Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated walls, and specifically relates to a slurry leakage-proof rubber plug. Background Art

[0002] It is difficult to control the fullness of grouting in prefabricated wall and column sleeves: currently, the grouting of prefabricated component sleeves mainly uses closed rubber plugs to seal the slurry outlet holes and grouting holes. The method used for grouting holes in actual construction is: after taking out the grouting pipe, it is sealed with a closed rubber plug. There is a time gap during manual operation, and the grouting material will overflow under the action of its own weight, which can easily cause the slurry in the prefabricated wall and column sleeves to be incomplete, affecting the safety of the structure.

[0003] The prior art lacks a rubber plug that cooperates with the grouting pipe to solve the problem that when the closed rubber plug of the prior art completes the grouting hole, the slurry in the prefabricated wall and column sleeve is not full, thus affecting the safety of the overall structure. Utility Model Content

[0004] The purpose of the utility model is to provide a grout-proof rubber plug to solve the above shortcomings, so as to solve the problem that the prior art lacks a rubber plug that matches the grouting pipe, and solves the problem that when the closed rubber plug completes the grouting hole, the grout in the prefabricated wall and column sleeve is not full, thus affecting the safety of the overall structure. To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A slurry leakage prevention rubber plug is used to block a grouting hole, comprising a blocking part and a sealing part; the blocking part is used to be in close contact with the inner wall of the grouting hole; the sealing part cooperates with the blocking part to achieve slurry blocking; a slurry circulation channel is provided in the blocking part; the sealing part is squeezed by the slurry to form a one-way circulation channel for slurry circulation.

[0006] Furthermore, the blocking portion is a truncated cone plug; the diameter of the upper bottom surface of the truncated cone plug is smaller than the diameter of the lower bottom surface; a through hole is provided in the truncated cone plug; the through hole passes through the upper bottom surface of the truncated cone plug to the lower bottom surface.

[0007] Furthermore, the sealing portion is a disc plug; the disc plug is cooperatively connected with the bottom surface of the truncated cone plug.

[0008] Furthermore, a cylindrical protrusion is provided on the disc plug; the diameter of the cylindrical protrusion is consistent with the through hole, and cooperates with the through hole to close the truncated cone plug; one end of the cylindrical protrusion gradually becomes thinner from the edge to the center of the circle, and is cut at the center to form a cross-shaped crack.

[0009] Furthermore, the cross-shaped crack runs through the cylindrical protrusion and the disc plug.

[0010] Furthermore, two support rods are provided inside the truncated cone plug; the two support rods are arranged in a cross shape.

[0011] Further two support rods are arranged corresponding to the cross-shaped cracks.

[0012] Furthermore, an annular limiting groove is provided on the outer side surface of the truncated cone plug.

[0013] Furthermore, the truncated cone plug is made of rubber material.

[0014] Furthermore, the disc plug is made of rubber material.

[0015] The beneficial effects of the utility model are:

[0016] 1. The utility model provides a grout-proof rubber plug, the internal through hole of which cooperates with a grouting pipe, and the grouting material sprayed out of the grouting pipe squeezes the cross-shaped crack on the disc plug to form a channel to fill the grouting material. When the grouting material is filled, the grouting is stopped, and the disc plug is subjected to the pressure generated by the deadweight of the slurry in the prefabricated wall and column sleeve, so that the cross-shaped crack on the disc plug recovers its deformation, and the setting of the support rod can prevent the cross-shaped crack from continuing to open in the opposite direction after recovering its deformation, thereby closing the channel and completing the blocking;

[0017] 2. The utility model provides a slurry leakage prevention rubber plug, which does not need to be plugged after the grouting pipe is completed. Instead, it is installed in conjunction with the grouting pipe at the beginning of grouting. After the grouting is completed, the grouting pipe is removed to complete the plugging. Excessive overflow of slurry due to time gaps will not be caused, ensuring that the slurry is fully filled and the structure is stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the present invention is not limited to the following embodiments.

