[0031] The positioning device 100 and the sampling device having the same according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0032] like Figure 1 and Figure 2 As shown, the positioning device 100 according to the embodiment of the first aspect of the utility model includes a base 10, a positioning member 20 and an auxiliary member 30. The positioning member 20 is adjustably connected to the base 10 along a first plane. The positioning member 20 has a first through hole 20a. The axis of the first through hole 20a is perpendicular to the first plane. The auxiliary member 30 is detachably installed in the first through hole 20a. The auxiliary member 30 has a mounting portion 30a. On the first plane, the center of the first through hole 20a coincides with the center of the mounting portion 30a.

[0033] Specifically, Figure 1 and Figure 2As shown, the positioning device 100 in the embodiment of the utility model includes a base 10, and the base 10 is used to provide support. The positioning member 20 is adjustably connected to the base 10 along the first plane, so that the positioning member 20 can be adjusted relative to the base 10 along the first plane. The positioning member 20 has a first through hole 20a, the axis of the first through hole 20a is perpendicular to the first plane, and the first through hole 20a can be used to place the drill rod of the rotary grouting equipment to form a reinforcement pile. The auxiliary member 30 is detachably mounted on the first through hole 20a, which is convenient for installation and disassembly. The auxiliary member 30 has a mounting portion 30a, and the mounting portion 30a can be used to install a layout rod so that the layout position can be determined by the layout rod, and the detachable connection between the auxiliary member 30 and the first through hole 20a is convenient for removing the auxiliary member 30 and placing the drill rod in the first through hole 20a after the layout rod determines the layout position. On the first plane, the center of the first through hole 20a coincides with the center of the mounting portion 30a, so that the centers of the sampling rod and the drill rod can coincide, making it easier to determine the center of the drill rod through the sampling rod, with higher stability and accuracy.

[0034] Therefore, if Figure 1 and Figure 2 As shown, according to the positioning device 100 of the utility model, by providing a positioning member 20 that is adjustably connected to the base 10, it is convenient to adjust the position of the positioning member 20, and by setting the center of the first through hole 20a and the center of the mounting portion 30a to coincide, so that the center of the reinforcement pile can be determined by the auxiliary member 30, the subsequent drill rod placement is convenient, and the stability and accuracy are high.

[0035] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the positioning member 20 is connected to the base 10 through at least one adjustment component 40, and the adjustment component 40 includes an adjustment rod 41, which is adjustably connected between the positioning member 20 and the base 10 along a first direction, and the adjustment rod 41 is movably connected to the base 10 along a second direction that forms a certain angle with the first direction.

[0036] The positioning member 20 is connected to the base 10 via at least one adjusting component 40 . Specifically, the positioning member 20 is connected to the base 10 via one or more than two adjusting components 40 .

[0037] The adjustment assembly 40 includes an adjustment rod 41, which is adjustably connected between the positioning member 20 and the base 10 along a first direction, so that the positioning member 20 can be adjusted relative to the base 10 along the first direction. For example, the positioning member 20 can move in a direction away from the base 10 along the first direction, or move in a direction close to the base 10 along the first direction.

[0038] The adjusting rod 41 is movably connected to the base 10 along a second direction that forms a certain angle with the first direction, so that the adjusting rod 41 can drive the positioning member 20 to move along the second direction.

[0039] In some embodiments, there may be one or more bases 10. When there is one base 10 and the base 10 can be arranged in a certain direction of the positioning member 20, an adjustment component 40 can be arranged between the base 10 and the positioning member 20; when there is one base 10 and the positioning member 20 is located in the base 10, there may be one or more adjustment components 40. When there is one adjustment component 40, it can be arranged between the base 10 and the positioning member 20 along a certain direction. When there are multiple adjustment components 40, multiple adjustment components 40 can be arranged at intervals along the circumference of the positioning member 20. Preferably, there is one base 10 and the positioning member 20 is located in the base 10, and multiple adjustment components 40 are evenly spaced and distributed around the circumference of the positioning member 20. When there are multiple bases 10, multiple bases 10 can be arranged at intervals along the circumference of the positioning member 20, and one adjustment component 40 can be arranged between each base 10 and the positioning member 20.

