Foundation pile testing runs through the entire life cycle of the project, and the testing methods used at different times are also different. The specific testing methods include static load test, dynamic test, non-destructive testing and drilling sampling. Among them, drilling sampling is used after the foundation pile construction is completed to verify the integrity of the pile body, the condition of concrete bonding, and the thickness of sediment at the bottom of the pile.

[0003] When drilling and sampling existing engineering foundation piles, the drilling machinery is usually placed on the foundation where the pile is inserted. Due to the large size of the machinery, adjusting the drilling position is troublesome, time-consuming, and labor-intensive, which affects the efficiency of drilling and testing. Utility Model Content

[0004] To at least partially address the shortcomings of the existing technology, the main objective of this utility model is to provide a time-saving, labor-saving, and easy-to-use engineering foundation pile testing and fixing device.

[0006] According to a specific embodiment of the present invention, the locking member includes a locking screw and a nut fitted on the locking screw. One of the first half-ring and the second half-ring is provided with a locking screw, and one of the first half-ring and the second half-ring is provided with a through hole. The locking screw passes through the through hole and is locked by the nut.

[0007] Furthermore, the locking component further includes an active push-pull rod, the two ends of which are connected to the first semi-ring and the second semi-ring, respectively.

[0008] Furthermore, the active push-pull rod can be an electric push rod, a pneumatic push rod, or a hydraulic push rod.

[0010] According to a specific embodiment of the present invention, a lifting slide groove is provided on the side plate, and the horizontal plate is slidably disposed in the lifting slide groove and can move up and down under the drive of the lifting driver.

[0011] Furthermore, the end connecting the horizontal plate and the side plate is set in an "I" shape, and it is slidably connected with the lifting slide.

[0012] Furthermore, the horizontal plate is provided with an inclined baffle to maintain its smooth sliding, and the inclined baffle is located on the inner side of the side plate near the drilling assembly.

[0013] According to one specific embodiment of the present invention, the lifting driver is an electric drive module, a pneumatic drive module, or a hydraulic drive module.

[0014] According to a specific embodiment of the present invention, a mounting groove is provided on the horizontal plate, and there are two horizontal sliding grooves, which are arranged on opposite sides of the mounting groove; wherein, the drill bit module is disposed downward through the mounting groove.

[0015] This utility model has the following beneficial effects:

[0016] The fixing component of this invention provides a very convenient way to clamp the foundation pile. During alignment, the first and second semi-rings are respectively attached to the outer wall of the foundation pile, and then locked in place by the locking component to fix it to the top of the foundation pile.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Many specific details are set forth in the following description with reference to the embodiments in order to provide a full understanding of this utility model; however, it should be understood that the following embodiments and detailed descriptions are for illustrative purposes only and do not limit the scope of protection of this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The engineering foundation pile testing and fixing device in the embodiment is as follows: Figure 1-2 As shown, it includes a frame 10, a drilling assembly 20, and a fixing assembly 30. The frame 10 is mainly used as the main body for installation and support. It includes a side plate 11 and a horizontal plate 12. The horizontal plate 12 is vertically mounted on the side plate 11. For example, the side plate 11 is provided with a lifting slide 13. The horizontal plate 12 is slidably disposed in the lifting slide 13 and can move up and down under the drive of the lifting driver 14.

[0025] Specifically, the lifting driver 14 is a hydraulic drive module, such as a hydraulic cylinder; in other optional embodiments, the lifting driver 14 can also be an electric drive module, such as a motor, or a pneumatic drive module, such as a cylinder. To maintain the stability of the lifting of the horizontal plate 12, such as... Figure 3 As shown, the end 12a of the horizontal plate 12 connected to the side plate 11 is set in an "I" shape, and it is slidably connected to the lifting slide 13.

[0026] Furthermore, the horizontal plate 12 is provided with inclined baffles 121, which are located inside the side upright plate 11. There are two inclined baffles 121, which are used to better maintain the smooth sliding between the horizontal plate 12 and the lifting slide 13. In other embodiments, the horizontal plate 12 can also adopt, for example, the form of a slide rail to form a sliding fit with the side upright plate 11, which will not be elaborated here.

[0027] Please continue reading. Figure 1-3The drilling assembly 20 includes a sliding plate 21 and a drill bit module 22. A horizontal sliding groove 122 is provided on the horizontal plate 12. The sliding plate 21 is slidably installed into the horizontal sliding groove 122, and the drill bit module 22 is mounted on the sliding plate 21. Specifically, the sliding plate 21 is, for example, an inverted U-shaped plate. There are two horizontal sliding grooves 122, and the two sliding feet of the sliding plate 21 are supported within the horizontal sliding grooves 122 and can slide. Optionally, after the sliding plate 21 is fixed in its left or right position, it can be fixed to the horizontal plate 12 by means of, for example, locking bolts, thereby preventing its position from changing.

