Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of structural engineering, in particular to a rapid installation flat plate experiment support structure for a molten salt energy storage heat preservation foundation. BACKGROUND

[0002] In the construction of a molten salt energy storage heat preservation foundation, compaction of ceramsite and detection of deformation modulus are experiments that are often needed. After the ceramsite is compacted in layers, this experiment can be used to measure the bearing capacity, ground coefficient, and deformation modulus of each layer of ceramsite under the foundation of a molten salt storage tank. The current flat plate load experiment is suitable for measuring the bearing capacity and deformation modulus of each layer of ceramsite under the bearing plate of the foundation. In addition to the measurement instrument, the main items of the flat plate load experiment also include the support part.

[0003] The traditional reference beam support in the prior art is a steel pipe fastener assembled into a shape or a concrete support pier used as a reference beam support to complete the experimental detection task. However, the traditional support has the disadvantages of complicated disassembly and assembly, large size, and low efficiency. In order to facilitate the experiment, a concrete support pier is usually used as a reference beam support on site. However, the construction of a concrete support pier usually requires at least six concrete blocks, with a mass of more than 10 tons. The hoisting process is relatively slow, and there is an additional safety risk in hoisting heavy objects. At the same time, the concrete support pier occupies a large area and has a large mass, which can easily cause data errors in the surrounding area. The concrete itself has a large mass and has a certain compaction effect on the roadbed, which itself achieves the effect of compaction and has a certain impact on the test area. Thus, the data obtained has certain errors, and the hoisting requires a lot of manpower and resources, and the efficiency and economic value still need to be improved.

[0004] In the invention patent application for a device and method for detecting the bearing capacity of a water conservancy engineering foundation with publication number CN118745727A and the name of the device and method for detecting the bearing capacity of a water conservancy engineering foundation, two bottom plates are provided, a special steel plate is placed between the two bottom plates, a flat plate load instrument is placed on the special steel plate, the flat plate load instrument is located at the center of the top surface of the special steel plate, an iron frame is provided above the two bottom plates, and an iron frame, a first sliding bar, and a guide rail are also provided. When in use, the flat plate load instrument is first fixed at the detection point, and then the crane moves the iron frame and the bottom plate above the flat plate load instrument and releases them downward. Since the iron frame and the bottom plate are connected through the sliding bar, the flat plate load instrument gradually lifts the iron frame during the downward movement, forcing it to separate from the bottom plate.

[0005] The above application includes a flat plate experiment support structure, but the support structure concentrates weight on the middle detector during installation, and the pre-pressing requirement during detection of the ceramsite in the storage tank is generally required to be less than 0.01 MPa, the support structure during installation exceeds the pre-pressing standard and affects the detection; and the main stress end of the support structure is an auxiliary jack, the jack is heavy, and it is time-consuming and laborious to carry.
