Abstract
A soil pressure box fixing device of the utility model is formed by at least one surface. The surfaces are connected and form certain angles. Each surface comprises a chassis and a fixing ring fixed on the chassis. The fixing ring is provided with a gap and plural grooves. The chassis is a square iron block. The fixing ring is an iron hoop. The fixing ring and the chassis are connected through a welding mode and the chassis of the surfaces are connected through the welding mode too. When the fixing device of the utility model is installed, the soil pressure box is placed in the fixing ring of each surface; a lead wire of the pressure box is led out from the gap arranged on the fixing ring; the pressure box lead wires of the three surfaces are fixed together, numbered and led to an external portion of the soil box; an iron wire is used to fix the soil pressure box through the grooves arranged on the fixing ring; finally the soil pressure box fixing device is welded on a shield model in a simulation experiment. The structure of the soil pressure box fixing device is simple, cost is low and installation is convenient.
Description
Technical field
The utility model relates to a kind of stationary installation, says more specifically a kind of soil pressure box stationary installation.
Background technology
In the engineerings such as tunnel, shaft building, earth and rockfill dam, deep pit digging, highway, railway, ground processing and in relating to the physical simulation experiment of the soil body, often need to use the soil pressure box to carry out the measurement of soil pressure, to guarantee construction safety and to obtain scientific research data.In order to improve measuring accuracy, common type vibration wire soil pressure box needs to be fixed in certain position when mounted,, because the internal structure of type vibration wire soil pressure box is comparatively meticulous, easily is damaged, and can not directly weld, and fixedly the soil pressure box is comparatively difficult.And single soil pressure box generally can only be measured the normal pressure with its Surface Vertical, and can't try to achieve main minor stress and maximum shear on observation station, therefore needs be improved prior art.
Summary of the invention
The purpose of this utility model is that a kind of stationary installation that the soil pressure box is buried underground in groups is provided in order to solve existing issue.
Soil pressure box stationary installation of the present utility model, described stationary installation is comprised of at least one face, its each face interconnects and is angled, and each face comprises that a chassis and is fixed in the retainer plate on described chassis, and described retainer plate is provided with a breach and complex trace groove.
Described chassis is the square iron block.
Described retainer plate is iron hoop.
Be connected by welding manner between the chassis of described retainer plate and chassis and each face.
The utility model, owing to using above technical scheme, makes its effective effect that has be:
When stationary installation of the present utility model is installed, the soil pressure box is put into the retainer plate of each face, the lead-in wire of pressure cell stays in the breach of establishing and draws from retainer plate, the pressure cell of three faces lead-in wire is fixed together, number and cause native case outside, the soil pressure box is fixed by the groove that arranges on retainer plate with iron wire, finally this soil body pressure cell stationary installation is welded on the shield structure model in simulated experiment.Because this soil pressure box stationary installation is comprised of one or more surfaces, can record the soil pressure of multiple directions, can calculate according to the method for stress theory or picture stress circle the stress state at this some place, fully understand the stress situation at this some place, leaving certain gaps uncovered by the economic plan on retainer plate, make the lead-in wire of soil pressure box to pass smoothly, and the available iron silk is fixed the soil pressure box by the groove that arranges on retainer plate, making the soil pressure box is difficult drop-off, can accurately measure soil pressure again.This soil pressure box fixture structure is simple, cost is low, easy for installation.
Description of drawings
Fig. 1 is the floor map of a face of stationary installation of the present utility model;
Fig. 2 is the schematic perspective view of a face of stationary installation of the present utility model;
Fig. 3 is the schematic perspective view after three faces of stationary installation of the present utility model install the soil pressure box.
Embodiment
For the benefit of, to the understanding of structure of the present utility model, below in conjunction with drawings and Examples, describe.
With reference to shown in Figure 3, soil pressure box stationary installation of the present utility model, formed by three faces, each face is vertical and connection mutually, in conjunction with Fig. 1 and shown in Figure 2, each face comprises a chassis 1 and a retainer plate 2, chassis 1 is the square iron block, retainer plate 2 is iron hoop, retainer plate 2 is welded on chassis 1, leaves a breach 21 on retainer plate 2, makes the lead-in wire of soil pressure box to pass smoothly, and offer complex trace groove 22 on retainer plate 2, the degree of depth that the height of retainer plate 2 deducts groove 22 is the thickness of selected soil pressure box 3.
extremely shown in Figure 3 in conjunction with Fig. 1 again, when stationary installation of the present utility model is installed, soil pressure box 3 is put into the retainer plate 2 of each face, the lead-in wire of soil pressure box 3 stays in the breach 21 of establishing and draws from retainer plate 2, the lead-in wire of the soil pressure box 3 of three faces is fixed together, number and cause native case outside, by the groove 22 that arranges on retainer plate 2, that soil pressure box 3 is fixing with iron wire 4, making soil pressure box 3 is difficult drop-off, can accurately measure soil pressure again, finally this soil body pressure cell stationary installation is welded on the shield structure model in simulated experiment, completed the fixing operation of soil pressure box device, can be by the normal pressure of mounted soil pressure box 3 measurements with its Surface Vertical.
Soil pressure box fixture structure of the present utility model is simple, cost is low, easy for installation, pressure cell fixation, stable, banket front measured original pressure close to zero, do not affect the soil pressure measurement result, because these soil pressure box 3 stationary installations are comprised of one or more surfaces, can record the soil pressure of multiple directions, can calculate according to the method for stress theory or picture stress circle main minor stress and the maximum shear at this some place, fully understand the stress situation at this some place, reached the experiment Expected Results.
