Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction equipment technology, specifically, to a convenient, mobile, multi-interface small water tank for dam construction. Background Technology

[0002] As the dam is poured with concrete, it will gradually rise. During the construction process, a large amount of water is often needed for tasks such as washing the dam surface, curing the concrete, spraying moisture, and washing the tires of construction vehicles.

[0003] Current water supply technology for dam construction often involves setting up elevated water tanks at reasonable locations on both sides of the dam, and then drawing water supply pipes from the tanks to the dam surface for use. However, when the dam pouring area is large and multiple water sources are required, this technology suffers from problems such as the need to draw multiple pipes, chaotic pipe distribution, and disruption to surface construction. Therefore, how to set up a convenient, mobile, multi-interface water supply system to meet the water needs of the dam surface is an urgent problem for technical personnel to solve.

[0004] Currently, there is a lack of systematic management measures for the output water supply pipelines. In order to achieve the management of water supply pipelines, it is necessary to rely on some relay water facilities, and these relay water facilities are new equipment that urgently need to be developed. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a convenient, mobile, multi-interface small water tank for dam construction that can be used as a relay water supply device, reduces the number of water supply pipelines between the tank and the water source, and facilitates the management of surface water supply pipelines.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a convenient mobile multi-interface small water tank for dam construction, including a water tank, branch pipes and steel support frame;

[0007] The water tank is provided with an inlet on its side for connecting to an external water supply pipeline to a water source;

[0008] The main body of the water tank is cylindrical, and several branch pipes are distributed along the length of the main body of the water tank for connecting to the downstream water outlet pipe.

[0009] The steel support frame is used to support the water tank.

[0010] Preferably, the water tank includes a main body, an end steel plate, and an end steel plate. The end steel plate is welded to one end of the main body and has the water inlet provided thereon. The end steel plate is welded to the other end of the main body.

[0011] Preferably, the main body is a cut steel pipe.

[0012] Preferably, both the end steel plate and the end steel plate are rectangular.

[0013] Preferably, the end steel plate is rectangular and the end steel plate is circular.

[0014] Preferably, several of the branch pipes are distributed in a V-shape on the side of the main body of the water tank.

[0015] Preferably, each branch pipe is equipped with an on / off valve.

[0016] Preferably, the water tank is welded and fixed to the steel support frame.

[0017] Preferably, the material of the steel bar support frame is 14mm threaded steel.

[0018] Preferably, the steel pipe is a DN200 steel pipe, and the end plates and tail plates are both 5mm thick Q235B steel plates.

[0019] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model designs a small water tank with multiple interfaces. The water inlet is connected to the water supply tank outside the dam through a water supply pipe, which greatly reduces the number of pipes directly connected to the water supply tank outside the dam. Each branch pipe is connected to the subsequent water supply pipe, which delivers the water flow to the required position on the dam surface, playing a relay role. This controls the overall number of water supply pipes and facilitates the management of the water supply pipes on the surface.

[0020] Furthermore, by designing the steel plates on both ends of the water tank as rectangles, the water tank can be placed stably without the need for supports or additional fixing equipment, making it more user-friendly.

[0021] Each branch pipe is equipped with an on / off valve, which can manage the opening and closing control of the downstream water supply pipeline, providing high flexibility. Attached Figure Description

[0025] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0026] like Figure 1 and Figure 2 As shown, a convenient mobile multi-interface small water tank for dam construction includes a water tank 4, a branch pipe 5, and a steel support frame 7.

[0027] The water tank 4 is provided with a water inlet on its side for connecting to the water supply pipe 2 and the water source 1.

[0028] Specifically, in this embodiment, the main body of the water tank 4 is cylindrical, cut from a DN200mm steel pipe, and is 60cm long. The main body of the water tank 4 has several branch pipes 5 distributed along its length for connecting to the downstream water outlet pipe. Opening and closing valves are installed on the branch pipes 5.

[0029] In this embodiment, the branch pipe 5 is formed by welding the first section of DN20mm steel pipe 51, the on / off valve 52, and the second section of DN20mm steel pipe 53. The second section of DN20mm steel pipe 53 is welded and fixed to the outside of the main body and communicates with the inside of the water tank 4.

