Test methods for static load detection

Abstract

The purpose of the invention is to provide a dead load detection test method implemented by employing a novel dead load detection tester. The method employs liquid as the counterweight material to make loading, unloading and transportation convenient, the counterweight is easy to control and capable of preventing load eccentricity, thereby greatly decreasing the test cost of the groundwork bearing capability test and increasing the security of the dead load test. The dead load detection tester is composed of a counterweight load, a load support, a jack and a detector, the counterweight load is a liquid container filled with liquid.

Description

technical field [0001] The invention relates to a test method and test equipment for static load detection of foundation bearing capacity. Background technique [0002] In the process of building construction, it is necessary to test the bearing capacity of the foundation. Among them, the static load test is the most convenient and accurate test method. In the prior art, there are usually two ways to apply load to the pile foundation in the static load test, that is, anchor pile and surcharge. In the anchor pile test, a certain number of anchor piles are first driven on the periphery of the test piles, and the pull-out force of the anchor piles provides a counter force for the beam or bracket, which is transmitted to the jack to read the load test data. The disadvantage of this test device is that the requirement for the pullout resistance of the anchor piles is very high, and the number of anchor piles is large, so the test cost is relatively high and time-consuming is ve...

Problems solved by technology

The disadvantage of this test device is that it uses steel blocks or sandbags for counterweight, which is inconvenient for loading and unloading, and difficult for transportation, which increases the cost of the test.

At the same time, in the process of solid heaping, load eccentricity is likely to occur, resulting in system instability and potential safety hazards

In addition, in the utility model patent with the announcement number 2119443U and the application number 92203746.9, there is also a test method using liquid as the load counterweight. This method still adopts the traditional load transmission method, and the liquid container is huge and difficult to transport and deploy. , and the liquid for counterweight cannot be reused to cause waste
