Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a temporary protective structure for a prefabricated hollow pipe pile head. Background Art

[0002] Prestressed concrete pipe piles have the advantages of high bearing capacity, economy, environmental protection, reliable construction quality, convenience and speed, and are widely used in engineering construction. There will be a period of time between the prestressed concrete pipe piles being pressed into place and the next step of the subsequent core pouring construction. In order to prevent mud, water or other construction waste from entering the pipe pile core through the hollow of the pile head, the pile head needs to be temporarily blocked.

[0003] At present, the domestic construction industry generally uses sandbags for temporary blocking to prevent the pile head from entering the soil. However, the surface of the sandbag is easily scratched and the quality is difficult to control by marking, so the temporary protection effect cannot be achieved. When the pile head elevation needs to be sent underground, temporary blocking cannot be performed, causing the soil, water or other garbage around the pile head to slide into the interior of the pile from the hollow of the pile head, seriously affecting the subsequent pile core filling construction efficiency and the quality of the core filling concrete pouring. Utility Model Content

[0004] Based on the above description, the utility model provides a temporary protective structure for the pile head of a prefabricated hollow pipe pile to solve the problem of poor protective effect of using sandbags for temporary blocking to prevent the pile head from entering the soil.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] The present application provides a temporary protective structure for the head of a prefabricated hollow pipe pile, and the technical solution adopted is as follows:

[0007] A temporary protective structure for a prefabricated hollow pipe pile head, comprising:

[0008] A protective plug is arranged in the pipe pile and located at the mouth of the pipe pile;

[0009] A sealing gasket, which is arranged between the protective plug and the pipe pile, and is suitable for squeezing the sealing gasket through the protective plug to deform the sealing gasket, so as to form a seal between the pipe pile and the protective plug;

[0010] A limiting structure is connected to the protection plug and is used to limit the protection plug from moving axially into the pipe pile.

[0011] Preferably, the protective plug is cylindrical and coaxial with the pipe pile, the sealing gasket is arranged outside the protective plug, and the sealing gasket is in contact with the inner wall of the pipe pile on all sides.

[0012] Preferably, the sealing gasket is bonded to the inner wall of the pipe pile.

[0013] Preferably, the lower end of the protective plug is configured to be in the shape of a truncated cone with a diameter gradually decreasing toward the lower end.

[0014] Preferably, a groove is provided on the upper end surface of the protective plug, a driving plate connected to the protective plug is provided in the groove, the plane of the driving plate is parallel to the axis of the protective plug, and is suitable for driving the protective plug to rotate around its axis by operating the driving plate.

[0015] Preferably, the limiting structure includes a limiting plate connected to the upper end of the protective plug, the plane of the limiting plate is perpendicular to the axis of the protective plug, and the limiting plate covers the pile mouth, and an operating hole is opened on the limiting plate, which is suitable for operating the driving plate through the operating hole.

[0016] Preferably, the protective plug is provided with an air outlet hole, the air outlet hole penetrates the protective plug at both ends in the axial direction, and the protective plug is connected with an air hole plug for blocking or opening the air outlet hole.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0018] 1. The present application sets a protective plug and a sealing gasket. The protective plug is inserted into the pipe pile and a sealing gasket is set between the protective plug and the pipe pile. The sealing gasket is squeezed by the protective plug to deform the sealing gasket, so that a seal is formed between the pipe pile and the protective plug. During construction, the sealing coil is first set in the pipe pile and fits the inner wall of the pipe pile on all sides. Then the protective plug is inserted into the sealing gasket to squeeze the sealing gasket and deform it, so that the sealing gasket fills the gap between the protective plug and the pipe pile, thereby achieving a seal between the protective plug and the pipe pile and achieving closed construction of the pipe pile mouth. At the same time, a limiting structure is connected to the protective plug to limit the axial movement of the protective plug into the pipe pile, so that the protective plug is kept at the pile mouth and the subsequent removal of the protective plug is convenient. Therefore, the protective structure of the present application has good protective effect, simple structure, convenient construction and can be reused.

[0019] 2. The present application makes it easy to insert the protective plug into the pipe pile and the sealing gasket by setting the protective plug into a cylindrical shape. At the same time, the lower end of the protective plug is set to a truncated cone shape, which makes it easier to insert the protective plug into the sealing gasket, thereby improving construction efficiency. The setting of the driving plate facilitates the rotation of the protective plug during construction to quickly install it in place, further improving work efficiency.

[0029] Reference Figure 1-2 As shown, an embodiment of the present application provides a temporary protective structure for the head of a prefabricated hollow pipe pile, including a protective plug 2, a sealing gasket 3 and a limiting structure. The protective plug 2 is arranged in the pipe pile 1 and is located at the pile mouth of the pipe pile 1. The sealing gasket 3 is arranged between the protective plug 2 and the pipe pile 1, and is suitable for squeezing the sealing gasket 3 through the protective plug 2 to deform the sealing gasket 3 so as to form a seal between the pipe pile 1 and the protective plug 2. The limiting structure is connected to the protective plug 2 and is used to limit the protective plug 2 from moving axially into the pipe pile 1.

