Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to a bearing capacity testing device for a rigid composite pile. Background Art

[0002] A rigid composite pile is a pile foundation formed by combining concrete pipe piles and mixing piles through prestressing technology. It has high bearing capacity and lateral deformation resistance. In order to evaluate the bearing capacity of the pile body and ensure the stability of the building, its bearing capacity needs to be tested. This solution specifically involves a rigid composite pile bearing capacity test device;

The jack is prone to slide and cause deviation. During the test, the counterweight is prone to rolling and sliding, which makes it inconvenient to position and protect the load-bearing plate and the counterweight, thus having a certain impact on actual use.

[0023] In this embodiment, the two supports 3 are symmetrically arranged, and the two ends of the beam 5 are respectively located in the two limit grooves 4 and matched with each other. The beam 5 is clamped through the limit grooves 4 and is located on the top of the pile body and the jack 6, so that the gravity of the two supports 3 is concentrated on the jack 6.

[0024] In this embodiment, the top end of the jack 6 is located in two positioning rings 7 and matched with each other. The inner surface of the clamping block 10 is arc-shaped. The jack 6 is positioned by the positioning rings 7 and the clamping block 10 to prevent displacement and sliding.

[0025] In this embodiment, the screw rod 9 passes through the interior of the fixed block 8 and is threadedly connected. The inner end of the screw rod 9 passes through the interior of the clamping block 10 and is connected via a bearing. The clamping block 10 is driven to slide by the rotation of the screw rod 9 under the action of the thread to adjust the clamping degree.

[0026] In this embodiment, the positioning mechanism 2 includes two supports 12 and a load-bearing plate 17. The two supports 12 are fixedly installed on both sides of the bottom of the load-bearing plate 17. Two guide rods 13 are movably installed between the two supports 12. Adjustment rods 14 are installed at both ends of the two guide rods 13 and pass through the interior of the two supports 12.
