Pile foundation static load compression resistance testing device

Abstract

The invention discloses a pile foundation static load compression resistance testing device, and relates to the technical field of building detection. The pile foundation static load compression resistance testing device comprises a main beam used for being arranged at the position above a to-be-tested pile foundation. A hydraulic cylinder is arranged at the lower end of the main beam. The main beam is further provided with two supporting assemblies used for supporting the main beam. The two supporting assemblies are located on the two sides of the to-be-tested pile foundation correspondingly.Each supporting assembly comprises a fixing part used for being inserted into the ground for fixation and a connecting part which is arranged above the corresponding fixing part and further connectedwith the main beam. Each fixing part comprises a round bar and a screw sheet which is spirally and fixedly connected to the outer side wall of the round bar in the axial direction of the round bar. Guiding parts are formed at the ends, far away from the connecting parts, of the fixing parts. Due to arrangement of the supporting assemblies, the fixing parts of the supporting assemblies and the ground are fixed to form large supporting force, the trouble of ground stabilization or filling replacement treatment is saved, and the pile foundation static load compression resistance testing device is made more convenient to use on the whole. In addition, the weight requirement for the main beam is greatly lowered, the number of heavy objects above is smaller, risks caused by heavy object hoisting are reduced and the overall testing safety is made 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...

AI Technical Summary

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.
