Description

Technical Field

[0001] This utility model relates to the technical field of foundation exploration equipment, specifically to a foundation bearing capacity distance re-exploration device. Background Technology

[0002] A foundation bearing capacity re-survey device is used to re-examine and evaluate the bearing capacity of a foundation. Through periodic or irregular re-surveys, changes in foundation bearing capacity over time can be monitored, allowing for the timely detection of issues such as foundation settlement and soil layer movement. For example, in areas with complex geological conditions, the foundation bearing capacity may change due to factors such as groundwater level fluctuations and surrounding construction; this device allows for timely monitoring of these changes. Foundation bearing capacity testing typically employs methods such as direct penetration testing, static cone penetration testing, dynamic cone penetration testing, and ultrasonic transmission testing. Among these, the static cone penetration tester is one of the most commonly used devices for assessing foundation bearing capacity using the static cone penetration testing method.

[0048] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0049] Example 1

[0050] This embodiment provides a foundation bearing capacity distance resurvey device, such as... Figures 1-5 As shown, the fixed-distance resurvey device includes a body 1, with crossbeams 11 rotatably mounted on the left and right sides of the body 1, and quick-assembly structures 2 mounted on the crossbeams 11.

[0051] The quick-installation structure 2 includes a support frame 21. A bidirectional lead screw 22 is rotatably mounted on the front and rear sides of the support frame 21 via bearings. An L-shaped limiting plate 23 is threaded onto the front and rear sides of the bidirectional lead screw 22. A fixing plate 24 is symmetrically mounted on the inner end face of the support frame 21. A ground anchor 25 is mounted on the support frame 21 through a threaded hole. The ground anchor 25 can be rotated and moved up and down on the support frame 21 by means of the threaded hole.

[0052] In use, the operator moves the support frame 21 above the crossbeam 11, aligning the L-shaped limiting plates 23 on both sides with the two sets of slots 111 on the lower side. The support frame 21 is then moved downwards, causing the two sets of L-shaped limiting plates to fall into the two sets of slots 111. The lower end of the ground anchor rod 25 enters the inner cavity of the crossbeam 11. Next, the crank 221 is turned clockwise, driving the double-acting screw 22 to rotate. Simultaneously, the double-acting screw 22 moves the L-shaped limiting plates 23 closer together, causing the two sets of L-shaped limiting plates 23 to enter the slots 111 and lock them in place. The operator then turns the lever... 251, the wrench 251 rotates on the support frame 21 with the ground anchor rod 25, the lower end of the ground anchor rod 25 is driven into the soil, thus realizing the function of rapid installation of the static cone penetrometer. Then, the probe is driven into the foundation by the probe rod on the body 1 to realize the re-examination of the foundation bearing capacity. This avoids the problem of the cumbersome installation method of the static cone penetrometer in the prior art, which is to first drive the ground anchor into the soil and then use bolts and fasteners to fix the two crossbeams 11 of the static cone penetrometer body to the two ground anchor rods 25 on both sides. This simplifies the installation method and improves the installation efficiency.

[0053] In this embodiment, the front end of the bidirectional lead screw 22 passes through the support frame 21 and is equipped with a crank 221. A through hole 241 is opened on the fixing plate 24 corresponding to the bidirectional lead screw 22. A wrench 251 is installed on the upper end of the ground anchor rod 25. The crossbeam 11 is provided with a slot 111 adapted to the L-shaped limiting plate 23, and a positioning slot 112 for installing the fixing plate 24 is opened on the crossbeam 11.

[0054] With the positioning groove 112, when the quick-installation structure 2 is moved onto the crossbeam 11, the fixing plate 24 is aligned vertically with the positioning groove 112 and moved until the fixing plate 24 enters the positioning groove 112, which can realize the quick installation and positioning of the quick-installation structure 2, which is conducive to improving the installation and use efficiency of the body 1.

[0055] In this embodiment, the front end of the bidirectional lead screw 22 is a left-handed lead screw, and the rear end of the bidirectional lead screw 22 is a right-handed lead screw.

[0056] Example 2

[0057] Unlike Embodiment 1, the crossbeam 11 of the existing static penetrometer does not have a folding function, making the static penetrometer very inconvenient to transport. Therefore, connecting frames 3 are symmetrically installed on the left and right sides of the body 1. A sleeve 4 connected to the crossbeam 11 is rotatably installed on the outer wall of the connecting frame 3. A connecting block 5 is installed on the crossbeam 11 and on one side of the sleeve 4. Round rods 6 are slidably installed on the left and right sides of the body 1 through the mounting groove 12. A ring plate 7 is installed on the outer wall of the round rod 6. A spring 8 is installed on the ring plate 7 and outside the round rod 6.

[0058] In use, the operator rotates the crank 221 counterclockwise, and the two-way screw 22 moves the two sets of L-shaped limiting plates 23 away synchronously. The L-shaped limiting plates 23 are removed from the slot 111, thus realizing the disassembly function of the quick-assembly structure 2. Then, the pull rod 71 is moved away from the connecting block 5. The pull rod 71 drives the round rod 6 to move. The round rod 6 drives the ring plate 7 to compress the spring 8. At the same time, the round rod 6 is removed from the insertion hole 51 and loses control from the connecting block 5. The crossbeam 11 is rotated towards the body 1, realizing the function of folding the crossbeam 11. This reduces the storage space of the static cone penetrometer, facilitates its movement and transportation, and avoids the problem that the crossbeam 11 of the static cone penetrometer in the prior art does not have a folding function, making the static cone penetrometer very inconvenient to transport. This makes the use effect of the foundation bearing capacity distance resurvey device better.

[0059] In this embodiment, the outer wall of the connecting block 5 is provided with an insertion hole 51 that is compatible with the round rod 6, and the body 1 is connected to the other end of the spring 8 through the mounting groove 12; the outer wall of the ring plate 7 is provided with a pull rod 71, and the body 1 is provided with an opening 13 corresponding to the pull rod 71;

[0060] The opening 13 allows the pull rod 71 to move the ring plate 7 left and right, thus enabling the fixing and unlocking of the connecting block 5, and allowing the crossbeam 11 to be unfolded and folded.

[0061] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
