Description

Technical Field

[0001] This utility model relates to the field of bridge pile foundation technology, and in particular to a pressurizable valve-type steel pipe maintenance mold. Background Technology

[0002] In the field of bridge pile foundation construction, especially in deep water pile foundation construction, steel casings play a crucial role. During the drilling and concrete pouring stages, steel casings can effectively seal the mud, ensure the stability of the water level in the hole, restrain the surrounding soil and the concrete mixture in the hole, and maintain the stability of the construction environment. After construction, with the help of the steel pipe's confinement effect on the concrete, the core concrete can be placed in a triaxial compression state, significantly improving the compressive strength and compressive deformation capacity of the core concrete, thereby enhancing the stability and bearing capacity of the entire pile foundation structure.

[0003] In the construction of bridges, buildings, and mining platform foundations in rivers, oceans, and other water bodies, the use of steel casings is enormous. However, research on the recycling technology of deep-water steel casings is currently crucial. On the one hand, the rational recycling of steel casings can reduce environmental pollution caused by discarded casings; on the other hand, this aligns with the contemporary requirements of energy conservation and environmental protection, effectively reducing engineering costs and providing important support for the sustainable use of resources. Existing technologies, such as the underwater temperature-controlled, self-balancing pressure-curing device for concrete (publication number CN118774039A), employ a self-balancing pressure-pressurized valve-type steel pipe curing mold. This mold, through the coordinated structure of a base plate, bottom plug, mold components, top plug, top plate, screw, tension sensor, and locking nut, can perform self-balancing pressure curing of concrete, simulating curing conditions at different depths. This helps workers better understand the characteristics of underwater concrete construction, allowing for the disassembly and recycling of the steel casings used in underwater construction at the appropriate time.

[0004] However, this mold has obvious shortcomings in practical applications. When disassembling and installing the steel casings, in order to successfully remove multiple steel casings, the top plate, tension sensor and locking nut need to be completely disassembled. When conducting the experiment again, the staff must reinstall these components. This series of operations not only increases the number of work steps and consumes a lot of time and manpower, but also reduces the efficiency of the experiment.

[0005] Therefore, it is necessary to provide a pressurizable valve-type steel pipe maintenance mold to solve the above-mentioned technical problems. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0025] Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic diagram of the structure of the first embodiment of a pressurizable valve-type steel pipe maintenance mold provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the base plate and the top plate. Figure 3 for Figure 2The enlarged schematic diagram of part A is shown. A pressurizable valve-type steel pipe maintenance mold includes: a base plate 1, a top plate 2, a steel casing 3, a support frame 6, a limiting frame 7, and a pressing component 8. The base plate 1 and the top plate 2 are respectively disposed at the bottom and top of the steel casing 3. The bottom of the support frame 6 is fixedly installed on the top of the base plate 1. The top plate 2 is slidably connected to the outer side of the support frame 6. The limiting frame 7 is fixedly installed on the top of the top plate 2. The pressing component 8 is disposed on the top of the top plate 2.

[0026] The pressing assembly 8 includes a threaded sleeve 81, a rotating handle 82, a threaded rod 83, a limiting plate 84, and a tension sensor 85. The rotating handle 82 is fixedly installed on the outer side of the threaded sleeve 81, the threaded rod 83 is threadedly connected to the inside of the threaded sleeve 81, the limiting plate 84 is fixedly installed on the bottom of the threaded rod 83, and the tension sensor 85 is fixedly installed on the bottom of the limiting plate 84.

[0027] The bottom plate 1 is provided with a bottom plug 4 at its top, and the top plate 2 is provided with a top plug 5 at its bottom. The top of the bottom plug 4 and the bottom of the top plug 5 are respectively located inside the bottom and top of the steel casing 3.

[0028] The top of the limiting frame 7 is provided with a through hole 71, and the threaded rod 83 is disposed on the inner side of the through hole 71.

[0029] The limiting plate 84 is disposed at the bottom of the through hole 71, and the diameter of the limiting plate 84 is larger than the diameter of the through hole 71.

[0030] The threaded sleeve 81 is rotatably connected to the inside of the top of the support frame 6.

