Description

Technical Field

[0001] This utility model relates to the field of hydropower engineering construction technology, specifically to a fog cannon installation platform based on the dam slope. Background Technology

[0002] Roller-compacted concrete dams are constructed using a layered unloading, spreading, and compaction method. During construction, the surface of the roller-compacted concrete should be kept moist. Especially when constructing in windy, dry, or high-temperature climates, surface spraying measures are required to create a microclimate on the concrete surface to prevent moisture loss and ensure the construction quality of the interlayer bonding of the roller-compacted concrete.

[0003] The upstream bottom of a roller-compacted concrete dam is typically a small slope with a slope ratio of 1:0.2, while the downstream section is entirely sloped with a slope ratio between 1:0.7 and 1:0.8.

[0004] Because the top area of ​​the dam is relatively small, it is difficult to place mobile sprayers, spray trucks and other equipment directly on the dam surface for spraying operations, which would greatly interfere with the construction space on the surface and have adverse effects.

[0005] To solve this problem, it is necessary to develop a platform that does not occupy the working environment at the top of the dam and can provide an installation environment for the fog cannon, so as to ensure the moisture of the roller-compacted concrete dam surface. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by providing a fog cannon installation platform based on the dam slope that utilizes inclined steel formwork as support and does not occupy the working space on the dam surface.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a fog cannon installation platform based on a dam slope, including a sloping steel template, an installation platform, and platform support legs;

[0008] The inclined steel formwork is a steel formwork used to form the inclined surface of a roller-compacted concrete dam. In the supported state, the highest point of the formwork support of the inclined steel formwork is provided with a support part, and the point of the formwork support of the inclined steel formwork closest to the surface of the roller-compacted concrete dam is provided with two hinged parts.

[0009] The platform has two legs located on the same side of the mounting platform, and the bottom ends of the two platform legs are hinged to the hinge joint.

[0010] The main body of the installation platform can rotate around the hinge. When the installation platform rotates to a horizontal position, the lower end face of the main body of the installation platform is supported by the support.

[0011] Preferably, the formwork support of the inclined steel formwork is in the form of a truss.

[0012] Preferably, the support portion of the template bracket is provided with a thickened steel beam.

[0013] Preferably, the support plate is installed on the support side of the template support.

[0014] Preferably, the platform legs are flat steel with holes at the bottom. The bottom of the flat steel is aligned with the hole of the hinge part and is hinged by bolts, nuts and washers.

[0015] Preferably, the installation platform is an enclosed platform with a fence, and the platform legs extend downward from two corners on the same side of the installation platform, perpendicular to the platform surface.

[0016] Preferably, the horizontal distance between the support and the hinge is greater than half the span of the installation platform.

[0017] Preferably, the guardrail of the installation platform is formed by welding several steel pipes together.

[0018] Preferably, the platform surface of the installation platform is a patterned steel plate.

[0019] Preferably, the slope ratio of the roller-compacted concrete dam is between 1:0.2 and 1:0.8.

[0020] This utility model has substantial features and progress compared with the prior art. Specifically, this utility model uses the sloping formwork of the roller-compacted concrete dam as the foundation, takes its highest point in the supported state as the support part, and the point closest to the surface of the roller-compacted concrete dam as the hinge part. Then, an installation platform is set on this basis. The two legs of the installation platform are hinged to the hinge part, and the installation platform itself is supported on the support part. In the supported state, the installation platform is in a horizontal state, forming a platform for installing the fog cannon.

[0021] This method effectively avoids the fog cannon occupying limited warehouse platform area resources, avoids interfering with normal warehouse operations, and at the same time ensures the spraying needs of the platform surface. Attached Figure Description

[0026] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0027] like Figures 1-3 As shown, a fog cannon installation platform based on a dam slope includes a sloping steel formwork 1, an installation platform 2, and platform legs 3.

[0028] The inclined steel formwork 1 is a steel formwork used for forming the inclined surface of the roller-compacted concrete dam 4. The formwork support of the inclined steel formwork 1 is in the form of a truss, and the support plate is installed on the support side of the formwork support.

[0029] The upstream bottom of a roller-compacted concrete dam is generally a small slope with a slope ratio of 1:0.2, while the downstream is entirely sloped with a slope ratio between 1:0.7 and 1:0.8. Therefore, the inclined steel formwork is also inclined under the support condition. Under the support condition, the highest point of the formwork support of the inclined steel formwork is provided with a support part 5, and two hinge parts 6 are provided at the point of the formwork support closest to the surface of the roller-compacted concrete dam. Two horizontal hinge holes are machined at the hinge parts 6.

[0030] The installation platform 2 is an enclosed platform with a fence. The fence is formed by welding several steel pipes together. The platform surface of the installation platform 2 is made of Q235B patterned plate with a thickness of 4mm, which serves as the installation working surface for the fog cannon.

[0031] The platform support leg 3 is provided in two parts and is located on the same side of the mounting platform 2. The platform support leg 3 extends downward from the two corners on the same side of the mounting platform 2, and the connection is fixed by welding. It is perpendicular to the platform surface of the mounting platform, and the bottom ends of the two platform support legs 3 are hinged to the hinge part 6.

[0032] Specifically, the platform support leg 3 is made of flat steel, with a hole at the bottom end. The bottom end of the flat steel is aligned with the hole of the hinge part, and the hinge connection is achieved through bolts 7, nuts 8 and washers 9.

[0033] The main body of the installation platform 2 can rotate around the hinge 6. When the installation platform 2 rotates to a horizontal position, the lower end face of the main body of the installation platform 2 is supported by the support part 5. In a preferred embodiment, to ensure support strength, the support part of the template bracket is provided with a thickened steel beam.

[0034] Since the installation platform 2 is a movable platform, the horizontal distance between the support part 5 and the hinge part 6 is greater than half the span of the installation platform 2, thus maintaining stability in the supported state.

[0035] Example:

[0036] The scheme was validated 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.

[0037] The upstream bottom section of this project is a slope with a slope ratio of 1:0.2, and the downstream slope ratio is 1:0.78. Both are constructed using inclined formwork.

[0038] During actual construction, the number of fog cannons to be installed is determined based on the size of the pouring area and the coverage area of ​​the fog cannons, and a corresponding number of installation platforms are prefabricated.

[0039] After all the inclined steel formwork is completed, install each platform and mist cannon one by one, and confirm that the wiring is safe and complete. Start the mist cannon to begin the surface construction. After the surface construction is completed, lift the mist cannon off the platform to prepare for the next layer of roller-compacted concrete construction, and so on.

[0040] 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.
