Description

Technical Field

[0001] The utility model relates to the field of cast-in-place pile construction, in particular to a spiral drilling machine depth display and soil cleaning device. Background Art

[0002] When drilling bored piles for new energy photovoltaic projects, the lack of a drill rod depth indicator on the auger's control panel and a scale on the drill rod makes it impossible to precisely control the hole depth. Typically, based on the bored pile hole depth indicated on the blueprint, the drill rod is painted or clearly marked at the corresponding height. This allows the drill operator to observe and control the start and stop of the drill to achieve the final hole depth. Given the large number of bored piles in photovoltaic projects, any wear and tear of the paint or the markings that fall off require repainting or re-tacking.

[0003] like Figure 1 As shown in the figure, when the drill rig is drilling, the soil or gravel drilled out is carried out of the ground by the rotating blades and continuously accumulates around the drill rod. When the drilling depth reaches the required level and the drill rod is rotated out, a conical soil pile will form around the hole, affecting the subsequent cast-in-place pile formwork work. Personnel need to be assigned to clean up the soil pile around the hole. To prevent the soil pile from being discarded into the hole and to ensure the hole depth is reached, personnel must first perform simple protection on the hole and then carefully clean up the soil pile around the hole to meet the conditions for cast-in-place pile formwork.

A second flange 121 is provided on the upper portion of the right positioning plate 120. The second flange 121 protrudes outward from the outer surface of the right positioning plate 120. The second flange 121 has an arc-shaped structure and extends from one end of the right positioning plate 120 to the other end.

[0041] The scraper 200 is arranged between the left positioning plate 110 and the right positioning plate 120, and the left positioning plate 110 and the right positioning plate 120 are fixedly connected through the scraper 200; the left positioning plate 110 and the right positioning plate 120 are detachably assembled and connected by fixing bolts 300, which is convenient for later installation and fixation.

[0042] The scraper 200 comprises:

[0043] Scraper 1 210 is fixed to one end of the left positioning plate 110. The upper end of scraper 1 210 is fixedly connected to the bottom end of flange 111. The lower end of scraper 1 210 is flush with the lower end of the left positioning plate 110. The main body of scraper 1 210 is a rectangular plate structure.

[0044] The second scraper 220 is fixed to the other end of the left positioning plate 110. The upper end of the second scraper 220 is fixedly connected to the bottom end of the flange 111. The lower end of the second scraper 220 is flush with the lower end of the left positioning plate 110. The main body of the second scraper 220 is a rectangular plate structure;

[0045] Scraper three 230 is fixed to one end of the right positioning plate 120. The upper end of scraper three 230 is fixedly connected to the bottom end of flange two 121. The lower end of scraper three 230 is flush with the lower end of the right positioning plate 120. The main body of scraper three 230 is a rectangular plate structure. Scraper one 210 and scraper three 230 are arranged correspondingly, and scraper one 210 and scraper three 230 are connected by bolts.

[0046] Scraper four 240 is fixed to the other end of the right positioning plate 120. The upper end of scraper four 240 is fixedly connected to the bottom end of flange two 121, and the lower end of scraper four 240 is flush with the lower end of the right positioning plate 120. Scraper two 220 and scraper four 240 are arranged correspondingly. The main body of scraper four 240 is a rectangular plate structure. Scraper two 220 and scraper four 240 are connected by bolts.

[0047] The fixing bolt 300 is a U-shaped bolt. The main body of the fixing bolt 300 is located between the left positioning plate 110 and the right positioning plate 120. The left positioning plate 110 is provided with a bolt hole 112, and the right positioning plate 120 is provided with a bolt hole 2 122.

[0048] The center height of bolt hole 112 is greater than the center height of bolt hole 2 122. One end of the fixing bolt 300 passes through bolt hole 112, and the other end of the fixing bolt 300 passes through bolt hole 2 122. The fixing bolt 300 is arranged obliquely in the positioning plate 100, which makes it convenient for the fixing bolt 300 to pass through the drill rod of the auger drill A, and at the same time facilitates the later fixing of the fixing bolt 300 and the drill rod of the auger drill A. The fixing bolt 300 is fixedly connected to the left positioning plate 110, the right positioning plate 120 and the drill rod of the auger drill A on the outside of the left positioning plate 110 and the right positioning plate 120 through the fixing nut 310.

[0049] Working principle of this device:

[0050] 1. Insert the fixing bolt 300 (U-shaped bolt) into the drill rod of auger drill A. Insert the ends of the fixing bolt 300 into the left positioning plate 110 and the right positioning plate 120 respectively. After the fixing bolt 300 is placed on the drill rod of auger drill A, insert the fixing nuts 310 into the ends of the fixing bolt 300 to preliminarily secure the left positioning plate 110, the right positioning plate 120 and the fixing bolt 300 (U-shaped bolt).

[0051] 2. Adjust the vertical height of the positioning plate 100 to display and control the depth of the pile. The depth of the pile is marked as h ( Figure 4 shown).

[0052] 3. Tighten the left positioning plate 110, the right positioning plate 120 and the fixing bolts 300 (U-bolts) to complete the installation of the device on the drill rod of the auger drill A.

[0053] This device is suitable for new energy photovoltaic projects. During cast-in-place pile construction, it displays the depth of the hole drilled by auger drill A and simultaneously clears soil or gravel accumulated around the hole. This device utilizes a positioning plate 100 (adjustable in height according to the hole depth) fixed to the drill rod of auger drill A to visually indicate the hole depth. Furthermore, the rotation of the drill rod during drilling drives a scraper 200 on the positioning plate 100 to rotate, clearing soil accumulated around the hole. Once the drill rod is removed, the area surrounding the hole can be cleaned, allowing for subsequent cast-in-place pile formwork.

[0054] When the positioning device scraper 200 rotates downward with the drill rod and touches the ground, the drill hole has reached the desired depth. The auger operator can visually observe this and promptly stop the rig. The scraper 200 on the positioning plate, rotating downward with the drill rod, easily clears the soil around the hole, eliminating the need for subsequent cleaning steps and reducing labor.

[0055] Since the length of the scraper 200 can be adjusted according to the diameter of the cast-in-place pile formwork, the circular ground surface formed by the scraper 200 is a perfect place to place the cast-in-place pile tubular formwork. After the formwork is adjusted, the circular mound of soil scraped by the scraper 200 is used to evenly close the gap between the formwork and the ground, preventing the possibility of grout leakage from the bottom of the formwork during pouring.
