[0004] Currently, when constructing cast-in-place piles, the borehole is first relocated, then the hole is cleaned, and finally the reinforcing cage is lowered for concrete pouring. After placement, the reinforcing cage is easily tilted by external forces, or it may not be placed vertically and is directly poured into the concrete, which will affect the load-bearing capacity of the subsequent cast-in-place pile. Currently, cast-in-place piles cannot detect the placement of the reinforcing cage. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1-8 The present invention provides the following technical solution: a micro-hole grouting pile for photovoltaic construction, comprising a concrete pile body 1 and a steel cage 2, wherein the steel cage 2 is disposed inside the concrete pile body 1;

[0037] Example 1: This example provides the following technical solution, disclosing that a positioning rod 3 is provided on the inner side of the reinforcing cage 2, and an extension rod 4 is installed above the positioning rod 3. The upper end of the extension rod 4 penetrates the upper surface of the concrete pile 1. A positioning plate 5 is fixed on the inner side of the reinforcing cage 2. The positioning plate 5 is set on the outer side of the extension rod 4 and the positioning rod 3 to provide a positioning effect. A connecting seat 8 is connected above the extension rod 4, and an installation groove 9 is opened above the connecting seat 8 for connecting photovoltaic equipment. An installation seat 12 is provided above the connecting seat 8, and an tilt detection mechanism is provided above the installation seat 12 to detect the placement direction of the reinforcing cage 2. A piercing head 7 is fixed at the lower end of the positioning rod 3, and a stop block 6 is fixed above the piercing head 7. The diameter of the stop block 6 is larger than the diameter of the positioning rod 3.

[0038] During construction, the hole is first drilled using a drilling rig. After cleaning the hole, the reinforcing cage 2 is lowered. Before lowering the reinforcing cage 2, the extension rod 4 and positioning rod 3 are installed, and the positioning plate 5 is used to position it. After installation, the piercing head 7 is inserted into the bottom of the hole to position the reinforcing cage 2. Then, the placement direction of the reinforcing cage 2 is detected by the tilt detection mechanism. After adjustment, concrete can be poured. After pouring, the mounting base 12 is removed from the connecting base 8 and can be reused.

[0039] Example 2: Based on Example 1, a connector 10 is fixed to the lower end of the connecting seat 8 and the lower end of the extension rod 4. A connecting groove 11 is provided at the upper end of the positioning rod 3 and the upper end of the extension rod 4. The connecting groove 11 and the connector 10 form a threaded connection. A clamping mechanism is provided below the mounting seat 12 to clamp the mounting seat 12 at the upper end of the connecting seat 8 and to block the opening of the mounting groove 9. The clamping mechanism includes a clamping block 17, a slider 18 and a return spring 19. The clamping blocks 17 are evenly distributed below the mounting seat 12 and have an inclined structure design below them. The slider 18 is fixed to the upper end of the clamping block 17 and is located inside the mounting seat 12, forming a horizontal sliding structure between the slider 18 and the mounting seat 12. The return spring 19 is provided outside the slider 18 to provide thrust to the slider 18.

[0040] The extension rod 4 can be spliced ​​together through the threaded connection between the connector 10 and the connecting groove 11, so as to adapt to the use of steel cages 2 of different heights. The mounting base 12 is clamped on the outside of the connecting base 8 by the clamping block 17. The mounting base 12 can be directly pulled up and removed later. During installation, the mounting base 12 is directly pressed down. The inclined surface of the clamping block 17 can slide along the connecting base 8, so that the clamping block 17 can move smoothly to the outside of the connecting base 8.

[0041] Example 3: Based on Example 1, a tilt detection mechanism is disclosed, including a marker post 15, an outer cover 16, and a vertical correction mechanism. The marker post 15 is positioned above the mounting base 12. The outer cover 16 is positioned outside the marker post 15, and the upper part of the outer cover 16 has an open structure design. The vertical correction mechanism is positioned below the marker post 15 to correct the marker post 15 in the vertical direction. The vertical correction mechanism includes a movable ball 13 and a counterweight 14. The movable ball 13 is fixed to the lower end of the marker post 15, and the movable ball 13 and the mounting base 12 form a rotatable connection. The counterweight 14 is fixed to the lower end of the movable ball 13 to provide a downward pulling force to the movable ball 13.

[0042] When the reinforcing cage 2 tilts, the counterweight 14 provides a downward force to the movable ball 13, causing the movable ball 13 to move. This causes the movable ball 13 to move the marker post 16. The marker post 16 moves at the opening of the outer cover 16 and comes into contact with the outer cover 16, indicating that the reinforcing cage 2 is tilted at this time. This facilitates timely adjustment of the reinforcing cage 2 and improves the subsequent pile formation quality.

[0044] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
