Description

Technical Field

[0001] This utility model relates to the field of in-situ testing technology for reinforced piers, specifically an in-situ testing device for soft soil reinforced piers that takes into account the influence of plateau climate. Background Technology

[0002] In-situ testing of reinforced piers refers to the process of directly evaluating the physical and mechanical properties and engineering performance of the reinforced pier and its surrounding soil layers through on-site tests and inspections after the construction of reinforced piers (such as dynamic compaction piers and cement-soil mixing piles). This testing method emphasizes conducting the tests at the actual location and in-situ conditions of the pier to reflect the authenticity of the reinforcement effect to the greatest extent.

[0003] Static load tests involve applying a load to the top of the reinforced pier, observing the settlement of the pier and the surrounding soil, and calculating the bearing capacity and deformation modulus of the foundation. However, in high-altitude climates, due to low temperatures, frozen soil may exist. Testing under these conditions will result in a significantly lower overall settlement. In hot weather, the settlement will increase dramatically due to the thawing of frozen soil. In actual testing, in-situ testing after thawing is often necessary to obtain accurate data. Direct testing without human intervention requires waiting for suitable weather conditions. Testing can only be conducted when the frozen soil thaws due to warmer weather, which limits its effectiveness. Utility Model Content

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.

[0017] Please see Figure 1-3 This utility model provides a technical solution: including a carrier plate 1, a counterweight 11, and a heating rod 5. The carrier plate 1 is set above an adjacent reinforced pier, the counterweight 11 is set above the carrier plate 1, the bottom of the heating rod 5 is inserted below the soft soil surface and is distributed around the periphery of the reinforced pier, a connecting pipe 6 is installed between the upper ends of adjacent heating rods 5, a circulation pipe 8 is installed on the end of the heating rod 5, and the end of the circulation pipe 8 is installed on a heater 7. An installation plate 3 is set on the ground directly below the carrier plate 1, and a laser rangefinder 31 is set on the installation plate 3.

[0018] A heat insulation frame 4 is provided around the heating rod 5. A sealing cover 42 is installed on the upper end of the heat insulation frame 4. Both the heat insulation frame 4 and the sealing cover 42 are provided with heat insulation lining. An outer edge plate 41 is fixed to the outer side of the bottom of the heat insulation frame 4. A spiral hole is provided inside the heating rod 5, and the openings at both ends are located at the upper end of the heating rod 5. The heating rod 5 consists of an upper end head 51 and an insertion rod 52. The upper end head 51 is fixed to the upper end of the insertion rod 52. A connector 54 is fixed to the upper end of the upper end head 51 and aligned with the opening of the spiral hole. The ends of the connecting pipe 6 and the circulation pipe 8 are installed on the connector 54. Heat sinks 53 are evenly fixed to the outer side of the insertion rod 52.

[0019] A water tank is installed inside the heater 7, and the end of the circulation pipe 8 is located inside the water tank. A circulation pump 71 is fixed on the heater 7 and at the corresponding position of the circulation pipe 8. Both the connecting pipe 6 and the circulation pipe 8 are metal flexible hoses. The ends of the connecting pipe 6 and the circulation pipe 8 are threaded onto the connector 54, and a sealing anti-slip pad is provided at the connection.

[0020] Working principle: First, the carrier plate 1 is installed above the adjacent reinforcement pier. Then, the mounting plate 3 is placed on the ground below the carrier plate 1. Next, counterweights 11 are stacked on the carrier plate 1. The weight of the counterweights 11 presses down, squeezing the reinforcement pier downwards. When settlement occurs, a laser rangefinder 31 can be used for measurement, achieving in-situ detection. Then, heating rods 5 are inserted into the ground in sequence, evenly distributed around the perimeter of the reinforcement pier. The connecting pipe 6 is used to connect the connector 54 at the top of the heating rod 5, and the circulation pipe 8 at the end is connected to the inlet and outlet of the heater 7. The system utilizes a water tank within heater 7 to heat the ground, and a circulating pump 71 continuously delivers hot water to the circulating pipe 8 and heating rod 5, enabling rapid heating of the ground. In the case of frozen soil in high-altitude areas, artificial heating can be used to achieve rapid thawing, eliminating the need to wait for high temperatures before testing and reducing testing limitations. Furthermore, heat dissipation fins 53 are installed at the part of the heating rod 5 that is inserted into the ground, allowing heat to be transferred to the ground more quickly and increasing the heating rate. At the same time, the insulation frame 4 isolates the testing area, reducing the impact of the external environment on the testing area and thus achieving effective energy saving.
