Description

Technical Field

[0001] This utility model relates to the field of construction site testing technology, specifically to a bearing capacity testing platform for pile foundation testing. Background Technology

[0002] A pile foundation, also known as a pile base, is a common type of foundation used in building construction. It mainly consists of piles and pile caps. Piles are load-bearing structures that are vertically or inclinedly embedded in the ground, while pile caps are components that connect all the pile tops and evenly distribute the load of the superstructure. The main functions of pile foundations include load bearing, reducing settlement, earthquake resistance, ease of construction, and economy. There are various types of pile foundations. According to the construction method, they can be divided into precast piles and cast-in-place piles. According to the stress characteristics, they can be divided into end-bearing piles and friction piles. In practical engineering applications, the appropriate type of pile foundation is selected based on specific geological conditions, project requirements, and economic benefits.

[0003] Pile foundation bearing capacity testing is an important measure to ensure the quality of pile foundation engineering and the safety of buildings. Pile foundation bearing capacity testing usually adopts static load test, which loads a weight on the top of the pile to test the bearing capacity of the pile foundation. When carrying out static load test, it is necessary to concentrate the weight of the weight on the pile and ensure the stability of the test structure. Because hydraulic jacks are prone to displacement under the influence of external forces, the bearing capacity test platform may collapse. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a bearing capacity testing platform for pile foundation testing, which solves the problems mentioned above.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a bearing capacity testing platform for pile foundation testing, comprising a supporting base plate, a pile foundation, a centering positioning iron plate, a hydraulic jack, a steel beam, sleepers, and a static load counterweight. The supporting base plate is arranged around the pile foundation, with the pile foundation located in the middle of the supporting base plate. The steel beam is installed on the upper end of the pile foundation via the hydraulic jack and the centering positioning iron plate. The sleepers are located between the steel beam and the static load counterweight to ensure that the height of the steel beam is consistent with that of the supporting base plate. The static load counterweight is installed at the top of the steel beam and the supporting base plate. The centering positioning iron plate comprises an iron plate and a centering locator, with the center position of the iron plate being snap-fitted to the centering locator.

[0008] Preferably, the iron plate includes an outer shell and square holes. Four square holes are centrally located on the outer shell, and are symmetrically positioned at the center of the outer shell. The interiors of the four square holes are smooth and coated with lubricating oil to ensure the sliding of the centering locator on the iron plate. The lubricating oil prevents rust and jamming.

[0009] Preferably, the centering positioner includes a positioning component, a telescopic rod, and a connecting component. The bottom of the positioning component is fixedly connected to the telescopic rod through the connecting component. The two telescopic rods are parallel and at the same height to ensure that the centering positioning plate is not subjected to longitudinal external force, thereby improving the effective power.

[0010] Preferably, the positioning component includes a positioning block, an L-shaped rotating shaft, and a rotating connecting plate. The positioning block is rotatably connected to the rotating connecting plate via the L-shaped rotating shaft. The upper inner surface of the positioning block is rough and has friction to improve grip and prevent the hydraulic jack from rotating and slipping.

[0011] Preferably, the telescopic rod includes a telescopic tubular outer shell and a telescopic long rod. The telescopic tubular outer shell is inserted into the telescopic long rod, and the inner walls of the telescopic long rod and the telescopic tubular outer shell are in close contact with each other, with smooth contact surfaces, to ensure that the telescopic rod can extend and retract with ease, and to prevent equipment from shaking.

[0012] Preferably, the connecting assembly includes a connecting rod, a first connecting block, and a second connecting block. The first connecting block is fixedly connected to the second connecting block via the connecting rod. The two connecting assemblies are symmetrical. The connecting rod is straight, of equal length, and has low deformation capacity, ensuring the level of the centered positioning iron plate and preventing the hydraulic jack from tilting and affecting the data.

[0013] (III) Beneficial Effects

[0014] This utility model provides a bearing capacity testing platform for pile foundation testing. It has the following advantages: by setting a centering positioning plate, which is installed between the steel beam and the pile foundation, the hydraulic jack is positioned using a centering locator within the plate, thus achieving fixation and centering of the hydraulic jack and improving the stability of the equipment.

[0026] Please see Figure 1 and Figure 2 This utility model provides a technical solution for a bearing capacity testing platform for pile foundation testing: A bearing capacity testing platform for pile foundation testing includes a supporting base plate 1, a pile foundation 2, a centering positioning iron plate 3, a hydraulic jack 4, a steel beam 5, sleepers 6, and a static load counterweight 7. The supporting base plate 1 is arranged around the pile foundation 2, and the pile foundation 2 is located in the middle of the supporting base plate 1. The steel beam 5 is installed on the upper end of the pile foundation 2 through the hydraulic jack 4 and the centering positioning iron plate 3. The sleepers 6 are located between the steel beam 5 and the static load counterweight 7 to make the height of the steel beam 5 consistent with that of the supporting base plate 1. The static load counterweight 7 is installed at the top of the steel beam 5 and the supporting base plate 1. The centering positioning iron plate 3 includes an iron plate 31 and a centering positioner 32. The center position of the iron plate 31 is snapped together with the centering positioner 32.

[0027] Please see Figure 2The iron plate 31 includes an iron plate outer shell 311 and four square holes 312. Four square holes 312 are centrally located on the iron plate outer shell 311. These holes are symmetrically positioned at the center of the outer shell 311, and the interiors of the four square holes 312 are smooth and lubricated to ensure the sliding of the centering positioner 32 on the iron plate 31. The lubricating oil prevents rust and jamming.

[0028] Please see Figure 3 The centering positioner 32 includes a positioning component 321, a telescopic rod 322, and a connecting component 323. The bottom of the positioning component 321 is fixedly connected to the telescopic rod 322 through the connecting component 323. The two telescopic rods 322 are parallel and at the same height, ensuring that the centering positioning iron plate 3 is free from longitudinal external force and improving effective power. The positioning component 321 includes a positioning block 3211, an L-shaped rotating shaft 3212, and a rotating connecting plate 3213. The positioning block 3211 is rotatably connected to the rotating connecting plate 3213 through the L-shaped rotating shaft 3212. The upper inner surface of the positioning block 3211 is rough and has friction to improve grip and prevent the hydraulic jack 4 from rotating and slipping.

[0029] Please see Figure 4 The telescopic rod 322 includes a telescopic tubular outer shell 3221 and a telescopic long rod 3222. The telescopic tubular outer shell 3221 is inserted into the telescopic long rod 3222. The inner walls of the telescopic long rod 3222 and the telescopic tubular outer shell 3221 fit together and the contact surface is smooth, ensuring that the telescopic rod 322 can extend and retract with ease and preventing equipment from shaking.
