Problems solved by technology

The heavy blocks are usually concrete blocks, which are heavy. In actual use, the foundation needs to be reinforced or replaced on the ground where the supporting blocks are placed on both sides of the pile foundation pile to be tested, which makes the test more troublesome and needs to be improved.

Embodiment

[0041] A pile foundation static load compression test device, such as figure 1 As shown, it includes a main beam 1 and two support assemblies 2 respectively arranged at both ends of the main beam 1 . Two support assemblies 2 are respectively located on both sides of the pile foundation to be tested and are used to support the main beam 1 above the pile foundation to be tested. The lower end surface of the main beam 1 is also provided with a hydraulic cylinder 3, and the hydraulic cylinder 3 is fixed to the main beam by bolts. Beam 1 on. The hydraulic cylinder 3 is also called a hydraulic jack, and the test is carried out by applying force to the pile foundation to be measured through the hydraulic cylinder 3 .

[0042] Such as figure 1 , figure 2 As shown, each support assembly 2 includes a fixing part 21 and a connecting part 22 . The fixing part 21 includes a round rod 211 , and a helical piece 212 fixedly connected to the outer wall of the round rod 211 in a spiral sha...

Abstract

The invention discloses a pile foundation static load anti-compression test device, which relates to the technical field of building detection, and comprises a main beam arranged above the pile foundation to be tested, a hydraulic cylinder is arranged at the lower end of the main beam, and a Two supporting components for supporting the main beam, the two supporting components are respectively located on both sides of the pile foundation to be tested, the supporting components include a fixed part for inserting into the ground for fixing, and a connecting part arranged above the fixed part to connect with the main beam The fixed part includes a round rod, and a helical piece that is fixedly connected to the outer wall of the round rod in a spiral shape along the axial direction of the round rod, and the end of the fixed part away from the connecting part forms a guide part. By arranging the support assembly, the fixed part of the support assembly is fixed to the ground to form a large support force, which avoids the trouble of reinforcing or replacing the foundation, and makes the whole more convenient. In addition, the weight requirements for the main girder are greatly reduced, so that there are fewer heavy objects on the top, which reduces the increased risk of heavy object hoisting, and makes the overall test safety better.

Description

technical field [0001] The invention relates to the technical field of building detection, more specifically, it relates to a pile foundation static load compression test device. Background technique [0002] In construction engineering, it is necessary to carry out static load and compression tests on pile foundations driven into the ground to check the strength of the soil layer at the location of the building, and to check the settlement of the pile foundation per unit time under a certain load, which provides important information for construction projects. reference. When it is necessary to carry out a static load compression test on a pile foundation, a pile foundation static load compression test device is usually used. [0003] For example, the Chinese patent whose patent announcement number is CN208072486U discloses a pile foundation static load compression test device, including a support block placed on the ground, a weight positioned above the support block, a h...