[0031] When the top plate 2 moves up and down, the top plate 2 will slide on the outer side of the support frame 6, thereby limiting the top plate 2 and ensuring that when the top plate 2 moves down, the top plug 5 can accurately abut against the top of the steel casing 3.

[0032] When the top plate 2 drives the top plug 5 to press against the top of the steel casing 3, the bottom of the tension sensor 85 will abut against the top of the top plate 2, thereby measuring the downward pressure.

[0033] The diameter of the limiting plate 84 is larger than that of the through hole 71. This way, when the threaded rod 83 moves upward, it can drive the bottom of the limiting plate 84 to abut against the top of the inner side of the limiting frame 71 and move upward.

[0034] A square rod is slidably connected inside the bottom of the limiting plate 84. The bottom of the square rod is fixedly installed on the top of the top plate 2. This can limit the threaded rod 83 to the top of the top plate 2, preventing the threaded rod 83 from rotating. When the threaded rod 83 moves up and down, the top of the square rod will slide inside the limiting plate 84.

[0035] The working principle of the pressurizable valve-type steel pipe maintenance mold provided by this utility model is as follows:

[0036] When using it, the user first installs the bottom plug 4 on the top of the base plate 1, then puts the steel sleeve 3 on the outer side of the bottom plug 4, and then pours concrete into the inner side of the steel sleeve 3. Then the user rotates the handle 82, which causes the handle 82 to drive the threaded sleeve 81 to rotate inside the top of the support frame 6, and the threaded sleeve 81 to be threaded on the outer side of the threaded rod 83. At this time, the threaded rod 83 will move downward, causing the top plate 2 to drive the top plug 5 to press on the top of the steel sleeve 3.

[0037] When demolding, the user only needs to reverse the handle 82. At this time, the threaded rod 83 will move upward and the bottom of the limiting plate 84 will abut against the top of the inner side of the limiting frame 7, thereby driving the top plate 2 to move upward until the bottom of the top plug 5 is above the top of the steel casing 3. Then the user can demold the steel casing 3.

[0038] Compared with related technologies, the pressurizable valve-type steel pipe maintenance mold provided by this utility model has the following beneficial effects:

[0039] By cooperating with each other, the support frame 6, the limiting frame 7 and the pressing component 8 can be used without completely disassembling the top plate 2. Simply by rotating the handle 82 to drive the threaded sleeve 81 to make a threaded connection on the outer side of the threaded rod 83, the pressing and demolding operations of the steel casing 3 can be realized, reducing the number of working steps and improving work efficiency.

[0041] Specifically, the second embodiment of this application provides a pressurizable valve-type steel pipe maintenance mold that differs in that the pressurizable valve-type steel pipe maintenance mold further includes a protrusion 9, a groove 10, and a magnetic plate 101. The protrusion 9 is fixedly installed on the top of the bottom plate 1 and the bottom of the top plate 2, respectively. The groove 10 is respectively opened on the bottom of the bottom plug 4 and the top of the top plug 5. The magnetic plate 101 is fixedly installed on the inner side of the groove 10.

[0042] The protrusion 9 is disposed on the inner side of the groove 10, and the magnetic plate 101 and the protrusion 9 are magnetically connected.

[0043] The working principle of the pressurizable valve-type steel pipe maintenance mold provided by this utility model is as follows:

[0044] When installing the bottom plug 4 and the top plug 5, simply align the grooves 10 on the bottom plug 4 and the top plug 5 with the protrusions 9 on the top plate 2 and the bottom plate 1, and then insert the protrusions 9 into the inner side of the grooves 10 so that the magnetic plate 101 and the protrusions 9 are magnetically attracted, thus installing the bottom plug 4 and the top plug 5.

[0045] Compared with related technologies, the pressurizable valve-type steel pipe maintenance mold provided by this utility model has the following beneficial effects:

[0046] The top plug 5 and bottom plug 4 are installed by the cooperation of the protrusion 9, the groove 10 and the magnetic plate 101. When in use, the protrusion 9 is simply inserted into the inner side of the groove 10 and the magnetic plate 101 and the protrusion 9 are magnetically attracted to each other. This makes the operation convenient and quick and increases work efficiency.
