Abstract
The invention discloses a deep flat plate load testing device, which comprises a ground anchor, an orifice plate, a counterforce fixing device, a hydraulic cylinder and a bearing plate, wherein the ground anchor is fixed on the orifice ground, and two displacement supports and a displacement sensor are arranged on the orifice plate; the hydraulic cylinder is fixed on the bearing plate, a counterforce sleeve suit is fixed on the top of the hydraulic cylinder, and a centralizer is arranged outside a counterforce sleeve; and the top of the counterforce sleeve suit is fixed with the bottom of a counterforce beam, a displacement transfer mechanism consisting of a displacement rod and an assembly is connected to the bearing plate, and the top of the displacement transfer mechanism is in contact with the displacement sensor. The testing device is characterized in that: the displacement transfer mechanism consisting of the displacement rod and the assembly consists of left and right connecting plates fixed on the bearing plate, a displacement base fixed at the upper ends of the connecting plates and extending into the counterforce sleeve, the displacement rod connected to the central part of the base, and a displacement support which is fixed at the upper end of the displacement rod, extends out of the counterforce sleeve and is in contact with the sensor. The testing device has a simple structure and high testing precision.
Description
Technical field
The present invention relates to deep layer planar loading testing arrangement.
Background technology
High rise building foundation bottom surface buried depth can reach tens meters; The foundation soil mechanics parameter of the bearing capacity of foundation bed foundation soil and deflection is the basic foundation of foundation design, and the design of foundation is directly connected to the cost and the security reliability of whole building.Yet, can not measure the bearing capacity of underground deep layer foundation soil in the past, how data such as bearing capacity to be provided indirectly with method of testings such as laboratory test, dynamic sounding and standard injection; Because the diversity of soil property makes the data deviation that provides bigger, consequently causes construction costs to increase sometimes; Sometimes make building produce, even topple over.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide deep layer planar loading testing arrangement, it is high to deep foundation soil bearing capacity and deflection test precision.
In order to achieve the above object, the technical scheme of the present invention's employing is:
Deep layer planar loading testing arrangement; Comprise earth anchor, orifice plates and counter-force fastening devices, earth anchorage has two displacement supports and displacement transducer on ground, aperture on the orifice plates; Also comprise hydraulic jack and bearing plate; Hydraulic jack is fixed on the bearing plate, is fixed with counter-force cover group at the end face of hydraulic cylinder, and there is centralizer counter-force cover outside; The end face of counter-force cover group and the bottom surface of reaction beam fix, and on bearing plate, are connected with the displacement transmission mechanism of being made up of displacement bar and assembly, and the top of displacement transmission mechanism contacts with displacement transducer.It is characterized in that; The displacement transmission mechanism that displacement bar and assembly are formed; Be by being fixed on left and right connecting plates on the bearing plate, being fixed on the junction plate upper end and stretching into the displacement base in the counter-force cover, be connected the center position displacement bar, be fixed on the displacement bar upper end and stretch out that counter-force cover and the contacted displacement rest of sensor form.
Testing arrangement of the present invention, simple in structure, measuring accuracy is high.
