Description

Technical Field

[0001] This utility model relates to the field of static load testing technology for pile pull-out resistance, and in particular to an auxiliary accessory for testing the vertical bearing capacity of piles. Background Technology

[0002] Since ground-based foundation piles are mostly constructed on hillsides, deserts, wastelands, fields, tidal flats, and swamps, they serve as a crucial structure for photovoltaic power stations, bearing the weight of the support structure and photovoltaic modules, and resisting all dynamic loads, including wind loads, snow loads, rain loads, and seismic loads. Under dynamic loads, if the foundation piles are unstable, the support structure may experience uplift, displacement, uneven settlement, or breakage, severely impacting the normal operation and lifespan of the photovoltaic power station. Therefore, in the construction of photovoltaic power stations, it is extremely important to emphasize the control and testing of the bearing capacity of the foundation piles, both in the design and construction phases.

[0003] Currently, static load testing of foundation piles faces two main challenges: either the heavy static load testing equipment increases the difficulty of testing due to the fact that ground-mounted photovoltaic power stations are mostly built in the field, and the need to use cranes for hoisting, setting up, and dismantling is troublesome and time-consuming, which is not conducive to saving construction time and costs; or the measurement is fixed on the top of the foundation, which is inconvenient to fix, requires the construction of high frames to support the jacks, is inefficient and unsafe, and requires operators to climb on the foundation pile to fix the device, which is time-consuming, labor-intensive and poses safety risks. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary accessory for testing the vertical bearing capacity of foundation piles, so as to solve the problems existing in the prior art. It is not only simple in structure and easy to operate, but also can significantly reduce the testing period and testing cost.

[0005] To achieve the above objectives, this utility model provides the following solution: This utility model provides an auxiliary accessory for testing the vertical bearing capacity of a foundation pile, including clamps symmetrically arranged on both sides of the foundation pile. Each clamp has a connecting plate along its two outer edges. The connecting plates of the two clamps are connected by a connector and tightened around the outer periphery of the foundation pile. A support beam is provided on the outer side of the clamp, and a jack abuts against the bottom of the support beam and is used to apply a vertical load to the support beam.

[0006] In one embodiment, the shape of the clamp matches the shape of the foundation pile.

[0007] In one embodiment, the clamp is a semi-circular or semi-rectangular structure.

[0008] In one embodiment, the connecting plate is welded along its entire length to the outer edge of the clamp.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The purpose of this invention is to provide an auxiliary accessory for testing the vertical bearing capacity of foundation piles, so as to solve the problems existing in the prior art. It is not only simple in structure and easy to operate, but also can significantly reduce the testing period and testing cost.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1-3 As shown, this utility model provides an auxiliary accessory for testing the vertical bearing capacity of a foundation pile, including clamps 1 symmetrically arranged on both sides of the foundation pile. Each clamp 1 has a connecting plate 4 on its two outer edges. The connecting plates 4 of the two clamps 1 are connected by a connector and tightened around the outer periphery of the foundation pile. A support beam 5 is provided on the outer side of the clamp 1. A jack 6 abuts against the bottom of the support beam 5 and is used to apply a vertical load to the support beam 5.

[0024] like Figure 1 As shown, the device includes two clamps 1 symmetrically arranged on both sides of the foundation pile (not shown in the figure). Connecting plates 4 are provided on the outer edges of the two clamps 1. After the connectors pass through the connecting holes 3 of the two connecting plates 4, the two clamps 1 are fixed to the outer periphery of the foundation pile, so that the two clamps 1 hold the foundation pile tightly. Then, the jack 6 is used to apply an upward force to the support beam 5. This force is transmitted to the foundation pile through the support beam 5 and the clamps 1, thereby applying a vertical tensile load to the foundation pile. The measurement method of this device is simple and can be completed on the ground. There is no need for operators to climb up to fix it, which saves time and effort, reduces costs, and is safe and reliable.

[0025] In one embodiment, the shape of the clamp 1 matches the shape of the pile; the clamp 1 is a semi-circular or semi-rectangular structure. Figures 1-3 The image shows a semi-circular clamp 1. The shape of the clamp 1 can be adjusted according to the actual shape of the foundation pile so that the inner side of the clamp 1 can adapt to the shape of the foundation pile and achieve a tight grip.

[0026] In one embodiment, in order to improve the tightness and stability of the connection between the two clamps 1, the connecting plate 4 is welded along the entire length of the outer edge of the clamp 1, and a stiffening rib 2 is welded between the outer side of the connecting plate 4 and the outer peripheral surface of the clamp 1.

[0027] In one embodiment, the connecting plate 4 has a connecting hole 3, and the connecting component is a bolt 7. The bolt 7 is used to pass through the connecting hole 3 on the two clamps 1 and fix the two clamps 1 together. In actual use, other connection methods can also be selected according to the actual environment, such as buckles or other easy-to-operate connection methods.

[0028] In one embodiment, the support beam 5 is made of I-beams and is welded to the clamp 1. On one hand, the clamp 1, the I-beam, and the connecting plate 4 form the main body of the auxiliary component, all connected by welding. This provides better structural stability for the entire auxiliary component used to test the vertical bearing capacity of the foundation pile. When the jack 6 applies a vertical load, the integrally welded auxiliary component can better transfer the vertical load to the foundation pile. Furthermore, the I-beam structure provides a large contact area on the bottom surface of the support beam 5, allowing the jack 6 to better apply force to the support beam 5 and exert vertical loads. Additionally, because the jack 6 indirectly transfers the force to the foundation pile through the support beam 5 and the clamp 1, the force can be balanced by the I-beam support beam 5 during the force transmission process, thus allowing the force to be applied more evenly to the foundation pile and improving the accuracy of the pull-out test.

[0029] In one embodiment, a crossbeam is placed on the ground, the bottom of the jack 6 is placed on the crossbeam, and the ejector section of the jack 6 is in contact with the bottom surface of the support beam 5.

[0030] The following is a magnified view of the auxiliary accessories used for testing the vertical bearing capacity of foundation piles in this invention:

[0031] The clamp 1 consists of two parts, each semi-circular in shape. Connecting plates 4 are located on both sides of the semi-circle. Reinforcing ribs are added between the connecting plates 4 and the clamp 1 to provide stress relief. An I-beam is welded to the outer center of the semi-circle. In use, the clamp 1 holds the foundation pile, bolts 7 secure the connecting plates 4, and a crossbeam (either timber or steel) is placed on the ground. The test jack 6 is then placed between the crossbeam and the I-beam, and pressure is applied by the jack 6 for testing.
