Description

Technical Field

[0001] This utility model relates to the technical field of positioning devices, and in particular to a positioning device for foundation pit support piles. Background Technology

[0002] During the excavation of a foundation pit, the surrounding soil will shift and deform inwards due to the unloading effect of the soil. If effective support measures are not taken, the foundation pit may collapse, landslide, or other accidents. Therefore, foundation pit support engineering plays a crucial role in ensuring the safety of foundation pit construction, controlling foundation pit deformation, and protecting the surrounding environment.

[0003] Currently, in the positioning of foundation pit support piles, as exemplified by the patent with prior art authorization announcement number CN219992489U, this utility model relates to the field of foundation pit support pile technology, and in particular to a foundation pit support pile stabilization device, comprising several support piles, with symmetrical fixing devices fixed on both sides of each support pile, and adjacent support piles connected by a crossbeam through the fixing devices; an auxiliary device is also provided on the support pile, with an arc plate of the auxiliary device clamped on the support pile, and positioning rods fixedly connected to both ends of the arc plate, the positioning rods being inserted into the soil.

[0004] However, during the use of the device, it was found that the device needs to rely on the sidewall of the pit to fix the support piles, which is highly dependent on the strength of the pit sidewall, reducing the reliability of the positioning of the support piles and reducing the safety of use. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a foundation pit support pile positioning device that supports the support pile by subjecting the ground on the side of the foundation pit to force, thereby effectively improving the positioning reliability and safety of the support pile and improving the convenience of supporting and positioning support piles of different heights.

[0006] This utility model discloses a positioning device for foundation pit support piles, comprising a base and a guide frame, with the guide frame installed at the top of the base; it also includes a positioning device, an adjustment device, a support device, a support platform, side plates, and multiple sets of guide columns. The support platform is slidably mounted on the guide frame, and the side plates are installed at the ends of the multiple sets of guide columns. The multiple sets of guide columns slide through the interior of the support platform. A positioning device is provided on the support platform to position the multiple sets of guide columns. An adjustment device is provided on the support platform to drive the side plates to move horizontally for adjustment. The support device is provided on the base to provide power for the sliding of the support platform. The base is fixed to the ground, and then the side plates are moved horizontally by the adjustment device, so that the side plates support and position the side of the support pile. At this time, the ground on the side of the foundation pit is subjected to force to support the support pile, thereby effectively improving the positioning reliability and safety of the support pile. By adjusting the support platform up and down, the convenience of supporting and positioning support piles of different heights is improved.

[0007] Preferably, the adjusting device includes an internally threaded sleeve, a stud, a housing, a worm gear, a worm wheel, and a handwheel. The internally threaded sleeve is rotatably mounted on the support platform. The stud is screwed onto the internally threaded sleeve, and the end of the stud is fixedly connected to the outer wall of the side plate.

The worm wheel is mounted on the outer wall of the internally threaded sleeve, and the worm wheel meshes with the worm gear. The handwheel is mounted on the end of the worm gear. By gripping the handwheel, the operator rotates the worm gear. After the worm gear rotates, it drives the internally threaded sleeve to rotate through the worm wheel. After the internally threaded sleeve rotates, it drives the stud to move horizontally, thereby causing the stud to move the side plate horizontally to support and position the support pile, improving the convenience of the positioning operation. At the same time, due to the meshing of the worm wheel and the worm gear, the locking effect of the internally threaded sleeve rotation is improved, and the support stability of the side plate for the support pile is improved.

[0008] Preferably, the positioning device includes multiple sets of components, multiple sets of handle screws, and multiple sets of limiting blocks. The multiple sets of components are all installed on the outer wall of the support platform. Multiple sets of guide posts slide through the multiple sets of components, and the multiple sets of handle screws are respectively fitted onto the multiple sets of components. The multiple sets of limiting blocks are respectively installed at the ends of the multiple sets of guide posts. By rotating and adjusting the multiple sets of handle screws, the sliding and pressing mechanisms of the guide posts are fixed, improving the positioning reliability of the side plate. By setting multiple sets of limiting blocks, the slippage of the multiple sets of guide posts is prevented, improving the limiting effect.

[0009] Preferably, the support device includes a jack, which is installed on the outer wall of the base, and the moving end of the jack is connected to the bottom end of the support platform; the jack supports the lifting and adjusting of the support platform, thereby improving the convenience of adjusting the height of the side plate.

[0010] Preferably, it also includes multiple sets of insertion rods, and the base is provided with multiple sets of through holes, through which the multiple sets of insertion rods pass; by inserting the multiple sets of insertion rods into the ground after passing through the base, the positioning effect of the base is improved.

[0011] Preferably, it also includes multiple sets of nails, all of which are located at the bottom of the base; by inserting multiple sets of nails into the ground, the pre-installation positioning convenience of the base is improved.

[0012] Preferably, it also includes a groove, which is provided on the side of the side plate; by providing the groove, the bending resistance of the side plate is improved, and the reliability of the support is improved.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the base is fixed on the ground, and then the side plate is moved horizontally by the adjustment device, so that the side plate supports and positions the side of the support pile. At this time, the support pile is supported by the ground on the side of the pit, thereby effectively improving the positioning reliability and safety of the support pile. By adjusting the support platform up and down, the convenience of supporting and positioning support piles of different heights is improved. Attached Figure Description
