Description

Technical Field

[0001] The utility model relates to the technical field of pipeline anti-floating, in particular to a multi-layer pipe anti-floating lock in high water level areas. Background Art

[0002] With the rapid development of municipal roads, various underground pipelines are becoming increasingly complex, making their construction extremely important. Improving the construction technology of underground pipelines and preventing them from being damaged will, to a large extent, directly determine whether the surrounding residents can live normally.

[0003] In recent years, underground pipeline construction technology has gained increasing attention. Traditional pipeline construction in high-water areas often results in seepage water eroding the pipelines due to high groundwater levels, pushing them out of their original positions and causing dislocation and damage. Furthermore, leakage is a serious problem in high-water areas, posing a significant safety hazard to power pipeline construction. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-layer anti-floating lock for pipes in high water level areas to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A multi-layer anti-floating lock for drainage pipes in high-water areas comprises an external locking sleeve, an internal pipeline fixing portion, and an internal connecting device; the internal pipeline fixing portion is a plurality of steel sheets with pipe penetration holes, the pipe penetration holes being used for passing pipelines, the steel sheets being arranged in a rectangular shape and adjacent steel sheets being connected by an internal connecting device, the internal pipeline fixing portion being connected to the external locking sleeve by the internal connecting device; holes are left on both sides and the bottom of the external locking sleeve for connecting to an anchoring device.

[0007] As a further solution of the present invention: the internal connecting device is a thick spring with hooks at both ends.

[0008] As a further solution of the present invention: the end of the anchoring device is composed of an anchor head, a spring, and a gasket. The anchor head is arrow-shaped and hollow inside. The gasket is welded inside the anchor head. The spring is welded to the other end of the gasket, and the bottom end of the spring is welded to the anchor head.

[0009] Compared with the existing technology, the beneficial effects of the utility model are: it can save construction time and cost; at the same time, it can reduce the dislocation and damage of pipelines caused by seepage water scouring the pipelines when the groundwater level is too high during backfilling with bare soil; when concrete pouring is used for encapsulation, it can prevent the pipelines from floating up due to concrete pouring.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0019] See also Figure 1-7 This utility model provides a multi-layer anti-floating lock for high-water areas. Its structure includes an external locking sleeve 9, an internal pipeline fixing portion, and an internal connecting device 7. The internal pipeline fixing portion comprises a plurality of steel plates 6 with pipe holes 10 for inserting pipelines. The steel plates 6 are connected by the internal connecting device 7.

[0020] Preferably, considering that the components will be deformed after being floated, and stress concentration will occur under the time effect, thus damaging the device, the internal connection device 7 is set to a thick spring with hooks 8 at both ends, so that each steel sheet 6 of the device can be displaced in a small range. This design can greatly increase the efficiency of the device, make the device easy to assemble and disassemble, and increase its tensile strength. In order to prevent the hook 8 from being damaged or broken due to excessive stress concentration, the hook parts at both ends are thickened to extend the service life of the device. The use of a hook-type connection method allows each component to be locally processed and easy to disassemble, greatly saving construction time. At the same time, its detachable performance also increases the reuse rate of the device, saves economic costs, and better meets market requirements.

[0021] The external locking sleeve 9 serves as the framework for the internal connection device 7, with multiple semicircular steel rings welded to it. After the steel sheets 6 are arranged into a single unit, the internal pipeline fixing portion is attached to the semicircular steel rings on the external locking sleeve 9 using a thick spring. In addition to serving as the framework for the internal connection device 7, the external locking sleeve 9 also serves as a fixing mechanism. Holes are provided on the left and right sides and bottom of the external locking sleeve 9 for connecting to an anchoring device. The anchoring device includes an anchor rod 4 with a connecting ring 5 welded to the end of the anchor rod 4. The connecting ring 5 passes through the holes to connect the external locking sleeve 9 to the anchoring device.

[0022] The internal pipe fixings are preferably made of iron to provide additional counterweight. Anti-floating locks are placed approximately every 5 meters. When the concrete is poured to encapsulate the pipes, their own weight can be used to press down the buoyant pipes. The internal connection device 7 and external locking sleeve 9 are made of special waterproof steel to increase their resistance to wear and corrosion.

[0023] The present invention preferably adopts an overall rectangular configuration, with a large gap between the rectangular outer locking sleeve 9 and the internal pipeline fixing portion. The steel sheets 6 are arranged in a rectangular pattern, also with large gaps. This design facilitates the passage of concrete through the gaps during pouring, allowing the concrete to quickly submerge the pipe, thereby reducing the buoyancy experienced by the pipe.

[0024] The outer lock sleeve 9, the inner pipeline fixing part and the inner connecting device 7 of the anti-floating lock are tightly connected, and the disassembly and installation are convenient. If relevant improvements are made later, the scheme can have good feasibility in the experiment.

[0025] The end of the anchoring device is composed of an anchor head 1, a spring 3, and a gasket 2. The economic cost is low. The anchor head 1 is arrow-shaped, which allows the anchoring device to be easily inserted into the soil. The anchor head 1 is hollow inside, and the gasket 2 is welded inside the anchor head 1. The spring 3 is welded to the other end of the gasket 2, and the bottom end of the spring 3 is welded to the anchor head 1. The anchor head 1 is connected to the anchor rod 4 by a thread. The end of the anchoring device uses a friction self-locking principle similar to that of an expansion bolt. The spring 3 and gasket 2 in the anchoring device cause the device to form friction when subjected to outward tension, achieving self-locking, and anchoring the entire anti-floating lock including the pipeline in the soil at both ends and the bottom of the pipeline trough. This can prevent the pipeline from floating due to concrete pouring when concrete is poured; and prevent the pipeline from being washed out of its original position by seepage water due to the high groundwater level when backfilling with plain soil, causing the pipeline to be dislocated and damaged.

[0026] The preferred embodiments of the present application are described in detail above, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of the present application.
