Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation detection, in particular to a pile foundation quality detection device. Background Art

[0002] Pile foundation is a building component used for bearing loads. After the pile foundation construction is completed, it is necessary to conduct quality inspections. One of the inspections is a static load test. The static load test is to apply downward pressure on the pile foundation and then monitor its settlement to determine whether its bearing capacity meets the requirements of the specifications. During the static load test of the pile foundation, the pile foundation may tilt slightly due to soil reasons during the continuous stress process, resulting in uneven stress at the top of the pile foundation, affecting the test results. In addition, after the test is completed, it is impossible to determine whether the pile foundation is tilted by naked eye observation, which will affect the test judgment of the staff, resulting in data errors.

[0003] In view of this, a design or technical improvement is now proposed to solve the above problems.

[0004] The above contents are only used to assist in understanding the technical solution of the present utility model, and do not constitute an admission that the above contents are the closest prior art. Utility Model Content

[0020] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] like Figure 1-4A pile foundation quality inspection device shown in the figure comprises an outer hanging ring plate 1 sleeved on the outer side of the pile foundation and a supporting assembly for fixing the outer hanging ring plate 1; a plurality of groups of movable push rods 2 that are movable along the radial limit of the outer hanging ring plate 1 are evenly arranged on the outer hanging ring plate 1. During the static load test of the pile foundation, the movable push rods 2 are pressed against the outer surface of the pile foundation. When the pile foundation tilts after the test, the movable push rods 2 on the corresponding side will be supported to move. Then, the staff can observe whether the pile foundation is tilted according to the moving distance of the movable push rods 2 after the test, and then judge the accuracy of the test data.

[0022] In one embodiment, the support assembly includes a support foot 11 arranged on the lower surface of the external hanging ring plate 1 and an adjustment pile 12 threadedly connected to the support foot 11. Before using this device, it is first necessary to ensure the horizontality of the device, so as to adjust the support foot 11 by rotating the adjustment pile 12 to ensure that the external hanging ring plate 1 is in a stable horizontal state.

[0023] In one embodiment, a supporting ring plate 3 is further provided on the outer side of the supporting foot 11, and linkage plates 31 are evenly distributed on the supporting ring plate 3. One end of the linkage plate 31 is hinged to the supporting ring plate 3 and the other end is hinged to the movable top rod 2. Through the setting of the linkage plate 31, the movable top rod 2 will drive the linkage plate 31 to tilt after the movement, so as to facilitate observation by the staff.

[0024] In one embodiment, the movable push rod 2 includes a threaded sleeve 21 hinged to the linkage plate 31 and a push rod 22 threadedly connected to the threaded sleeve 21 and movably connected to the outer hanging ring plate 1. The push rod 22 is hemispherical at one end facing the center of the circle of the outer hanging ring plate 1. After the device is installed, the linkage plate 31 needs to be vertically leveled first, and it is prioritized to ensure that it is in an absolutely vertical state. Then, by rotating the push rod 22, it is telescopic and movable in the threaded sleeve 21, so as to adapt to pile foundations of different specifications, so that the push rod 22 can be attached to the surface of the pile foundation. When the pile foundation is skewed, the push rod 22 will be pushed and drive the linkage plate 31 to make active feedback.

[0025] In one embodiment, measuring plates 4 located on one side of the linkage plate 31 are evenly distributed on the supporting ring plate 3, an arc-shaped groove 41 is provided on the measuring plate 4, and an indicator rod 42 that slides within the arc-shaped groove 41 is provided on the linkage plate 31. The upper end of the measuring plate 4 is marked with a scale. When the pile foundation tilts and the linkage plate 31 is driven to tilt synchronously through the movable top rod 2, the indicator rod 42 at its upper end will slide within the arc-shaped groove 41, thereby facilitating observation by the staff, and also enabling the staff to make a rough judgment on the degree of tilt, thereby facilitating them to determine whether a secondary test is needed.

[0026] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
