Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation detection, in particular to a pile foundation detection device for construction engineering. Background Art

[0002] Building pipe piles are the foundation of the building structure, which directly affects the stability of the building. In order to ensure that the building maintains good stability during subsequent use, the pipe piles must be tested for strain force after the construction of the building pipe piles is completed; the main function of the low-strain reflection wave method is to test the integrity of the pile body structure, such as determining the location of pile body defects, calibrating the construction pile length, and qualitatively estimating the concrete strength grade. At present, it is widely used in building construction. The specific operation of the low-strain reflection wave method is to connect a low-strain detection terminal through a wire through a waveform collector, press the lower end of the low-strain detection terminal on the pile head, and then use a rubber hammer to continuously hit the pile head at a position 90° between the pile head and the low-strain detection terminal, so that the low-strain detection terminal collects a sufficient number of sound wave reflection waves;

[0003] According to the Chinese patent announcement number: CN218027874U, a low-strain detection device for pile foundations used in construction engineering is disclosed. By casting a fixed plate on the top of the pile pipe, the low-strain detection end can be easily inserted into the detection hole by pulling out the plug, thereby improving the fitting stability between the pile foundation and the pile foundation, thereby greatly improving the detection accuracy;

[0004] In this technical solution, the detection hole is protected by plugging the detection hole with a plug. During use, people may forget to insert the plug into the detection hole or the plug may be lost, resulting in failure to plug the detection hole in time, thereby affecting the protection effect of the detection hole. For this reason, we propose a pile foundation detection device for construction engineering. Utility Model Content

[0005] The purpose of the utility model is to provide a pile foundation detection device for construction engineering, which solves the problems in the background technology.

[0007] The protection mechanism includes a fixed shaft and a baffle plate. The fixed shaft is fixedly installed on the top of the fixed plate. The baffle plate is provided with an axial hole. The baffle plate is movably sleeved on the outer wall of the fixed shaft through the axial hole. A torsion spring is fixedly connected between the inner wall of the axial hole and the outer wall of the fixed shaft. A sealing gasket is fixedly installed on the bottom end of the baffle plate, and the sealing gasket is in close contact with the top surface of the fixed plate.

[0008] Preferably, a protective sleeve is provided on the top of the fixed shaft, and the protective sleeve is fixedly installed on the top of the baffle. By providing the protective sleeve, a certain protective effect can be played on the torsion spring, thereby increasing the service life of the torsion spring.

[0009] Preferably, a handle is fixedly mounted on the top of the baffle plate. By providing the handle, it is convenient for personnel to rotate the baffle plate through the handle, thereby facilitating operation.

[0010] Preferably, the number of the steel bar perforations is several, and the number of the detection holes is four.

[0013] The utility model provides a pile foundation detection device for construction engineering. The pile foundation detection device for construction engineering has the following beneficial effects:

[0014] (1) The pile foundation detection device for construction engineering is provided with a protective mechanism. After the low-strain detection end head has completed the detection, the baffle can automatically and timely protect the detection hole to prevent the residue dropped during the construction from falling into the detection hole. This solves the problem that in the prior art solution, the detection hole is protected by plugging the detection hole with a plug. During use, there is a possibility that a person may forget to plug the plug into the detection hole or the plug may be lost, resulting in the inability to plug the detection hole in time, thereby affecting the protection effect of the detection hole.

[0015] (2) The pile foundation detection device for construction engineering can reduce the friction between the low-strain detection terminal and the baffle when the low-strain detection terminal is inserted into the detection hole by setting a roller and a rotating shaft, thereby improving the flexibility of the low-strain detection terminal when it is inserted into or pulled out of the detection hole, which is convenient for personnel to operate, has a simple structure and is highly practical.

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] In the description of the present invention, unless otherwise specified, "multiple" means two or more; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Embodiment 1:

[0024] The pile foundation detection device for construction engineering provided by the utility model is preferably implemented as follows Figures 1 to 4 As shown: A pile foundation detection device for construction engineering includes a fixing plate 1, a steel bar through hole 2 is opened on the fixing plate 1, a detection hole 3 is arranged inside the steel bar through hole 2, the detection hole 3 is opened on the fixing plate 1, and a protective mechanism 4 is arranged above the detection hole 3;

[0025] The protection mechanism 4 includes a fixed shaft 401 and a baffle 402. The fixed shaft 401 is fixedly installed on the top of the fixed plate 1. The baffle 402 is provided with an axial hole 403. The baffle 402 is movably sleeved on the outer wall of the fixed shaft 401 through the axial hole 403. A torsion spring 404 is fixedly connected between the inner wall of the axial hole 403 and the outer wall of the fixed shaft 401. A sealing gasket 405 is fixedly installed at the bottom end of the baffle 402, and the sealing gasket 405 is in close contact with the top surface of the fixed plate 1.

[0026] Specifically, in the above technical solution, when the pile foundation detection device for construction engineering is in use, when the low-strain detection terminal needs to be inserted into the detection hole 3, the baffle plate 402 can be pulled by the handle 5 to rotate the baffle plate 402, so that the baffle plate 402 twists the torsion spring 404, so that the baffle plate 402 drives the sealing gasket 405 to move away from above the detection hole 3, completely exposing the detection hole 3, and then the low-strain detection terminal can be inserted into the detection hole 3 for detection; when the detection is completed, the low-strain detection terminal is directly pulled out upwards, and when the low-strain detection terminal is completely pulled out, the baffle plate 402 will be reset under the reset force of the torsion spring 404. The baffle plate 402 is rotated to reset, so that the baffle plate 402 drives the sealing gasket 405 to cover the detection hole 3 again, and the detection hole 3 is protected again. Through this mechanism, after the detection of the low-strain detection end is completed, the baffle plate can automatically and timely protect the detection hole 3 to prevent residues dropped during construction from falling into the detection hole 3, which solves the problem that in the prior art solution, the detection hole 3 is protected by plugging the detection hole 3 with a plug. During use, people may forget to insert the plug into the detection hole 3 or the plug is lost, resulting in the inability to timely plug the detection hole 3, thereby affecting the protection effect of the detection hole 3.

[0028] The protective cover 406 can provide a certain degree of protection for the torsion spring 404 and improve the service life of the torsion spring 404 .

[0029] Furthermore, a handle 5 is fixedly mounted on the top of the baffle 402;

[0030] Wherein, by providing the handle 5, it is convenient for personnel to rotate the baffle plate 402 through the handle 5, thereby facilitating the operation of the personnel.

[0033] Specifically, in the above technical solution, by setting a rotating roller 7 and a rotating shaft 8, the friction between the low-strain detection terminal and the baffle 402 can be reduced when the low-strain detection terminal is inserted into the detection hole 3, thereby improving the flexibility of the low-strain detection terminal when it is inserted into or pulled out of the detection hole 3, which is convenient for personnel to operate, has a simple structure, and is highly practical.

[0034] Furthermore, the number of the grooves 6 and the number of the rollers 7 on the baffle plate 402 are both two.
