Description

Technical Field

[0001] This utility model belongs to the field of pipeline installation, specifically a support device for long-distance pipelines crossing landslide sections. Background Technology

[0002] Long-distance pipelines refer to pipelines used to transport media (oil, gas, etc.) between production sites, storage facilities, and user units, spanning provinces and cities, crossing rivers and roads, and containing booster pump stations along the way. In the routine installation environment of long-distance pipelines, there are situations where they need to traverse sections prone to geological disasters such as landslides and mudslides.

[0003] In sections prone to geological disasters, such as landslides, the slope's soil and rock masses, attached to inherent or potential weak structural surfaces, lose their original equilibrium under external forces, resulting in sliding phenomena primarily characterized by horizontal movement. Landslides pose a serious threat to the construction of long-distance pipelines, the safety of pipeline transportation systems, and the operating environment. For the pipeline itself, once a disaster occurs, it can cause the pipeline to become suspended or deformed, or even break completely. Among the three types of pipeline laying (crossing landslides, longitudinally crossing landslides, and diagonally crossing landslides), crossing landslides is the most likely to cause pipeline deformation and damage.

[0004] In road sections prone to geological disasters, due to the time-consuming nature of handling such disasters and the high cost of remediation, the conventional methods for selecting pipeline routes include: bypassing the disaster, tunneling or bridging, and treating the disaster first and then laying the pipeline.

[0005] While bypassing risky sections can be avoided, it also has disadvantages such as increased engineering costs, extended construction period, increased maintenance difficulty, and the occupation of more land resources.

[0006] While tunnel-to-bridge construction can directly and simply avoid the impact of geological disasters, it also has significant drawbacks, including traffic disruption during construction, environmental damage, poor safety, high construction risks, high construction costs, and long construction periods.

[0007] The "treatment before laying" method involves treating geological hazards first, and then laying long-distance pipelines by arranging support columns along the pipeline route in the geological hazard section. This method can greatly reduce the probability of disasters occurring in the geological hazard section and can protect the pipeline from damage to a certain extent. However, it also has disadvantages such as high treatment costs, long treatment cycles, increased technical difficulty and complexity, and the risk of secondary environmental disturbance.

[0010] Furthermore, the transverse connecting bracket includes a transverse connecting beam, and buffer pads are fixed at both ends of the bottom surface of the transverse connecting beam, with a buffer spring fixed at the bottom of each buffer pad.

[0011] The top of the anti-slide pile is provided with an installation groove that is recessed downward along its axis, and the installation groove extends laterally through the inner side of the anti-slide pile; a buffer groove is formed by the bottom of the installation groove being recessed downward; the end of the transverse connecting beam is engaged in the installation groove, and the buffer pad and buffer spring are inserted into the buffer groove.

[0012] Furthermore, the lifting platform includes an insulating sleeve, a lifting platform body, and a support column; both the lifting platform body and the insulating sleeve are arc-shaped, and the insulating sleeve is installed on the inner wall of the lifting platform body; the support column is vertically arranged below the lifting platform body and its top end is fixed to the outer wall of the lifting platform body, and its bottom end is supported by the horizontal connecting bracket.

[0013] Furthermore, the support column includes main support columns located on both sides of the lifting platform body and auxiliary support columns distributed at equal intervals between the two main support columns; vertically, the main support columns are supported directly above the corresponding anti-slide piles by transverse connecting brackets.

By connecting four anti-slide piles to a single support platform to form an integrated anti-slide pile group, compared to individually installed anti-slide piles, the overall integrity is strengthened, the anti-slide performance is improved, and the stability of the long-distance pipeline is enhanced.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0027] In this specification, unless otherwise stated, the terms "vertical," "upper," "lower," "front," "back," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1The orientation or positional relationship shown is for the purpose of describing the present invention only, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0028] Support devices for long-distance pipelines crossing landslide sections, such as... Figure 1 and Figure 2 As shown, the system includes an anti-slide pile assembly and an arc-shaped support platform 2 adapted to support the long-distance pipeline 1. The anti-slide pile assembly comprises four anti-slide piles and a foundation 5. The four anti-slide piles are divided into two groups along the direction of the long-distance pipeline 1, with two anti-slide piles arranged side by side in each group. The four anti-slide piles are connected into a whole by the foundation 5. Each anti-slide pile includes an upper support section 4 located above the foundation 5 and a lower deep-buried section 6 located below the foundation 5 for penetrating the underground bearing layer. A drilling cone 7 is provided at the bottom end of each anti-slide pile. The upper support section 4, the foundation 5, and the lower deep-buried section 6 can be integrally cast by grouting, or the anti-slide piles can be prefabricated and the other parts can be cast by grouting.

[0029] Each group of anti-slide piles is equipped with a transverse connecting bracket 3 and a lifting platform 2. The transverse connecting bracket 3 is installed across the tops of the two anti-slide piles in each group, and the lifting platform 2 is installed on the transverse connecting bracket 3. The direction of the long-distance pipeline 1 is considered longitudinal, and the direction coplanar with and perpendicular to the direction of the long-distance pipeline 1 is considered transverse. The two anti-slide piles in each group are arranged side-by-side along the transverse direction, and the transverse connecting bracket 3 extends along the transverse direction.

