The key to its construction lies in the efficient and accurate layout of pile points. Generally, the bare soil compaction piles are densely spaced, the pile diameter is small, and the pile positions are arranged in a plum blossom shape. The traditional pile point positioning method usually uses total stations, RTK and other measuring instruments to measure the pile points one by one, and then mark and locate them on the ground corresponding to the pile points. This method is cumbersome to operate, has low operating efficiency, and is difficult to control the accuracy of laying out lines. At the same time, the positioning marks are easily offset and damaged by construction disturbances, resulting in the need for re-measurement and positioning, which seriously affects the construction efficiency.

[0038] The embodiments of the present invention are described below with reference to the accompanying drawings.

[0039] The present invention provides a dense pile point positioning device, which is used to locate densely arranged pile body points in foundation treatment construction, and can quickly and efficiently complete the layout of the pile points, reduce the operation difficulty, and improve the construction efficiency.

[0040] like Figure 1-Figure 3 As shown, a dense pile point positioning device includes a positioning component 1, a drilling component 2 and a lime filling component 3, wherein the positioning component 1 is used to locate the proposed construction position of the pile body; it includes a plurality of positioning rings 11, and the relative positions between the positioning rings 11 are the same as the relative positions between the pile bodies; the drilling component 2 is used to drill holes in the middle of the positioning rings 11 to form positioning holes; the lime filling component 3 is used to fill white lime into the positioning holes, and the pile body point 4 to be constructed can be easily identified through the white lime, so as to facilitate the subsequent construction of the pile body with the position of the white lime as the center.

[0041] It can be understood that the distance between the densely arranged pile bodies is small, and the pile bodies are arranged according to certain rules. The positioning ring 11 in the positioning assembly 1 in the present application matches the relative position of the pile body; by reasonably arranging the positioning rings 11, each positioning ring 11 is accurately aligned with the corresponding pile body, thereby ensuring that each positioning ring 11 can accurately locate the position of a pile body; and then by determining the position and angle of a positioning ring 11, the positioning of the pile body positions corresponding to all the positioning rings 11 in the positioning assembly 1 can be completed at one time, which greatly improves the efficiency and accuracy of pile point positioning.

[0042] Furthermore, the positioning assembly 1 includes at least two rows of positioning rings 11, and the positioning rings 11 are connected by connecting rods 12. Usually, the pile bodies are arranged in rows. In the present application, two rows of positioning rings 11 are arranged, and the spacing between the positioning rings 11 is set according to the design, so that the positioning rings 11 can accurately position the two rows of pile bodies during positioning, simplifying the operation process and improving the positioning efficiency. It not only ensures that the relative position between the two rows of pile body points 4 after positioning meets the design requirements, but also further improves the positioning accuracy.

[0043] The extension line of the connecting rod 12 passes through the center of the positioning ring 11. The angle of the positioning component 1 can be accurately determined through the extension line, which is convenient for adjusting the angle of the positioning component 1. By positioning a positioning ring 11 on the positioning component 1 and then rotating the positioning component 1 according to the designed angle, the positioning of all the positioning rings 11 on the positioning component 1 can be achieved, so that each positioning ring 11 can be matched with a pile body point 4, further simplifying the operation.

[0044] Preferably, the above-mentioned connecting rods 12 form a plurality of triangular structures, so that the positioning rings 11 can be connected stably and flexibly in pairs, which not only enhances the stability of the overall structure of the positioning assembly 1, but also improves the accuracy and reliability of the connection, and is conducive to the effective combination and adjustment between multiple positioning rings 11, thereby achieving more accurate positioning and layout; at the same time, the angle of the positioning assembly 1 can be more accurately adjusted according to the extension direction of the connecting rod 12 to achieve the positioning of the pile body point 4.

[0045] The above-mentioned drilling assembly 2 includes a drill body 21 and a drill cover 22 and a drill bit 23 arranged at both ends of the drill body 21. The area of ​​the drill cover 22 is larger than the drill body 21, and the drill bit 23 is pointed; by hammering the drill cover 22, the drill body 21 can be inserted into the soil of the intended construction site, thereby forming a positioning hole. By setting the drill cover 22, it is convenient to perform the hammering operation and subsequently pull out the drilling assembly 2, and it is also easier to control the depth of the positioning hole.

[0046] Preferably, the radius of the drill body 21 is 1mm-2mm smaller than the radius of the positioning ring 11. When in use, the positioning assembly 1 is first fixed on the ground at a set position and angle, and then the drill body 21 is passed through the middle of the positioning ring 11. This helps to ensure that the center of the formed positioning hole coincides with the center of the positioning ring 11, or is within the allowable error range, without the need to re-position the position of the drill body 21.

[0047] Furthermore, the ash filling component 3 includes an ash cylinder 31 with openings at both ends and an ash filling port 32 arranged at one end of the ash cylinder 31. The ash filling port 32 is funnel-shaped. When in use, the ash cylinder 31 is inserted into the positioning hole, and then white ash is poured into the ash cylinder 31 through the ash filling port 32. The ash cylinder 31 is then removed, and the white ash can be left in the positioning hole. Because the positioning hole has a certain depth and is arranged in the vertical direction, the white ash is filled in the vertical direction. Even if the upper white ash is disturbed by construction, buried or damaged, the white ash at the bottom can still accurately mark the pile body point 4, providing a reliable basis for subsequent pile body construction.

