Description
Technical Field
[0001] The utility model belongs to the technical field of anti-settling, and relates to a coastal pipeline anti-settling structure. Background Art
[0002] When constructing buildings in coastal areas, the rainwater pipes and sewage pipes in the buildings are connected to the outside. A common practice is to connect them to the rainwater and sewage wells through pipes directly buried outside through the exterior wall, and the pipes are generally rigid cement pipes. In fact, since the settlement rate and settlement amount of the strata around the building are much greater than the settlement rate and settlement amount of the building itself, this leads to problems such as pipe breaking and joint detachment. The pipes are damaged and cause water leakage. The leakage further leads to soil loss around the pipes, hollowing out the surrounding strata, aggravating the uneven settlement of the surface around the building, and posing certain safety hazards to the building. Drinking water supply pipes and fire water supply pipes also have similar problems of breaking and joint detachment. Summary of the invention
[0003] The purpose of the utility model is to solve the above problems existing in the prior art and propose a coastal pipeline anti-settling structure, which solves the technical problem of how to make the pipelines in coastal areas less prone to damage.
[0004] The purpose of the utility model can be achieved through the following technical solutions: a coastal pipeline anti-subsidence structure, the pipeline includes a rigid pipeline for connecting indoors and outdoors and an inspection well located outdoors, characterized in that the anti-subsidence structure includes a retractable and bendable flexible pipeline located outdoors, a first end plate and a second end plate fixedly connected to both ends of the flexible pipeline, and a third end plate fixedly connected to the outer end of the rigid pipeline, the first end plate is fixedly connected to the wall of the inspection well by a first fastener, and the second end plate and the third end plate are fixedly connected by a second fastener.
[0005] The flexible pipe located outdoors is bendable, twistable, stretchable and compressible, and can withstand external forces up to 5MPa, making the flexible pipe highly applicable. When the outdoor area sinks, the position and shape of the flexible pipe will be adaptively adjusted according to the sinking area to avoid the problem of rupture of the flexible pipe, so that the pipelines in coastal areas are not easily damaged, effectively preventing pipeline leakage and ensuring the safety of the building. The first end plate is set so that one end of the flexible pipe is connected to the inspection well, so that one end of the flexible pipe can sink with the inspection well, making the pipelines in coastal areas not easily damaged. The second end plate and the third end plate are set to improve the strength of the connection between the rigid pipe and the flexible pipe, so that the rigid pipe and the flexible pipe are not easily broken at this location, making the pipelines in coastal areas not easily damaged. The anti-settlement structure takes active settlement measures at the junction of the entrance and exit, so that the pipelines in coastal areas are not easily damaged.
[0006] In the above-mentioned coastal pipeline anti-settling structure, the first end plate is located in the inspection well, and the first end plate is located at the upper part of the inspection well. This structure facilitates the installation and maintenance of the first end plate and makes the fluid in the pipeline flow smoothly.
[0007] In the above-mentioned coastal pipeline anti-settling structure, a rubber gasket is provided between the second end plate and the third end plate for sealing. This structure ensures the sealing between the rigid pipeline and the flexible pipeline, so that leakage will not occur there.
[0008] In the above-mentioned anti-settling structure for coastal pipelines, a plurality of first fixing holes are arranged at intervals on the circumferential edge of the first end plate, the first fastener is a bolt, the aperture of the first fixing hole is larger than the outer diameter of the bolt rod, and the aperture of the first fixing hole is smaller than the outer diameter of the bolt head, and the first fastener passes through the first fixing hole and is penetrated in the wall of the inspection well, so that the first end plate is fixedly connected to the wall of the inspection well. This structure is a universal connection. Although the first fastener locks the first end plate, the first fastener and the first end plate can have a certain amount of relative movement under the action of external force, so that the flexible pipeline can have a certain deflection and displacement relative to the inspection well, so that the flexible pipeline can better adapt to the settlement of the inspection well and the settlement of the outdoor area, so that the connection is not prone to squeeze dislocation leakage, tensile cracking leakage, etc., and the problem of flexible pipeline rupture is avoided, so that the pipeline in the coastal area is not easy to be damaged, and the safety of the building is guaranteed.
[0009] As another case, in the above-mentioned anti-sinking structure of a coastal pipeline, a plurality of first fixing holes are arranged at intervals on the circumferential edge of the first end plate, a fourth end plate is fixedly connected to the wall of the inspection well, a plurality of fourth fixing holes are arranged at intervals on the circumferential edge of the fourth end plate, the first fastener is a bolt, the aperture of the first fixing hole is larger than the outer diameter of the bolt rod, and the aperture of the first fixing hole is smaller than the outer diameter of the bolt head, and the first fastener passes through the first fixing hole and is inserted into the fourth fixing hole for locking, so that the first end plate is fixedly connected to the wall of the inspection well. This structure is a universal connection. Although the first fastener locks the first end plate, the first fastener and the first end plate can have a certain amount of relative movement under the action of external force, so that the flexible pipeline can have a certain deflection and displacement relative to the inspection well, so that the flexible pipeline can better adapt to the settlement of the inspection well and the settlement of the outdoor area, so that the connection is not prone to squeeze dislocation leakage, tensile cracking leakage, etc., and the problem of flexible pipeline rupture is avoided, so that the pipeline in the coastal area is not easy to be damaged, and the safety of the building is ensured.
[0010] In the above-mentioned coastal pipeline anti-subsidence structure, a plurality of second fixing holes are arranged at intervals on the circumferential edge of the second end plate, a plurality of third fixing holes are arranged at intervals on the circumferential edge of the third end plate, the second fastener is a combination of a bolt and a nut, the aperture of the second fixing hole and / or the aperture of the third fixing hole is larger than the outer diameter of the bolt rod, the aperture of the second fixing hole and the aperture of the third fixing hole are both smaller than the outer diameter of the bolt head and the outer diameter of the nut, the second fastener passes through the second fixing hole and the third fixing hole and is locked, so that the second end plate and the third end plate are fixedly connected. This structure is a universal connection. Although the second fastener locks the second end plate and the third end plate, the second fastener, the second end plate and the third end plate can move relative to each other to a certain extent under the action of external force, so that the flexible pipe can have a certain deflection and offset relative to the rigid pipe, so that the flexible pipe can better adapt to the settlement of the outdoor area, and the connection is not prone to extrusion dislocation leakage, stretching cracking leakage, etc., avoiding the problem of rupture of the flexible pipe, thereby making the pipeline in the coastal area not easy to be damaged, ensuring the safety of the building.
[0011] In the above-mentioned coastal pipeline anti-settling structure, the flexible pipe is a plastic corrugated pipe or a metal corrugated pipe.
[0012] In the above-mentioned coastal pipeline anti-subsidence structure, the rigid pipeline is a cement pipe, a plastic pipe or a metal pipe.
[0013] Compared with the prior art, the coastal pipeline anti-settling structure provided by the utility model has the following advantages:
[0014] 1. The position and shape of the flexible pipe of this anti-subsidence structure will be adaptively adjusted according to the subsidence area to avoid the problem of rupture of the flexible pipe, so that the pipeline in the coastal area is not easily damaged, effectively preventing leakage of the pipeline and ensuring the safety of the building.
[0015] 2. Both ends of the flexible pipe of the anti-settling structure are designed with universal connections, so that both ends of the flexible pipe can undergo a certain degree of deflection and offset, making it less likely for the connection to have squeezed dislocation leakage, tensile cracking leakage, etc., avoiding the problem of flexible pipe rupture, thereby making the pipelines in coastal areas less likely to be damaged and ensuring the safety of buildings.