[0028] The horizontal plate 12 is provided with a mounting groove 123, and two horizontal sliding grooves 122 are provided on opposite sides of the mounting groove 123. The drill bit module 22 is disposed downward through the mounting groove 123 so that the drill bit module 22 can move downward and perform drilling. The drill bit module 22 is, for example, an electrically driven structure, which includes a motor 221 and a drill bit 222 mounted on the drive end of the motor 221. The drill bit can be replaced with different specifications as needed, and drilling and sampling are achieved by controlling the start and stop of the motor 221.

[0029] like Figure 1-2 , Figure 4 As shown, the fixing component 30 includes a first semi-ring 31, a second semi-ring 32, and a locking member; the first semi-ring 31 is disposed on the side plate 11 and located below the horizontal plate 12, and the second semi-ring 32 is arranged opposite to the first semi-ring 31 to form a working cavity 33, which is specifically cylindrical and matches the shape of the engineering foundation pile; wherein, at least one of the first semi-ring 31 and the second semi-ring 32 has a gasket 34 on its inner wall surface, the gasket 34 being, for example, made of silicone, with a rough inner wall, which helps to increase the friction effect on the surfaces of the first semi-ring 31 and the second semi-ring 32, thereby improving the clamping effect on the engineering foundation pile.

[0030] Please continue reading. Figure 4 The first half-ring 31 and the second half-ring 32 are each provided with a set of connecting lug plates 35. When the first half-ring 31 and the second half-ring 32 are joined together, the different lug plates 35 fit together. There are two sets of locking components. The two sets of locking components are respectively installed on the lug plates 35 on the first half-ring 31 to connect the second half-ring 32 to the first half-ring 31 and clamp the engineering foundation pile located in the working cavity 33.

[0031] The locking component includes a locking screw 36 and a nut 37 fitted on the locking screw 36. The second half-ring 32 has a locking screw 36 on its lug plate 35, and the first half-ring 31 has a through hole 311 on its lug plate 35. The locking screw 36 passes through the through hole 311 and is locked by the nut 37, thus achieving the locking of the first half-ring 31 and the second half-ring 32.

[0032] Furthermore, the locking component also includes an active push-pull rod 38, the two ends of which are connected to the first semi-ring 31 and the second semi-ring 32 respectively, for actively closing the first semi-ring 31 and separating the second semi-ring 32 in opposite directions, while maintaining the connection between the second semi-ring 32 and the first semi-ring 31. Specifically, the active push-pull rod 38 is, for example, an electric push rod. In other embodiments, the active push-pull rod 38 can also be a pneumatic push rod or a hydraulic push rod.

[0033] Correspondingly, the number of locking screws 36 on the pair of lifting lugs 35 on the same side is preferably two, and the two locking screws 36 are located on both sides of the active push-pull rod 38. This is conducive to maintaining the locking effect, and after the nuts 37 on the two locking screws 36 are fully locked, the active push-pull rod 38 can no longer provide locking force, which is beneficial to protecting the active push-pull rod 38.

[0034] The use of the same power source in the embodiment can ensure that the first half-ring 31 and the second half-ring 32 provide the same force to the engineering foundation pile when clamping it, thus avoiding the phenomenon that the stability of the engineering foundation pile is affected by uneven force on both sides.

[0035] The exemplary operation process of the engineering foundation pile testing and fixing device in this embodiment is as follows:

[0036] 1) The device is positioned and installed as a whole, so that the first half-ring 31 is attached to the outer wall of the completed engineering foundation pile, while the second half-ring 32 is not attached to the outer wall of the engineering foundation pile.

[0037] 2) Power on the device, the active push-pull rod 38 is activated and starts, driving the second half-ring 32 to move toward the first half-ring 31 and fit against the outer wall of the engineering foundation pile. During this process, the locking screw 36 remains through the through hole 311.

[0038] 3) Move the second half-ring 32 into place, screw the nut 37 onto the locking screw 36 and tighten it to complete the fixed connection between the device and the engineering foundation pile;

[0039] 4) Push the slide plate 21 to move so that the drill bit module 22 is positioned above the drilling position of the engineering foundation pile;

[0040] 5) Start the lifting drive 14 to drive the horizontal plate 12 to descend, which in turn drives the drill bit module 22 to descend slowly; at the same time, start the drill bit module 22 to begin drilling and sampling the engineering foundation pile.

[0041] Although the present invention has been described above through embodiments, the above embodiments are only used to exemplarily describe possible implementations of the present invention, and are not intended to limit the scope of protection of the present invention. Any equivalent substitutions or changes made by those skilled in the art in accordance with the present invention should also be covered by the scope of protection defined by the claims of the present invention.
