The invention provides a soil pressure box burying device suitable for a soft soil area, which is used for solving the problems that the soil body is damaged and the soil pressure detection effect is affected when the soil pressure box burying device is used for burying construction.
The device for burying the soil pressure box 200 suitable for the soft soil area comprises a burying pipe 100 and at least one pressure box 200, wherein the burying pipe 100 is provided with a soil guiding cavity 130 and a containing cavity 140, the pressure box 200 is used for detecting the soil pressure, the containing cavity 140 comprises a front plate 111 which is arranged away from the soil guiding cavity 130, and the front plate 111 is provided with at least one fixing hole 113 for fixing the pressure box 200; the lower end of the soil guiding cavity 130 forms a bottom opening 132, and when the buried pipe 100 penetrates into the soil, the excess soil enters the soil guiding cavity 130 through the bottom opening 132.
When the above-mentioned burying device for the soil pressure box 200 suitable for the soft soil area is used, the burying pipe 100 is penetrated into the soil body to be measured, and in the penetrating process, the redundant soil body is transferred to the soil guiding cavity 130 under the action of pressure; after the buried pipe 100 is penetrated, the pressure of the soil body is detected through the pressure box 200; thus, the buried pipe 100 does not generate transverse pressure on the soil body during penetration, and damage to the soil body is avoided, so that the pressure detection of the pressure box 200 on the soil body is more accurate.
Under the action of the buried pipe 100, the method is suitable for soil pressure measurement in soft soil areas, and ensures penetration of the buried pipe 100; in addition, the perpendicularity of penetration of the buried pipe 100 is improved by the cooperation of the guide plate 150.
In addition, under the action of the soil guiding cavity 130, the redundant soil body enters the soil guiding cavity 130, so that the overall weight of the buried pipe 100 is similar, and the penetrating verticality of the buried pipe 100 is improved.

The top of the soil guiding cavity 130 forms a top opening 131, so that the excessive soil entering the soil guiding cavity 130 is discharged through the top opening 131 of the soil guiding cavity 130, thereby avoiding excessive soil from affecting the penetration of the buried pipe 100.

Thus, under the action of the guide plate 150, the redundant soil body corresponding to the lower part of the accommodating cavity 140 is pushed to the bottom opening 132 of the soil guiding cavity 130 under the action of the guide plate 150 and enters the soil guiding cavity 130, so that the pressure on the soil body below when the buried pipe 100 penetrates in is reduced, the damage on the soil body is reduced, and the detection effect of the soil pressure is improved.
In addition, since the downward extension length of the front plate 111 is longer than the downward extension length of the partition plate 120, when the buried pipe 100 penetrates, the excessive soil tends to enter the soil guiding cavity 130, and the soil is facilitated to enter the soil guiding cavity 130.
