[0019] When implementing: Figure 1-5 As shown, a large-scale pile foundation bearing simulation detection device comprises: a bearing platform 1, a liquid storage tank 101 is arranged on the top of the bearing platform 1, a pressure plate 2 is arranged on the bottom of the bearing platform 1, a jack 201 is arranged between the top of the pressure plate 2 and the bearing platform 1, and a pile foundation groove is opened on the bottom of the pressure plate 2; two auxiliary components 3, both of which are arranged on the surface of the pressure plate 2, and the angle between the two auxiliary components 3 is ninety degrees; wherein, the auxiliary component 3 comprises a mounting seat 301 fixedly connected to the top of the pressure plate 2, a screw rod 303 is rotatably connected to the surface of the mounting seat 301, a connecting plate 302 is threadedly connected to the surface of the screw rod 303, and the lower end of the connecting plate 302 passes through the pressure plate 2 and is fixedly connected to a mounting plate 312 located inside the pile foundation groove.

[0020] By injecting water into the liquid storage tank 101 , the weight of the liquid storage tank 101 can be increased, so that the pile foundation can be subjected to load-bearing simulation testing through the jack 201 and the pressure plate 2 .

[0021] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the surface of the mounting plate 312 is fixedly connected with an integrally formed protrusion, the interior of the mounting plate 312 is provided with a temporary storage cavity 304, the interior of the temporary storage cavity 304 is slidably connected with a push plate 305, the surface of the push plate 305 is fixedly connected with an adjustment rod 306, the other end of the adjustment rod 306 passes through the protrusion and is fixedly connected with a trigger plate 307, the side of the push plate 305 away from the adjustment rod 306 is fixedly connected with a spring 311, the other end of the spring 311 is fixedly connected with the inner wall of the temporary storage cavity 304;

[0022] When placing the pile foundation inside the pile foundation groove, aligning it with the inner center of the pile foundation groove can make the force in the subsequent load-bearing process more uniform;

[0023] By rotating the screw rod 303, the connecting plate 302 can be driven to move, and the trigger plate 307 can be driven to contact the surface of the pile foundation to be tested. After the trigger plate 307 contacts the surface of the pile foundation, the screw rod 303 continues to rotate. Since the surface of the pile foundation blocks the trigger plate 307, the adjusting rod 306 can be driven to insert into the temporary storage cavity 304 and compress the spring 311.

[0024] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an adjusting chamber is formed between the push plate 305 away from the adjusting rod 306 and the interior of the temporary storage chamber 304, the interior of the adjusting chamber is filled with hydraulic oil, a slideway 309 is provided inside the mounting plate 312, a counterweight rod 310 is slidably connected to the inner wall of the slideway 309, the upper end of the counterweight rod 310 passes through the mounting plate 312, and a slide groove is provided on the surface of the pressure plate 2, the upper end of the counterweight rod 310 extends to the interior of the slide groove, and a connecting channel 308 connected to the adjusting chamber is provided on the inner bottom wall of the slideway 309, and two groups of indicator lines 313 are arranged on the surface of the pressure plate 2, and the two groups of indicator lines 313 are evenly distributed along the opening directions of the two groups of slideways 309 respectively;

[0025] When the adjusting rod 306 is inserted into the temporary storage chamber 304, it can drive the push plate 305 to squeeze the hydraulic oil stored in the adjusting chamber. The squeezed hydraulic oil can be injected into the interior of the slideway 309 through the connecting channel 308, thereby pushing the counterweight rod 310 to pass through the slideway, that is, the surface trigger plate 307 is in full contact with the surface of the pile foundation to be tested, and the distance between the pile foundation surface and the inner wall of the pile foundation groove can be quickly obtained in conjunction with the indicator line 313. By measuring the distance between the pile foundation surface and the inner wall of the pile foundation groove by two auxiliary components 3 with an angle of ninety degrees, it can be determined whether the pile foundation is located at the center of the pile foundation groove, so as to improve the effect of subsequent load-bearing simulation detection after adjustment.

[0026] When the utility model is in use, after the pile foundation is placed inside the pile foundation groove, the connecting plate 302 can be driven to move by rotating the screw rod 303, which can drive the trigger plate 307 to contact the surface of the pile foundation to be measured. After the trigger plate 307 contacts the surface of the pile foundation, the screw 303 continues to rotate. Since the surface of the pile foundation blocks the trigger plate 307, the adjusting rod 306 can be driven to insert into the temporary storage cavity 304 and compress the spring 311. During the process of the adjusting rod 306 being inserted into the temporary storage cavity 304, the push plate 305 can be driven to squeeze and store the spring 311 inside the adjusting cavity. The hydraulic oil squeezed can be injected into the interior of the slideway 309 through the connecting channel 308, thereby pushing the counterweight rod 310 to pass through the slideway, that is, the surface trigger plate 307 is in full contact with the surface of the pile foundation to be tested, and the distance between the pile foundation surface and the inner wall of the pile foundation groove can be quickly obtained in conjunction with the indicator line 313. By measuring the distance between the pile foundation surface and the inner wall of the pile foundation groove by two auxiliary components 3 with an included angle of ninety degrees, it can be determined whether the pile foundation is located at the center of the pile foundation groove, so as to facilitate adjustment and improve the effect of subsequent load simulation detection.

[0027] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
