Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation bearing capacity detection, in particular to a pile foundation construction bearing capacity detection device in a karst area. Background Art

[0002] The bearing capacity of a pile foundation refers to the load that the pile foundation can withstand. It is crucial to the safety of engineering structures such as buildings and bridges. The strength of the pile material directly affects the bearing capacity of the pile foundation. For example, the stronger the concrete pile, the greater its bearing capacity is usually. The diameter and length of the pile also have an important impact on the bearing capacity. Generally speaking, the larger the pile diameter and the longer the pile length, the higher the bearing capacity.

[0003] When testing the bearing capacity of existing devices, heavy objects such as stones are usually hoisted by a crane and placed on the top of the pile foundation to test the bearing capacity. However, this testing method can only test the vertical bearing capacity. When the pile foundation is in use, it not only needs to bear vertical loads, but also lateral loads, which leads to incomplete testing.

[0030] The present application is further described in detail below through drawings and examples.

[0031] Reference Figures 1 to 4 The embodiment of the present application provides a bearing capacity detection device for pile foundation construction in a karst area, comprising a frame 1, an adjustment component 3 is arranged on the top of the frame 1, a detection component 2 is arranged on the side of the adjustment component 3, and a stabilization component 4 is arranged at the four corners of the outer side of the frame 1.

The detection component 2 comprises an adjustment plate 21, and the adjustment plate 21 is hinged on the left side of the mounting plate 31, and a hydraulic rod 22 is fixedly installed on the left side of the adjustment plate 21, and a pressure head 25 is fixedly installed on the bottom of the hydraulic rod 22. A top plate 24 is fixedly installed on the top of the adjustment plate 21, and the top of the hydraulic rod 22 is fixedly installed on the bottom of the top plate 24. A fixed block 23 is fixedly installed on the left side of the adjustment plate 21, and the fixed block 23 is fixedly installed on the outer side of the hydraulic rod 22.

[0032] A reinforcing plate 38 is fixedly installed at the bottom of the mounting plate 31. The reinforcing plate 38 is attached to the left side of the vehicle frame 1. A reinforcing rib 39 is fixedly installed between the left side of the reinforcing plate 38 and the bottom of the mounting plate 31. Two side plates 36 are fixedly installed at the top of the mounting plate 31. A first screw rod 35 is rotatably connected between the two side plates 36. A slider 34 is screwed to the outside of the first screw rod 35. The slider 34 is slidably connected to the top of the mounting plate 31. A pull rod 33 is hinged between the top of the slider 34 and the right side of the adjustment plate 21. A first motor 37 is fixedly installed on the right side of the detection component 2 of the right side plate 36. The output end of the first motor 37 movably passes through the inside of the side plate 36 and is fixedly connected to the first screw rod 35.

[0033] In this embodiment, when detecting the bearing capacity of the pile foundation, the vehicle frame 1 is moved as a whole to the vicinity of the pile foundation, the hydraulic rod 22 and the pressure head 25 are moved above the pile foundation, the pressure head 25 is driven to move downward by starting the hydraulic rod 22, and the top of the pile foundation is squeezed by the pressure head 25. The bearing capacity of the pile foundation can be detected by applying downward pressure to the pile foundation, which is more convenient than the detection operation by hoisting stones. Before the detection, the first motor 37 can be started to drive the first screw 35 to rotate. The rotation of the first screw 35 can drive the slider 34 to move along the lower mounting plate 31. The movement of the slider 34 can pull the pull rod 33 to move. By pulling the pull rod 33, the adjustment plate 21 can be driven to rotate along the connection between it and the mounting plate 31, so that the angles of the hydraulic rod 22 and the pressure head 25 can be adjusted. By adjusting the angle of the hydraulic rod 22, the direction in which the pressure is applied by the hydraulic rod 22 can be changed, so that the bearing capacity of the pile foundation at different angles can be detected.

[0034] Reference Figures 1 to 4 In one aspect of the present embodiment, the stabilizing assembly 4 includes an extension plate 41, which is fixedly mounted on the outside of the four corners of the frame 1, and a second screw rod 43 is threadedly penetrated inside the extension plate 41, and a spiral blade 42 is fixedly mounted at the bottom of the second screw rod 43 and below the extension plate 41.

A second motor 45 is fixedly installed on the top of the moving plate 44. The output end of the second motor 45 movably passes through the interior of the moving plate 44 and is fixedly connected to the second screw 43 below.

[0036] In this embodiment, before the detection, after the frame 1 moves to the fixed position, the second motor 45 can be started to drive the second screw 43 to rotate. The second screw 43 limits the movable plate 44 through the limit rod 46 while rotating, so that the second screw 43 can rotate and move downward at the same time, thereby driving the spiral blade 42 below to rotate and move downward at the same time, so that the spiral blade 42 can be screwed into the soil below. By screwing the spiral blade 42 into the bottom of the soil, the stability of the frame 1 supported on the ground can be improved, thereby ensuring the stability of the frame 1 during detection.

[0037] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0038] Working principle: When testing the bearing capacity of the pile foundation, the vehicle frame 1 is moved as a whole to the vicinity of the pile foundation, the hydraulic rod 22 and the pressure head 25 are moved above the pile foundation, the pressure head 25 is driven downward by starting the hydraulic rod 22, and the top of the pile foundation is squeezed by the pressure head 25. The bearing capacity of the pile foundation can be tested by applying downward pressure to the pile foundation, which is more convenient than testing by hoisting stones. Before testing, the first motor 37 can be started to drive the first screw 35 to rotate. The rotation of the first screw 35 can drive the slider 34 to move along the lower mounting plate 31. The movement of the slider 34 can pull the pull rod 33 to move. By pulling the pull rod 33, the adjustment plate 21 can be driven to rotate along the connection between it and the mounting plate 31, so that the hydraulic The angles of the rod 22 and the pressure head 25 can be adjusted. By adjusting the angle of the hydraulic rod 22, the direction in which the pressure is applied by the hydraulic rod 22 can be changed, thereby realizing the detection of the bearing capacity of the pile foundation at different angles; before the detection, after the frame 1 is moved to the fixed position, the second motor 45 can be started to drive the second screw 43 to rotate. While the second screw 43 is rotating, the movable plate 44 is limited by the limit rod 46, so that the second screw 43 can be rotated and moved downward at the same time, thereby driving the lower spiral blade 42 to rotate and move downward at the same time, so that the spiral blade 42 can be screwed into the soil below. By screwing the spiral blade 42 into the bottom of the soil, the stability of the frame 1 supported on the ground can be improved, thereby ensuring the stability of the frame 1 during detection.
