Description
Technical Field
[0001] The utility model belongs to the technical field related to soil pressure measurement, and specifically relates to a soil pressure measuring device. Background Art
[0002] Earth pressure refers to the force exerted by the soil on a building or structure. Among them, the thrust of the soil that can cause the movement of a building or structure is called active earth pressure; the resistance of the soil that can prevent the movement of a building or structure is called passive earth pressure. In order to measure the static side pressure coefficient, it is usually necessary to obtain the horizontal earth pressure and the vertical earth pressure. Usually, the earth pressure box is buried in the test position with the help of a burying device to achieve the measurement of earth pressure. Existing earth pressure detection boxes are mostly judged by the pressure borne by the detection device. The earth pressure detection box is buried underground. Affected by the burial process and ground settlement, the detection box is prone to tilt, which in turn affects the pressure measurement accuracy.
[0003] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION
[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.
[0022] like Figures 1 to 4 As shown, a soil pressure measuring device comprises a detection box body 1 and a film sheet 3 sealed and arranged above the detection box body 1, a sealing partition 9 is arranged near the lower part of the detection box body 1, an air pressure sensor 7 is fixedly installed above the sealing partition 9, a tilt sensor 17 is installed on the side of the air pressure sensor 7, and a temperature sensor 8 is arranged on the side of the tilt sensor 17, a mounting groove 14 is opened on the upper end surface of the detection box body 1, a fixed matching ring frame 16 is fixedly arranged on the outer side of the film sheet 3, a matching sealing gasket 15 is arranged in the mounting groove 14, and the size specification of the matching sealing gasket 15 is mutually adapted to the mounting groove 14, and an upper fixed locking ring 4 is fixedly arranged on the fixed matching ring frame 16 for fixing and installing the fixed matching ring frame 16 and the film sheet 3.
[0023] Among them, the fixed matching ring frame 16 is an F-type structure, the fixed matching ring frame 16 and the film 3 are sealed, and the upper fixed locking ring 4 and the detection box body 1 are fixedly connected by fixing screws 13 to achieve sealing and fixed installation of the film 3.
[0024] Side ears 2 are fixedly arranged on both sides of the upper part of the detection box body 1, and fixing holes 5 are opened on the side ears 2. The arrangement of the side ears 2 makes it easy to press down the detection box body 1 for fixed installation.
[0025] Four installation pins 6 are fixedly arranged at the bottom of the detection box body 1. The installation pins 6 are arranged in a conical structure, which is convenient for being inserted into the installation position.
[0026] A battery module 10 is arranged below the sealing partition 9. A threading hole 11 is opened on the side wall of the detection box body 1 on the side of the battery module 10. A sealing sleeve 12 is arranged in the threading hole 11. The threading hole 11 is used to pass signal lines and power lines to realize signal transmission.
[0027] The working principle of the utility model is as follows: when measuring soil pressure, the detection box body 1 is placed at the position where the soil pressure measurement is to be carried out, and the setting of the installation pin 6 is convenient for the fixed installation of the detection box body 1, and the fixing hole 5 on the side ear 2 can be used in conjunction with the nail for auxiliary fixing. The setting of the side ear 2 is convenient for using tools to press down the detection box body 1 to increase the force-bearing area. After the detection box body 1 is installed, it is buried in the soil. After being buried in the soil, the film sheet 3 will be squeezed and deformed due to the pressure, resulting in changes in the air pressure in the sealed cavity in the detection box body 1. The air pressure sensor 7 in the detection box body 1 can monitor the air pressure in real time. Since the air pressure is also affected by the temperature, the temperature in the sealed cavity can be detected by the temperature sensor 8, and then the detection result can be corrected and compensated. At the same time, the sealing partition 9 is provided with an inclination sensor 17 to monitor the state of the detection box body 1, whether it is tilted due to the influence of land settlement, and perform force decomposition compensation during the conversion process, thereby ensuring the accuracy of the soil pressure measurement result.
[0028] The novel structure of the present invention is reasonably designed and easy to install and use. An air pressure sensor 7, a temperature sensor 8 and an inclination sensor 17 are installed in the sealed cavity in the detection box main body 1. The soil presses on the film sheet 3, causing the film sheet 3 to deform, resulting in changes in the air pressure in the sealed cavity of the detection box main body 1. The air pressure sensor 7 detects the change in air pressure and then converts it into the soil pressure. The inclination sensor 17 can detect the change in the position state of the detection box main body 1 and then decompose the force. The temperature sensor 8 can detect the temperature change and then compensate for the air pressure change caused by the temperature change to ensure the accuracy of the detection result.
[0029] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form.