[0024] Embodiment 1:

[0025] See attached Figures 1 to 4. A slurry leakage prevention rubber plug, used for plugging a grouting hole, comprises a blocking part and a sealing part; the blocking part is used for being in close contact with the inner wall of the grouting hole; the sealing part cooperates with the blocking part to achieve the blocking of the slurry; a slurry circulation channel is provided in the blocking part; the sealing part is squeezed by the slurry to form a one-way circulation channel for the circulation of the slurry. From the above structure, it can be seen that the utility model is a slurry leakage prevention rubber plug, which consists of a blocking part and a sealing part. The blocking part is made of rubber material and is in the shape of large and small heads. The small head is inserted into the grouting hole until the outer wall of the blocking part is in close contact with the inner wall of the grouting hole to form a blockage. A channel is provided inside the blocking part, which cooperates with the grouting pipe and is used for the circulation of slurry in the grouting pipe. The sealing part cooperates with the small head end of the blocking part to seal the channel to ensure that the slurry does not flow out. The channel in the rubber plug formed by the blocking part and the sealing part is a one-way channel, that is, the slurry can only enter the interior of the prefabricated wall through the channel, but cannot flow out from the inside. The specific sealing part is also made of rubber material. During the processing, a cross crack is formed on the sealing part toward one end of the channel, and the thickness gradually increases from the center to the outside. The cross crack runs through the sealing part. After the grouting pipe is well connected to the channel, slurry is injected into the grouting hole. The pressure generated by the slurry can open the cross crack into the grouting hole to form a channel to complete the filling of the slurry. After the grouting is completed, the grouting pipe stops grouting and is removed from the channel. At this time, the cross crack is The cracks will be subjected to the pressure generated by the weight of the slurry in the grouting hole, which will cause the cross cracks to open out of the grouting hole. The structure of the sealing part itself, that is, the end facing the grouting hole is set in a plane as a whole, and the thickness of the end facing the outside of the grouting hole gradually increases from the center to the edge, to ensure that the pressure required for the cross crack to open in the grouting hole is much less than the pressure required to open out of the grouting hole, and a cross support rod is set at the position corresponding to the cross crack position on the channel in the blocking part. The cross support rod further blocks the cross crack from opening out of the grouting hole, ensuring that only a one-way channel is formed at the cross crack for slurry filling of the grouting pipe. After the grouting is completed, the moment the grouting pipe is removed, that is, the moment the cross crack is closed, the slurry is blocked, there is no time gap in the middle, and there will be no excessive slurry overflow, ensuring that the slurry is fully filled and the structure is stable after solidification.

[0026] Embodiment 2:

[0027] See attached Figures 1 to 4. On the basis of the first embodiment, the blocking part is a truncated cone plug 1; the diameter of the upper bottom surface of the truncated cone plug 1 is smaller than the diameter of the lower bottom surface; a through hole 2 is provided in the truncated cone plug 1; the through hole 2 penetrates from the upper bottom surface of the truncated cone plug 1 to the lower bottom surface. It can be seen from the above structure that, specifically, the blocking part is a truncated cone plug 1, the truncated cone plug 1 is in a shape of being small on the top and large on the bottom as a whole, and is circular in cross section in conjunction with the grouting hole. The upper bottom surface of the truncated cone plug 1 is used to be inserted into the grouting hole until the outer wall of the truncated cone plug 1 is in complete and tight contact with the inner wall of the grouting hole. The truncated cone plug 1 is made of rubber material and has sufficient friction to prevent the truncated cone plug 1 from falling off the grouting hole. A through hole 2 is provided in the truncated cone plug 1, and the through hole 2 penetrates from the upper bottom surface of the truncated cone plug 1 to the lower bottom surface, and is used to cooperate with the grouting pipe to form a circulation channel for the slurry.

[0028] The sealing part is a disc plug 3; the disc plug 3 is connected with the upper bottom surface of the truncated cone plug 1. As can be seen from the above structure, the specific sealing part is a disc plug 3, whose diameter is equivalent to the upper bottom surface diameter of the truncated cone plug 1, and the disc plug 3 is also made of rubber material. The disc plug 3 is connected with the upper bottom surface of the truncated cone plug 1, and can be fixedly connected by hot melt or strong glue to close the channel in the truncated cone plug 1 to prevent slurry from overflowing.

