Description

Technical Field

[0001] The utility model relates to the field of pile hole blocking, in particular to a pile hole blocking device. Background Art

[0002] Reinforced concrete precast piles are widely used in construction due to their strong compressive resistance to heavy loads. Existing reinforced concrete precast piles are generally prefabricated in processing plants, and after curing to reach the designed strength, they are transported to the construction site and driven into the soil by a pile driver. After the pile body is driven, before the pile hole construction is carried out, the pile hole generally needs to be sealed to prevent mud, sand, gravel and other debris from falling into the pile hole and affecting the subsequent pile hole construction.

[0003] However, traditional pile hole sealing generally uses wooden plates, steel plates and other plates to directly cover the pile holes, and then covers the plates with soil. The plates and the pile holes cannot be effectively fixed, and the plates are prone to displacement and damage during subsequent construction, resulting in poor sealing effects, low plate turnover rates, and debris entering the pile holes. During subsequent construction in the pile holes, hole cleaning operations are still required, resulting in a waste of manpower and material resources and affecting construction efficiency. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art in that the pile hole sealing effect is poor, waste is caused, and construction efficiency is affected, and to provide a pile hole sealing device.

[0009] The utility model provides a pile hole plugging device that plugs the pile hole by using a cover plate. When in use, by rotating the adjusting handle, the slider on the adjusting rod can be driven to move under the cover plate, thereby expanding or retracting the first support arm relative to the adjusting rod, so that the end of the first support arm can be supported on the inner wall of the pile hole, which plays a role in limiting the cover plate, making it difficult for the cover plate to move, and has a better sealing effect on the pile hole, effectively preventing debris from entering the pile hole and affecting subsequent construction. In addition, the pile hole plugging device is easy to prepare and use, and can be easily recycled to avoid waste. At the same time, by rotating the adjusting handle when in use, the supporting range of the supporter can be adjusted to achieve stable support for the inner walls of pile holes with different inner diameters, thereby expanding the scope of application of the pile hole plugging device.

[0010] Preferably, a supporting portion is provided at one end of the first supporting arm away from the connecting portion, so that the supporting portion fits closely with the inner wall of the pile hole and provides better supporting effect.

[0011] Preferably, the support portion is hinged to the first support arm so that the support portion can rotate relative to the first support arm within a limited angle range, so that the support portion can always keep its side surface away from the first support arm for contact support with the inner wall of the pile hole.

[0012] Preferably, the support portion is provided with an anti-slip structure, which can improve the contact stability between the support and the inner wall of the pile hole, thereby achieving a better supporting effect of the support.

[0014] Preferably, the cover plate is a polygonal plate-shaped structural member. The cover plate of the polygonal plate-shaped structural member can be larger than the pile hole, and can cover the pile hole as a whole, thereby improving the sealing effect.

[0015] Preferably, a limiting groove is provided in the middle of the cover plate, and the adjustment handle is arranged in the limiting groove, so that there is no protruding part on the top of the cover plate, thereby preventing the setting of the cover plate from affecting the normal passage of the construction site.

[0016] Preferably, the connecting portion is provided with two or more first support arms, and the plurality of first support arms are arranged around the connecting portion at equal intervals, and each first support arm is hingedly connected to the second support arm, so as to further improve the support stability through the plurality of first support arms.

[0017] Preferably, the cover is provided with a plurality of pull ring handles to facilitate the movement of the cover through the pull ring handles.

[0018] Preferably, the cover plate is provided with a receiving groove, the pull ring handle is hingedly arranged in the receiving groove, and the pull ring handle can be rotated to be received in the receiving groove, so that the pull ring handle is not likely to form a protruding part on the top surface of the cover plate after being installed, thereby avoiding affecting the normal passage of the construction site.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The utility model provides a pile hole plugging device, which plugs the pile hole with a cover plate.

[0038] Example 1

[0039] like Figure 1-Figure 7 As shown, a pile hole sealing device includes a cover plate 1, an adjusting rod 2 and a supporter 4. A cylindrical connecting portion 11 is provided at the center of the bottom of the cover plate 1. A through hole is also provided in the center of the cover plate 1, which passes through the through hole. An adjusting handle 3 is provided at one end of the adjusting rod 2 located above the cover plate 1. The supporter 4 includes a first supporting arm 41, a second supporting arm 42 and a slider 43. The slider 43 is threadedly connected to the adjusting rod 2. One end of the first supporting arm 41 is hinged to the connecting portion 11 through a pin, and one end of the second supporting arm 42 is hinged to the slider 43 through a pin, and the other end is hinged to the first supporting arm 41 through a pin.

[0040] In one or several embodiments, a support portion 44 is provided at one end of the first support arm 41 away from the connecting portion 11. When in use, the support portion 44 is in contact with the inner wall of the pile hole 7 for support, thereby increasing the contact area with the inner wall of the pile hole 7 and achieving a better support effect.

[0041] In an optional embodiment, the support portion 44 may be a plate-shaped structural member or a block-shaped structural member.

