Device and method for measuring soil disturbance transverse pressure in pile pipe mud entering process

Abstract

The invention relates to a device and method for measuring soil disturbance transverse pressure in a pile pipe mud entering process. The device comprises the following components: a bearing plate, a fixing sleeve, a hollow dowel bar, a soil pressure box and a soil pressure box fixing plate. The first end of the hollow dowel bar is fixedly connected with the bearing plate, the second end of the hollow dowel bar is fixedly connected with the fixing sleeve, and the hollow dowel bar and the fixing sleeve are provided with threading holes for containing soil pressure box signal lines; the soil pressure box is fixed on the soil pressure box fixing plate, the soil pressure box fixing plate is arranged in the fixing sleeve, and a data acquisition unit is installed in the soil pressure box and used for measuring opposite soil pressure and transmitting the opposite soil pressure to a controller through a signal line. According to the device for measuring the soil disturbance transverse pressure in the pile pipe mud entering process, data inaccuracy caused by displacement of the soil pressure box in the soil extrusion disturbance process can be prevented effectively.

Description

Technical field [0001] The present invention relates to a pile tube in the mud process of soil perturbation transverse pressure measuring apparatus and method, belonging to the field of piling technology. Background technique [0002] Pile pipe piling will disturb the surrounding soil during the pile of piles, and if there is an infrastructure such as other pile tubes or other pile foundations around the piling of piles, the soil disturbance in the work will inevitably There must be a certain impact. This impact requires the conclusion through experimental testing. [0003] The measurement of soil disturbance is critical in the test in the test, and the comparative situation of theoretical data and the actual data is related. A reasonably distributed measurement method can be guaranteed to obtain data in a valid impact in the effective impact in the pile pipe piling. Inventive content [0004] In response to the above protruding, the present invention provides a pile tube into t...
