Description

Technical Field

[0001] This utility model relates to the field of pile hole processing equipment, and in particular to a pile foundation drilling and stabilization device for building construction. Background Technology

[0002] In existing technologies, the installation of protective casings for pile holes is usually carried out after the pile construction is completed. Taking the construction of a 10-meter-deep pile hole as an example, after the pile hole is completed, a 10-meter-long protective casing is hoisted to ensure the safety of the pile hole. In certain specific cases, the installation of the protective casing may be carried out simultaneously with the pile driving process. However, when the protective casing adopts a multi-segment design, the accuracy of the docking position may be insufficient. In addition, in order to ensure a sufficiently high degree of fit between the protective casing and the inner diameter of the pile hole to guarantee its positional accuracy, the protective casing will encounter greater resistance during the burial process, thereby increasing the risk of damage or deformation to the protective casing. Moreover, burying the protective casing simultaneously during the pile driving process may cause the protective casing to fall vertically.

[0003] Furthermore, the multi-segment design of the protective casing may present other problems in practical operation. For example, the precise alignment required when connecting multiple segments of the protective casing makes the operation difficult and prone to errors. These errors not only affect the overall stability of the protective casing but may also affect the verticality and bearing capacity of the subsequent piles. During construction, inaccurate alignment of the protective casings may lead to gaps between them, allowing soil, water, or other debris to enter the pile hole, affecting the quality of the pile hole and the stability of the pile. Therefore, the construction team needs to pay extra attention to the alignment accuracy when installing the protective casings in the pile hole to ensure the quality of the entire pile foundation project.

[0029] Referring to Figures 1 to 5 , in an embodiment of the present utility model, a device for stabilizing a bored pile in building construction includes:

[0030] A base, including an annular platform and a plurality of standing feet, the plurality of standing feet being arranged circumferentially on the annular platform, and the height of the standing feet being adjustable;

[0031] A plurality of protective cylinders, arranged butt-jointed in the height direction, the protective cylinders being arranged in the middle area of the annular platform, a first step being provided on the inner wall at one end in the height direction of the protective cylinder, at least three upright "convex" - shaped empty gaps being evenly arranged in a circumferential manner on the inner wall at one end in the height direction of the protective cylinder, the empty gaps extending to the end face in the height direction, a second step being provided on the outer wall at the other end in the height direction of the protective cylinder, a plurality of fixing shafts corresponding to the empty gaps being evenly arranged in a circumferential manner on the outer wall at the other end in the height direction of the protective cylinder, a plurality of convex spiral threads being evenly arranged in a circumferential manner on the outer wall of the protective cylinder, the number of the convex spiral threads being 1 to 3 times the number of the empty gaps, the rotation angle of the convex spiral threads being between 20 and 40 degrees, and at least one through hole being provided on the circumferential wall of the protective cylinder;

[0032] At least one telescopic structure, installed on the annular platform and corresponding to the through hole;

[0033] Wherein, when the two protection cylinders are butted, the convex spiral threads on both of them are butted.

[0034] In the prior art, in order to ensure that the fit degree between the protection cylinder and the inner diameter of the pile hole is high enough to ensure the accuracy of its position, this results in a large resistance when the protection cylinder is buried, thus increasing the risk of damage or deformation of the protection cylinder.

[0035] The building construction pile foundation drilling stabilizing device provided by the utility model comprises a base, a plurality of protection cylinders and at least one telescopic structure.

[0036] The base comprises an annular platform and a plurality of standing feet. The plurality of standing feet are arranged circumferentially on the annular platform, and the standing feet support the annular platform. The height of the standing feet is adjustable, and through the adjustment of each standing foot, the horizontal support of the annular platform can be realized.

[0037] The plurality of protection cylinders are butted and arranged in the height direction. The increase of the protection cylinders can adapt to the increase of the pile driving depth. The protection cylinders are arranged in the middle area of the annular platform. A first step is arranged on the inner wall of one end of the protection cylinder in the height direction, and at least three upright "convex"-shaped empty gaps are evenly arranged in a ring on the inner wall of one end of the protection cylinder in the height direction. The empty gaps extend to the end face in the height direction. A second step is arranged on the outer wall of the other end of the protection cylinder in the height direction. A plurality of fixed shafts corresponding to the empty gaps are evenly arranged in a ring on the outer wall of the other end of the protection cylinder in the height direction.

[0038] When two protection cylinders are butted, the first step and the second step are butted to form a limiting fixation, and the fixed shaft can extend into the empty gap. Due to the "convex"-shaped arrangement of the empty gap, when the fixed shaft extends in and the adjacent protection cylinders rotate, the two can form a clamping connection, and thus a pressing or lifting action can be performed in the vertical direction. A plurality of convex spiral threads are evenly arranged in a ring on the outer wall of the protection cylinder. In the pressing and lifting actions, torsion is required so that the convex spiral threads can achieve the power of screwing in and out. The number of the convex spiral threads is 1 to 3 times the number of the empty gaps, the rotation angle of the convex spiral threads is between 20 and 40 degrees, and at least one through hole is arranged on the peripheral wall of the protection cylinder. The rotation angle of the convex spiral threads needs to be appropriate, so that when there is an appropriate screwing-in effect, there will be no large resistance. When two protection cylinders are butted, the convex spiral threads on both of them are butted.

