Description

Technical Field

[0001] The utility model belongs to the technical field of building construction and relates to a zero-plate-bottom pipeline anti-settlement structure. Background Technique

[0002] With the development of society, there are more and more housing buildings, and generally drainage projects are also equipped in housing buildings. Joints and drainage pipelines are set in the land under the housing buildings to discharge sewage in the housing buildings.

[0003] In the existing installation method of drainage pipelines in housing building drainage projects, for example, a Chinese patent document discloses a buried pipeline anti-settlement device, a settlement monitoring device and a system [Patent No.: 202221204393.4; Application Publication No.: CN217786156U]. The compensation mechanism and the pipeline are both placed in the soil layer. The compensation mechanism includes a cushion block, a spring and a base. The upper end of the cushion block bears the pipeline. The lower end surface of the cushion block is connected to the base through a spring. A sharp knife is arranged on the lower end surface of the cushion block, and two pulleys are arranged on the upper end surface of the base. The sharp knife is arranged between the two pulleys. One end of the traction belt is connected to the lower end surface of the cushion block, and the other end of the traction belt passes through the two pulleys in sequence and then is connected to the lower end surface of the cushion block; a gap is arranged between the cutting edge of the sharp knife and the two pulleys.

[0004] For the pipeline anti-settlement device with this kind of structure, the drainage pipeline and the housing building are arranged independently. It can maintain a certain stability under hard geological conditions, but in soft geological environments, especially in coastal areas, due to the special soil structure, there are soft soil, silt layers and reclamation land, etc. The settlement speed of the housing building and the foundation often fails to synchronize with that of the drainage pipeline, and there is a problem of uneven settlement, resulting in pipeline damage. For the pipeline anti-settlement device with this kind of structure, the settlement of the pipeline is prevented through a monitoring system and a compensation mechanism. The structure is complex. In ordinary housing buildings, the cost is high and the cost performance is low by using the pipeline anti-settlement device with this kind of structure. Summary of the Invention

[0005] The purpose of the utility model is to propose a zero-plate-bottom pipeline anti-settlement structure for the above problems existing in the prior art, and the technical problem to be solved is how to make the pipeline settle synchronously with the zero plate, make the pipeline not easily damaged, and have a low cost.

[0006] The object of the present utility model can be achieved by the following technical solutions: A zero-plate bottom pipeline anti-settlement structure, a trench is dug below the zero-plate, the pipeline is buried in the trench, and the trench is filled with backfill soil. It is characterized in that the anti-settlement structure includes a left suspension rod, a right suspension rod, a cross bar, a buffer member and a fastener. The tops of the left suspension rod and the right suspension rod are fixedly connected to the zero-plate. The two ends of the cross bar are respectively fixedly connected to the bottoms of the left suspension rod and the right suspension rod. The pipeline passes through the space surrounded by the zero-plate, the left suspension rod, the right suspension rod and the cross bar. The buffer member is fixedly connected to the middle of the cross bar. The fastener is fixedly connected to the cross bar to press the pipeline onto the buffer member.

[0007] The zero-plate is the slab of the first floor of a building. This pipeline is connected to the zero-plate through the left suspension rod, the right suspension rod, the cross bar and the fastener, so that the pipeline and the zero-plate form an integral whole, enabling the pipeline and the zero-plate to settle synchronously, and effectively avoiding the influence of uneven settlement of the backfill soil on the pipeline, making the pipeline not easily damaged. The left suspension rod, the right suspension rod, the cross bar, the buffer member and the fastener are all conventional components with low prices, making the cost of this anti-settlement structure low. The setting of the buffer member plays a buffering role for the pipeline, making the pipeline not easily damaged. The buffer member can be a rubber pad.

[0008] In the above-mentioned zero-plate bottom pipeline anti-settlement structure, the zero-plate is formed by pouring steel bars and concrete. The tops of the left suspension rod and the right suspension rod both extend into the concrete and are fixedly connected to the steel bars by welding. This structure integrates the left suspension rod and the right suspension rod with the steel bars, tightly connecting the pipeline to the building, forming an integral whole, improving the stability of the anti-settlement structure, not only enhancing the supporting ability of the anti-settlement structure for the pipeline, but also helping to reduce the structural deformation caused by external forces or foundation settlement, making the pipeline not easily damaged.

[0009] In the above-mentioned zero-plate bottom pipeline anti-settlement structure, the top of the cross bar is a plane. This structure increases the contact area between the pipeline and the cross bar, making the pressure of the pipeline more evenly distributed on the cross bar, avoiding excessive local stress on the pipeline, and making the pipeline not easily damaged.

[0010] In the above-mentioned zero-plate bottom pipeline anti-settlement structure, the cross-sections of the left suspension rod and the right suspension rod are circular, square or angle-iron shaped.

[0011] In the above-mentioned zero-plate bottom pipeline anti-settlement structure, the fastener is U-shaped, and the U-shaped bottom of the fastener presses on the top of the pipeline. This structure can better fix the pipeline, prevent the pipeline from shifting, and make the pipeline not easily damaged.

[0012] In the above-mentioned anti-settlement structure for pipelines with a zero-plate bottom, the surfaces of the left suspension rod, the right suspension rod, and the cross bar are treated with epoxy coal tar pitch for anti-corrosion. This kind of structure makes the anti-settlement structure not easily damaged, thereby making the pipeline not easily damaged.

[0013] In the above-mentioned anti-settlement structure for pipelines with a zero-plate bottom, both ends of the cross bar are fixedly connected to the bottoms of the left suspension rod and the right suspension rod respectively through fasteners. The fasteners can be a combination of bolts and nuts, which is convenient for fixing connection.

[0014] In the above-mentioned anti-settlement structure for pipelines with a zero-plate bottom, the backfill soil is coarse sand. This makes the backfill soil more uniform, can reduce uneven settlement, and makes the pipeline not easily damaged.

[0015] Compared with the prior art, the anti-settlement structure for pipelines with a zero-plate bottom provided by the present utility model has the following advantages:

[0016] 1. This pipeline is integrated with the zero-plate through the anti-settlement structure, enabling the pipeline and the zero-plate to settle synchronously, and effectively avoiding the influence of uneven settlement of the backfill soil on the pipeline, making the pipeline not easily damaged.

[0017] 2. The left suspension rod, right suspension rod, cross bar, buffer member, and fastening member of this anti-settlement structure are all conventional components, with low prices, making the cost of this anti-settlement structure low. BRIEF DESCRIPTION OF THE DRAWINGS
