Description

Technical Field

[0001] This utility model relates to the field of static cone penetration testing technology, specifically to a static cone penetration testing platform. Background Technology

[0002] Static cone penetration testing (CPPT) involves using a pressure device to press a probe with a probe tip into a test soil layer. By systematically measuring the penetration resistance, it determines certain fundamental physical and mechanical properties of the soil, such as its deformation modulus and allowable bearing capacity. In engineering surveys, CPPT is both an in-situ testing method and an important exploration technique. Compared to conventional exploration procedures such as drilling, sampling, and laboratory testing, it is faster, more accurate, more economical, and saves manpower. It is widely used for classifying soil layers, determining the engineering properties of each soil layer, and determining pile foundation parameters. However, when conducting CPPT operations in aquatic environments, the buoyancy of traditional CPPT platforms often makes it difficult to provide a sufficiently stable penetration force. Insufficient platform stability leads to inaccurate test data and low operational efficiency. Utility Model Content

[0027] See Figures 1 to 3 This embodiment discloses a static cone penetration test platform, including an operating platform 1, outriggers 2, anti-slip plates 3, a protective pipe 4, a float 5, and a submersible pump (not shown in the figure). Outriggers 2 are provided at each of the four corners of the operating platform 1. Multiple sets of anti-slip plates 3 are detachably installed on the operating platform 1. The protective pipe 4 is vertically fixed on the operating platform 1 and penetrates through the operating platform 1. The protective pipe 4 provides an axial channel for the probe rod of the static cone penetration test equipment to pass through, which is used to guide the static cone penetration test equipment into the soil and protect the static cone penetration test equipment from damage.

[0028] The pontoon 5 includes a horizontal pontoon 51 and a vertical pontoon 52. The horizontal pontoon 51 is installed inside the operating platform 1, and the vertical pontoon 52 is installed at the four corners of the operating platform 1. The upper end of the vertical pontoon 52 is open. The submersible pump is used to fill or pump water into the vertical pontoon 52. The horizontal pontoon 51 and the vertical pontoon 52 provide buoyancy to the platform and the necessary penetration reaction force during penetration, ensuring the accuracy of the test depth and data.

[0029] In this embodiment, the float 5 has a capacity of 200L, a diameter of 600mm, a height of 980mm, a loading port diameter of 470mm, and a weight of 10.5kg; the submersible pump has a flow rate of 8m³ / h. 3 / s, water loading can usually be completed in 10 minutes.

[0030] The operating platform 1 includes two sets of sub-platforms 11 and connecting parts 12. Each sub-platform 11 is composed of a hollow frame structure made of multiple sets of angle steel. The two sets of sub-platforms 12 are connected by multiple sets of connecting parts 12. The anti-slip plate 3 is detachably installed between the two sets of sub-platforms 11. Each end of each sub-platform 11 is provided with a support leg 2 and a vertical float 52. Each sub-platform 11 has multiple sets of horizontal floats 51 arranged side by side. The two sets of sub-platforms 11 form an overall operating platform 1, which enhances the stability and strength of the platform and enables it to maintain a horizontal state in the water environment.

[0031] Furthermore, each of the four corners of the operating platform 1 is welded with a pontoon frame 101, and the vertical pontoon 52 is set inside the pontoon frame 101.

[0032] In this embodiment, the operating platform 1 is 2500mm long and 2500mm wide, and the sub-platform 11 is welded from a 20×20×3mm angle steel frame and HPB300 round steel bars with a diameter of 6mm in the shape of a 2500×994×610mm cuboid.

[0033] The outrigger 2 includes a fixed leg 21, an upper outrigger 22, and a ground anchor 23. The fixed leg 21 is welded to the four angles of the operating platform 1 using plain round steel bars. Specifically, the fixed leg 21 is welded to both ends of each sub-platform 11. The top of the fixed leg 21 is threaded to the upper outrigger 22, and the bottom is threaded to the ground anchor 23, allowing the outrigger 2 to be detachably installed for convenient transportation of the platform. The ground anchor 23 can be firmly fixed to the bottom of the river or ditch, thus securing the platform. Utilizing the weight of the water filling the vertical buoy 52 as a penetration reaction force, the ground anchor 23 transfers the upper load to the bottom of the river or ditch, resulting in strong overall balance and high working efficiency of the platform.

[0034] The anti-slip plate 3 is a galvanized steel grating anti-slip plate. The grating mesh size of the galvanized steel grating anti-slip plate is 20×100mm, and the size of a single steel grating plate is 508×1382mm, with a height of 20mm. By laying the anti-slip plate 3 on this platform, it has the advantages of anti-slip, strong load-bearing capacity, good corrosion resistance, ventilation and light transmission, easy cleaning, and aesthetics and durability, while also reducing the overall weight of the platform.

[0035] The protective tube 4 is vertically fixed to and passes through the connector 12. In this embodiment, the protective tube is composed of multiple sets of galvanized protective tubes coaxially connected. During the penetration of the probe rod of the static cone penetrometer, the protective tube 5 can provide lateral restraint force to prevent the probe rod from breaking and increase the penetration depth.

[0036] The working principle of this embodiment is as follows: First, the anti-slip plate 3, buoy 5, and sub-platform 11 are assembled and fixed on the riverbank, completing the construction of the operating platform 1. The distance from the river surface to the hard layer of the riverbed is measured, and a fixed leg 21 of appropriate length is selected. Then, the device is transported to the river, and the support legs 22, ground anchors 23, and protective pipes 4 are installed. The ground anchors 23 are fixed to the riverbed, and the submersible pump is turned on to fill the vertical buoy 52 with water to increase the load, thus beginning the hydrostatic cone penetration test. At the end, the water in the vertical buoy 52 is pumped out, the probe is pulled out using the hydrostatic cone penetration test equipment, and the device is towed back to the shore for disassembly, cleaning, and maintenance, thus ending the test.

[0037] In summary, this embodiment features a simple structure and quick installation, which not only ensures the accuracy of survey data and accelerates construction progress but also improves work efficiency and saves costs.
