Compression resistance static loading test system for foundation

Abstract

The invention provides a compression resistance static loading test system for a foundation. The static loading test system comprises a platform, a cab, an engine unit, a motor hydraulic pump, two rotating platforms, two long ships and two inner ships. The platform is used for bearing ballasting, and the middle of the upper end of the platform is provided with a main side oil cylinder; the cab is arranged on one side of the platform, and the engine unit and the motor hydraulic pump are arranged on the other side of the platform; the two rotating platforms are connected with the platform through connecting shafts; the two long ships are connected with the side faces at the two ends of the platform through connecting pieces respectively and respectively comprise a long ship safe buttress, and the long ships are connected with the connecting pieces through long ship supporting legs; the two inner ships are connected with the two ends of the rotating platforms respectively, each inner ship comprises an inner safe buttress, two inner ship track side plates arranged on the inner safe buttress, an inner ship track groove, a sideway oil cylinder arranged in the inner ship track groove and inner ship support legs arranged in the inner ship track groove in a sliding mode. The static loading test system is high in security coefficient, labor efficiency and automation degree and can ensure normalized construction.

Description

[0001] technical field [0002] The invention relates to the field of foundation detection, in particular to a foundation foundation anti-compression static load test system. [0003] Background technique [0004] The anti-static static load test of the foundation (hereinafter referred to as the static load test) is a test method that applies pressure step by step on the top surface of the inspected part and measures its settlement over time to determine the bearing capacity. It is the most recognized test method in foundation testing. Intuitive, reliable, and above all traditional methods. [0005] At present, due to the limitation of site conditions, the static load test mainly uses the ballast platform reaction device, refer to figure 1 , the detection process is as follows: [0006] 1) Handle the inspected part according to the actual situation on site, level the surrounding foundation surface 1a, and reinforce the foundation soil within the influence range of the saf...

AI Technical Summary

Problems solved by technology

In actual work, it is rare that the foundation soil under the safety pier 2a can be effectively treated in place, and it is difficult to make the grounding area of ​​the safety pier 2a large enough due to the limitation of equipment capacity

In special site conditions, during the erection of the reaction device and the test process, the reaction device will often be eccentric, tilted or even unstable and collapsed, causing safety problems for on-site inspection personnel and surrounding personnel and facilities

[0017] 2. Efficiency issues

[0018] a) The test of each inspected part needs to use the crane to repeatedly disassemble and assemble all the test equipment. If the next inspected part is far away, it often needs to be turned over by the crane multiple times or transferred by truck, which wastes time and increases costs, and the efficiency is low ;

[0019] b) Cranes and trucks have relatively high requirements on the working environment, and often cannot work because a certain condition is not in place;

[0020] c) Repeated disassembly and assembly of pressure control equipment and measuring instruments (especially when static load automatic detection equipment is used) increases the failure rate, reduces stability, and will also have a certain impact on efficiency

[0021] 3. Standardization issues

[0028] 4. Effective supervision issues

However, relying solely on the regulatory platform cannot achieve the goal very well. There are mainly the following problems:

[0033] d) Does not reflect well the normative nature of the on-site process