[0048] Furthermore, in order to facilitate the insertion of the ash tube 31 into the positioning hole, the radius of the ash tube 31 is set to be smaller than the radius of the drill body 21, and the length of the ash tube 31 is not less than the length of the drill body 21, so as to facilitate the control of the amount of white ash used each time the ash is poured, so that the white ash can fill the positioning hole after the ash tube 31 is removed.

[0049] Furthermore, a handle 33 is provided on the outside of the ash tube 31 , and the distance between the handle 33 and one end of the ash tube 31 is not less than the length of the drill body 21 , so as to ensure that the ash tube 31 can penetrate into the positioning hole and facilitate the removal of the ash tube 31 .

[0050] The present application also proposes a dense pile point positioning construction method, using the dense pile point positioning device proposed in the present application, such as Figure 4 As shown, the method comprises the following steps:

[0051] S1, according to the pile point positioning diagram, survey and set the central positioning points 5 of the pile bodies at both ends of a row of pile bodies to be constructed, and form a central reference line 6, which is arranged in every other row;

[0052] Specifically, a total station and a theodolite are used to measure the positions of the centers of two pile bodies at both ends of a row of pile bodies to be constructed, that is, the positions of two center positioning points 5, and the two center positioning points 5 are connected to form a center reference line 6 by drawing a line on the ground or pulling a rope; ensure that the center reference line 6 is straight so that the center points of the row of pile bodies are all located on the center reference line 6.

[0053] In the present application, the number of interval rows of the center reference lines 6 is set according to the number of rows of positioning rings 11 on the positioning component 1; for example, in the present embodiment, two rows of positioning rings 11 are provided on the positioning component 1, which can simultaneously position two rows of pile bodies, so the center reference lines 6 are arranged in alternate rows.

[0054] S2, aligning the center of a positioning ring 11 of the positioning assembly 1 with the central positioning point 5, and aligning the centers of other positioning rings 11 arranged in the same row with the positioning ring 11 with the central reference line 6;

[0055] Specifically, one of the two central positioning points 5 located at both ends in the previous step can be selected as the positioning starting point, and the center of a positioning ring 11 located at one end on the positioning component 1 is aligned with the central positioning point 5. Whether the center of the positioning ring 11 is aligned with the central positioning point 5 can be judged based on whether the intersection of the extension line of the connecting rod 12 coincides with the central positioning point 5; after determining that the positioning ring 11 is aligned with the central positioning point 5, the positioning component 1 is rotated so that the other positioning rings 11 located in the same row as the positioning ring 11 are arranged along the pile point arrangement direction in the design, and when the connecting rod 12 between the positioning rings 11 in the row coincides with the corresponding central reference line 6 of the row, it can be determined that the positioning rings 11 on the positioning component 1 are all aligned with the corresponding pile body positions in the pile point positioning diagram, and the positioning of the corresponding pile body is completed.

[0056] S3, placing the punching assembly 2 at the center of the positioning ring 11, and hammering the punching assembly 2 to form a positioning hole;

[0057] Specifically, when placing the punching assembly 2 , the drill body 21 should be positioned at the center of the positioning ring 11 as much as possible, and the placement point of the drill body 21 can be determined based on the intersection of the extension lines of the connecting rods 12 .

[0058] S4, remove the punching component 2, and place the ash filling component 3 in the positioning hole;

[0059] S5, pouring lime into the lime cylinder 31 of the lime filling assembly 3, and then slowly removing the lime cylinder 31;

[0060] Specifically, to ensure that the amount of white ash can meet the requirement of filling the positioning hole, the height of the white ash in the ash tube 31 should be higher than the height of the ground, which can be judged based on the position of the handle 33 of the ash filling assembly 3; through this operation, the positioning of a pile body point 4 can be completed.

[0061] S6, repeating steps S3 to S5 until all the positioning rings 11 of the positioning assembly 1 are punched and filled with ash;

[0062] S7, move the positioning assembly 1 along the center reference line 6, so that the center of a positioning ring 11 of the positioning assembly 1 is aligned with the center of a positioning hole that has been filled with ash;

[0063] Specifically, the positioning component 1 moves from the central positioning point 5 at one end of the central reference line 6 to the other end. Preferably, the moving distance corresponds to the number of a row of positioning rings 11 on the positioning component 1 aligned with the central reference line 6, so that the positioning rings 11 located at one end of the row are aligned with the positions of the positioning rings 11 in the positioning component 1 in step S7 to be connected end to end, so that the position of the positioning rings 11 on the positioning component 1 after the movement corresponds to the pile body position in the pile point positioning diagram.

[0064] S8. Repeat the drilling and filling.

[0065] By repeating the above operation, the positioning of multiple rows of pile bodies arranged in a dense manner can be achieved. During construction, multiple groups of synchronous operations can be adopted to further improve the positioning efficiency of the pile bodies. Through the above technical solution, it is only necessary to measure two pile body points 4 to achieve the positioning of multiple rows of pile bodies, which simplifies the measurement and positioning operations and significantly improves the positioning efficiency.
