Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering construction technology, and specifically relates to a slope grid beam structure with good integrity and rapid construction. Background Technology

[0002] In the field of water conservancy engineering, slope protection is an important part of ensuring the stability and safety of the project, and slope grid beam support, as a common slope protection method, plays a key role in practical applications.

[0003] Currently, there are two main methods for constructing slope grid beam support: cast-in-place and precast. Cast-in-place slope grid beams, with their excellent integrity, perform exceptionally well in preventing slope slippage and effectively enhance slope stability. However, their complex construction process is a major drawback. From on-site material preparation and formwork erection to concrete pouring and curing, each step requires a significant investment of manpower and material resources, which not only increases construction costs but also extends the construction period.

[0004] Precast slope grid beams exhibit different characteristics. Their process is simple, construction is relatively fast, and they consume relatively less manpower and resources. By prefabricating the grid beam components in the factory and then transporting them to the site for installation, construction time is significantly shortened. However, precast slope grid beams suffer from poor overall integrity. Due to prefabrication, a disconnect can easily occur between the grid beam and the slope, making it difficult for the grid beam to fully exert its supporting function on the slope and posing certain safety hazards. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide a slope grid beam structure with good overall integrity and rapid construction. By adopting a combination of prefabricated grid beams and cast-in-place connection sections, the connection between the grid beams and the slope is enhanced while ensuring construction efficiency, thereby improving the overall performance of the slope grid beam support and providing a more reliable guarantee for slope protection in water conservancy projects.

[0006] The technical solution of this utility model is as follows: a slope grid beam structure with good integrity and quick construction, including a precast grid beam, a cast-in-place connecting section, exposed steel bar sections, a cover mold and a concrete pouring port. The precast grid beam has exposed steel bar sections on both sides. The cast-in-place connecting section is located between two adjacent precast grid beams. The cast-in-place connecting section is provided with a cover mold, and the cover mold is provided with a concrete pouring port.

[0007] The precast grid beam is a precast reinforced concrete structure, and the cast-in-place connection section is a cast-in-place concrete structure.

[0008] The length of the exposed steel bar section extending beyond the precast grid beam shall not be less than the anchorage length of the exposed steel bar.

[0009] The cover mold is fixedly connected to the precast grid beams on both sides of the cast-in-place connection section.

[0010] The cover mold and the precast grid beams on both sides of the cast-in-place connection section are fixedly connected by bolts.

[0011] The size of the concrete pouring opening meets the requirements for concrete pouring and vibration.

[0012] The technical advantages of this utility model are as follows: 1. By adopting a combination of prefabricated grid beams and cast-in-place connection sections, this utility model enhances the connection between the grid beams and the slope while ensuring construction efficiency, thereby improving the overall performance of the grid beam support for the slope and providing a more reliable guarantee for slope protection in water conservancy projects. 2. This utility model combines prefabrication and cast-in-place construction. During construction, some components are prefabricated first, taking advantage of factory production. The process is simple and can quickly complete the production of a large number of components, reducing on-site construction time and manpower and material consumption. Subsequently, the components are cast-in-place to ensure a tight connection between the parts, enhancing the stability and firmness of the overall structure, ensuring good integrity, and allowing the grid beams to be tightly connected to the slope, thus improving the slope protection effect and providing a new solution for slope protection in water conservancy projects.

[0013] The following will provide further explanation in conjunction with the accompanying drawings. Attached Figure Description
