Description

Technical Field

[0001] This utility model belongs to the field of pile foundation technology, and in particular relates to a pile foundation reinforcement device. Background Technology

[0002] In recent years, there has been an increasing number of renovation projects for old industrial buildings, especially industrial plants, particularly in the reuse of concrete structures, which is a widely recognized and representative area. Building reuse and renovation projects refer to the full utilization of existing building structures, equipment, materials, and components during construction or renovation to reduce waste and costs, while extending the building's lifespan and improving its efficiency. Among these projects, the reinforcement of engineering piles is a key focus. An engineering pile consists of a pile body and a bearing platform connected to the top of the pile. The bearing platform supports the pile on the ground, and the load of the pile foundation is transferred to the foundation soil through the bearing platform. Currently, the reinforcement method for engineering piles involves casting concrete around the bearing platform to increase its area, thereby increasing the contact area between the bearing platform and the foundation soil to achieve a reinforcement effect. This method requires cast-in-place concrete, is complex to construct, and takes a long time for the concrete to reach its design strength, resulting in a long construction period for pile foundation reinforcement. Furthermore, this reinforcement method is not applicable when there is a significant height difference between the foundation soil and the pile foundation. Utility Model Content

Support components are installed on both sides of the bearing platform. Rotating the telescopic rod can drive the reinforcing rod at the bottom of the extension plate into the foundation soil for anchoring, thereby reinforcing the pile foundation, reducing the dynamic response of the pile foundation, and improving the seismic and wind resistance performance. This device is simple to install, has a short construction period, and the two extension plates at the bottom of the fixing frame can slide back and forth to adjust the anchoring position.

[0031] Example

[0032] Reference Figure 1-2 A pile foundation reinforcement device, comprising

[0033] Pile body 1;

[0034] The support platform 2 is connected to the top of the pile body 1;

[0035] The fixing cylinder 3 is sleeved on the pile body 1 and fixed to the top of the bearing platform 2;

[0036] Several support blocks 4 connect the outer side of the fixed cylinder 3 to the top of the support platform 2;

[0037] Two support components 6 are installed on both sides of the support platform 2. Each support component 6 includes a telescopic rod. One end of the telescopic rod is hinged to the support platform 2, and the other end of the telescopic rod is hinged to a fixed frame 604. Two extension plates 605 are slidably installed on the bottom front and rear sides of the fixed frame 604. Several reinforcing rods 606 are fixed to the bottom of the two extension plates 605.

[0038] In one specific implementation, hinge seats 601 are fixed on both sides of the support platform 2 and the top of the fixing frame 604, and the upper and lower parts of the telescopic rod are respectively connected to the two hinge seats 601 by pins.

[0039] In a specific implementation plan, refer to Figure 3 A specific telescopic structure for a telescopic rod is provided, wherein the telescopic rod includes a first adjusting cylinder 602 and a second adjusting cylinder 603;

[0040] A functional plate 608 is fixedly connected to the end of the first adjusting cylinder 602. The functional plate 608 is inserted into the second adjusting cylinder 603. A lifting plate 609 is connected to the surface of the functional plate 608 by a number of springs 611. A number of insert rods 610 are fixed to the surface of the lifting plate 609.

[0041] The second adjusting cylinder 603 has several slots on its inner wall surface opposite to the several insert rods 610, and the insert rods 610 are adapted to the slots;

[0042] The surface of the functional board 608 is also fixed with a mounting plate 612, and a locking rod 614 is rotatably mounted on the mounting plate 612 via a rotating shaft 613.

[0043] The telescopic length of the telescopic rod is adjusted by changing the distance between the first adjusting cylinder 602 and the second adjusting cylinder 603. When it is necessary to change the distance between the first adjusting cylinder 602 and the second adjusting cylinder 603, rotate the locking lever 614 to a position parallel to the lifting plate 609. At this time, the lifting plate 609 will lose the limiting effect of the locking lever 614. Then, through the reset action of the spring 611, the insertion rod 610 will disengage from the slot inside the second adjusting cylinder 603, thereby releasing the relative fixation between the first adjusting cylinder 602 and the second adjusting cylinder 603. Then, the second adjusting cylinder 603 can be pulled to adjust its distance from the first adjusting cylinder 602. After the adjustment is completed, rotate the locking lever 614 to a position that is perpendicular to the lifting plate 609. At this time, the lifting plate 609 will move towards the inner wall of the second adjusting cylinder 603, thereby driving the insertion rod 610 to insert into the slot in the inner wall of the second adjusting cylinder 603, realizing the relative fixation between the first adjusting cylinder 602 and the second adjusting cylinder 603.

[0044] In a specific implementation plan, refer to Figure 2 , Figure 4 The present invention provides a specific sliding structure for an extension plate 605, wherein the fixing frame 604 is a groove-shaped structure with an opening facing downwards, and the inner walls on both sides of the fixing frame 604 are provided with sliding grooves 615, and a stabilizing rod 616 is fixed on the upper surface of the extension plate 605, and the two ends of the stabilizing rod 616 are slidably installed in the sliding grooves 615 on both sides.

[0045] In one specific implementation, the top front and rear sides of the fixed frame 604 are respectively threaded with two fastening bolts 607. The top of the extension plate 605 has two rows of threaded holes. The fastening bolts 607 are adapted to the threaded holes. After the two extension plates 605 slide to a suitable position, the fastening bolts 607 are screwed into the threaded grooves to fix the two extension plates 605 relatively.

[0046] In one specific implementation, the support block 4 is a right-angled trapezoidal structure, which makes the connection between the fixed cylinder 3 and the bearing platform 2 stable, improves the compressive strength, and better bears the upper load.

[0047] In one specific implementation, the bottom of the support platform 2 has several drilling rods 5, which are driven into the foundation soil to assist in supporting the support platform 2.

[0048] The pile body 1 at the top of the bearing platform 2 of this utility model is fitted with a fixing cylinder 3. The fixing cylinder 3 is connected to the bearing platform 2 through several support blocks 4. This allows the load of the pile body 1 located on the upper structure of the bearing platform 2 to be distributed more evenly to the top surface of the bearing platform 2, reducing local stress concentration. Support components 6 are installed on both sides of the bearing platform 2. Rotating the telescopic rod can drive the reinforcing rod 606 at the bottom of the extension plate 605 into the foundation soil for anchoring, thereby reinforcing the pile foundation, reducing the dynamic response of the pile foundation, and improving the seismic and wind resistance performance. This device is simple to install, has a short construction period, and the two extension plates 605 at the bottom of the fixing frame 604 can slide back and forth to adjust the anchoring position. The extension and retraction of the telescopic rod makes this reinforcement device applicable to foundation soil at different heights around the pile foundation.

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.