[0030] The arc-shaped support platform 2 supports the long-distance pipeline 1 from the bottom, which can provide good support and limit the long-distance pipeline 1, effectively reducing the risk of the long-distance pipeline 1 slipping.

[0031] The support device for this long-distance pipeline crossing the landslide section features anti-slide piles that penetrate deep into the underground bearing layer, reinforcing the strata and preventing landslides, thus achieving the goal of geological hazard mitigation. A transverse connecting support 3 is erected on top of the anti-slide pile group, supporting an arc-shaped support platform 2 for the laying of the long-distance pipeline 1. This allows the anti-slide pile group to not only reinforce the strata and reduce geological hazards but also serve as a supporting structure for the pipeline 1, enabling simultaneous geological hazard mitigation and pipeline laying. This significantly shortens the construction period, reduces time costs, and minimizes the need for manpower and resources. Since only individual anti-slide piles extend underground, the environmental damage is minimal, and land resources are utilized efficiently. This method is suitable for common landslide and debris flow geological hazard scenarios. Alternatively, a support platform 5 can be used to connect four anti-slide piles into a single integrated anti-slide pile group. Compared to individually installed anti-slide piles, this method enhances overall integrity, improves anti-slide performance, and increases the stability of the long-distance pipeline 1.

[0032] The transverse connecting bracket 3 can take various forms, such as a truss. In this embodiment, for example... Figure 4 As shown, the transverse connecting bracket 3 includes a transverse connecting beam 31, and buffer pads 32 are fixed at both ends of the bottom surface of the transverse connecting beam 31, and buffer springs 33 are fixed at the bottom of each buffer pad 32.

[0033] like Figure 5 As shown and Figure 6 As shown, the top of the anti-slide pile is provided with an installation groove 41 that is recessed downwards along its axial direction. The installation groove 41 extends transversely through the inner side of the anti-slide pile. A buffer groove 42 is formed by the bottom of the installation groove 41 being recessed downwards. The end of the transverse connecting beam 31 is engaged in the installation groove 41, and the buffer pad 32 and buffer spring 33 are inserted into the buffer groove 42. During installation, the buffer pad 32 and buffer spring 33 are welded into a whole and then welded to the transverse connecting beam 31. The assembled transverse connecting bracket 3's buffer pad 32 and buffer spring 33 are inserted into the buffer groove 42, and the end of the transverse connecting beam 31 is engaged in the installation groove 41. The empty parts of the installation groove 41 and buffer groove 42 are poured after the installation is confirmed to be correct. The buffer spring 4 has a certain elasticity, which can adjust the angle when the error is large, making the installation of the transverse connecting bracket 3 more convenient.

[0034] In this embodiment, such as Figure 3 As shown, the lifting platform 2 includes an insulating sleeve 21, a lifting platform body 22, and a support column. Both the lifting platform body 22 and the insulating sleeve 21 are arc-shaped. The insulating sleeve 21 is installed on the inner wall of the lifting platform body 22. The support column is vertically arranged below the lifting platform body 22, with its top end fixed to the outer wall of the lifting platform body 22 and its bottom end supported by the transverse connecting bracket 3. The insulating sleeve 21 has a certain elasticity and toughness, which can play a certain buffering role for the long-distance pipeline 1 during installation, thereby protecting the long-distance pipeline 1. The lifting platform body 22 is the main component for supporting the long-distance pipeline 1, and the support column is used to transfer the force on the lifting platform body 22 downward to the transverse connecting bracket 3, which then transfers it to the lower anti-slip pile group.

[0035] To improve the rationality of force distribution, preferably, the support column includes main support columns 23 located on both sides of the lifting platform body 22 and auxiliary support columns 24 evenly distributed between the two main support columns 23; vertically, the main support columns 23 are supported directly above the corresponding anti-slip piles by transverse connecting brackets 3.

[0036] The main support column 23 transmits force directly downwards to the anti-slip pile, while the auxiliary support column 24 provides support along the lateral direction in the middle of the lifting platform 2, offering a support point and mitigating the downward bending deformation in the middle of the lifting platform 2 to some extent. The main support column 23 and the auxiliary support column 24 work together to ensure reasonable force distribution.

[0037] To facilitate the fixing of the main support column 23 to the transverse connecting beam 31, preferably, lower fixing plates 34 are fixed at both ends of the top surface of the transverse connecting beam 31; and an upper fixing plate 25 is fixed at the bottom end of the main support column 23; the lower fixing plates 34 and the upper fixing plates 25 are connected by bolts. Mounting holes for mounting bolts are provided at corresponding positions on both the lower fixing plates 34 and the upper fixing plates 25.

[0038] To facilitate the alignment of the upper fixing plate 25 of the main support 23 with the lower fixing plate 34 of the transverse connecting beam 31, the lower fixing plate 34 and the upper fixing plate 25 are connected by a slot plug.

[0039] The outer wall of the insulating sleeve 21 has protruding protrusions 26, and the inner wall of the lifting platform body 22 has concave grooves 27. The protrusions 26 of the insulating sleeve 21 are engaged with the grooves 27 of the lifting platform body 22. The engagement of the insulating sleeve 21 and the lifting platform body 22 through the protrusions 26 and grooves 27 determines their installation positions, avoids misalignment, and ensures the stability of their installation.

[0040] In the description of this specification, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
