Embodiment 1

[0040] The earth pressure box embedding method process of the newly built subgrade earth pressure box embedding device is as follows:

[0041] When the filling project is carried out, first take a section of connecting rod 1, seal the bottom of the hollow threaded rod 1-1 with a sealing cover 4-2, bury the sealed connecting rod 1 in the soil to a certain depth, and weld it to the box. The earth pressure box 5 in the box setting area 2-3 of the disk 2 is connected with the connecting rod 1 through the positioning hole 2-2 on the rectangular disk 2-1 as a whole, and then adjusted to the measurement depth with the positioning nut 2-4 and fixed, and the earth pressure The wires on the box 5 are drawn from the inside of the connecting rod 1 through the part of the wire hole 1-2 in the connecting rod 1. After the filling of this layer is completed, connect the next connecting rod 1 with the sleeve 3, and install the next one that has been welded to the place. For the earth pressure ...

Abstract

The invention discloses an earth pressure box burying device and method for fill engineering. The device comprises connecting rods, a box accommodating disk, a bushing and seal covers. Each connecting rod is a hollow threaded rod, and the connecting rods of different lengths can be combined by the bushing to reach a design length; the box accommodating disk can adjust the measuring position of an earth pressure box via an adjusting nut; and the seal covers seal the top and bottom ends of the connecting rods. The method comprises that the box accommodating disk is fixed to the first connecting rod via the adjusting nut, and adjusted to a designed measuring position; the earth pressure box is fixed in a box accommodating area of the box accommodating disk in a welding manner; with increase of fill height, the second connecting rod is connected and fixed to the first connecting rod via the bushing, and the earth pressure box is mounted; and so on, all leads are led out of a bus hole and the top cover is mounted for sealing after the design fill height is reached. According to the device and method, the whole structure is simple, operation is convenient, the using effect is good, and the precision of earth pressure box burying is ensured effectively.

Description

technical field [0001] The invention relates to an earth pressure box embedding device and method for filling engineering, and belongs to the technical field of on-site construction monitoring. Background technique [0002] With the continuous advancement of infrastructure projects such as railways, highways, and earth-rock dams in my country, long-term monitoring of stress and deformation in fill engineering has become the main data source for design optimization, construction control, and maintenance. Among them, the monitoring of stress usually depends on the earth pressure cell buried in the soil. In the prior art, the burial of earth pressure cells in fill engineering generally adopts the method of directly burying the earth pressure cells in the fill, but in this method, the earth pressure cells will settle with the settlement of the fill, so that the force of the earth pressure cells Changes in the way and location of the monitoring data lead to problems such as larg...