[0039] At least one telescopic structure is installed on the annular platform. The telescopic structure corresponds to the through hole. When the protection cylinder is installed in place, through the operation of the telescopic structure, a fixation can be formed with the through hole, and at this time all the protection cylinders can be locked and fixed by the telescopic structure.

[0040] In summary, adjacent protective cylinders are connected to align their positions, thus better assisting the pile driving process. To reduce the difficulty of pressing down the protective cylinder, through the settings of the fixed shaft and the "convex"-shaped empty notch, the protective cylinder can be lifted after rotating in two directions. Convex spiral threads are provided on the outer wall of the auxiliary protective cylinder, so that the protective cylinder can produce a screwing-in effect during rotation. After the protective cylinder is in place, it forms a cooperation with the through holes on the topmost protective cylinder through the telescopic structure to achieve the fixation of the protective cylinder in the vertical direction. During use, the protective cylinders are gradually added, and they can complete the guiding and stabilizing functions throughout the pile driving process. To ensure the smooth progress of the installation process of the protective cylinder, a circumferential buckling structure on the protective cylinder and the convex spiral threads on the outer wall are introduced.

[0041] In one embodiment, the building construction pile foundation drilling and stabilizing device further includes a fixing frame connected to an external drill shaft, and the fixing frame is used to form a fixation with a plurality of the through holes on the protective cylinder.

[0042] In this embodiment, a fixing frame that can be detachably connected to the drill shaft is added. Through the combination of the fixing frame and the protective cylinder, the drill shaft can be directly utilized during the process of pressing down and lifting the protective cylinder.

[0043] In one embodiment, the convex spiral threads are welded to the protective cylinder.

[0044] In this embodiment, compared with an integral structure, defining the convex spiral threads as welded has the advantages of high structural strength and simple processing. For example, processing marks are set at the positions corresponding to the convex spiral threads on the protective cylinder, and then strip-shaped profiles are welded to the marked positions.

[0045] In one embodiment, the fixed shaft is welded to the protective cylinder.

[0046] In this embodiment, compared with an integral structure, defining the fixed shaft as welded has the advantages of high structural strength and simple processing.

[0047] In one embodiment, the standing feet are nail-shaped fixed pins, and a horizontal detection device is provided on the base.

[0048] In this embodiment, through the structural limitation of the standing feet, a pile driving and fixing effect is provided for the standing feet, providing a basis for the fixation of the base. And a horizontal detection device is provided on the base to provide an indication for the adjustment and fixation process of the standing feet.

[0049] In one embodiment, the telescopic structure is a pneumatic telescopic structure, a hydraulic telescopic structure or a threaded telescopic structure.

[0050] In this embodiment, a structural selection of the telescopic structure is proposed, and specific selection is made according to various application scenarios. For example, when the total weight of the protection cylinder is relatively large, the telescopic structure adopts a hydraulic telescopic structure; when the total weight of the protection cylinder is relatively small, the telescopic structure adopts a threaded telescopic structure.

[0051] In one embodiment, the number of the telescopic structures is multiple, and they are evenly arranged on the annular platform.

[0052] In this embodiment, if the number of the telescopic structures is increased, the telescopic structures can provide better support for the protection cylinder, providing a basis for the smooth progress of the processing process. For example, the number of the telescopic structures is two and they are arranged at an interval of 180 degrees in the circumferential direction.

[0053] In one embodiment, the number of the empty notches is six, and they are evenly arranged around the protection cylinder in the circumferential direction, and the number of the convex spiral threads is six.

[0054] In this embodiment, on the premise of not significantly increasing the processing difficulty, the bonding effect between the two protection cylinders is better. The number of the convex spiral threads is six, and on the premise of not significantly increasing the processing difficulty, the driving effect that the protection cylinder can execute is stronger.

[0055] In one embodiment, the number of the standing feet is six.

[0056] In this embodiment, a plurality of standing feet can provide a relatively stable supporting effect.

[0057] In one embodiment, the material of the protection cylinder is stainless steel.

[0058] In this embodiment, the material of the protection cylinder is restricted. Under the condition of having structural strength, its weather resistance is greatly improved.

[0059] To sum up, the building construction pile foundation drilling stability device provided by the present utility model connects two adjacent protection cylinders, makes the positions aligned, and can better assist the pile driving process. In order to reduce the difficulty of pressing down the protection cylinder, through the setting of the fixed shaft and the "convex"-shaped empty notch, the protection cylinder can be lifted after rotating in two directions; a convex spiral thread is arranged on the outer wall of the auxiliary protection cylinder, and the protection cylinder can generate a screwing-in effect during rotation; after the protection cylinder is in place, through the cooperation between the telescopic structure and the through hole on the topmost protection cylinder, the fixation of the protection cylinder in the vertical direction is realized; during the use process, the protection cylinders are gradually added, and guiding and stabilizing functions can be completed during the whole pile driving process. In order to ensure the smooth progress of the installation process of the protection cylinder, a buckling structure in the circumferential direction of the protection cylinder and a convex spiral thread on the outer wall are introduced.
