Abstract
The utility model relates to a pipeline stabilizer for a pipeline crossed by rivers, which is composed of annular balancing weight blocks (3) which are arranged on a pipeline (2) at intervals. An adhesive plaster (4) is arranged between the outer wall of the pipeline (2) and the inner wall of each annular balancing weight block (3); the upper part of each annular balancing weight block (3) is provided with a lifting hook (7). Each annular balancing weight block (3) can be composed of two symmetrical semi clamping rings (31), wherein both ends of each semi clamping ring (31) is provided with a groove (9), and a connecting hole is arranged in the groove (9); the two semi clamping rings (31) are fixedly connected by screw bolts (5) and nuts (8). The utility model has the advantage that the proportion can be ensured to reach 1.3 when the filled degree of crossing the plastic pipeline (2) is 90 percents, and also has the advantages of high stability, simple structure, convenient construction and installation, low cost and long service life. The utility model is a pipeline stabilizer for the large-caliber pipeline (2) crossed by long-distance rivers.
Description
Technical field
The utility model relates to a kind of underwater pipeline stabilizing device of River Crossing pipeline, is particularly useful for transmitting the low-pressure liquid, as the underwater pipeline stabilizing device of the large-bore plastics pipeline of water, civil natural gas.
Background technique
At present, the national river crossing pipeline often adopts metallic conduit.But because metallic conduit price height, transportation and difficulty of construction are big, and particularly the heavy caliber metallic conduit is all the more so.And metallic conduit to be embedded in the river underground, be immersed in water for a long time, easily corrosion.In order to solve the etching problem of metallic conduit, people entangle it with metal or cement sleeve pipe, middle filled media, and this is its complex structure not only, and constructional difficulties has more increased cost simultaneously.
The model utility content
The purpose of this utility model provide a kind of simple in structure, with low cost, construction easily, can effectively guarantee the underwater pipeline stabilizing device of pipeline life and quality, reliable and stable River Crossing pipeline.
The purpose of this utility model is achieved in that
A kind of underwater pipeline stabilizing device of River Crossing pipeline, it is made of the annular balancing weight that is disposed on the pipeline.
Be provided with rubber glue between the outer wall of described pipeline and the inwall of annular balancing weight, a suspension hook is arranged at described annular balancing weight top, described annular balancing weight is made of the semi-ring collar of two symmetries, at semi-ring collar two ends groove is set, attachment hole is arranged in the groove, two semi-ring collars are connected and fixed with bolt, nut.
Pipeline of the present utility model adopts plastics such as polyethylene, and its cost is low, in light weight, is convenient to transportation and construction.But intensity is low, and proportion is little, must take the underwater pipeline stabilizing measure; promptly the compartment of terrain is provided with annular balancing weight on pipeline; can make pipeline is 90% o'clock at degree of filling, and proportion reaches 1.3, meets the requirement of the proportion of crossing pipeline; can reach anti-floating effect; also effectively the protective tube pipeline outer wall is avoided the external force mechanical deterioration, at backfilling of pipe canal or when back-silting, can not be out of shape by external force because of topped thing effect causes pipeline; simultaneously suspension hook is set, is convenient to lifting on annular balancing weight top.For the protective tube pipeline outer wall is not scratched, between the inwall of the outer wall of pipeline and annular counterweight ring, be provided with a rubber glue.For ease of installing, annular balancing weight can be made of the semi-ring collar of two symmetries, is provided with groove at semi-ring collar two ends, and attachment hole is arranged in the groove, with screw bolt and nut two semi-ring collars is connected and fixed.
Description of drawings
Accompanying drawing 1 is the local plan view of installing of the present utility model.
Accompanying drawing 2 is side views of annular balancing weight among Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Pipeline 2 is made by plastics such as polyethylene, and diameter can reach more than 0.8 meter.Its cost is low, corrosion resistance and good, long service life.In order to guarantee that pipeline 2 can not be subjected to bigger impact, prevent the damage of external force to its surface, as shown in Figure 1, earlier dig a pipe trench 10 in the river section that will pass through, the degree of depth of pipe trench 10 will reach and make pipeline 2 place stable layer 1 as the rammell, the top of pipeline 2 is greater than 0.8 meter apart from the upper surface of stable layer 1, to guarantee that pipeline 2 is not by scour and impact.Because this pipeline 2 is that 90%～400% o'clock design proportion only is 0.903～1.01 at degree of filling, do not meet the minimum requirement of crossing pipeline design proportion, so the underwater pipeline stabilizing device will be set on pipeline 2, described underwater pipeline stabilizing device is the annular balancing weight 3 that is spaced apart and arranged on the pipeline 2, annular balancing weight 3 is made by cement, wide is 0.6 meter, the span of annular balancing weight 3 on pipeline 2 is 2.4 meters, can guarantee that pipeline is when degree of filling 90%, proportion reaches 1.3, meets the requirement of crossing pipeline design proportion.Being provided with a thickness between the inwall of the outer wall of pipeline 2 and annular balancing weight 3 is the ring rubber glue 4 of 2mm, and for ease of lifting, the top of described annular balancing weight 3 is provided with suspension hook 7.For ease of installing, as shown in Figure 2, annular balancing weight 3 is made up of the semi-ring collar 31 of two symmetries, for guaranteeing join strength, the outer semicircle of semi-ring collar 31 and interior semicircle decentraction, therefore, thicker near the part wall of end, on the two ends of semi-ring collar 31, have groove 9, as having two grooves 8 among Fig. 2, in the groove 8 attachment hole is arranged, bolt 5, packing ring 6, nut 8 with respective numbers are connected and fixed two semi-ring collars 31 by attachment hole.During installation, earlier following semi-ring collar 31 equidistantly is placed on the ground, put into rubber glue 4, again pipeline 2 is put into, and then top semi-ring collar 31 is covered, connect with bolt 5, packing ring 6, nut 8, the underwater pipeline stabilizing device then equidistantly is fixed on the pipeline 2, by suspension hook 7, pipeline 2 and underwater pipeline stabilizing device are hung in the pipe trench 10 then, then pipe trench 10 is carried out backfill.For avoiding river to soak, metalworks such as bolt 5, packing ring 6, nut 8 and suspension ring 7 in the groove 9 are filled with bituminized fabric.
Underwater pipeline stabilizing device of the present utility model also can be used for the River Crossing pipeline made by other materials.
