An Indoor Inclined Static Penetration Model Test Device

Abstract

The invention relates to an indoor inclined static cone penetration model test device which is applied to a civil engineering indoor static cone penetration model test. The indoor inclined static cone penetration model test device comprises a penetration system, a sliding device and a test model box. The penetration system comprises a mechanical part and a power part. The mechanical part comprises an angle adjusting support, a static cone penetration rod, a static cone penetration frame, a chain and a gear transmission device, wherein the angle adjusting support, the static cone penetration rod, the static cone penetration frame, the chain and the gear transmission device are connected in sequence. The power part comprises a three-phase asynchronous motor and a variable-frequency governor, wherein the three-phase asynchronous motor and the variable-frequency governor are connected with each other. The sliding device comprises U-steels, square steels and ball bearings, wherein each ball bearing is connected on one U-steel and one square steel. A bottom plate of the test model box is a steel plate, organic glass surrounds the bottom plate, and the bottom plate is connected with the periphery in a sealing mode. In addition, a peripheral skeleton of the test model box is made of angle steel in a welded mode so that the stability of the test model box can be guaranteed. The indoor inclined static cone penetration model test device can achieve the purposes that a penetration test can be conducted at any position of the horizontal plane of the test model box, the penetration rate can be controlled within a certain speed range, and constant speed can be kept. Besides, compared with conventional equipment which can only conduct a vertical static cone penetration test, the indoor inclined static cone penetration model test device can achieve an inclined static cone penetration test within a range of a certain angle of inclination.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and relates to indoor static penetrating sounding model test equipment used in civil engineering, in particular to test equipment that can effectively obtain formation strength and other information when in-situ testing is difficult. Background technique [0002] Static Cone Penetration Test (CPT for short) is to use quasi-static force to press a conical probe of a certain size and shape into the soil through a series of probes at a constant penetration rate, and at the same time measure the impact on the probe during the penetration process. It is a field test method to indirectly determine the physical and mechanical properties of soil according to the measured penetration resistance. [0003] The static penetration test is widely used in on-site testing and testing. It has the characteristics of fast, accurate, economical and manpower-saving. It can continuously obtain the strength o...
