Description

Technical Field

[0001] This application relates to the technical field of barrel structures, specifically to the slurry stop strip at the bottom of a large round barrel. Background Art

[0002] The barrel foundation structure is a lightweight structure suitable for silty soil foundations with low bearing capacity. Its stability calculation relies on the interaction between the barrel and the soil to resist external loads. Therefore, earth pressure is the core content of the stability calculation of the barrel foundation structure.

[0003] The barrel foundation structure is generally a single-barrel multi-compartment precast concrete structure. The barrel foundation structure consists of a foundation cylinder and an upper structure. The foundation cylinder is composed of a barrel body, a cover plate, and a partition plate. The upper structure can be flexibly designed according to the requirements of the use function.

[0004] Affected by the earth pressure on the cylinder, to ensure that there is no slurry leakage in the cylinder, a slurry stop strip needs to be set at the first layer position of the lower barrel of the barrel foundation structure. Currently, the slurry stop strip is mostly made of rubber, and the size of the dovetail mouth of the slurry stop strip is also customized individually. Therefore, the current size of the slurry stop strip needs to match the size of the round barrel structure, and then it can be fixed on the round barrel under the elastic force of the slurry stop strip itself. Therefore, the applicability of the slurry stop strip is relatively single, and its applicable size is certain when its deformation amount does not change. For this, a slurry stop strip at the bottom of a large round barrel is proposed to solve the above problems. Utility Model Content

[0005] In view of the deficiencies of the prior art, this application provides a slurry stop strip at the bottom of a large round barrel, which has the advantages of being able to change the deformation amplitude of the slurry stop strip itself and increasing the applicable size range of the slurry stop strip.

[0006] To achieve the above object, this application provides the following technical solution: A slurry stop strip at the bottom of a large round barrel, including a slurry stop strip and a round barrel for loading the slurry stop strip. An afterbridge extends integrally on the slurry stop strip, and a support structure is arranged in the inner cavity of the afterbridge;

[0007] The support structure includes a fixing plate fixedly installed on the inner wall of the afterbridge and a support plate slidably connected to the fixing plate. A threaded rod is rotatably installed in the middle of the fixing plate, a threaded sleeve is threadedly installed on the outside of the threaded rod, and a support rod is rotatably installed between the threaded sleeve and the two support plates on both sides.

[0008] Further, a groove is opened on one side surface of the slurry stop strip facing the round barrel, and the groove corresponds to the round barrel.

[0009] Further, the whole afterbridge protrudes outward in a U shape towards the outside of the slurry stop strip.

[0010] Further, a dovetail block is integrally extended at one end of the support plate facing the fixed plate. A limiting groove for the sliding connection of the support plate is formed on the surface of the fixed plate, and the dovetail block is slidably connected to the limiting groove.

[0011] Further, a bearing is rotatably installed in the middle of the fixed plate, and the threaded rod is fixedly connected to the bearing.

[0012] Further, a connecting seat is installed in the middle of the support plate and is rotatably connected to one end of the support rod, and the other end of the support rod is rotatably connected to the threaded sleeve.

[0013] Further, the overall cross-section of the grout stop strip is dovetail-shaped and expands outward away from the direction of the barrel.

[0014] Further, a limiting block is fixedly installed at the end of the threaded rod, and the limiting block is regular hexagon.

[0015] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0016] For the grout stop strip at the bottom of the large barrel, by setting the grout stop strip to adopt a dovetail structure and being snap-fitted and installed through its own elastic force, and at the same time adding a rear bridge at the dovetail end, and installing a support rod and a support plate in the rear bridge to change the deformation amplitude of the rear bridge, so that the grout stop strip can adaptively change and adjust when there is a certain deviation between the groove width and the size of the barrel, thereby improving the applicability of the grout stop strip.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0023] Please refer to Figures 1 to 4 , the slurry stopping strip at the bottom of the large barrel in this embodiment includes a slurry stopping strip 1 and a barrel 2 for loading the slurry stopping strip 1. The overall cross-section of the slurry stopping strip 1 is in a dovetail shape and expands outward away from the barrel 2.

[0024] In this embodiment, a groove 101 is provided on one side surface of the slurry stopping strip 1 facing the barrel 2. The groove 101 is connected corresponding to the cover plate structure of the barrel 2. A rear bridge 102 extends integrally on the side surface of the slurry stopping strip 1 away from the groove 101.

[0025] It should be noted that the overall shape of the rear bridge 102 is U-shaped and protrudes towards the outside of the slurry stopping strip 1. Such a design enables the two dovetail parts on both sides of the slurry stopping strip 1 to obtain a larger deformation space under extrusion, thereby improving the applicability of the slurry stopping strip 1.

[0026] In order to support the slurry stopping strip 1, a support structure is provided in the inner cavity of the rear bridge 102 in this embodiment to limit the deformation of the rear bridge 102. The support structure includes a fixing plate 3 fixedly installed on the inner wall of the rear bridge 102 and a support plate 4 slidably connected to the fixing plate 3.

[0027] Among them, the number of the support plates 4 is two, and the two support plates 4 respectively contact the upper and lower inner walls of the rear bridge 102.

[0028] Preferably, a dovetail block 6 extends integrally at one end of the support plate 4 facing the fixing plate 3. A limiting groove 5 for the slidable connection of the support plate 4 is provided on the surface of the fixing plate 3. The dovetail block 6 is slidably connected to the limiting groove 5. Through the setting of the dovetail block 6 and the limiting groove 5, the sliding stability of the support plate 4 relative to the fixing plate 3 can be improved.

[0029] In this embodiment, a threaded rod 8 is rotatably installed in the middle of the fixing plate 3. A threaded sleeve 10 is threadedly installed on the outside of the threaded rod 8. A support rod 11 is rotatably installed between the threaded sleeve 10 and the two support plates 4.

[0030] It should be noted that a bearing 7 is rotatably installed in the middle of the fixing plate 3, and the threaded rod 8 is fixedly connected to the bearing 7 and thus rotatably connected to the fixing plate 3.

[0031] In this embodiment, a connecting seat is installed in the middle of the support plate 4 and is rotatably connected to one end of the support rod 11. The other end of the support rod 11 is rotatably connected to the threaded sleeve 10.

[0032] In a specific implementation, by changing the position of the threaded sleeve 10 on the threaded rod 8, the inclination angle of the support rod 11 relative to the support plate 4 can be adjusted, so that the support plate 4 presses against the rear axle 102.

[0033] In this embodiment, a limit block 9 is fixedly installed at the end of the threaded rod 8. The limit block 9 is regular hexagon. On the one hand, the limit block 9 can prevent the threaded sleeve 10 from detaching from the threaded rod 8, and on the other hand, it can facilitate the rotation of the threaded rod 8 by a tool through the limit block 9.

[0034] The working principle of the above embodiment is as follows:

[0035] By directly buckling the grout stop strip 1 on the barrel 2 through the groove 101, at this time, the threaded rod 8 on one side of the grout stop strip 1 is rotated by using a tool. The threaded rod 8 is in threaded fit with the threaded sleeve 10 under the relative rotation with respect to the fixing plate 3. At this time, the threaded sleeve 10 is restricted by the connection of the two support rods 11 and moves relative to the threaded rod 8. At this time, the support rod 11 rotates between the threaded sleeve 10 and the support plate 4, so that the support rod 11 pushes the support plate 4 to press against the rear axle 102, so that the dovetail part of the grout stop strip 1 can be fully pressed and fixed on the barrel 2, improving the application range of the grout stop strip 1.
