Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a steel pipe unit and a steel pipe cable structure. Background Art

[0002] With the development of my country's economy and society, the investment in the construction of small-volume, light-load pipeline projects for transporting oil, natural gas, tap water, etc. is increasing. Such projects are basically infrastructure projects, and their characteristics include long distance, large span, low cost, limited construction equipment and short construction and laying time required on site.

[0003] At present, when pipeline projects such as oil pipelines and water pipes cross obstacles such as ditches, roads, and rivers, steel trusses or piers are usually used to cross the pipelines. For example, the pipelines are set on piers to cross, or pass through the inside of the steel trusses. Due to construction conditions or site restrictions and special topography, large machinery cannot be used, and it is impossible to reduce the span by setting piers. Therefore, many pipeline projects use steel truss structures to achieve pipeline crossing.

[0004] However, common truss structures are large in size and complex to construct. For small-volume, light-loaded water pipes or oil pipes, this type of structure is less economical for pipeline spanning construction.

[0005] Therefore, it is necessary to improve the prior art. Summary of the invention

[0015] According to the above scheme, there are three steel pipe units.

[0016] According to the above scheme, there are two cables shown.

[0027] Preferably, the cable hole 220 is a circular hole.

[0028] In this embodiment, Figure 1 As shown, the cable lug plates 210 are evenly spaced along the outer circumference of the steel pipe section 230 in the axial direction and in the circumferential direction, and four cable lug plates 210 are respectively provided at the upper and lower parts of the steel pipe section 230 .

[0029] like Figures 3-5 A steel pipe cable structure shown is specifically a composite structure of a steel pipe and a cable, comprising a plurality of steel pipe units 200, a pre-buried casing 130, a steel cable 120, a first anchor 100 and a second anchor 150 as described above;

[0030] Each steel pipe unit 200 is assembled end to end in sequence to form a steel pipe structure;

[0031] The first anchor 100 and the second anchor 150 are respectively arranged at two ends of the steel pipe structure;

[0032] The middle part of the embedded sleeve 130 is located in the steel pipe structure and is coaxially arranged with each steel pipe unit 200; both ends of the embedded sleeve 130 extend from the first anchor 100 and the second anchor 150;

[0033] The cable 120 passes through the cable lug plates 210 at corresponding positions on each steel pipe unit 200 in sequence, and both ends of the cable 120 are connected to two anchors respectively.

[0034] In this embodiment, there are three steel pipe units 200.

[0035] In this embodiment, Figure 3 As shown, there are two cables 120. The cables 120 are steel cables.

[0036] In this embodiment, the embedded sleeve 130 needs to pass through all the steel pipe units 200, and the steel cable 120 passes through a plurality of cable lugs 210 symmetrically distributed on both sides of the three steel pipe units 200 to tighten and connect the steel pipe units 200.

[0037] Preferably, a first anchor 110 is fixed on the first anchor 100 , and one end of the cable 120 is connected to the first anchor 110 ; a second anchor 140 is fixed on the second anchor 150 , and the other end of the cable 120 is connected to the second anchor 140 .

[0038] In this embodiment, the steel pipe section 230 can be connected in any number and any standard diameter specification in accordance with national standards and the structural bearing capacity. A plurality of cable lug plates 210 are symmetrically distributed on both sides of the steel pipe section 230, and the cable lug plates 210 can be selected in any standard size specification in accordance with national standards and the structural bearing capacity.

[0039] Example

[0040] In the ecological barrier extension project on the north bank of the Yajiang Bridge, the structure described in this embodiment is used for a 160mm diameter PVC water supply pipe to cross a gully of about 50m in span and 30m in depth. According to the length of the gully and the size of the water supply pipe, appropriate steel pipe sections are selected and placed in sequence at the bottom of the gully to be crossed. After the cable 120 passes through the cable lugs 210 on both sides of the steel pipe section, tension is applied to the cable 120 to raise the steel pipe section 230 at the bottom of the gully to a set height, and then the embedded sleeve 130 is passed through each steel pipe section 230, and then the two ends of the cable 120 are fixed, and then the water supply pipe is passed through the embedded sleeve 130, so that the water supply pipe can cross the gully. In this embodiment, the cable 120 is used to provide vertical stiffness and transmit the vertical load and cable force to the anchors on both sides; the dead weight of the steel pipe section 230 and the embedded sleeve 130 is used as a vertical load to generate partial prestress in the cable 120, causing the cable 120 to deform and not be pulled back under all load conditions. The steel pipe section 230 ensures stability outside the cable plane.

[0041] No large-scale equipment is required during the construction process, and it has the advantages of simple construction and good economy.
