Description

Technical Field

[0001] This utility model relates to the field of concrete pier spray curing technology, and more specifically to the field of concrete pier spray curing system technology. Background Technology

[0002] Concrete piers are common vertical load-bearing components in civil engineering, primarily used in bridges, viaducts, and building structures to bear the load from the superstructure and transfer it to the foundation. They are upright column-shaped structures made of reinforced concrete or plain concrete, with cross-sections typically circular, rectangular, or polygonal. They bear vertical forces (such as the weight of vehicles, equipment, and buildings) transmitted from the superstructure beams and slabs, and resist horizontal forces such as wind loads and seismic forces. In bridges, they connect the pile foundations and the cap beams, forming a force transmission path.

[0003] A concrete pier spray curing system is an automated curing device used to maintain appropriate humidity and control temperature of concrete piers after pouring, thereby ensuring their strength development and durability. Existing patents disclose the following technologies:

[0004] Patent publication number CN119686220A, entitled "Intelligent Spray Curing Device and Operation Method for High Pier Column Concrete," discloses the following: An intelligent spray curing device and operation method for high pier column concrete includes a top ring water pipe at the top of the column, a bottom ring water pipe at the bottom of the column, and multiple vertical water pipes arranged in a circular pattern around the outside of the column, with the vertical water pipes, top ring water pipe, and bottom ring water pipe interconnected; simultaneously, multiple nozzles A are installed on the lower side of the top ring water pipe, and multiple humidity meters are installed from top to bottom on each vertical water pipe. Each vertical water pipe has multiple nozzles B installed at the top of the column, and multiple nozzles C are installed in a spiral pattern from bottom to top on multiple vertical water pipes. Furthermore, a sealing cover is provided outside the column, which together encloses the column, the top ring water pipe, the multiple vertical water pipes, and the bottom ring water pipe from top to bottom. The bottom of the sealing cover is covered with gravel to form a closed and permeable mist of water droplets. Therefore, this invention has the advantages of simple structure, safety and economy, convenient construction, energy saving and emission reduction, and high economic benefits.

[0005] The patent with announcement number CN212895941U, entitled "An Intelligent Spray Curing Device for Slipform Concrete of High Bridge Piers," discloses the following: An intelligent spray curing device for slipform concrete of high bridge piers includes a support platform arranged around the pier and at a certain distance from it. The support platform is connected to the slipform template at the top of the pier via slings. A water pipe is provided on the side of the support platform near the pier, and multiple nozzles are provided on the water pipe. Multiple support guide wheel mechanisms are also provided on the side of the support platform near the pier, abutting against the surface of the pier. A windproof guardrail is provided on the side of the support platform away from the pier. A water tank is provided on the ground near the pier, and a water pump connected to the water pipe is provided in the water tank. A power distribution cabinet and a time controller are also provided, with the power distribution cabinet electrically connected to the water pump via the time controller. It also includes a water collection trough arranged around the lower part of the pier and close to the pier, with the outlet of the water collection trough aligned with the top of the water tank. This invention can provide comprehensive spraying maintenance for pier columns, ensuring even water distribution, preventing interference from crosswinds, saving manpower, reducing operational risks, and allowing the maintenance water to be recycled.

[0006] Although the concrete spray curing device disclosed in the above patent can perform the function of spray pipe curing, it has the disadvantages of complex structure and uneven spraying. Utility Model Content

[0007] The purpose of this utility model is to provide a concrete pier column spray curing system in order to solve the above-mentioned technical problems.

[0008] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0009] This utility model provides a concrete pier spray curing system, including a water tank installed on the top of a rectangular concrete pier, a spray pipe system set at the bottom of the water tank, a spray piston set inside the water tank, a piston force transmission device connected to the top of the spray piston, and an external force application device for applying external force to the piston force transmission device.

[0010] In one embodiment, the external force application device includes two support column assemblies symmetrically arranged at the left and right ends of the water tank, a counterweight force transmission guide beam fixedly connected to the top of the piston force transmission device, two spray pressure counterweights arranged at both ends of the counterweight force transmission guide beam and driven to rise and fall by the counterweight connecting steel ropes, and two counterweight balance steel ropes.

[0011] The two ends of the counterweight force transmission guide beam are in contact with the two support column components through a sliding manner, and each spray pressure counterweight is connected to one end of the counterweight force transmission guide beam through at least two counterweight connecting steel ropes.

[0012] Each support column assembly is equipped with a fixed pulley at the top. One end of each counterweight balance steel rope is connected to the corresponding spray pressure counterweight, and the other end is anchored to the support platform at the bottom of the rectangular concrete pier after passing over the corresponding fixed pulley.

[0013] Specifically, the water reservoir is fixed to the top of the completed rectangular concrete pier. A spray piston is installed inside the water reservoir, and the spray piston is connected and fixed to the counterweight transmission guide beam through a piston force transmission device. Connecting hinges are installed at both ends of the counterweight transmission guide beam to suspend the spray pressure counterweight.

[0014] In one embodiment, the counterweight balance steel rope is connected to a ground anchor installed on the receiving platform, and a pulley is installed on the ground anchor to realize the winding and unwinding of the counterweight balance steel rope.

[0015] Specifically, when maintenance is required, the counterweight balance steel rope is loosened, and the two ends of the spray pressure counterweight transmit the gravity to the spray pressure transmitter through the counterweight force transmission guide beam, thereby pushing the spray piston to move downward, and the spray pipeline system starts to work.

[0023] The spray piston forces water from the reservoir through the spray valve, which then distributes the water through a distributor, plastic hose, and curing spray heads onto the cast-in-place piers, thus achieving curing. During curing, the angle of the curing spray heads can be adjusted to achieve full coverage of the cast-in-place rectangular concrete piers.

[0024] In one embodiment, the water distribution device includes a horizontally arranged collecting pipe that is connected to the main water outlet pipe in the middle. Two hose connection devices are provided at the left and right ends of the collecting pipe.