[0030] In terms of quantity, a total of 6 branch pipes 5 are set. During manufacturing, 20mm holes are first reserved on the side of the water tank 4, with a hole spacing of 150mm, in two rows. The single row is arranged along the axial direction. After the branch pipes 5 are installed, the whole structure presents a V-shaped distribution.

[0031] The steel reinforcement support frame 7 is used to support the water tank 4. The steel reinforcement support frame is made of 14mm threaded steel and has longitudinal tie rods 8 for connecting the two end uprights of the support in the axial direction. The crossbar 9 serves as the top support steel bar of the steel reinforcement support frame, and the horizontal tie rod 10 serves as the transverse connecting steel bar of the steel reinforcement support frame.

[0032] The water tank 4 also includes an end steel plate 3 and an end steel plate 6. Both the end steel plate 3 and the end steel plate 6 are 5mm thick Q235B steel plates. The end steel plate 3 is welded to one end of the main body and is provided with the water inlet. The end steel plate 6 is welded to the other end of the main body for sealing the water tank.

[0033] In this embodiment, both the end steel plate 3 and the end steel plate 6 are rectangular. In this case, the water tank 4 itself has self-stabilizing capabilities and can be placed anywhere on the required platform. In another embodiment, the end steel plate is rectangular and the end steel plate is circular, so that the pipe side can be easily processed, and the water tank is mainly supported by the steel reinforcement support frame at the bottom.

[0034] Specific application examples:

[0035] This plan is based on relevant experiments conducted during the concrete construction of the dam in the civil engineering and metal structure installation project of the upper reservoir of the Yunxiao Pumped Storage Power Station in Fujian.

[0036] Specific implementation method: The roller-compacted concrete dam of this project is 1305m long, 68.2m high, and 55-8m wide. Utilizing the existing terrain, a high-level water supply tank will be set up at intervals of 400-500m outside the dam to supply the water needed for dam construction. Water will be transported to the dam surface through a DN40mm HDEPE water supply pipeline by a pressurized pump and finally connected to a multi-port small water tank inside the dam. The length of the pipeline will be gradually adjusted as the dam is poured and raised.

[0037] As needed, multiple multi-port small water tanks are fabricated on-site to facilitate construction water use such as surface flushing and misting. Each multi-port small water tank is welded from a 60cm long DN200mm steel pipe and end plates. The steel plates are all made of 5mm thick Q235B steel. The end plate is square, with a size of 260*260mm, and a DN40mm hole is reserved in the middle for the connection of the water supply pipeline to the external water tank. The end plate is round, with a size of DN200mm, and is used to seal the water tank.

[0038] The DN200mm steel pipe water tank has DN20mm holes pre-drilled on both sides at 150mm intervals for the installation of branch pipes, with a total of 6 branch pipes. Each branch pipe consists of two DN20mm steel pipes and an on / off valve, which controls the water supply to the branch pipe. When water is needed on site, it can be supplied for construction by connecting a flexible hose and opening the on / off valve.

[0039] The steel reinforcement support frame mainly serves as an installation platform for the multi-port small water tank inside the dam. It consists of four 20cm long steel reinforcement support frame uprights, two 55cm long steel reinforcement support frame longitudinal tie rods, two 30cm long steel reinforcement support frame crossbars, and two 20cm long steel reinforcement support frame horizontal tie rods, all welded together. The steel reinforcements are all 14mm diameter threaded steel bars, and are ultimately welded to the multi-port small water tank inside the dam to form a fixed support for the multi-port small water tank during daily use.

[0040] By installing a convenient, mobile, multi-interface small water tank inside the dam reservoir, the water needs of different construction sites in multiple parts of the dam can be met. The device is easy to move and simple to manufacture, avoiding the problems of uneconomical supply costs and chaotic pipeline layout caused by multiple pipelines introduced into the dam in existing water supply technologies.

[0041] Finally, it should be noted that: the preferred embodiments of this patent have been described in detail above, but this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
