Description

Technical Field

[0001] The invention belongs to the technical field of construction engineering, and in particular relates to a height compensation device for preventing pile foundation settlement. Background Art

[0002] Ground buildings, such as high-rise buildings and bridges, often use pile foundations as supporting foundations. The bearing capacity of pile foundations usually consists of two parts: one is the side friction resistance generated by the contact between the soil and the side of the pile foundation, and the other is the pile end resistance generated by the contact between the bottom surface of the pile foundation and the soil.

[0003] When the soil beneath the pile foundation sinks, the supporting force on the pile foundation becomes insufficient, causing the pile foundation to sink. This can lead to a decrease in the height of the building above the pile foundation, resulting in height differences, uneven stress distribution, cracks, and potential safety hazards. Therefore, the present invention provides a height compensation device for preventing pile foundation sinking. Summary of the Invention

[0004] The object of the present invention is to provide a height compensation device for preventing pile foundation settlement. Through the action of the top load-bearing seat, the strong elastic seat, the bottom load-bearing seat and the pin mechanism, when the soil layer below the pile foundation sinks to a certain extent, the pin mechanism disengages from the through hole A between the top load-bearing seat and the strong elastic seat, thereby compensating for the height difference of the settlement; when the soil layer sinks further, similarly, the pin mechanism disengages from the through hole B between the bottom load-bearing seat and the strong elastic seat, thereby further compensating for the height difference of the settlement; thereby solving the settlement problem mentioned above.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a height compensation device for preventing pile foundation settlement, comprising a top load-bearing seat, a strong elastic seat, a bottom load-bearing seat and a bayonet mechanism; the top and bottom of the strong elastic seat are respectively slidably matched with the top load-bearing seat and the bottom load-bearing seat, and are respectively provided with through holes A and through holes B; the strong elastic seat is fixedly connected to the top load-bearing seat and the bottom load-bearing seat by a strong spring; the bayonet mechanism comprises a settlement column, a hinged rod and a bayonet column; the top and middle parts of the settlement column are hinged to two hinged rods; the outer end of each hinged rod is hinged to a bayonet column; the through holes A and through holes B are both slidably matched with bayonet columns; the settlement column passes through the strong elastic seat and the bottom load-bearing seat, and is slidably matched with them.

[0007] Among them, the settlement column is set to be relatively heavy and the bottom force-bearing area is relatively small. A counterweight block can be fixed inside the settlement column or on the surrounding side to increase its mass. The thickness of the bottom can be set to be relatively thin, so that the pressure at the force-bearing position at the bottom of the settlement column is greater than the pressure at the force-bearing position at the bottom surface of the bottom bearing seat; thereby, when the soil layer below the pile foundation sinks to a certain extent, the settlement column will follow the decline first, and the degree of decline of the settlement column is relatively greater than the overall degree of decline of the height compensation device for pile foundation anti-settlement of the present invention, and then the pin mechanism disengages from the through hole A between the top bearing seat and the strong elastic seat to achieve the height difference of compensation for settlement; when it sinks further, similarly, the pin mechanism disengages from the through hole B between the bottom bearing seat and the strong elastic seat to achieve the height difference of further compensation for settlement; the problem of pile foundation settling one after another during settlement is solved.

[0008] Among them, the sum of the elastic forces of all the strong springs inside the top load-bearing seat and the strong elastic seat, and the sum of the elastic forces of all the strong springs inside the bottom load-bearing seat and the strong elastic seat are both greater than the pressure that the height compensation device for pile foundation anti-settlement of the present invention can withstand.

[0009] Furthermore, the top load-bearing seat and the bottom load-bearing seat are both cylindrical structures.

[0010] Furthermore, the outer diameter length of the top of the strong elastic seat is equal to the inner diameter length of the top load-bearing seat; the inner diameter length of the bottom of the strong elastic seat is equal to the outer diameter length of the bottom load-bearing seat.

[0011] Furthermore, a hinge seat A is provided on the top of the settlement column; and a rotating shaft A is fitted on the hinge seat A.

[0012] Furthermore, a movable groove is provided in the middle of the sedimentation column; a rotating shaft B is fitted in the movable groove.

[0013] Furthermore, an inner end surface of the latch column is provided with a hinged movable groove.

[0014] Furthermore, a central column hingedly matched with the hinge rod is fixed in the hinged movable groove.

[0015] Furthermore, the outer ends of the pair of hinged rods are both configured as connecting seats A.

[0016] Furthermore, the inner ends of the pair of hinged rods are respectively configured as a connecting seat B and a hinge seat B.

[0017] Furthermore, the bottom of the sedimentation column is configured as a conical structure.

[0018] The present invention has the following beneficial effects:

[0019] The present invention utilizes the functions of the top load-bearing seat, the strong elastic seat, the bottom load-bearing seat and the bayonet mechanism. When the soil layer below the pile foundation sinks to a certain extent, the bayonet mechanism disengages from the through hole A between the top load-bearing seat and the strong elastic seat, thereby achieving the advantage of compensating for the height difference of the settlement; when the soil layer sinks further, the bayonet mechanism disengages from the through hole B between the bottom load-bearing seat and the strong elastic seat, thereby achieving the advantage of further compensating for the height difference of the settlement.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