[0040] The first direction and the second direction form a certain angle, so that the adjustment rod 41 can be adjusted in two directions, thereby increasing the adjustment range of the adjustment rod 41. It is understandable that the first direction and the second direction can form an acute angle, a right angle, or an obtuse angle. In the present application, the first direction and the second direction form a right angle, which is convenient for adjusting the position.

[0041] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the adjustment component 40 also includes an adjustment member 42, the base 10 is provided with a through hole 10a, one end of the adjustment rod 41 is axially positioned with the positioning member 20, and the other end is passed through the through hole 10a and is threadedly connected with the adjustment member 42, and the adjustment member 42 abuts against the outside of the through hole 10a.

[0042] One end of the adjusting rod 41 is axially positioned with the positioning member 20, so that the adjusting rod 41 can drive the positioning member 20 to move in the axial direction. Specifically, one end of the adjusting rod 41 can be fixedly connected to the positioning member 20, such as by welding, etc.; it can also be snap-connected; it can also be rotatably connected, etc. In the present application, one end of the adjusting rod 41 is welded to the positioning member 20, and the adjusting rod 41 is provided with a plurality of reinforcing ribs 21 on both sides of the axial direction.

[0043] The other end of the adjusting rod 41 is passed through the through hole 10a and is threadedly connected to the adjusting member 42. In this way, the relative position of the adjusting rod 41 and the adjusting member 42 can be changed by spirally rotating the adjusting member 42 and the adjusting rod 41. The adjusting member 42 abuts against the outside of the through hole 10a. In this way, the position of the adjusting member 42 relative to the base 10 remains unchanged. The change in the relative position of the adjusting rod 41 and the adjusting member 42 is the change in the position of the adjusting rod 41 relative to the base 10, thereby changing the position of the positioning member 20 relative to the base 10.

[0044] In some embodiments, the adjusting member 42 can be arranged outside the via hole 10a close to the positioning member 20 or outside the positioning member 20. In the present application, the adjusting member 42 is arranged outside the via hole 10a away from the positioning member 20 for easy adjustment. The adjusting member 42 can be positioned outside the via hole 10a by a positioning structure. In the present application, there are multiple adjusting members 42, and two adjusting members 42 are arranged opposite to each other along the first direction and the second direction.

[0045] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the via hole 10a is a long hole extending along the second direction.

[0046] The through hole 10 a is configured as a long hole extending along the second direction, so that the adjusting rod 41 can move along the long hole to achieve a movable connection with the base 10 in the second direction.

[0047] Of course, the present application is not limited thereto, and in other embodiments, the adjustment rod 41 may also be movably connected to the base 10 along the second direction through a structure.

[0048] In some embodiments of the present invention, Figure 1 As shown, the mounting portion 30a is a second through hole, and the axis of the second through hole is perpendicular to the first plane.

[0049] The mounting portion 30 a is set as a second through hole, and the axis of the second through hole is perpendicular to the first plane, so that the lofting rod can be inserted into the mounting portion 30 a, which facilitates the assembly of the lofting rod and the auxiliary component 30 .

[0050] Of course, it is understandable that the mounting portion 30a may also be other structures as long as the lofting rod can be installed. For example, the mounting portion 30a may be a cylindrical structure, and the axis of the cylindrical structure is perpendicular to the first plane, and the lofting rod can be inserted into the cylindrical structure.

[0051] In some embodiments of the present invention, Figure 1 As shown, the outer periphery of the auxiliary member 30 matches with the first through hole 20 a , and the auxiliary member 30 is provided with at least one limiting member 31 , which overlaps the upper surface of the positioning member 20 .

[0052] The outer periphery of the auxiliary member 30 matches with the first through hole 20a, so that the auxiliary member 30 will not move in the radial direction of the first through hole 20a, and has high stability. The auxiliary member 30 is provided with at least one stopper 31, and the stopper 31 overlaps the upper surface of the positioning member 20, so that the auxiliary member 30 will not fall from the first through hole 20a and can be limitedly matched with the first through hole 20a.

