Abstract
The utility model discloses a pressure box embedding device which comprises a steel pipe, a small steel disk, a large steel disk, a spring, an aircushion and a steel claw. The steel pipe and the smallsteel disk are connected through welding; the small steel disk and the small steel disk are connected via three connecting rods with the connecting parts distributed triangularly; the small steel disk and the large steel disk can move relative to the connecting rod and are provided with a spring which enables the two disks to be close to each other; the steel claw comprises a lower claw part anda cross rod part which are mutually fixed; the cross rod part is formed by bended lower claw part; the inner side of the lower claw part is movably hinged with the large steel disk, so that certain distance is left between the cross rod part and the large steel disk; the aircushion is arranged between the small steel disk and the large steel disk; the cross rod part is arranged under the aircushion; and the aircushion is connected with an external vacuum pump via a leather hose. When a pressure box is positioned in an assigned position through the device, the pressured face of the pressure boxcan keep horizontal, so that earth pressure can be tested accurately.
Description
Technical field
The utility model relates to a kind of novel pressure cell embedded device, is applicable to the civil engineering groundwork basic field.
Background technology
The important means that the vertical soil pressure test of deep layer weak soil is the field distribution of research soil stress, but because the restriction of testing arrangement can not obtain stress numerical accurately.The soil pressure tester device generally adopts earth pressure cell, is shaped as circle.Because there is bigger difference in different directions pressure, earth pressure cell certainly will influence test result as can not correctly placing.Present soil pressure is buried underground general by artificial heavy excavation mode, can only be embedded in superficial part usually.Test for the deep soil pressure, can be placed on assigned address to pressure cell on request with isolated plant then earlier with geological drilling rig boring, obtain the soil pressure test data, but burying underground of this pressure cell do not have the specialized apparatus implementation and operation, therefore often can not correctly place.
The utility model content
The utility model purpose provides a kind of pressure cell device of burying underground, with this device pressure cell is placed on assigned address and can makes the pressure cell face maintenance level that is stressed, thereby can accurately test soil pressure.
For this reason, the pressure cell embedded device that the utility model provides comprises steel pipe, little steel disc, big steel disc, spring, air cushion and steel pawl, steel pipe and little steel disc are taked welding, little steel disc is connected with the connecting rod of big steel disc by at least three connecting portion distributions triangular in shape, little steel disc can relatively move along connecting rod with big steel disc, little steel disc also disposes the spring that can impel both to press close to mutually with big steel disc, the steel pawl comprises claw and cross bar portion down, following claw and cross bar portion interfix, cross bar portion is bent to form by following claw, inboard and the big steel disc of following claw is movably hinged, this portion of being movably hinged impels cross bar portion and has certain distance between the steel disc upper surface greatly, be provided with air cushion between little steel disc and the big steel disc, cross bar portion is in below the air cushion, and this air cushion is connected by the vacuum pump of leather hose with the external world.
Because the earth pressure cell embedded device that the utility model provides can enter the soil property deep layer of boring in advance by lifting, and the air pressure that only need utilize vacuum pump control air cushion just can realize pressure firmly grasp and unclamp, for example little steel disc and big steel disc are strutted when vacuum pump air cushion when air cushion is inflated, also oppress simultaneously the cross bar portion of steel pawl, cross bar portion pressurized can further impel down, and claw outwards opens, can live pressure cell this moment with the steel pawl casing, then stop to exert pressure to air cushion with vacuum pump, this moment, air cushion shrank gradually, simultaneously big steel disc is subjected to the tension effect of spring upwards to oppress the cross bar portion of steel pawl (so because little steel disc is fixed on the steel pipe can only be that big steel disc moves), the following claw of final steel pawl draws promptly pressure cell in, when carrying the arrival precalculated position, pressure cell only needs to unclamp pressure cell to the air cushion inflation, this pressure cell embedded device can accurately be buried pressure cell on request underground, obtain reliably vertical soil pressure data, for design or researcher provide foundation.
