Abstract

The invention discloses a counter force device and method used for an oblique static force penetration test inside a tunnel. Two pieces of first box iron are installed on the two sides of the bottom of a static force penetration testing machine frame. Webs at the two ends of the two pieces of first box iron are fixedly connected through steel pipes. Two pieces of second box iron are symmetrically and fixedly erected between the top faces of the two pieces of first box iron in a crossing mode. The two pieces of second box iron are located over the steel pipes. The two pieces of second box iron are each provided with a pressing plate assembly and a counter force supporting adjusting assembly. Each pressing plate assembly comprises angle iron and a pressing plate. Each counter force supporting adjusting assembly comprises a fixing pipe, a threaded rod and two limiting nuts. According to the counter force device, bolts and bolt holes of concrete segments of subway tunnel linings are sufficiently utilized, oblique and horizontal static force penetration tests can be conducted, the safety of the test process is guaranteed, and the defects in the process that an existing counter force device is used for conducting the static force penetration test in the tunnel are overcome.

Description

technical field [0001] The invention relates to a counterforce device and method for oblique static penetration tests inside tunnels, which are used for static penetration tests in subway tunnels. Background technique [0002] The static penetration test is a test that uses a double-bridge probe or a three-bridge probe to penetrate the soil on the ground. This test can record the cone tip resistance, side wall resistance and pore water of the probe during its downward penetration into the soil layer. Pressure, through these parameters can have a preliminary understanding of the properties of the soil. To penetrate the probe into the soil, a counter force device must be set up to provide the counter force required for the penetration process. [0003] In the current technology, the spiral ground anchor is usually rotated and inserted into the soil body through a hydraulic device, and then the reaction beam is fixed on the ground anchor through bolts, and then the press-in po...