[0030] Reference Figure 1-2 As shown, specifically, the protective plug 2 is set to be cylindrical, and its diameter is smaller than the inner diameter of the pipe pile 1. Correspondingly, the sealing gasket 3 is set to be cylindrical and coaxial with the pipe pile 1. The sealing gasket 3 is arranged outside the protective plug 2, and the sealing gasket 3 is in contact with the inner wall of the pipe pile 1. The inner diameter of the sealing gasket 3 in the undeformed state is smaller than the diameter of the protective plug 2, so that the sealing gasket 3 can be squeezed to deform when the protective plug 2 is inserted into the sealing gasket 3. During construction, the adhesive material is applied to the inner wall of the pipe pile 1, and the sealing gasket 3 is placed in the area of ​​the pipe pile 1 where the adhesive material is applied, and the sealing gasket 3 is in contact with the inner wall of the pipe pile 1. The sealing gasket 3 is bonded to the inner wall of the pipe pile 1 through the adhesive material, and then the protective plug 2 is inserted into the pipe pile 1 and the sealing gasket 3, and the sealing gasket 3 is squeezed to deform until the protective plug 2 is completely inserted into the sealing gasket 3. The pile mouth of the pipe pile 1 is blocked and sealed by the sealing gasket 3 and the protective plug 2, thereby playing a temporary protective function for the pile head of the pipe pile 1.

[0031] Reference Figure 1-2 As shown, during construction, in order to facilitate the insertion of the protective plug 2 into the pipe pile 1 to which the sealing gasket 3 is bonded, the lower end of the protective plug 2 is set to be a truncated cone with a diameter gradually decreasing near this end, and the minimum diameter is smaller than the inner diameter of the sealing gasket 3 in the undeformed state. In this way, when installing the protective plug 2, the lower end of the protective plug 2 can be inserted into the sealing gasket 3 first, and then the protective plug 2 can continue to be inserted into the sealing gasket 3 and drive the sealing gasket 3 to deform until the protective plug 2 is installed in place.

[0032] Reference Figure 1-2As shown, further, a groove is provided on the upper end surface of the protective plug 2, and a driving plate 21 connected to the protective plug 2 is provided in the groove, and the plane of the driving plate 21 is parallel to the axis of the protective plug 2, and is suitable for driving the protective plug 2 to rotate around its axis by operating the driving plate 21. When the protective plug 2 is inserted into the pipe pile 1, directly pressing the protective plug 2 into the pipe pile 1 along the axial direction requires a large pressure and easily causes the sealing gasket 3 to be misplaced, so the driving plate 21 is provided on the protective plug 2, and the driving plate 21 facilitates personnel to apply a force to drive the protective plug 2 to rotate around the axis, so that the protective plug 2 is rotated and inserted into the sealing gasket 3, further facilitating the installation of the protective plug 2.

[0033] Reference Figure 1-2 As shown, further, when the protective plug 2 is inserted into the pipe pile 1, in order to balance the pressure inside and outside the pipe pile 1 so that the protective plug 2 can be installed in place, an air outlet 22 is opened on the protective plug 2, and the air outlet 22 is connected at both ends of the axial direction of the protective plug 2. When the protective plug 2 is inserted into the pipe pile 1, the air in the pipe pile 1 can be discharged from the air outlet 22, thereby avoiding the increase of the pressure inside the pipe pile 1 and hindering the installation of the protective plug 2. In addition, the protective plug 2 is connected with an air hole plug for blocking or opening the air outlet 22. When the protective plug 2 is installed, the air hole plug is opened. After the protective plug 2 is installed in place, the air outlet 22 is blocked by the air hole plug, thereby completely sealing the pile head of the pipe pile 1.

[0034] Reference Figure 1-2 As shown, further, in order to prevent the protective plug 2 from falling into the pipe pile 1, the protective plug 2 is connected to a limiting structure, which includes a limiting plate 4, which is connected to the upper end of the protective plug 2, the plane of the limiting plate 4 is perpendicular to the axis of the protective plug 2, and the limiting plate 4 covers the pile opening of the pipe pile 1; correspondingly, an operation hole 41 is opened on the limiting plate 4 to expose the driving plate 21 and the air outlet 22, so that personnel can operate the driving plate 21 through the operation hole 41 to rotate the protective plug 2. After the protective plug 2 is installed in place, the limiting plate 4 covers the pile opening of the pipe pile 1, thereby limiting the protective plug 2 from continuing to move into the pipe pile 1 through the limiting plate 4, preventing the protective plug 2 from falling into the pipe pile 1, and at the same time facilitating the removal of the protective plug 2 from the pipe pile 1 for reuse.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