[0053] There may be one or more than two limiting members 31, and the limiting members 31 may be arranged at any position of the auxiliary member 30, for example, they may be arranged in the circumferential direction of the auxiliary member 30 or within the circumferential direction of the auxiliary member 30; the limiting members 31 may be arranged on the upper surface of the auxiliary member 30, or may be arranged at the circumferential edge of the limiting members 31. In the present application, the limiting members 31 are limiting protrusions arranged at the circumferential edge of the auxiliary member 30, and the first through hole 20a is provided with limiting grooves matched with the limiting protrusions.

[0054] In some embodiments of the present invention, Figure 1 As shown, the first through hole 20a is a stepped hole at one side close to the upper surface of the positioning member 20, and the auxiliary member 30 is overlapped in the stepped hole.

[0055] The auxiliary component 30 is overlapped in the stepped hole, so that the auxiliary component 30 cannot move in the radial direction of the first through hole 20a, will not fall off in the axial direction, and is convenient for installation and disassembly.

[0056] The depth of the step hole may be the same as or different from the thickness of the auxiliary member 30 . For example, the depth of the step hole may be greater than or less than the thickness of the auxiliary member 30 .

[0057] like Figure 4 As shown, the layout device 1000 according to the embodiment of the second aspect of the utility model includes a steel casing 200 and the positioning device 100 in the above embodiment, the axis of the first through hole 20a is parallel to the axis of the steel casing 200, and the axis of the first through hole 20a is located in the steel casing 200, and the base 10 and the steel casing 200 are detachably installed.

[0058] According to the layout device 1000 of the utility model, by adopting the positioning device 100 in the above embodiment, the position where the drill rod is to be lowered into the steel casing 200 can be positioned, with high stability and accuracy, ensuring the construction requirements.

[0059] In some embodiments, the steel casing 200 is a cylindrical tube, and the base 10 of the positioning device 100 is a rectangular frame. Furthermore, the base 10 can be formed by processing channel steel.

[0060] It should be noted that, through the positioning device 100 in the above embodiment, the deviation of the reinforcement pile in the plane is not more than 5 cm. This is conducive to the reinforcement piles in the steel casing 200 to form full-section bite piles at the bottom of the foundation pit, thereby achieving the water-sealing effect of the reinforcement surface.

[0061] In some embodiments of the present invention, Figure 5 As shown, the base 10 is connected to the steel casing 200 through at least one detachable component 300, and the detachable component 300 includes a fixing plate 301 fixedly connected to the base 10, and a screw 302 threadedly connected to the fixing plate 301, and one end of the screw 302 abuts against the side wall of the steel casing 200 to install the base 10 and the steel casing 200.

[0062] There can be one or more detachable components 300. When there is one detachable component 300, a limiting portion can be set at a position on the base 10 opposite to the detachable component 300. When there are more than two detachable components 300, they can be set along the circumference of the base 10. In this way, one end of the screw 302 abuts against the side wall of the steel casing 200, and the steel casing 200 can be restricted between the limiting portion and the detachable component 300 or multiple detachable components 300, so as to install the base 10 and the steel casing 200.

[0063] In some embodiments, reinforcing plates 304 are provided at both ends of the fixing plate 301 .

[0064] In some embodiments of the present invention, Figure 5 As shown, the detachable assembly 300 further includes a foot support 303 , which is connected to one end of the screw rod 302 , and the contact area between the foot support 303 and the steel casing 200 is larger than the contact area between the foot support 303 and the screw rod 302 .

[0065] By providing the foot support 303 whose contact area with the steel casing 200 is larger than that with the screw 302, the pressure on the steel casing 200 is reduced, and it is not easy to press an indentation or damage on the steel casing 200, thereby protecting the steel casing 200. Specifically, the foot support 303 can be in the shape of a plate, one side of which is connected to the screw 302, and the other side is pressed against the steel casing 200.
