Improved deep soil pressure box mounting method

Abstract

The invention relates to the technical field of monitoring of soil pressure and discloses an improved deep soil pressure box mounting method. The improved deep soil pressure box mounting method comprises the following specific mounting steps: (1) drilling a hole in a selected buried position until the depth of the hole reaches the required depth; (2) providing a fixing device comprising a fixing plate and two fixing rings which are fixed at two ends of the fixing plate respectively, and connecting the ends of a support frame with the fixing rings; (3) forming a storage groove in the fixing device and placing a soil pressure box in the storage groove; (4) inserting the fixing device and the support frame which are connected with each other into the drilled hole according to the designed depth and direction, and inserting the lower end of the support frame into the soil; (5) backfilling the hole with coarse sand; and (6) monitoring soil pressure data according to the designed requirementafter detecting and calibrating normally. Through the improved deep soil pressure box mounting method, the support frame is used for inserting the fixing device equipped with the soil pressure box into the soil so as to prevent the soil pressure box from rotating, prevent the direction of the soil pressure box from moving, enable the soil pressure box to keep correct orientation all the time andensure the soil pressure monitoring accuracy of the soil pressure box.

Description

technical field [0001] The patent of the present invention relates to the technical field of soil pressure monitoring, in particular, to a method for improving the installation of deep soil pressure boxes. Background technique [0002] Earth pressure cells are widely used to measure the compressive stress of soil inside various structures in the field of geotechnical engineering. Earth pressure monitoring on the surface and inside the soil, and timely data acquisition equipment to obtain the required data results. [0003] At present, there are many defects in the deep earth pressure embedding methods. The embedding direction of the earth pressure cell is not easy to control, and it is easy to have deviations between the actual embedding direction and the preset direction, resulting in inaccurate monitoring data and failure to obtain the required data. [0004] Therefore, in order to meet the test requirements of the stress field of deep soil, it is urgent to solve the prob...
