Description

Technical Field

[0001] This utility model relates to the field of probing engineering technology, and in particular to a device for sealing probing holes in foundations. Background Technology

[0002] After the excavation of the foundation pit or trench reaches the design elevation, it is necessary to investigate the soil layers below the bottom of the pit or trench to determine the soil strength and uniformity, and to investigate whether there are ancient wells, tombs, cavities, etc., that could affect the bearing capacity or stability of the foundation. In related technologies, this is mainly done through probing. Specifically, a steel probe is used to drill probing holes in the foundation. After drilling, the depth of the holes and the probing records are checked by quality inspectors. After the trench passes inspection, the probing holes are filled with sand. However, during the period from drilling to sand filling, factors such as probe displacement and human disturbance can easily loosen the soil above the probing hole, causing it to fall into the deeper part of the hole. Furthermore, external debris can easily enter the probing hole, potentially causing blockage and affecting inspection and acceptance. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] The following is combined Figure 1 This invention describes a foundation borehole sealing device.

[0028] like Figure 1 As shown, this utility model provides a foundation borehole sealing device 1, including: a cylinder 11 and a sealing cap 12. The cylinder 11 is used to insert into the borehole. The sealing cap 12 is disposed at the top of the cylinder 11 and is used to seal the borehole.

[0029] In this embodiment, after drilling is completed, the foundation borehole sealing device 1 can be installed in the borehole as a temporary protective device to protect it. Specifically, the cylinder 11 is inserted into the borehole, and the cylinder 11 can support the inner wall of the borehole to prevent the internal structure of the borehole from collapsing and being damaged. A sealing cap 12 is provided at the top of the cylinder 11 corresponding to the opening of the borehole. The sealing cap 12 can seal the borehole to prevent external debris from entering the borehole and thus blocking it.

[0030] As can be seen from the above, the foundation borehole sealing device 1 of this utility model supports the borehole and maintains its shape by inserting the cylinder 11 into the borehole, and seals the borehole opening with the sealing cap 12 at the top of the cylinder 11 to prevent external debris from clogging the borehole. This not only prevents the borehole itself from collapsing due to loose soil, but also prevents the borehole from being blocked by environmental factors. It effectively solves the problem in the prior art that boreholes are easily affected by human or natural factors, causing collapse and blockage, which affects inspection and acceptance.

[0031] Specifically, in some embodiments, such as Figure 1As shown, a cavity is formed inside the cylinder 11. A first opening is provided at the top of the cylinder 11, and a second opening is provided at the bottom of the cylinder 11. The first and second openings communicate with the cavity, respectively. The sealing cover 12 includes a cover plate 121 and a movable cover 122. The cover plate 121 is connected to the cylinder 11 and has a through hole that communicates with the first opening. The movable cover 122 is movably disposed in the through hole for closing or opening the through hole.

[0032] In this embodiment, a cavity is formed inside the cylinder 11. The cavity is a through cavity, with its top connected to the first opening and its bottom connected to the second opening. The cylinder 11 is connected to a cover plate 121, which is used to connect to the ground around the borehole. A through hole on the cover plate 121 is connected to the first opening. When the movable cover 122 closes the through hole, the movable cover 122 and the cover plate 121 can jointly seal the entire borehole, preventing external debris from entering and clogging it. After the borehole passes inspection, the movable cover 122 can be controlled to open the through hole, allowing the through hole and the cavity to form a filling channel leading to the interior of the borehole. Coarse sand is then backfilled and compacted into the borehole through this filling channel. After backfilling is completed, the foundation borehole sealing device 1 can be removed from the borehole for subsequent reuse.

[0033] Specifically, in some embodiments, the movable cover 122 and the cover plate 121 are rotatably connected, and the movable cover 122 can be flipped relative to the cover plate 121 to close or open the through hole.

[0034] In this embodiment, by rotatably mounting the movable cover 122 on the cover plate 121 (for example, by hinged the movable cover 122 and the cover plate 121 together), the movable cover 122 can be flipped on the cover plate 121 to cover the opening of the through hole, or to open the through hole. The structure is simple, convenient and practical.

[0035] Specifically, in some embodiments, such as Figure 1 As shown, a pull ring 123 is provided on the side of the movable cover 122 opposite to the through hole.

[0036] In this embodiment, by providing a pull ring 123 on the side of the movable cover 122 away from the through hole, relevant personnel can adjust the position of the movable cover 122 through the pull ring 123 to close or open the through hole. The structure is simple and the operation is convenient.

[0037] Specifically, in some embodiments, the pull ring 123 can be designed to be concealed. Specifically, the upper side of the movable cover 122 can be configured to form a receiving groove, in which the pull ring 123 is disposed. The pull ring 123 can rotate relative to the receiving groove to extend out of the receiving groove or be completely retracted into the receiving groove.

[0038] Specifically, in some embodiments, the projection of the cylinder 11 onto the plane of the cover plate 121 is located within the cover plate 121.

[0039] In this embodiment, the projection of the cylinder 11 onto the plane of the cover plate 121 is located within the cover plate 121, which means that the cover plate 121 extends outward from the cylinder 11, so that the cover plate 121 can be pressed onto the ground around the probe hole to fix the position of the cover plate 121 and the cylinder 11.

[0040] In one specific embodiment, such as Figure 1 As shown, the cover plate 121 is a circular plate with a circular through hole at the center. The cylinder 11 is a cylindrical tube and the cylinder 11 and the cover plate 121 are coaxially arranged.

[0041] In some embodiments, the cylinder 11 and the cover plate 121 are detachably connected. In this embodiment, by detachably connecting the cylinder 11 and the cover plate 121, construction personnel can disassemble and assemble the cylinder 11 and the cover plate 121 as needed, making it convenient to carry and transport.

[0042] Specifically, in some embodiments, the outer peripheral surface of the cylinder 11 is formed with a first thread, and the inner wall of the through hole is formed with a second thread that matches the first thread. The cylinder 11 and the cover plate 121 are connected by the first thread and the second thread.

[0043] In this embodiment, by providing a first thread and a second thread on the cylinder 11 and the cover plate 121 respectively, the first thread and the second thread can cooperate with each other to enable threaded connection between the cylinder 11 and the cover plate 121. The structure is simple and convenient for construction personnel to disassemble and assemble.

[0044] In some embodiments, the cylinder 11 includes a plurality of sub-cylinders, which are detachably connected in sequence.

[0045] In this embodiment, multiple sub-cylinders are connected in sequence to assemble a cylinder 11, allowing construction personnel to adjust the number of sub-cylinders according to the depth of the probe hole and the looseness of the nearby soil layer, thereby adjusting the length of the entire cylinder 11, so that the cylinder 11 can be used for probe holes of different depths and soil structures.

[0046] In some embodiments, such as Figure 1 As shown, the top of the sealing cap 12 is provided with a coding area 124, which is used to set the identification of the probe hole.

[0047] In this embodiment, a coding area 124 is reserved on the top of the sealing cover 12. The coding area 124 can be used to set markers corresponding to the probe holes. Specifically, the markers can be coding marks pasted on the coding area 124, or they can be steel stamps with relevant numbers, which facilitates the construction personnel to record the corresponding probe holes.

[0048] Alternatively, in some embodiments, such as Figure 1 As shown, the cylinder 11 and / or the sealing cap 12 are made of ABS plastic (Acrylonitrile Butadiene Styrene plastic). ABS plastic parts have good impact resistance and toughness, good corrosion resistance and surface hardness, are easy to process, and are low in cost.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
