Description

Technical Field

[0001] The utility model relates to the technical field of detecting the hole forming of secant piles, in particular to a device for detecting the verticality of the hole forming of secant piles. Background Technique

[0002] The hole forming method of secant piles is a commonly used foundation treatment method, which is applicable to areas with soft soil layers, high humidity and low strength. By using secant pile equipment, the pile heads are bitten into the soil layer to form a stable hole for engineering such as soil improvement or foundation support.

[0003] At present, during the construction of the hole forming of secant piles in the construction process, verticality detection is often required. Usually, a temporarily built measuring device is used in cooperation with a plumb bob or an electronic inclinometer for detection. Because there are many pile holes in general construction sites and the hole diameters of different pile holes are different, it is necessary to make detection rings with different diameters to correspond to the diameters of the pile holes, resulting in overly cumbersome preparation before detection and lack of convenience.

[0004] Therefore, it is particularly important to design a device for detecting the verticality of the hole forming of secant piles to change the above technical defects and improve the overall practicability. Content of the Utility Model

[0024] Embodiment, please refer to Figures 1-3 The present utility model provides a technical solution:

[0025] A device for detecting the verticality of the hole formed by a secant pile, comprising a fixed base 1. On one side of the top of the fixed base 1, there is a support frame 2. At the rear of the support frame 2, there is a rotating motor 3. The output end of the rotating motor 3 extends into the interior of the support frame 2 and is fixedly connected with a driving pulley 4 through a shaft rod. On the other side of the top of the fixed base 1, there is a winding drum 5 rotatably connected. On the outer side of the winding drum 5, there is a driven pulley 6. A transmission belt 7 is connected between the driving pulley 4 and the driven pulley 6. A steel wire suspension rope 8 is wound and retracted on the outer side of the winding drum 5. The bottom end of the steel wire suspension rope 8 is connected with an adjustable detection mechanism 9;

[0026] Both ends of the winding drum 5 are rotatably connected through rotating brackets, and the rotating brackets are fixedly connected to the top of the fixed base 1 by bolts.

[0027] In this embodiment, please refer to Figure 3 , the adjustable detection mechanism 9 includes a four-corner bracket 901. Rectangular grooves 902 are opened at the four corners inside the four-corner bracket 901. At the middle position of the top of the four-corner bracket 901, there is a lifting seat 903. At the central position of the bottom of the four-corner bracket 901, there is a plumb line 904 connected. At the bottom end of the plumb line 904, there is an electronic inclinometer 905. Inner grooves 906 are symmetrically opened at the four corners of the top of the four-corner bracket 901 corresponding to the positions of the rectangular grooves 902. A support plate 907 is fixed inside the inner groove 906. A gear 908 is rotatably connected between two groups of support plates 907 at the same corner. The shaft rod of the gear 908 penetrates through one end of the support plate 907 and is connected with a forward and reverse motor 909. A rack 910 meshing with the gear 908 is slidably connected inside the rectangular groove 902. The outer end of the rack 910 is fixed with a concave frame 911. A guide wheel 912 is rotatably connected inside the concave frame 911. A scale line 913 is arranged on the side wall of the rack 910;

[0028] A controller is arranged on the outer side of the fixed base 1. The controller is respectively connected with the rotating motor 3, the electronic inclinometer 905, and the forward and reverse motor 909 through wires, and the connection method is electrical connection. The bottom end of the steel wire suspension rope 8 is fixedly connected to the top position of the lifting seat 903. The forward and reverse motor 909 is fixedly installed on the corresponding support plate 907 by bolts. Convex strips are arranged on both the left and right sides of the rack 910. Sliding grooves matched with the convex strips are opened on both the left and right sides inside the rectangular groove 902, so that the rack 910 can stably extend and retract. Grooves for the extension and retraction of the rack 910 are opened at the four top corners of the four-corner bracket 901, facilitating the extension of the rack 910.

[0029] The working process of the utility model is as follows: When in use, the four-corner bracket 901 is adjusted according to the aperture sizes of different pile holes. By adjusting multiple forward and reverse motors 909 to drive the rotation of the gear 908, the rack 910 at the bottom meshes and cooperates to make an extending or retracting action. With the cooperation of the scale line 913, the center point of the four-corner bracket 901 can be kept at the position of the central axis of the pile hole, so as to facilitate the cooperation with different aperture sizes of the pile hole. Then, the four-corner bracket 901 is placed into the drill hole. Wait for the plumb line 904 and the electronic inclinometer 905 to be stable. Then, under the transmission cooperation of the driving pulley 4, the driven pulley 6 and the transmission belt 7, the rotating motor 3 is used to drive the winding drum 5 to rotate, so that the wire suspension rope 8 drives the four-corner bracket 901 to slowly move down, thereby detecting the verticality of the pile hole. The adjustable detection mechanism of this device can, on the premise of keeping it at the position of the central axis of the pile hole, facilitate the verticality detection of pile holes with different aperture sizes and can maintain the overall stability, so as to improve the convenience during the verticality detection of the formed hole of the secant pile, and thus facilitate the detection of pile holes with different diameters.