[0042] In an optional embodiment, the support portion 44 is hinged to the first support arm 41 in a limited position. When in use, the support portion 44 is rotated relative to the first support arm 41 within a limited angle range. Under the thrust of the first support arm 41, it can adaptively fit the inner wall of the pile hole 7 and maintain stable contact with the pile hole 7.

[0043] In an optional embodiment, the first support arm 41 may be provided with a groove at the end, and the support portion 44 may be a plate-like structural member. The support portion 44 of the plate-like structural member is provided with a protrusion adapted to the groove on the side close to the first support arm 41. The protrusion is adapted to the groove, and a hinged connection is achieved by a pin shaft passing through the groove and the protrusion. By adjusting the range of the groove, the angle range of relative rotation of the support portion 44 and the first support arm 41 is limited.

[0044] In one or more embodiments, an anti-slip structure 5 is provided on the support portion 44, which can improve the contact stability between the support 4 and the inner wall of the pile hole 7, thereby improving the supporting effect of the support 4.

[0045] In an optional embodiment, the support portion 44 of the plate-like structural member may be provided with an anti-slip structural member 5 on one side of the plate surface. The anti-slip structural member 5 may be a rubber gasket.

[0046] In one or several embodiments, the cover plate 1 is a polygonal plate-shaped structural member, preferably a square, which can cover the pile hole 7 as a whole, improve the sealing effect, and facilitate preparation and storage.

[0047] In one or more embodiments, a limiting groove 12 is provided in the middle of the cover plate 1, and the adjustment handle 3 is disposed in the limiting groove 12. This prevents the top of the cover plate 1 from having a protruding portion, thereby preventing the setting of the cover plate 1 from affecting normal traffic at the construction site.

[0048] In an optional embodiment, when the adjusting rod 2 rotates, the position of the adjusting rod 2 relative to the cover plate 1 remains unchanged, and the adjusting handle 3 remains located in the limiting groove 12 .

[0049] In an optional embodiment, the adjusting rod 2 may include a smooth rod section and a threaded section. The smooth rod section is located in a through hole passing through the cover plate 1 and the connecting portion 11. The limiting piece protruding from the smooth rod section is adapted to the annular groove provided in the through hole, so that when the adjusting handle 3 is rotated, the adjusting rod 2 rotates relative to the cover plate 1 without moving relative to it.

[0050] In an optional embodiment, the limiting member may be a screw, a pin or other structural components that may protrude from the adjusting rod 2 .

[0051] In one or more embodiments, the connecting portion 11 is provided with two or more first support arms 41, which are arranged at equal intervals around the connecting portion 11, and each first support arm 41 is hingedly connected to a second support arm 42. The multiple first support arms 41 can further improve the support stability.

[0052] In an optional embodiment, the number of the first support arms 41 may be three, and the three first support arms 41 are evenly distributed around the connecting portion 11 , forming a triangular stable contact with the pile hole 7 when in use.

[0053] In one or more embodiments, the cover plate 1 is provided with a plurality of pull ring handles 6 to facilitate movement of the cover plate 1 through the pull ring handles 6 .

[0054] In an optional embodiment, a receiving groove 13 is provided on the cover plate 1, and the pull ring handle 6 is hingedly provided in the receiving groove 13, and the pull ring handle 6 can be rotated to be received in the receiving groove 13. After the pull ring handle 6 is provided, it is not easy to form a protruding part on the top surface of the cover plate 1, so as to avoid affecting the normal passage of the construction site.

[0055] In an optional embodiment, there may be two pull-ring handles 6 , which are relatively arranged on both sides of the square cover 1 , so as to facilitate the movement of the cover 1 by symmetrically pulling the two pull-ring handles 6 .

[0056] The pile hole plugging device of this embodiment is characterized in that the cover plate 1 can be a steel structure plate, the adjusting rod 2 can be a screw rod processed part, the first support arm 41 and the second support arm 42 can be steel rod structural parts, and the slider 43 can be a steel ring. The combination of these structures allows the cover plate 1 to plug the pile hole 7 when in use. By rotating the adjusting handle 3, the slider 43 on the adjusting rod 2 below the cover plate 1 can be driven to move, thereby expanding or contracting the first support arm 41 relative to the adjusting rod 2, so that the end of the first support arm 41 can be supported on the inner wall of the pile hole 7, thereby limiting the cover plate 1 and preventing the cover plate 1 from moving easily. This has a better plugging effect on the pile hole 7, achieves rapid plugging of the pile hole 7, improves work efficiency, and effectively prevents debris from entering the pile hole 7 and affecting subsequent construction. The pile hole plugging device is easy to prepare, easy to use, not easy to damage, and can be easily recycled to avoid waste. At the same time, by rotating the adjusting handle 3 when in use, the supporting range of the support 4 can be adjusted to achieve stable support for the inner walls of pile holes 7 with different inner diameters, thereby expanding the scope of application of the pile hole plugging device.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
