Technical Problem

然而,该方法存在显著缺陷:首先,由于肥槽空间极其狭窄,机械碾压难以操作,主要依赖人工夯实,导致回填土密实度难以均匀控制,极易引发脚手架的不均匀沉降或倾斜,存在结构开裂风险;其次,该工艺要求必须待肥槽回填完成且土体沉降稳定后方可搭设脚手架,与上部主体结构施工形成严重的工序交叉矛盾,造成工期延长约40%;再者,狭窄空间内同时进行回填作业与脚手架搭设相互干扰,导致材料运输效率降低50%以上;最后,常规落地式脚手架若直接搭设在回填土或地下室顶板上,常因荷载分布不均而对结构造成潜在损伤,往往需要额外采取地基加固措施(如铺设槽钢、浇筑混凝土垫层),进一步增加了施工难度和成本

Benefits of technology

1、本实用新型通过采用波纹管浇筑混凝土形成混凝土基础,并配合工字钢主梁、工字钢次梁构成的架空支撑体系,显著提升了整体结构的稳定性。 波纹管基础直接设置于混凝土垫层上,避免了传统回填土密实度不均导致的沉降风险;工字钢主梁一端锚固于混凝土基础,另一端支撑于稳定的地下室顶板,结合圆钢锚环和木楔的刚性固定,形成了高效传力路径,有效分散了脚手架荷载,极大降低了不均匀沉降或倾覆的安全隐患。

Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a ground-mounted, elevated structure for a trough. Background Technology

[0002] The trench, a narrow space (usually ≤2m wide) between the underground structure's outer wall and the foundation pit support structure, is traditionally constructed by backfilling with lime-soil or plain soil in layers and compacting it as the foundation for the scaffolding. However, this method has significant drawbacks: First, due to the extremely narrow space of the backfill trench, mechanical compaction is difficult to operate, and manual compaction is the main method, making it difficult to control the uniformity of the backfill soil density. This can easily lead to uneven settlement or tilting of the scaffolding, posing a risk of structural cracking. Second, this process requires that the scaffolding can only be erected after the backfill trench is completed and the soil settlement is stable, creating a serious conflict with the construction of the upper main structure and causing the construction period to be extended by about 40%. Third, the simultaneous backfilling and scaffolding erection in the narrow space interfere with each other, resulting in a reduction of material transportation efficiency by more than 50%. Finally, if conventional ground-supported scaffolding is erected directly on the backfill soil or the basement roof, it often causes potential damage to the structure due to uneven load distribution, often requiring additional foundation reinforcement measures (such as laying channel steel and pouring concrete cushion), further increasing the construction difficulty and cost. Utility Model Content

[0003] The purpose of this utility model is to provide a ground-mounted, elevated structure above a fertilizer trough to solve the aforementioned problems in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a ground-supported elevated structure for a fertilizer trough, comprising a concrete foundation, on which multiple corrugated pipes are spaced apart, and concrete is poured into the multiple corrugated pipes to form multiple concrete foundations. The multiple concrete foundations are located on one side of the concrete foundation near the edge, and backfill soil is provided outside the concrete foundations. The side of the backfill soil away from the concrete foundation is the basement roof slab; I-beam main beams are provided above the multiple concrete foundations and the basement roof slab, and two I-beam secondary beams are spaced apart above every two I-beam main beams, with ground-supported scaffolding erected on the I-beam secondary beams.

[0005] In a preferred embodiment, the I-beam main beam is fixedly connected to the concrete foundation by a round steel anchor ring. The round steel anchor ring is U-shaped, with one part of the round steel anchor ring close to the upper horizontal part of the I-beam main beam. The lower ends of the two I-shaped parts of the round steel anchor ring extend into the concrete structure. A pad is filled between one part of the round steel anchor ring and the upper horizontal part of the I-beam main beam. Wooden wedges are wedged on both sides of the web of the I-beam main beam.

[0006] In a preferred embodiment, the spacing between each pair of concrete foundations is 6 meters, the spacing between each pair of I-beam main beams is 6 meters, and the concrete foundations are fixedly connected to the basement roof slab by bolts.

[0007] In a preferred embodiment, the span of the I-beam secondary beam is 6 meters, and the interval between the two I-beam secondary beams is 0.9 meters.

[0008] In a preferred embodiment, the secondary I-beam and the main I-beam are fixedly connected by bolts.

[0009] In a preferred embodiment, the corrugated pipe has a diameter of 400 mm and the concrete strength is C30.

[0010] In a preferred embodiment, the ground-supported scaffolding is erected in two rows on two I-beam secondary beams.

[0011] Compared with the prior art, this utility model has the following features and beneficial effects: 1. This utility model significantly improves the overall structural stability by using corrugated pipes to pour concrete to form a concrete foundation, combined with an overhead support system consisting of I-beam main beams and I-beam secondary beams. The corrugated pipe foundation is directly set on the concrete pad, avoiding the settlement risk caused by uneven compaction of traditional backfill soil; one end of the I-beam main beam is anchored to the concrete foundation, and the other end is supported by the stable basement roof slab. Combined with the rigid fixation of round steel anchor rings and wooden wedges, an efficient force transmission path is formed, effectively dispersing the scaffold load and greatly reducing the safety hazards of uneven settlement or overturning.

[0012] 2. This utility model optimizes the construction process, separating the backfilling of the trench from the erection of the upper scaffolding, significantly shortening the construction period. Traditional methods require waiting for the trench backfilling to be completed and for the scaffolding to stabilize before erection. However, this structure directly constructs an elevated foundation on the original structure, eliminating reliance on the bearing capacity of the backfill soil and allowing scaffolding erection and trench backfilling to proceed simultaneously, thus eliminating the conflict between key processes. Simultaneously, the corrugated pipes also function as formwork, reducing earthwork excavation and formwork procedures, greatly improving material transportation efficiency in confined spaces, and significantly enhancing overall construction efficiency.

[0013] 3. This utility model significantly reduces material waste and overall cost through standardized and reusable component design. Corrugated pipes serve as permanent formwork for concrete foundations, eliminating the costs and waste associated with traditional wooden or steel formwork. The main I-beams, secondary I-beams, and connecting bolts are all removable and reusable materials with a high reuse rate. Attached Figure Description
