An installation process for deep-buried earth pressure cells

Abstract

The invention discloses an installation process used for deeply-buried earth pressure cells. The installation process used for the deeply-buried earth pressure cells comprises the following steps thatS1, casing pipes provided with installation holes are selected; S2, the earth pressure cells are arranged in the installation holes in an embedded manner to be fixedly arranged on the casing pipes, and the axial directions of the earth pressure cells are perpendicular to the axial directions of the casing pipes; S3, all the casing pipes are arranged one by one in the axial directions of the casing pipes, a cable corresponding to the earth pressure cells penetrates the casing pipes, the upper end of the cable penetrates out of the upmost casing pipe, and the lower end of the lowest casing pipeis closed; S4, all the casing pipes are fixedly installed together in the axial directions of the casing pipes; S5, the casing pipes are full of standard sand, and the standard sand is compacted; S6,drilling mechanical equipment is adopted to drill a hole with enough depth; and S7, the casing pipes with the earth pressure cells are sequentially put into the holes, and gaps on the outer sides ofthe casing pipes are full of standard sand. The casing pipes play a role in limiting the earth pressure cells, so that the earth pressure cells can be stably buried in the soil layer, and errors, caused by overturning of the earth pressure cells, of measured data is prevented.

Description

Technical field [0001] The invention relates to the technical field of construction engineering, in particular to an installation process for a deep buried earth pressure box. Background technique [0002] The deep-buried earth pressure cell is used to measure the changes of the mechanical parameters of various soil layers below the surface. Measure the earth pressure changes at different depths of the undisturbed soil, and provide early warning to ensure construction safety. [0003] The current method of burying the ground connecting wall pressure box is to first use hanging cloth to cover the side of the steel cage, and then tie the earth pressure box and the cable with iron wire, and the cable is tied to the top of the steel cage to extend about 1.5 meters. Because the earth pressure box is mostly round, it is difficult to bundle it, which will easily cause the pressure box to turn over and cause the subsequent monitoring data to be untrue; in addition, the cable lines are all...

AI Technical Summary

Problems solved by technology

Because the earth pressure box is mostly round, it is difficult to tie it up, which may easily cause the pressure box to overturn, resulting in untrue monitoring data in the future; in addition, the cables are all bare wires, which are easy to cut off the line or due to friction with the surrounding hard objects. Cause the cable to break, thus affecting the monitoring quality
