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

Embodiment 1

[0046] Such as figure 1 As shown, a bushing assembly for installation of a deep-buried earth pressure cell, the bushing assembly includes several bushings 1, the bushings 1 are square pipes and the bushings 1 are made of PVC. Such as figure 2 As shown, a first connecting piece 2 and a second connecting piece 3 are respectively fixedly arranged at both ends of the sleeve 1 . Such as image 3 As shown, the lowermost casing 1 is only provided with the first connecting piece 2 , and the uppermost casing 1 is only provided with the second connecting piece 3 . Such as figure 2 As shown, the outer wall of the first connector 2 is provided with external threads, and the inner wall of the second connector 3 is provided with internal threads. The first connecting part 2 of the bushing 1 can be screwed to the second connecting part 3 of another bushing 1 . Such as image 3 As shown, when two bushings 1 need to be connected, it is only necessary to screw the first connecting part ...

Embodiment 2

[0052] An installation process for a deep-buried earth pressure cell is characterized in that: the casing 1 in the first embodiment is used, and the steps are as follows,

[0053] S1. Embed and install the earth pressure cell 11 into the installation hole 7, so that the earth pressure cell 11 is fixedly installed on the casing 1, and the axial direction of the earth pressure cell 11 is perpendicular to the axial direction of the casing 1; at the same time, the first clamping plate 8 and The second clamping plate 9 presses against the earth pressure box 11 synchronously under the action of the pressing spring 10, so that the earth pressure box 11 is installed in the casing 1 more stably;

[0054] S2. Arrange all the bushings 1, and then pass the cable 12 on the earth pressure box 11 through all the bushings 1, so that the upper end of the cable 12 passes through the uppermost bushing 1, and then put all the bushings 1 The sections are fixedly installed together; such as image...

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 cell. Background technique [0002] The deep-buried earth pressure cell is used to measure the change of mechanical parameters of various soil layers below the surface. Measure the change of soil pressure at different depths of the undisturbed soil, give early warning, and ensure construction safety. [0003] The current earth pressure box embedding method is mainly to use hanging cloth to cover the side of the reinforcement cage, then bind the earth pressure box and cables with iron wires, and the cables are bundled to extend about 1.5 meters to the top of the reinforcement cage. 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, whi...
