end of the first pump body 23 is in communication with the interior of the water reservoir 1 via a pipeline. The bottom end of the support rod 21 is rotatably connected to the base 24. The first pump body 23 is controlled to perform work to deliver water to the interior of each cylinder 222. When the water pressure within a cylinder 222 exceeds the sum of the minimum pressure thresholds output by all associated nozzles 223, each nozzle 223 ejects a stream of water or a mist of water, while simultaneously generating a force that propels each water spray unit 22 in the opposite direction.

[0041] Optionally, the nozzle 223 is provided with a pressure threshold, and the output pressure of the first pump body 23 is greater than the sum of the pressure thresholds of each nozzle 223. Only when the output pressure of the first pump body 23 is greater than the output pressure of each nozzle 223 can it be ensured that while each nozzle 223 outputs water, the ejected water flow drives each water spray unit 22 to rotate around the axis of the support rod 21.

[0042] In this embodiment, a concrete pier column maintenance system is provided, comprising a water reservoir 1 and a watering mechanism 2. The watering mechanism 2 comprises a support rod 21, a water spraying unit 22, a first pump body 23, and a base 24. By driving the first pump body 23 to work, the water in the water reservoir 1 is transported to each water spraying unit 22. In the horizontal plane, each water spraying unit 22 sprays water in the same direction clockwise or counterclockwise with the support rod 21 as the center. While driving each water spraying unit 22 to rotate around the rotation axis of the support rod 21, it rotates and waters the top of the concrete pier column, thus avoiding the technical problem of limited coverage range when the water spraying unit 22 is fixed. At the same time, water gravity is used to ensure that water adheres to the outer wall of the concrete pier column, and water evaporation absorbs heat to dissipate most of the heat generated by cement hydration, thereby preventing the concrete pier column from cracking due to excessive external temperature tensile stress.

[0043] Example 2

[0044] In order to supply water to the water reservoir 1, based on the above embodiment, see Figure 4 The concrete pier column maintenance system also includes a water supply mechanism 3.

[0045] Among them, see Figure 4 The water supply mechanism 3 includes a second pump body 31 and a check valve 32. The input end of the second pump body 31 is connected to an external water source via a pipeline, while the output end of the second pump body 31 communicates with the interior of the water reservoir 1 via a pipeline. The pipeline connecting the second pump body 31 to the water reservoir 1 is equipped with at least one check valve 32. Controlling the operation of the second pump body 31 delivers external water to the water reservoir 1. Since the water reservoir 1 is located atop a concrete pier, a check valve 32 can be added based on the height of the concrete pier to ensure smooth water delivery to the water reservoir 1.

[0046] Further, see Figure 4 The water supply mechanism 3 is also provided with a liquid level detector 33. The liquid level detector 33 is provided in the water reservoir 1. The water level in the water reservoir 1 is monitored by the liquid level detector 33. When there is less water in the water reservoir 1, the second pump body 31 is controlled to work. When there is more water in the water reservoir 1, the second pump body 31 is controlled to stop working.

[0047] In this embodiment, the concrete pier curing system incorporates a new water supply mechanism 3, comprising a second pump 31 and a check valve 32. This mechanism delivers external water to the water reservoir 1 located at the top of the pier. The output of the second pump 31 is connected to the interior of the water reservoir 1 via a pipeline, and a check valve 32 is provided to prevent backflow. The system is also equipped with a liquid level detector 33, which monitors the water level in the water reservoir 1 and automatically controls the start and stop of the second pump 31 based on the water level to ensure an appropriate water level in the reservoir 1.

[0048] Example 3

[0049] In order to realize intelligent control of the concrete pier column curing system, based on the above embodiment, the concrete pier column curing system further includes a central control mechanism.

[0050] Among them, the central control mechanism is electrically connected to the first pump body 23, the second pump body 31 and the liquid level detector 33 respectively. The central control mechanism pre-stores a number of control instructions. The central control mechanism receives external instructions and signals from the liquid level detector 33, and matches corresponding control instructions to control the first pump body 23 and the second pump body 31 to do work respectively.

[0051] It should be noted that this embodiment focuses on the control principle of the central control mechanism. The specific structure of the central control mechanism is not the focus of this embodiment and is prior art. This embodiment and the accompanying drawings will not elaborate on the specific structure of the central control mechanism. Similarly, this embodiment focuses on the working principle of the first pump body 23, the second pump body 31, and the liquid level detector 33. The specific structure of the first pump body 23, the second pump body 31, and the liquid level detector 33 is not the focus of this embodiment and is prior art. This embodiment and the accompanying drawings have already provided the connection relationship and installation position of the first pump body 23, the second pump body 31, and the liquid level detector 33. The specific structure of the first pump body 23, the second pump body 31, and the liquid level detector 33 will not be elaborated on.