[0029] Embodiment three:

[0030] See attached Figures 1 to 4 . On the basis of the second embodiment, a cylindrical protrusion 4 is provided on the disc plug 3; the diameter of the cylindrical protrusion 4 is consistent with that of the through hole 2, and cooperates with the through hole 2 to close the truncated cone plug 1; one end of the cylindrical protrusion 4 gradually thins from the edge to the center of the circle, and is cut off at the center to form a cross-shaped crack 5. From the above structure, it can be seen that a cylindrical protrusion 4 is provided on the disc plug 3, and the cylindrical protrusion 4 is consistent with the diameter of the through hole 2 inside the truncated cone plug 1, and cooperates with the bottom surface of the truncated cone plug 1 to seal the slurry channel. In order to ensure that the slurry only flows in one direction from the outside of the grouting hole to the inside in the channel, the end face of the cylindrical protrusion 4 facing the outside of the grouting hole gradually thins from the edge to the center of the circle, and finally cuts on the cylindrical protrusion 4 to form a cross-shaped crack 5. When the end face is subjected to the pressure of the grouting material sprayed from the grouting pipe, the cross-shaped crack 5 will open into the grouting hole to form a channel for the slurry to flow.

[0031] The cross-shaped crack 5 penetrates the cylindrical protrusion 4 and the disc plug 3. As can be seen from the above structure, the cross-shaped crack 5 penetrates the disc plug 3 and the cylindrical protrusion 4, and a channel is formed when the grouting pipe is grouting. The cross-shaped crack 5 is arranged in a plane together with the disc plug 3 at the end facing the grouting hole, and the end of the cross-shaped crack 5 facing the outside of the grouting hole is arranged to be gradually thinned from the outside to the inside, and the pressure required to open the cross-shaped crack 5 into the grouting hole is much smaller than the pressure required to open it outside the grouting hole in conjunction with the structure of the cylindrical protrusion 4, ensuring that the pressure generated by the grouting pipe during the grouting process can smoothly open the cross-shaped crack 5 into the grouting hole. At the same time, after the grouting is completed, the pressure generated by the slurry inside the grouting hole is not enough to open the cross-shaped crack 5 outside the grouting hole, thereby causing the slurry to overflow.

[0032] Two support rods 6 are arranged inside the truncated cone plug 1; the two support rods 6 are arranged in a cross shape. As can be seen from the above structure, the two support rods 6 arranged inside the truncated cone plug 1 are arranged in a cross shape, and when the through hole 2 is provided in the truncated cone plug 1, the overall support and stability of the truncated cone plug 1 can be enhanced.

[0033] The two support rods 6 are arranged corresponding to the cross-shaped cracks 5. As can be seen from the above structure, the two support rods 6 are arranged in a cross shape and correspond to the positions of the cross-shaped cracks 5, forming a blocking effect, further preventing the cross-shaped cracks 5 from opening outside the grouting hole.

[0034] Embodiment 4:

[0035] See attached Figures 1 to 4 On the basis of the third embodiment, the outer side of the truncated cone plug 1 is provided with an annular limiting groove 7. As can be seen from the above structure, an annular limiting groove 7 is provided on the outer side of the truncated cone plug 1, and the width of the annular limiting groove 7 is consistent with the length of the grouting hole. The annular limiting groove 7 is clamped at the grouting hole, which further increases the friction between the truncated cone plug 1 and the grouting hole, prevents the truncated cone plug 1 from falling off, and increases stability.

[0036] The truncated cone plug 1 is made of rubber material. As can be seen from the above structure, the truncated cone plug 1 is made of a rubber material with toughness. When it is matched with the grouting hole, its upper bottom surface can be easily inserted into the grouting hole until the truncated cone plug 1 is closely fitted with the grouting hole at the place where the diameter of the lower bottom surface is larger as it approaches the truncated cone plug 1. Further pressure is applied, and the tough rubber material can further insert the truncated cone plug 1 into the grouting hole, and the friction force generated will also be greater, so the whole is more stable and not easy to fall off.

[0037] The disc plug 3 is made of rubber material. As can be seen from the above structure, the disc plug 3 and the cylindrical protrusion 4 are both made of rubber material, which has certain toughness and recovery, ensuring that the cross-shaped crack 5 always has the recovery to maintain a closed state. At the same time, the disc plug 3 and the truncated cone plug 1 are both made of rubber toughness material. When fixedly connected, they can be connected as a whole by hot melting, and the structure is more stable.

[0038] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
