A static load testing platform with dust-collection functionality

Sep 23,2021

Samples must be tested before they are used. Improper use without a clear understanding of the template’s compressive performance can lead to serious safety incidents. Furthermore, some static load testing rigs lack dust-collection and sample-conveying capabilities, resulting in unreliable test results and low testing efficiency.

  A static load test is a testing method in which vertical compressive load, vertical uplift load, or horizontal push force is applied incrementally at the pile top, while monitoring the corresponding settlement, uplift displacement, or lateral displacement of the pile top over time, in order to determine the respective single-pile vertical compressive bearing capacity, vertical uplift bearing capacity, or horizontal bearing capacity. The static load test is the fundamental method for determining the axial compressive bearing capacity of a single pile, and its results are often used as the basis for evaluating the reliability of other testing methods. Therefore, when pile foundations are employed, particularly for important or special bridges, the axial compressive bearing capacity of individual piles should be determined through static load tests. At present, there are no stringent standards on the market for testing the compressive performance of various types of construction formwork, resulting in widely varying quality among different products. Before such formwork is put into use, samples must be tested. If formwork is used indiscriminately without first understanding its compressive performance, serious safety accidents may occur. Some Static Load Test Bench It lacks the functions of dust collection and sample conveyance, resulting in low reliability and low efficiency of test results.

  

 Static Load Test Bench


  To address the shortcomings of existing technologies, technicians have developed a device with vacuuming functionality. Static Load Test Bench To achieve the aforementioned objectives, the invention adopts the following technical solution: a pore-free static load testing platform, comprising a platform body and a base plate. The underside of the platform body is equipped with telescopic legs, and bearing housings are welded to the inner side of the platform body via fixing shafts. The bearing surfaces are in rolling contact with a support plate, thereby forming a test groove on the surface of the support plate. The side of the test platform body is welded to the side wall of a vertical column, and the bottom of the column is fixed to the surface of the base plate. A second hydraulic telescopic rod is secured to the central position on the base plate via bolts; the top of the second hydraulic telescopic rod presses against a lower pressing plate, which is positioned directly above the vertical column and fastened to an upper pressing plate by fixing bolts. An reinforcing plate is welded to the top of the upper pressing plate, and a work warning light is installed thereon. Static load testing platform

  Among these, a pressure gauge is provided on one side of the second hydraulic telescopic rod. Multiple sets of bearings are evenly installed within the test stand body, with all bearings aligned in the same horizontal plane. The reinforcing plate adopts a grid-like structure, with multiple mounting holes uniformly arranged at its four corners and on its top surface. Multiple sensor assemblies are mounted on the upper and lower pressure plates at the tops of the first and second hydraulic telescopic rods. Static load testing stand

  Compared with the prior art, this Static Load Test Bench It offers the following advantages: 1. Through optimized design, the number of times workers need to approach the testing machine is reduced, thereby minimizing risks; meanwhile, by using pressure and displacement sensors to measure the deformation of the template sample under different pressures, a linear relationship between deformation and mass is established, enabling accurate determination of the maximum pressure the template can withstand. The collected data are transmitted via a data cable to a computer for analysis, yielding precise test results and ensuring the overall reliability of the testing process. 2. Thanks to its optimized design, the device is equipped on both sides with fixed covers fitted with filters, which not only prevent broken fragments from flying off and causing injury but also capture dust generated during testing, thus preventing dust from interfering with the normal operation of the equipment and the sensitivity of the sensors. This design maximizes protection of the equipment’s normal operation, resulting in more accurate and reliable test outcomes.
